分析 研究人員決定要找出禽流感是如何在世界范圍內(nèi)進(jìn)行人與人之間傳播的．

解答 答案：B．
turn out結(jié)果是，證明是，figure out找出，算出；pick out挑選出；check out檢驗(yàn)，校驗(yàn)，結(jié)賬．根據(jù)句意"要找出禽流感是如何在世界范圍內(nèi)進(jìn)行人與人之間傳播的"可知，只有figure out與此相吻合；故選B．

點(diǎn)評(píng) 動(dòng)詞短語(yǔ)的意思要弄明白，并結(jié)合句意和句子之間的邏輯關(guān)系進(jìn)行分析，選出正確答案．

2．1．Why do airplanes take longer to fly west than east？
It can take five hours to go west-east from New York （NY） to London but seven hours to travel east-west from London to NY．The reason for the difference is an atmospheric phenomenon known as the jet（噴射）stream．The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic．The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction．
2．What would happen if the gravity on Earth was suddenly turned off？
Supposing we could magically turn off gravity．Would buildings and other structures（建筑物）float away？What happened would depend on how strongly the things were attached to the Earth．The Earth is moving at quite a speed，moving at over a thousand miles per hour．If you turn something around your head on a string（細(xì)繩），it goes around in a circle until you let go of the string．Then it flies off in a straight line．‘Switching off'gravity would be like letting go of the string．Things not attached to the Earth would fly off in a straight line．People in buildings would suddenly shootupwards at a great speed until they hit the ceiling．Most things outside would fly off into space．

60．What information can we get from the first passage？A
A．It is the jet stream that affects how fast airplanes fly．
B．Planes go slower when they are moving with the wind．
C．It takes more time to fly from NY to London than from London to NY．
D．The jet stream always blows from the east to the west across the Atlantic．
61．The word"shoot"underlined in the 2nd passage probably means"B"．
A．send for                                         
B．move quickly
C．come out                                        
D．grow quickly
62．It can be inferred that without gravityB．
A．buildings and other structures would float away
B．trees and buildings would not so easily fly off
C．something around your head would not float away
D．everything outside buildings would fly off into space
63．Where can we most probably read this text？D
A．In a research paper．
B．In a short story．
C．In a travel magazine．
D．In a student's book．
