The sun _(go) down to the west.解析:本題考查正確填寫動詞的形式。在做這類題的時候，要先判斷句子的時態(tài)。第1、2小題分別體現(xiàn)經常性和習慣性，應該用一般現(xiàn)在時，而he是第三人稱，故動詞要用三單形式，助動詞用does; 第3小題太陽西下是自然規(guī)律，用一般現(xiàn)在時。 答案：1. gets 2. do

8、 go swimming in summer. (就畫線部分提問)_ 解析:本題三個句子都是一般現(xiàn)在時，在變否定句或一般疑問句的時候，我們要考慮借助助動詞do或does。第1 小題主語Lucy and Lily 是復數(shù)名詞，否定句加 dont, 要注意的是usually在否定句中要置于助動詞之后，實義動詞之前，或者也可以用否定詞never 來整句改寫；第2小題Mike是第三人稱的主語，要用Does開頭，其后的動詞要用原形；第3小題中的go swimming是動詞詞組，也就是“做什么”的問題，用“What do”的形式提問,同時注意we 要改成 you。 答案：1. Lucy and Lily
