　　六级选词填空强化练习题原文

　　Once they decided to have children, MiShel and Carl Meissner tackled the next big issue:Should they try to have a girl? It was no small matter. MiShel’s brother had become blind froma hereditary (遗传的)condition in his early 20s, and the Meissners had learned that thecondition is a _1_ passed from mothers to sons. If they had a boy, he would have a 50 per centchance of having the condition. A girl would be _2_.

　　The British couple's _3_ about gender selection led them to Virginia, US where a new sperm (精子)-separation technique, called MicroSort, was under _4_ . When MiShel became pregnant,she gave birth to a daughter. They will try to have a second daughter using the technique laterthis year.

　　This is not only a _5_ effective way to select a child’s gender. It also brings a host of ethical(伦理的)and practical considerations—especially for the majority of families who use thetechnique for _6_ reasons.

　　The clinic offers sex selection for two purposes: to help couples _7_ passing on a gender-linked_8_ disease and to allow those who already have a child to “balance” their family by having ababy of the opposite sex.

　　The technology is still _9_. However, Blauer says the company has an _10_ success rate: 91 percent of the women who become pregnant after sorting for a girl are successful, while 76 percent who sort for a boy and get pregnant are successful.

　　六级选词填空强化练习题答案解析

　　1. [I]此处应为单数名词。根据该句中的blind—词可以知道句中提到的condition其实是一种“疾病”或“不正常”的情况”,disorder为本题答案。

　　2.[D]此处应为名词、动词的分词形式或形容词,在句中作表语。根据该段对这种遗传病的描述可以知道生女孩可以避免遗传到这种病，因此，空格处的单词应该表示“没亊”、“不受影响”等意思，因此本题答案为unaffected。

　　3.[G]空格前的所有格couple’s表明此处需填入名词，作句子主语。inquiries与about搭配，表示“咨询…”,符合此处语义,表明这对英国夫妻咨询与性别相关的事。

　　4.[F]此处应为名词，可与under搭配，表明精子分离技术的现状。在词库的名词中,investigation最适合文中语境，under investigation表明这种技术正处于发展研究当中。

　　5.[L]此处应为副词，形容这种新技术有效使用的程度或范围。根据上文描述的个案，可以知道这种技术“看起来”很有用，词库的副词中seemingly符合句意，因此为本题答案。

　　6.[N]此处应填人reasons的修饰成分，可为名词、形容词或动词分词。从破折号前的ethical and practicalconsiderations可以知道空格处提到的原因可能有悖伦理标准，即并非因为医学上的需要而使用这种技术，由此可见，nonmedical“非医学的”是答案。

　　7.[O]此处应填人动词原形，构成短语help sb. do sth.。空格后的passing on a... disease(把……疾病往下传)表明这种情况是要“避免”或“杜绝”的，故avoid符合语义要求。

　　8.[A]此处应填人修饰disease的词，可为名词、形容词或动词分词。从本文首段提到的个案和本句提到的genderlinked可以推断空格处的单词应表明“遗传性”疾病，因此genetic为本题答案。

　　9.[K]此处应为名词、形容词或动词分词，作句子表语。从本句中的still和下句However引出的内容可以知道，这种技术虽然成功率很髙，但研究仍没有定论，因此本题答案应为experimental，表明技术仍处于“试验阶 段”。本文提到的技术与医学有关，所以不选nonmedical“非医学的”。

　　10.[C]空格处应为success rate的修饰语，可为名词、形容词或动词分词，an表明该词以元音开头。根据冒号后的数据91%和76%,可知成功率很高，故填入impressive“给人印象深刻的，令人赞叹的”。
