64、public.D.Houses where statesmen meet regularly.1.C 要猜测stately homes词义，我们只要看看它后面就可以了，它后面有一个and，说明stately homes是与museums并列的一个东西，后面的不定式则说明了这东西的用途，那就是能够展览的地方，我们就选C了。2.Lions are opportunists.They prefer to eat without having to do too much work.When resting in the shade,they are also watching the sky to

65、see what is flying by,and even in the heat of the day they will suddenly start up and run a mile across the plains to find out what is going on.If another animal has made a kill,they will drive it off and take the kill for themselves.A grown lion can easily eat 60 pounds of meat at a single feeding.

67、话“They prefer to eat without having to do too much work.”对它进行了说明，说明狮子想不用干太多的活就可以弄到吃的。这就是个投机主义者。而opportunist的词根opportunity跟D项的chance也是个同义词。所以选D。知识积累Useful wordsillegal(非法的)，hacker(黑客)，security(安全)，site(网站)，retailer(批发商)，password(密码)Useful phrasesbreak down(垮掉)，raise questions(提问题)，get back(取回)，fight
