Keysight Technologies PSG Signal Generators mm-wav
Keysight Technologiesmm-wave Source Modulesfrom OML, Inc. for PSG Signal GeneratorsTechnical OverviewHigh performance mm-wave source modules extend the frequency coverage of the PSG to 500 GHz.The Keysight Technologies, Inc. PSG signal generators (PSG) provide excellent signal power, resolution, stability, and analog modulation performance for coaxial applications to 67 GHz. Now, when paired with new, high power mm-wave source modules from OML, Inc., much of the PSG’s capability can be extended up to 500 GHz to meet the require-ments of emerging mm-wave applications.Characteristics of the millimeter-wave spectrumWhile it is generally recognized that mm-wave frequencies are between 30 GHz and 300 GHz, factors such as broadband solid state microwave electronics, relatively low atmospheric absorption of signals < 50 GHz, the need for high communication band-widths, and advances in coax transmission capabilities have allowed the microwave band to virtually encompass the 30 GHz to 50 GHz frequency applications.The mm-wave spectrum beyond 50 GHz offers many advantages to certain applica-tions. Millimeter-wave wavelengths are small (< 10 mm) which means mm components are smaller than microwave components. This in turn results in smaller, more focused transmit and receive antennas – with apertures that have narrower beam widths and transmissions that suffer less losses in the presence of rain, smoke, fog, and dust. Atmospheric constituents and gases attenuate millimeter signals at different rates for different frequencies. Overall, there are narrow regions (bands) of high signal absorption and wide regions of low signal absorption that occur over the entire millimeter frequency range. The low absorption bands provide sufficient bandwidth for localized applications such as automotive collision radar or autonomous cruise control (77, 94 GHz), broadband gigabit wireless communications (70 to 86 GHz), non-ionic imaging (110 to 300 GHz), material characterization and chemical sensing (225 to 310 GHz).Figure 1. Atmospheric absorption of millimeter waves.Solving your mm-wave signal source needsMillimeter wave sources are essential instruments for developing almost all millimeter wave systems and for extending the range of microwave systems. The SxxMS-AG series of high power, frequency banded mm-wave source modules from OML, Inc., when driven by Keysight’s high performance PSG, provide synthesized mm-wave test signals for waveguide bands from 50 to 500 GHz. The SxxMS-AG series have RF input power protection allowing all PSG’s with high output power (Option 1EU or 1EA) to drive mm-wave source modules without the need for external RF power amplifiers. In addition, the SxxMS-AG series were designed to derive DC power directly from the PSG (through the source-module-interface connector), and eliminates the need for an external DC power supply.High accuracy and resolutionBecause the SxxMS-AG series modules employ frequency multiplication to generate mm-wave frequencies, the output frequency specifications are directly proportional to the characteristics of the PSG driving the module. The PSG’s frequency resolution is typically in the millihertz range, which allows a mm-wave carrier frequency of 500 GHz to have a frequency resolution of < 1 Hz.Spectral PurityThe SxxMS-AG series mm-wave source modules offer harmonic, sub-harmonic, and spurious suppression of > 20 dBc, in any band. The high stability and low phase noise performance of the PSG is raised by a factor of 20 log N, where N is the multiplier factor of the specific module. For the eight SxxMS-AG series modules, N varies from 4 (50 to 75 GHz model) to 30 (325 to 500 GHz model) and 20 log N varies from 12 dB (50 to 75 GHz) to 18 dB (90 to 140 GHz) to 30 dB (325 to 500 GHz).-160-140-120-100-80-60-40-2001101001,00010,000100,0001,000,00010,000,000P h a s e n o i s e (d B c /H z )Frequency offset from carrier (Hz)PSG phase noise vs. frequencydue to 20log(n) multiplication (SxxMS-AG)PSG (15 GHz)60 GHz (15 GHz x4)90 GHz (15 GHz x6)120 GHz (15 GHz x8)180 GHz (15 GHz x12)270 GHz (15 GHz x18)450 GHz (15 GHz x30)Figure 2. Typical phase noise performance of PSG with OML S10MS-AG module at different carrier frequencies.Output PowerThe SxxMS-AG series modules offer substantial fixed output power, allowing them to be used as LO's in mixer measurements and provides additional dynamic range for insertion loss/gain measurements. For example, the W-band performance shown in Figure 3 demonstrates a measured output power of +7 dBm with typical output power flatness of ± 1 dB.The output signal power is fixed and can only be varied through the use of an external fixed attenuator, an external mechanical variable attenuator, or an external electronic variable attenuator.Figure 3. Typical output power vs. mm-wave frequency for OML S10MS-AG.Excellent FM, PM and Pulse ModulationFM and/or PM may be applied to the SxxMS-AG series module input signal with the corresponding mm-wave output signal being modulated with an FM/PM deviation that is N times the input deviation (no change in the FM/PM rate) where N is the multiplier factor of the SxxMS-AG module.The pulse modulation characteristics of the input signal are reproduced faithfully, with the exception of pulse rise and fall times. The non-linear characteristics of the source module will typically produce an output signal pulse with faster rise and fall times. Faster rise and fall times will also yield a small increase in the width of the pulse.AM and Vector ModulationThe non-linear multiplication characteristics of the SxxMS-AG series do not allow replication of linear AM (sinusoidal amplitude modulation) or vector modulated signals. Easy connection and operationThe SxxMS-AG has been designed to work directly with the PSG source-module interface (SMI) power supply specifications. Once the SxxMS-AG module is connected to the PSG via the SMI cable and an RF cable (Figure 5), the PSG user interface can be configured to directly display the mm-wave output frequency.Connect the SxxMS-AG module per Figure 5. Then follow the PSG key steps shown in Figure 6 to select the appropriate mm-wave frequency band for the connected module. Once the OEM source module “ON” selection has been made, the frequency shownon the PSG will be the output frequency of the mm-wave source module. To change the output frequency of the source module, simply enter the desired mm-wave output frequency into the PSG, and the PSG will do the rest. The amplitude value shown on the PSG is the output power of the PSG, and it must be set to +16 dBm for optimum performance of the source module.Figure 4. Typical rise and fall time of the module output signal vs. thepulsed, input driving signal.Figure 5. Source module to PSG hardware connections.Figure 6.

True to the MusicUser GuideUSB-PRO USB Direct Box ™Radial Engineering Ltd.1845 Kingsway Ave., Port Coquitlam, BC V3C 1S9, Canadatel: 604-942-1001 • fax: 604-942-1010******************Radial USB-PRO USB to Audio Direct Box™®Table of Contents PageOverview (1)Features (2)Getting started and audio connections (3)Testing and Using (4)Eliminating hum and buzz (4)Using the headphone output (5)Specifications (5)Radial Limited Warranty ...................................Back CoverINTRODUCTION Congratulations on your purchase of the Radial USB-Pro!The Radial USB-Pro is a high-resolution stereo direct boxdesigned to convert sound files from a laptop computerand seamlessly transfer them to a pair of balanced audiooutputs to feed a PA, recording or broadcast mixingconsole.Plug and play easy to use, the USB-Pro can be up andrunning in no time. That said, as with any new product, werecommend that you take a little time to read through themanual in order to familiarize yourself with the USB-Profeatures so you can get the most out of it.If you have any questions that are not covered in thismanual, please consult the FAQ section on the web siteas this is where we post the latest updates and questionsfrom other users. If you still can’t find what you are lookingfor,********************************************we will do our very best to reply in short order.OVERVIEW The Radial USB-Pro is a plug and play, 24bit digital to analog audio converter and professional direct box in a compact and road rugged package.A typical direct box is a device that lets you interface a high impedance (hi-Z) audio output with professional low impedance (low-Z) PA and recording systems. In the case of the USB-Pro, the digital audio signal is controverted to analog and feeds directly into the direct box circuit to produce low-Z balanced left and right stereo signals. The built in preamp allows you to adjust the output level from mic-level to line-level and enables the USB-Pro to connect directly to mixing consoles, power amplifiers and self-powered speakers alike. The USB-Pro ensures thedigital signal is delivered to the PA as faithfully as possible.MAC or PC PA SYSTEMUSB-Pro The USB-Pro is very easy to setup and use because it derives power from the USB connection and automatically configures the sampling rate and bit depth without the need for special drivers. The USB-Pro can be used for audio playback, system testing and for transferring digital audio files to analog for processing.Following the block diagram below, a computer’s USB digital audio output is converted to analog audio. A level control allows you to adjust the output level and a mono sum switch can be activated to send mono signals to two separate audio systems or check for phase issues. The 3.5mm mini-headphone output can be used to monitor the stereo signal. Before the XLR output, isolation transformers may be switched into the circuit to eliminate noise caused by ground loops. The signal is then balanced to drive long cables without inducing noise. LAPTOPFEATURE SET1. LEVEL: Used to set the overall output level.2. MONO: Sums the stereo signal to mono. When active, the LEDindicator illuminates. Mono mode reduces the channel count on the PA or lets you send the signal to two separate audio systems simultaneously.3. HEADPHONE: Mini 3.5mm (1/8") TRS headphone output is used tocheck the output from the digital source for trouble shooting. Works with ear-buds and standard headphones.4. USB PORT : Connects from the PC or Mac using a TYPE B cable. Thisport delivers the digital audio signal and power to the USB-Pro which automatically recognizes the sample rate and bit depth.5. POWER LED: This indicator will illuminate when the power is receivedfrom the USB connection.6. LEFT XLR OUT : Standard XLR male output follows the AES formatwith pin-1 ground, pin-2 hot, pin-3 cold.7. GROUND LIFT : Used to help eliminate hum and buzz caused byground loops. Lifts pin-1 on both XLR outputs.8. RIGHT XLR OUT : Standard XLR male output follows the AES formatwith pin-1 ground, pin-2 hot, pin-3 cold.9. ISOLATION: Switches on side panel for each channel lets you inserttransformer isolation when needed. Use to eliminate hum and buzz caused by ground loops.GETTING STARTED Before making any connections, always ensure your audio system is either turned down or turned off in order to protect more sensitive components from damage due to loud turn-on or plug-in transients. USB CONNECTION As the USB-Pro uses a TYPE B USB connector, you will need a USB 2.0 cable that fits the USB port on your computer or laptop. This is a common ‘TYPE A to TYPE B’ USB cable that is compatible with the majorityof printers, hard drives and audio interfaces.TYPE A USB Fits most laptops and computers TYPE B USBUsed to connect to the USB-ProThe Radial USB-Pro is powered by your computer’s USB port. As soon as you plug it in the USB-Pro will power up. The POWER LED indicator will illuminate to let you know the USB-Prois up and running. On most computers theUSB-Pro will automatically become thedefault audio output device after it is pluggedin. If this does not happen automatically, goto your system settings/control panel andselect the ‘Radial USB Pro’ from the list ofavailable audio devices.AUDIO CONNECTIONS Connect two standard low-impedance XLR cables from the LEFT and RIGHT outputs to the mic or line inputs of your PA or recording system. These XLR outputs conform to the AES standard and are balanced to drive long cable runs up to 100 meters (300') without noise and are suitable to connect the USB-Pro to professional mixing consoles, preamps and power amplifiers.balanced XLR cables up to 100 meters (300').IMPORTANT NOTICE: The USB-Pro does not require phantom power to operate. For best results ensure the phantom power is switched off when connecting to the microphone input of a mixer. In case of use with a mixer with global phantom power that is activated, the isolation/bypass switches on the USB-Pro are to be set to the isolation position.LED Power IndicatorTESTING AND USING First, set the USB-Pro’s LEVEL control tothe 7 o’clock (off) position. This will allowyou to adjust the output level on the fly.Next, check the status of the MONO SUMswitch and LED indicator. For stereo, setthe switch to the outward position (LEDoff). For dual mono outputs, set the switchto the inward position (LED on). It’s a good idea to start testing your computer’s audio with a sound file you are familiar with. Set your computers output level and the level of the media playback software (if applicable) to approximately 80%. Keep in mind that various media files will play back at different volume levels depending on your software and how the sound file was recorded.Slowly raise the output level of the USB-Pro. It is good practice to always test at a low volume to ensure proper connections have been made and all devices in the signal chain are set up correctly and working. This way, should a device not be turned on or a connection not fully made, it will not create a loud transient ‘pop’ in the PA which could damage a tweeter or annoy your audience. When satisfied, slowly increase the input gain on your mixing console until you reach an appropriate level.In some cases, like when a second audio interface is also connected to your computer alongside the USB-Pro, your computer may not automatically switch to the USB-Pro as the main audio output. In such cases you will need to enter your computer system’s control panel and select the USB-Pro as the audio output device from a list of available devices.ELIMINATING HUM AND BUZZ The USB-Pro has been designed tominimize hum and buzz caused byground loops by incorporating dualisolation transformers for the XLRoutputs. The isolation transformersare normally bypassed but may beintroduced into the signal path using theside access ISO switches. If you hearnoise after connecting the USB-Pro toyour audio system, try engaging theisolation transformers by sliding theswitch in the direction of the arrow.This is supplemented with a ground LIFTswitch located next to the XLR outputs.When set to the inward position, this switchdisconnects pin-1 from the two XLR’s.Left & right transformer isolation switchesGround LiftUSING THE HEADPHONE OUTPUT The USB-Pro is also equipped with a stereoheadphone output. This headphone amplifieris controlled by the master output level control,and is designed to be used to check signalbefore plugging into a PA system. Adjusting thelevel control on the USB Pro will affect both theXLR and the headphone output. The 3.5mm(1/8") output is designed for both ear buds andstandard TRS stereo headphones where tip-left,ring-right and the sleeve is ground. Be Careful , the USB-Pro is designed for professional use as the headphone amp is very powerful and is capable of high sound levels when driven to maximum. Always ensure the output level of your computer, laptop or tablet is set at an appropriate level before auditioning music through headphones. This will not only save your ears, but save the ears of your client!

解密数字音乐，什么程度才是无损音质？
解密数字⾳乐，什么程度才是⽆损⾳质？在⽣活中很多⼈有这样的疑问，⽐如什么是⽆损⾳乐？mp3⽂件中的320kbps和128kbps是什么意思？如果再发烧⼀点，HiFi、Hi-Res、DSD到底⼜是什么？这些⾳乐格式是如何⼯作的？⼿机、电脑⾥的⾳乐能被播放出来的先决条件是，这段⾳乐（声⾳）能被存到⼿机和电脑⾥。
这听起来有点像废话，但是这会产⽣⼀个问题，那就是：对于声⾳这种我们只能听得见但抓不住的事物来说，如何把它存储到电脑⾥？电脑通过“⼆进制数字”存储信息，也就是电脑中的任何信息都是以“⼀串0和1的排列”（例如100101000110101）的形式存在的，是“0和1的序列”之不同导致了信息内容的不同。
举⼀个⽣活中的例⼦就更容易理解了：对于英语这门语⾔来说，信息能被表⽰成⼆⼗六个字母的形式，然后被存储在纸上，是“字母组合”之不同导致了信息内容的不同。
电脑只认识两个“字母”，即0和1，它⽤0和1存储信息。
⽐如字母“a”在电脑⾥⾯就被存储为了“01100001”。
那么问题就被转化为了：我们是如何将声⾳转化为“0和1的排列”呢？为了解决这个问题，⾸先我们需要看看“声⾳”的本质。
在初中物理中我们就已经学过，声⾳的本质不是我们⽿朵听到的那个“响”，⽽是在物体中“传播的振动”。
我们感知了这种振动，通过⼤脑把它转化为了听到的声⾳。
当时的物理⽼师⼤都给我们演⽰的是像⽔波纹⼀样传递振动的横波，如下图所⽰，粒⼦的振动⽅向（上下）和振动的传播⽅向（向右）垂直：但在空⽓中，声⾳其实是以纵波的形式传递振动的，就像下⾯的动图，其中每个⿊点是空⽓中的分⼦，分⼦的振动⽅向（左右）和振动的传播⽅向（向右）相同：以时间t为横轴，空⽓中某个位置的压强P为纵轴（密度ρ越⼤，压强P越⼤），声⾳就可以被描述成⼀种波形声⾳，可得到波形图如下：将压强值减去平均压强值（也就是⼤⽓压Patm）得到相对压强值，再以其为纵轴，以时间为横轴，可得到某点附近的，压强随时间的变化⽽变化的图（可以理解为⽿膜附近的相对压强随时间⽽变化的图），得到波形图如下所⽰：在波形图中，横轴描述了时间，纵轴描述了波形声⾳的振幅。

hi-res什么意思
hi-res什么意思我们经常会在一些音频类产品包装上看到Hi-Res AUDIO 金标，熟悉的朋友可能会知道，这是索尼首先提出的高品质音乐标准。
▌Hi-Res出现的背景首先我们要知道，DTS、Dolby、SRS 、WOW、BBE这些常见的音效标志都不是索尼的，而在产品上直接用各种音频格式和编码率标志（24bit/32bit）表示，也很不合适。
因此，索尼非常需要一个属于自己，又非常有识别度的新标识，来标识自己的产品，代表认证这款产品“声音很好”。
于是，Hi-Res Audio就此诞生了！▌什么是Hi-Res高解析音频？Hi-Res是High Resolution Audio的缩写，它是索尼在2014年提出的最新高品质音乐标准。
它的音质表现远远超过现有压缩音频格式、CD，音频格式的规格可高达192kHz / 24bit或者更高的解析度，也就是采样率高于44.1KHz，比特深度大于16bit。
（过去16bit/44.1kHz编码率统治了这个世界大半个世纪）▌如何界定Hi-Res高解析音频？虽然Hi-Res是由索尼率先提出，但为了确保一致性，消费技术协会（CTA）、数字娱乐集团（DEG）、录音工程方和各大唱片公司联手统一Hi-Res音频定义标准。
依据CTA的定义：“Hi-Res高解析音频是一种无损音频，它在录音上力求最大程度还原源声，其音质表现高于CD音频源。
”此外，4种主流的高品质录音类别用来描述Hi-Res音频出处：MQ-P（来源于PCM数字母带，规格不低于48 kHz/20-bit）、MQ-A（模拟母带）、MQ-C（从44.1 kHz/16-bit的CD 规格升频）、MQ-D（DSD母带）。
▌Hi-Res高解析音频能为我们带来什么？Hi-Res通过近乎毫无损失地数字化捕捉原始模拟音频源，从而详实但还原各种声音。
像CD这类传统音频，录制的时候删除了声音但一部分，只保证了必要部分，而不是全部但声音。
高解析度音频则包含了声音的许多信息量，例如"声音的厚度、细腻度、深度、声压级"等，包含的声音信息量约为CD的6.5倍。

Talented college players can be picked by national teams and become professional players.So for some young athletes,playing sports after school can lead to a full-time career.31．What is known as the“national pastime”of the US?A．Playing baseball.B．Playing soccer.C．Playing basketball.D．Playing football.32．Which of the following is TRUE about American football?A．It is only played in America.B．It is more popular in Europe.C．It is similar to rugby in Britain.D．It is unknown to people in Asia.33．How can your team score points in American football?A．Kick the ball into the“end zone.”B．Pass a wall of defending players.C．Throw the ball to a player in the“end zone.”D．Receive the ball and run down the field.34．Why do college students in the US take sports seriously?A．Because they can earn money from playing on national teams.B．Because they can have fun when they’re not busy with school.C．Because they can make friends with high school players.D．Because they can be picked to play on national teams.（二）Tomb Sweeping Day is a one-day Chinese holiday that has been celebrated in China for centuries.Every year in early April,tens of thousands of people in China visit the tombs of their ancestors to show their respect.On the day,Chinese families will sweep the tombs and clean away the grass around them.Then they burn paper money and put flowers and fruit in front of the tombs.They hope the dead can enjoy them and bring the family good luck.However,it is not only the Chinese who remember the dead.People in other countries also have festivals for the dead.In Japan,O-Bon Festival is one of the most important festivals.It is held from August13to16.It is also a holiday that serves as a family reunion(团圆).During O-bon,Japanese people return to their hometown and visit their ancestors’tombs.They also believe their ancestors’spirits return home to be reunited with their family. People perform a“bon odori”dance to welcome the spirits.On the last day of O-bon,they put paper lanterns in a river to send off the spirits.In Russia,people remember their ancestors on the Day of Rejoicing(欣慰).It’s usually in late April or early May.The name of this festival means birth and happiness.Russians believe that people shouldn’t feel sad for the dead because death means birth in another world.On the Day of Rejoicing,Russian people draw beautiful pictures on eggs and put them in front of tombs.After that they have a picnic together.They hope for a good life for both the living and the dead.35．What do we know about Tomb Sweeping Day?A．It falls on April4every year.B．It’s a day to remember the dead.C．People grow grass beside the tombs on that day.D．It’s said that people can see the dead on that day.36．In which country people may remember the dead on April6?A．China.B．Japan.C．Russia.D．Korea.37．We know the following about O-Bon Festival EXCEPT that________.A．it is a Japanese festival B．it lasts four days in AugustC．it’s also a family reunion day D．paper lanterns are used to welcome the spirits 38．What do Russian people think of death?A．It’s a sad thing.B．They feel happy about it.C．It means birth in another world.D．It means a good life for the dead.39．What does the story mainly talk about?A．History of Tomb Sweeping Day.B．How to remember the dead.C．Meanings of death in different countries.D．Festivals in some countries to remember the dead.四、阅读下面的短文，用括号内所给词的适当形式填空，必要时可加助动词或情态动词。

ADon’t like getting out of the shower on cold mornings? Are you feeling that cold wind when working or trying to relax?The biggest issue that people have is the fact that most old-fashioned heaters are big, cost a lot to run and waste energy. Luckily, a company has recently just developed a product which saves a ton of power during its operation and is, above all, smart and easy to use! It’s called HotixPro and it’s a very small, powerful heater that consumes much less energy than regular heaters.How Does HotixPro Work?The ceramic element (陶瓷零件) stays warm 30% longer, so it doesn’t have to use much power to reheat over and over again. The fan inside HotixPro then sucks the air out through the hot ceramic element and distributes it evenly throughout the room! It can heat a room up to 250 square feet and make it warmer in a few minutes, for just pennies.What Makes It So Special?One of the amazing features it has is the programmable timer. You can program it and warm up your bathroom before you wake up. Also, its remote controller makes it very easy to adjust the temperature. The company also kept safety in mind in the creation process——they added a sensor which makes HotixPro stop completely if it becomes too hot.Is It Worth It?Don’t let your quality of life continue to suffer. Save on expensive energy costs and keep warm during the winter anywhere! Purchase HotixPro at half price with free worldwide shipping!1．What is the main advantage of HotixPro?A．It is delicate. B．It is efficient. C．It is big. D．It is free of charge.2．How does HotixPro make a room warm?A．By keeping a high temperature itself.B．By storing the heat inside its big body.C．By heating the ceramic element again and again.D．By taking in cold air and giving off warm air.3．What is a programmable timer used for?A．Checking the temperature automatically.B．Adjusting the temperature from a distance.C．Turning on or off HotixPro at the set time.D．Turning off HotixPro when the room is too hot.BThe Andler Hillclimb is an annual dirt bike competition that has dirt bikers from around Europe try, to reach the top of a dangerous hillside course in Belgium. It’s been held every year for th e last two decades, but so far, no one has been able to reach the top.The so-called “impossible climb” starts out as rough gravel and then switches over to a rough uneven cliff (悬崖) face designed to throw riders off and roll them and their bikes back down to the base of the hill. It’s not the angle of the course that is the problem, according to most riders, but the sudden change of ride surface that makes keeping control of the bike and reaching the top so hard. Some fly off their bike early during the climb. While others get painfully close to the finish line, yet in the end they all succumb to the power of gravity (重力) before reaching their goal.Despite gathering the most talented dirt bikers in Europe at the start line every year, the Andler Hillclimb has so far remained unconquered. The closest one to success was a Suzuki bike rider who once reportedly crossed the finish line with the front wheel before rolling back down the slope like the rest of the competitors. Sadly, his achievement didn’t count as a valid climb, as the entire bike and its rider must make it to the top of the hill.With so many riders having failed to conquer the Andler Hillclimb over the last 20 years, why are people still trying every year? Why not just call the climb impossible and stop it? Well, maybe it has something to do with the bragging rights (胜者为王)? Can you imagine what it would be like to be the very first dirt biker to reach the top of this famous hill?In case you want to try your luck, or if you simply want to see the hill make fools of dozens of daredevils (蛮干者), this year’s event is scheduled for August.4．What makes it difficult for bikers to reach the top of the Andler Hillclimb?A．The bikers’ poor riding skills.B．The steep angle of the slope.C．The rough gravel road surface. D．The sudden changes in ride surface.5．What do the underlined words “succumb to’’ in the second paragraph probably mean?A．Give in to. B．Break through.C．Learn about. D．Fight against.6．Why does the author mention the example in the third paragraph?A．To criticize the strict rules of the competition.B．To express regret over the Suzuki bike rider’s failure.C．To show how difficult it is to win the competition.D．To explain why the competition is popular with bikers.7．What do we know about the Andler Hillclimb from the passage?A．It is the most dangerous European competition.B．It is expected to be held in August this year.C．It is attended by the world’s best dirt bikers every year.D．It aims to throw riders and their bikes back down the hill.CAlthough we live in an era where everything seems to be available immediately, our study suggests that today’s kids can delay gratification(满足感) longer than children in the 1960s and 1980s,“ said University of Minnesota psychologist Stephanie M. Carl son.” This finding stands in great contrast with the assumption by adults that today’s children have less self-control than previous generations.The original marshmallow(棉花糖) test conducted by researchers at Stanford University involved a series of experiments in which children aged between 3 and 5 years were offered one treat that they could eat immediately or a larger treat if they waited. Researchers then left the room to see how long the children would wait and watched from behind a one-way mirror.Interestingly, today's adults thought that children nowadays would be more impulsive and less able to wait, Carlson found. "Our findings serve as an example of how our beliefs can be wrong and how it's important to do research,” saidco-author Yuichi Shoda, PhD at the University of Washington.The researchers offered several possible explanations for why children in the 2000s waited longer than those in prior decades. They noted a statistically significant increase in IQ scores in the last several decades. Another explanation may be society's increased focus on the importance of early education, according to Carlson. The primary objective of preschool changed from largely custodial care (监护) to school readiness in the 1980s. Parenting also has changed in ways that help promote the development of executive function, such as being more supportive of children's self-control, the researchers noted.Walter Mischel of Columbia University, who co-authored this paper, noted that “while the results indicate that thechil dren’s ability to delay is not weakened on the marshmallow test, the findings do not speak to their willingness to delay gratification when faced with the many temptations now available in everyday life.”8．According to the passage, what is the adults' assumption about today's children?A．They are not easy to please.B．They are less able to control themselves.C．They don't like things that are easy to get.D．They have different personalities from previous generations.9．What does the underlined word "impulsive " in Paragraph 3 mean?A．productive B．considerateC．clear-minded D．hot-headed10．What did the researchers find about children in the 2000s?A．They are more prepared to go to school.B．They are not as clever as previous generations.C．They are taught self-control only by their teachers.D．They don’t need any custodial care in their early childhood.11．What does the author want to tell readers in the last paragraph?A．Most children nowadays can't resist the temptations of everyday life.B．Children chose to delay gratification willingly in the marshmallow test.C．The test can’t accurately measure children's willingness to delay gratification.D．Children’s ability to delay gratification is weakened because there are many temptations.DImagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag. The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple.This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even unde r your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP section and pays for the bill with the wave of an arm.Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler.RFID tags are a sma ll part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr. J. Reich. Human right supporters are nervous about the possibilities of suchtechnology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits.When Marconi invented radio, he thought it would be used for ship-to-shore com munication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.12．The article is intended to.A．warn people of the possible risks in adopting RFID technologyB．explain the benefits brought about by RFID technologyC．convince people of the uses of RFID technologyD．predict the applications of RFID technology13．We know from the passage that with the help of RFID tags, people.A．will have no trouble getting data about othersB．will have more energy for conversationC．will have more time to make friendsD．won’t feel shy at parties any longer14．Why are some people worried about RFID technology?A．Because children will be tracked by strangers.B．Because market competition will become more fierce.C．Because their private lives will be greatly affected.D．Because customers will be forced to buy more products.15．The last paragraph implies that RFID technology.A．will not be used for such matters as buying milkB．will be widely used, including for buying milkC．will only be used for buying milkD．will probably not be widely used第二节（共5小题；每小题2分，满分10分）We all know about the health benefits of swimming. It offers a great workout to the body — it builds endurance, muscle strength and cardiovascular (心血管的) fitness. ____16____ Many people feel that swimming is very exciting and relaxing.Cold-water swimming — sometimes called wild swimming — involves swimming in natural areas including ponds, rivers and the sea. Jumping in cold water gives a short sharp shock to the body. ____17____ A cold dip might wake you up, but research has found it can have much bigger benefits than those for your body and mind. As well as being good exercise, cold-water swimming improves well-being.____18____ One man who suffered constant pain after surgery claimed he was cured by taking a swim in cold open water. And another swimmer, Sandri a Simons, told the BBC “the immersion of your body in cold, salt water, just feeling like you’re at one with nature if you like, just feels amazing.”What is it that people are gaining from this cold experience? Doctors say getting into cold water makes a stress response, but the more you do it, your reaction to stress is reduced. ____19____ In addition, cold-water swimming can exercise swimmers’ willpower. But there are bigger benefits of this stress-reducing exercise. Some experts believecold-water swimm ing helps “cross-adaptation”, where one form of stress prepares the body for another.____20____ So, if you’re convinced that this is for you, take advice: approach it with caution, swim with a friend, and maybe start in summer, when the water temperatures are higher.A．Cold-water swimming is beneficial to people.B．If you don’t mind getting wet, it can be fun, too.C．However, many participants sat they get used to it.D．It’s also thought to strengthen our digestive function.E．We all know exercise can make people live a long life.F．Cold-water swimming can cure certain conditions.G．For example, it helps reduce the stress of exercising at high altitudes.第二部分语言知识运用（共两节，满分45分）第一节（共20小题，每小题分，满分30分）阅读下面短文，从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。

A40-YEAR HIGH-RESOLUTION WIND AND W A VE HINDCAST FOR THESOUTHERN NORTH SEARalf Weisse,Heinz G¨unther,and Frauke FeserGKSS Research CenterInstitute for Coastal ResearchGeesthacht,Germany1.INTRODUCTIONThe planing of sustainable development and of economic activities in the marine environment requires long term information about the prevailing environmental conditions.For the design of marine and coastal protec-tion structures detailed knowledge on local wave conditions is an essential prerequisite.To estimate the risk which emerges from local wave conditions knowledge on both,the wave climatology and the extreme events is necessary.Direct observations of sufficient length are not always available at the place of interest.Furthermore,observa-tions are usually distributed irregularly in space and time.Therefore,there have been a number of studies in the recent past that tried to use numerical wave models to provide hindcasts of the past wave conditions.For example,one of the more prominent attempts to reconstruct the wave and storm climate over a longer period was provided by the W ASA Group(W ASA1998).The objective here was to prove or disprove hypotheses of a worsening storm and wave climate in the Northeast North Atlantic.The changes in the wave climate were assessed using a state-of-the-art wave model driven by wind analyses over a period of40years(1955-1994) (G¨u nther et al.1998).The W ASA data set has proven to be extremely useful and was requested frequently,often being the only source of information available for wave climate studies at many places along the European Coast.However,there was increasing awareness that the spatial and temporal resolution of this data set was too coarse for many ap-plications,especially in coastal areas and that the atmospheric forcing suffered from a lack of inhomogeneities along the reconstruction period(G¨u nther et al.1998).Therefore,based on the experience made within the W ASA,the European project HIPOCAS(Hindcast of Dynamic Processes of the Ocean and Coastal Areas of Europe)(Soares et al.2002)was set-up to reduce several of these shortcomings,in particular to use more homogeneous windfields and to increase the spatial and temporal resolution of the wave hindcast.Although HIPOCAS is focused on providing high-resolution wind,wave and storm surge hindcasts as well as climatologies for a variety of European Coastal Areas we here concentrate on the results obtained for the Southern North Sea so far.For a more detailed overview on the coastal areas studied under the HIPOCAS project we refer to Soares et al.(2002).In section2we briefly describe the methodology and the models applied for the Southern North Sea.Preliminary results are presented in section3.A summary and preliminary conclusions are provided in section4.2.METHODS AND GENERAL APPROACHOne objective of HIPOCAS is to provide a reasonable reconstruction of the wave conditions and the wave climate over the past decades for the European Coastal Areas.For the Southern North Sea we therefore have adopted the following approach:2.1Atmospheric forcingThe windfields provided by the40-year RAM integration(section.2.1)have been used in cooperation with the Coastal Division of the Federal Waterways Engineering and Research Institute(BAW)to drive a storm-surge model for the North Sea.The objective of this simulations was twofold:First,we were interested in a comprehensive and consistent wind,wave and surge data set for the Southern North Sea.Second,we expected an impact of the water level variations caused by tides and surges on the modeled wave heights because of the relative shallow water depths in the Southern North Sea.The magnitude of this effect is illustrated in Figure1 for the platform K13-Alpha where the water depth is about27m.Here the effect was found to be in the order of1-3%of the modeled wave height.It increases with decreasing water depth.The simulations of the tides and storm surges in the North Sea have been performed at the BAW using their finite element high-resolution hydrodynamical model TELEMAC2D.This model is used routinely by some German coastal authorities and has a resolution of a few kilometers in the Northern North Sea which increases towards the German Bight were itfinally reaches a few hundred meters.The model domain comprises the entire North Sea.External surges have been taken into account by assimilating water level observations at Ab-Figure1:Difference in simulated significant wave height in cm between two wave model simulations(bottom).In thefirst simulation (FP2)time dependent water levels caused by tides and surges have been accounted for while in the second simulation(FP1)a constant water depth was used.Results are shown at platform K13-Alpha(53.22N,3.22E).For comparison modeled(solid)and observed(crosses) wave heights are shown additionally(top).erdeen.The simulation has recently been completed and data are analyzed right now.Initial analysis showed that reasonable reconstructions of the water levels along the German coast have been obtained this way(Pluess m.2002).2.3Wave ModelingFigure2:Monthly bias(a),root-mean-square error(b),magnitude(c)and veering angle(d)of the complex correlation between the observed and the modeled wind at Ocean Weather Ship Mike for the period1958-1991.We used the complex correlation(Kundu1976)between the observed and the modeled windfield to assess the quality of the numerical wind hindcast,and the indices“obs”and“mod”denote the winds taken from observation or simulation.denotes the expectation operator,the complex conjugate,is defined as and is defined similarly.The correlationcan be written in polar coordinates as(2) where the length represents a measure of the overall magnitude of the correlation and the phase angle is a measure of the average relative angular displacement(veering)between a pair of two dimensional vector timeFigure3:Simulated and observed annual wind speed quantiles(top,in ms)at the platform K13-Alpha in the Southern North Sea, and annual root-mean-square errors of wind speed(bottom panel,in ms).In the upper panel,the annual99%,95%,90%and50% percentiles(from top to bottom)are given,with the solid line representing the simulations and the dashed line the observed data. series(cf.Kundu1976).Monthly complex correlations between the observed and the modeled winds at10m height at Ocean Weather Ship Mike(66.0N,2.0E)are shown in Figure2.In general the complex correlations indicate a good agree-ment between the observations and the simulation.For the entire period from1958until1991the magnitude of the complex correlation is in the order of0.8.The relative angular displacement between the observations and the simulations is about10to15throughout the simulation period with slightly smaller variability at the end of the simulation.Additionally,monthly biases and root-mean-square errors are shown in Figure2.It can be obtained that on average the simulation underestimates the observations by1ms or so.However,the bias is rather sensitive on how the observations have been reduced to10m height.The monthly root-mean-square error is in the order of3to4ms with a slight tendency towards smaller values at the end of the simulation period.Figure3shows observed and modeled annual wind speed percentiles at K13-Alpha together with the annual root-mean-square error.After about1985there is a very good agreement between the observed and the mod-eled percentiles even for the very high percentiles.The root-mean-square error is about3.3ms in1982and decreases strongly until1985.It then remains at about2.5ms for the rest of the simulation period.Figure4:Simulated and observed annual wave height quantiles(top,in m)at the platform K13-Alpha in the Southern North Sea,and annual root-mean-square errors of wave height(bottom panel,in m).In the upper panel,the annual99%,95%,90%and50%percentiles (from top to bottom)are given,with the solid line representing the simulations and the dashed line the observed data.A similar analysis for the wave height at K13-Alpha is presented in Figure4.For the50%percentile again a very good agreement with the observations can be inferred.For the highest percentiles,however,an overes-timation between about10and40cm can be inferred.This is illustrated also by the root-mean-square error which is in the order of about45to50cm for the entire period for which observational data have been avail-able.Contrary to the wind speed,the root-mean-square error for the wave height shows no significant decrease between1982and1985as it was obtained for wind speed(Figure3).We therefore conclude that the large differences between modeled and observed wind speed in this period are more likely caused by observational problems at the beginning of the recording period than by atmosphere model errors.Table1shows some statistics for wind speed and wave height for three different buoys and platforms for the period1985until1997.For wind speed a reasonable agreement can be obtained.The statistics at Huibertgat are slightly worse than those for K13and Europlatform since model winds at Schiermonnikoog have been com-pared with measurements at Huibertgat.For the wave heights the agreement is best for K13and Europlatform and noticeably worse for Schiermonnikoog.The reasons for this are not yet clear and are presently investigated.Table1:Observed and simulated mean together with bias,root-mean-square error and correlation between observed and simulated data for wind speed and wave height from the
