2道英语题 要解析啦 详细得分

（ ） 22. He is the only one of the students who _____ a winner of scholarship for three years. 怎么不用A啊
A. is B. are
C. have been D. has been
（ ） 23. _____ of my brothers are reporters. Covering events, meetings, or sports meetings ______ their duty.
A. Each, are B. Both, is
C. Neither, are D. None, is

1.C 因为先行词是students是复数，后面 for three years，所以用have been，表延续。
2。B 根据后面Covering events, meetings, or sports meetings，报道新闻，会议或运动会知道两个人都是记者，后面因为有or连接是表并列，有或者的意思，得用单数，如果是and就用复数。

22 D 后面有 for three years 持续的时间，用完成时。 23 B Both----are --- 后面是具体责任，用单数。

D 已经拿了三年的奖学金，完成时 B 第一个空要修饰复数名词，只能用both 第二个空主语是Covering不是meetings,所以用is

22.D. is表示现在，而三年都是奖学金获得者是已经完成的动作。 23.B. are决定选both，后面的句子的主语是单数，用is。

解：设答对x道题，则答错 25—x道题，根据题意（得分不少于60分），得     4x—2（25—x）大于或等于60    解，得  x大于等于18.333333     因为x为整数，所以x大于等于19     即，至少要答对19道题

（ D ） 22. He is the only one of the students who _____ a winner of scholarship for three years. A. is B. are C. have been D. has been 理由:首先看见for three years可以确定用完成式,所以排除AB项,然后看定语从句who所连接的句子是形容he的,所以是单三.所以选D （B ） 23. _____ of my brothers are reporters. Covering events, meetings, or sports meetings ______ their duty. A. Each, are B. Both, is C. Neither, are D. None, is 理由:看见are reporters,先排除AD项.然后根据Covering events, meetings, or sports meetings 确定后面是单数名词,所以排除C项.
