答案
1. 【答案】B。解析:考查主謂一致。句意:那位老太太帶著她的兩個孫子一道正在通過馬路。 woman是單數(shù),后面動詞用單數(shù)第三人稱形式,together with,就遠原則,謂語形式與前面的主語保持一致,故選擇B。
2.【答案】D。解析:考查主謂一致。句意:盡管數(shù)學很難,但是我們都很努力學。以-ics結(jié)尾的學科名詞,如politics, physics, mathematics等作主語時,謂語動詞用單數(shù);由題意可知應用一般現(xiàn)在時,故正確答案為D項。
3.【答案】C。解析:考查主謂一致和動詞語態(tài)。句意:練習一應該在課堂上當作例題來做,然而其他的要當家庭作業(yè)完成。由語境可知,the rest指代exercise,exercise 作“練習”講時,為可數(shù)名詞,也就是說 the rest 指代的是可數(shù)名詞,謂語動詞用復數(shù),A、D錯誤;exercise 與 finish 之間為動賓關系,故應選C。
4.【答案】B。解析:考查主謂一致。as well as 連接的并列主語采用就前一致原則,some modern teaching equipment為不可數(shù)名詞,故與第三人稱單數(shù)形式連用,故B項正確。
5.【答案】A。解析:考查主謂一致。information 是一個不可數(shù)名詞,所以none of the information 作主語時,謂語要用單數(shù);useful 是形容詞,所以A項符合題意。
