【解析】

文章介紹了克隆的產(chǎn)生與發(fā)展。

【1】考查冠詞。此處表示做另一只動物或植物的復制品，所以用不定冠詞，exact 為元音開頭，所以用an。

【2】考查不定式。此處表示是一項很難進行的任務。此處要用to undertake 做task的定語。

【3】考查固定短語，此處表示有了回報所以用pay off。

【4】考查從句連詞。此處從句是解釋fact的內(nèi)容，為同位語從句，從句句子完整，不缺成分，不缺意義，所以用從屬連詞that 引導。

【5】考查現(xiàn)在分詞。此處修飾news，表示煩人的消息，形容事物用現(xiàn)在分詞。

【6】考查名詞。Of 為介詞，后缺賓語，因此要用名詞作賓語，另外反對不止一個，所以用復數(shù)。

【7】考查副詞。此處作狀語，表示明顯地，它變得有爭議，所以用副詞apparently。

【8】考查非謂語動詞。此句謂語為are，表示克隆研究需要的卵細胞和胚胎，因此需要與卵細胞和胚胎之間是被動關(guān)系，所以用過去分詞。

【9】考查非謂語動詞。此處做of 的賓語，evil leader 與hope 之間是主動關(guān)系，所以用現(xiàn)在分詞。

【10】考查謂語。此處and 連接前后兩個謂語，表示改革法律體系，禁止克隆人的研究，因此與reformed 并列，所以用forbade。
