4.For example, I think more and more people will immigrate to another country(/other countries).

5.They do not like to live in Hong Kong.[okay]

6.Dirty environment could impose negative impact on people, such as getting ill easier.
[Bad的定義太廣了
have係擁有.而environment沒有擁有不良的影響
such as後面不能有verb.所以get要加ing令佢能變成phrase]

7.Our health and life will be threatened.
[我們的健康同生命怎會是危險的呢?被威脅會比較正確]

9.We should face this problem positively.[okay?but sorry.i am not sure about this sentence]

4.I also like to go to the library with my classmates.
[moreover同also意思一樣.唔洗一齊用]

5.We can read more books in the library and hence gain more knowledge.
[我估你的 是跟在家或其他地方閱讀比較.若不.意思就會有點奇怪]

6.Certainly, when I encounter any problem in studying, I will ask teachers for help.
