C.
解析：本题由第二段第二句“The Philippine islands owe their existence to the ejections of lava in the past over a period of several million years．”可知，数百万年前的火山喷射的熔浆形成了菲律宾群岛，故答案正确。
3.(T)

C.
解析：本题题意为火山在1991年6月12号开始活动，由第二段第三句“A huge cloud of volcanic ash and gas rose above Mount Pinatubo on June 12，1991．”可知，6月12日，皮纳图博火山产生大量的火山灰和气体，故答案正确。
4.(T)

5.(F)
A. TRUE

B. FALSE
C.
解析：本题由第三段倒数第二句话“Following Mount Pinatubo’s disastrous eruption on June 15，1991，thousands of roofs collapsed under the weight of ash which was made wet by heavy rains．”可知，1991年6月15目的火山爆发之后，成千上万的房屋被火山灰所覆盖，题中是在15日这天，故错误。
7.(T)
A. TRUE
B. FALSE
C.
解析：本题由第四段第一句“Nearly 20 million tons of sulfur dioxide were injected into the upper atmosphere in Pinatubo’s 1991 eruptions．”可知，在火山爆发中，有约两千万吨二氧化硫注入到了上层大气中，与题意一致，故正确。
8.(F)
A. TRUE
B. FALSE
C.
解析：本题意为，火山爆发加剧了全球环境污染，而第四段第二句、第三句“caused global temperatures to drop temporarily by about 1 degree. The eruptions have changed the face of central Luzon dramatically”只是说爆发使得全球气温暂时下降1度及使得Luzon中心地带的地表完全改变，并没有说它对全球环境造成污染，故答案错误。
9.(T)
A. TRUE
B. FALSE
C.
解析：文中倒数第二句“About 2，000，000 people…have returned home but face continuing threats from lahars…”即一些被疏散的人回到了家，但受到火山泥石流的持续威胁，与题句意思是一致的，故答案正确。
