答案:a
句型
v.-ing形式作時間狀語
講:請觀察下面教材原句:
passing through the desert,we came out into the salt lake valley,which looked beautiful to us.
穿過沙漠之后，我們來到鹽湖谷，這個地方看起來很美麗。
it is only the first step that is difficult.凡事開頭難。
passing through the desert在這里為v.-ing形式作時間狀語，相當于時間狀語從句after we passed through the desert,...。
例:hearing the news,they all jumped with joy.
聽到這個消息，他們都欣喜若狂。
having finished the work,they had a short rest.
完成那項工作后，他們休息了一會。
having been told many times,he still couldn’t understand it.
被告知了多次之后，他還是不明白。
鏈接•提示
使用該結(jié)構(gòu)時，注意其邏輯主語應(yīng)該是和句子的主語一致，否則就要用狀語從句形式。v.-ing形式作狀語一般表示主動，而被動式使用過去分詞，這時使用狀語從句時就應(yīng)該使用被動語態(tài)。

—why didn’t you go to see the play?
—_________the whole story,i decided not to see it.
a.being told b.i had been told
c.having told d.having been told
提示:從該動詞和主句謂語之間的邏輯關(guān)系分析，此處的非謂語動詞作狀語，與謂語動作有先后之分，故用完成式。
答案:d
鏈接•提示
在使用這一句型結(jié)構(gòu)的簡單句式時，要注意根據(jù)動詞不定式和謂語動詞之間的時間關(guān)系，選擇動詞不定式的正確形式——一般式、進行式、完成式、主動式或被動式。

a.to have sent b.to send
c.to have been sent d.to be sent
提示:由already可知動作已經(jīng)發(fā)生，sb.is said to...=it is said that sb. ..，表示“據(jù)說某人干某事”。
