We humans are sweet on sugar. That makes sense. All animals need sugar to live. It ' s the fuel that powers our cells. So it' s not surprising that we ' re born to want the sweet stuff.

Sugar stores the sun' s energy like a battery. After a meal,your body breaks down foods into their building blocks. It uses some sugars for energy right away. The rest get stored for the body to break down later. It ' s a myth that sugar makes you extremely excited, but having a sugary snack can give you a quick burst of energy. That ' s because the sugars in sweet foods are easy for your body to turn into fuel. When you eat other kinds of foods,like vegetables, it takes longer for your body to break the sugars down.

These days it' s easy to find sweet snacks. Sodas, candy, cakes and even foods that seem healthy , such as yogurt,can be packed with sugar. Food makers add sugar,because they know that to humans, sweet makes everything taste better. Americans eat about 20 teaspoons of extra sugar everyday. That' s way more than what is good for us.

Eating too much sugar can cause more than a stomach-ache. It can make people overweight, decay the teeth and even cause diabetes. However, experts aren ' t worried about naturally sweet foods- the problem is added sugar. So go ahead and enjoy a sweet apple or even a sugar-rich carrot that are also full of vitamins and other good stuff.

Even cake　 is great once in a while , as long as you don ' t overdo it. After all, no one wants life to be dull. And your body needs its fuel!

1.The first two paragraphs are mainly developed by _'

A. cause and effect.　　 B. problem and solution.

A. no one wants life to be boring.

B. we ' re born to want the sweet stuff.

C. so-called healthy food can be packed with sugar.

D. sugar is the fuel for the plants and animals on the Earth.

3.What does the author want to stress in Para. 4?

A. We' d better say no to sweet foods.

B. Experts are worried about added sugar.

C. Eating too much sugar is bad for our health.

D. We ' d better consume sugar from natural sources.

We are humans，and we all make mistakes. The mistakes that we make are not usually on purpose，whether it is breaking a vase，or not completing a task.　 1.This article will provide you with ideas as to what to do once a mistake has been made.

Admit that you make a mistake as soon as you discover it. Delaying it longer will only make you feel worse，or may drive you toward making the wrong decision to try and cover it up.

2. Do not play the“blame game"．Most people are smart enough to realize that this is just a poor attempt to protect yourself. Perhaps you gave a task to another person and it was never completed. But is it really the entire fault of the person you gave the task to or is it partially your fault for not following up? Keep this in mind before placing the blame on someone else.

3. Maybe you broke your mother's favorite vase，or even forgot a friend's birthday. Just an apology can sometimes be viewed as a“quick fix"，and apologizing and asking to be forgiven gives the person opportunity to forgive you.

Offer some compensation（补偿）for loss，damage，or injury caused. 4. By doing this，it may soften the blow to the person we've disappointed.

Learn from your mistakes. In the case of a job or a task，write a“to-do" list with the deadline before leaving the meeting. As for forgetting a birthday，put the birthday on an electronic calendar for next year.

Do better next time. 5.We should try to understand what happened and try to make sure that it won't happen again.

A. Take responsibility.

B. Never repeat your mistakes.

C. Apologize and ask for forgiveness.

D. People’s faith in us can reduce quickly.

E. So sometimes it is necessary to write a letter to say sorry.

F. But not everyone knows how to admit making a mistake.

G. Offer to immediately complete the late task or pay for the vase.

Whatever our differences as human beings are, we all think we’re more like the rest of the animal world than we realize. It is said that we share 40 per cent of our genetic（遗传的）structure with the simple worm.

But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome（染色体组.

To help them do this, they turned to the worm. The nematode（线虫类的）worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better.

What the worm told Sir John and his colleagues was that each of cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up.

Many of the diseases that humans suffer from happen when these instructions go wrong or are not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death.

1．Sir John Sulston got a Nobel Prize for Medicine because he has______.

A．found that human beings are similar to the worn

B．got the fact we share 40 per cent of our genetic structure with the simple worm

C．found the computer which controls each of the cells in the human body

D．proved that cell death is programmed

2．People might be seriously ill if the cells in heir body______-.

A．grow without being instructed B．die regularly

C．fail to follow people’s instructions    D．develop in the human body

3．The underlined word “they” (paragraph 5) refers to_________-.

A．cell deaths                 B．diseases           C．instructions            D．cells

4．What is the subject discussed in the text?

A．The theory of programmed cell deaths.

B．A great scientist—Sir John Sulston.

C．The programmed human life.

D．Dangerous diseases.
