1 . Exercise could not only benefit your body, but also improve your memory, researchers found recently. In their paper published on Monday, researchers from the University of California, Irvine in the United States and the University of Tsukuba in Japan introduced their experiment and conclusion.

Scientists invited 36 volunteers who were in their early 20s to do 10 minutes of light exercise before taking a memory test in which they were shown pictures like broccoli（西兰花）or picnic baskets and asked to recall them later. The same experiment was repeated with the same group of volunteers without exercising. ^u The memory task was really quite challenging , "   said Michael Yassa,co-author of the study and a neuroscientist （神经科学家）at the University of California, Irvine. "We used very tricky similar items to see if they would remember whether it was this exact picnic basket versus （对抗）that picnic basket. "

Researchers also scanned brains of some, of the participants during the experiment. They found strengthened communication between regions involved in the storage and recollection of memories in brains of those who had exercised. This suggested that just 10 minutes of light exercise like walking,yoga or Tai Chi might increase memory power.

As all the volunteers in the experiment were relatively young, researchers are still working to look at the effects of light exercise on older people. "Our future goal is to try to develop an exercise prescription（处方） that can be used by older adults who might have disabilities or mobility impairments,but can still adopt very simple exercise rules of life and be able to,perhaps,delay cognitive decline temporarily," said Yassa.

2 . A six-wheeled robot travels underground in Hefei to discover warning signs of faults inside the pipeline network, "It looks like a toy car at first, but it's much more complicated than that," said Xu Mao, the robot 's operator.

The pipeline robot, developed by Wuhan Easy-Sight Technology, is made up of four parts — crawler, camera, cable reel, and controller. A full charge can enable the robot to work for four to five hours, covering a distance between 800 and 1 ,000 meters in the underground p ipeline.

The robot made its appearance last month in Shushan District. It will carry out inspections of the underground pipeline network stretching 150 kilometers. " Whether the pipe is leaking, damaged or blocked, we can clearly see its situation through high-definition(高清晰度的)cameras fixed into the robot, " said Qi Chuanshuai from the provincial construction engineering and testing institute.

The real-time data including video images of the pipe will be up loaded and displayed on a computer. "If we find any problems, we stop the robot and record the flaws," Xu said. "We report the faults to local government, who will arrange the repair as soon as possible. "

With the rapid develop merit of cities, it is becoming increasingly difficult to manage underground pipelines. Among all the difficulties, discovering faults in the sewage (污水)and rainwater pipelines comes first. Many other cities such as Wuhan, Nanjing, Shenzhen, and Shanghai are using the robots to inspect their pipelines, the robot ' s developer said.

Equipped with environmental detection sensors, the robots can monitor temperature and damp, poisonous gases, oxygen levels and smoke density, while providing color diagram in real time. "Compared with human workers, robots are able to enter smaller pipes and are immune (有免疫力的)to poisonous gases in sewage pipes," said Ge Shengli from Shushan District' s city management company. " No digging is required and there is no need to interrupt traffic," Ge added.

1. What does Paragraph 2 mainly tell us about the pipeline robot?

A．Its developer.

B．Its components.

C．Its characteristics.

D．Its outward appearance.

2. What is the toughest in managing underground pipelines in cities?

A．Locating the position where the pipelines are.

B．Handling the poisonous gases in sewage pipes,

C．Arranging the repair and maintenance of pipelines.

D．Discovering flaws in the sewage and rainwater pipelines.

3. What does the author intend to do in Paragraph 5?

A．Add some background information.

B．Introduce a new topic for discussion.

C．Summarize the previous paragraphs.

D．Present some new functions of robots.

4. What is Ge Shengli's attitude towards the pipeline robots?

A．Doubtful.	B．Appreciative.
C．Critical.	D．Indifferent.

8 . It was a morning in January. The jet stream (急流)had dipped down, causing the Arctic cold to reach the mountains of my home. It was only 2 degrees outside, but the cold wind made it feel like it was 15 below zero. Still, I was kneeling in the snow alongside my house trying to open a tiny door, so I eoukl get in. 1 had forgotten to leave my water dripping the night before and now my water pipes were frozen and my faucets(水龙头)were dry.

The wind cut into me like a knife while I struggled to get two electric heaters in place around the section of frozen pipes. The waterlines were buried except for a small piece that connected up to my house. I put a heater on each side of it, ran the extension cords(软线)into my house and plugged them in. Both heaters roared to life and started blowing hot air on the frozen water pipes. My fingers had already started to go numb, so I stayed inside to wait. I could only hope that this bit of warmth could get my water flowing again. Finally, after twenty minutes, the water started flowing through my faucets again. I went back outside into the biller cold and gathered my heaters up. I looked at the weak January sun shining on the frozen snow and smiled. Then I sent a joy filled with "Thank you" heavenward and returned inside to make myself a hot breakfast.

Sometimes the coldness of this life can get to us as well. It can make our hearts feel icy and frozen. It can keep our kindness and love from flowing out to others. Sometimes, though, all we need is a bit of warmth to get us going again. It can be a simple smile, a kind word, a heart-felt hug, a morning sunrise, a bird's song or any gentle reminder of just how much God loves us. Let us all be grateful for those bits of warmth that gel us going again. And let us all try to be that bit of wannth for others every chance we get.

1. What was the direct reason why the water pipes were frozen?

A．The jet stream.

B．The low temperature.

C．The cold wind.

D．The author ' s own carelessness.

2. Which of the following can replace the underlined phrase "roared to in Paragraph 2?

A．Began functioning smoothly.

B．Worked inappropriately.

C．Broke down suddenly.

D．Screamed out loudly.

3. What did the author think of his work?

A．Embarassed.

B．Satisfied.

C．Mad with joy.

D．Cautiously optimistic.

4. What is the last paragraph mainly centered on?

A．The coldness of life has a negative effect on our life quality.

B．We meet with the coldness of life unavoidably and unwillingly.

C．We should be thankful for bits of warmth of life.

D．We should seize every chance to receive warmth of life from others.
