In 1971 a young man who grew up very poor was travelling across the country, trying to make a new start for himself.Along the way he had completely run out of（用光） money and was forced to spend the night in his car.This continued until one morning, after a week of sleeping in his car, he walked nervously into a restaurant and ordered a big breakfast.
After eating his first good meal in weeks, he found himself lying to the waiter, telling him he had lost his wallet.The waiter, who was also the owner, walked behind the chair where the young man had been sitting.He bent down, and came up with a $20 bill that looked as if it had fallen on the floor and said, “Son, you must have dropped this,” the owner said.The young man couldn’t believe his luck! He quickly paid for the breakfast, left a tip, bought gas with the change, and headed West.
On the way out of town, he began to understand what the owner did.Maybe nobody dropped the money at all.“Maybe that fellow just knew I was in trouble and he helped me in a way that didn’t embarrass(使尴尬)me.So I just made a promise to help other people if I can.”
Later, he worked very hard and became a rich man.Now he lives near Kansas City.Each year he gives away thousands of dollars.He is known as the “Secret Santa” because at Christmas time each year, he personally hands money out to those on the street and at restaurants.Last year, he gave more than $50,000 away in Kansas City.The young man was travelling cross the country in 1971 to______.
| A．look for a good restaurant | B．improve his life |

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

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.

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

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.
Walk through the Amazon rainforest today and you will find it is steamy, warm, damp and thick. But if you had been around 15,000 years ago, during the last ice age, would it have been the same ?For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted（反应）to the cold ,dry climates of the ice ages ,but until now ,no one has reached a satisfying answer.
Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming . Currently the trees in the Amazon take in around 500 million tons of CO2 each year; equal to the total amount of CO2 giving off in the UK each year. But how will the Amazon react to future climate change? If it gets drier ,will it still survive and continue to draw down CO2 ?Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.
Unfortunately ,getting into the Amazon rainforest and collecting information are very difficult .To study past climate ,scientists need to look at fossilized pollen ,kept in lake muds .Going back to the last ice age means drilling deep down into lake sediments （沉淀物）,which requires specialized equipment and heavy machinery .There are very few roads and paths ,or places to land helicopters and aeroplanes .Rivers tend to be the easiest way to enter the forest ,but this still leaves vast areas between the rivers completely unsampled（未取样）.So far ,only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.
64．The underlined phrase “mopping up” in the second paragraph means .
A．cleaning up B．taking in C．wiping out D．giving out
65．How will the Amazon rainforest react to future climate change?
A．It’ll get drier and continue to remove CO2 .
B．It’ll remain steamy ,warm ,damp and thick .
C．It’ll get warmer and then colder and drier.
D．There is no exact answer up to present.
66．What’s the main idea of the last paragraph?
A．It’s important to drill deep down into lake sediments to collect information.
B．It’s impossible to prove how climate changes in the Amazon rainforest.
C．It’s hard to collect information for studies of the past climate in the Amazon rainforest.
D．It’s necessary to have specialized equipment and machinery to study the past climate.
67．The best title for this passage may probably be .
A．Studies of the Amazon B．Climates of the Amazon
C．Secrets of the Rainforests D．Changes of the Rainforests
You either have it, or you don’t—a sense of direction, that is. But why is it that some people could find their way across the Sahara without a map, while others can lose themselves in the next street?
Scientists say we’re all born with a sense of direction, but it is not properly understood how it works. One theory is that people with a good sense of direction have simply worked harder at developing it. Research being carried out at Liverpool University supports this idea and suggests that if we don’t use is, we lose it.
“Children as young as seven have the ability to find their way around,” says Jim Martland, Research Director of the project. “However, if they are not allowed out alone or are taken everywhere by car, they never develop the skills.”
Jim Martland also emphasizes that young people should be taught certain skills to improve their sense of direction. He makes the following suggestions:
●If you are using a map, turn it so it relates to the way you are facing.
●If you leave your bike in a strange place, put it near something like a big stone or a tree. Note landmarks on the route as you go away from your bike. When you return, go back along the same route.
●Simplify the way of finding your direction by using lines such as streets in a town, streams, or walls in the countryside to guide you. Count your steps so that you know how far you have gone and note any landmarks such as tower blocks or hills which can help to find out where you are.
Now you need never get lost again!
