会的分析分析
我要这样的分析
It' s reported that by the end of last month the sale of the company ______ by 10%.
A.has risen B.had been rising C.had risen D.has been rising
选C.根据句中的by the end of last month ，证明rise上涨这一动作持续到上个月末，既然截止到过去时间为止，就应用过去完成时，排除A,D。
rise不及物，所以无被动,排除B。

1.Fred entered without knocking and, very out of breath, sank _____ a chair.
A.on B.off C.into D.to 选C.既然连门都没敲就进来，又是上气不接下气，肯定累极了坐在椅子上。off从...脱离 to表方向 人坐在椅子上用in不能用on,（据说因为椅子有扶手，人有包在里面的意味吧）。

2.All the neighbors admire this family, ___ the parents are treating their child like a friend.
A.why B.where C.which D.that
选B.因为名词family后跟的是它的定语从句，根据上下文得知“在这种家庭中，父母像朋友一样对待孩子。”所以排除why表原因，先行词为reason。which，that先行词是物,并在从句中担任主宾语，而从句the parents\their child 是主、宾语。所以只能用where.
3.Do you have a minute? I've got something to tell you.
OK,______ you make it short.
A.now that 既然 B.if only要是...多好 C.as long as只要 D.every time 每次、每当
“你有时间吗？我有些事要和你说。好的，只要你简短说就行。”所以选C正确。

4._______ in the fields on a March afternoon, he couldc feel the warmth of spring.
A.To walk B.walking
to do 开头多用作表示目的“为了”而这个句子是he couldc feel the warmth of spring. 这一动作的伴随动作，所以选B正确。


5.It is generally considered unwise to give a chile _____ he or she wants.
A.however B.whatever C.whichever D.whenever
选B正确。give sb sth这题因为give a child “想要的东西”所以这部分是宾语从句，名词性从句中缺少主语宾语表语时从句用what 引导。所以用whatever.“大家一致认为孩子要什么给什么是不明智的。”
你补充的那道题选A.“手里拿着旅游指南走在大街上。”其它介词意思不搭配。
