E-book is short for electronic( 电子的) book. It is usually read on personal computers. Some
mobile phones can also be used to read e-books.
Earlier e-books were written for a specific group of readers and were about only a few subjects. With the development of the internet, knowledge and answers to a lot of questions mainly come from e-books. This is why the e-book business is increasing quickly
E-books have many advantages. First, they save time. We don’t need to go to a bookstore to buy books, besides, we can find the topic we want to know about on the Internet, and then we can quickly get many e-books on similar topics. Second, e-books save money. Some e-books cost a little money, and there are millions of e-books on the Internet that we can get for free. Third, more trees are saved because e-books don’t need to be printed(印刷) on paper. Fourth, e-books make reading more convenient. You can carry a whole library of hundreds of books with you in a small computer or any e-book reader (电子阅读器) without worrying about their weight.
But e-books have certain disadvantages. They need a personal computer or an e-book reader and the information can be lost if its file format (文件格式) is not supported or changed in the reader’s computer.
However, e-books provide us with a new way of reading. That is good.

Robots seem new to most people, but they have a long history. one was made by a Greek.
The robots in the films are usually stronger, and cleverer than people. In real life, most robots are used in factories. They are used to do many dangerous, difficult or boring . Some people can’t look after and robots can help them. For example, some people can’t see, and they use dogs themselves move around. This kind of dog is called a guide dog (导盲犬). But now scientists are making robots help them. In the future, robot dogs take the place of (代替) these guide dogs.
Today robots are used in American hospitals. In the hospital, a robot meals from the kitchen to the sick people’s rooms. It never lost its way because it has a of the hospital in its computer system(系统).

Plant scientists consider them as fruit. Most other people think of them as vegetables. Whatever you call tomatoes, there are many different kinds of this popular and healthy food.
There are two groups of the plants. Small tomato plants grow to about one meter. They can be planted rather close together. Some short kinds do not require special care and are often gotten crop by machines. Large tomato plants can grow over two meters tall. They also produce larger fruits.
People who grow only a few plants can place wire cages around each one. The cage can be made of wire fence material. The cage helps the plant grow taller and produce a better crop.
Tomatoes often need extra calcium (Ca), or the fruits may be ruined. Add lime to the soil can solve this problem. Dry lands may also ruin the fruits. Tomatoes need water regularly. The soil should never dry out completely. Dried grass or leaves placed around the plant can help hold water in the soil and stop the growth of unwanted plants.
Tomatoes are native to South America. The tomato is a member of the potato family. The leaves of the plant are poisonous, like the leaves of its relatives. Before the 18th century, people grew tomatoes only as pretty plants. They called the bright red fruit a “love apple”, but would not eat it.Which of the following is right about the small tomato plants?
A. They can grow to about 2 meters.
B. They can’t be planted close together.
C. Some of them don’t require special care.People place wire cages around the plant in order to ___________.
A. protect the plant from being taken by others.
B. help the plant grow taller and produce a better crop

C. putting dried grass around the plant What can we learn from the passage?
A. Tomatoes are native to North America.
B. The leaves of the plant can also be eaten.
C. Americans began to eat tomatoes from the 18th century.
Scientists are placing robotic dogs in the homes of lonely old people to test whether they can improve the quality of life for humans. Alan Beck, an expert(专家) in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study on the effect of robotic dogs on old people’s depression (沮丧) , physical activity, and life satisfaction.
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data(数据) for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I’m watching TV, he’ll stay in my arms until he wants down. He has his own mind.”
The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate(与……相关) to the robotic dog, because it was metal and not furry.” Beck says. “Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels or heart rhythms(心律). AIBOs may even one day have games that can help stimulate(刺激) older people’s minds.”The purpose of Beck and Edwards’ study is to _____________.
| A．understand human-animal relationship |
| B．make lonely old people’s life better |
| C．find the causes of old people’s loneliness |
| D．improve the animal-assisted research |
In the research, the old people are asked to _____________.
| A．note the activities of AIBOs |
| B．keep AIBOs at home for 12 weeks |
| C．record their feelings and activity |
| D．study the collected information |
What does the underlined word “removes” mean?
| A．moves again | B．is movable | C．doesn’t need | D．need |
What is the better point of AIBO than live dogs?
| A．It is easier to keep at home. |
| B．It can help the disabled people. |
| C．It responds to all the human orders. |
| D．It can watch TV with its owner. |
The writer seems to suggest that the future robotic dogs may__________.
| A．cure certain diseases | B．keep old people active |
| C．change people’s ideas | D．look more like real dogs |
It is said that another acre of the world’s forest will be destroyed forever. Why is this happening? There are two reasons — land and wood. In many countries the trees have been cut down because the land was needed for animals or crops. In other parts of the world the trees are cut down because their wood is wanted. This wood is used by local people for firewood or it is used for building. But many people don’t know that in most places the trees won’t be replaced. The soil in the forests is very thin, but it is protected by the trees. When the trees are cut down, the soil is washed away by the rain or blown away by the wind. Soon nothing can be grown on it. The forest becomes a desert. Then more land will be needed, and more trees will be cut down.
When the forest is destroyed, it isn’t only the trees that are lost — the homes of millions of animals and plants are destroyed, too. All kinds of animals are in danger — fish，reptiles, birds, mammals, insects, and shellfish — as well as thousands of plants.
Who is to blame for this? The answer is simple: all of us. There are just too many people in the world. The world’s population is now six billion. Of course, it’s very easy to blame the local people. We don’t cut down trees. They do. But the products are bought by people like you and me — wood houses, beds, tables, chairs, paper… Why are the forests being destroyed? Just look around. You are probably using it right now. People cut down large areas of trees in order to _________.
| A．grow crops | B．keep animals | C．build houses | D．get land and wood |
In most places, __________after trees are cut down.
| A．new trees can grow better | B．forests will become deserts |
| C．most animals can live there | D．people build new house there |
According to the passage, we should _________________ to protect the forest.
| A．use fewer wood products | B．plant more trees |
| C．blame the local people | D．protect the soil |
In 1988，Wang Chengbang retired（退休）from the army.Instead of enjoying a relaxing life，he volunteered to save the soil from desertification（沙漠化）by planting trees in Korla，Xinjiang.
It is no easy job.The high temperature in Korla makes it difficult for anyone to work day after day in the sunshine.Besides，water is a big problem.In fact，Wang Chengbang's work in the first few years failed as very few trees survived（存活）.
But Wang Chengbang would not give up."After trying many different ways，I have learned how to grow young trees in a better way，" said Wang Chengbang.He also worked out new ways to save water.With his hard work，more and more trees have survived.So far，he has planted more than 1.5 million trees.Those green trees prevent desertification，make the air cleaner and protect people from the hot sun.Now，Korla is a model city in environmental protection.
Wang Chengbang is also successful in fighting cancer（癌症）.In 2005，he had cancer and was told that he had only six months to live.However，he continued taking care of his trees rather than lying on the hospital bed."Working is the best medicine.Planting trees helps to fight cancer，" he often jokes.
Now，at the age of 85，Wang Chengbang is still working.
（1）Is it an easy job for Wang Chengbang to plant trees？
（2）How many trees has Wang Chengbang planted so far？
（3）What is Wang Chengbang successful in？
（4）In the summer holiday，do you want to be a volunteer to work with Wang Chengbang？Why or why not？
Governments around the world are pushing for an end to plastic straws （吸管） and bags.More and more businesses are turning to paper products as a choice.Paper is considered by many to be better than plastic.However，it，too，is harmful to the environment.
Firstly，paper bags and straws are made from trees.Trees，as you know，can reduce （减少） carbon dioxide （二氧化碳） levels in the atmosphere. Theycan slow down climate （气候） change.An increase in the use of paper bags can cause more acts of cutting down trees.
Secondly，products made from paper require more energy and water.About 10 percent more energy and four times as much water is used to produce a paper bag than a plastic one.You might say that we can use recycled paper to save that energy and water.This seems to be a good idea.However，it takes even more energy and water to go through the recycling process than to make a brand new paper bag.Products made from recycled paper are also often short﹣lived.
Thirdly，paper products are heavier than plastic ones.That means they require more oil to transport.Seven trucks are needed to transport two million paper bags，while only one truck is needed to transport the same number of plastic bags.The increased weight also leads to a large amount of waste once the bags are thrown away.
Paper products are actually a lose﹣lose for both the environment and businesses.They are more expensive than plastic products.A paper straw costs about 5 to 12 cents，while a plastic one usually costs only about 2 cents.
The most environment﹣friendly solution is to avoid single﹣use products altogether.Products like glass water bottles and steel straws can be used over and over again.They are much better than either paper products or plastic products.Through increasing the use of these products，you can greatly reduce your throwaway waste and truly make our Earth a greener place!

Prepare for Water Day Zero
Last year，Cape Town said it was facing Water Day Zero．That was the date when the city's taps would go dry．It was first expected to arrive in April，2018． Thanks to hard efforts and a rainy season，it has been put off（推迟）．（1） ．And it may hit cities all over the world．
How did Cape Town get into a Water Day Zero situation？The city gets its water from six reservoirs（水库）．They usually fill up during the rainy season，from May through August．However，since 2015，the city had been suffering from its worst drought（旱灾）in a century．（2） ．Even worse，Cape Town's population grew greatly．As a result，the need for water rose．
（3） Because of climate change，serious droughts are becoming more and more common．At the same time，people are moving to cities．The United Nations says by 2050，two thirds of the world's population will live in cities．Since 2014，southeastern Brazil has been suffering from its worst water shortage in 80 years．In Mexico City，many of the 21 million people only have running water for half of the day．
Luckily，steps can be taken to avoid water crises（危机）．To start with，all of us can do something to save water and slow down climate change．（4） At the same time，water pollution must be stopped．
The world now has a chance to stop a series of Water Day Zero crises． If we don't act，many cities may soon face a time when there isn't a drop to drink．
| A．Cape Town is not alone． B．The serious situation seems to be improved． C．Water levels in the reservoirs became very low． D．Cities can build more water﹣recycling factories． E．However，the problem is very likely to appear again． F．More and more countries are paying attention to the problem． |
