At last firemen have put out a big forest fire in California.Since then,they have been trying to find out how the fire began.Forest fires are often caused by broken glass or cigarette ends which people carelessly throw away.Yesterday the firemen examined the ground carefully,but were not able to find any broken glass.They were also quite sure that a cigarette end did not start the fire.This morning,however,a fireman accidentally discovered the cause.He noticed the remains of a snake which was wound round the electric wires of a 16000—volt (伏特) power line.In this way,he was able to solve the mystery (谜).The explanation was simple but very unusual.A bird had snatched up the snake from the ground and then dropped it on to the wires.The snake then wound itself round the wires.When it did so,it sent sparks(火花) down to the ground and these immediately started a fire.
1. Since the big forest fire was put out,the firemen__________.
A.have been busy with the accident
B.have been more and more careful of forest fires
C.have been solving the problems caused by fire
D.have been trying to discover its cause

5.The cause of the fire was considered__________.
A.simple B.ordinary
C.uncommon D.obvious
1、这场森林大火被扑灭后,消防队员一直在努力查找失火的原因。D项中的to discover its cause与文中to find out how the fire began相吻合。既然大火已扑灭了,A项不妥,B项文中没涉及。C项说他们一直在解决大火引起的问题,与文意不符。 2、由文中第五、六句Yesterday the firemen examined the ground carefully,but were not able to find any broken glass.They were also quite sure that a cigarette end did not start the fire.可知。 3、根据文中句子从He noticed the remains of…到句尾可推断出:这场大火是那条蛇引起的。 4、文章一开始提到消防队员一直在查找失火的原因与最后找到了失火原因相吻合。 5、森林火灾常由玻璃片或人们不小心乱扔的烟头引发,而这次火灾是由蛇引起的,因此这次失火的原因不同寻常。

The world’s biggest Internet search engine, Google, has proven once again to be king of the Web. Users can download “Google Wi-Fi” software and then enjoy free Wi-Fi service available in some US cities since last Tuesday.
Wi-Fi is short for “Wireless Fidelity”(无线上网). It allows laptop computers and personal digital assistants to connect to the Internet at high speed by radio sigal.
A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network’s access points. The place covered by one or several access points is called a hotspot. Google had already set up two “hotspots” in the US city of San Francisco which provide a free Wi-Fe service.
The Wi- Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks.
Wi-Fi is stioo limited to a few cities, where there are “ hotspots”. But its capability(容量) of sending information has already done better than that of the mobile phone network, even that of 3G (Third Generation telecommunication technology). Some scientists have started to call Wi-Fi 4G.
In addition to a high speed Internet connection, Fi-Fi has other advantages compared to mobile phones. We-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don’t need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all.
【小题1】 Wi-Fi is not available in cities without_____.
A.a computer | B.a radio | C.a hotspot | D.a cell phone |
A.it is the product of the Google”s 4th generation. |
B.it is more capable of sending information than the mobile phone network. |
C.it has been used by more than four generations. |
D.Wi-Fi will surely take the place of the mobile phone network. |

Free to fly with the wind
One windy spring day, I observed young people having fun by flying their kites in the wind. Colorful creations of varying shapes and sizes filled the blue and clean skies like beautiful birds dancing. As the strong winds blew against the kites, a 16 kept them in control.
Instead of blowing away with the wind, they went up against it to achieve great 17 . They shook and pulled, but the control string and the long tail kept them under 18 , facing upward and against the wind. As the kites struggled and trem??bled against the string, they seemed to be saying, " Let me go t Let me go! I want to be 19 !" They flew beautifully even as they fought the control of the string. Fi??nally, one of the kites 20 in breaking loose. "Free at last," it seemed to be saying, "Free to fly with the wind.”
Yet freedom from control simply put it at the 21 of an unsympathetic wind. It dropped ungracefully to the ground and landed in a wild mass of weeds. “Free at last”--- free to 22 powerlessly in the dirt, and to be blown 23 along the ground……
How we are like kites sometimes! The Heaven gives us adversities(逆境), limits and rules to ????????_ 24 from which we can grow and gain strength. Control is a necessary opponent(对手) to the winds of opposition. We can never go up high enough to achieve our goals sometimes if we lose our necessary 25 or the rules.
16 A belt B string C wire D wind
17 A skies B lengths C depths D heights
18 A charge B repair C condition D control
19 A quicker B higher C free D quiet
20 A ended B stuck C failed D succeeded
21 A mercy B top C bottom D expense
22 A sit B stand C exist D lie
23 A patiently B silently C helplessly D comfortlessly
24 A escape B follow C break D suffer

Jaime, Bradley, Carrie, Josh和Alan每人根据自己的职业作答了一份关于Robot的调查问卷,第71至75题是他们的职业介绍。阅读下面七项信息(A、B、C、D、E、F和G),选出与他们职业匹配的最佳选项,并标在答题纸的相应位置上, 选项中有两项是多余选项。
71. _______ Carrie is a young man who has a job in a city construction company. He is afraid of climbing up ladders and carrying the iron bars and concrete onto higher places.
72. _______ Jaime is a professor in the field of biochemistry. He is worried about his health situation as he keeps so close to harmful elements year in and year out.
73. _______ Bradley works in the International Ocean Security Association. He is sad to think of the fact that there were so many people who couldn’t be saved at last in disasters.
74. _______ Alan is a worker in an auto factory. He is thinking of changing another job which is more interesting and creative.
75. _______ Josh is an administrator of the National Spaceflight Bureau, which is short of qualified pilots at the moment.
A
I suppose robots could be used as dust people during night time, as they don’t need to sleep and they are comparatively safe in polluted environment.
B
I suppose small remote control robots could be used as sea rescuing workers to search through wreckage(打捞)in a disaster looking for people in the sea. Bomb defusers(扫雷管)are now robots reducing the risk of losing a life.
C
I suppose robots could be used to do jobs that are dangerous, as they can lift heavy objects, paint, handle chemicals, and perform the same job hour after hour, day after day without stop.
D
I suppose robots could be used as chemical researchers. At least they can help us carry harmful chemicals in a chemical plant or help to go into small areas inaccessible to us. It can be used to examine the inside of a nuclear reactor(核反应堆).
E
I suppose robots could be astronauts and they could travel very far away, like Pluto. If they can, we don’t need to especially train human beings to be astronauts as it costs quite a lot and it also takes many years to make a professional astronaut.
F
I suppose robots could be used as car assembly(装配)workers, in parts of a car building line. Assembly lines make the process move faster, get more work done and cost less. But the job is so mechanical and boring.
G
I suppose robots can do such dangerous jobs as sky-scraper builders that would be safer for human beings. If injured or broken, they can be fixed easily. They can also work in unfavorable conditions such as dark, extreme heat, extreme cold etc.
