They are called hybrid (混合動力的) buses. They run on diesel (柴油的) and electric power (動力). This will help keep the air cleaner. The man who took the wheel of the new bus on Wednesday noticed a difference right away. I get to have clean air for a change, said driver Melvin Day, I39。m smelling diesel all day long when I drive the old ones. The pany that builds the buses had many good things to say about them. For example, they said that they use a lot less fuel (燃料). They also said that they are 90% cleaner for the environment. The buses are very quiet, too. The buses have a diesel engine in the back and batteries (電池) on top. When the engine startsup it is powered by electricity. Then the diesel power takes over. Over time the city would Like to replace (取代) all 50 of their buses with the new hybrid buses. They hope to do this over the next three years. The city will give money to help buy the new kind of buses. One other bit of positive news: the price of bus ticket will not be increased because of the new buses.1.

The food that astronauts (宇航員) carry with them does not look like the food you eat. Some food is carried in closed bags. It is cooked and frozen (冷凍) before the astronauts get it. All the water is removed from the food. In the space capsule (太空艙), the astronaut puts the water back. He shoots hot or cold water into the food with a special gun. He eats the food through a small hole in the bag. Other foods e in bigger sizes. The astronaut puts a whole piece in his mouth at once. There can be no crumbs (碎屑). Crumbs would float (漂浮) around the capsule and get in the way. Meat, cake, and cereal often e in bitesized pieces. Astronauts cannot drink water from open cups. The water would float in drops in the air. The water is put in the special gun. The astronaut shoots the water into his mouth. Eating in space is not easy. Astronauts must learn to eat in this way.1.

There are three possible ways to improve reading. The fastest is probably a speed reading class with good books and teachers. It is quite usual for a slow reader to increase two or three times his reading efficiency (效率) during a twoday class with a positive atmosphere (氣氛), carefully picked texts and reading tests. However, this encouraging improvement often fades (消退) with time. A book about speed reading is the second method. Such a book usually gives speed and prehension （理解) tests as well as ways to improve reading. It often has all kinds of methods to make you pay attention to or be interested in the text. All the methods need a lot of time as well as hard work from the reader. Finally, a speed reading puter program is probably the most effective way to achieve top reading levels. Computers give special exercises to improve reading efficiency. Higher reading skills got with a puter screen can be changed to reading from paper. Unfortunately the inverse (轉(zhuǎn)變) way does not work so well. Speed reading software (軟件) gives enjoyable and fast reading training, thus giving the practice necessary to break longtime slow reading habits. This is the task that reading classes and speed reading books usually can39。t give to the reader.1. What is the most effective way to improve reading? A. A speed reading class. B.
