学会“abound”这个词，就可以愉快告别“there are a lot...”和“be full of”了。

今天的10个句子点评：

1. Phenomena of students cheating in exams in today's universities abound, but I am bound to stick to my principles.

点评：出淤泥而不染。怒赞！

2. By watching the hit India movie, I realize that sexual discrimination also abound in our society.

点评：意识很好，建议加上电影名称《摔跤吧，爸爸！》，让句子更具体。同时，注意词性、时态和主谓一致：

By watching the hit Indian movie Dangal, I realized that sexual discrimination also abounds in our society. 

3. Colorful bikes that users can rent on demand with a smartphone app and then park wherever they choose abound on the city streets around the country.

点评：很棒的句子，一句话描述清楚了共享单车的机制。这样调整视觉上更好：

Colorful bikes, which users can rent on demand with a smartphone app and then park wherever they choose, abound on the city streets around the country.

4. Rumors abound as to the reasons for President Trump fired former FBI director Comey.

点评：这个句子照顾到了美国政治热点。可以写得更简洁：

1) Rumors abound as to the reasons President Trump fired former FBI director Comey.

2) Rumors abound as to why President Trump fired former FBI director Comey. 

5. Since South Korea has planned to build missile-against system, which could protect the area from missile attack, protests from China abound.

点评：意识很好，但“反导弹系统”的英文表达有点想当然了，同时背景可以写得更完整一些。这样改写：

Since South Korea has planned to build a missile defense system, which could protect the area from missile attack but pose security threats to China, protests from China abound.

6. The articles on Mother's Day abound in my Wechat Moment today.

点评：很应景，“abound”确实可以有“刷屏”的意思。Good job!

7. Although English-learning materials abound, chances are slim that English can be mastered without perservance and hard work.

点评：很棒的句子。“chances are slim that”是很好用的句型，值得学会。“英语学习资料”可以说“learning materials for English”或“materials for English learning”.

8. Frauds by mobile messages abound in our country. / In Shenzhen migrant workers abound. / Nowadays government corruption abounds in China.

点评：这是三个读者写得句子，因为都比较简单所以就放在一起了。这一定程度上可以说明“abound”这个词有多好用，也是我做“每日一词计划”和选词的初衷。

9. Bangbang brigade abounded during the 1970s in Chongqing.

点评：作者是重庆人？这句中写的是重庆的棒棒军，我是读何伟的《江城》才知道这个群体的。建议“bangbang brigade”加引号，因为英文中本身没有这个表达。

10. Metropolises such as Beijing and Shanghai abound with job opportunities.

点评：“abound with”就相当于“be full of”. 不管是在口语还是写作中，这个表达都比“There are many...”和“be full of”更优。

到现在已经练习了四个精选词（vary, count, remain 和 abound）, 有没有觉得自己的表达能力突然间提升了一截？
