举一反三
Water shortage , already serious in Egypt and Sudan , will soon influence several other countries in the watershed as well.Today, about 160 million people depend on the Nile River for their living.Within the next 25 yeas ,the district"s population is expected to double, adding to the demand brought about by growth in industry and agriculture.The frequent drought(干旱)adds to the urgency.
Water quality is also a problem.Precious soil is washed out to sea.Wastes from industry and agriculture create pollution.Higher concentrations of salt influence irrigated soils.Water-borne diseases continue unchecked.In areas where it"s hot and damp, water hyacinths choke off(阻止) lakes, dams and other sections of the river, making it difficult for fishing and other businesses to move forward.
Native people along the narrow area of farmland have watched the sand move closer day by day.They’ve seen the river change course, and their only source(来源) of water thickened with mud.They’re very poor and have few choices.
But a new program, the Nile Basin Initiative (NBI), is offering very practical assistance.The program is more than just a water-management project.It’s a plan for the social and economic development of a vast district: it concentrates on the needs of the poorest of the poor and the environment that supports them.
These are whole ecosystem problems, calling for united solutions.Half the Nile Basin"s countries are among the world"s poorest nations;yet, somehow, they must find the resources, skills and political will to overcome these challenges.
小题1:What are the great challenges the Nile Basin faces?
A.The development of shipping industry. |
B.Over fishing of native people. |
C.Water shortage and water quality. |
D.Increasing population and tourism. |
A.plants | B.animals | C.rocks | D.salts |
A.preventing water pollution |
B.improving living condition of the poor |
C.changing the river course |
D.preventing land from becoming desert |
A.People’s Life in Egypt and Sudan |
B.Frequent Drought in Egypt and Sudan |
C.The Poorest Countries in the Nile Basin |
D.The Ecosystem Problems in the Nile Basin |
“Global warming is having a great effect on hundreds of plant and animal species around the world, changing some living patterns.” scientists say.
Increased carbon dioxide (CO2) in the air from burning coal and oil can have an effect on how plants produce oxygen, while higher temperatures and changeable rainfall patterns can change their patterns of growth.
“Predicting species’ reaction to climate change is a major challenge in ecology,” said the researchers of several U.S. Universities. They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.
The study, published on the Nature website, uses the findings from plant life cycle studies and experiments across four continents and 1,634 species. It found that some experiments had underestimated the speed of flowering by 8.5 times and leafing by 4 times.
“Across all species, the experiments underestimated the speed of the advance—for both leafing and flowering—that results from temperature increases,” the study said.
“The design of future experiments may need to be improved to better predict how plants will react to climate change,” it said.
Plants are necessary for life on the Earth. They are the base of the food chain, using photosynthesis (光合作用) to produce sugar from carbon dioxide and water. They let out oxygen which is needed by nearly every organism on the planet.
Scientists believe the world’s average temperature has risen by about 0.8 ℃ since 1900, and nearly 0.2 ℃ every ten years since 1979.
So far, efforts to cut emissions of planet-warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2 ℃ this century—a point scientists say will bring the danger of a changeable climate in which weather extremes are common, leading to drought, floods, crop failures and rising sea levels.
小题1:What is the key information the author wants to give in Paragraph 1?
A.The increasing speed of flowering is beyond scientists’ expectation. |
B.Climate change leads to the change of food production patterns. |
C.Plants’ reaction to weather could have damaging effects on ecosystem. |
D.Food chains have been seriously damaged because of weather. |
A.scientists should improve the design of the experiments |
B.plants’ flowering is 8.5 times faster than leafing |
C.there are 1,634 plant species on the four continents |
D.the experiments failed to predict how plants react to climate change |
A.they can prove the climate change clearly |
B.they are very important in the food chains |
C.they play a leading role in reducing global warming |
D.they are growing and flowering much faster than before |
A.It has risen nearly 0.2 ℃ since 1979. |
B.It is 0.8 ℃ higher in 1979 than that of 1990. |
C.It needs to be controlled within 2 ℃ in this century. |
D.Its change will lead to weather extremes. |
Many people like to watch others play games. They buy tickets or turn on their TVs to watch the games. Often they get very excited when “their” player or team wins.
Some sports are so interesting that people everywhere go in for(参加) them. Football, for example, has spread(展开)around the world. Swimming is popular in all countries near the sea or in those with many rivers. What fun it is to jump into a pool or lake, whether in China, Egypt or Italy! And think of people in cold countries. Think how many love to skate or ski (滑雪) in Japan, Norway or Canada.
Some sports or games go back thousands of years, like running or jumping. Chinese wushu, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time. Water-skiing is one of the newest in the family of sports.
People from different countries may not be able to understand each other, but after a game together they often become good friends. Sports help to train a person’s character. One learns to fight hard but fight fair, to win without pride and to lose with grace(胜不骄,败不馁).
小题1:Why do people all over the world enjoy sports?
A.Because they are healthy. |
B.Because they are happy. |
C.Because they want to live longer. |
D.All the above. |
A.their favourite team wins | B.they win the game |
C.they get the good news | D.they can’t help themselves |
A.they train their character in the game |
B.they understand each other |
C.they are friendly to each other |
D.they help each other |
The Lewisvillle, Texas, school teachers were aware that the hours they spent on preparing lessons were too often wasted on many students. So Forestwood High School, Texas, used the “flipped (翻转的) classroom” method of instruction. “We’ve completely done away with our lecture,” Derow said. And homework assignments “are all done in class,” Bradley said.
With the flipped concept, a student’s usual homework assignment is to watch pre-recorded lectures on their computers or smart phones.They walk into class ready to discuss the topic, collaborate(合作) with other students and work on assignments based on what they learned from the video. Free from lecturing, the teachers can use class time to look deeper into the subject and focus on difficult concept. As students change from a passive to an active role, they learn critical thinking skills, learn to collaborate and become independent learners.
Instead of doing homework assignments alone at home, students are now “working together, talking about it,” Bradley said. “If they don’t agree on an answer, they debate it and have to justify their answers. It’s a higher level of learning.”
Her students give the flipped classroom high marks.
Sarah Lee, 14, watches the 30-minute videos on a home computer. She likes the ability to rewind the tapes if she doesn"t understand a concept. She also likes being able to watch the lessons on her own schedule.
One of her classmates, Dawson Depperschmidt has the same idea and thinks the time she spends in the classroom is more productive. “It gives us more time to learn at school,” Dawson said. “You get more in-depth in class.

Hair color comes from the pigment melanin(黑色素), which determines your individual shade. Hair without any melanin is pure white. The pigment is produced in cells called melanocytes, which inject pigment into the hair. At some point in everyone"s lifetime, these cells slow down and eventually stop producing color. Scientists have yet to identify the exact mechanism by which melanocyte cell death occurs.
A study of more than 4,000 women and men from 20 countries determined that about 75% of people between the ages of 45 and 65 have some gray hair. In general, people of European descent gray earliest followed by Asians and Africans. It"s interesting to note that a lucky 1 in 10 has no gray hair by retirement age. Beginning at age 30, your chances of having gray hair go up 10-20% per decade.
It may feel like you have more grays after a stressful event, but that"s probably because middle age is basically a series of anxiety-ridden events. Between working, raising kids, and caring for older parents, the "sandwich" years of 45-65 can be stressful, especially for women. They are also when we naturally start to look older.
At this point, there is still no silver bullet to keep away the grays.

A.Going gray. | B.Tips to make hair color last |
C.Why does hair turn gray? | D.Gray hair is in fashion. |
A.Scientists have found out how to prevent hair from turning gray. |
B.Europeans are more likely to gray than Asians and Africans. |
C.Gray hair means poor health or a sign of illness. |
D.Everyone will inevitably get gray hair by retirement age. |
A.Being physically weak. | B.Stress from different sides. |
C.Death of melanocyte cell. | D.Genetic factors. |
A.Make-up | B.Scientific research. | C.Chemical weapon. | D.Cure. |
