26、 The world has a water problem which is simple to understand but not to solve. The amount of water in the world is limited. Water usage in the world has increased during the past 10 years. Usages will continue to increase as the population grows and uses more water. A third of the world’s population lives in countries that have too little water. 【1】
It’s strange to think that there is more than enough water available for everyone’s basic needs. 【2】 Some countries are much drier than others, for example Sudan in Africa. The UN says that people need a minimum of 50 litres of water a day for drinking, washing, cooking and sanitation(卫生). In 1990, over a billion people did not have even that . 【3】 Water shortages can mean long walks to get water, high prices to buy it, food insecurity and disease from drinking dirty water.
Governments that try to improve water supplies need to think carefully about how to do this. Dams and other large projects now affect 60 percent of world’s largest rivers and provide millions with water. 【4】
【5】 New technology can help, especially by cleaning up pollution and so making more water usable, and in agriculture, where water use can be made far more efficient. For millions of people around the world, solving the problem is a matter of life and death.
A.So what can help?
B.The rest along major rivers in the world have no worry about water.
C.Unfortunately, it’s poor people who suffer most.
D.By 2025, scientists expect this to increase to two-thirds.
E.It’s just not spread evenly throughout the world.
F.Meanwhile, electricity from these dams can provide people with clean energy.
G.But in many cases, homes and the environment are destroyed as a result.
27、 On the night of August 24, 2001, my last night of freedom before my freshman of high school started, everything changed when my friend's car hit a guardrail(护栏) with me inside.
I lost most of my right leg. At the hospital, I just kept telling myself to hold on. Weeks later I made a deal with the hospital staff that once I could roll onto my side, I could be discharged. I am proud to say that just one short week later, I was going home. The day I left the hospital, I made a promise to myself to never give up and to always live life to the fullest.
In February of 2013, my life was forever changed when I attended the Executive Assistant Organization's Behind Every Leader event. During the conference, a sweet lady by the name of Alisson Frew dared to ask me why I did not wear a prosthesis(假肢). My short and simple answer was, "I don't have sixty thousand dollars." The next morning I was in tears as I learned that Alisson, Jeff Hoffman, founder of Priceline, and a dozen other people, had bought a prosthesis for me. From the first step, it was apparent to me just how much this would mean to me.
For a year I adjusted to the leg and settled into everyday life, until one day I realized I was making a life but not living one. After almost 13 years of thinking that I was confident, I had an unfamiliar feeling sweep over me. For the first time in my life, I was not only confident but I was empowered! I desired to help those around me, to have them experience this unbelievable feeling for themselves.
In April of 2014, I started modeling. My dream is that one day a little girl will see me on a poster at her favourite clothing store and say, "Wow, she is amazing, and she only has one leg. I could do that too someday, even though I have a disability."

28、 The Tibet autonomous region has placed nearly half its land area under the strictest ecological supervision (监督).It was announced at an annual meeting of the regional People's Congress, which kicked off on Wednesday.
The ecological protection area, which covers more than 539,000 square kilometers, makes up 45 percent of the region's area, and 22 ecological reserves have been built and are operational.
According to the government work report, the rate of days with good air quality in Tibet's cities has reached 99.4 percent, and all the region's drinking water sources have met applicable standards.
The report also said that the number of Tibetan antelope (羚)in the region has risen to more than 200,000, wildlife species to 1,072 and black-necked cranes to more than 8,000. Five rare new species have been discovered in recent years. The region has spent 12.2 billion yuan ($1.9 billion) on ecological protection projects in recent years. Five cities and three counties have been named as national-level ecologically civilized model cities and counties, and more rural residents have benefited financially by undertaking part-time ecological protection work.
More advanced monitoring facilities have been in place in the reserve, with more ecological protection inspectors employed to undertake protection work. The professional ecological inspectors are provided with basic tools such as motorcycles, telescopes and paging receivers, and they provide feedback regularly. Professional inspectors also receive one week of training every year from professors at Tibet University.
Kunsang Darje, a railway maintenance worker in Nagchu, said that apart from maintaining the railway and highway, he also collects trash along the section with his colleagues. “The place I work is in a no-man's land, and I think it's very important to protect the animals there without affecting them with human activities, and we are also bound to take responsibility there," he said.

Knowledge is free on the Internet at a small but 【1】 number of colleges and universities. About 160 schools around the world now put free course materials on the web to the 【2】. Recent additions in the United States 【3】 projects at Yale, Johns Hopkins and the University of California, Berkeley.
Berkeley said it would offer videos of lectures on YouTube. Free videos from other schools are 【4】 at the Apple iTunes store.
The Massachusetts Institute of Technology (MIT) became an early 【5】 with its Open Course Ware project, first 【6】 in 2001. Free lecture notes, exams and other resources are published at ocw.mit.edu. Many exams even include the answers. Today, Open Course Ware offers materials from 1,800 undergraduate and graduate courses. These 【7】 from Physics to Political Science. Visitors can learn the same things as MIT students learn. But as the site points out, Open Course Ware is not an MIT education. Visitors receive no credit toward a degree. Some materials from a course may not be available, and the site does not provide 【8】 with teachers. Still, MIT says that the site has had forty million visits by thirty-one million visitors from almost every country. Sixty percent of the visitors are from outside the United States and Canada. Students and educators use the site, including students at MIT. But the largest number of visitors, about half, are self-learners.
Some professors have become well-known around the world as a result of 【9】 online. Walter Lewin, a physics professor at MIT, is 【10】 popular. Fans enjoy his entertaining lectures. MIT Open Course Ware now includes materials for high school. The aim is to improve education in Science, Technology, Math and Engineering.

Why Cold weather Causes So many Flight Cancellation?
Each year, about 60,000 flights get canceled because of bad winter weather, which costs airlines and airports an estimated $3 billion. But it’s not the freezing cold temperatures that cause problems for planes. After all, 【1】 jets fly 10 kilometers up, where temperatures hover around -50 degrees Celsius.
In fact, planes 【2】 in cold weather, since cold air is denser and leads to better thrust. Clearly, the real problem isn’t what’s going on up there. It’s what’s happening on the ground.
When a 【3】 polar vortex (极地涡旋) struck the Midwestern US in January 2019, temperatures dropped to -40 degrees Celsius and airline canceled 3,000 flights nationwide. In these situations, when temperatures start 【4】, everything slows down. Cargo doors can freeze up, along with the nozzles that pump fuel into planes, which delays the 【5】 process.
Even the plane itself can freeze over. Just a quarter-inch - thick layer of ice on a plane can disrupt the way air flows over its wings.
Les Westbrooks: The number one reason, I would say, that the reason flights get delayed in cold weather is going to be because there’s some kind of frozen precipitation, from frost to snow to a sheet of ice, adhering to the aircraft, adhering to the wings of the aircraft 【6】.
That’s Les Westbrooks, a retired airline pilot and an associate professor of aeronautical science at Embry-Riddle Aeronautical University. He says that 【7】, these planes are “de-iced” - but this also delays takeoff. The crew can spray the plane with a special hot water/ glycol mixture. It can take around 40 minutes to de-ice large passenger airplanes, so planes often have to wait “their turn” for the de-icing station, which, of course, can trigger more delays.
And ice on the runway, of course, creates another set of 【8】. In 2014, a plane at JFK skidded off an icy runway and into a mound of snow, leading to an hours-long shutdown at the airport. And even though crews can remove ice from the runway, scraping it off the pavement can lead to potholes (坑洞) and other 【9】, which makes takeoffs and landings more dangerous. And of course, snow and freezing rain on the ground can affect visibility to the point where officials have to decide it’s not safe to fly at all.
But if ice and snow aren’t the problem in these extremely cold temperatures, it’s usually another factor: people.
Les Westbrooks: The airplane flies at high altitudes, -60 degrees. It’s made to do that. Humans are not made to be outside in -60 degrees weather. And so the human factor becomes a big, big factor, when it becomes extremely cold.
Baggage handlers, aircraft fuelers, and mechanics all have to stay warm. Some airports, like O’Hare in Chicago, set up heated shelters for their employees. Of course, with everyone taking breaks to warm up, not as much gets done, which leads to even more delays and cancellations. Passengers start missing their 【10】 flights, and that, along with passengers who can’t make it to the airport due to bad road conditions, leads to half-empty planes.
In fact, many airlines might preemptively cancel flights before bad weather even hits. So, in the end, you can still blame cold weather for cancelling your flight.

Driving an electric car 【1】 to the protection of environment, or so the marketing departments of their makers would have you believe. Yet a report which analyzes car emissions presents a rather different picture. A battery-powered car recharged with 【2】 generated by coal-fired power stations, it found, is likely to be more harmful. It could cause more than three times as many deaths from pollution as a 【3】 petrol-driven vehicle.
The study was carried out by the University of Minnesota. The researchers estimated how levels of fine particulate matter (细颗粒物) and ground-level ozone — two important 【4】 of air pollution — would change when a car is powered by different ways.
It was no surprise that electric cars whose batteries were recharged with power from wind, solar or hydro-electric sources came out to be virtually free from harmful 【5】. They were estimated to cause 231 deaths over the course of a year, compared with 878 for petrol cars. Electric cars recharged with power from natural gas-fired stations were also a lot less harmful than petrol-driven ones, with 439 deaths. But if those same electric cars were recharged 【6】 by coal, they would be responsible for over 3,000 deaths.
Biofuels also caused more health problems than petrol. But diesel, which often 【7】 concern about pollution, is slightly cleaner than petrol. This is because the study assumes for all cars that emission-control technologies will be more widely used, especially particulate filters which have a remarkable effect on cleaning diesel 【8】. Diesel cars are also more 【9】 of fuel than petrol-driven ones.
Overall, the study shows that electric cars are cleaner than those traditional vehicles only if the power used to charge then is also clean. That is hardly a surprise, but the 【10】 of the difference is. How green electric cars really are, then, will depend mainly on where they are driven. In France, which obtains more than half of its power from nuclear station, electric cars look like a good bet. In China and some other developing countries, where a large amount of electricity is produced from coal, they may not be so environment- friendly as they are marketed.
