强调句型如下： It was I that/who saw her in the park yesterday. 昨天在公园里看见她的是我。(强调主语) It was her that I saw in the park yesterday. 我昨天在公园里看到的是她。(强调宾语) It was in the park that I saw her yesterday. 我昨天看到她是在公园里。(强调地点状语) It was yesterday that I saw her in the park. 我在公园里看到她是在昨天。(强调时间状语) It wasnt until he came back that I went to bed. 直到他回来我才睡觉。(一定要注意被强调句型中的谓语动词否定的转移)。 【提示】　①不管强调什么状语，不被强调部分都用that引导。 ②not until的强调句型是考查的重点。 ③区分定语从句和强调句型的方法：强调句型中如去掉It is/was和that后，句子还原仍成立；而定语从句去掉It is/was和引导词后句子中缺少成分，不成立。 【对接高考】 (2013·新课标全国卷Ⅱ)It was only after he had read the papers Mr. Gross realized the task before him was extremely difficult to complete. A．when　　　　　 B．that C．which D．what 【解析】　句意：直到他读了文件之后，格罗斯先生才意识到他面临的任务很难完成。本句为强调句型，强调了时间状语only after he had read the papers。根据强调句结构“It is/was＋被强调部分＋that＋剩余部分．”可知选B项。此外，我们也可以将It is/was与空格去掉来验证此句是不是一个强调句。 【答案】　B (2)afford v．买得起；承担得起；经得起；提供 We cant afford to pay such a price. 我们付不起这个价钱。 Dancing affords us pleasure. 跳舞给我们带来快乐。 afford sth.负担得起……的费用 afford to do sth.负担得起做……的费用 They did not consider whether they could afford the time or not.他们没有考虑是否抽得出时间。 【提示】　afford常与can，could，be able to连用。 2．Ford found a way to massproduce the motor car cheaply，making it possible for many more people to own one.(教材P46)福特找到了一种廉价的成批制造汽车的办法，这使更多的人拥有汽车成为可能。 句中making it possible for many more people to own one 为现在分词短语作结果状语，可以改为定语从句：which made it possible for many more people to own one。 Another disaster hit a mine in Shanxi，causing many deaths.山西又一次发生了矿难，造成了许多人死亡。 The boss was arrested，leaving the workers unemployed. 老板被逮捕了，工人们也失业了。 分词或分词短语作状语时，可以表时间、原因、结果、条件、让步、行为方式、伴随状况等。常见以下形式： ①v.＋-ing与句中的主语构成逻辑上的主谓关系，与句中的谓语动词同时发生或基本上同时发生。 ②having＋v.＋-ed与句中的主语构成逻辑上的主谓关系，先于谓语动词发生。 ③v.＋-ed与句中的主语构成逻辑上的动宾关系。 ④being＋v.＋-ed与句中的主语构成逻辑上的动宾关系，且与谓语动词同时发生，一般作原因状语置于句首。 ⑤having been＋v.＋-ed与句子的主语构成逻辑上的动宾关系，且先于谓语动词发生。 Hearing their teachers voice，the pupils stopped talking at once.一听到教师的声音，学生们立即停止讲话。 Not knowing how to work out the difficult physics problem，he asked the teacher for help. 因为不
