1.I love the weekend, because I get up early on Saturdays and Sundays.
答案 needn't 句意:我爱周末,因为我不必在周六和周日早起。needn't表示不必。
2.Why didn't you tell me about your trouble last week? If you (tell)me, I could have helped.
答案 had told 句意:你上周为什么不告诉我你遇到的麻烦?如果你告诉我,我本可以帮你的。本题考查虚拟语气。根据题干中的could have helped和last week可知设空处为与过去事实相反的虚拟语气,故答案为had told。
3.—Can't you stay a little longer?
—I really go now;my daughter is home alone.
答案 must 句意:——难道你不能再多待一会儿吗?——现在我真的必须得走了,我的女儿独自一人在家。本题考查情态动词。根据上下文可知,答案为must(必须)。
4.I wish I (be) at my sister's wedding last Tuesday,but I was on a business trip in New York then.
答案 had been 句意:我希望上周二我参加了我姐姐的婚礼,可是那时我正在纽约出差。考查虚拟语气。wish后的从句对过去情况进行虚拟时谓语动词应用had done。
