gwd31-4- 34,C选项是run on 吗?

Q34:

The market for recycled commodities like
aluminum and other metals remain strong despite economic changes in the
recycling industry.

1. commodities like aluminum and other metals remain
2. commodities like those of aluminum and other metals are
        remaining
3. commodities such as aluminum and other metals remains
4. commodities, such as aluminum and other metals, remain
5. commodities, like the commodities of aluminum and other metals,
        remains

   Answer:E

The market for recycled commodities like
aluminum and other metals remain strong despite economic changes in the
recycling industry.

 一 RUN ON的句子，中间部分明显是个插入语，有时是主语的同位语，肯定是需要两个逗号隔开，A、B、C错。

二 然后market是单数主语，谓语用 remains，A、B、D错
三  而且B中的like those 是个错误答案标志。

I think C is right. It's not a run on.

The aluminum id one of the recycled commodities

同意C. E的like不能用来举例, OG里说过的.

E 错

C

E的like做什么解释都是错的

1.像：和market概念不对等

2.举例：错误用法，应该是such as

Longman:

Cartoon characters such as Mickey Mouse and Snoopy are still popular.

看来Such as前后不一定要用逗号分开。
