Question

_____on the grass _____singing and laughing.

A．Seated ; is some students	B．Seated ; are some students
C．Sitting ; is some students	D．Sitting ; some students are

Answer 1

B

試題分析：句意：坐在草地上，這些學(xué)生又是唱又是笑。這是倒裝句，主語是some students所以謂語動(dòng)詞用復(fù)數(shù)，正常的語序是sb be seated on the grass singing and laughing.故選B。
點(diǎn)評：本題難度適中。倒裝及主謂一致是高中階段的重要的兩項(xiàng)語法項(xiàng)目，它們的各種情況比較多，需要考生牢記它們的用法，但是把兩者結(jié)合一起來考查更增加了試題的難度。
即學(xué)即練：At the meeting place of the Yangtze River and the Jialing River ______，one of the ten largest cities in China.
A．lies Chongqing　　　　　 B．Chongqing lies
C．does lie Chongqing      D．does Chongqing lie
解析：A。表示方位的介詞短語at the meeting place of the Yangtze River and the Jialing River位于句首，故此處應(yīng)該用全部倒裝。
