2020职称英语考试《理工类》A级完形填空专项模拟题(2)The central problem of economics is to satisfy thepeople's and nation's wants.The problem we are faced with is that our resources, here identified as money, are __1__. The only way we can resolveour problem is to make choices. After looking at our resources, we must examine our list of __2__ and identify the things we need immediately, those we can postpone, and __3__ we cannot afford. As individuals, we face the central problem involved in economics-deciding just how to allocate ourlimited our limited resources to provide __4__ with the greatest satisfaction of our wants.Nations face the same problem. As a country's population___5__, the need for more goods and services grows correspondingly. Resources necessary to production may increase, but there __6__ are enough resources to satisfy the total desires of a nation. Whether the budget meeting istaking place in the family living room, in the conferenceroom of the corporation __7__ of directors, or in the chamber of the House of Representatives in Washington, the basic problem still exists. We need to find __8__ of allocating limited resources in order to satisfy unlimited wants.A short time ago economists divided goods into two categories, free and economic. The former, like air and water, were in __9__ abundance that economists had no concern for them. After all, economics is the __10__ of scarcity and whatto do about it. Today many of these "free goods" are __11__ very expensive to use. Pollution has made clean air and water expensive for producers' extra costs, and __12__ taxpayers who pay for the government's involvement in cleaning the environment.In the 1990s, almost all goods are __13__. Only by effort and money __14__ obtained in the form people wish.Meeting needs of people and the demands from resource available __15__ the basic activity of production. In trying to meet unlimited wants from limited economic goods, production leads to new problems in economics.EXERCISE：1. A) limited B) unlimited C) scarcity D) abundant2.

“Liquefaction” Key to Much of Japanese Earthquake DamageThe massive subduction zone earthquake in Japan caused a significant level of soil “liquefaction” that has surprised researchers with its 51 severity, a new analysis shows.“We’ve seen localized examples of soil liquefaction as extreme as this before, but the distance and 52 of damage in Japan were unusually severe,” said Scott Ashford, a professor of geotechnical engineering at Oregon State University. “Entire structures were tilted and sinking into the sediments,” Ashford said. “The shifts in soil des troyed water, drain and gas pipelines, crippling the utilities and infrastructure these communities need to 53 . We saw some places that sank as much as four feet.”Some degree of soil liquefaction is common in almost any major earthquake. It’s a phenome non in which soils soaked with water, particularly recent sediments or sand, can lose much of their 54 and flow during an earthquake. This can allow structures to shift or sink or 55 .But most earthquakes are much 56 than the recent event in Japan, Ashford said. The length of the Japanese earthquake, as much as five minutes, may force researchers to reconsider the extent of liquefaction damage possibly occurring in situations such as this.“With such a long-lasting earthquake, we saw 57 structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes,” he said. “And it was clear that younger sediments, and especially areas built on 58 filled ground, are much more vulnerable.”The data provided by analyzing the Japanese earthquake, researchers said, should make it possible to improve the understanding of this soil 59 and better prepare for it in the future. Ashford said it was critical for the team to collect the information quickly, 60 damage was removed in the recovery efforts.“There’s no doubt that we’ll learn things from what happened in Japan that will help us to reduce risks in other similar 61 ,” Ashford said. “Future construction in some places may make more use of techniques known to reduce liquefaction, such as better compaction to make soils dense, or use of reinforcing stone columns.”Ashford pointed out that northern California have younger soils vulnerable to liquefaction-on the coast, near river deposits or in areas with filled ground. The “young” sediments, in geologic terms, may be those 62 within the past 10, 000 years or more. In Oregon, for instance, that describes much of downtown Portland, the Portland International Airport and other cities.Anything 63 a river and old flood plains is a suspect, and the Oregon Department of Transportation has already concluded that 1, 100 bridges in the state are at risk from an earthquake. Fewer than 15 percent of them have beenreinforced to 64 collapse.

职称英语考试《理工类》模拟试题及答案0509-23
职称英语考试《理工类》模拟试题及答案0509-231、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, and the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds and storm surges(风暴潮). The storm surges and heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, or the Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia and in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding and huge waves crashing on to the shore. During a hurricane, homes, businesses and public buildings may be damaged or destroyed, roads and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harbor if they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.Paragraph 4 ______【单选题】A.Where do hurricanes usually happen?B.What damages can a hurricane cause?C.What should you do during a hurricane?D.What is a hurricane?E.What are different names of hurricanes?F.How do you know a hurricane is coming?正确答案:C答案解析:本题难度不大，段落主旨句比较明显，在文章第四段的第一句：If a hurricane is coming in your area, the most important thing is to stay calm and find shelter immediately.回来看选项，C项简单概括了第一段的主要意思，是答案。

She and colleague Margaret Wallace ofthe City University of NewYork analyzed the flip-open phones(翻盖手机)of10 volunteers. They used swabs (药签) tocollect_____invisible___ (59) traces of the users from two parts of the phone：the outside, where the user ____holds_____(60) it, and the speaker which isplaced at the user's earThe scientists cleaned the phones using asolution made mostly__of____(61) alcohol. The aim of washing was to remove alldetectable traces of DNA. The owners got their phones backfor another week.Then the researchers ___returned________ (62) the phones and cleaned each phoneonce more.The scientists discovered DNA that _____belonged______(63) to the phone's speaker on each of the phones. Better samples werecollected from the outside of each phone, but those swabs also picked up DNAthat belonged to other people who had apparently also ____handed______ (64) thephoneSurprisingly, DNA showed up even in swabsthat were taken immediately after the phones were scrubbed. That suggests thatwashing won't remove all traces of ___evidence________ (65) from a criminal'sdevice.
