     Medical drugs sometimes cause more damage than they cure. One solution to this problem is to
put the drugs inside a capsule, protecting them from the body-and the body from them-until they
can be released at just the right spot. There are lots of ways to trigger (引發(fā)) this release, including
changing temperature, acidity, and so on. But triggers can come with their own risks-burns, for example.
Now, researchers in California have designed what could be a harmless trigger to date: shining near-infrared light (NIR, 近紅外線) on the drug in the capsule.
     The idea of using light to liberate the drug in the capsule isn't new. Researchers around the globe have
developed polymers (聚合物) and other materials that begin to break down when they
absorb either ultraviolet (UV, 紫外線) or visible light. But tissues also readily absorb UV and
visible light, which means the drug release can be triggered only near the skin, where the light can
reach the capsule. NIR light largely passes through tissues, so researchers have tried to use it as a
trigger. But few compounds (化合物) absorb NIR well and go through chemical changes.
     That changed last year when Adah Almutairi, a chemist at the University of California, San
Diego, reported that she and her colleagues had designed a polymer that breaks down when it
absorbs NIR light. Their polymer used a commercially available NIR-absorbing group called
o-nitrobenzyl (ONB). When they catch the light, ONB groups fall off the polymer, leading to its
breakdown. But ONB is only a so-so NIR absorber, and it could be poisonous to cells when it
separates from the polymer.
     So Almutairi and her colleagues reported creating a new material for capsules that's even better.This
one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains
reactive(易反應(yīng)的) components that make it highly unstable in its polymeric form, a feature Almutairi
and her colleagues use to their advantage. After polymerizing the cresols, they cap each reactive
component with a light-absorbing compound called Bhc. When the Bhcs absorb NIR light, the reactive
groups are exposed and break the long polymer into two short chains. Shining additional light continues
this breakdown, potentially releasing any drugs in the capsule. What's more, Almutairi says, Bhc is 10
times better at absorbing NIR than is ONB and is not poisonous to cells.
1. According to the passage, which of the following could be the best trigger?
A. Temperature change.  
B. NIR light.  
C. Acidity change.      
D. UV light.
2. Why is ONB unsatisfactory?
A. It breaks down when it absorbs NIR light.
B. It falls off the polymer and triggers drug release.
C. It has not come onto the market up till now.
D. It is not effective enough and could be poisonous.
3. Which word can be used to complete the following process of changes?
A. protected    
B. formed    
C. exposed    
D. combined

To me, life without music would not be exciting. I realize that this is not true for everybody. Many people get along quite well without going to the concert, or listening to the record. But music plays an important part in everyone’s life, whether he realizes it or not. Try to imagine, for example, what films or TV plays would be like without music. Would the feelings, the moving plot(情節(jié)),and the greatest interests, be as exciting or dramatic(戲劇性)?I’m not sure about it.

   Now, we have been speaking of music in its more common meaning—the kind of music we hear in the concert hall. But if we look at some parts of music more closely, we discover them in  our everyday life too—in the rhythm(旋律)of the sea, the melody of a bird in the woods and so on. So music surely has meaning for everyone, in some way or other. And, of course, it has special meaning for those who have spent all their lives working on playing or writing music.

   It is well said, “Through music a child enters a world of beauty, expresses himself from his heart, feels the joy of doing things alone, learns to take care of others, develops his mind and makes his body strong.”

1.  What does the writer say more about in the passage?

A. Life full of music.

B. Life without music.

C. Importance of music.

D. Development of music.

2From the text, we know that many people     .

A. don’t realize the importance of music

B. get along quite well without music

C. go to the concert instead of enjoying films

D. think music would be less exciting than films

3In the writer’s opinion, if there was no music in films or TV plays,      .

A. the cinema and theatre would be quiet

B. we would lose some of the audience

C. everything would be as exciting as before

D. it would be hard to imagine the result

4What does the underlined word “melody” mean in the text?

A. Flying                  B. Looking

C. Singing                 D. Living

Make me laugh, now!

  In a room filled with cigarette smoke and the smell of beer, people are laughing as a little man on stage talks.This is stand-up, a major form of live entertainment in the West.

  It could be held in a theatre or just a bar.The basic idea is that a person, or sometimes two, "stands up" on a stage and makes the audience laugh.

  The performer could tell a story or lots of little stories.He could just tell jokes or discuss the most serious issues of the day.The point is that the audience expects to be made to laugh.

  Audiences at stand-up shows are not polite.If they don't find the person funny they will shout out.These people are called "hecklers"(詰難者).If a comedian

(喜劇演員)is good he will be able to shout back at the heckler with some clever response(應(yīng)答).

  Normally, the comedian has prepared a script, which he has learnt.But often they might think of something different while on stage.This is called improvising

(即興發(fā)揮).

  Different stand-up comedians have different styles.Some are called straight men.These will never laugh or smile and will try to appear very serious even though what they are talking about is very funny.Others play the fool.These act and say things that are very stupid so that you can't help laughing at them.Another type is

the person who can copy famous people's voices.They will pretend to be someone famous in a funny situation.

  Stand-up comedians will talk about anything from sex to polities, from family to animals.To a stand-up comedian everything is funny.

Count Me Out

  Call me old-fashioned.Call me old.Call me what you want, but I refuse to become part of this new Internet world.

  I do not possess a computer at home or at the office.Actually, I stopped going to an office 35 years ago, when all communications were done with a pen, a typewriter, or, if the matter was of world-shaking importance, over the telephone.Likewise, if you like something advertised in a newspaper or magazine, you visited the shop selling it at the given address, or you phoned the number shown.Then you spoke to the fellow and asked for further details.

  Tell me what you think of the following ad that appeared the other day in the newspaper.It was for a cure for cancer and this is what it said:“Awareness is the key.Visit spfulford.com at the awareness site.” There was no address or telephone number for the site.So what do unfortunate people without a computer do if they are seeking a cure for their illness?

  There are, I am told, certain advantages in having access to the Internet.You can, for example, send love messages across the world or even get married to someone that you meet online.This bit doesn’t interest me; I have been happily married for 60 years.There are, of course, other activities for Internet users besides finding love.They can pay bills, order groceries, or discuss with their doctors.

  And this is by no means all.More amazing things are yet to come in the near future.I read a newspaper report recently that quoted Stephen Hawking, an important British scientist.“The complexity of a computer as it exists today is probably less than the brain of an earthworm,” he said.“But, as technology advances, computers will become more complex, and a time may come when the Internet may develop ‘consciousness.’ In other words, the Internet will be able to think, have feelings, and may well be able to act on its own.”

  If Professor Hawking is right, I may change my attitude to computers.As I grow older each day, I would like one of those that not only thinks for me but also accepts responsibilities for all my mistakes.

(1)

What’s the meaning of the title “Count Me Out”?

[  ]

A.

B.

Computers are trying to take control of life.

C.

Modern technology pushes old people away.

D.

Do not expect me to be a supporter of the Internet.

(2)

According to Paragraph 2, the author thinks computers are _________

[  ]

A.

unnecessary

B.

convenient

C.

expensive

D.

advanced

(3)

What might the author like about the future computer?

Taking blames.

B.

Curing illnesses.

Delivering messages.

D.

Responding to emotions.
