Is ________48 hours________ the man- made satellite ________ is made in our country to orbit the planet around?
A．it; that; where
B．it; when; what
C．it for; that it takes; that
D．it; that it takes; which
答案
答案：D
题目分析：考查强调句型。本题中的定语从句which is made in our country修饰先行词the man- made satellite。第一空和第二空的强调句型。句意：那颗我国生产的人造地球卫星要花48小时才可以绕地球飞行一周。故D正确。
点评：强调句型的最大特点是把it is/was…that/who去掉句子仍然是成立的。
