for 与of 的辨别方法：

用介词后面的代词作主语，用介词前边的形容词作表语，造个句子。如果道理上通顺用of，不通则用for。如：

You are nice. (通顺，所以应用of)。

He is hard. (人是困难的，不通，因此应用for。)

9) 对两个句子的提问

新目标英语在命题中有将对句子划线提问这一题型取消的趋势，现在采取的作法是对一个句子进行自由提问。例如：

句子：The boy in blue has three pens.

提问：1.Who has three pens?

2.Which boy has three pens?

3.What does the boy in blue have?

4.How many pens does the boy in blue have?

很显然，学生多了更多的回答角度，也体现了考试的灵活性。再如：

句子：He usually goes to the park with his friends at 8:00 on Sunday.

提问：1.Who usually goes to the park with his friends at 8:00 on Sunday?

2.Where does he usually go with his friends at 8:00 on Sunday?

3.What does he usually do with his friends at 8:00 on Sunday?

4.With whom does he usually go to the park at 8:00 on Sunday?

5.What time does he usually go to the park with his friends on Sunday?

6.When does he usually go to the park with his friends?

so、such与不定冠词的使用

1.so与不定冠词a、an连用，结构为“so+形容词+a/an+名词”。如：

He is so funny a boy.

Jim has so big a house.

2.such与不定冠词a、an连用，结构为“such+a/an+形容词+名词”。如：

It is such a nice day.

That was such an interesting story.

11) 使用-ing分词的几种情况

1.在进行时态中。如：

He is watching TV in the room.

They were dancing at nine o'clock last night.

2.在there be结构中。如：

There is a boy swimming in the river.

3.在have fun/problems结构中。如：

We have fun learning English this term.

They had problems getting to the top of the mountain.

4.在介词后面。如：

Thanks for helping me.

Are you good at playing basketball.
