With the development of society, the choice of food and drinks for children is more diversified than ever before. However, every coin has two sides. Many facts suggest that children are overweight and the situation is getting worse, according to the statistics. I feel there are a number of reasons for this.

Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants then probably children would buy less take-away food.

There is another argument that blames parents for allowing their children to become overweight. I agree to this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.

There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers. Not only is this an unhealthy pastime(消遣), it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.

The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as guiding them away from fast food shops and bad eating habits.

1.What is suggested by the author to deal with “overweight”?

A. Blaming the shops selling unhealthy and fatty foods.

B. Asking young children to walk to school every day.

C. Living an active life and removing bad eating habits.

D. Not watching TV or playing computer games after school.

2.Which of the following shows the structure of the whole text?

3.The author writes the passage to ______________

A. show people a social problem B. provide facts for government

C. advise solutions to a problem D. compare opinions with people

4.The underlined word “diversified” in the first paragraph most probably means ________.

A. various B. difficult C. expensive D. available

E?reading and e?books are slowly conquering the world.Compared to traditional paper bookse?books in some schools and universities attract more interest because the information flow seems much easier to manage and comes in a greatly higher quantity.

Japan is known for the reform?minded attitude towards the gadget(精巧裝置) world and for the fact that it is one of the first countries that encouraged in the educational system the emailing of homework.

The digital textbook looks like the logical step in the world of learning.It is natural but it is also completely untraditional.

The plan of the largest publishing companies to get in line with the trend is to save a large quantity of paper and make the kids become interested in learning using a cool gadget.Many USA universities and colleges have made students be used to the procedure of downloading the courses and of course the procedure involves interactive software and also the chance of using the computer.

The traditional education system is still unwilling when it comes to giving up books.The standard approach of information taught out of a book and Shakespeare read out of an old school novel makes studying English as traditional as it can be.

In a world where kids would rather see the movie than read a book,the digital age has brought along a completely different flavor to reading.Bringing that flavor in school will make teaching a greener and also a completely different matter.

1.Why are e?books so popular in the world?

AIt's cheap to buy. BIt's effective to use.

CIt's convenient to bring. DIt's the latest fashion.

2.Which of the following words can best take the place of the word “reform?minded” in the second paragraph?

A new study has found evidence of aggressive (攻擊性的) behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children’s behavior.

The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day.

Shakira Suglia, a famous expert, says they’ve found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression.

“For the children who consume four or more soft drinks per day, we see more withdrawn behaviors, which make them hard to get along well with others.”

The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people.

The researchers have determined the link after considering factors like the child’s age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home.

Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons (武器) and show signs of negative social behavior.

1.What section of a newspaper is the passage probably taken from?

A. Scientific TechnologyB. Science Fictions

C. Social NewsD. Health Report

2.The underlined word “withdrawn” in paragraph 4 can probably be replaced by the word ______.

A. backwardB. unsocialC. generousD. friendly

3.Researchers studied the following aspects of the children except ______.

A. ageB. sexC. gamesD. parents

4.According to the research, which of the following is right?

A. Mothers were asked to keep a record of how many servings of soft drinks their children drank over a three-month period.

B. 4 percent of the youngsters have even four or fewer sodas to drink every day.

C. Children who drink no soda show fewer aggressive behaviors.

D. Children with the highest sugar levels tend to carry weapons and show signs of negative social behavior.

5.After a further study on ingredients in soda, Shakira Suglia implies that the direct cause of the aggressive behaviors may be ______.

A. soft drinks B. attention problems

C. caffeine D. social conditions
