　　Information from the pioneer spacecraft of the National Aeronautics and Space Administration (NASA)obviously proves the theory that the burning 900degree Fahrenheit surface temperature of Venus is due to an atmospheric green- house effect caused mainly by a blanket of carbon dioxide. Such a greenhouse effect is created when energy in the form of sunlight easily passes through a planet's atmosphere (大气) warms is surface and becomes heat radiation that is then held in by the atmosphere. The orbiting spacecraft has collected Venus's atmosphere from top to bottom so that NASA's scientists are able to prove the exact amount (n.总数 总额)of sunlight received at various places in the planet's atmosphere and on its surface. Measurements of atmosphere temperature and radioactive heating foresee Venus' s surface temperature very exactly. The planet is closer to the Sun than it is to the Earth and it has a thin atmosphere like the Earth's but Venus atmosphere is made up of more than ninety percent carbon dioxide(二气化碳) compared to less than four percent in that of the Earth. Because of its higher percentage of carbon dioxide Venus's atmosphere receives much more heat radiation than the Earth's does. Thus the Venus studies are believed to be important to the understanding of possible bad effects on Earth' s agriculture and sea levels that could result from the long term use of fuels which add carbon dioxide to the atmosphere.

[　　]

A．It disappears at the planet's surface.

B．It is received by the atmosphere.

C．It creates energy.

D．It is changed into other kind of energy.

(3)According to the passage how does the atmosphere of Venus differ from that of the Earth?

[　　]

A．It contains much more carbon dioxide.

B．It holds much less water.

C．It is four percent thinner.

D．It receives less heat radiation.

(4)From the passage can be considered that the burning of fuels on the Earth may cause ________.

[　　]

A．more carbon dioxide to enter sea water

B．more sunlight to reach the Earth's surface

C．the atmosphere to become thinner

D．the planet's temperature to change

(5)According to the passage information from the Venus study can be used to ________.

[　　]

A．foresee changes in the planet's orbit

B．foresee future agricultural problems on the Earth

C．test the efficiency of a spacecraft

D．test a theory about more efficient greenhouse
