1.Only after the anesthetist(麻醉师）gave the patient an anesthetic(麻药）,______.
A.the operation could be conducted
B.could the operation be conducted
C.the operation could conduct
D.could the operation conduct
答：一、 Only +状语,主句部分倒装.
状语有三类：1.副词,如：Only then did he realize that he was wrong.
2.介短,如：Only in this way can we learn English well.
3.从句,如：Only when the war was over was he able to come back home.
本题选B.
译：只有在麻醉师给病人注射了麻药之后才能动手术.
析：AC没倒装,排除.
operation 是被conduct,用被动语态,排除D
2.Only a selected number of landladies in the neighborhood have been allowed by the university to take in___.
A.residents B.lodgers C.inhabitants D.settlers
ABC选项都是“房客,居民”的意思,怎么区别呢?Only引导句子后面是应该倒装吗,这里怎么没倒?帮忙分析下,谢啦
答：所谓倒装,就是谓语动词的全部或一部分倒过来放在了主语的前面.既然Only 后面加的是作主语的名词或代词放在最前面了,还怎么倒装呢?所以所谓的“Only +主语,句子不倒装,根本就是废话,这种情况下,你想倒装也倒装不起来啊!（主语已经在谓语的前面了!）
这一题选B
译：本小区只有指定的一些（女）房东得到了大学的允许,可以接纳房客（简称接客^_^,这下子明白为什么是landladies了.）
本题考词汇.AC同义 “居民”,D.殖民者、移居者,不合句意.B.寄宿者,只有它合句意.
