參考答案&解析:
1、A 此題考查上下文理解。下文舉例說明的部分提到將一句話的某個詞換成另外的詞,由此推斷可知,此處選擇replace(代替)。
2、C 表達(dá)用另一個詞代替,用another。
3、B 此題考查上下文理解,會說一句話和能夠把這句話里的某個單詞用別的詞替換,這之間表達(dá)的應(yīng)是一種并列關(guān)系。故選B。
4、C 此題考查非限定性定語從句,必須用which。
5、C 動物發(fā)出的聲音不能形容為“標(biāo)記”、“記號”或是“手勢”,因此,只有signal信號才是正確選擇。
6、A 此處考查固定搭配。in point指“適用的,相關(guān)的”
7、A 作者將山雀能發(fā)出20種叫聲與人類語言能發(fā)出更多的聲音相比較,這里應(yīng)該選擇轉(zhuǎn)折連詞:whereas(然而)。
8、C 參照上題,此處將人能發(fā)出的聲音數(shù)量與動物進(jìn)行比較。boundless(無界限的),changeable(多變的),ceaseless(不停歇的),因此,正確選項(xiàng)是C。
9、B
