6) _____no cause for alarm,the old man went back to his bedroom.
A.there was B.since
C.being D.there being

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。
