一些特殊的句型  
' j$ \* o8 m5 x$ T* U　　1) there is no point in doing sth.
　　该句型意为“做…是无济于事的/没有什么用的”。可以用very little 或not much等来代替no。其中的point是不可数名词，作“目的”、“用处”解。
' a2 b# b$ q) F: D# I6 x9 B; ~, h　　There is very little point in arguing with him.
6 {8 q, {8 n$ Q% t- n5 y　　2) have difficulty (or trouble) in doing sth.
　　该句型意为“做…有困难”。其中的in可以省略;其中的difficulty和trouble是不可数名词，不能有复数形式。也可以用there is difficulty(or trouble) in doing sth.表达相同的意思。
& R" _% B7 u+ q1 j! w　　There was little difficulty in finding him. www.Examw.com
　　3) keep (sb. or sth. ) busy doing sth.
　　该句型意为“使…一直忙着做某事”。需注意的是虽然busy with doing sth.和busy in doing sth.都是正确的，但考题中常考busy doing sth.句型。但如果busy后面跟的是名词，则要用busy with sth.。
　　We are busy preparing for the examination.
/ J: S9 S* x; o* o9 Z( `　　4) feel like doing sth.
　　该句型意为“想做某事”，且feel like后只能跟动名词，而不能跟动词不定式。此外，feel like后还可跟名词或代词，表示“想要某物”。
$ V9 I' T9 Q$ @8 \. s9 t$ e, C: P　　I was so angry that I felt like throwing something at him.
0 O8 W. n) T+ Z+ T* B　　I feel like beer tonight.
