There is an interesting, but at the same time a sad phenomenon now: there is a rise in the number of singers and bands that have little to do with good music．Many singers or bands know little about what good music means．What is the cause of this rise?

Most of these singers have taken music as a “job” because it is a good source of making money．And if you have a good appearance and also expensive clothes to show off at your concerts or at different appearances in public, then your voice is not as important as it should be．The public will prefer to admire more the most interesting parts of your body, whether you are a girl or a boy．They will even forget about the fact that you are there to show your music skills, not your dancing, which is important too, but not at such a high level．

Therefore, we can see many young girls on TV who look very good but who have nothing to do with music．They choose to wear very provocative（挑逗性的） clothes to catch attention, but when it comes to singing they are a complete mess and one doesn’t need to have an ear for music to notice their lack of talent．But anyway, they have concerts and they enjoy travelling from one place to another．It is the public’s fault because they accept this and are pleased with this commercial music．People who enjoy this kind of music are generally young people while adults prefer listening to old good bands．

However, the young generation should understand while appearance is important, it is less important than talent and a good voice．If somebody has a great voice and wants to become a singer, he should take some special courses in this area, because they will help them improve singing abilities．

1.The passage shows that many singers consider music as _______．

A．an art serving the public　 B．a good way of making money

C．a way of living fully　　　　 D．a fashionable lifestyle

2.From the passage we can learn that _______．

A．appearance is the most important thing in the world of music

B．all people who have received training in singing can become famous

C．adults should help young people improve their abilities

D．a singer’s talent and voice are the most important factors

3.What do you think is the author’s attitude towards the rising number of new singers and bands?

A．Critical． B．Supportive． C．Tolerant． D．Worried．

4.What kind of article does this passage belong to?

A．entertainment B．sport C．comment D．Story

When nature is left alone, a balance is reached among the animals and plants living in one area. But when man starts his work in nature, the balance is likely to be destroyed. He grows a crop and takes it away to eat ;then there are no dead leaves to fall on the ground, holding water while it sinks into the surface, or decaying (腐烂) and adding humus (腐殖质) to the soil. Unless a farmer acts with knowledge and skill, he is therefore most likely to make the land poorer. To take the place of the useful matter in the crops that he removes, he uses some kind of fertilizer (肥料). Chemical fertilizers are of great help, but the waste products of animals and decaying remains of plants should also be put on the land. In some places, it is a habit to burn waste material lying about, but such burning destroys the useful matter in the dead plants. Although the ashes that are left are valuable when put on the land, a better practice is to bury the waste so that it decays and increases the humus in the soil.

In the past, when the world population was much lower than it is now, a man had little difficulty in ordinary times in growing the food that was needed. When a field had been used some years and had become tired, the farmer could move to another place. The tired land then slowly recovered. By and by grasses and other plants would appear on it and its productive power would slowly return to normal through their decay. But nature, left alone, would take a long time to bring back the land to its former state; the length of time required would depend on local conditions, but it might well be ten years.

It is a bad practice to grow the same crop in a field year after year. If the crop is changed, the land will suffer less because it is treated and used in a different way. Different plants have different effects on the soil. Therefore, a change of crop will do less harm than the growing of the same crop year after year and a regular change to grass will do good to the soil. Much will therefore be gained if different crops are grown one after another, a method known as the rotation (轮作) of crops.

1.According to the passage, the land will become poorer (   )

A. if all the dead leaves are cleared away        B. if the humus is increased after the harvest

C. if dead leaves decay in the soil by themselves  D. if waste plant material lying about is buried

2.We can learn from the passage that the tired land has slowly recovered (   )

A. when grasses and other plants appear again

B. when the treatment is given by nature alone

C. after new grasses and other plants have decayed again

D. after nature has been left alone for several months

3.A modern farmer can hardly move to another place as he did before because (   )

A. the productive power of a new field isn't higher than that of an old one

B. there are few free fields left for him to do farming

C. it takes a farmer more than ten years to start farming in a new field

D. there will be too many grasses in a new field to grow crops

4.It is most likely that the author will go on to (   ) in the paragraph following the passage above.

A. introduce other methods of planting crops     B. deal with how to prevent land getting tired

C. start another topic of how to make use of land  D. further explain what the rotation of crops is
