英语语法，哪些句子有错误？怎么改？最好的句子是哪一句话，为什么？

Question

1，Many goods online have quality problems.
2，Many things on tne Internet have quality problems.
3，the quality problem of a greatmany bargains exists.
4，The goods online may be with plenty of quality problems.
5，Many things online have problems in quality.
6，things online ofen have quality issues.

Answer 1

1.第一句在保持其本身特色的条件下最佳方案应该为Many on-line goods have quality problems.（on-line作后置定语勉强可以算行，但是不如说on-line goods好）
2.此句没错。
3.词句在保留自身特色时应该为There exists quality problems in a great many bargains.或者是The quality problems exists in a great many bargains.
4.此句应该为The on-line goods might have plenty of quality problems.
5.Many on-line goods/commodities(网上的“东西”不说things) have quality problems(problems in quality也行，但是不地道).
6.Things on-line often have quality problems.(issue在这里不合适，还是应该用problem)
最好的“一句”是改正过的Many on-line goods have quality problems以及第二句。这两句都是很好的。

Answer 2

1. 可以这么说，不算错
2. 正确，无可挑剔
3. 语法错误，逻辑错误，思维混乱，不知所云
4. 可以这么说，但不够好，最好说 may have plenty.......
5. 正确
6. 我认为是不小心，少输入词了，应该是 Many things online often have quality issues. 所以也正确。

Answer 3

1. 错，因为online 是一个形容词，不是副词。
2. 对。
3. 错。语言顺序不对，没人这么说话。而且，bargain是特价商品的意思。
4. 错。道理同1。
5. 错。道理同1。
6. 错。online 错，issue 错。issue 常常指有争议的问题。追问

不好意思，我想再问一下：第1，3，6怎么改？？

追答

1. Mnay goods on the Internet have quality problems.
3. The quality problem with a great many goods does exist. (这种句型，在此处最好强调；不
强调就用exists. 不过，有点别扭。）
6. Things bought on the Internet often have quality problems.
