51、已經(jīng)有100多架飛機起飛了”。由此可推斷，問句問的是“每年有多少人旅游”，故所缺的特殊疑問詞是how many。II. 完形填空。1. B。此處所缺的詞是it，it指代“a new middle school”。2. A。由其后的one is for studying，and the other one is for living可知，我們有兩棟樓，故two符合題意。3.

I have to stay at home. 正在下雨，我不得不待在家里。(2) must側(cè)重于說話者的主觀看法，認為有必要或有義務(wù)去做某事；只有現(xiàn)在時一種形式（在賓語從句中可以表示過去）；否定式mustnt 意為“一定不要；不允許”。例如： You must do your homework first. 你必須先做作業(yè)?？谠E：“主觀職責”說“必須”，must趕緊用上去；若是“環(huán)境”“不得不”，趕緊換用have to。3.

60、例如：Thanks for helping me. 謝謝你幫助我。Not at all. I enjoyed it. 別客氣，很高興能幫你。5. If there is a fire or someone calls 911, we have to stop everything and get out fast. if在此處作連詞，意為“如果，假如”，引導條件狀語從句。例如： If you think hard, you can find a way. 如果你努力思考，你可以想出辦法的?！就卣埂吭诤衖f引導的條件狀語從句的主從復合句中，如果主句用一般將來時，從句應用一般現(xiàn)在時表示將來，即“
