在英语中，有些动词若只带一个宾语，句子的意义还很不完整，须另带一个成分来说明宾语的情况或状态，这个成分叫作宾语补足语，简称宾补。作宾补的一般有：名词、形容词、动词不定式及动词-ing形式和动词-ed形式等。1）His father named him Daming. 2）They painted their huse white.3）Yu mustn’t frce him t lend his mney t yu.4） We saw her entering the rm. 5）We must get the wrk finished by 10 ’clck. 6）We take English as a useful tl fr research wrk. 7）Let the fresh air in.
1．v­ing形式作宾语补足语 v­ing形式作宾语补足语时，宾语与宾语补足语之间在逻辑上是主谓关系。能接v­ing形式作补语的有两类动词：(1)感觉、感官类动词：see, ntice, watch, lk at, hear, listen t, find, feel, smell等。【例句】He heard the wind blwing utside. 他听到外边在刮风。【例句】I felt my heart beating faster. 我感到我的心跳得更快了。(2)使役动词：keep, get, leave, have等。【例句】I’m srry t have kept yu waiting fr s lng. 不好意思让你等这么久。【例句】The captain gt the sldiers mving tward the frnt after a shrt rest. 休息了片刻之后，上尉让士兵们朝前线行进。
2．v­ed形式作补语 v­ed形式作宾语补足语既可表示被动又可表示动作已经完成；宾语与宾语补足语之间在逻辑上是动宾关系。 v­ed形式作补语的常见情况：(1)位于feel, find, hear, ntice, see, smell, bserve等感官动词后作补语。【例句】She was glad t see her child taken gd care f. 她很高兴看到自己的孩子被照顾得很好。【例句】I was sleeping when I heard my name called. 我正在睡觉，这时听到有人喊我的名字。(2)位于get, have, make, keep, leave等使役动词后作补语。【例句】They are ging t have the huse painted white. 他们准备把房子刷成白色。
3.表示“意欲; 命令”的动词如: like, rder, want, wish后, 表示“希望、要求某人或某事被做”。【例句】The father wants his daughter taught the pian. 这位父亲想让他的女儿学钢琴。 【例句】I wish these letters typed as sn as pssible. 我希望这些信件能尽快(被)打印出来。
4. with复合结构中作宾补的非谓语动词 “with＋宾语＋宾补”结构可在句中作定语或状语(表示原因、时间、条件、伴随、方式等)，宾补可以是名词/形容词/副词/介词短语/现在分词/过去分词/不定式。 在此我们重点讲解宾补是分词和不定式的情况。(1)with＋名词/代词＋现在分词。现在分词可表示主动和动作正在进行。【例句】He lay n the grass with his eyes lking at the sky. 他躺在草地上，眼望着天空。(伴随状语)
(2)with＋名词/代词＋过去分词。过去分词可表示被动和动作已完成。【例句】With his hair cut, he lked much yunger. 理了发，他看起来年轻多了。(原因状语) (3)with＋名词/代词＋不定式。不定式表示动作尚未发生。 切记：不定式一般情况下都用主动形式。【例句】With a lt f hmewrk t d, I can’t g skating with yu. 因为有很多家庭作业要做，我不能和你一起去滑冰了。(原因状语)
