A Chinese rocket carrying a probe（探测器）destined（预定） for the moon has been sent into space.
A Long March 3C rocket with the Chang’e -2 probe took off from Xichang launch centre at about 11: 00 GMT.
The rocket will shoot the craft into the trans-lunar orbit（绕月轨道）, after which the satellite is expected to reach the moon in about five days. Chang’e -2 will be used to test key technologies and collect data for future landings. China says it will send a rover（漫游者） on its next mission, and it also has ambitions to put humans on the surface of the lunar body at some future date. The Xinhua News Agency said Chang’e -2 would circle just 15 km (nine miles) above the rocky terrain（地带）in order to take photographs of possible landing locations.
It is China’s second lunar probe—the first was launched in 2007. The craft stayed in space for 16 months before being intentionally crashed onto the moon’s surface. China launched its first manned flight into low-earth orbit in 2003; and two more followed, with the most recent one in 2008. So far, only three countries have managed to independently send humans into space: China, Russia and the US.
In 2008, a Chinese astronaut, fighter pilot Zhai Zhigang, performed a spacewalk—the first in China’s history. He stayed outside the Shenzhou-7 capsule for 15 minutes; the exercise was seen as the key to China’s ambition to build an orbiting station in the near future.
67. What’s Chang’e -2’s main task according to this passage?
A. Landing on the moon just as the first lunar probe.
B. Comparing with the first lunar probe.
C. Competing with Russia’s and the US’s space craft.
D. Testing technologies and collecting data for future landings.
68. Which of the following about Chang’e -2 is TRUE?
A. Its travel to the moon lasts about five days.
B. It will put humans on the surface of the moon.
C. It travels with Long March 3C rocket all the way.
D. It will take photographs of the moon on the trans-lunar orbit.
69. Which of the following is the best title for the passage?
A. China Launches Moon Mission
B. Chang’e -2 Is More Advanced than Shenzhou-7
C. China’s Space Program Makes Great Progress
D. China Equals Russia and the US in Space Technologies
70. The underlined word“craft” in the third paragraph refers to_____.
A. Chang’e -1 probe
B. Chang’e -2 probe
C. a rover
D. the Shenzhou-7 capsule

"How did you write your advertisement?" asked one of the listeners, a merchant.
"Here it is," said the man, taking out of his pocket a slip（纸条） cut from a newspaper. The other man took it and read, "Lost from the City Church last Sunday evening, a black silk umbrella. The gentleman who finds it will receive ten shillings（先令） on leaving it at No.10 Broad Street."
"Now," said the merchant, "I often advertise, and find that it pays me well. But the way in which an advertisement is expressed is of extreme importance. Let us try for your umbrella again, and if it fails, I'll buy you a new one."
The merchant then took a slip of paper out of his pocket and wrote: "If the man who was seen to take an umbrella from the City Church last Sunday evening doesn't wish to get into trouble, he will return the umbrella to No. 10 Broad Street. He is well known."

China is going green．In order to reduce air pollution and oil shortages, carmakers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market．Toyota’s hybrid car Prius will be ready to drive in China this week．Let’s have a look at the new car．
Any vehicle is a hybrid run on a rechargeable battery and gas．Hybrid cars have special engines, which are smaller than traditional gas engines．The gasoline engine provides 99 percent of the power when the car is going at a steady speed. A specially designed battery motor provides extra power for running up hills or when it needs to speed up．
Step into a Prius, and turn on the engine．The first thing you notice is that it is quieter than a traditional car．At this point, the car’s gas engine is at rest．The electric motor will provide power until the car reaches about 24km/h．If you stay at a low speed, you are effectively driving an electric car, with no gas being used, and no waste gas given off．
The computer decides when to use the gas engine, when to go electric, and when to use a combination of the two．If you go over 24km/h, when you step on the gas pedal (油门), you are telling the computer how fast you want to go．
The electric motor recharges automatically using a set of batteries．And when driving at a high speed, the gas engine not only powers the car but also recharges the batteries．When you use the brake, the electric motor in the wheels will work like a generator (发电机) to produce electricity to recharge the batteries．As a result, the car’s batteries will last for around 200,000 miles．
66．The underlined sentence probably means ________.
A．there will be more and more green land in China
B．China’s new cars are combinations of different green models
C．China is still young and lacking in experience
D．the environment is getting better in China
67. What is the most important feature of hybrid cars?
A. They are powered by both a rechargeable battery and gas.
B. They have smaller engines than traditional gas ones.
C. They only use 99 percent of their power to run up hill.
D. They are much quieter than traditional cars.
68. We can know from the story that ________.
A. the gas engine recharges the batteries as well as powering the car
B. using the brake suggests that the gas engine should work
C. the car’s batteries will last for around 200,000 miles without being recharged
D. the batteries can be recharged at any time you want
69. The author writes the passage mainly to________.
A. announce plans to develop hybrid vehicles for the Chinese market
B. let people know how to save their gas when driving a car
C. teach people how to drive a hybrid car
D. introduce a new kind of “green” car
70．Which of the following statements is TRUE according to the text?
A．The hybrid car is environmentally friendly．
B．The hybrid car is unable to get itself recharged．
C．The hybrid car has been made in mass．
D．The hybrid car can decide what power to use

A lot of teachers hate doodlers(乱写乱画的人)during classes．“Pay attention!” Teachers will often warn doodling students，sure that they must be daydreaming．
However, according to a recent study, doodling while listening to a boring lecture helps concentrate the attention：
Andrade，a psychology professor in England asked participants to listen to a boring lecture． Half the participants were told to color in squares and circles freely on a piece of paper while listening to the lecture. The other half weren’t given a task．After it was over, the participants were asked to retell the lecture．
Those given the doodling task(color in squares and circles)remembered 29 percent more information than the non-doodlers．Andrade said．
“If someone is doing a boring task，like listening to a dull conversation，they may start daydream，”said Professor Andrade．
“Daydreaming distracts(使分心)them from the task，resulting in poorer performance．A simple task，like doodling，can stop them from daydreaming without affecting their performance at the task，”he said．
So the next time you’re doodling during a class，and you hear “pay attention”，you can tell the teacher with confidence that you’ve been paying attention to every word．
66．The passage mainly tells us ．[来源:ZXXK]
A．doodling will be banned in classes B. teachers are against doodling

67．Teachers hate doodlers because they thought ．

A．those given the doodling task can remember less information
B．if you have daydream during classes you’ll have a good memory
