21、A friend of mine named Paul received an expensive car from his brother as a Christmas present．On Christmas Eve when Paul came out of his office，a street urchin (顽童) was walking around the shining car．“Is this your car，Paul？” he asked．Paul answered，“Yes，my brother gave it to me for Christmas.” The boy was surprised．“You mean your brother gave it to you and it did cost you nothing？Boy，I wish…” He hesitated．
Of course Paul knew what he was going to wish for．He was going to wish he had a brother like that. But what the boy said surprised Paul greatly. “I wish,” the boy went on，“that I could be a brother like that.” Paul looked at the boy in surprise, then he said again, “Would you like to take a ride in my car？”
“Oh yes，I'd love that．”
After a short ride，the boy turned and with his eyes shining，said，“Paul，would you mind driving in front of my house？”
Paul smiled a little．He thought he knew what the boy wanted．He wanted to show his neighbors that he could ride home in a big car. But Paul was wrong again. “Will you stop where those two steps are？” the boy asked．
He ran up to the steps. Then in a short while Paul heard him coming back, but he was not coming fast. He was carrying his little disabled brother. He sat him down on the step and pointed to the car.
“There she is, Buddy, just like I told you upstairs. His brother gave it to him for Christmas and it didn't cost him a cent. And some day I'm going to give you one just like it…then you can see for yourself all the nice things in the Christmas windows that I've been trying to tell you about.”

22、 Scientists in the U.S. have created an artificial sunflower less than 0. 04 inches wide that can bend towards a light source and harvest solar energy. The flowers were found to be about 400 percent more efficient than other equipment, making them promising technology for solar power potentially even as a power source for solar-based spaceships.
The team, led by researchers from the University of California, Los Angeles, was looking to improve. the efficiency of solar cells by modeling after a feature of nature-phototropism. This is where a plant adjusts itself to face the sun, getting the most amount of energy it can get. In a study published in Nature Nanotechnology, the team said it was a 'big challenge'.
However, this problem has now been overcome. The team has developed a polymer(聚合物) that is responsive to being simulated by light, The system, which they have named SunBOT for short, is able to instantly explore and track a light source. It can do this across a range of temperatures without power supply or any human intervention.
The researchers used the polymer to create a 'stem'. Then they placed a material commonly used in solar cells on its top, representing the 'flower'. When the team shone a light at the SunBOTs, the polymer began heating up and shrinking, causing the stem to bend so the flower faced the light.
The researchers tested their artificial sunflowers to see how efficient they were at harvesting solar energy Findings showed they were up to 400 percent more effective than non-phototrophic materials.
The practical applications of SunBOTs are some way off. The study shows a proof of concept, but the technology will need to be scaled up to be used commercially. However, the team is confident it could one day be used a across a broad range of industries.
This work may be useful for solar harvesters signal revere smart windows, self-contained robotics solar sails for spaceships and intelligent energy generation (for example, solar cells and biofuels), the scientific team said.
【1】Why do the scientists create the artificial sunflower?
A.To prevent pollution. B.To protect sunflowers.
C.To reuse green energy. D.To warn us of the energy crisis.
【2】What can we learn about SunBOTs?
A.SunBOTs are likely to be too limited in future use.
B.There is some time before SunBOTs are put into markets.
C.Scientists are still not sure of the function of SunBOTs.
D.SunBOTts are not efficient, though advanced, in collecting energy.
【3】Where can we read such a text?
A.In an education report. B.In a market report.
C.In an experiment report. D.In a science report.
23、Our brain is a remarkably powerful tool. It is able to provide you with much more thinking abilities if you learn how to develop it in the most efficient way. 【1】
● Try to give your habits a fresh start from time to time.
For instance, stand on another foot when getting out of bed. You can also switch to holding a tooth brush with a hand you’ve never used for this purpose before. 【2】
All of those simple (yet amusing) tasks will help you to increase your brain’s activity.
● Learn how to get proper rest in order to work efficiently.
Deep healthy sleep increases brain’s strength margin and contributes to attention focusing. A lack of sleep or its’ derangement may affect mental activities and remarkably decrease its’ functional level. 【3】
● Do outdoor exercise
It is scientifically proven that a reasonable outdoor exercise forces your brain to produce new cells. There’s no need to become an athlete, but a bit of jogging around the building will definitely do you no harm.
● 【4】
Walnuts are the best snack for a brain - these even share a similar shape. Five walnuts a day provide enough lecithin for improving brain activity and memory. Don’t drink too much alcohol, for it isn’t good brain food.【5】 It is a part of a brain responsible for memory and spatial orientation. And well, a drunk man simply looks pitiful and foolish.
A．Choose the best brain food.
B．Don’t drink alcohol without limitation.
C．Scientists recommend a period of 6 to 8 hours of daily sleep.
D．Here are some simple ways to increase brain activity.
E．Alcohol destroys hippocampus.
F．Alcohol does harm to health.
G．Give it a go and experiment with the way you’re not used to walking.
24、A new “museum of mathematics” will open in Paris as part of a drive to inspire French schoolchildren, who rank among the worst in the developed world.
The Maison Poincaré, named after Henri Poincaré, the late 19th century polymath, will celebrate mathematicians who put France at the forefront of the subject from the middle ages to the 21st century.
The museum, set to open this year, is attempting to spark a renaissance in the face of an educational failure that is viewed as a national emergency.
French pupils ranked bottom in the subject in the EU, while only those from Chile fared worse than the French among the 38 countries of the OECD, according to a Trends in International Mathematics and Science study.
Their poor grasp of the subject was further highlighted by the fact that half of French 12-year-olds thought 0.4 was the same as a quarter, Charles Torossian, aninspector-general of the national education system, said.
In addition, the children of Ukrainian refugees were, despite the language barrier, at least a year ahead of their French classmates in calculating ability.
The museum was the innovation of Cédric Villani, former director of the Poincaré maths institute and former MP for Macron’s Renaissance party.
Sylvie Benzoni, his successor as head of the institute, said the museum aimed to show that maths was open to everyone and no longer the property of “a mainly male scholar”.
Last summer President Macron recovered maths as an option in the general examination, two years after Jean-Michel Blanquer, his education minister, had removed it. He fired Blanquer and last month made weekly maths classes necessary for all grades from September.
【1】The new museum will open in Paris ______.
A．to exhibit the artistic achievements of renaissance in Europe.
B．to correct the educational failure which is regarded as a national emergency.
C．to encourage the children in France to learn mathematics better.
D．to remind the French schoolchildren that they rank among the worst in the developed world.
【2】What does the underlined word “those” in the fourth paragraph refer to?
A．subjects.
B．pupils.
C．countries.
D．museums.
【3】What is the direct reason of Jean-Michel Blanquer’s unemployment?
A．He made mathematics the property of “a mainly male scholar”.
B．He cut maths down from the general examination.
C．He taught the French 12-year-olds that 0.4 was the same as a quarter.
D．He didn’t think weekly maths classes necessary for all grades.
【4】What is a suitable title for the text?
A．France Will Not Bear Her Poor Maths Any More.
B．Children Around The World Do A Bad Job In Maths.
C．French Schoolchildren Rank The Worst In The Developed World.
D．A New “Museum of Mathematics” Will Open In Paris.
