这组题混合了用语法把意思说清楚的五项技能：时态、冠词、主谓一致、连接词和情态动词。题目由易到难。先写下自己的答案，再打开解析。
把做错的错误类型列成简短清单。错题记录与重测队列是方便的存放处，写作修订对比视图让你把改正后的段落和初稿做对比。
题目
1. 选出正确形式：By the time I reached the cinema, the film (started / had started).
查看答案
had started。 两件过去的事：电影先开始，我后到。较早的事用过去完成时。写成：By the time I reached the cinema, the film had started.
2. 用 a、an、the 或不填来填空：She bought ___ umbrella because ___ sky was grey.
查看答案
an … the。 Umbrella 以元音音开头，而且是新信息，所以用 an。Sky 是说话人和读者都知道的唯一事物，所以用 the。完整句子：She bought an umbrella because the sky was grey.
3. 选择：The price of the tickets (is / are) rising.
查看答案
is。 划掉 of the tickets。主语是 price，是单数。
4. 合并两个句子，表示转折：He studied for weeks. He did not pass the test.
查看答案
Although he studied for weeks, he did not pass the test. 另一个正确的写法：He studied for weeks, but he did not pass the test. 同一句里不要同时用 although 和 but。
5. 选出最合适的情态动词：Dark clouds are gathering, so it ___ rain soon. (must / may / will)
查看答案
may。 乌云是可能性的证据，不是确定性的证据。Will 好像知道未来，must 则用于对已经成立的事情做结论。
6. 改错：If she will call, I will answer.
查看答案
If she calls, I will answer. if 之后用现在时表示将来的意思。will 属于主句。
7. 改错：Despite the weather was cold, we swam.
查看答案
Despite the cold weather, we swam. 或 Although the weather was cold, we swam. despite 需要接名词或 -ing 形式。想接完整从句就用 although。
8. 改正一致性：Neither the teacher nor the students was late.
查看答案
Neither the teacher nor the students were late. 用 neither … nor 时，动词和最近的名词一致，这里是 students，复数。
9. 改正所有错误：Yesterday I have seen an accident near school. Driver of the car were shocked.
查看答案
Yesterday I saw an accident near the school. The driver of the car was shocked. 共四处改动：(1) saw，因为 yesterday 是已结束的时间；(2) the school，是已知的地点；(3) The driver，单数可数名词需要限定词；(4) was，因为主语是 driver，不是 car。
10. 用正确的时态和连接词重写这段话：The lights are off, so they will be asleep. They went to bed early because they were tired, so they woke up at dawn.
查看答案
The lights are off, so they must be asleep. They went to bed early because they were tired, and they may wake up at dawn. 改动：must be 用于根据证据得出的结论；原文同时用 because 和 so，把因果弄混了，所以第二个连接改成 and；最后一个从句是预测，所以 may wake up 合适。只要意思清楚，也有其他自然的写法。
如果你做错了
把每种错误类型对应到相关课程，再自己写几个新句子重复练习。

| 第 1、6 题和第 9 题一部分（时间先后、已结束的时间词、if 从句） | 选择时态来表达时间关系 |
| 第 2 题和第 9 题一部分（a、an、the、无冠词） | 在可数名词前使用冠词 |
| 第 3、8 题和第 9 题一部分（找出主语） | 纠正主谓一致 |
| 第 4、7 题和第 10 题一部分（转折、原因、结果） | 用连接词表达想要的转折或因果 |
| 第 5、10 题（确定与可能） | 用情态动词区分确定与可能 |
改正错误后，用同样的规则重写你自己作业里的一小段。这样能检查你是真的会用这个想法，而不只是会挑错。
反复出现的错误类型，自己很难看出来，因为你读到的是自己想写的内容。老师在英语（第二语言）线上一对一补习中阅读你自己的句子，就能指出其中的规律。
