Trees are useful to man in three very important ways. The first important way is that they provide man with food, wood and other products. Trees provide not only man with food, but also many animals with food. Without trees many animals could not live on the earth. It's not easy for man to live on the earth, either.
The second important way is that trees give us shade. On a hot summer day, people are eager(渴望)to have a rest under the shade of a tree after they have walked a long way. You can imagine how important the shade of a tree is to man and to animals.
The third important way is that trees help to prevent drought and foods. However, in many parts of the world, man has not realized the third important way. He has cut trees down in large numbers. In the end he finds that he has lost the best friends he had.

Dear Wang Fang,

    Thank you for your letter. You wrote to ask me about American social customs(风俗) in their dinner party. You are asking the right person. I once lived in America for five years. Now I'll tell you something about it.

    It's a good idea to bring a small present when you go to a dinner party. Flowers are always nice, or you may bring a bottle of wine if you know that your friends drink it.

    You should arrive(到达) on time or five minutes late. Don't get there early. If you're going to be more than fifteen minutes late, you should call before.

    Try to be free at the dinner table. If you don't know about choosing(选择) the right fork or knife, just watch the other people, and follow them. If you still have no idea of what to do, ask the person beside you .

    If you like the food, say so. Of course, you'll thank them for the meal and for their kindness. It's also a good idea to send a card to thank them the day after.

    In 1945，6 planes and 17 men disappeared without a sign, all in one day. This was Flight 19. Flight 19's captain was Lieutenant Charles Taylor. Flight 19 was a usual flight. It took off at about 2:10 p.m. from Miami. The weather was very normal on that December 5th of 1945. A message was received at 4：00 p．m.that told about pilot Taylor not knowing the way to go because his compass(指南针) was running around and around.

    After that，it was never heard from again.While searching for it，a search plane was also lost.The search for the both continued until December 10th of that same year.None of the things from Flight 19's planes，or from the search plane，was ever found.It is one of the most infamous disappearances. Searching for Flight 19 lasted five days，and covered 380，000 square miles. Dr. Kripke suggests that the accident happened because of a vortex(涡流).

    Listening to someone speaking in a second language over the telephone can be very challenging because you cannot see the person you are trying to hear. You may not realize that your pronunciation isn't clear. So pay special attention to your pronunciation and speak as slowly as possible.

    {#blank#}2{#/blank#}

    Don't pretend to understand everything you hear over the telephone. Don't be afraid to remind the person to slow down more than once.

    {#blank#}3{#/blank#}

    Ask another student to practice talking on the phone with you. Try to talk for at least fifteen minutes. The most important thing about practicing telephone English is that you are not able to see others' mouths.

    {#blank#}4{#/blank#}

    There are many ways to get free telephone English practice. After business hours, you can call and listen to recorded messages. Write down what you hear the first time, and then call back and check if your notes are right.
