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.

A. by human bodies

When I was about 10, I was walking down the street with my mother. She stopped to speak to Mr Lee. I knew I could see Mr Lee anytime around the neighborhood, so I just stood there. After we passed him, my mother stopped and said something unforgettable, "You let that be the last time you ever walk by somebody you know without opening your mouth to speak, because even a dog can wag its tail when it passes you on the street." That sentence sounds simple but it made me become who I am.

At work, I used to say hello to the president of the company and ask him how our business was doing. But I also spoke to the people in the cafe? and people who cleaned the buildings, and asked them how their children were doing, for every single person deserves to be accepted, no mater how humble (卑微的)they are. I remember that after a few years of passing by the president, I had the courage to ask him for a chat. We had a great talk. At some point, when I asked him how far he thought I could go in his company, he said that if I wanted to, I could get all the way to his seat.

I've become vice president, but that hasn't changed how I treat people. I speak to people wherever I am. Speaking to people creates a pathway into their world, and it lets them come into mine, too. The day you speak to someone who has his head down and then see him lift it up and smile, you will realize how powerful it is just to open your mouth and say hello.

Forgiveness

To forgive is a virtue, but no one has ever said it is easy. When someone has deeply hurt you, it can be extremely difficult to let go of your hate. However, forgiveness is possible, and it can be surprisingly beneficial to your physical and mental health. People who forgive show less sadness, anger and stress and more hopefulness, according to a recent research.

1. Try the following steps:

Calm yourself. 2. You can take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, or someone you love.

Don’t wait for an apology. Many times the person who hurt you does not intend to apologize. They may have wanted to hurt you or they just don’t see things the same way. 3. Keep in mind that forgiveness does not necessarily mean becoming friends again with the person who upset you.

Take the control away from your offender(冒犯者). Rethinking about your hurt gives power to the person who causes you pain. Instead of focusing on your wounded feelings, learn to look for the love, beauty and kindness around you.

4. If you understand your offender, you may realize that he or she was acting out of unawareness, fear, and even love. You may want to write a letter to yourself from your offender’s point of view.

Don’t forget to forgive yourself. 5. But it can rob you of your self-confidence if you don’t do it.

A. Why should you forgive?

B. How should you start to forgive?

C. Recognize the benefits of forgiveness.

D. Try to see things from your offender’s angle.

E. For some people, forgiving themselves is the biggest challenge.

F. To make your anger die away, try a simple stress-management technique.

G. If you wait for people to apologize, you could be waiting an awfully long time.

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
