1.the film is very nice.it's very 【exciting】.(excite)
修饰【 film】,表示事物,用-ving演变的形容词.
2.这个句子少打了个从句的主语:
We will go for a picnic if【it】 _ rain tomorrow.A isn't B.doesn't C.won't D.wasn't
选B,doesn't.
时态搭配原则:
主句用一般将来时,时间、条件状语从句要用一般现在时代替一般将来时.
根据这一搭配原则,直接排除C,D.
根据空后面的词形动词原形【rain 】,排除A.
所以,选B.ben wants to investigate how yogurt is made,he needs to _ somenoe at s daityA.visit B.see C.find D.interview你最好查证一下,先把问题给准确——问题最后肯定有错漏词,这会很影响判断的。
