【題目】“Mobile phones killed our man.” screamed one headline last year. Also came statements that an unpublished study had found that mobile phones cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones heat the brain. For anyone who uses a mobile phone, these are worring times. But speak to the scientists whose work is the focus of these scared and you will hear a different story.

What we do have, however, are some results suggesting that mobile phones’ emission(輻射) have a variety of strange effects on living tissue that can’t be explained by the general radiation biology. And it’s only when the questions raised by these experiments are answered that we’ll be able to say for sure what mobile phones might be doing to the brain.

One of the strange effects comes from the now famous “memory loss” study. Alan Preece and his colleagues at the University of Bristol placed a devic(裝置) that copied the microwave emission of mobile phones to the left ear of volunteers. The volunteers were all good at recalling words and pictures they had been shown on a computer screen. Preece says he still can’t comment on the effects of using a mobile phone for years on end. But he rules out the suggesting that mobile phones have an immediate effect on our cognitive(感知的) abilities. “I’m pretty sure there is no short-term memory.” he says.

Another expert, Tatterasll, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses(神經(jīng)元突觸) exposed to microwaves become more—rather than less—receptive to under-going changes linked to the memory formation.

It would be an even happier outcome if microwave turned out to be good for you. It sounds crazy, but a couple of years ago a team led by Willian Adey at the Veterans Affairs Medical Center in California found that mice exposed to microwave for two hours a day were less likely to develop brain tumours(腫瘤) when given a cancer-causing chemical.

So should we forget about mobile phone radiation causing brain tumours and making us unable to think clearly or reasonably?

“If it doesn’t cause cancer in animals and cells, then it probably isn’t going to cause cancer in humans,” says William. And while there’s still no absolute evidence that mobile phone does damage your memories or give your cancer, the unanimity is: Don’t panic.

【1】What worries people who use mobile phones?

A. Mobile phones will kill them.

B. Mobile phones cause memory loss.

C. Mobile phones heat the brain.

D. All above is right.

【2】What is the attitude of Prece on the suggestion that mobile phones have an immediate effect on our congnitive abilities?

A. Doubt.B. Disagree.C. Approve. D. Wait and see.

【3】The underlined word “unanimity ”in the last paragraph most probably means “_______”.

A. consensusB. disagreementC. possibilityD. impossibility

【4】From the fifth paragraph, we can infer that being exposed to microwaves for two hours _________.

A. can result in killing you

B. is likely develop brain tumours

C. is unlikely to develop brain tumours

D. will cause your loss of memory for ever

【答案】

【1】D

【2】B

【3】A

【4】C

【解析】

試題分析：本文講的是手機(jī)輻射對(duì)人的影響。

【1】D 細(xì)節(jié)理解題。根據(jù)文章第一段中“Mobile phones killed our man.”第二段中mobile phones’ emission(輻射) mobile phones might be doing to the brain.第三段中One of the strange effects comes from the now famous “memory loss”可知，A、B、C三項(xiàng)都符合題意，故選D。

【2】B 推理判斷題。根據(jù)第三段倒數(shù)第二句But he rules out the suggesting that mobile phones have an immediate effect on our cognitive(感知的) abilities. “I’m pretty sure there is no short-term memory.可知，他排除了這一建議，認(rèn)為手機(jī)對(duì)我們的感知能力的影響是直接的。故Prece的態(tài)度是“不同意”。故選B。

【3】A 詞義猜測(cè)題。雖然仍然沒有絕對(duì)的證據(jù)表明手機(jī)確實(shí)對(duì)你的記憶有傷害，使你得癌癥，但一致的意見是：不要驚慌。故“不要驚慌”是一致的建議。故選A。

【4】C 細(xì)節(jié)理解題。根據(jù)第五段中mice exposed to microwave for two hours a day were less likely to develop brain tumours(腫瘤) when given a cancer-causing chemical.可知，一天曝露于微波下兩個(gè)小時(shí)不可能發(fā)展成腦瘤。故選C。

【學(xué)法指導(dǎo)】

任何一篇文章中的句子在內(nèi)容上都不是絕對(duì)孤立的，都跟句子所在的段落及整整篇文章有關(guān)。利用上下文提供的情景和線索，進(jìn)行合乎邏輯的綜合分析進(jìn)而推測(cè)詞義，是閱讀過程中的一大關(guān)鍵，這也是近年來(lái)高考考查的熱點(diǎn)。最常見的就是利用上下文語(yǔ)境、常識(shí)和語(yǔ)法關(guān)系推斷詞義。

①抓住所需推斷詞匯前后的“mean”或系動(dòng)詞或破折號(hào)等直接定義該詞的部分。

②抓住文章主旨與該段所表達(dá)的中心。特別對(duì)于議論文要牢記論點(diǎn)與論據(jù)的相互支撐關(guān)系。

③通過例證、比喻、對(duì)照、插入語(yǔ)等語(yǔ)法結(jié)構(gòu)推斷詞義。

30小題詞義猜測(cè)題。雖然仍然沒有絕對(duì)的證據(jù)表明手機(jī)確實(shí)對(duì)你的記憶有傷害，使你得癌癥，但一致的意見是：不要驚慌�？芍骸安灰@慌”是一致的建議。故選A。

The people who learn to make the best life adjustments cultivate the habit of going with the flow. For example, they refuse to sweat the small stuff, they remain flexible to life changes.

As the saying goes, “ 【5】 ”. That's the best advice for anyone who wants to make the best life adjustments and win!

【題目】While inventions like the wheel and the Internet have changed the way the world works today, there are some creations that never quite got off the ground. Let’s look at the strangest inventions from across the globe.

THE TOMATO-FEEDING ROBOT

Japanese juice seller, Kagome, invented a robot that will feed you tomatoes with its long metal arms extended on either side of your face while you run. Originally created for the Tokyo Marathon, the robot even has a timer so that tomato-eating runners won’t use up their supply too quickly.

THE ROLLING BENCH

It’s lunchtime and many people may be looking for a park bench to sit on, but the rain has made every surface humid. This is when the rolling bench comes in. When one side is too wet, a handle on the side can roll up another dry side for better sitting conditions. The inventions come from designer Sung Woo Park, from Seoul in South Korea.

THE LED SLIPPERS(拖鞋)

We all hate hurting our toes in the dark, but a revolutionary footwear design can prevent this from happening again. The slightly strange LED slippers are designed to be comfortable, yet shine your path at night. With two in-built LED lights at the top of each slipper, the users can direct their toes at any area that needs light.

THE FOOT-POWERED BICYCLE

It’s the unusual invention of German designers Tom Hambrock and Juri Spetter. Besides an unusual appearance, its function is also slightly strange, as the user must run to get the bicycle moving. As soon as the riders have enough momentum(動(dòng)力), they’re able to rest their feet on the back wheel and use the handlebars to control its direction.

【1】What can we know about the tomato-feeding robot from the text?

A. It’s popular with lazy eaters.

B. It was the creation of a Korean.

C. It was designed for a sports event.

D. It has two plastic arms.

【2】Which of the following can replace the underlined word “humid” in the text?

A. Dirty. B. Wet.

C. Unsafe. D. Uncomfortable.

【3】Which invention was designed for its users’ safety?[

A. The LED slippers.

B. The rolling bench.

C. The foot-powered bicycle.

D. The tomato-feeding robot.

【4】What can we infer about the inventions mentioned in the text?

A. They bring us speed improvement.

B. Their inventors are all from Asia.

C. They are powered by electricity.

D. They can serve us in different ways.

【題目】Knowing how and when to say goodbye is often difficult, even in informal situations. 【1】 It will help you maintain your relationships and let people know you care. It’s also easier than it seems sometimes. Read on to learn how to recognize opportunities and predict others’ needs when you leave.

Recognize when to leave. When you’re at any kind of party, or even a one-on-one conversation，it can be difficult to get away. Learning to recognize good opportunities to leave will make a goodbye much easier. 【2】 If more than half the people have left, it might be a good time to leave.

【3】 Overstaying your welcome is rude, but it can often be difficult to distinguish. People don’t like telling you that they’d like you to leave，so try to watch for signals. This may be some other family members starting to check their watch or even pack up or the fact that there is hardly anyone left.

Make plans to see each other again. Saying, “See you at school tomorrow” or “Can’t wait to see you again at Christmas” keeps the goodbye light and focused forward. If you haven’t already made plans, use it as an opportunity to make them.【4】

Tell the truth. It can be tempting to come up with a “good excuse” when you’re ready to leave. You don’t need to. 【5】 It doesn’t need to be any more complicated than that.

A. Watch body language.

B. Leave when you want.

C. Notice if the crowd seems to be decreasing.

D. Even saying, “See you soon” suggests just that.

E. If you want to leave, just say, “I’ll be going. See you later.”

F. But learning to say goodbye appropriately is a must-have skill.

G. Don’t make plans with people you don’t really care about saying goodbye to.
