If you feel at present that you don’t have enough friends in your life, one reason may be that you have let yourself become too busy to make time for the relationships you already have. Starting and keeping friendship requires effort and commitment.
Many of us let our lives become so busy with work and other commitments that we don’t get around to scheduling time for pleasure and renewal（叙旧）with the friends, relatives and acquaintances we already have.
Making the effort to call your friends more regularly and to accept more of the invitations you receive from others can improve your social life in a hurry!
Are there any people you could call right now and be assured of a pleasant welcome? Are there people that you could count on to help you in time of difficulty? Can you have close talks with them? Do you have fun when you are together? Are you happy to have them in your life?
If you haven’t seen much of them lately, is it because you have become too busy? Have you grown apart? Was there an argument?
If the main reason you haven’t been getting together with the people you already know is that you have got too busy, take a good look at how you spend your time. Compare it with your real values and priorities（优先考虑的事）in life. Is your busy lifestyle really bringing you the quality of life that you want?
If you have become too busy for friends, why has this happened? Are you seeking material toys in your life at the expense of relationships with other human beings? Have you allowed your time to be over-committed because you never say “No” to anyone? Do you insist on doing things yourself that could be appointed to others? If so, why? Do you believe that everything depends on you?
Examine whether the way you are now spending your time accurately reflects your deepest values and priorities. Make sure that you schedule adequate time for the things that are truly most important to you.
If you really want to keep friends in your life, make a space in your schedule, and a space in your heart for them.

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda（大熊猫）eats only one particular type of bamboo（竹子）. Other animals eat only one type of food even when given the choice. A kind of white butterfly（蝴蝶）will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet（多样化饮食）. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life. 60. We can infer from the text that humans and animals _________.
A. depend on one sense in choosing food B. are not satisfied with their food
C. choose food in similar ways D. eat entirely different food
61. Which of the following eats only one type of food?
A. The white butterfly. B. The small bird. C. The bear. D. The fox.
62. Certain animals change their choice of food when ___________.
A. the season changes B. the food color changes
C. they move to different places D. they are attracted by different smells
63. We can learn from the last paragraph that __________.
A. food is chosen for a good reason B. French and British food is good
C. some people have few choices of food D. some people care little about healthy diet
There are warm tropical regions all over the globe, but only the Indians of the South American rain forests have formed the habit of sleeping in the open air. Long before they made painful acquaintance (相识) with Europeans, they had invented something that was unique on earth: the hammock.
Nobody really knows who first had the bright idea of making sleeping in the air the symbol of untroubled rest. The Indians see the hammock as a “gift of heaven (上天)”, something given to them a very long time ago.
In it the Indians pass away hot noon hours, napping or chatting. Swinging it to and fro (来回摆动) creates a cooling breath of air and keeps away insects. They work and play in hammocks, are born and die there.
Hung like a suspension bridge between heaven and earth, a hammock is dry while the soil is damp and is safe from most wild animals.
Hammocks have the advantage over beds in that they are easy to transport and take up very little space when they have been rolled up(卷起) . Indians never go on a journey without their hammocks, not even to their plantations.
76.The word hammock in this passage means _______.
A. a suspension cage which can be swung to and fro in the air
B. a seat hanging by two ropes from the branch of a tree
C. a suspension bridge in the South American rain forests.
D. a net hung between two supports and used as a bed.
77. When was the hammock invented and by whom?
A. The Indians had invented the hammock long before they came to South America.
B. The Indians had invented the hammock long before the Europeans came to South America.
C. The Europeans invented the hammock after they made acquaintance with the Indians.
D. The Europeans had invented the hammock before they went to South America.
78. Indians swing the hammock to_______.
A. pray to heaven for a gift B. keep away flies, mosquitoes and other insects
C. keep away wild animals D. all asleep quickly
79. According to the passage, hammocks _______.
A. cannot be rolled up B. are difficult to transport

The tea gardens in Sri Lanka are actually large estates(种植园). The best tea usually comes from plants grown on high grounds, the cool hilltops with rows and rows of tea plants. The plants are about one metre apart. The plant is often pruned so that it remains only 60 to 90 centimetres high. Pruning is important because it encourages the growth of tender shoots, or young leaves. It is from these shoots that the best tea is got.
Practically all the tea pickers are women. The estates prefer to employ women pickers because they are more careful. Their thin fingers can easily remove the twin leaves and new shoots from the plant, which are the parts used for processing(加工) tea. The pickers carry large baskets into which they throw their pickings. A skilled worker can harvest between 9 to 14 kilogrammes of tea leaves a day. Usually new shoots can be picked from the plants about every ten or fifteen days.
Processing tea shoots into the familiar dry tea leaves requires great care and skill .There are various methods of processing depending on the type of tea required .For black tea ,the young green leaves are first spread out o shelves to dry. This process removes much of its water and the leaves become soft. After this ,the leaves are passed through heavy rollers .This operation will press the leaves for juices which give the tea both its colour and taste .Then the leaves are spread out on floors and left to ferment （发酵）under wet conditions. Fermentation develops the rich taste of black tea .The fermented leaves are then dried with a hot-air blower until they become rolled-up black leaves .The final step is to sort and grade them before the black tea is ready for sale to countries all over the world.
68.In the first paragraph ,the word “pruning” means .
A.regular cutting of the plants B.frequent watering
C.regular use of chemicals D.growing the plants high in the mountain
69.One of the reasons why women are employed to do the picking is that .
A.they work harder than men do in the picking
B.they can throw their pickings more easily into the baskets
C.their fingers fit them better for the job.
D.they can more easily find the twin leaves.
70.How many processing steps are mentioned in the last paragraph?
A.Three. B.Four. C.Five. D.Six.
71.What is the writer’s purpose in writing the passage?
A.To introduce various methods of tea processing.
B.To persuade readers to buy tea from Sri Lanka.
C.To tell a story that had happened in the tea gardens.
D.To inform readers of tea growing ,picking and processing.
At Dallas/Fort Worth Airport, the lights are controlled by sensors that measure sunlight. They dim immediately when it's sunny and brighten when a passing cloud blocks the sun.
A wall of windows at a University of Pennsylvania engineering building has built-in blinds (百叶窗) controlled by a computer program that follows the sun's path.
Buildings are getting smarter -- and the next generation of building materials is expected to do even more.
Windows could catch the sun's energy to heat water. Sensors that measure the carbon dioxide breathed out by people in a room could determine whether the air conditioning needs to be turned up.
Many new materials and technology have been designed in the last 15 years. They now being used in a wave of buildings designed to save as much energy as possible. They include old ideas, like "green roofs," where a belt of plants on a roof helps the building keep heat in winter and stay cool in summer, and new ideas, like special coating for windows that lets light in, but keeps heat out.
As technologies such as sensors become cheaper, their uses spread.
The elevators (电梯) at Seven World Trade Center, which is under construction in New York, use a system that groups people traveling to nearby floor into the same elevator, thus saving elevator stops. People who work in the building will enter it by swiping (刷) ID cards that will tell the elevators their floor; readouts will then tell them which elevator to use. The building also has windows with a coating that blocks heat while letting in light.
More new building materials and technology are in development. A Philadelphia building firm is now working on "smart wrap" that uses tiny solar collectors to catch the sun's energy and transmitters (传输器) the width of a human hair to move it. They are expected to change the face of the construction industry in the next ten years or so.
72. ______ will be developed and used in the construction industry.
A. "Green roofs" that cool or heat buildings
B. "Smart wrap" that catches the sun's energy
C. Sunlight-measuring sensors that control lights
D. Window coating that lets light in, but keeps heat out
73. The elevators at Seven World Trade Center are special because they can ___
A. send people to floors with fewer stops
B. teach people how to use their ID cards
C. make people stay very cool in summer
D. help people go traveling in the building
74. The underlined word “it” in the last paragraph refers to _____.
A. a human hairB. smart wrap
C. the sun's energyD. a transmitter
75. What might be the most suitable title for the text?
A. Buildings Are Becoming Smarter
B. Buildings Are Getting More Sunlight
C. Buildings Are Lacking in Much Energy
D. Buildings Are Using Cheaper Materials
Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all ,you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However ,they sing most of the time for a very different reason .Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a “territory” is? A territory is an area that an animal ,usually the male, claims（声称）as its own .Only he and his family are welcome there .No other families of the same species（物种）are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.
If so, you have actually scared the stranger away without having to fight him .A bird does the same thing. But he expects an outsider almost any time ,especially at nesting（筑巢）season. So he is screaming all the time, whether he can see an outsider or not .This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
You can see that birds have a language all their own. Most of it has to do with attracting mates and setting up territories.
56．Some scientists believe that most of the time birds’ singing is actually .
A．an expression of happiness B．a way of warning
C．an expression of anger D．a way of greeting
57．What is a bird’s “territory”?
A．A place where families of other species are not accepted.
B．A place where a bird may shout at the top of its voice.
C．An area for which birds fight against each other.
D．An area which a bird considers to be its own.
58．Why do birds keep on singing at nesting season?
A．Because they want to invite more friends.
B．Because their singing helps frighten outsiders away.
C．Because they want to find outsiders around.
D．Because their singing helps get rid of their fears.
59．How does the writer explain birds’ singing?
A．By comparing birds with human beings.
B．By reporting experiment results.
C．By describing birds’ daily life.
D．By telling a bird’s story.
