1.【命题立意】考查句子结构的准确识别。
【答案】A【解析】本题容易误选B,误把being solved当成 paying attention to的宾语。如果把此复合句还原成两个简单句: He suggested the problem 和The problem is worth paying attention to, 很容易看出空白处应填 “(should)+动词原形”,worth paying attention to是修饰宾语从句主语the problem。故答案为A。at the meeting.
2.【命题立意】考查强调句型结构的完整性。
【答案】A【解析】第一空考查主语从句的引导词。主语从句中,achieved缺少宾语,what在主语从句作宾语;第二空为强调句型部分,应用that,被强调部分为what Li Na, a Chinese famous tennis player, has achieved at the French Open。
