会计考友

一些特殊的句型  
　　1) there is no point in doing sth.
, C( d) @* ]7 |# K  f　　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。
9 p/ v& w' z# H  |7 X) n- N9 R+ u　　There is very little point in arguing with him.
0 O5 s9 P; ~$ M* A% D　　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。
" `% u9 s3 ]4 r) \, @& F  i8 j% Z) g　　There was little difficulty in finding him. www.Examw.com
# u; \+ v8 D5 h4 W1 C# V& J' A　　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.。
6 t3 }$ U: U$ a6 i. _　　We are busy preparing for the examination.
　　4) feel like doing sth.
4 _% l! Y5 t2 z# \7 D　　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”。
* ~: ], V4 |/ K" l: |3 u1 ^　　I was so angry that I felt like throwing something at him.
　　I feel like beer tonight.
