Night of the Living Ants

When an ant dies，other ants move the dead insect out of the nest．This behavior. is interesting to scientists，who wonder how ants know for sure-and so soon-that another ant is dead．

Dong-Hwan Choe，a scientist at the University of California，found that Argentine ants have a chemical on the outside of their bodies that signals to other ants，“I’m dead-take me away．”

But there's a twist to Choe's discovery．Choe says that the living ants-not just the dead ones -have this death chemical．In other words，while an ant crawls around，perhaps in a picnic or home，it's telling other ants that it's dead．

What keeps ants from hauling away the living dead？Choe found that Argentine ants have two additional chemicals on their bodies，and these tell nearby ants something like，“Wait-I'm not dead yet．” So Choe's research turned up two sets of chemical signals in ants：one says，“I'm dead，”the other set says，“I'm not dead yet．”

Other scientists have tried to figure out how ants know when another ant is dead．If an ant is knocked unconscious，other ants leave it alone until it wakes up．That means ants know that unmoving ants can still be alive．

Choe suspects that when an Argentine ant dies．the chemical that says“Wait-I'm not dead yet” quickly goes away．Once that chemical is gone，only the one that says“I'm dead”is left．“It's because the dead ant no longer smells like a living ant that it gets carried to the graveyard(墓地)，not because its body releases new，unique chemicals after death，”said Choe．When other ants detect the“dead”chemical without the“not dead yet”chemical，they haul away the body．This was Choe's hypothesis(假设)．

To test his hypothesis，Choe and his team put different chemicals on Argentine ant pupae(蛹)． When the scientists used the“I'm dead”chemical，other ants quickly hauled the treated pupae away． When the scientists used the“Wait-I'm not dead yet”chemical，other ants left the treated pupae alone． Choe believes this behavior. shows that the“not dead yet”chemical overrides(优胜于)the“dead”chemical when picked up by adult ants．And that when an ant dies，the“not dead yet”chemical fades away． Other nearby ants then detect the remaining“dead”chemical and remove the body from the nest．

The phrase“this death chemical”in paragraph 3 refers to

A．the chemical that contains poison．

B．the chemical that announces death．

C．the chemical that prevents death．

D．the chemical that causes death．

W: Charles, among other things, you regarded as one of the America’sgreat masters of the blues. A musical idiom does essentially about loss,particularly the loss of romantic love. Why does love die？

M: People often get into love affairs because they have unrealisticexpectations about somebody. Then when the person doesn’t turn out to be whothey thought he or she was, they start thinking maybe I can change him or her.That kind of thinking is a mistake. Because when the dust settles, people aregoing to be pretty much what they are. It’s a rare thing for anybody to be ableto change who they really are. And this creates a lot of problems.

W: At 62, you continue to spend a large percentage of your lifetouring. What appeals to you about life on the road？

M: Music, I don’t especially love life on the road, but I figure if youare lucky enough to be able to do what you truly love doing, you’ve got theultimate of life.

W: What’s the most widely-held misconception about the life of a famousmusician？

M: People think it’s all glamour. Actually we have the same troublesthey do. Playing music doesn’t mean life treats you any better.

W: How do you feel about being recognized everywhere you go？

M: You think I be used to it by now. But I still find it fascinating.You go to a little town in Japan, where nobody speaks English, yet they knowyou on side and know all your music. I’m still amazed by the love peopleexpress for me and by music.

Q12: What does the man sayabout most people when they get into love affairs？

Q13: What does the man sayabout himself as a singer on the road most of his life？

Q14: What do most peoplethink of the life of a famous musician？

Q15: How does the man feelwhenever he was recognized by his fans？

nt, I am filled with mixed feelings. It makes me happy and excited that I’ll see my beloved wife and children soon, but at the same time I don’t want to bid farewell to you, my dear students and friends as well as Tianjin, your beautiful city.

In fact, I regard Tianjin as my second hometown, and the students and teachers here as my family members and best friends. I’ll never forget the warmest welcome you gave me when I first arrived in Tianjin. I’ll never forget the day on which you took me to the hospital when I fell ill an the dumplings that Li Ming’s parents prepared for me that night.

Yet, I still remember you were all laughing at me when I was trying to use chopsticks for the first time in Tianjin Food Street, but do you know that now I prefer chopsticks to knives and forks？

I’m very glad to see the great progress you’ve made in your English and the prosperity of vocational education in Tianjin. I am told that many graduates from this college are devoting themselves to the construction of Tianjin now. I believe your future is bright and so is the future of Tianjin.

Now I’m leaving soon, but I have a strong desire to come back to Tianjin, back to my beloved school with my family as soon as possible.

Best wishes!

Thank you!

ving to say goodbye as if it's the last time they' re ever going to see me is beginning to wear out my friends. Some of the more unfortunate must have said goodbye at least three or four times. Much to everyone' s delight, I will be setting off this Saturday, but getting all the necessary visas (签证) for the journey has been far from quick, cheap or straightforward.

Getting a Chinese visa was easy enough. The Mongolian embassy (大使馆) seemed a bit unprepared for me, or in fact any other tourist, wanting to visit the country in winter and it took half an hour of knocking at the door before I got an answer. The Mongolian visa, however, has a map of the country in the background that should come in handy if I get lost out on the grassland.

It was getting a Russian visa that had me wondering if I'd ever be able to leave. The requirements for the visa, especially for the trip that ! plan to take, were a mountain of paperwork. I was required to prove, for example, where and when I plan on staying in each city and what train I plan to catch between cities.

I've spent a lot of time preparing for this trip, but ! still have no idea what to expect on this journey. The planning and packing has taken my mind off any worries I have so now everything is ready and I just want to get going. I'm sure I will see some interesting people and see some wonderful sights, and the sense of the unknown makes it all the more exciting.

How do the writer's friends feel about the delay of his trip？

A．Grateful.

B．Impatient.

C．Delighted.

D．Worried.

A.Is it still available

B.Is it still empty

C.Is it still free

D.Is it still blank
