1.看到"together with”就选单数!
Professor Wang, together with his colleagues,____working on the project day and night.
A. are B.is C.will D. to
答案: B。
正式解释:谨记together with的主语是其前面的人，且几乎都考单数。类似常考词还有with, along with和as well as。
2.看到“非谓语 的主语”(常在句中逗号后)，主动就选 to do或ing，被动就选过去分词!
____from the outer space, the earth looks like a blue ball.
A. See B. Seeing C.Tosee D. Seen
答案: D。
正式解释：此类题只需看逻辑主语(为方便可直接理解为题目主语)和动词的关系即可。题中逻辑主语the earth,与see是被动关系，所以用过去分词seen表被动;主动关系时，若表状态或进行用ing,若表目的或将来用to do;若有完成时就翻译成:已经......，看是否合句意。
3.看到“否定词或only放句首"就选倒装!
Only in this way____the plan successfully.
A. we can carry out
B. we can agree on
C. can we agree on
D. can we carry out
答案: D。
正式解释:否定词或only位于句首常引起倒装。倒装即把句子变为疑问语序，也就是先助动词再到主语。选项正常语序本是we can carry out,倒装后为can we carry out。
4.看到"it is/wa..."或"is/was t...就选that或who!
It was in 1949____the People's Republic of China was founded.
A. when
B. while
C. as
D. that
答案: D。
正式解释:看到it is或it was开头立刻怀疑是否考强调。只要把it is/was...that/who...去掉，若剩下的仍然能成为一个正常句子即是考强调。一旦确定考强调，谨记强调的是人类就选who, 强调的是非人类就选that,别无他选。不管强调的是时间、地点还是理由，只要是非人类都选that。
5.看到“by"就选完成时!
By the time Igot home, my mother____to bed.
A. went B. was getting C. had gone D. has gone
答案: C。
正式解释:看到by+时间，就考完成时。by+ 现在时间，选现在完成 have done; by+过去时间，选过去完成had done; by+将来时间, 选将来完成will have done。此外，看到so+far就选现在完成时。
