第一易错点：
Government claims that teacher should teach student some self-protection skills.
错误分析：可数名词不可“裸用”。
在正式英文写作里，凡是常规的可数名词，必须在前面有限定词，比如冠词a/an/the，物主代词my/their/your等等，指示代词 this/that等等。否则，这个可数名词就必须用复数。而在这个句子中government要么用the government，要么用government，后面的teacher和student都一样要加上复数。
因此，这个句子要改成：The government claims that teachers should teach students some self-protection skills.
第二易错点：
Work at home using modern technology can greatly enhance our efficiency.
错误分析：英语中动词原形是不能作主语的，而且在这个句子中如果work做了动词，后面can enhance也是动词，就出现双谓语的情况，因此把work改成working.
因此，这个句子要改成：Working at home using modern technology can greatly enhance our efficiency.
第三易错点：
Intelligent students should not be treated different by their teachers.
错误分析：词性使用错误。
different的词性为形容词，而修饰形容词或者动词的时候应该用副词。
因此，这个句子要改成：Intelligent students should not be treated differently by their teachers.
第四易错点：
A lot of houses were collapsedin the earthquake.
错误分析：句中出现双谓语。
句中collapse已经为动词，再加be动词之后就变成了被动结构，此处be纯属多余。
因此，这个句子要改成：A lot of housescollapsedin the earthquake.
第五易错点：
Some parents do not obey traffic rules himself.
错误分析：当我们用到代词的时候，就一定要看所指代的名词的单复数，根据名词的单复数来使用相应的代词。
因此，这个句子要改成：Some parents do not obey traffic rules themselves.
第六易错点：
Letters were the most important way of communication in the past , e-mail becomes its biggest rival now.
错误分析：这个句子的句型并不属于简单句、并列句、或者复合句中的任何一种的定义。因为出现了两套动词，因此我们可以将这个句子变成并列句，而前后两句之间是对比关系，所以我们可以在中间加对比连词或副词，比如while。
因此，这个句子要改成：Letters were the most important way of communication in the past while now e-mail becomes its biggest rival now.
第七易错点：
There are a great deal of people go abroad every year.
错误分析：当我们用到there be句型的时候，后面不能再出现动词原形。因此要将go变换形式，改为going，或者将句子转换为定语从句，在people后面加上who。
因此，这个句子要改成：There are a great deal of people going abroad every year. 或There are a great deal of people who go abroad every year.
