阅读理解。     Dr. Jack M. Gwaltney, Jr. a professor at the University of Virginia School of Medicine, infected
six student volunteers with virus, the most common cause of colds. A few days later, when they were
coughing and sneezing, he gathered 37 more people and divided them into three groups. Group 1
members spent three days and nights in the same room with one of the infected students, separated
by a screen so they couldn"t touch one another. Group 2 sat around a table while an infected volunteer
talked, coughed and sang to them. Group 3 held hands with an infected student for ten seconds, and
then touched their own noses or eyes.
     Although most scientists at the time, the mid-70s, believed colds were spread by virus-laden
droplets spread through the air when infected people coughed or sneezed, Gwaltney suspected
physical contact might play an important role. Sure enough, of the 15 people who had touched a
student volunteer, 11 became infected-compared with only one of those who had been sitting at the
table, and none who had spent three days and nights together.
     "The best evidence we have is that hand-to-hand contact is the most efficient way of transmitting
virus," says Gwaltney. The study was one of a series that helped establish Gwaltney"s reputation as
a leading authority. Dr. Robert Couch says, "It would not be inappropriate to call him Mr. Common
Cold."
     When Gwaltney is asked how close scientists are to finding a cure, he replies: "If you mean "get
rid of", I don"t think we"re going to be able to do that with cold viruses any time soon. But if you
look in the dictionary, you"ll see that "cure" is explained as a successful treatment. And we"re not just
getting more effective at treating the symptoms (症状)-we"re getting at the root cause too. "1. Dr. Jack M. Gwaltney conducted the experiment in order to__________.A. find out the most common cause of colds
B. infect the student volunteer
C. find out the role physical contact plays in the common colds
D. find out the role virus-laden air plays in the infection of colds2. The result of the experiment shows that _________ plays an important role in the infection of colds.A. sneezing at the infected person
B. touching the infected person
C. sitting together with the infected person
D. talking with the infected person3. Which of the following statements is TRUE according to the passage?A. Dr. Gwaltney was sure that hand-to-hand touch is the cause of the common cold.
B. Only one of the people who had spent three days and nights together became infected.
C. Dr. Gwaltney conducted many an experiment as to the cause of colds.
D. Dr. Gwaltney tested altogether 43 volunteers to see how they could develop colds.4. Mr. Common Cold is______.A. a newly-found virus
B. a nickname (绰号) of respect to Dr. Gwaltney
C. a method to cure colds
D. a way by which the other scientists laughed at Dr. Gwaltney5. When Dr. Gwaltney gives a reply in the end of the passage, he means that______.A. they have found the fundamental cause of colds
B. they have managed to wipe out the cold viruses
C. they have meant to experiment more
D. they have made much progress in dealing with colds

     Every country has many good people who help to take care of others. Some high school and college
students in the United States often spend many hours as volunteers in a hospital, orphanage (孤儿院) or
home for the aged.
     They read books to the people who must be in these places or they just visit them and play games or
listen to their problems. Other young people volunteer to collect food or money, or they work in the
homes of people who are sick or old. They paint, clean or repair their houses, do their shopping or mow
their lawns. There is a group of volunteers to meet almost every need. For boys who no longer have
fathers there is an organization called Big Brothers. College students and other men take these boys to
baseball games or on fishing trips and help them to know about things that boys usually learn from their
fathers. Every city has a number of clubs where boys and girls can go play games or to learn crafts.
Some of these clubs have movies or organize short trips to the mountains, the beaches, museums or
other places of interest. Most of these clubs use many high school and college students as volunteers
because they still remember the problems of younger boys and girls. Volunteers believe that some of the
happiest people in the world are those ________________________.

阅读理解     If you are a human, you can"t help but experience the time when everything seems to be going wrong
and you feel as if your life is completely out of control. It is during the low time that words of
encouragement from family, friends, coworkers or even strangers can boost your spirits.  It is also during
the low time that destructive words can be devastating (毁灭性的) and make you sink deeper and deeper into depression.
     For example, consider this story about a group of frogs who were traveling through the woods when
two of them fell into a deep pit (深坑). All of the other frogs gathered around the pit. When they saw how deep the pit was, they told the two unfortunate frogs they would never get out.
     The two frogs ignored the comments and tried to jump out of the pit. The other frogs kept telling them
to stop. Finally, one of the two frogs took notice of what the other frogs were saying and simply gave up. He died. The other frog continued to jump as hard as he could. Once again the crowd of frogs shouted at him to stop the pain. The more they shouted, the harder he jumped and finally he made it.
     When he got out, the other frogs asked him why he continued to jump when they were all shouting at
him to tell him to give up. The frog explained to them that he was a little bit deaf. He thought they were
encouraging him the whole time.
     Every time you have a chance to say either something positive or negative to another human being, do
choose the chance to say something positive! Don"t let those opportunities get away from you. Your words have a large amount of power. Use them wisely. You really never know just how much they can mean to
someone else.1. Why did the frog that succeeded in jumping to safety neglect the other frogs" comments?A. Because he would like to jump out of the pit.
B. Because he could hardly hear what the other frogs said.
C. Because he didn"t want to give up his hope.
D. Because he had a positive attitude toward life2. We can infer from the frog succeeding finally that ________.A. encouragement is not important in our lives
B. persistence is bound to victory
C. miracles sometimes happen by accident
D. success must belong to us if we keep on working3. What can we infer from the first paragraph?A. There is no way to go when we go wrong.
B. Life depends on encouragement.
C. Destructive words will lead to death.
D. Words are playing an important role around us.4. The writer mainly wants to tell us ________ in the last paragraph.A. the power of words
B. positive words
C. negative words
D. the opportunities to say something.5. Which of the following statements is WRONG according to this passage?A. The frog that made it finally thought his friends were encouraging him.
B. The frog that died finally ignored the comments and tried to jump out of the pit at first.
C. The two unfortunate frogs would never get out because they are both deaf.
D. The author advised us to choose the chance to say something positive

     Not very long ago, the computer was a strange machine. Not many people understood it. Not
many people said yes to it. Today much of that is changing. The first computer system was introduced
for use in business in the mid-1950s. Since then, the number of computer systems used in business,
government offices, and institutions has grown rapidly. In 1975, about 250,000 systems were in use
in the United States. This figure is growing by tens of thousands every year.
     The computer is an important factor in our lives. Each year we use computer more and more to
help us to collect data and to provide us with information. At one time people thought computers were
only useful to banks, department stores and governments. But today the rapidly increasing numbers of
computers are used for many other purposes. Have you ever stopped to think how you are affected
(影响) by a computer? The clothes you wear were probably made with the help of a computer. The
newspaper you read could have been edited and typed by a computer. Even radio programmes are
often prepared by computers.
     Computers today are playing important roles in education, transportation and medicine. They are
used to predict the weather, to examine the ocean, and to develop defense systems. They are being
used by businesses, governments and institutions. There is no doubt that their uses will become a greater
part of our lives.
     The influence (影响) of the computer is great. The list of its uses could go on and on. Computers
now affect millions of people in countless ways every day. 1. Before the 1950s the computer was_________.   A. widely used
B. no use at all
C. not understood by many people
D. liked by people2. The writer thinks our lives are affected by computers, but we________.     A. don"t quite notice it
B. have known it clearly
C. don"t want to know about it
D. don"t like it3. Although the first computer system was only introduced in the mid-1950s, computers now affect millions of people in countless ways every day. This means the writer___________. A. doesn"t like computers

阅读理解。     Do you ever find yourself getting really angry for almost no reason? Or suddenly feeling down
without knowing why? Going from sadness to anger to joy in a matter of minutes can make many
teens feel as though they"re losing their control. But why is the feeling of being on an emotional roller
coaster (急转突变) so common among teens?
     Dealing with constant change and pressure is part of the answer. Maybe you"re starting a new
school and not able to see old friends as much. Getting good grades or wanting to be better in sports
or other activities can be a concern for many teens. It might feel as though there just isn"t enough time
to do everything.
     Being a teen means struggling with identity and selfimage. Being accepted by friends feels
extremely important. Teens also may notice, for the first time, a sense of distance from parents and
family. You may feel you want to be on your own and make your own decisions, but it can also
seem overwhelming (压倒的) and even a bit lonely at times. As fun and exciting as this time is, it also
can be a time of confusion and conflict.
     Another important cause for mood swings is biology. When puberty (青春期) begins, the body
starts producing sex hormones. These hormones cause physical changes in the body. But in some
people, they also seem to cause emotional changes-the ups and downs that sometimes feel out of
control.
     Feeling irritable or shorttempered can be signs of depression.  So can feelings of boredom or
hopelessness. Many people think of depression as feeling sad, but depression can also bring feelings
of moodiness, impatience, anger. When depression gets in the way of enjoying life or dealing with
others, that"s a sign you need to do something about it, like talking to a counselor or therapist (治疗
专家) who can help you deal with it.
     Here are some things you can do that might make those bad moods a bit easier to handle: recognize
you"re not alone, catch your breath, count to 10, talk to people you trust, exercise, cry or wait. 1. From the passage, we can infer that the teens" emotional changes are ________.A. abnormal
B. reasonable
C. predictable
D. natural2. How many reasons does the author refer to in the passage for children"s emotional changes? A. Two.
B. Three.
C. Four.
D. Five.3. What does the passage mainly talk about?A. Why people are in bad mood.
B. What the result of depression is.
C. Bad mood can cause bad effects.
D. It"s important to be dependent.4. What does the underlined word "irritable" in the fifth paragraph mean?A. Upset.
B. Angry.
C. Unhappy.
D. Impatient.
