2. 不定式考点

同类型动词：make, let, see, hear, watch, notice, feel, find, observe等

do nothing but/except, do anything but/except
e.g.: We had nothing to do except watch TV at home during the raining days.
3. 现在完成时：have/has done
与现在完成时搭配的时间状语：
1)  already，yet，ever，never，recently，lately，as yet
e.g.: We haven’t reached an agreement as yet.
2)  up to now, so far, all day long, all one’s life

  by the time/before + 过去时间；when/before + 一般过去时从句：e.g.: We had done a lot of preparation before the guests came.
2)  在 no sooner….than, hardly… when…的结构中。前面的（主句）的动词用过去完成时。
e.g.: No sooner had I sat down than he stepped in.
3)  宾语从句中，表示从句的动作或状态先于主句的过去式谓语动词的动作之前发生。
e.g.: He got to the railway station and suddenly realized that he had forgotten to bring his ticket.
5. 将来完成时 will have done

By the time + 将来时间, 主句用将来完成时态。
e.g.: By the time next year, the factory will have produced 20 million cars.
到明年这个时候，这家工厂将会生产了2千万台轿车。
6. 同位语从句：用that引导
由同位语从句修饰名词常见的有：fact, thought, idea, news, belief, doubt 等
✧ 7. 虚拟语气
1) 与现在事实相反：if + were/一般过去动词，情态动词(would/should/might could)+ 动词原形
  与将来事实相反：if + were to + 动词原形，情态动词(would/should/might could)+ 动词原形
  与过去事实相反：if + had done， 情态动词(would/should/might could) + have done
2） 表示建议，要求，请求，命令，坚持等意义的词语所接的宾语从句:
用虚拟语气should + do
如suggest, propose, recommend, advise, order, demand, require, request, ask, insist, urge 等
3）It is + adj. + that 从句：（should）+ do
  典型的形容词有important，vital，essential，natural，strange，incredible，necessary等
4）Lest（以防），for fear that（唯恐），in case（以防）引导的从句：should + do
5. as if（好像），wish（希望），would rather（宁可），if only（只要），等词语引导的从句：过去时态
5）It is …time + 从句的结构中：从句动词用一般过去时。
  It was … time + 从句的结构中：从句中动词过去完成时（had done）。
6）介词短语可相当于一个条件句时要用虚拟语气，如：without，but，but for（要不是…）
e.g.: But for the heavy rain, we would have been there in time.
7. would rather + that 从句：从句中的动词用一般过去时态。
e.g.: I would rather you came here tomorrow。
注意：以上虚拟语气中，加黑部分的内容是最常见考点。
✧ 8. 主谓一致-------就近原则
1）There be 句型中，be 动词的形式与最临近的名词保持一致。
e.g.：There is a pen, a knife and several books on the desk.
2) either…or,  neither…nor,  not only… but also,  not … but…连接两个主语时，谓语动词与最临近的一个保持一致。
e.g.：Either you or he is to go.
  主谓一致--------就远原则
3) 主语后面跟有with, together with, except, along with, as well as 等词或词组连接其他名词时，谓语动词只与其相距远的名词保持一致。
e.g.: The teacher，as well as some students, is visiting the factory.
✧ 9. 分词作状语
1）. Doing(与后面的名词构成主动关系)……,  名词（主语）+ 谓语 + 宾语（或状语）
Looking at the beautiful picture, the boy felt excited.
2）. Done (与后面的名词构成被动关系) ……,  名词（主语）+ 谓语 + 宾语（或状语）
Seen from the top of the hill, the village is very small.
✧ 10. 分词作表语
主语（人）+ be / 系动词+（过去分词形式）done
主语（物）+ be / 系动词+（现在分词形式）doing
11. 倒装句型
1）在省略if 的虚拟语气条件句中，were，had 或should常置于句首，构成倒装。
e.g.: If you had been more careful, such mistakes might have been avoided.
如果你之前仔细一点，这样的错误也许是可以避免的。
= Had you been more careful, such mistakes might have been avoided.
2) so, nor, neither, 开头的句子中 e.g.: She does like coffee; Nor do I.  她不喜欢咖啡，我也是。
3) 由具有否定意义的副词，连词及词组（rarely, never, no sooner, little, hardly, seldom, at no time, in no way等）开头的句子.
e.g.: Never have I seen such a wonderful movie.  我从未看过如此精彩的影片。
