1.应该说so beautiful a girl或者such a beautiful girl2.the number of the students in our class is 55 and there are a number of students are girls.这个是错误的前句The number of the students in our class is 55 我们班有55名学生 这个是对的后面and并列句 there are a number of students are girls 有两个谓语是错误的有一些是女生,或者可以这么直接表达:a number of students are girls 整句就是:The number of the students in our class is 55 and a number of students are girls.3.是在元音前加anaward[ə'wɔ:d] 发音是元音,用anan award4.end也可以做名词,表示末端,尽头 the end of 是可以的5.应该不可以比如:I was cooking in the kitchen when someone knocked at the door. 我正在厨房做饭,这时有人敲门。主句中可以用进行时 when做并列连词,意为“在那时,届时”,表示时间。 while可以主句和从句都用进行时
