学英语很多同学最怕的就是学语法，记不住不说，一记就脑袋瓜疼，但是没办法，考试要考怎么办，还得印着头皮往下学，下面我们就语法的一些常见问题，来简单介绍几点，看看你自己是不是也经常犯这种错误。
1.句子成分残缺不全
(1) We always working till late at night before taking exams.（误）
错误点：谓语动词形式不完整，要么用 are working； 要么直接用过去式 worked
改：We are always working till late at night before taking exams.
或 We always work till late at night before taking exams.
(2) We should read books may be useful to us. （误）
错误点：出现了双谓语（缺少从句引导词）
改：We should read books which may be useful to us.
2.句子成分多余
(1) This test is end, but there is another test is waiting for you. （误）
错误点：but 前面这句is end 两个动词无法并存； but 后面这句出现两个 is
改：One test ends, but another is waiting for you.
(2)The driver of the red car was died on the spot. （误）
错误点：was和 died 两个动词过去式无法并存。
改：The driver of the red car died on the spot.
3.主谓不一致
(1)Someone think that reading should be selective. （误）
错误点：someone 第三人称单数，动词不能用原型 think
改：Some think that reading should be selective.
(2) My sister go to the cinema at least once a week. （误）
错误点：sister 和 go，主谓不一致（动词没有调成第三人称单数）
改：My sister goes to the cinema at least once a week.
4. 动词时态、语态的误用
(1) I was walking along the road, and there are not so many cars on the street. （误）
错误点：前句 was walking 已经设定时间为过去，and 后面 are 仍是现在时，不对。
改：I was walking along the road and there were not so many vehicles on the street.
(2) The meeting has canceled.（误）
错误点：会议应该“被取消”，这里应该用被动语态
改：The meeting has been canceled.
5.词类混淆
(1) An old man is across the road. （误）
错误点：across介词使用错误，be across 表示“在…对面”。
改：The old man is crossing the road. （正）
(2)She studies hardly, so she got a high score in the exam. （误）
错误点： 因为后句说她考试取得高分，所以前面一定说她努力学习。hard 本身有副词属性，表示“努力地”，studies hard 才是“努力学习”，而hardly 表示“几乎不”，意思正好相反了。
改：She studies hard, so she got a high score in the exam.
