The world hasn’t seen a pandemic (流行疾病) in 41 years，when the “Hong Kong” flu crossed the globe and killed about one million people worldwide．If H1N1 flu reaches pandemic levels，what would happen next?

  The outbreak of SARS in 2003 rang alarm bells as potential pandemics．Although it jumped

the “animal-to-human” barrier，neither disease changed enough to enable human-to-human infection．Strictly speaking，SARS did not become pandemics because it was too good at killing their hosts．For a pandemic，it needs to be able to maintain human-to-human contact without killing its host off．

H1N1 flu is already a man-to-man disease，which makes it much more difficult to manage．And H1N1 flu appears much more infectious than SARS．

But the WHO warns，it cannot say whether or not it will indeed cause a pandemic．According to experts，here’s what the world might see if there is another pandemic，based on past experience．

    The disease would skip from city to city over an 18-to-24 month period，infecting more than a third of the population．World Health Organization officials believe as many as 1.5 billion people around the globe would seek medical care and nearly 30 million would seek hospitalization．Based on the last pandemic and current world population，as many as 7 million people could die．Hospitals will become overcrowded；schools will close；businesses will close；airports will be empty．Business will become very bad，as people avoid as much social contact as possible．

    Health facilities will become overrun with patients and there would be less-than-adequate staffing，as medical health professionals fall ill themselves and that would result in higher deaths．

    The very young and very old will likely be the most susceptible (易受感染的) to the illness．Experts warn，much is still unknown about the current H1N1 flu virus and its severity and it is too early to say whether it will lead to a pandemic．Right now，the focus is on finding answers and controlling the spread．

A car needs gas to run as your body needs food to work for you. Eating the right kinds of food is very important. A good eating habit can help your body grow strong if you take care of what you eat.

   There are four main food groups altogether. The dairy group has food like milk, cheese and sour milk. The other three groups are the meat and fish group, the fruit and vegetable group, and the bread and rice group. Each meal should have at least one food from all four main groups. With all of these foods together, you will be given enough energy during the day.

   It is easy to get into bad eating habits. You may eat your breakfast in a hurry to get to school on time or you may not have time for a good lunch. It may be easier to eat fish and chips for your supper all the time. But you will find yourself tired and you will not be able to think quickly.

   Watching what you eat will help keep your body healthy and strong. It is also good to take some exercise. It will help you eat more if you take a walk or play games in the open air. Having good eating habits with some exercise is the key to your health.

A. Eggs, tomatoes and chicken.          B. Milk, bread, cabbages and beef.

70. In this passage the writer mainly tells us that ______.

A. every person needs food to grow well

Sport is not only physically challenging, but it can also be mentally challenging. Criticism（批评）from coaches, parents, and other teammates, as well as pressure to win can create a great amount of anxiety or stress for young athletes（运动员）. Stress can be physical, emotional, or psychological, and research has shown that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.

       The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents’ and coaches’ criticisms to heart and find a flaw（缺陷）in themselves.

       Coaches and parents should also be cautious that youth sport participation does not become work for children. The result of the game should not be more important than the process of learning the sport and other life lessons. In today’s youth sport setting, young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game, many parents and coaches focus on the result and find fault with youngsters’ performances. Positive support should be provided regardless of (paying no attention to) the result. Research shows that positive support has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.

64.   An effective way to prevent the burnout of young athletes is __________________.

       A. to make sports less competitive

       B. to make sports more challenging

       C. to reduce their mental stress

       D. to increase their sense of success

65.   According to the passage, sport is positive for young people in that _____________.

       A. it can help them learn more about society

       B. it teaches them how to set realistic goals for themselves

       C. it enables them to find flaws in themselves

       D. it can provide them with valuable experiences

66.   Many coaches and parents are in the habit of criticizing young athletes ________.

       A. without realizing criticism may destroy their self confidence

       B. in order to make them remember life’s lessons

       C. believing that criticism is beneficial for their early development

       D. so as to put more pressure on them

67.   The author’s purpose in writing the passage is _________________.

       A. to persuade young children not to worry about criticism

       B. to stress the importance of positive support to children

       C. to discuss the skill of combining criticism with encouragement

       D. to teach young athletes how to avoid burnout

Something in chocolate could be used to stop coughs and lead to more effective (有效的) medicines, say UK researchers.

    Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.

    The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatments. “While coughing is not necessarily（不一定） harmful it can have a major effect on the quality of life, and this discovery could be a great step forward in treating this problem,” said Professor Peter Barnes.

Ten healthy volunteers were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicines are stopping coughs.

The team found that, when the volunteers were given theobromine, the capsaicin needed to produce a cough was about a third higher than in the placebo group. When they were given codeine they needed only a little higher levels of capsaicin to cause a cough compared with the placebo.

The researchers said that theobromine worked by keeping down a verve activity(神经活动), which causes coughing. They also found that unlike some standard（正规的） cough treatments, theobromine caused no side effects such as sleepiness.

67. According to Professor Barnes, theobromine ______.

A. cannot be as effective as codeine

B. can be harmful to people’s health

C. cannot be taken out of chocolate

D. can be a more effective treatment for coughs

68. What was used in the experiment to cause coughing?

   A. Theobromine.           B. Codeine.                 C. Capsaicin.               D. Placebo.

69. We learn from the text that volunteers in the experiment _____.

   A. were patients with bad coughs                       B. were divided into three groups

   C. received standard treatments                         D. suffered a few side effects

70. Which of the following would be the best title for the text?

   A. Codeine: A New Medicine                        B. Chocolate May Stop Coughs

   C. Cough Treatment: A Hard Problem                 D. Theobromine Can Cause Coughs
