21、Traffic Accidents and Road Safety
The number of road accidents and the deaths arising from those accidents has increased greatly over the past year. 【1】.
We must all be aware of the causes of traffic accidents and act to prevent them. This is true of everyone as accidents affect driven of vehicles as well as cyclists and pedestrians. We all have a responsibility to prevent accidents. Here are some of the major causes of road accidents.
●Driven not paying attention
This is the most common cause of accidents. 【2】 they are not prepared when another driver does something wrong, like changing paths without signalling or giving wrong signals.
●Drivers being impatient in a traffic jam
Many drivers are aggressive and push into other paths of traffic or overtake other cars. These are both very dangerous because they can easily lead to crashes.
●【3】
Recently the number of people fined for speaking on their mobile phoned while driving has increased by 30 percent. Speaking on the phone requires concentration and takes a driver's attention from the road.
●Drinking and driving
If you drive after you have had alcoholic drinks, you are breaking the law and risking your own life as well as the lives of others 【4】, even if they have had just couple of beers, do not allow them to drive.
●Drivers speeding
Speed kills This is a fact that is easily overlooked, but driving too fast through city streets is very irresponsible and dangerous. Our city streets are away busy with people, cars and bicycles. 【5】. They should be especially careful near schools, where there are likely to be many children.
A.Road safety for pedestrians
B.Divers speaking on mobile phones
C.Drivers must watch out for people crossing the road
D.Unless driver's drinking alcohol is absolutely banned
E.When drives do not pay attention to surrounding traffic
F.If you are with someone she who has been drinking alcohol
G.This notice is aimed at increasing people's awareness of the problem
22、Contribution And Sacrifice
Huang Danian, the renowned Chinese geophysicist, was born in 1958 in Guangxi, China. As a keen and able student, Huang went to the UK in 1993 to further his studies.
By the time Huang moved back to China in 2008, he had been living and working in the UK for 15 years. He had a good job and a life there, but he gave it all up to return to home, driven by the idea that he needed to contribute to his country. As one of the world’s leading experts in deep earth exploration technology, Huang was approached to participate in the “Thousand Talent” programme. He took up a position at Jilin University, Changchun.
Huang was named lead scientist on China’s deep earth exploration programme, developing advanced cameras that can see through the Earth’s crust so that it can be analysed without having to dig into it. He set up a state-of-the-art lab, sometimes paying for equipment with his own money. Some described him as a “lunatic” (a madman). but this passion and drive enabled Huang to propel China’s deep earth exploration technology into a world-leading position. Huang’s dedication contributed to China’s lunar probe Yutu being landed on the moon in 2013 and the launch of the spacecrafts Shenzhou-11 and Tiangong-2 in 2016.
Huang’s health also paid the price for his commitment to his word. He began having fainting fits in 2012, but paid them little attention, stating he did not have time to go to see a doctor – his work always came first. In November 2016, Huang collapsed and was taken to hospital, where he was diagnosed with cancer. The disease was so advanced that he had just a couple of months to live.
Like the true scientist he was, Huang never gave up, but always tried to push forwards. Even from his hospital bed, he continued his work, writing letters of reference for his colleague and replying to questions from his students. He had great faith in the talent of the up-and-coming generation, “Our country is in urgent need of talented people,” he said. “If we spend more time and pay more attention to the young, masters and even Nobel prize winners may rise among them.”
Huang died in January 2017, aged just 58. More than 800 people attended his funeral to celebrate a life that burned so bright, but was so short.

D.Passionate and considerate.
23、 Cells in our brain usually send “stop eating” signal when we’ve had enough. But after mice ate fatty foods for just two weeks, their brains’ brake on overeating quieted down. That finding may help explain the complex link between food and appetite that can become disordered when people overeat.
Food is essential to life. Our brains have, therefore, evolved a series of systems to make sure we eat enough. Garret Stuber, a neuroscientist at the University of Washington, together with his team took aim at one brain area known to be involved in eating behaviors.
This lateral hypothalamus (下丘脑外侧区) contains many diverse cells Stuber’s group looked at the behaviors of genes in the cells here. And in one type—glutamatergic nerve (谷氨酸能神经) cells—big differences appear between fat mice and lean ones.
Earlier work by Stuber’s group had suggested that these cells act like a brake on eating. When the researchers prevented these cells from firing, mice suddenly overate. They also fattened up. But it wasn’t clear how the cells’ activity changed as the mice transitioned from slim to fat.
“Obesity doesn’t just happen overnight,” notes Stuber. To find out the secret, his group undertook a new study. They fed mice high-fat food. Now and again, they’d use a fancy microscope to look at how well the animals’ glutamatergic cells could fire off signals.
Two weeks into the high-fat food—even before the mice became round – the activity of these nerve cells had slowed. It continued as the animals grew larger over a 12-week period. “The cells’ activity was going down as a function of high-fat diet. The results suggest that the high-fat diet is removing the brake on eating and obesity,” explains Stuber.
It’s hard to say whether similar cells normally control people’s appetite. Brain-imaging tests have shown that the same brain region —the hypothalamus—plays a role when people shift between hunger and feeling full.
【1】What happened after the mice ate fatty foods for two weeks?
A.Their appetite was getting worse. B.Their brains became disordered.
C.They refused to eat zero fat food. D.They lacked a feeling of fullness.
【2】It can be learned from the text that glutamatergic nerve cells ________.
A.are easily found in lean mice B.can prevent mice from overeating
C.function well under any condition D.are a main part of lateral hypothalamus
【3】Why did Stuber’s group undertake the new study?
A.To study the role of glutamatergic cells in mice’s fattening up.
B.To find out the link between high-fat diets and obesity.
C.To find out deciding factors in mice’s appetite.
D.To study the eating habit of fat mice.
【4】What is the main idea of the text?
A.Obesity influences glutamatergic nerves’ function.
B.Glutamatergic nerves decide people’s appetite.
C.High-fat diets lead to overeating.
D.Our brains control our food choices.

25、Trackers on Ice
Just because a scientist puts a GPS tracking collar on a wild polar bear does not mean the animal will obligingly keep it on._______________, these huge collars are purposefully loose.If one becomes annoying, a bear can _______________ it.But scientists have now found a way to use _______________ from the discarded(丢弃的)devices.
"These dropped collars _______________ would have been considered garbage data," says Natasha Klappstein, a polar bear researcher at the University of Alberta.She and her colleagues instead used _______________ from such collars, left on sea ice in Canada's Hudson Bay, to track the ice itself.For their study, published in June in The Cryosphere, the researchers identified twenty collars that transmitted movement data in line with ice drift rather than polar bear _______________ between 2005 and 2015.The resulting records of how melting ice typically drifts in Hudson Bay are unique.There are no easily _______________ on-the-ground sensors, and satellite observations often cannot accurately capture the motion of small ice sheets.
The team _______________ the discarded collars' movements with widely used ice-drift modeling data from the U.S.National Snow and Ice Data Center(NSIDC).Collar data indicated that the NSIDC model underestimates the speed at which ice moves around in Hudson Bay-as well as the overall _______________ of drift.Over the course of several months, the model could drift away from an ice sheet's location by a few hundred kilometers, the researchers say.
This means the bears may be working harder, when moving against the direction of the ice, than scientists had ________________: "Since we're underestimating the speed of drift, we're likely underestimating the energetic effort of polar bears," says Natasha Klappstein.The research reveals ________________ insight into how highly mobile ice moves.As melting increases in the coming years, such ice will likely become more ________________ farther north, in the central Artic.Scientists had known NSIDC data could underestimate drift speeds, but "any time we can find a data ________________, it is a good thing."
Plus, such data could improve predictions about how oil spills or other pollutants may ________________ in seas.littered with drifting ice, says Walt Meier, a senior NSIDC research scientist, who was not involved in the study.The findings may even ________________ future NSIDC models: "It's a really nice data set," Meier says."And certainly one we'll take under consideration."
