【B5】
It is natural that a tree would grow best in a climate with plenty of sunlight and rainfall. It is also expected that little sunlight or rainfall would limit the growth of a tree. The change from a favorable to an unfavorable climate can be determined by reading the pattern of rings in a tree trunk (树干). To find out the weather of ten years ago,count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that plenty of sunny and rainy weather occurred. If the rings are close together, then the climate was bad for the tree.
选项
答案close
解析 从前文得知，气候适宜，树木生长得快，年轮间的距离就宽；反之如果气候不适宜，树木长得慢，年轮间的距离自然就会比较近。对照前句中ring is far from可知，后句the rings are后应填close。
