1.C
滑草是一种新兴的娱乐形式,深受年青人欢迎.在这种娱乐活动中,草地上的滑行即惊险又好玩.
定语从句,修饰先行词a rising form of entertainment.
将这个先行词代入后面的定语从句中,明显需要加介词in,然后in a rising form of entertainment一起在该从句中充当引申的地点状语.
定语从句中,sliding on the grass是主语,could be adventurous and enjoyable是系表结构做谓语,地点状语in a rising form of entertainment.
A who只能代替指人的先行词,但是a rising form of entertainment明显是物；
B whose在定语从句中必须修饰名词做定语,不妥；
D when在定语从句中充当时间状语,排除.
2.C
翻译：巴西在谷类能源的投资很成功,10%的燃油供应由谷类能源提供是其当前目标.
根据句意,and后面是一个并列句：------ten percent of its oil supply with grain energy is its current goal.
这样,------ten percent of its oil supply with grain energy是该句的主语,后面是系表结构is its current goal.
英语句子中,动名词短语可用做句子主语,所以答案是C.
AB必须在句中充当谓语,排除；
D不定式虽然也可以做句子主语,但是句意为主动,不能使用被动结构to be done,排除.
3.A
翻译：瑞士的收入差距比其它欧洲国家的要小很多,（这就）确保了瑞士的社会稳定与和谐.
根据句意,逗号后面为结果状语.
英语中,如果表示根据句子谓语动作顺理成章所导致的结果,一般用现在分词（短语）充当该结果状语.
B为过去分词表示被动或做一般过去时句中的谓语,排除.
C为动词的三单形式,做句子谓语,不能做状语,排除；
D使用的不定式一般表示出乎意料的结果,且结果状语不可能使用完成形式（完成形式表示发生在谓语动作之前,但是结果是不可能发生在原因之前的）,排除.
