A.4 

B.5 

C.6 

D.7

答案

参考答案:C

解析:解析 要使比赛的天数最少,则需要每天比赛的选手尽可能的多,加之每名选手每天最多参加一场比赛。第一天总共比赛48÷2=24场,还剩24名;第二天总共比赛24÷2=12场,还剩12名;第三天总共比赛12÷2=6场,还剩6名;第4天总共比赛6÷2=3场,还剩3名。第五天选2人进行比赛,淘汰1人,剩下2人,第六天决出冠军。 因此,比赛至少需要举行6天。 考点:其他

Near the village, there is an old famous temple. Some people want to build new houses where the temple now stands, because they can find no other area to build them, while others disagree with them. They meet to decide how to solve the problem. Here are their opinions about it.

The expert wants to protect the temple and believes that there are some interesting things buried in the ground. If it is destroyed or moved, people may never learn about how people lived in the past.

The businessman thinks that the houses should be built. History is important, but we must think about the future. The village needs development and building new houses will offer jobs to hundreds of people.

Villager A says, “We should build the new houses because we need houses to live in.”

Villager B says, “We should protect the temple because it can attract many tourists to come for a visit. If the temple is destroyed or moved, we will lose a lot of business.”

The village leader thinks that he has a duty to make life better for the villagers. They need jobs and new houses. He also thinks the cultural site (遗迹) is important and they should be careful with it as well.
