不可以,強調(diào)句中的這兩個連詞是絕對不能省略的.His writing is so confusing that it's difficult to make out what it is he is trying to express.這是安徽省2011年高考題，為什么what it is后面沒有that?這不是強調(diào)句嗎？這個不是強調(diào)句。首先一個so...that 句型，這個你應(yīng)該看明白了。接下來是個it is + adj+to do的句型what it is he is trying to express 這是個定語從句，本來的句子應(yīng)該是：he is trying to express is what，it 這里是個代詞代替he is trying to express.這句話的；由于這個句子又要做make out 的賓語從句，把本來的特殊疑問句 what is it？變成了賓語從句的陳述語序，就出現(xiàn)了what it iswhat it is he is trying to express 我覺得這個是賓語從句吧，做make out 賓語；如果是定語從句，沒有先行詞。嗯，我理解錯誤了。應(yīng)該是這樣理解才對，it作為形式主語代替后面的句子he is trying to express,那么這個賓語從句就是 what he is trying to express is.
