Rocket engines have【C1】______powerful enough to shoot astronauts【C2】______the earth’s gravitational pull and【C3】______them on the moon. We have now become【C4】______in space.
Impressive and complex【C5】______it may appear, the rocket, which was【C6】______in China over 800 years【C7】______, is a relatively simple device. Fuel that is【C8】______in the rocket engine changes【C9】______gas. The hot and rapidly【C10】______gas must escape, but it can do so only through an opening that faces backward.

选项
A、shown
B、been
C、appeared
D、proved
答案
D
解析
prove证明。因其后接形容词powerful作表语,故应填系动词。shown不是系动词;been和appeared虽可作系动词但与句意不符;而proved可作系动词,意为“证明是”,符合句意。
