In the search for clean． renewable（可再生的） energy． wind power might be the perfect choice．People have been using the power of the wind for centuries．Since ancient times， wind power has been used to move ships， grind （碾谷）and so on，Around the end of the 19 thcentury， the invention of the wind turbine（涡轮机） made it possible to use Wind to produce electricity．
The first advantage of wind power is that it is a renewable resource{能源）． No mater how much wind we use to produce electricity， it will never run out． Secondly， wind power i a clean resource of enery， meaning it produces electricity without harmful emissions（排 放物）． Thirdly，although wind turbines can be very tall， each uses only a small piece of land． This means that the Land below can still be used．
Yet． wind energy has some disadvantages．One of the disadvantages is that the large spinning lodes（螺旋桨叶） of the wind turbines can be dangerous to birds． The second is that the turbines create noise pollution． The sound may make the people nearby uncomfortable． The third，wind can not provide a constantsupply（供应） of energy． Even the windiest places on Earth are peaceful． Without a strong wind， wind turbines are not able to produce electricity． That means wind power isn't suitable as the only resource of electricity．
Although wind energy has certain disadvantages， there is no reason why we should give up this renewable and clean resource of energy． Wind energy certainly is one of the bight hopes of our future．

Are you carrying too much on your back at school? I'm sure lots of children of your age will, say "Yes". Not only the students in China have this problem, but children in the United States also have heavy school bags.
Doctors are starting to worry that younger and younger students are having back and neck problems as a result of schools bags being too heavy for them.
"It's hard for me to go upstairs with my bag because it's so heavy, "said Rick Hammond, an 11-year-old student in the US.
Rick is among students who have common school bags with two straps(带子) to carry them, but many other students choose rolling(有滚轮的)bags.
But even with rolling bags, getting up stairs and buses is still a problem for children. Many of them have hurt their backs and necks because of the heavy school bags.
But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight.
Scott Bautch, a back doctor, said children under Grade 4 should stay with 10 % . But it is also important that older children don't stay with over 15 %, because their bodies are still growing. "Children are losing their balance and falling down with their school bags, "he said.
Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin workbooks for students to take home.

James wrote a play for television about a family who came to England from India, and the play was very interesting. It was bought by an American TV company（公司）.
James was then invited to go to New York to help them. He lived in Washington, which is an hour away from New York by air. The plane was going to take off at 8:30 in the morning. So he had to be at the airport at about 7:30. He ordered a taxi for 6:30 and went to sleep. He forgot to wind the clock, and it stopped after midnight. Also the driver of the taxi had to work very late that night and he got up very late the next morning.
James woke with the feeling that something was wrong. He looked at his clock. It stood there silently with the hands pointing to ten past twelve. He turned on the radio and knew it was ten. He was late for the plane.
He was just preparing his coffee when the radio sent out another news, “Reports are coming in of a plane crash（飞机坠落）near Washington airport. A Boeing 707 fly to New York crashed shortly after taking off this morning. Plane number 2234…” James suddenly turned pale（苍白）.
“My plane,” he said aloud. “If I haven’t been late, “I’d have been on the plane!”
根据短文内容,判断各句是否符合短文意思，符合的 “T”，否则 “F”。James was a writer from England.
The driver came to pick him up on time.
James was lucky because he was not able to get on the plane.
The plane crashed while flying towards London.
Sometimes bad things can change into good ones.
