在ACT英语中，很多同学傻傻分不清楚的"分号"和"句号"。下面我们通过几个例句来讲解一下"分号"和"句号"的功能。

1.分号和句号可以连接两个完整的句子。

Mike ate five brownies; Eileen ate seven.

Jack needed to buy peas; he ran to the market.

2.分号和副词一起，连接两个完整的句子。

Mike ate five brownies; however, Eileen ate seven.

Jack needed to buy peas; thus he ran to the market.

考试中常见的副词有：consequently, however, furthermore, moreover, nevertheless, therefore.

3.分号不可以隔开以but, because开始的句子。

Hank finished studying for the ACT; but he still had to take the test.

Hank finished studying for the ACT; he still had to take the test.

乍一看，这两个句子很相似。第一句分号后面紧跟了一个but开头的句子，这是错误的，因为分号的功能相当于句号，这里的but是多余的。所以第二句正确。这个考点希望大家要牢记。分号不可以隔开以but, because开始的句子！分号不可以隔开以but, because开始的句子！分号不可以隔开以but, because开始的句子！

以上是有关分号和句号的易错考点，下面通过三道题目再来加深一下理解吧！

例1: As you start to familiarize yourself with new exam, we are excited to share with you some of the many benefits it has to offer.

A.NO CHANGE

B.. we

C.; we

D.: we

解析：逗号前后是主句和从句的关系，所这里使用逗号是正确的。选择A。

例2: The world needs more young talents who can solve problems, communicate clearly; and understand complex relationships.

A.NO CHANGE

B.clearly,

C.clearly.

D.clearly:

解析：本题考查的实际是逗号的用法，通过分析，我们可以发现solve problems, communicate clearly和understand complex relationships是三个并列的短语，故这里应用逗号，选择B。

例3: ACT test results show scores in different context. Several of the scores describe the same parts of the test in different ways or combinations.

Which answer is not acceptable?

A.NO CHANGE

B.; several

C., several

D., and several

解析：这道题目童鞋们需要擦亮自己的双眼，看清出问题是：哪个答案是错误的？题目中的句号前后都是两个独立的句子，所以分号和句号都是正确的，排出A和B。D选项中多了个and，连词可以连接前后两个句子，所以也是正确的。C中的逗号是错误的，因为逗号不可以连接连个独立的句子。重要考点！正确答案是C。
