　　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(gè)孫子一道正在通過(guò)馬路。 woman是單數(shù)，后面動(dòng)詞用單數(shù)第三人稱形式，together with，就遠(yuǎn)原則，謂語(yǔ)形式與前面的主語(yǔ)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(xué)很難，但是我們都很努力學(xué)。以-ics結(jié)尾的學(xué)科名詞，如politics, physics, mathematics等作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞用單數(shù);由題意可知應(yīng)用一般現(xiàn)在時(shí)，故正確答案為D項(xiàng)。

　　3.【答案】C。解析：考查主謂一致和動(dòng)詞語(yǔ)態(tài)。句意：練習(xí)一應(yīng)該在課堂上當(dāng)作例題來(lái)做，然而其他的要當(dāng)家庭作業(yè)完成。由語(yǔ)境可知，the rest指代exercise，exercise 作“練習(xí)”講時(shí)，為可數(shù)名詞，也就是說(shuō) the rest 指代的是可數(shù)名詞，謂語(yǔ)動(dòng)詞用復(fù)數(shù)，A、D錯(cuò)誤;exercise 與 finish 之間為動(dòng)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(yǔ)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(xiàng)正確。

　　5.【答案】A。解析：考查主謂一致。information 是一個(gè)不可數(shù)名詞，所以none of the information 作主語(yǔ)時(shí)，謂語(yǔ)要用單數(shù);useful 是形容詞，所以A項(xiàng)符合題意。
