【題目】With more forests being destroyed, huge quantities of good earth ______ each year.

A. is washing away B. are being washed away

C. are washing away D. is being washed away

【答案】B

【解析】句意:隨著更多的森林被毀，大量的沃土每年正在被沖走。此題考查動詞的時態(tài)和語態(tài)及主謂一致。當(dāng)quantities 作主語時，謂語動詞用復(fù)數(shù)形式。根據(jù)句意可知，大量的沃土正在被沖走,所以用現(xiàn)在進(jìn)行時的被動語態(tài)。

【題目】Maybe you are an average student. You probably think you will never be a top student. This is not necessary so, however. Anyone can become a better student if he or she wants to. Here is how.

1) Plan your time carefully. When you plan your week, you should make a list of things that you can have to do. After making the list, you should make a schedule of your time. First time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying. Don't forget to set aside enough time for entertainment. A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.

2) Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room. Free from everything but study materials. No games, radios, or television. When you sit down to study, concentrate on the subject.

3) Make good use of your time in class. Take advantage of class time to listen to everything the teachers say. Really listening in class means less work later. Taking notes will help you remember what your teachers say.

4) Study regularly. When you get home from school, go over your notes. Review the important points that your teachers mentioned in class. If you want to know what your teacher is going to discuss the next day, read the material in advance. This will help you understand the next class. If you do these things regularly, the material will become more meaningful, and you will remember it longer.

5) Develop a good attitude about tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won't end if you don't pass a test, so don't be overly worried.

There are other methods that might help you with your studying. You will probably discover many others after you have tried these.

【題目】

Long bus rides are like television shows. They have a beginning, a middle, and an end—with commercials thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window. "Buy Super Clean Toothpaste. " "Drink Good'n Wet Root Beer. " "Fill up with Pacific Gas. " Only if you sleep, which is equal to turning the television set off, are you spared the unending cry of “ You Need It! Buy It Now!"?

The beginning of the ride is comfortable and somewhat exciting, even if you've traveled that way before. Usually some things have changed—new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it's fun to try to figure it out the first hour or so. If the driver is particularly reckless or daring, the ride can be as thrilling as a suspense story. Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you've got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.

The end of the ride is somewhat like the beginning. You know it will soon be over and there's a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. By now you've sat with your legs crossed, with your hands in your lap, with your hands on the arm rests—even with your hands crossed behind your head. The end comes just at no more ways to sit.

A. they are both long and boring, with commercials disturbing you all the time

C. they are both exciting, with new things to see in every three or four minutes

D. they both make you sit in your seat uncomfortably for a very long time

【2】The writer sounds as if he likes __________.

A. reckless bus drivers B. sleeping on bus trips

C. salty food D. commercials

A. tiring B. comfortable C. exciting D. boring

【4】When passengers get tired, they tend to __________.

A. watch the commercials B. eat food

C. cross their legs D. change their ways to sit

A. To warn people of the danger on long bus trips.
