英语句首的逗号

英语逗号的用法：

用逗号连接两个句子的时候，必须加连词，因为一个主句不能有两个谓语，除非加了连词把它变成并列句或者主从句

如果想把这个句子继续写下去但又不想加连词，还可以加分号，这两个半句之间没有连接关系但依然是一句话。因为加了分号之后这两句还是一句话，所以分号后面不用加主语。

除此之外就得加句号。

汉语中逗号的用法：

1、句子内部主语与谓语之间如需停顿，用逗号。

例如：我们看得见的星星，绝大多数是恒星。

2、句子内部动词与宾语之间如需停顿，用逗号。例如：应该看到，科学需要一个人贡献出毕生的精力。

3、句子内部状语后边如需停顿，用逗号。

例如：对于这个城市，他并不陌生。

4、复句内各分句之间的停顿，除了有时要用分号外，都要用逗号。例如：据说苏州园林有一百多处，我到过的不过十多处。

5、用来分开句内各词语或表示语气的停顿。提示：“，”不可放在一行之首或开头。

6、并列词语之间带有“啊”“呀”“啦”等语气助词时，并列成分之间用逗号，不用顿号。例如：八月的大街上摆满了水果，像甜瓜啊，西瓜啊，苹果啊，葡萄啊......

7、并列成分做谓语时，如果并列成分是主谓结构，那么并列成分之间用逗号。例如：她衣服新潮夺目，头发齐耳根长，走起路来风风火火，讲起话来大声大气。

1、逗号后面可以是一句话，逗号成分要齐全。例如：he came here and had a look----he came here ，and he had a look。用法与此类似的还有but or yet 等等。

2、逗号用来表示一个句子中的简短停暂.逗号的使用不能大意，因为一个错位的逗号可以改变整句话的原意。例如：

James hit Lane, and Edward, then ran away. 詹姆斯打了莱恩和爱德华,然后跑掉了.

James hit Lane, and Edward then ran away.詹姆斯打了莱恩,然后爱德华跑掉了.

3、用逗号来分开两项以上物品。在一个清单（list）中,如有超过两项以上物品,要用逗号将其分开。例如：’cars, trucks, vans, and tractors’. 在van之前加上一个逗号来区别tractor和其他车辆不是同一类的。

4、在形容词之间加上逗号（如果每个形容词用相类似属性修饰其管辖的名词）.例如：’a small, dark room’. 不过,但形容词用不同属性修饰其管辖的名词时,就不需要使用逗号.例如：’a distinguished international lawyer’ 或 ‘a shiny blue suit’.

5、逗号用于插入语中，可以将句子的成分隔离开来，逗号里面的成分作为补充说明。例如：He ，a student from high shool，finally won the contest.

您好，（逗号）在英语句子中的确可以充当（连词）的用法，尤其是（并列连词）and。（逗号）通常也可以用来区分（分句）结构，用于（列表）结构，还可以用来区分比如（状语），和（插入语）等在句中的使用。但在正式的书面语中，通常会尽量避开这种不规范的使用方式。

您提供句子中，第一个逗号是区分（时间状语）和（主句），通常来说，状语作为句首，的确会使用逗号划分，但出现在句尾，就不会用到逗号；从句结构也是如此，出现在句首，会用逗号将主句划分，但出现在句尾，就不会用逗号。

第二个逗号，是区分第一个分句 the recovery of the world economy remains weak 和 第二个分句 global trade and investment are sluggish；而第三个逗号是区分第二个分句和第三个分句 commodity prices continue to fluctuate.

频繁的使用并列连词 and 连接分句，或是列表时，很容易导致混淆，尤其是 and 用于并列主语、并列谓语、并列宾语，和并列句子时，要是多个 and 出现了，很容易造成不确定性。比如您的句子要是不使用第3个逗号，按照常规会是：

At present, the recovery of the world economy remains weak, global trade and investment are sluggish and commodity prices continue to fluctuate.  把第三个逗号改成 and 还不会发生混淆，因为句子的主系表和主谓宾结构很清晰，但要是把第二个逗号也改成 and，那就不一定了。

At present, the recovery of the world economy remains weak and global trade and investment are sluggish and commodity prices continue to fluctuate。

此时的 and global trade and investment are lusggish and commodity 就有3个 and 了，并列时容易出现混淆了，因为 and 是用来并列主语的，还是用来并列谓语的，还是用来并列分句的就较难区分开来了，而且读起来很变扭。所以这种情况发生时，是可以采用直接使用（逗号）作为连接（分句）的省略了 and 的模式的。

（逗号）的另一个用处就是让（读）的人可以停顿，吸口气，继续读下面的句子。原句的3个逗号，可以分为4口气，而且每一次的停顿都是一个完整的状语，或是完整的句子，听的人较为容易理解。假如把 and 加回去，去掉了（逗号），那么停顿就需要靠读的人的智慧了。假如停顿发生在分句的句中，而把（什么and什么）之间没有停顿，很容易让听的人误解，或是无法理解到底想要说什么，比如中间部分，按照大部分的人的习惯会读成 remaisn weak 停顿 and global trade 停顿 and investment 停顿 ar sluggish 停顿 and commodity prices 停顿 continue to fluctuate. 此时 and global trade 和 and investment 很难知道他们是并列主语的关系，而会把 and global trade 变成了和 the recovery 并列了。

所以（逗号）的出现在一定程度上是希望读的人可以一口气读完逗号之间的分句，然后再继续下个分句。希望这样的解释可以帮到您。

英文逗号叫做 comma，用来分隔一个句子的组成部分或者列举的事项。前者等同于汉语的逗号，后者相当于汉语的顿号。
