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(yīng)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(yīng)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(guān)系，故應(yīng)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。
