Dear Sir or Madam,

My name is Li Hua. I am a student from a high school in China. I had recently bought a book from your website. However,some problems have arisen,that makes me upset. I am writing to complaint about them.

First of all,the book I ordered reached to me ten days late than expected,which brought me lots of inconvenience. What's more,when I looked through them,I found that a few pages are missed,which makes me very disappointing. I know that you are a famous book?selling website,but my experience shows how your service needs improvement. I hope you can sent me another book as soon as possibly.

                                                                       Li Hua

This is Sally Smith reporting World News from Los Angeles,California. California is still battling 1        huge fires that are sweeping across the states. Thousands of people have 2       (lose) their homes although 3       (thank) ，no one has been killed. Firefighters are trying new ways to help save people's homes. This includes using helicopters to bring water 4        the sea. It is thought that some teenagers 5        have started the fires. About three hours ago,the police arrested the two 6       ( suspect) . I can see from here that damage to the environment is very bad. The fires have already damaged two hundred and sixty square kilometers of forests. These are mainly old redwood trees 7        are very important to the ecological environment of the area. Some of the trees are hundreds of years old and will be damaged or lost 8       ( complete) if the fires are not brought under control quickly. High winds in the area are helping the fires 9       (spread) . I will bring you another update in an hour.

This is Sally Smith,reporting to you 10       (live) from Los Angeles,California.

Do you feel like you have too much homework every day? As you know,homework is a major part of going to school. Luckily,there are several things you can do to make homework less work.

* 1 Most high school students have between two and three hours of homework a night. If it is a heavy homework day,you may need to devote even more time. It is a good idea to come up with some kind of homework plan,especially if you are going to play sports or do other activities after school.

* 2A bedroom,study or any room where you can get away from noise is the best place to get homework done. But don't study on your comfortable bed where you might fall asleep fast.

* 3 When you start your homework,do the hardest work first. Some people like to start with the easiest thing to get it out of the way. But you'll have the most energy and focus when you begin. It is best for you to use this mental power on the subjects that are the most challenging.

* 4 Most people's attention span (注意力的持續(xù)時(shí)間) does not last very long,so take some breaks while doing your homework. Sitting for too long without relaxing will make you less productive. Taking a 15-minute break every hour is a good idea for most people.

* 5 Sometimes even though you are paying attention in class,certain subjects seem too hard. The first place to turn for help is your teacher. Sometimes your parents can help you. You may also be able to get some help from another student or a personal tutor.

   A. Get to work.

   B. Get help when you need it.

   C. Watch where you work.

   D. Do the homework by yourself.

   E. Make a homework plan.

   F. Go to do other activities after school.

   G. Take a break.

As we all know,health is very important. Only when we are healthy can we study good and enjoy life. Therefore,many teenagers don't pay any attentions to their health,especially during the holidays. They spend too much times watching TV,playing computer games and chat on the Internet all night,that is bad for their health. Firstly,this may make them to near?sighted. Besides,their bodies become more weaker. Thirdly,they will lose the chance to communicate with others face to face as they never go out,which may have a bad effect to their mental health.

In my opinion,they should spend less time in the front of the TV or the computer,go out to take some exercise,play some sports,visit some friends and have a healthy lifestyle.

A young man hurried into his town library. He went 1        one of the old librarians and said to her 2       (eager) ，"Good morning. Do you remember that you persuaded me to borrow 3        book about Greek history a week ago? "the young man asked. The librarian felt very proud because she was always 4       (try) to persuade young people to take out books on Greek history,5       she rarely found one 6        was willing to accept her suggestions. "Yes ," she answered, "Do you want to take it out again? Do you think 7        is very interesting?" "No,of course 8       ”，said the young man. "But when I was taking it home,I met a girl on the bus,and I wrote her telephone 9        in the book. I want to telephone her,so please,may I look at that book again?" The librarian's10       (express) changed at once,and she left the young man without a word. Later,she brought the book to the young man.

The concept of obtaining fresh water from icebergs that are moved to populated areas and barren regions of the world was once treated as a joke more appropriate to cartoons than real life. 1,especially since scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food.

Glaciers (冰河) are a possible source of fresh water that has been overlooked until recently. Three quarters of the Earth's fresh water supply is still tied up in glacial ice,2 that it could maintain all the rivers of the world for 1 ,000 years. Floating on the oceans every year are 7 ,659 trillion metric tons of ice stored in 10 ,000 icebergs that break away from the polar ice caps,more than ninety percent of them from Antarctica.

Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice,3 ，rather,they are formed entirely on land,breaking off when glaciers spread over the sea. As they drift away from the polar region,icebergs sometimes move mysteriously in a direction opposite to the wind,4 Because they melt more slowly than smaller pieces of ice,icebergs have been known to drift as far north as 35degrees south of the equator in the Atlantic Ocean. To move them to parts of the world where they are needed would not be too difficult.

5,such as the prevention of rapid melting in warmer climates and the storing of fresh water in great volume. But even if the icebergs lost half of their volume in moving,the water they could provide would be far cheaper than that produced by removing salt from sea water.

   A. which is formed when the sea itself freezes

   B. Difficulties arise in other technical matters

   C. But now it is being considered quite seriously by many nations

   D. Icebergs are not too much influenced by the temperature.

   E. pulled by subsurface currents

   F. a reservoir (蓄水池) of untapped fresh water so large

   G. People often get fresh water by removing the salt from sea water.
