介绍:
1.学校是学生学知识的殿堂。
[误] School is a palace where students learn knowledge.
[正] School is a palace where students acquire/attain knowledge.
learn 后一般只接具体的学习内容，如 learn English（学英语），learn to play basketball（学打篮球）等。但宽泛的“学知识”不能用 learn，而应用acquire/obtainknowledge，因为那才是地道的表达。
2.让我们详细讨论一下这个问题吧。
[误] Let&`&s discuss this matter in details.
[正] Let&`&s discuss this matter in detail.
in detail 一起相当于一个副词，指“详细地”；而 in details 中，details 是名词，指“细节”。所以，上面的句子也可以表达为 Let&`&s discuss the details of this matter 或 Let&`&s go enter into details。
3.在会上他做了一个总结，主要意思如下
[误] He made a final report at the meeting. The main idea is asfollow...
[正] He made a final report at the meeting. The main idea is asfollows...
as follows 是个习语，不管后面要讲的内容有几项，follow 后面一律加s。
4. 你认为这本小说怎么样
[误] How do you think of the novel?
[正] What do you think of the novel? /How do you like the novel?
中国人不习惯说what doyou think 中国人的思想认为如何就是英文how
what do you think of 相当于what&`&s your opinion of, 而英语中无 how do you think of sth.的说法。
5. 蔬菜变黄了
[误] If you had put these vegetables in the refrigerator earlier, theywouldn&`&t have turned yellow.
[正] If you had put these vegetables in the refrigerator earlier, theywouldn&`&t have rusted.
英语中用 rust（生锈）来描述蔬菜因失去水分和营养而变黄的状态。
6. 会上有许多观众
[误] There was a large number of audience at the meeting.
[正] There was a large audience at the meeting.
audience 是集合名词，为“观众”的总称。所以“观众多”应说 a large audience，“观众少”则应说 a small audience。又如：An audience of millions watched the royal wedding on TV(百万观众在电视上观看皇家婚礼）。
7. 独生子女
[误] she is a single child.
[正] she is an only child.
only child 是一个固定搭配，而且 only 强调“唯一，只有一个”，而single 常用于指“单身的”。例如：Maryis single（玛丽还没有成家）。
apple pieorder 井然有序
apple ofdiscord 争端；祸根
One rottenapple spoils the barrel. 一只烂苹果烂一筐苹果
apple-polish奉承
apples andoranges 风马牛不相及的事物
apple ofsodom 金玉其外，败絮其中
dead sea apple不可靠的成就；令人失望的事情
