1．【答案】D

【解析】根据句子结构我们可以看出，该处应使用分词短语，表示原因，因此A项和B项应予以排除。又因为free和balloon具有逻辑上的动宾关系，所以C项也可以排除。此处使用过去分词表示动作的被动和完成，例如：Influenced by his example，they performed countless good deeds．在他的事迹的影响下，他们做了无数的好事。

2．【答案】A

【解析】before，from和since与quite recently连用不符合语法；before quite recently一般要与过去完成时连用；from (since) quite recently一般要与现在完成进行时连用。until用在否定句中表示”直到……才”之意，例如：It was not until the beginning of the century that man began to realize that it was the brain not the heart that was the center of mind．直到本世纪初，人们才逐渐认识到，是大脑而不是心脏是思维活动的中心。由此可见，A项是正确答案。

3．【答案】C

【解析】过去分词given有时可以作介词，后跟名词，可作”如果有”讲，相当于”with”，例如：Given much more time，he would have done it much better．如果给他更多的时间，他会做得更好。Given good weather，our ship will reach Bombay Friday．假如天气好，我们的船星期五就会到达孟买。Given the opportunity，he might well have become an outstanding painter．如果有机会，他也能成为一位杰出的画家。

4．【答案】D

【解析】当at no time，by no means，hardly，in no case，in no time，in no way，in vain，neither，never，no sooner，nor，not once，not only，not until，on no account，rarely，seldom，under no condition，under no circumstances等具有否定意义的词或短语或从句位于句首且作状语时，主谓要部分倒装，例如：Not only does she sing like an angel，but also dances divinely．她不但歌唱得像天使一样，而且舞跳得也跟天仙一般。由此可见D项为正确答案。

5．【答案】B

【解析】过去分词短语作状语一般要和句子的主语有逻辑上的动宾关系，但是，有时句子中的过去分词虽然和句子主语不是逻辑上的动宾关系，但却符合语法，因为这些过去分词功能相当于一个连词或介词，given就是其中之一。given可用作介词，意为”考虑到，假定，假如”，例如：Given the weather，the football game was quite good．考虑到天气因素，这场足球赛踢得相当不错。Given that he was still a boy，I forgave him．考虑到他还是个孩子，我就原谅他了。
