当卫星的圆面遮盖住太阳的圆面,其阴影就会投射到地球上.
这个属于天文了,应该是说当卫星和太阳处于同一条直线的时候,卫星遮住了太阳的光球层,卫星就会在地球上投下阴影.不知道说的对不对,问问懂天文的人吧.

The rockets take astronauts and man-made satellites into spa 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 (力量) acting on the satellite. One of them is the force of gravitation (地心引力), which tries to pull the satellite towards 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 (the force which pulls everything towards the ground) 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. 小题1:Which of the following uses of satellites is NOT mentioned? A．communication B．monitoring the weather condition C．doing some research D．taking pictures 小题2:The force that pulls the satellite towards the earth is created by ________. A．the earth B．the satellite itself C．the rotation of the satellite D．the rope 小题3: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. 小题4:The satellite will finally crashes down to the earth ________. A．when it flies faster B．when its speed slows down C．when people cut the rope D．when there is no electricity in it 小题5: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. nakun_j1年前1: 朝雾共回答了13个问题 | 采纳率76.9%

短文属于说明文。介绍了人造卫星不会坠落的原理。
小题1:细节理解题。从第一段第二句“…are used for communication, weather monitoring and research.”可知没提到D项。
小题2:推理判断题。从第二段最后一句“The gravitational pull of the earth”可知地心引力来自于地球。
小题3:综合理解题。从第二段第二句“…tries to pull the satellite towards the earth”和最后一句“…keeps the satellite from flying away”可知：是因为地心引力。
小题4:细节理解题。从短文后两句“…loses its speed…crash down to the earth”可知。
小题5:综合理解题。通读全文，可知A、B、D三项不符合文意；C项与短文最后一段吻合。

Now satellites are helping to forecast（预报）the weather. Now satellites are helping to forecast（预报）the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere（大气）, because this is where the weather forms（形成）. They send these pictures to the weather stations. So meteorologists（气象学家）can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.　　 Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare（比较）them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this. So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead（提前）. 小题1:Satellites travel _____________. A．in space B．in the atmosphere C．above the ground D．above space 小题2:Why do we use the weather satellites to take pictures of the atmosphere? Because __________. A．the weather satellites can do it easily B．clouds form there C．the weather forms there D．the pictures can forecast the weather 小题3:Meteorologists forecast the weather __________. A．when they have received satellite pictures B．after they have compared new satellite pictures with earlier ones C．before they received satellite pictures D．during they study satellite pictures 小题4:Maybe we’ll soon be able to forecast the weather for ________. A．one day B．two days C．five days D．seven days or even longer 小题5:The main（主要的）idea of this passage is that satellites are now used in _________. A．taking pictures of the atmosphere B．receiving pictures of the atmosphere C．doing other work in many ways D．weather forecasting beizishui1年前1: suifengma 共回答了24个问题 | 采纳率87.5%

Assume that the radius of the equator is r.Then by the formula of the circle's circumference,we have the expression
2pi ( r +250) as the circumference of the satellite,and 2 Pi r as the circumference of the equator.Then by taking the difference,we have 2*Pi*r + 500*Pi - 2*Pi*r = 500Pi,which is approximately 1570 miles.

问一个被动语态的问题,The photographs of Mars taken by satellite are mu 问一个被动语态的问题, The photographs of Mars taken by satellite are much clearer than those taken from the earth.大意是卫星拍的火星照片比在地球上拍的火星照片清晰.我的问题是：这是一个一般过去时的被动语态,为什么两个taken前面没有were呢? xOx0071年前3: ssssss 共回答了16个问题 | 采纳率81.3%

一个句子里面只能有一个谓语!如果taken前面加were了,那么这个句子就不止一个谓语了.这个句子的谓语是are,其他两个taken是做photo的后置定语,就是修饰photo的,什么样的photo,卫星拍下来的photo,原句应该是The photographs of Mars (which are )taken by satellite are much clearer than those(which are) taken from the earth,在这里可省略,被动语态就用过去分词,主动就ing形式的,我解释清楚了吗?有点罗嗦

most 是大部分的意思,换成many语法没错,改变了意思,
换成much就不行了,much只能修饰不可数.
可以加travel...
