3現(xiàn)在很容易使用互聯(lián)網(wǎng),而且發(fā)送電子郵件在學(xué)生中越來越流行。

【解析】

短文介紹了互聯(lián)網(wǎng)的發(fā)展歷史。起初,互聯(lián)網(wǎng)只是政府使用的。但在20世紀(jì)70年代初,大學(xué)、醫(yī)院和銀行也允許使用互聯(lián)網(wǎng)。然而,當(dāng)時計(jì)算機(jī)非常昂貴,互聯(lián)網(wǎng)很難使用。到了90年代初,電腦變得便宜起來,使用起來也更加容易。如今,互聯(lián)網(wǎng)已經(jīng)成為人們生活中最重要的部分之一。

1be busy doing sth.忙于做某事,talk about談?wù)摚?/span>use the Internet使用互聯(lián)網(wǎng)。故答案為:我們都在忙于談?wù)摵褪褂没ヂ?lián)網(wǎng)

21970s意思是“20世紀(jì)70年代”,be allowed to do sth.被允許做某事,故答案為:但是在20世紀(jì)70年代初,大學(xué),醫(yī)院和銀行也被允許使用網(wǎng)絡(luò)。

3It is +adj. + to do sth.做某物怎么樣;use the Internet使用互聯(lián)網(wǎng);more and more popular among students.在學(xué)生中越來越流行。

【題目】A research study has looked into what happens inside your brain while you read and listen to music. You know that thrill( )you get when listening to your favorite music?That exciting feeling when you hear your favorite songs?According to a recent study,it seems the same thing can happen while you are reading,but not with every kind of text. This opens up interesting questions around how music,reading and emotions are connected in the brain.

The study

“ We decided we would do a comparison between four or five different kinds of texts to see how the brain reacted,”explains Adam Zeman,a scientist. “ The participants ( )lay in an MRI scanner reading the texts,and then we compared brain activity for those five texts.”The texts ranged ( )from deadly boring ones to highly exciting ones,including the Highway Code,parts from novels,and poems.

So what happened in the participants brains while they were reading?

Emotional reaction

As the researchers observed,participants found some texts more emotional than others. When reading these emotional texts,there was higher activity in brain areas related to pleasure and reward—the same areas related to the thrill we get when we listen to music. As Zeman says,“ it perfectly shows that the emotional reaction to literature( 學(xué) )and to music has quite a bit in common. So it doesn't seem to matter whether you are listening or reading if you get a thrill. That was one quite strong finding.”

Introspection(內(nèi) )

There were more interesting findings. Reading poetry is often considered an activity that requires us to use the brain,but did the study find any truth of this?When the participants were reading poems,the team found there was more activity in a particular group of brain areas called the Default Network. “ These areas seem to be related to things we do with our minds when we are resting,like thinking about what's happened to us recently,thinking about what's going to happen in the near future,about other people,and that network seems to be more strongly related to poetry than with other texts,”explains Zeman. This connection between poetry and introspection could be the subject of further research.

Conclusions

The study shows that the different texts activate different areas of our brains when we read. Zeman says,“ the study did support what we thought:reaction to literature was going to be a bit like the one to music in terms of emotion. We felt that we ended up with a great deal of unanswered questions which we hope somebody will continue to ask.”

1What did the research try to find out?

A. How music helps us read different kinds of texts.

B. What kind of texts most people like while listening to music.

C. Why reading different texts causes different reactions in emotion.

D. Whether reading can cause similar emotional reaction like music does.

2What did the participants do in the study?

A. They listened to music. B. They read different texts.

C. They answered many questions. D. They compared brain activities.

3What can we learn from the study?

A. The emotional texts work better for the research.

B. Poetry reading can activate the Default Network.

C. Music helps to bring pleasure and reward.

D. People think about the past when resting.

【題目】Look at your classmates around you. You all wear the same uniform and similar shoes, even similar haircut. Do you want to be different from them? A fashionable and useful backpack can be a great idea!

Backpacks are lightweight and easy to carry on then go. They are great tools for students. They help you to stay organized and tidy. You can keep school things, books and personal items like cell phones and keys neatly(整潔地). With a special and cool backpack, you can also stand out among your classmates.

Tourists also love backpacks. With convenient backpacks, backpackers can move freely from one place to another. Meanwhile, they can also free their hands to do other things like taking photos.

But in the very beginning backpacks were not what we see today.

It is thought that US hiker Dick Kelty invented the first modern backpack in 1951. He used nylon(尼龍) to make backpacks lightweight. Then he added shoulder straps(帶子) and waist straps to transfer much of the weight to the hips(臀部).

Today, backpacks come in different styles.

Rolling backpacks have wheels on the bottom. Users can pull them along the ground if they are too heavy to carry on their shoulders.

And with more people bringing notebook computers to school and work, backpacks also offer space for lightweight electronics. Most of them are in style and can be in good use.

A backpack has already become a symbol of fashion in some way. So, why not carry your fashion with your backpack?

1What’s the writer’s idea for being different from other students?

A. To wear surprising school uniforms.

B. To get best grades.

C. To own a fashionable backpack.

D. To have a usual haircut.

2Students can use a wonderful backpack to _________.

A. take photos B. lose weight

C. stand higher D. keep school things

3Which of the following statement about the first backpack is NOT TRUE?

A. It was invented in the 20th century.

B. The inventor of it is an English hiker.

C. It was made of cotton and nylon.

D. It had shoulder straps and waist straps.

4How many new styles of backpacks are mentioned in this passage?

A. One. B. Two. C. Three. D. Four.

5Where can we read this passage possibly?

A. A fashion magazine. B. A supermarket poster.
