Answer 1

1.D 现在分词短语作状语，表原因。
2.A 过去分词表被动。C错是因为少了be动词表被动。
3.B avoid from意思是避开，意思不合，故A错。avoid to意思是避免做，后不加被动，D错。此题应用被动形式“避免被打败”，故选B。
4.C “for a change”，意思为为了改变一下，为了换换花样。
5.D 从句形式不用it,B错。逗号后不跟以that引导的从句，C错；这是一个定语从句，择which更优。
6.D “there was no cause for alarm”和“the old man went back to his bedroom”都是完整的句子，若两句融为一句，其间必要加连词，而此题没有连词，故A错。since同理，故B错。若选C，则“beingn o cause for alarm”的主语为“the old man”，显然不合逻辑。故C错。

Answer 2

1，D伴随状语。2，A被动。3，avoid doing …B项不加from。4，C表目的。5，which非限定性定语从句。6，A过去时，B须加there was表原因

Answer 3

1. D 句意为“他没能成为主席，（因为）没得到大家足够的支持。”前后两个分句并列，使用了分词形式。
2. A 句意为“这可能会使这头大象免于像猎取非洲其他动物那样遭灭绝。”animals是被hunted，所以选择了被动形式。
3. B avoid doing sth.，此处因为是被beatin所以选择被动形式。
4. C for表示目的。
5. D 此处为非限制性定语从句，逗号后接关系代词，表示后半句与前半句关联不大，但也是由前半句陈述事实所引起的。句意为“我们已经按好了中央取暖设备，这样明年冬天这屋子里会大不同的。”
6. D 这是独立主格结构。there be句型用在此结构中，因为是主动形式，所以采用了动词ing形式。

希望对你有帮助！
