Cloning may have _6_ uses besides its ability to help farmers _7_ breed quality burgers andbacon. Other potential uses _8_ the preservation of species, biomedical research, drug andorgan production and even commercial ventures.
It seems that finding out exactly how many cloned animals have been produced is almost asdifficult as producing them in the first place. There’s no official _9_ of clones, and laboratoriesaren't required to report every single tadpole or mouse they create. But armed with a bit ofknowledge concerning animal cloning and its _10_, it’s likely to narrow down the contestants toa possible field.

六級選詞填空模擬練習題答案
1.[D]空格前后分別為句子的主語和謂語,因此空格應為副詞。前一句中的half right表明本句將要說出“真正的”答案,故選actually,說明上文提到的那些名字“事實上”是幾種克隆動物的名字。
2.[H]空格應為形容詞、名詞或分詞,作定語修飾status。上文提到的幾種克隆動物的名字不太為人所熟悉,而這里所講的多利羊(Dolly)很多人知曉(familiar),故此處選用celebrity,表明多利羊“很出名”。
3.[L]空格在定冠詞和名詞之間,為修飾名詞的定語。From…to…結構表明空格最有可能是形容詞,這樣the...guar形式上才能與the common crow—致。該句前面提及很多不同物種被克隆了,其后舉例加以說明, 由此推斷此處應該是從“普遍”到“特殊”的列舉,endangered符合語義。
4.[B]空格位于that引導的從句中,從句的主語是food products,謂語是are safe,可見空格應該是修飾foodproducts的后置定語。from the clones of...表明填人空格的詞應表示某種動向且能與from搭配,最可能是過去分詞。derived符合句意,表明“源自克隆牛、克隆豬和克隆羊的食物可以安全食用”。
5.[F]通過分析句子成分可知,空格是主句的謂語,與an already growing interest構成動賓搭配,其主語是declaration。in early 2008提示謂語動詞為一般過去時。動詞庫中intensified“增強”能與interest;構成動賓搭配,填入空格句意通順。
6.[E]空格在名詞uses之前,作其定語。下一句提到克隆技術可能用于保存物種、生物醫學研究等,可知這一技術除幫農民生產出漢堡包和熏豬肉外,還有其他用途。additional符合句意。
7.[O]空格在動詞詞組help... breed之間,應為副詞。本段講克隆技術的好處,故填入的副詞應包含積極意義,consistently符合語境,表示“源源不斷地”生產出髙質量的漢堡包和熏豬肉。
8.[I]空格處應為動詞,作句子謂語。主語為other potential uses,賓語為克隆技術應用的各領域,詞庫中動詞include “包括”符合此處句意。
9.[M]空格位于no和介詞of之間,應為名詞,且被official修飾。本句解釋難以確切知道有多少克隆動物的原因,此處指出其中一個原因“沒有關于克隆的官方……”,registry符合句意。
10.[C]空格在形容詞性物主代詞its后,應為名詞。本句說的是找到更多克隆動物的方法,那就要具備這方面的相關知識,此處應選用applications,填人文中意為“只要掌握一點關于克隆及其應用的知識,就能縮小找尋被克隆的動物的范圍”。
