这是一个强调句.
有这样一个句型“It takes sb. some time to do sth ”某人花多长时间做某事
另外,强调句型是 It is + 被强调部分+ that + ……
把那个题干变成陈述句应该是这样：
It is (45 hours )that it takes the man-made satellite (made in our country )to orbit the planet around.
其实这句话就是上面两个句型的结合.
其中,(45 hours )是被强调部分
(made in our country )是做satellite 的后置定语.

是强调句。
