第一行:
child→children their 是他们的,所以孩子不止一个,要用复数.
for→because,for是介词,不能接句子,所以用Because.
第二行:
To begin with→on the one hand To begin with的意思是首先,本来,用在这里不合适
meanwhile→on the other hand ,一方面,另一方面,这样用比较贴切
第三行:
child→children 谓语动词是复数,所以对应主语也应该是复数形式
第四行:
have→has,a smart phone 是单数,所以谓语也用单数has
第二段第三行:
listening →listen do sth rather than do sth前后动词形式要保持一致
第四行:
very前加a,那是一个严重的问题;
the radiation of call phone is huge is issue to children 改成:the radiation of call phone is a huge issue to children
第五行:According to recent reports ,在to之后加不定冠词the
倒数第三行:would→will 或者can
最后一行:make →let be→stay
