【解析】

這是一篇說明文。文章主要介紹了某種癌癥可以通過氣味來檢測，這使得訓(xùn)練嗅癌犬幫助診斷癌癥成為了可能。

【1】

考查時(shí)態(tài)。結(jié)合上文出現(xiàn)“since then”可知，該句應(yīng)使用現(xiàn)在完成時(shí)，主語為“the dog”是單數(shù)第三人稱形式，故填has been。

【2】

考查名詞的數(shù)。分析該句可知“certain ___2___(type) of cancer”為從句的主語，其后謂語為“are”，推出該句主語應(yīng)該為復(fù)數(shù)形式，故填types。

【3】

考查非謂語動(dòng)詞。此處非謂語動(dòng)詞作狀語，make與其邏輯主語“certain ___2___(type) of cancer ”構(gòu)成主謂關(guān)系，故用現(xiàn)在分詞形式。故填making。

【4】

考查副詞。此處使用副詞greatly來修飾其前動(dòng)詞increase。故填greatly。

【5】

考查不定式。結(jié)合短語allow… to do sth譯為“允許……做”可知此處填不定式，同時(shí)，find out與邏輯主語“them”之間構(gòu)成被動(dòng)語態(tài)，故用不定式的被動(dòng)形式，故填to be found。

【6】

考查固定搭配。此處考查according to譯為“根據(jù)”，為固定短語。故填to。

【7】

考查it用法。此處考查it takes sb time to do sth譯為“花費(fèi)某人多長時(shí)間去做某事”，該句中不定式為真正的主語，而it為形式主語。故填it。

【8】

考查名詞。此處應(yīng)填名詞作tell的賓語，故將different(adj)變成其名詞形式difference，結(jié)合語境，此處可以特指一個(gè)或多個(gè)不同。故填difference\differences。

【9】

考查定語從句。分析該句為定語從句，其先行詞為anyone，在從句中做主語，故用關(guān)系代詞who來引導(dǎo)。故填who。

【10】

考查不定冠詞。句意：任何知道早期癌癥檢測有多么困難的人都知道這是一個(gè)多么好的機(jī)會(huì)。該句為what引導(dǎo)的感嘆句結(jié)構(gòu)：what+不定冠詞+形容詞+單數(shù)名詞+主+謂，本句中不定冠詞后為good opportunity，故使用不定冠詞“a”，故填a。
