重點(diǎn)詞匯： prudent，take out

■答案■

1、長難句： 這是一個(gè)危險(xiǎn)的游戲：等有了百分之百的證據(jù)，也許就太晚了。隨著風(fēng)險(xiǎn)越來越明顯并且越來越大，一個(gè)謹(jǐn)慎的民族現(xiàn)在應(yīng)該準(zhǔn)備一份保單了。

分析： by the 100 percent of the evidence is in實(shí)際上的意思是by the time when the 100 percent of the evidence is in，即by the time when we have the 100 percent of the evidence。

2、 prudent與careful同義，反義詞是imprudent。it’s prudent to take a thick coat in cold weather when you go out.（天氣這么冷，還是謹(jǐn)慎一點(diǎn)，出門帶上件厚外套。） take out本意是“取出；弄走；消滅”。i’m going to take out my money deposited in the bank.（我打算取出存在銀行的錢。）它還可以表示“發(fā)泄；消滅”。 don’t take your frustration out in such an aggressive manner.（不要用這樣一種攻擊性的方式來發(fā)泄你的失意。）the combat pilots were ordered to take out the enemy position on the hill.（戰(zhàn)斗機(jī)飛行員接到命令，要消滅敵人在山上所建的陣地。）
