冠詞
7. The boss wants to hire an useful person.
用a還是an,取決于后面單詞的第一個音標,如為元音用an,為輔音用a。useful的第一個音是輔音所以應把an改為a。類似的,我們說a European country.
8.Plane is a machine that can fly.
Plane為可數(shù)名詞單數(shù),不能單獨放在句中,應在其前加冠詞或把它變?yōu)閺蛿?shù),而本句后有a machine, 因此只能在其前面加a,變?yōu)锳 plane。
9.He played a piano at the party yesterday.
把a 改為the ,因為樂器前用定冠詞。
10.The machine was invented in 1920s.
在in后加the,因為表示年代用in加the再加幾十的復數(shù),如在八十年代in the 80s。
11.Xiao Hong went to school by the bus every day.
去掉the,因為表示交通方式用by直接加交通工具。
代詞
使用代詞時請注意其單、復數(shù),主、賓格以及形容詞性物主代詞和名詞性物主代詞的用法。
12.He is one of those speakers who make his ideas perfectly clear.
定語從句的先行詞是those speakers,為復數(shù),因此從句中的指示代詞應為復數(shù),應把his改為their。
13. Whom do you think has left the lights on?
放在疑問句特殊疑問詞后的do you think / believe / guess / imagine / suppose等都不參與句子成分,把它們?nèi)サ艉螅蓡栐~在句中做主語用主格,做賓語用賓格。本句中去掉do you think后缺的是主語,應把Whom改為Who。
14.The boss pretended not to see John and I.
John和I在句中都做的賓語,應把I 改為me。
15.These books are mine; those in the bag are her.
Her是形容詞性物主代詞,后面應該加名詞books,或把her 改為hers。
