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 from a hereditary(遗传的)condition in his early 20s, and the Meissners had learned that the condition is a【C1】______passed from mothers to sons. If they had a boy, he would have a 50 per cent chance of having the condition. A girl would be【C2】______
The British couple’s【C3】______about gender selection led them to Virginia, US where a new sperm(精子)-separation technique, called MicroSort, was under【C4】______When MiShel became pregnant, she gave birth to a daughter. They will try to have a second daughter using the technique later this year.
This is not only a【C5】______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 the technique for【C6】______reasons.
The clinic offers sex selection for two purposes: to help couples【C7】______passing on a gender-linked【C8】______disease and to allow those who already have a child to "balance" their family by having a baby of the opposite sex.
The technology is still【C9】______However, Blauer says the company has an【C10】______success rate: 91 per cent of the women who become pregnant after sorting for a girl are successful, while 76 per cent who sort for a boy and get pregnant are successful.
A)genetic B)overlapped C)impressive D)unaffected
E)perpetually F)investigation G)inquiries H)feats
I)disorder J)gropes K)experimental L)seemingly
M)elicit N)nonmedical O)avoid [br] 【C9】
选项
答案
K
解析
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高,但研究仍没有定论,因此本题容案应为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”。
