C.土壤
D.气候

【答案】
（1）C
（2）D
【解析】（1）新疆是我国长绒棉的主要产区，该省区深居内陆，远离海洋，降水稀少，不适宜发展水产，适宜发展畜产，故A错误；黄淮海平原适宜种植小麦、花生、花生，甘蔗主要分布在我国的南方地区，故B错误；长江流域适宜种植水稻和油菜，故C正确；华南地区是我国热带经济作物的主要产地，故D错误。故选：C（2）我国南方和北方耕作制度和种植的农作物有明显差异，北方平原广阔，耕地多，但热量较低，降水较少，以旱地为主，主要农作物是小麦；南方多丘陵、山地，但热量高，降水丰沛，以水田为主，主要农作物是水稻。西北地区气候干旱，主要是绿州农业。可见，影响农业最主要的因素是气候条件的显著差异。故选：D

【题目】

The rockets take astronauts and man-made satellites into space. The satellites are used for communication, weather monitoring and research. But how do satellites stay up without Falling down?

There are two opposite forces acting on the satellite. One of them is the force of gravitation(地心引力), which tries to pull the satellite toward the earth. The other force is created by the rotation (旋转)of the satellite around the earth. This force tries to take the satellite away from the earth. With these two forces, the satellite goes round and round. The gravitational pull of the earth is like a rope which keeps the satellite from flying away.

Everything that goes up has to come down. It is only a matter of time before a satellite comes back to the earth. As time goes by, the satellite loses its speed, which makes the gravitational pull stronger than the force pulling it away. This makes the satellite crash (坠落)down to the earth.

【1】The force that pulls the satellite towards the earth is created by ________.

A. the earthB. the satellite itself

C. the rotation of the satelliteD. the rope

【2】Why can't the satellites fly away?

A. Because of the force from the earth.

B. Because the satellite is too big.

C. Because of the force created by the rotation of the satellite around the earth.

D. Because people on earth have made ropes to tie the satellites tightly.

【3】Which of the following is TRUE according to the passage?

A. There are four forces acting on the satellite.

B. The force of gravitation makes the satellite go round and round.

C. As time goes by, the satellite will finally fall down.

D. The satellite will stay in space forever.
