Which of the following is NOT true according to the passage?____
Which of the following is a common characteristic of young smokers?____
In this passage the author puts an emphasis on ____.
In has been shown that children who smoke have certain characteristics. Compared with non-smokers they are more rebellious, their work deteriorates as they move up school, they are more likely to leave school early, and are more often delinquent and sexually precocious. Many of these features can be summarized as anticipation of adulthood. There are a number of factors which determine the onset of smoking, and these are largely psychological and social. They include availability of cigarettes, curiosity, rebelliousness, appearing tough, anticipation of adulthood, social confidence, the example of parents and teachers, and smoking by friends and older brothers and sisters. It should be much easier to prevent children from starting to smoke than to persuade adults to give up the habit once established, but in fact this has proved very difficult. The example set by people in authority, especially parents, health care workers, and teachers, is of prime importance. School rules should forbid smoking by children on the premises. This rule has been introduced at Summerhill School where I spent my schooldays. There is, however, a risk of children smoking just to rebel against the rules, and even in those schools which have tried to enforce no smoking by corporal punishment there is as much smoking as in other schools. Nevertheless, banning smoking is probably on balance beneficial. Teachers too should not smoke on school premises, at least not in front of children.

The difference between us and Africans, as far as music is concerned, is that ____.
It has been thought and said that Africans are born with musical talent. Because music is so important in the lives of many Africans and because so much music is performed in Africa, we are inclined to think that all Africans are musicians. The impression is strengthened when we look at ourselves and find that we have become largely a society of musical spectators (旁观). Music is important to us, but most of us can be considered consumers rather than producers of music. We have records, televisions, concerts, and radios to fulfil many of our musical needs. In most situations where music is performed in our culture it is not difficult to distinguish the audience from the performers, but such is often not the case in Africa. Alban Ayipaga, a Kasena semiprofessional musician from northern Ghana, says that when his flute (长笛) and drum ensemble (歌舞团) is performing, "Anybody can take part". This is true, but Kasena musicians recognize that not all people are equally capable of taking part in the music. Some can sing along with the drummers, but relatively few can drum and even fewer can play the flute along with the ensemble. It is fairly common in Africa for there to be an ensemble of expert musicians surrounded by others who join in by clapping, singing, or somehow adding to the totality of musical sound. Performances often take place in an open area (that is, not on a stage) and so the lines between the performing nucleus and the additional performers, active spectators, and passive spectators may be difficult to draw from our point of view.
