答案
1. 【答案】B。解析：考查主谓一致。句意：那位老太太带着她的两个孙子一道正在通过马路。 woman是单数，后面动词用单数第三人称形式，together with，就远原则，谓语形式与前面的主语保持一致，故选择B。
2.【答案】D。解析：考查主谓一致。句意：尽管数学很难，但是我们都很努力学。以-ics结尾的学科名词，如politics, physics, mathematics等作主语时，谓语动词用单数;由题意可知应用一般现在时，故正确答案为D项。
3.【答案】C。解析：考查主谓一致和动词语态。句意：练习一应该在课堂上当作例题来做，然而其他的要当家庭作业完成。由语境可知，the rest指代exercise，exercise 作“练习”讲时，为可数名词，也就是说 the rest 指代的是可数名词，谓语动词用复数，A、D错误;exercise 与 finish 之间为动宾关系，故应选C。
4.【答案】B。解析：考查主谓一致。as well as 连接的并列主语采用就前一致原则，some modern teaching equipment为不可数名词，故与第三人称单数形式连用，故B项正确。
5.【答案】A。解析：考查主谓一致。information 是一个不可数名词，所以none of the information 作主语时，谓语要用单数;useful 是形容词，所以A项符合题意。
