Question

AVERAGE RESOURCES(资源)
620 m3 water	If we put flesh water and sea water together，we can each have 620 m3 water．But remember，sea water is too salty for us to drink if the factories don’t process(加工)it first．So，620 m3 is little．Saving water in daily use is important．
0．5 hectares of forests	There are 3．869 billion hectares(公顷)of forests on Earth．But we are losing them mainly because we cut trees too much．If we calculate(计算)at the size of a football field，we are losing 343，000 football fields every day，or 1，431 per hour，or 24 per minute !
1．5 centimeters long corals(珊瑚)	All the corals that we have now spread(绵延)for about 100，000 km in 109 countries．But each of us can only have such a little piece，because seas are get-ring polluted and corals are dying．
33 stars	According to the latest report，there are 200 billion stars in the Milky Way．Each of us can have 33 of them．Unfortunately，we cannot see most of the 200 billion stars from Earth．We can only see about 6．000 stars．If we don’t use telescopes(望远镜)or we have bad weather，we can only see about 2，000 stars．
90kg rice	On average(平均)，we get 0．54 billion tons of rice each year round the world and each of us can have 90 kg．Asia produces and eats 90％of all the rice．How long will it take you to eat up this 90 kg rice?

小题1:On average，maybe we each have________fresh water in the world．

A．620m3	B．more than 620m3
C．far less than 620m3	D．no more than 620m3

小题2:When we use telescopes or the weather is fine，we can see________stars from Earth．

A．all the stars

B．about 200 billion

C．about 2．000

D．about 6．000

小题3:According to the table above，we each can only have________because of pollution．

A．less water

B．fewer forests

C．fewer corals

D．less rice

小题4:We are losing___________football fields every day because people cut down too many trees.

A．343，000

B．3．869

C．1，431

D．24

小题5:Which of the following is true according to the passage?

A．We get 0.54 billion tons of rice each year round the world and each of us can have 9 kg．

B．We cannot see most of the 20 billion stars from Earth．

C．Sea water is too salty for us to drink if the factories don’t process it first．

D．each of us can only have some pieces of corals，because seas are get-ring polluted．

Answer 1

小题1:C
小题2:D
小题3:C
小题4:A
小题5:C

小题1:细节理解题，根据文中语句“If we put flesh water and sea water together，we can each have 620 m³ water．”理解可知。只有淡水我们每人的平均量是远远达不到620.
小题2:细节理解题，根据文中语句“Unfortunately，we cannot see most of the 200 billion stars from Earth．We can only see about 6．000 stars．”理解可知。我们只能看到其中的一部分星星。
小题3:细节理解题，根据文中语句“All the corals that we have now spread(绵延)for about 100，000 km in 109 countries．But each of us can only have such a little piece，because seas are get-ring polluted and corals are dying．”理解可知。我们只能有少量的珊瑚
小题4:细节理解题，根据文中语句“If we calculate(计算)at the size of a football field，we are losing 343，000 football fields every day，”理解可知。我们每天要减少343，000 football fields
小题5:细节理解题，根据文中语句“But remember，sea water is too salty for us to drink if the factories don’t process(加工)it first．So，620 m³ is little．”理解可知。
