Farmer Ed Rawlings smiles as he looks at his orange trees. The young oranges are growing well in Florida's weather. Warm sunshine and gentle rains, along with Ed Rawlings' expert care, will produce a good crop of oranges this year.
  But Ed has to fight against Florida's changeable winter weather. In January and February, temperatures can destroy Ed's entire orange, crop. Having farmed in Florida for the past 35 years, Ed Rawlings is prepared for the frosts(霜). When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer (層)of ice on the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm.
  What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is sucked in by the fruit and keeps its temperature at a safe level. Ed Rawlings has effectively used this method(方法)to save many orange crops.
  But Ed still faces some difficulties. The trees should be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity of water must be used. Too much water can form a thick layer of ice that will break the trees' branches. Another difficulty is that wind blows away the heat. So Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used.
  Computer technology may help Ed Rawlings with some of these worries. With equipment, air and soil temperatures and wind speed can be measured. The information is fed into a computer which can tell when temperatures drop to freezing. The computer can correctly decide the quantity of water to be used and how frequently the trees should be watered. Ed Rawlings will find looking after his orange trees a lot easier with the help of a computer, and we'll all have the benefits(or advantages)of computer-age oranges.

    It is true that a smile means the same thing in any language. So does laughter or crying. There are also a number of clear similarities in the way different animals show the same feeling. Dogs, tigers and humans, for example, often show their teeth when they are angry. This is probably because such behavior patterns are inherited (遺傳) rather than learned.
  Fear is another emotion that is shown in much the same way all over the world. In Chinese and in English literature, a phrase like “he went pale and begin to tremble (顫抖)”suggests that the man is either very afraid or he has just got a very big shock. However, “he opened his eyes wide” is used to suggest anger in Chinese whereas in English it means surprise. In Chinese surprise can be described in a phrase like “they stretched out(伸出)their tongues”! Sticking out your tongue in English is an insulting(侮辱)or expresses disgust.
  Even in the same culture, people differ in ability to understand and express feelings. Experiments in America have shown that women are usually better than men at recognizing fear, anger, love and happiness on people’s faces. Disgust, contempt (蔑視) and suffering seem to be the most difficult emotions for people everywhere either to recognize or to express. Other studies show that older people usually find it easier to recognize or understand body language than younger people do. And psychologists (心理學(xué)家) such as E.G. Beier have also shown that some people often give the completely impression of how they feel. For example, they try to show love but in fact communicate dislike. Or when they want to show interest, they give the impression that they don’t care. This can happen even among close friends and members of the same family. In other words, what we think we are communicating through language, voice, face and body movements may be the exact opposite of what for people understand.
71.According to the passage, even in different cultures the most easily recognized emotion is    .
A.a(chǎn)nger       B.dislike      C.happiness  D.surprise
72.Experiments show that easier understanding of words and gestures has something to do with your           .
A.a(chǎn)ge and sex             B.love and cultural differences
C.impressions about the speaker D.emotional state
73.When we communicate with people,        .
A.we know exactly what they mean while they express their emotions
B.we sometimes misunderstand each other
C.we usually mislead them by expressing the opposite of our feeling
D.it seems much mere difficult to understand body language than language
74.Which of the following statements is NOT true according to the passage?
A.When we communicate our real emotions, we many cause misunderstanding to others.
B.Different people in different cultures may have different ways to understand one gesture.
C.Some people are likely to hide their real feelings and express them in the opposite way.
D.What we say does always mean the same thing as the gestures we make.
75.The underlined word “disgust” in Paragraph 2 probably means “     ” in this passage.
A.strong dislike   B.friendliness      C.love  D.sickness

WHAT can help you make a fortune in the future? Graduating from a top university might not be enough.A new study from the University of Essex in Britain has shown that the more friends you have in school, the more money you’ll earn later.
The idea that popularity could have a serious impact on one’s earning potential shouldn’t come as too much of a surprise.The researchers noted that if you want to get_ahead in life, social skills and networking are easily as powerful as talent and hard work.
“If a person has lots of friends, he or she has the ability to get along with others in all kinds of different situations,” said Xu Yan, 17, from Nantou High School in Shenzhen, who totally agreed with the recent finding.“Also, friends always help each other.They not only create wider social circles for you but lift your mood when you occasionally feel depressed.” She believed that all this helps you “earn a higher salary”.
Maybe that’s why some people think the younger generations are in the age of Friendalholism (交友狂癥).A woman even complained that the networking website Facebook’s 5000-friend limit was too low for her large reserve of social contacts.
But Meghan Daum, who works with The Los Angeles Times in the US, disliked the idea that quantity trumps (勝過) quality in the age of Friendaholism.“Call me uncool, but I think of a friend as an actual person with whom I have an actual history and whom I enjoy actually seeing.” said Daum.She admitted that some Internet social networkers just want to get as many of not-really-friends as possible.Although she agreed that social ties grease (潤(rùn)滑) the wheels of life, she also warned, “Finding a real friend is something that really matters.”
63.What CANNOT be learned about friends from the passage?
A.They enlarge social circles for you.
B.They offer encouragement when you are upset.
C.Only talented friends help you to earn success.
D.Friends enable you to overcome difficulties.
64.In the age of Friendalholism, ________.
A.there are networking websites to help people make friends
B.a(chǎn) person with popularity is sure to enter a top university
C.facebook helps social networkers make as many friends as possible
D.there are always more not-really-friends than actual ones
65.The underlined words probably mean ________.
A.expect      B.struggle    C.graduate   D.succeed
66.Meghan Daum holds the attitude towards making friends that ________.
A.a(chǎn)ctual friends outweigh not-really-friends
B.the more friends one has, the better
C.friends can help make a big fortune
D.social relations can hardly make one’s life better

Marriages improve after children grow up and move out,according to an academic study,
which suggests an“empty nest”is not always a bad thing.
Popular wisdom has it that parents’relationships may suffer once their young fly the coop,
because they feel they have lost their purpose in life.However,a new study by researchers at the
University of California,Berkeley,has found that many couples actually feel happier when their
children leave home because they are able to enjoy spending time together.
In total,123 American mothers born in the 1930s were tracked for 18 years and asked to rate
their satisfaction levels shortly after marrying,when they were bringing up babies,once their
children reached their teenage years and finally at age 61,when almost all had“empty nests”.
Although not all said they were happier in general,most claimed their marriages had improved since their children had left home.Researchers believe this is not just because the spouses were spending more time together,but because they were able to enjoy each other’s company more.
One of the participants in the study,which is published in the jourmal Psychological Science,
said:“Once the kids grow up…there’s some of that stress removed…that responsibility removed,so things are a little more relaxed.’’
Psychologist Sara Gorchoff,who carried out the investigation,said:“The take-home message
for couples with young children is‘hang in there’.”Her co-author Oliver John added:“Don’t wait until your kids leave home to schedule quality time with your partner.”   
However,Dr Dorothy Rowe,from the British Psychological Society,said the effects of living
in an“empty nest'”will depend on the parents’relationship with their children.“If yod’re just
waiting for them to leave home so you Can get on with your life,then of course you’11 be pleased to see them go,”she said,‘‘But if you’ve built your life around your children you’11 be terribly lonely.”For some parents,their world falls apart when their Children leave.’’
72.It is commonly believed that            
A.marriages improve after children leave home
B.a(chǎn)n“empty nest'’is always a happy thing
C.parents’relationships may suffer once their young grow up and move out
D.parents will be pleased after their children leave home

A.At age 61.when almost all had“empty nests”.
B.Shortly after marrying.
C.Once their children reached their teenage years.
D.When they were bringing up babies.
74.Marriages improve after children fly the coop not because         
A.many couples are able to spend time together
B.many couples arc able to enjoy each other’s company
C.things are a little more relaxed

People have always had to find ways to keep food safe to eat. Methods to dry, smoke and salt food were invented thousands of years ago. The process of canning is much more recent. This storage method keeps food safe to eat for long periods of time. Today, canning is one of the most popular methods of storing food.
Canning uses heat to kill bacteria and other micro-organisms that cause poisons to form in food. Canning also takes away the air that these organisms need to live. One popular method of canning uses a water bath.
Clean fruits or vegetables are placed in glass bottles. The food can be put into the bottles either hot or cold. The cold method is used for soft fruits and vegetables that could lose their shape or taste. Firmer fruits and most vegetables are usually cooked. They take up less space in the bottles. After the food has been placed in glass bottles, boiling water is poured into the bottles to about three centimeters below the top. Then covers are placed on the bottles, but are not turned all the way. The bottles are placed in a large container filled with warm water that is then brought to a boil. The water must completely cover the bottles, from three to five centimeters over the top. When the water boils, any air in the bottles will be expelled. The boiling continues for several minutes. Then the bottles are allowed to cool. Finally, they are placed briefly into cold water. This makes a strong barrier to keep the air out. In other words, a vacuum is created. When the bottles are completely cool, notes can be placed on them to identify what is inside. The bottles can then be stored in a cool, dark place at a temperature of between four and twenty-one degrees Celsius.
Canning allows your family to enjoy foods that might not come fresh throughout the year. It is also a good way to store food for six months to a year, or even several years, in case of an emergency. It does not cost much to continue canning every year once the equipment has been purchased.
You can get more information about canning food from the group, Volunteers in Technical Assistance. VITA is on the Internet at vita.org.
55. Which of the following is the right order of canning food?
a. put bottles in warm water.          b. place notes on the bottles.
c. place bottles briefly into cold water  d. pour boiling water into bottles
A. d a c b   B. a b c d    C. b d c a   D. a d c b
56. According to the text, which of the following is right?
A. The way to can food has been found by ancient Chinese.
B. Canning uses water to kill bacteria.
C. Hard fruits are suitable for cold method.
D. The boiling water will take away the air in the bottle.
57. What does the word “vacuum” mean in the – paragraph?
A. a missing situation   B. a gap   C. an enclosed space without air  D. a hole
58. what’s the best title of the text?
A. The advantages of canning food.
B. Canning food and health.
C. Put fruits and vegetables into cans.
D. How to make canning food.

C

       The words “timetable” and  “schedule” make most final year students want to eat their own vomit(嘔吐物). Unfortunately, the harsh reality is that final year students must develop a timetable. If you don’t have a schedule or plan for studying ,you will have no way of allocating your valuable time when the unexpected arises. A well-thought-out timetable can be a lifesaver . It is up to you to learn how to develop a schedule that meets your needs .Change it if necessary ,but most important ,follow it . All timetables should be made with the idea that they can be changed. A good one will keep you from wandering off course.
A good timetable should make every hour count—every class ,social event and other activity you engage in .You must focus on the other “free time” available and how you will use it .Make a weekly schedule and divided each day into one-hour increments .Indicate times for classes ,socializing ,and work time. Also block off a period for sleeping every day. In the precious hours left over ,plan time for study .This gives you a rough road map of the time available. Of course ,you can change your schedule as circumstances need.
The timetable you develop should guide you in how to distribute the available time in the most productive manner .Sticking to your schedule can be tough ,but don’t dribble away valuable time. Avoiding study is the easiest thing in the world .It is up to you to follow the schedule you’ve prepared .A good deal of your success in high school and with any future study depends on this simple truth.
Remember ,there is a learning curve. You learn the most in the first 30 minutes of study; after that ,it progressively deteriorates(減弱). After four or five hours of studying the same material in the same way, you are learning virtually nothing. The solution is to keep switching subjects and study styles.
64.What is the best title of the passage?
A.Advantages of starting a timetable         B.Keep to it ,and you will succeed
C.Make a schedule ,and follow it             D.Learn to love your timetable
65.What does Paragraph 2 talk about?
A.Tips for making a schedule.                  B.Significance of a scientific timetable.
C.Requirements for making a timetable.    D.Importance of following one’s schedule.
66.The following are characteristics of a good timetable EXCEPT that    .
A.it can be changed                                 B.it is flexible
C.it is of many periods                            D.it can save our time
67.From this passage ,we can learn if we wish to achieve high learning efficiency, we’d better    .
A.shift subjects and use different methods regularly
B.devote to the same material continuously
C.turn to teachers for help if necessary
D.have a break every thirty minutes
