6． the direct personality of Americans is widely appreciated，it sometimes surprises foreigners．（　　）

A．

Since

B．

C．

When

D．

While

分析雖然美國人的直率個性受到廣泛的贊賞，但它有時也會讓外國人感到驚訝．

解答答案D．since"因為"，引導原因狀語從句；if"如果"，引導條件狀語從句；when"當…時"，引導時間狀語從句；while表示"當…的時候"，引導時間狀語從句；意為"盡管、雖然"，引導讓步狀語從句；意為"而、但是"，引導比較狀語從句．分析可知前后兩句話之間是邏輯上的"讓步"關系，此時可排除A、B、C三項，故答案選D．

點評本題考查從屬連詞的用法．連詞的用法辨析，要注意分析主從句之間的邏輯關系，再確定相應的連詞，同時注意不同的連詞的語義及用法區別．

8．The 2012 London Olympics had enough problems to worry about．But one more has just been added-a communications blackout caused by solar storms．
     After a period of calm within the Sun，scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012，just in time for the arrival of the Olympic torch in London．
     Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth，causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London．
"The Sun's activity has a strong influence on the Earth．The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites，"said Professor Richard Harrison，head of space physics at the Rutherford Appleton Laboratory in Oxfordshire．
     At the peak of the cycle，violent outbursts called coronal mass ejections （日冕物質拋射） occur in the Sun's atmosphere，throwing out great quantities of electrically-charged matter．"A coronal mass ejection can carry a billion tons of solar material into space at over a million    kilometres per hour．Such events can expose astronauts to a deadly amount，can disable satellites，cause power failures on Earth and disturb communications，"Professor Harrison added．The risk is greatest during a solar maximum when there is the greatest number of sunspots．
     Next week in America，NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory （SDO），which will take images of the Sun that are 10 times clearer than the most advanced televisions available．
     The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares （太陽耀斑） and explosions as they occur．
     Professor Richard Hold away，the lab's director，said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth"If we have advance warning，we'll be able to reduce the damage．What you don't want is things switching off for a week with no idea of what's caused the problem，"he said．

72．The phrase"communications blackout"in paragraph 1 most probably refers toB during the 2012 Olympics．
    A．the extinguishing of the Olympic torch
    B．the collapse of broadcasting systems
    C．the transportation breakdown in London
    D．the destruction of weather satellites
73．What can be inferred about the solar activity described in the passage？D
     A．The most fatal matter from the corona falls onto Earth．
     B．The solar storm peak occurs in the middle of each cycle．
     C．It takes several seconds for the charged matter to reach Earth．
     D．The number of sunspots declines after coronal mass ejections．
74．According to the passage，NASA will launch a satellite toC
    A．take images of the solar system    B．provide early warning of thunderstorms
    C．keep track of solar activities     D．improve the communications on Earth
75．Which of the following might be the best title of the passage？D
   A．Solar Storms：An Invisible Killer
   B．Solar Storms：Earth Environment in Danger
   C．Solar Storms：Threatening the Human Race
   D．Solar Storms：Human Activities to Be Troubled．

1．根據短文內容，從下框A～F選項中選出能概括每段主題的最佳選項，并在答題卡上將該選項涂黑．選項中有一項為多余項．
A．A sense of humour is not an inborn ability．
B．A sense of humour can be developed in our life．
C．A sense of humour helps us from several aspects．
D．A sense of humour means more than telling jokes．
E．A sense of humour can be expressed in many ways．
F．A sense of humour helps people to better enjoy life．
61．A sense of humour helps us from several aspects．
As awareness of the cenefits of humour increases，most of us want to get all the langhs we can．It seems that almost every day there is another new discovery about the power of humour to help us physically，mentally，cmotionally，and sp[iritually．Every system of the body responds to langhter in some important or positive way．
62．A sense of humour is not an inborn ability．
Many pcople mistakenly believe that we are born with a sense of humour．They think that when it comes to a sense of humour．"either you have got it or you don't．"This is
false!What is true，however，is that the ability to laugh and smile is actually something we are born with．For example，we laugh when we are tickled under the arm，even without thinking about how to react．
63．A sense of humour can be developed in our life．
The parts of the brain and central nervous system that control laughing and smiling are mature at birth in human infants，but that is not the same thing as having a sense of humour．（After all，when a baby laughs in his small bed we don't rush over and say，"That kid has a great sense of humour!"） Your sense of humour is something you can develop over a lifetime．Don't be nervous before others and try to laugh at yourself-then you will make them laugh too．
64．A sense of humou means more than telling jokes．
Humour includes a lot more than laughing and joke telling．Many people worry needlessly that they do not have a good sense of humour because they are not good joke tellers．More than jokes，a sense of humour requires being willing and able to see the funny side of life's situations as they happen．In fact，one of the best definitions（定義）of a sense of humour is"the ability to see the nonserious element in a situation．"
65．A sense of humour helps people to better enjoy life．
There may be a thousand different ways to express your sense of humour，but joke telling is only one of those ways．As more is discovered about how humour benefits our life，more people will be able to see and enjoy the humour when they are in a difficult situation．Life depends on air，food and water，but it is made easier to live with a good sense of humour．
