Making greener choices, from the food you eat to the way you travel, can improve your health．A recent article advises people should try low–carbon (低碳) lifestyles which could be the most important contribution to yourself, even the earth．Some guidelines follow:

1．Use your own power rather than oil whenever you can     

Burning oil in your car makes pollution like carbon dioxide (CO2) that causes global warming．Cutting down on driving and using your own two legs helps cut global warming pollution and helps reduce weight problems over time without dangerous diets or surgery．

If all Americans used foot instead of engine as daily exercise during normal travel, we could reduce our oil dependence by more than a third．Besides, by using a push mower(剪草机) instead of a power mower to cut your lawn, you can also cut up to 80 pounds of CO2 per year! And you’ll get a great workout!

2．Drop the bottled water, drink tap (自来水)     

Drinking plenty of water is important during hot weather or when exercising．You may think bringing bottled water with you can be both convenient and harm-free to the environment．But, you may change your mind if you see the truth below in 2006, 30 billion plastic water bottles were made, which used the amount of more than 17 million barrels(桶)of oil–enough to fuel more than one million cars for a year, and produced more than 2.5 million tons of carbon dioxide．

If you have worries about your tap water, clean it regularly! The truth is that tap water is no worse than bottled water ant it saves much money．

3．Choose foods carefully

There are some general ways you can follow that are good for you and the planet:

a．Eating less meat and more grains and vegetables helps reduce the need to cut down forests to grow the food for animals

b．Buying local food may be environmentally–friendly．Locally grown foods often use much less oil in transport than the foods coming from somewhere far away, which would help reduce CO2 amount．

1．What benefit can people make if they walk more but drive less?

A．More pollution will be made during the process．

B．There will be no obvious effect on reducing the amount of carbon dioxide．

C．Every year, more than 30% of the oil can be saved, which will help weaken global warming．

D．People’s weight will stay the same, and they still need to go on a diet to get thinner．

2．Why should we change our preference to bottled water?

A．Bottled water contains more good things for our health．

B．Tap water is not clean enough for people to drink．

C．Bottled water is more expensive than tap water for its better quality．

D．Tap water is as good as bottled water, which wastes so much resource during its production．

3．If you mean to protect the environment, you will ________．

A．often buy food from foreign countries         B．seldom eat meat for dinner

C．usually drive to work and home                D．never boil tap water to drink

4．Which of the following statements is TRUE?

A．Low–carbon lifestyles bring more harm than benefit to nature．

B．Man’s daily life activities have no effect on the changes of the environment．

C．What you eat can not only be good for your health, but also for the health of the earth．

D．The choice of food is completely personal, which won’t be important for nature at all．

How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question, as Tracy Smith reports in our Cover Story.

There are now more than a thousand genetic（基因的）tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’（老年痴呆症）.

“If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up.” Said Dr. Robert Green, a Harvard geneticist.

“Every ache and pain,” Smith suggested, could be understood as “the beginning of the end.”“That ’s right. If you ever worried you were at risk for Alzheimer’s disease, then every time you can’t find your car in the parking lot, you think the disease has started.”

Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s. It was thought that people who got bad news would, for lack of a better medical term, freak out. But Green and his team found that there was“no significant difference”between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.

Bottled water or tap water(自来水)? The answer very much depends on how you are affected by advertising. Many British people certainly are easily influenced by ads. Bottled water is a￡2 billion business every year in the UK.

So why do we buy it? A study found that people tend to believe that bottled water is somehow healthier, but don’t know why. Perhaps it is because it costs more. Bottled water costs around 500 times more than tap water.

Manufactures(制造商) would make you believe that bottled water is naturally cleaner and tastier than tap water, but many, in fact, get their water from the same place that tap water comes from. Indeed, there is nothing natural about the way much bottled water is made.

Apart from the oil used to make the plastic bottles, the water causes much more pollution than tap water. Producing and transporting bottled water result in hundreds of times more CO emissions(排放), and that’s before considering the effect the plastic bottles have on the environment —only around a quarter are recycled.

OK, so it is not “green” to drink bottled water, but what about your health? Isn’t tap water full of bad things? If you live in a country where water standards are poor, then you have cause for concern. But if you live in Britain, you can be confident that tap water has been filtered(过滤) and tested, and is perfectly safe to drink. In fact, Britain’s tap water is one of the safest in the world.

But does bottled water really taste better? Tap water can taste different in different areas. It may contain different amounts of minerals, which can affect its flavor. If the taste bothers you, the solution is to pour tap water into a bottle and put it in the fridge, or even buy a water filter. This ought to make it palatable. Then smile at the thought of the money you have just saved.

60. According to the passage, compared to tap water, bottled water _____.

A. is much healthier

B. contains more minerals

C. is not environmentally friendly

D. is produced in a more natural way

61. The underlined word “palatable” in the last paragraph probably means “_______”.

 A. Healthy   B. light   C. tasty   D. warm  

62. What is the author’s attitude towards using tap water in Britain?

A. Negative.   B. Positive   C. Interested.   D. Worried

63. How is the passage mainly developed?

A. By giving examples.

B. By making comparisons.

C. By following time order.

D. By telling personal experiences.

阅读下面这封中学生来信（摘自 China Daily 21 Century）.

Dear Editor:

I am a new student at Haining Hongda Senior High School. My home is far from Haining, so I must live at school. This is the first time for me to get away from my parents. I feel very sad. When I left home, I couldn’t help tearing myself away from them. I do not want to be alone at school, and I am a shy girl. I have been crying in bed at night these days. I want to stay at home forever. I miss my parents very much. Could you tell me what to do ?

Your early reply is expected.

Regards

Amy
