Lily: Sand? Like on a beach?
Max: Exactly! He drew a giant chessboard pattern. "Start with one grain," he said. "4. （
Double the amount
） for each of the rest of the squares."
Lily: And the king promised to provide the sand?
Max: Yes, but by square 20, he was worried! 5. （
Even with all the silver
） in his country, he still couldn't buy enough sand.
Lily: So numbers beat real wealth?
Max: Totally! Now I challenge you: At which square would we have enough sand to cover our whole city?
答案：1. for a while
解析：“一會(huì)兒”常用短語“for a while”來表達(dá)，符合語境中 Archimedes 思考片刻的意思。
2. answered without hesitation
解析：“毫不猶豫地答道”，“毫不猶豫地”是“without hesitation”，“答道”是“answered”，結(jié)合上下文用一般過去時(shí)。
3. use sand instead
解析：“用沙子替代”，“用”是“use”，“沙子”是“sand”，“替代”是“instead”，let's 后接動(dòng)詞原形。
4. Double the amount
解析：“數(shù)量翻倍”，“翻倍”是“double”，“數(shù)量”是“the amount”，此處是祈使句，用動(dòng)詞原形開頭。
5. Even with all the silver
解析：“即使用上所有的銀子”，“即使”是“even with”，“所有的銀子”是“all the silver”。

答案：1. wise
解析：根據(jù)首字母“w”及語境，一位“聰明的”老人，“wise”符合。
2. challenged
解析：“challenge sb. to sth.”表示“向某人挑戰(zhàn)某事”，結(jié)合過去時(shí)態(tài)，用“challenged”。
3. promised
解析：國(guó)王“承諾”給獎(jiǎng)勵(lì)，“promised”符合語境及過去時(shí)態(tài)。
4. prize
解析：“any prize”表示“任何獎(jiǎng)勵(lì)”，首字母“p”，“prize”正確。
5. double
解析：前面提到1、2、4，可知是“翻倍”，“double”符合首字母“d”。
6. wondered
解析：國(guó)王“想知道”需要多少米，“wondered”符合過去時(shí)態(tài)及首字母“w”。
7. agreed
解析：但國(guó)王仍然“同意”了，“agreed”符合語境及過去時(shí)態(tài)。
