题目

—What are you good at, Jeremy?—________. ________ I want to take part in the basketball game this year.A.Playing all kinds of balls; That's because B.Play all kinds of balls; That's whyC.Playing all kinds of balls; That's why D.Play all kinds of balls; That's because 答案：【答案】C【解析】句意：——你擅长什么，杰里米？ ——打各种各样的球。这就是我今年想参加篮球比赛的原因。分析句子结构可知，第一个空的答语应该是I’m good at playing all kinds of balls. 的省略句。因此排除B/D；其次“Playing all kinds of balls.”又是“I want to take part in the basketball game this year.”的原因，小明将1kg温度为10℃的水加热到90℃时，需要吸收　 　J的热量，这相当于完全燃烧　 　m3的天然气放出的热量．．[c水=4.2×103J/（kg?℃），天然气的热值为8×107J/m3]．
