一、选择题(每小题4分,共60分;1-9小题有一个选项是正确的,10—15小题至少有一个选项是正确的)1.关于磁通量的概念,下面说法正确的是( )A .磁感应强度越大的地方,穿过线圈的磁通量也越大B .磁感应强度大的地方,线圈面积越大,则穿过线圈的磁通量也越大C .磁通量的变化,不一定由于磁场的变化产生的D .穿过线圈的磁通量为零时,磁通量的变化率一定为零【答案】C考点:磁通量【名师点睛】此题是对磁通量及磁通量变化率的考查;要知道磁通量与三个因素有关,大小为cos BS αΦ=;磁通量的变化可能由磁场的变化引起,也可能是由线圈的有效面积变化引起的,磁通量为零,但是磁通量的变化率不一定为零.2.下列关于电磁感应的说法中正确的是( )A .只要闭合导体与磁场发生相对运动,闭合导体内就一定产生感应电流B .只要导体在磁场中做相对运动,导体两端就一定会产生电势差C .感应电动势的大小跟穿过回路的磁通量成正比D .闭合回路中感应电动势的大小只与磁通量的变化情况有关而与回路的导体材料无关【答案】D【解析】试题分析:当闭合导体与磁场发生相对运动,若磁通量不变,则不会产生感应电动势,因此也没有感应电流,故A 错;如果导线在磁场中沿着磁感线的方向运动,不切割磁感线,不会产生感应电动势,故B 错;法拉第电磁感应定律中,感应电动势的大小与磁通量的变化率及线圈的匝数成正比,故C错;闭合回路中感应电动势的大小只与磁通量的变化情况有关,而感应电流的大小与回路的导体材料无关,故D正确.故选D.考点:法拉第电磁感应定律。

【名师点睛】电磁感应现象的学习重在理解两点:①产生感应电流的条件:闭合、部分、切割,即为磁通量变化;②电磁感应现象中感应电动势的大小与磁通量的变化率成正比。

3.关于对楞次定律的理解,下面说法中正确的是()A.感应电流的磁场方向,总是跟原磁场方向相同B.感应电流的磁场方向,总是跟原磁砀方向相反C.感应电流的磁场方向可以跟原磁场方向相同,也可以相反D.感应电流的方向总是要使它的磁场阻碍原来的磁通量【答案】C考点:楞次定律【名师点睛】此题是考查对楞次定律的理解;根据楞次定律知,感应电流的磁场总是阻碍引起感应电流的磁通量的变化.当穿过线圈的磁通量增大时,感应电流的磁场与它相反,当磁通量减小时,感应电流的磁场与它相同。

Before you dismiss it as a habit suited only for young kids, consider that there are serious advantages in being well-rested. And now, even more research suggests that putting phones away before going to sleep is important to teens‟ well -being.A new study from Seton Hall University School of Health and Medicine Science found that 62 percent of kids used their smart phones before bed, and it‟s causing less sleep and poor performance in school.Those teens who text(发短信) before bedtime tend to go to sleep later, and get up later in the morning. Such behavior can be associated with mental health issues like depression or anxiety. Besides, once teens do receive a text, experts found, they tend to respond right away. Then the text conversation continues — resulting in an even later bedtime.The study‟s co -author Dr. Peter Polos says this leads to excessive stimulation(过度刺激) at night. Light from electronic devices can block the secretion(分泌) of melatonin — a试卷第2页,共12页hormone(荷尔蒙) that promotes sleep, which makes sleep difficult in the face of overuse of smart phones at night. It‟s true! More screen time means less sleep time; other studies have suggested the same idea.As for a final piece of advice, Dr. Sushanth Bhat says, since getting the proper amount of sleep is very important for brain development and learning in the teenage years, our study should encourage parents and guardians (监护人) to limit adolescent smart phone usage at night. Keep in mind that teens aren‟t the only ones addicted to their phones! Adults can also benefit from setting a tech curfew(宵禁) for themselves. After all, kids learn by example! 1、What is the text mainly about? A .How to promote sleep.B .How kids learn from their parents.C .The advantages of going to bed early.D .The disadvantages of phone usage before bed. 2、Who are likely to go to sleep later according to the text? A .Kids having text conversations before bed. B .Kids putting their phones away at night. C .Kids studying their lessons hard at school. D .Kids exercising with friends after school. 3、Melatonin can ________.A .make sleep difficultB .lead to later bedtimesC .help people fall asleepD .wake people from a sleep 4、The author advises parents to ________. A .learn from their kids B .get rid of smart phones C .set a good example to their kids D .try to benefit from hi-tech developmentHumans have long been interested greatly in the idea of being able to walk on water. Sadly, biological facts prevent us ever realizing this dream without artificial aid —we simply weigh too much, and all our weight pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.However, several types of animals can walk on water. One of the most interesting is thecommon basilisk Basilicus basilicus, a lizard (蜥蜴) native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will reach a speed of 20 steps per second to keep moving forward. For humans, we would need huge feet that we could bring up to our ears in order to crea te enough “hitting”.But fortunately there is an alternative: cornflour(玉米淀粉). By adding enough of this common thickening agent to water (and it does take a lot), you can create a special mixture that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(微粒) in the water get together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of this adequately thick liquid of cornflour.Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings(救生圈) ready in case you start to sink—and take a bath afterward!5、Walking on water hasn't become a reality mainly because humans _________.A.are not interested in itB.are afraid to make an attemptC.have not invented proper toolsD.have biological limitations6、What do we know about Basilicus basilicus from the passage?A.It is light enough to walk on water.B.It can run across water at a certain speed.C.Its huge feet make it able to stay above water.D.Its unique skin keeps it from getting wet in water.7、What is the function of the cornflour according to the passage?A.To help the liquid behave normally.B.To turn the water into solid.C.To create a thick liquid.D.To make the water move rapidly.8、What is the author‟s attitude toward the idea of humans‟ walking on water?A.It is risky but beneficial.B.It is impractical though possible in thoery.试卷第4页,共12页C .It is crazy and cannot become a reality.D .It is interesting and worth trying.The USAWell, imagine how my sister felt when she went off for the first time to New York for a business trip. After a few days she was still amazed at how friendly everyone was to her until she took a taxi back to her hotel one night. First she gave just the name of the hotel, but when asked she said the address too. Then she was asked how to get there, but of course she didn‟t know. Imagine how frightened she was when the driver started shouting at her for not knowing the way. The UKA friend was in London for a conference. He took a taxi and there were no problems: the driver knew the way and was very cheerful. The problem started when he realized he had stupidly left his laptop on the back seat! He called the company up and, in a panic, went straightaway to their Lost and Found office. He was over the moon to find the laptop waiting for him, and then very surprised that it was one of 2,900 left in taxis over the past six months! TunisiaWell, my brother took a Mediterranean cruise(巡游) one summer and had a day in Tunis. He spent most of the afternoon in the Medina buying presents when he suddenly realized he‟d completely lost track of time and there was only half an hour before the ship left the port. There had been loads of yellow taxis in the centre so he wasn‟t too bothered until he stood on the pavement and waited for one to appear ——and of course there wasn‟t a single one in sight! Nothing! He questioned a passer-by who explained that the cost for the taxi ride goes up in the evening so the taxi drivers disappear until they can charge higher prices! Luckily for my brother the man then offered to give him a lift and he caught the boat on time! 9、What was the author‟s sister‟s trip by taxi in the US like?A .Unpleasing and scary.B .Tiring but impressive.C .Relaxing and exciting.D .Interesting but strange 10、T he underlined part “over the moon” in Paragraph 2 can best be replaced by “________”. A .very happy B .extremely sad C .quite surprised D .pretty annoyed 11、Why couldn‟t the author‟s brother find a taxi in Tunis?A.Because it was too late.B.Because the weather was bad.C.Because he didn‟t know how to call a taxi.D.Because the taxi drivers disappeared on purpose.12、What do the three stories have in common?A.They are all about taking a taxi.B.They are all about business trips.C.They are all about great services.D.They are all about the author‟s family.Cambridge University Botanic GardenWe run a lively programme of family events, life-long learning courses and much more throughout the year.Improve your Digital PhotographyThis course led by award-winning photographer, Pete Murray, will show you how to take control of your camera.

At that time, silk production was becoming weaker due to the slow collection process. To revive(振兴)the business, in 1947, he took a variety of silk clothes back to New York City to see if the product would be marketable to foreign consumers. He received a positive response, so the Jim Thompson Silk Company was founded in 1948.After the establishment of his company, silk costumes soon appeared in Broadway plays and popular films such as Ben Hur, and Thai royalty, such as Her Majesty Queen Sirikit, began wearing silk often.Many also thinkhis work contributed greatly to the Thai economy, since the silk industry continues to employ thousands of Thai citizens even today.Jim Thompson’s success is no mystery.However, his disappearance on March 26, 1967 certainly is one.Thompson made a trip to Malaysia to visit friends and one day , ventured into the jungle (丛林) on an afternoon walk.He was never seen again despite search parties sent out by the Royal Army Air Corps and British troops.Many have their own theories on his disappearance, but none have been completely confirmed.25.
