唉没办法英语就是差!
——Shall I guide you through the streets to the railway station?
——A.It's over there B.Of course you can
C.You'd better think it carefully.
D.It couldn't be better
就是不敢确定,guide you through 看起来C、D好像都不对,
哦是这样骂？我一直也为D是不好的意思呢
怎么了，你不相信么？我就只么个水平罢了，单选就没语感了，初中最多错两个，现在一错十几个，最少5个，我该咋办，每次考试都只有110左右，什么时候才能回到以前的130呢？
