I think life on Mars is amazing and full of challenges. Scientists find the Mars haven’t been polluted so far. The air is fresh and the water is clean. We can’t see so many cars on Mars, so it isn’t crowded. We can enjoy better life there than on the Earth. But we might get ill while living Mars because of the new living conditions.

And because of the gravity, we can’t play football on Mars. It is also difficult to breath on Mars because it has thinner air than that on the Earth. I think things on Mars will become better in the future.

2.feel like意为“感觉像,有……感觉;愿意(做)……”。like是介词,后面跟名词、代词或动名词作宾语。如:
I feel like a bird in the sky.我感觉自己就像空中的一只鸟。
Yesterday I was sick. I didn’t feel like eating anything. 昨天我生病了,我不想吃任何东西。
用所给单词的适当形式填空。
1.Every time when he is late, the teacher always makes him stand (stand) at the corner of the classroom.
2.This summer I feel like going (go) to the mountains for a trip.
