那这些为什么要这样写呢？
1.Thank you for you_kindnessd)
2.That river is 3000 metres in length (long）
3.His father owns (own)some stores in China
4.We shuold keep healthy (health)
5.His dream is to be_(be)an engineer
为什么是这样写的

Answer 1

1.Thank you for you_kindness
Thank you for your kindness. 语法是"thank you for sth/doing sth"，物主代词修饰名字。
2.That river is 3000 metres in length (long）
That river is 3000 metres in length. 如果要用long的话应该是3000-metre long
3.His father owns (own)some stores in China
His father owns some stores in China. 第三人称单数
4.We shuold keep healthy (health)
We shuold keep healthy. keep + adj 保持什么样的状态，keep sth 保留某物
5.His dream is to be_(be)an engineer
His dream is to be an engineer. 主谓宾，主语是his dream，谓语是is，宾语不能使动词，所以用介宾短语to be来替代be。完整的一句话里面（没有连词的连接成分）只能有一个动词。

Answer 2

1.Thank you for you_kindness)
2.That river is 3000 metres in length (long）
3.His father owns (own)some stores in China
4.We shuold keep healthy (health)
5.His dream is to be_(be)an engineer
1题目上最后应该是your 所以后面的是名词形式
2【in length】在长度上 固定词组
3第三人称单数
4【keep healthy】keep后面加形容词 保持健康
5【is to be】表示将来
有不会的可以再问我
