	A．	to have received		B．	so as to be receiving

分析所有明信片必须马上寄出，以便春节时能及时收到．

解答答案：C
句意表达的是目的；receive与主语postcards之间构成动宾关系，要用不定式的被动形式来构成目的状语．故选C．

点评动词不定式是非谓语动词是一种，表示未发生的动作，用法较多．常用来作定语，主语，宾语，补语，状语等．本题中用来作目的状语，相当于in order to为了．

8．Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy．Apart from this，studies are being carried out to harness（利用） usable wind energy produced by man-made technologies．
One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train，which produces fierce wind that can be transformed into electricity．
According to Pradhan's proposal，with a few small improvements in existing trains running in Mumbai，the largest city in India，at least 10，000megawatts（兆瓦） of electricity could be harvested each day．
Building on this principle，designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device（装置） called T-Box that harnesses wind energy from speeding trains．
T-Box can be placed within the railway tracks．It is half-buried underground between the concrete sleepers（水泥枕木），which does not disturb the normal train operating at all．According to Yanko，around 150T-Boxes can be fitted along a 1，000-meter railway track．
A train running at a speed of 200kph can produce winds blowing at 15miles a second．Based on this calculation，150T-Boxes can produce 2.6KWH of electricity per day．The T-Box's design won a silver medal in last year's Lite-On Awards and was exhibited last summer at the Xue Xue Institute in Taipei，Taiwan Province．
Though the figures look impressive，it is important to remember that the design is still at a conceptual stage and hasn't taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance（维护） of the device．
We can expect the technology to see the light of the day only after it clears these issues．If so，rail travel，one of the greenest forms of travel，will become greener and more energy-efficient．
46．What can we learn about T-Box？A
A．It is based on Pradhan's idea．
B．It will be fitted on the trains．
C．It can turn electricity into light．
D．It was invented by an Indian scientist．
47．How much electricity can be produced per day by T-Boxes along a railway track of 100km？A
A.260KWH．
B.2.6KWH．
C.150KWH．
D.1.5KWH．
48．It can be concluded from the last two paragraphs thatC．
A．T-Box has proved to be effective in harvesting wind
B．the maintenance of T-Box will be costly
C．there is much to do about T-Box
D．T-Box will come into use soon
49．According to the passage，which of the following statements is TRUE？B
A．The Indian inventor Santosh Pradhan invented the speeding train．
B．The T-Box's design won a silver medal in Lite-On Awards last year．
C．Rail travel has become one of the energy-efficient technologies in the world．
D．The India harvests 10，000megawatts of electricity each day on average．
50．The passage is mainly written toD．
A．encourage more people to travel by train
B．explain the advantages of electricity
C．tell readers how to save energy and money
D．introduce a new invention to readers．

5．One of the most important things in the world is friendship．In order to have friends，you have to be a friend．But how can you be a good friend at school？
Listen-Listen when they are talking．Don't say anything unless they ask you a question．Sometimes it's not necessary for you to have anything to say； they just need someone to talk to about their feelings．
Help them-If your friend is ever in need of something，be there to help them．You should try to put them first，but make sure you don't do everything they want you to do．Try to take an extra pencil or pen with you to classes in case they forget one．Have a little extra money in your pocket in case they forget something they need．
Be there for them-Try to make something for your friend to help make them feel better in hard times．Making cards and encouraging them are among the nicest things you can do for a friend．Marilyn Monroe，a famous U．S．actor，once said，"I often make mistakes．Sometimes I am out of control．But if you can't stay with me at my worst，you are sure not to deserve （值得） to be with me at my best．"Always remember this!If you don't want to stay with your friends when they're in hard times，then you don't deserve to be with them when they're having a good time!
Try to make plans with your friends．Go shopping，go for ice cream，have a party，go to a movie and so on．Take time to know each other even better by doing something you both enjoy．By planning things together，you both can have a good time．And you'll remember these things when you're all old!
