Answer 1

答案：1．A;2．C;3．A;4．D;5．B;
解析：

(1)	第二段“If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year．”一句即是答案所在。
(2)	文章第一段“Do you know they can tell us what the weather was like…”和第三段的首句“Tree rings are important not only for studying the history of weather…”都有所暗示。
(3)	答案在第二段第三句“…to find out the weather of ten years ago, count the rings of a tree from the outside to the inside．If the tenth ring is far from the eleventh ring…”一句中。
(4)	短文最后一段說，人們建房做飯都離不開樹木，人所居住的周圍環(huán)境中如果沒有了樹木，那么人也就遷移了。所以答案為D項。
(5)	根據(jù)最后兩段所敘述的內(nèi)容，再聯(lián)系植物對人類的重要作用，則不難得出答案。
