1、The wise old King praised the boy with his pot empty because the boy did not want to cheat him by showing him some flowers cultivated by others.

2、You can arrive in Beijing earlier for the meeting unless you don’t mind taking the night train.

3、If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe.

【答案】

1、【解析】该题考点为with+宾语+形容词作定语的用法。

    【句意】英明的老国王表扬了拿着空罐子的男孩,因为男孩没有用别人种出来的花来欺骗他。

2、【解析】应该将unless改为provided。该题考察引导条件状语从句的连词。此处provided可以当if理解和使用,用unless不合题意。

3、【妙译】如果能够证明生命独立地存在于火星和地球上,这一结果会对所有科学的最深层奥妙,即宇宙中生命是普遍存在的提供最早的具体线索。

【点拨】本句为复合句,在由if引导的条件状语从句中it作形式主语,that引导主语从句;主句中冒号后面是说明成分,用来说明mysteries。
