In the famous fairy tale, Snow White eats the Queen's apple and falls victim to a curse(诅咒);in Shakespeare's novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pellets(药丸)that contained mercury(水银), believing that it would make them immortal, but they died afterward.

Poison has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?

An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison.

The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars(毛毛虫), frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered with a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.

"Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others."

A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol.

The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances(物质)that we regularly ingest(摄入)-chili, coffee and chocolate-owe their special flavors or stimulating(提神的)effects to chemicals that plants make to poison insects.

1.What does the underlined word "immortal" in Paragraph 1 mean?

A. happy B. not moral

C. living forever D. sick

2.What is the main purpose of the exhibition The Power of Poison?

A. To give people more in-depth knowledge about poison.

B. To teach people how to handle poisonous animals.

C. To inform people about which animals are the most poisonous.

D. To show how poison has been used for medical treatment.

3.Which of the following statements about the Golden poison frog is TRUE according to the article?

A. Its skin can cut off the signaling power of your nerves.

B. It's about the size of a coin.

C. It's the most poisonous animal on display.

D. You can only see it in a rainforest setting of the museum.

4.The stimulating effects of coffee come from ________.

A. natural poison made by the plant

B. the substances that we regularly ingest

C. chemicals produced by poisonous insects

D. its special flavor

Every human being, no matter what he is doing, gives off body heat. The usual problem is how to get rid of it. But the designers of the Johnstown campus (校园) of the University of Pittsburgh set themselves the opposite problem — how to collect body heat. They have designed a collection system which uses not only body heat, but the heat given off by such objects as light bulbs and refrigerators as well. The system works so well that no fuel is needed to make the campus’s six buildings comfortable.

Some parts of most modem buildings — theaters and offices as well as classrooms, are more sufficiently heated by people and lights and sometimes must be air-conditioned (使用空调的) even in winter. The technique of saving heat and redistributing (再分配) it is called “heat recovery”. A few modern buildings recover heat, but the University’s system is the first to recover heat from buildings and reuse it in others.

Along the way, Pittsburgh has learned a great deal about some of its producers. The harder a student studies, the more heat his body gives off. Male students send out more heat than female students, and the larger a student is, the more heat he produces. We may conclude that the hottest prospect for the Johnstown campus would be a hard working overweight mate genius.

1.The heat in the heating system of the Johnstown campus is supplied ________.

A. by human bodies

B. by both human bodies and other heat-giving objects

C. by both human bodies and commonly used fuel

D. by human bodies, commonly used fuel and other heat-giving objects

2.According to the passage, the technique of heat recovery is used ________.

A. to find the producers of heat

B. to provide heat for the hot water system

C. to make the campus more beautiful

D. to collect heat and reuse it

A. the person who suffers most from heat

B. the person who needs more heat than others

C. the person who gives off most heat

D. the person who makes better use of heat

4.Which of the following may be the best title for this passage?

A. A New Heat Recovery System in Pitt

B. Modern Building’s Heat System

C. Body Heat and Its Producers

D. Ways of Heating Building

Six years ago at the age of 35,I suddenly decided I wanted to learn the cello(大提琴).Straight away I rented an instrument and appeared before Wendell Margrave,professor of musical instruction.

"You can be as good as you want to be,"Margrave said rather mysteriously.On a piece of paper he drew the notes E and F.He showed me where to put my fingers on the neck of the cello and how to draw the bow.Then he entered my name in his book: 10 am,Tuesday.Tuesday followed Tuesday,and soon it was spring.

Thus began my voyage out of ignorance and into the dream.E-F,E-F,we played together—and moved on to G.It was a happy time.I was again becoming something new,and no longer trapped as the same person.Surely the most terrible recognition of middle life is that we are past changing.We do what we can already do.The cello was something I couldn't do.Yet each Tuesday this became less and less true.Riding home on the bus one snowy night and learning the score of Mozart's C-Major Quintet(莫扎特的C大调五重奏),I felt the page burst into music in my hands.I could by then more or less read a score,and was humming(哼唱)the cello line,when suddenly all five parts came together harmonically(和谐地) in my head.The fellow sitting opposite stared.I met his glance with tears,actually hearing the music in my head for the first time.Could he hear it too, perhaps?No,he got off at the next stop. As the years slipped by,my daughter grew up,playing the piano well.My goal was that she and I would one day perform together.I also wanted to perform in public with and for my peers,and to be secretly envied.I continued to play,to perform,but it is not the same.Before,when I heard a cello,it was all beauty and light.Now,as the TV camera gets close to Rostropovich's face,I recognize that his smile shows his incredible determination.Even for him,the cello is a difficult instrument that doesn't respect your ambitions.I picked up my cello and practiced.As good as I wanted to be,I am as good as I'm going to get.It is good enough.
