【答案】

【1】B

【2】C

【3】C

【解析】

试题分析:

【1】气候温暖,树木生长较快,年轮较厚。由图可知,内部和外侧年轮较厚,中间薄,故选B。

【2】M时期树木生产缓慢,反映气候较寒冷。气候寒冷,雪线下降,AB错。由于气温低,海水体积收缩,同时,两极冰川融化少,海平面下降,C对。气候寒冷,蒸发弱,大气中水汽少,降水少,D错。故选C。

【3】地壳水平运动,岩层发生褶皱,形成巨大的褶皱山脉,块状山地是断层形成的,A错。反气旋中心气流下沉,秋高气爽,B错。全球变暖,世界各地干湿状况变化,导致各地经济结构变化,C对。晴朗的夜晚,大气逆辐射弱,气温低,D错。故选C。

When I was a very young children, my father created a regular practice I remember well years late. Every time he arrived home at end of the day ,we’d greet het at the door. He would ask who we was and pretend not to knowing us, Then he and my mother would have had a drink while she prepared dinner and they would talk about his day and hers. While they chat, my father would lift my sister and me up to sit in the top of the fridge. It was both excited and frightening to be up there!

My sister and I thought he was so cool for putting us there.
