【解析】

試題分析:

【1】我國(guó)的氣候特征之一是季風(fēng)氣候顯著,我國(guó)夏季受夏季風(fēng)的影響,夏季風(fēng)從海洋上吹來,是給我國(guó)帶來降水的主要因素。夏季風(fēng)強(qiáng),降水多,夏季風(fēng)弱,降水少,所以夏季風(fēng)的不穩(wěn)定是造成旱澇災(zāi)害的主要原因。

【2】我國(guó)是自然災(zāi)害頻繁的國(guó)家,江淮地區(qū)主要的災(zāi)害是洪瀨災(zāi)害,黃河下游地區(qū)主要的災(zāi)害是旱災(zāi),西北地區(qū)主要是旱災(zāi),青藏高原主要是地震等災(zāi)害。所以選A。
