In China, 60 percent of the current health care fee is paid for by individuals, 25 percent by companies, ______ only 15 percent is funded by the government.
A.what
B.when
C.which
D.while
参考答案:D

考查表示转折的连词while。句意:在中国,目前60%的医疗费用由个人支付,25%由公司支付,而只有15%由政府出资。what意为“什么”,常用来引导名词性从句;when意为“什么时候”,常用来引导状语从句,名词性从句和定语从句;which意为“哪一个”,常用来引导定语从句和名词性从句;while意为“然而”,常用来引导转折句和时间状语从句。故选D。
