　　參考答案&解析：

　　1、D. certain.

　　[注釋]I am sure that +從句。He is sure to come. = He is certain to come.但在it作形式主語, that引導(dǎo)主語從句時(shí), 主句中表語只能用certain, 不能用sure.

　　2、A. opportunities.

　　[注釋]opportunity常指“ (難得的應(yīng)抓住的) 機(jī)會”, 既可作可數(shù)名詞, 也可以作不可數(shù)名詞用, 如：I had few opportunities of meeting interesting people there. They had not much opportunity for hearing good music in the remote area.

　　3、B. risk.

　　[注釋]run a risk (in) 冒險(xiǎn)：You are running a big risk in trusting him.

　　本題譯文：俱樂部成員不愿冒險(xiǎn)把這個(gè)組織委托給一個(gè)不可靠的人管理。

　　4、C. cut short.

　　[注釋]cut short (=interrupt) 打斷, 中斷

　　5、A. scope.

　　[注釋]本題中scope (=opportunity; outlet) 施展機(jī)會, 發(fā)展余地, 是不可數(shù)名詞, 如：Give someone scope to show his ability. Range意指“變動(dòng)范圍; 視聽范圍; 理解范圍”, 如：the range of prices (價(jià)格變動(dòng)范圍).
