【一般將來時(shí)】

1.(2009陜西) Dr. Smith, together with his wife and daughters, __________ visit Beijing this summer.
A. is going to B. are going to C. was going to D. were going to
答案：A
解析：句意“Dr. Smith將在今年夏天和妻子女兒們一起游覽北京”。本題考查主謂一致。由this summer可知本句應(yīng)用一般將來時(shí)，故排除C、D；together with連接并列主語時(shí)謂語動(dòng)詞單復(fù)數(shù)應(yīng)取決于其前面的主語，故選A。

2.(2008全國II) If their marketing plans succeed, they __________ their sales by 20 percent.
A. will increase B. have been increasing?C. have increased D. would be increasing
答案：A
解析：在if條件從句中，用一般現(xiàn)在時(shí)來指代一般將來時(shí)，可以得知他們的市場(chǎng)運(yùn)作計(jì)劃還沒有成功，所以增加銷售額也是個(gè)將來的動(dòng)作，應(yīng)該用will increase。

【過去將來時(shí)】

1.(2009湖南) When he _______ the door, he couldn’t find his keys.
A. would open B. opened C. had opened D. was to open
答案：D
解析：句意“當(dāng)他要開門的時(shí)候，發(fā)現(xiàn)鑰匙不見了”。was to do在此表示wanted to do或intended to do，would do在這里有情感意義，所以被排除。
