When Louise Brown was born on 25 July 1978, she kicked off an era. The first "test tube baby" is a mother herself now, and she’s been joined by millions of others born with the【C1】______of in vitro fertilization(体外受精), or IVF. Now specialists wonder whether people who were conceived by IVF are likely to be【C2】______.
"By and large, the kids are just fine. It’s not like the kids having【C3】______arms or heads," says Carmen Sapienza, a scientist at Temple University. But none is older than their early 30s, and the vast【C4】______are under the age of 20, so they haven’t had time for long-term health problems to show up.
One source of worry is that so many IVF babies have low birth weight. Children-conceived through IVF are more likely to【C5】______less than 2.5 kilograms than are babies conceived【C6】______. That could spell trouble ahead, because low-birth-weight babies often have long-term health problems. They’re more likely to be obese, to have diabetes(糖尿病)or other problems.
With that in mind, Sapienza and colleagues have looked at genes that are likely to play a role in such health problems. They found that certain DNA-patterns, which affect how genes are【C7】______, are different between IVF and non-IVF children. There’s no way to tell if that’s because of the【C8】______used to produce the IVF babies or whether the difference has something to do with the underlying infertility problem the parents had. It’s also【C9】______whether these gene-expression differences will translate into health differences. But it does suggest that children conceived by IVF are【C10】______on some level.
A)weigh E)unclear I)unique M)majority
B)technology F)naturally J)healthy N)minority
C)help G)expressed K)explained O)completely
D)unsure H)procedure L)extra [br] 【C3】
选项
答案
L
解析
此处应为形容词,修饰arms or heads。由上文just fine"还好"可知此处是说手臂或者头是正常的。由空前的not like可知此处应为贬义,填入extra表示“多手臂或多头的小孩”,符合语义。
