    Space travel is nothing new. The first spacecraft with a human was sent up into space in 1961. Since then, people have not only traveled to space, but also many of them have lived there in space stations for some time.
    The Soviet Union(前苏联) sent the first space station into space in 1971. This space station was called Salyut 1. Salyut 1 was designed as a place where people could live while they observed space and did experiments. The first group of astronauts lived there for 23 days. The Soviet Union went on to make seven more Salyut space stations. At about the same time, the United States built its own space station, called Skylab.
    Astronauts visited and often lived in these space stations for a short time. However, it wasn’t until the late 1980s when The Soviet Union sent the Mir space station that people began to live in space for a longer time. Mir stayed in space from 1989 until 2001, when it was decided that the space station was too old and no longer safe to live in.
    Living in space stations seems to be fun, but astronauts face many problems. One of them is food. All the meals on space station are put together on Earth and sent there by space shuttle. Because the food has to last a long time (sometimes up to three months), a lot of it has to be stored in cans. The space station does not have a fridge, but it has a cool room to keep fruit and vegetables fresh. Astronauts also eat many other foods such as dried meat that do not need special care.
    Without the help of gravity, sitting down to eat can be tough. Astronauts sometimes have to fix themselves to the wall while eating. They also have to be very careful to that food does not float away.
    小题1:Which of the following has the closest meaning to the underlined word “observed” in Paragraph 2?
    A．DiscoveredB．CheckedC．WatchedD．Fixed
    小题2: What can we infer(推断)from the passage?
    A．Astronauts can never have a chance to eat fresh food when they live in space station.
    B．The Soviet Union sent a total of 9 space stations into space in the 1970s and 1980s.
    C．Astronauts could live in the Mir space station for no more than three weeks.
    D．Space travel has quite a long history of more than 60 years.
    小题3:What is the best title of this passage?
    A．Exploring SpaceB．Space TravelC．Living in SpaceD．Space Stations

    小题1:C
    小题2:B

    Gao Wenqi, 49, owner of a restaurant in Xi'an, Shanxi, started to offer a new service on April 13, 2013: suspended meals (待用快餐). Now many restaurants in China, such as in Henan,Chongqing and Yunnan, have joined the program.
    You can pay 10 yuan for a meal, which should be sold at 16, and leave it at the restaurant. Then other people in need, such as the disabled（残疾人）， the poor elderly or homeless children,can have it without paying.
    This idea comes from the cafes (咖啡馆) in Naples, Italy. It's a tradition that someone there pays in advance for an extra (额外的) cup or two. Then another coffee-drinker can take them for free.
    “The program is meaningful. It offers help with dignity（尊严），” said Gao to Xinhua. However, people are worried that someone who is able to pay would also ask for the suspended meals, so there should be rules for this program.

    阅读短文，根据所读内容在短文后图表中的空格里填入一个恰当的单词
    Trees should be pruned(修剪)when it is necessary. A good gardener will cut away the overgrown and unwanted branches(树枝). They can make the trees more beautiful and healthier. But sometimes we’d better leave the trees to grow in their own way. Because the inexperienced gardeners will damage(毁坏) the trees.
    First, pruning may be done to make sure that trees in good shape or size. Maybe people want to get a tree of the right height and at the same time to help the growth of small side branches. Then people can make the tree’s appearance thick or give it a special shape.
    Secondly, pruning may be done to make the tree healthier. You may cut out diseased or dead branches. The health of a tree may be encouraged by removing branches that are blocking up (封闭)the center and so stopping the free movement of air.
    One result of pruning is that an open wound is left on the tree and this provides an easy chance for disease, but the wound will heal(愈合). Often there is a race between the healing and the disease as to whether the tree will live or die, so that there is a period when the tree is in danger. Every gardener should try to reduce that danger of death as soon as possible. It is important to make the area, which has been pruned, smooth and clean, because healing will be slowed down by roughness(粗糙). You should allow the cut surface to dry for a few hours and then pain it with one of the special materials. Pruning is usually done in winter, because you can see the shape of the tree clearly and also it is very unlikely(未必的) that the cuts you make will bleed. If this happens, it is impossible to paint them properly(合适地).

    For thousands of years, people have used plants to make medicines. They used different parts of the plants —the roots, the leaves, the flowers, and the bark (树皮). Today, doctors have rediscovered more medicinal (药用) values of some plants. Let’s look at some examples.
    Foxglove is a common plant. People have used it to make the heart slow down. Recently scientists have developed another drug from it. This new drug helps prevent other heart problems.
    In some areas, malaria has been a problem. Scientists have learned that the bark of a South American tree, the cinchona, can be made into a drug to prevent malaria. For a long time, the Chinese have known that a special plant, wormwood, can also fight malaria. Scientists have been working with it to develop new drugs against malaria.
    In Germany, some scientists studied garlic (大蒜) for four years. They found that it helps prevent the build-up of plaque (血小板) because too much plaque is bad for health. This very common plant continues to be studied.
    As we know, there are about 250,000 kinds of flowering plants in the world. Scientists have only studied little more than one percent of plants for their medicinal value. Maybe medicines for AIDS and cancer will be made from the other 99 percent.
    小题1:What can foxglove be used for?
    A．Studying plants.
    B．Building up the plaque.
    C．Treating AIDS and cancer.
    D．Preventing heart problems.
    小题2:What does the underlined word “malaria” in Paragraph 3 refer to (指的是)?
    A．A drug.B．A plant.
    C．An illness.D．An animal.

    You can easily find that your sister or brother is different from you. You live together in the same house and have the same parents, but you have different personalities(性格).
    Why? One possible reason is the way your parents treat you.
    Firstborn children receive all the attention from their parents. Generally speaking, a firstborn has twice as many photos as any other child has. Parents usually give firstborns more responsibilities (责任)and depend on them to take care of younger brothers and sisters. As a result, firstborns are often responsible, hard-working, and serious. They often want to do well at school and in work. More firstborns became American Presidents, for example George W.Bush, George Washington and Lyndon Baines Johnson, than second or last-borns.
    When a second child arrives, parents are more relaxed. The second child has to compete (竞争)with the first-born for parents’ attention and love. These children often choose different sports and hobbies to develop different personalities. They are often outgoing, but can be jealous and get angry easily.
    The youngest child is usually the happiest, and has fewer responsibilities and more freedom(自由的). These children do well at school and in work, but have to be creative（创造性的） to get their family’s attention. They are often friendly and cool. Many famous talk-show hosts were born last.

    Every year landslides cause 25 to 50 deaths and $2 billion in damage in the United States. And in December, a single event killed more than 2000 people in the Philippines. Sending workers to stabilize mountainsides using steel bars can help a lot, but it introduces new difficulties because of dust and loosen heavy, dangerous debris from the work. “It’s a quite dangerous job,” says Giorgio Pezzuto of D’ Appolonia, working with eight other companies. Now there may be an answer: a three-ton robot called Roboclimber.
    “The idea is to operate a machine far away that can do the stabilizing job without a human being near,”says Pezzuto, manager for the project, which is supported by a European organization. Engineers say that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged spider, has cost at least $2 million so far. It should be able to climb mountainsides, drill holes and insert steel bars there. Testing should begin in May.
    小题1:The underlined word “event” refers to_____
    A．earthquakeB．debrisC．dustD．landslide
    小题2:The purpose in writing this text is _____
    A．to tell people how serious the damage caused by landslides is
    B．to tell people that sending workers to stabilize mountainsides is a dangerous job
    C．to show people how to use a new robot
    D．to introduce a new robot that can be used to stabilize mountainsides
    小题3:What does the robot look like?
    A．human beingB．spiderC．steel barD．a drill
    小题4:A landslides cause _____________in damage in the United States Every year .
    A．25 to 50 deathsB．more than 2000 people died
    C．$2 billionD．both A and C
    小题5:The biggest advantage of this product is that____
    A．it will be faster and cheaper than manual labor
    B．it can climb mountainsides, drill holes and insert steel bars there.
    C．it can do the stabilizing job without human beings near
    D．it is like a spider
