Question

     The question whether there is life on Mars (火星) has made the public think a lot for more than a century. The closest look showed Mars to be a dusty,cold world,covered by air that is too thin to breathe. A British spaceship and Europe's Mars spaceship plan to land on Mars or enter orbit (軌道) around it. One of the NASA’s (美國宇航局) spaceships is expected (期 望) to land on January 3; the other is going to land on the opposite side of Mars on January 24.

    Since 1960,over twenty spaceships sent to Mars have failed. Most have been lost on flying up or landing because those are the most difficult times of any flights. Scientists wanted to find out whether there was water in Mars. In October,a team of scientists reported that Mars had been a dry wasteland. But first appeared here on Earth. Scientists at once raise a question： if what they said is true,what happened on Mars? Then what about the earth?

weeks later,a second team reported differently that they had found some marks showed clearly that they were made by the rivers. Such marks told us that Mars was a warmer place billions of years ago—just as life to the passage?

障礙句分析

But weeks later,a second team reported differently that they had found some marks showed clearly that they were made by the rivers.但是，幾個星期以后，第二組科學(xué)家的報告完 全不同，他們在火星上發(fā)現(xiàn)了一些明顯的河流的跡象。

本句是一個比較復(fù)雜的復(fù)合句，第一個that引導(dǎo)了一個 賓語從句，作reported的賓語，第二個that引導(dǎo)了一個定語從 句，修飾marks。
