【題目】讀“中國農產品主要產區建設規劃示意圖”。
（1）下列農產品主要產區與產品的連線，正確的是（ ）
A.新疆——畜產、水產
B.黃淮海平原——玉米、甘蔗
C.長江流域——水稻、油菜
D.華南——大豆、棉花
（2）圖中我國各產區耕作制度和種植品種差別很大，其主要影響因素是（ ）
A.耕作習慣
B.地形
C.土壤
D.氣候
【答案】
（1）C
（2）D
【解析】（1）新疆是我國長絨棉的主要產區，該省區深居內陸，遠離海洋，降水稀少，不適宜發展水產，適宜發展畜產，故A錯誤；黃淮海平原適宜種植小麥、花生、花生，甘蔗主要分布在我國的南方地區，故B錯誤；長江流域適宜種植水稻和油菜，故C正確；華南地區是我國熱帶經濟作物的主要產地，故D錯誤。故選：C（2）我國南方和北方耕作制度和種植的農作物有明顯差異，北方平原廣闊，耕地多，但熱量較低，降水較少，以旱地為主，主要農作物是小麥；南方多丘陵、山地，但熱量高，降水豐沛，以水田為主，主要農作物是水稻。西北地區氣候干旱，主要是綠州農業。可見，影響農業最主要的因素是氣候條件的顯著差異。故選：D

【題目】
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 (旋轉)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 (墜落)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.
