Answer 1

分析 if you always stay up late，you will be too tired to pay attention to what the teacher says．

解答 答案：if you always stay up late，you will be too tired to pay attention to what the teacher says．．這里需用if引導(dǎo)的條件狀語從句表示如果…，遵循主將從現(xiàn)的規(guī)則，主句是一般將來時will+動詞原形，主語是you，表示太…以至于，用too…to do sth，累了用tired，故you will be too tired to，注意用pay attention to后加賓語老師講的內(nèi)容，用賓語從句來表達(dá)，也就是老師說了什么，what是連接詞，主語the teacher 謂語用三單says，故you will be too tired to pay attention to what the teacher says，從句是一般現(xiàn)在時，主語是you，熬夜stay up late，加上頻率副詞always，故if you always stay up late，故答案是 if you always stay up late，you will be too tired to pay attention to what the teacher says．

點評 這里是復(fù)合句的呈現(xiàn)，課下多做一些復(fù)合句的聯(lián)系，孰能生巧．
