Every time you go to the supermarket you come away with your purchases packed in plastic bags. But wouldn’t it be kinder to the environment if you asked for paper bags instead?
The answer is not as easy as it might seem. Environmentalists say there are drawbacks to using both plastic bags and paper bags.
80 percent of groceries in the US are packed in plastic bags and the numbers are becoming huge. Consumers use between 500 billion and 1 trillion plastic bags per year worldwide.
Some experts believe that all these bags harm the environment. Plastic takes hundreds of years to break down and, as it does so, poisonous materials are released into the water and soil.
Further damage is caused if plastic bags enter the sea. For example, endangered sea turtles cannot tell the bags from jellyfish, their main source of food, and often choke on them.
However, this kind of bag does have its advantages.
Paper bags use more energy and create more waste than plastic bags. Plastic bags require 40 percent less energy to produce and cause 70 percent less air pollution. They also release as much as 94 percent less waste into the water than paper ones do.
But paper bags do break down more quickly than plastic bags. They don’t endanger wildlife, either.
So what should we do? One possible solution would be to use biodegradable plastic bags. “Biodegradable” means that the bags break down naturally just like a piece of banana peel when it is left outside.
But until biodegradable technology improves, it might be easier to pack things you buy in reusable cloth bags.
1.Compared to paper bags, plastic bags ______.
A. produce 6 percent more waste
B. can be made biodegradable more easily
C. can be used as a source of food
D. save 40 percent of the energy
2.By saying “The answer is not as easy as it might seem,” (in paragraph 2) the writer means _____.
A. biodegradable plastic bags can compete with paper
B. paper bags seem to be kind to environment
C. it’s difficult to say whether plastic or paper bags are better for the environment
3.What does the author suggest people use at the present time?
A. Paper bags
B. Plastic bags
C. Biodegradable plastic bags.
D. Cloth bags.

If Confucius were still alive today and could celebrate his September 28 birthday with a big cake,there would be a lot of candles.He’d need a fan or a strong wind to help him put them out.
While many people in China will remember Confucius on his special day,few people in the United States will give him a passing thought.It’s nothing personal.Most Americans don’t even remember the birthdays of their own national heroes.
But this doesn’t mean that Americans don’t care about Confucius.In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.
In the past two decades,the Chinese study programs have gained huge popularity in Western universities.More recently, the Chinese government has set up Confucius Institutes in more than 80 countries.These schools teach both Chinese language and culture.The main courses of Chinese culture usually included Chinese art,history and philosophy.Some social scientists suggest that Westerners should take advantage of the old Chinese wisdom to make up for the drawbacks of Westerners philosophy.Students in the United States,at the same time,are racing to learn Chinese.So they will be ready for life in a world where China is an equal power with the United States.Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.
So the old thinker’s ideas are still alive and well.
Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West.
As for the old thinker,he will not soon be forgotten by people in the West,even if his birthday is.
1.The first paragraph is mainly intended to_________.
A. provide some key facts about Confucius

Having drank too much, Alfred was driving along the country road at top speed while his car ran into an old man who was walking across the road. After looking around and thinking there was not a single person see the accident, he drives off without taking the old man to the hospital. The old man was frightening but kept the car number on his mind. About one month late, they went to court. Alfred’s lawyer said:” Alfred is experienced driver of more than 20 years.” “ If experience can prove that, here, you see, the old man had walked safe for over 60 years,” the old man’s lawyer replied.

We each have a unique genetic (基因的,遗传的) make-up. Every cell of your body has the same set of about 100,000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of your skin to the way your brain works. You have one of several billion binations of DNA which e from the random(随机的,任意的) mixing of your parents’ genes. Except for identical twins (同卵双胞胎), no one has the same bination as another person. You are unique! You are unique in another way too: in the way you are raised and all the experiences you have from before birth to adult life. These experiences influence you, your behaviour and attitudes, and the choices you make.
But are genes or life experiences more important in shaping your appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births---some are identical and others are non-identical twins. Identical twins are special because they share exactly the same genes and often the same environment. Non-identical twins are more like ordinary brothers and sisters.
Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit. For example, we know that eye problems, like short-sightedness, are mostly genetic. But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Non-identical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than non-identical twins.
Scientists are trying to identify the different genes that influence our behaviour. Some people are thrill-seekers and get into risk-taking and adventurous activities. They take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects this.
We could ask, “Are our lives determined by our genes or our upbringing?” Scientists are learning more all the time, but it is certainly true that both are important in making us who we are.
1.What is the main idea of the first paragraph?
A. We cannot easily change our physical appearance.
B. How we turn out depends on our parents’ genes.
C. Everyone has a physical double somewhere in the world.
D. Both our genes and our experiences make us who we are.
2.Why are scientists studying twins?
A. To find out how many twins are born every year.
B. To discover what shapes us as individuals.
C. To pare differences between twins.
D. To study brother-and-sister relationships.
3.According to the passage, __________.
A. one in 70 twins are genetically identical
B. non-identical twins are usually not of the same sex
C. twins separated at birth behave exactly the same
D. identical twins are genetically the same
4.Which of the following is most affected by experience according the passage?
A. Eating habits. B. Eye-sight.
C. Pain resistance. D. Marriage patterns.
5.What does the underlined “this” in Paragraph 4 refer to?
A. Our love of sport.
B. Our attitude to risk-taking.
C. Our skill at bungee jumping.
D. Our ability to take drugs.
