　　參考答案

　　1.正確答案：B答案解析：in trouble：陷入困境。由于經(jīng)濟陷入困境，所以支持率下降了很多，符合句意。

　　2.正確答案：C答案解析：本句中that引導的也是同位語從句。

　　3.正確答案：B答案解析：in that意思是：在于，因為。解釋differ from automatic machines的具體方面。

　　4.正確答案：B答案解析：空格前面是belief，后面是一個結構完整的句子，解釋說明belief的具體內容。所以用that引導這個同位語從句。

　　5.正確答案：A答案解析：此題考查的是固定詞組搭配。at a stretch一口氣地。

　　6.正確答案：D答案解析：be left……：被置于……的境地。它是leave sth……的被動式。standing：站立的，固定的，直立的。be left加形容詞是常用的一種表達方式。

　　7.正確答案：C答案解析：譯文：盡管他很累，他也沒有時間休息。此題考查的是讓步狀語從句，從句中表語提前。

　　8.正確答案：D答案解析：譯文：既然我們已經(jīng)有了命題，我們就不應漫無邊際地交談。此題考查對固定短語的掌握情況。at once立刻;at hand在附近，在手頭，即將發(fā)生;at intervals間或，不時;at random隨便，任意。

　　9.正確答案：C答案解析：譯文：當他真正需要鼓勵時，你為什么責備他的拙劣判斷。此題考查準確判斷句子結構。when引導時間狀語從句，what he really needs充當這個時間狀語從句的主語。

　　10.正確答案：B答案解析：本題考查的是短語區(qū)分。A.不休息地，連續(xù)地;B.不知所措，茫然，不了解;C.任意的，隨便的;D.最后，終于。句意：醫(yī)生們不了解執(zhí)行安樂死的準則。
