“I’m certainly more and more to the conclusion that Iraq has, ___they maintained（断言）, destroyed almost all of _____ they had in the summer of 1991.” Bill said.
A．which, what
B．as, which
C．as, that
D．as, what
答案
答案：D
第一空是考查定语从句，先行词是the conclusion，从句___they maintained（断言），意为：正如他们所断言的，要用as，正如，正像；介词of后是宾语从句，且句中缺少had的宾语，要用what。选D.
