advices最好改成advice
因为：
1.表示“劝告”、“忠告”、“建议”,是不可数名词,若要表示一条或几条建议或劝告,则说a piece / three pieces of advice 一条 / 三条建议.2.表示按照某人的意见做某事,一般用介词on 或by.如：It was done on (或by) my advice.这是按我的意见做的.3.表示提出建议或忠告,一般用动词give；表示向某人请教或征求意见,一般用动词ask / ask for; 表示接受意见或劝告,一般用动词take / follow.如：He gave us good advice on how to learn English.他对怎样学习英语给我们提出了很好的建议.He asked (for) the teacher’s advice./ He asked the teacher for his advice.他向老师请教.If you take (或follow) my advice and study hard,you’ll pass the examination.如果你听我的劝告用功读书,你就会考及格.
accepted 改成received,应该是收信而不是接受信,注意区别两个词的用法：
receive指“收到”,着重“行为本身,而不涉及收受者是否接受”,如:
I received an invitation.
我收到了请帖.
accept 指“领受”,“接收”,着重“除行为本身以外,还表示接受者经过考虑以后愿意接受”,如:
I accepted the invitation.
我接受邀请.
改：you must be able to
able不是动词,而是表语,所以这个句子少了谓语动词,要加进去.
Beside改Besides
beside (=next to) 例句He sat down beside Mary.
besides (=in addition to) 例句Who was there besides you?
这里的明显不是next to的意思,而是“另外”的意思.
a good teacher should do what he can act what he is teaching to make its meaning clear .这句很有问题.给你改成“a good teacher should do what he can to act (out) what he is teaching in order to make its meaning clear.”
一个好的老师应该尽其所能表演出他正在教的东西以便于其意思清晰.
before their class 没问题,但是我会用in front of their class
may not be able to acting well on the stage 中的acting改成act
to后面跟动词原型.
the ac-tor 改成 the actor's.
前后要一致,是工作与工作之间的差别,the actor's后面省略了work,避免重复.
OK,完了,累死我了,希望能帮到你吧.
