错例：Students receive job training can become competitive in the labour market.

这个句子中有两个动词，receive和can become，而一句话中应该只有一个谓语动词。于是改正的话就得添加一个从句结构。

Students who receive job training can become competitive in the labour market;

Students can become competitive in the labour market if they receive skills training.

也可利用ing形式：

Students receiving job training can become competitive in the labour market.

错例：There is a number of countries which know that they will soon be underwater if global warming is permitted to continue.

这里There be 结构中的主语是countries, 所以谓语动词要用are.

There are a number of countries which know that they will soon be underwater if global warming is permitted to continue.

有时在SWT中大家要会写一些比较复杂的句式，例如插入成分或同谓语成分。在写作的过程当中，每每遇到以上几种情况的时候，一定要认清主语，所有的补充内容都是针对主要展开的。

例如：Thomas Edison, one of the most distinguished scientists, is a brilliant inventor.

这里在写完第二个逗号的时候，就应该回过头来看看主语Thomas Edison是单数的第三人称，而不能被插入成分中的scientists所蒙蔽。所以这里的谓语要用is 而不是are.

错例：Cardiopathy, coupled with poor diet, lead to severe diabetes.

这就话中主语为cardiopathy, 谓语应该为单三形式。

Cardiopathy, coupled with poor diet, leads to severe diabetes.

happen, appear, disappear, rise, emerge, occur, take place 这些词都没有被动语态。

错例：The accident was similar to the one that was happened last year.

改正：The accident was similar to the one that happened last year.

错例：A part-time job offers you chance to demonstrate your ability and apply what you have learned in school.

改正：A part-time job offers you a chance to demonstrate your ability and apply what you have learned in school.

错例：A large number of people hold the believe that students' social activities should be the first priority.

改正：A large number of people hold the belief that students' social activities should be the first priority.

这个例子中believe是动词，belief才是名词形式。虽然发音相近，但是用法却完全不同。
