Unit 12 What did you do last weekend 重点解析Section A1.

I stayed up late to watch the soccer game. 我熬夜到很晚看足球比赛。 stay up 意为“深夜不睡；熬夜”。stay up late是指“熬夜到很晚”。如：You have to go to school tomorrow.

There we put up our tents and made a fire to keep us warm and cook food on. 在那里，我们搭起帐篷，生起火，以便保暖和做饭。put up是动词短语，意为“搭起；举起”。反义短语为put down，意为“放下；搁下”。如：Put up your hands! the teacher said. 老师说：“举起你们的手！”Please put down that knife. Its dangerous. 请放下刀，那很危险。make a fire意为“生火”。如：It is not safe to make a fire here. 在这里生火不安全。keep+sb./ sth.+adj.表示“(使)某人/物保持(某状态)”。如：We can play sports to keep us healthy. 我们可以做运动来保持健康。2. I was so scared that I couldnt move. 我害怕得都不能动了。 原句中含有so. that.这一句型，意为“如此以至于”，它可与too. to互换。如：He was so young that he couldnt go to school. = He was too young to go to school. 他年纪太小，还不能上学。move意为“搬动，移动”。move也有“搬迁”之意，常用结构为“move to.”。如：The Smiths will move to Canada. 史密斯一家将搬到加拿大。3.

Ill go before she comes back. 我会在她回来之前走。 这两个词都可以表示“以前”，但用法有所不同。ago一般仅作副词，而before可作副词、介词或连词。ago的前面一般要跟一段时间，如three days，one month等。而before能单独使用(即不连用具体时间)，泛指一般意义的“以前”。如例句1、2。表示在某一时间点或某一事件的以前时，只用before不用ago，这种用法是将before当作介词或连词使用。ago不具有这一功能。如例句3、4。 选用ago或before填空。1.

The end of the story is surprising. 故事的结尾很令人惊讶。 surprise可以作名词，意为“惊奇；惊讶”。常用于in surprise (吃惊地)、to ones surprise (使某人吃惊的是)等短语。如例句1、2。surprise还可以作动词，意为“使吃惊”。如例句3。surprised是形容词，意为“吃惊的；惊讶的”，主语一般是人，且其后多接介词at或不定式。如例句4。surprising也是形容词，意为“令人吃惊的”，主语一般是事或物。如例句5。 用surprise的正确形式填空。5.
