summer holidays.

　　A．not permit B．do not permit

　　C．mustn't permit D．couldn't permit

　　解析：选A　recommend在此意为"建议"，其后的宾语从句用虚拟语气，谓语用"should＋动词原形"，其中should可以省略。

　　6．He found a ________ foothold (踏脚处) on the wall and pulled himself up.

　　A．sharp B．weak

　　C．soft D．secure

　　解析：选D　句意：他在墙上找到了一个牢固的踏脚处，然后爬上去。由下文中"pulled himself up"可知，他找到了一个牢固的(secure)踏脚处。sharp"尖锐的，锋利的"；weak"弱的"；soft"软的"；secure"牢固的，安全的"。

　　7．(上海高考) He got well­prepared for the job interview, for he couldn't risk ________ the good opportunity (机会)．

　　A．to lose B．losing

　　C．to be lost D．being lost

　　解析：选B　句意：他为这次工作面试准备得很充分，因为他不能冒失去这次好机会的风险。risk用作动词后跟动词作宾语时，要用动词­ing形式；he与lose之间是主动关系，故选B项。

　　8．More than two hundred people died or were ________ in the earthquake.

　　A．ruined B．injured

　　C．damaged D．destroyed

　　解析：选B　句意：两百多人在地震中死亡或受伤。ruin"毁坏，毁灭"；injure"损害，伤害"；damage"损害，损毁"；destroy"毁坏，毁掉"。这四个单词中只有injure可以指人的生命或肉体受到伤害。

　　9．-Put these glasses away before they ________.

　　-OK. I'll put them in the cupboard.

　　A．have broken B．are breaking

　　C．get broken D．will be broken

　　解析：选C　句意："趁这些玻璃杯还没有被打破，把它们收拾起来吧。""好的。我将把它们放在橱子里。"get broken意思是"被打碎"。空格前的they指代玻璃杯，它与break之间是被动关系，所以排除A、B两项；主句是祈使句时，before引导的时间状语从句应用一般现在时表将来，所以排除D项。故选C项。
