比如:1:A:(your friends,write)_____a lot of e-mails? B:no,___.they(do)____an exercise. 2:(the weather,affect)_____your mood? 3:A:(jane study)____at the library this evening? 4:(jane play)______pool every evening?
1. Do your friends... (your friends是第三人称复数,一般现在时态,所以用do) 2. No, they don't. They do an exercise(因为主语是they,复数,且为一般现在时态,所以用do)--(当然此句也可以用过去时态) 3. Does the weather affect you mood? (the weather第三人称单数,用does) 4. Does Jane study...(Jane是第三人称单数,可以用did或Is Jane doing) 5. Does Jane play pool every evening?(此句说的是Jane平时的活动,所以用一般现在时态,Jane第三人称单数)
用BE提问的句子,是问主语"是不是"...吗? Are you a worker?你是工人吗? Is he listening to music?他是在听音乐吗? 用DO提问的句子,是问主语"做不做"... Do they get up at six in the morning?他们是早上六点起来吗? Does he play football after school?他放学后踢足球吗?
