Scientists are working to develop crop plants that can reduce the amount of water used for agriculture. Almost sixty percent of the world’s freshwater withdrawals from rivers, lakes and other water resources go toward irrigating fields.
Scientists are using biotechnology as well as traditional breeding methods to develop water-saving crops to feed a growing world.
Thomas “Tommy” Carter is a plant scientist in North Carolina. He works for the Agricultural Research Service in the United States Department of Agriculture. He leads Team Drought, a group of researchers at five universities. They have been using conventional breeding methods to develop and test soybeans that can grow well under dry conditions.
Tommy Carter started working on drought-resistant soybeans in 1981. His research has taken him as far as China, where soybeans have been grown for thousands of years.
Farmers in the United States, however, have grown soybeans for only about a century. Tommy Carter says the soybeans they grow are for the most part genetically similar. More differences could better protect crops against climate changes that can reduce production. Those changes include water shortages which could increase from global warming.
The Agriculture Department has a soybean germplasm(胚质) collection, a collection of genetic material passed from one generation to the next. Members of Team Drought studied more than 2,500 examples from the collection.
They looked at ones from the home of soybeans, Asia. They searched for germplasms that could keep plants from weakening and wilting (凋谢)during hot, dry summers in the United States.
Tommy Carter says they found only five. But these slow-wilting lines, he says, produce four to eight bushels（英斗）more than normal soybeans under drought conditions. The yield depends on location and environment.
Scientists are also working on other plants that either use less water or use it better, or both. For example, companies like Monsanto, DuPont and Syngenta have been developing corn with reduced water needs. Monsanto expects to be ready in a few years to market its first corn seeds genetically engineered to resist drought.

I live in north Celebes which is near Philippines. Since early December 2010 most tropical regions have been frequently hit by rain. Just like my hometown, tropical regions only have two seasons, including the dry season that usually starts from April to September and the wet or rainy season which usually happens from October to March. But, it could be indeterminate. Sometimes the rainy season can come a month earlier or later. It can be prolonged(延长) even more than 4 months and so can the dry season. Even during the dry season, rain can occur several times in certain areas.
The prolonged dry season in tropical areas usually causes a lot of losses. It will be very harmful to local farmers, because most of the tropical areas are regions of the developing countries. Sometimes agricultural and plantation crops will be damaged because of so much dry land and the fact that the river used to flow the water for rice fields are also dry. Rain is very important for plants because rain contains many nutrients that plants are in great need of.
What’s more, if the prolonged rainy season arrives and then floods usually occur in certain areas of low lands. Even for the capital city of Jakarta floods have struck several times during the prolonged rainy season. In addition to floods, the rainy season can cause many diseases. During the dry season, diseases are usually caused by mosquitoes such as dengue fever. While in the rainy season, people who have the weak immune will be more easily attacked by some diseases such as flu, fever, diarrhea, and much more.
If you live in the other places and want to travel to the tropical regions, make sure that you have known much about the season and the effect for these months in which you want to travel as tourists. Only in that way, can you at least prepare to deal with tropical weather. How long does the dry season usually last in the author’s hometown?

Still seeking a destination for your weekend break? There are some places which are probably a mere walk away from your college.
King's Art Centre
A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend sees the opening of an exhibition of four local artists.
You could attend a class teaching you how to 'learn from the masters' or get more creative with paint ---- free of charge.
The Centre also runs two life drawing classes for which there is a small fee.
The Botanic Garden
The Garden has over 8,000 plant species; it holds the research and teaching collection of living plants for Cambridge University.
The multi-branched Torch Aloe here is impressive. The African plant produces red flowers above blue-green leaves, and is not one to miss.
Get to the display house to see Dionaea muscipula, a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.
The Garden is also a place for wildlife-enthusiasts. Look for grass snakes in the lake. A snake called 'Hissing Sid' is regularly seen lying in the heat of the warm sun.
Byron's Pool
Many stories surround Lord Byron's time as a student of Cambridge University. Arriving in 1805, he wrote a letter complaining that it was a place of "mess and drunkenness". However, it seems as though Byron did manage to pass the time pleasantly enough. I'm not just talking about the pet bear he kept in his roans. He spent a great deal of time walking in the village.
It is also said that on occasion Byron swam naked by moonlight in the lake, which is now known as Byron's Pool. A couple of miles past Grantchester in the south Cambridgeshire countryside, the pool is surrounded by beautiful circular paths around the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don't trust me, then perhaps you’ll take it from Virginia Woolf- ----over a century after Byron, she reportedly took a trip to swim in the same pool.As mentioned in the passage, there is a small charge for_____.
| A．attending the masters' class | B．working with local artists |
| C．seeing an exhibition | D．learning life drawing |
"Torch Aloe" and "Venus Flytrap" are_____.
| A．common insects | B．wildlife-enthusiasts |
| C．rarely-seen snakes | D．impressive plants |
We can infer from the passage that Byron seemed_____.
| A．to fear pet bears | B．to be a heavy drinker |
| C．to like walking | D．to finish university in 1805 |
What is the passage mainly about?
| A．A way to become creative in art. |
| B．Some places for weekend break |
| C．The colourful life in the countryside. |
| D．Unknown stories of Cambridge University. |
As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.
The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities, others lose heart at the first sign of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "flight or fight" and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Since we can't remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it. People are finding less and less time for relaxing themselves because_____.
| A．they do not know how to enjoy themselves |
| B．they do not believe that relaxation is important for health |
| C．they are travelling fast all the time |
| D．they are becoming busier with their work |
According to the writer ,the most important character for a good manager is his _______.
| A．not fearing stress |
| B．knowing the art of relaxation |
| C．high sense of responsibility |
| D．having control over performance |
Which of the following statements is true?
| A．Stress is always harmful to people |
| B．We can find some ways to avoid stress |
| C．It is easy to change the habit of keeping oneself busy with work. |
| D．Different people can withstand different amounts of stress |
In the last sentence of the passage, "do so " refers to ______.
| A．" expose ourselves to stress" |
| B．"find ways to deal with stress" |
| C．" remove stress from our lives" |
| D．"established links between diseases and stress" |
Forty years ago, Finland was a small, country with mediocre public schools. Today, Finland is still small but no one calls Finland’s public schools mediocre any more.
In 2000, the Finns surprised the world when their 15-year-olds scored at the top of a closely watched international exam called the PISA. Finland has stayed near the top ever since, while the U.S. scores around the middle.
Pasi Sahlberg, an official with Finland’s Ministry of Education and Culture, is in Seattle this week to share the story of Finland’s success, and what states like Washington can learn from it.
Sahlberg’s message, although he is too polite to put it so bluntly: Stop testing so much, trust teachers more; give less homework; shorten the school day.
On Tuesday, in a room filled with teachers, principals, professors, school-board members and policy makers, Sahlberg joked about the Finns’ reputation for being a quiet, humble people. “When Finland hit the top of the PISA,” he said, “the biggest disbelievers were Finns.”
More seriously, Finland never set out to create the world’s top school system. Instead, he said, the country decided in the 1970s that it wanted to ensure that a student’s success didn’t depend on family background.
“Finland relied on cooperation among teachers and schools, rather than on competition. Rather than judging teachers and schools based on test scores,” he said, “Finland puts trust in its teachers and principals. Teachers develop the curriculum in Finland, and design their own tests. There are no national tests, except one at the end of high school.”
That’s just the start. Along with a shorter school day, Finnish students don’t even start school until they are 7 years old. Many primary schools have a policy against giving homework.
“But Finland,” he said, “ succeeded in part by adopting ideas from the U.S. and other countries. And those countries, he said, can learn from Finland, too.”What might be the author’s purpose of writing the passage?
| A．To introduce a Finnish official. |
| B．To compare the education systems of Finland and the US. |
| C．To share the story of Finland’s success in education. |
| D．To ask the US to improve its education. |
People first learned Finland’s success in education from_____.
| A．its students’ performance in an international exam. |
| B．its international exchange prorrams. |
| C．lectures given by Pasi Sahlberg. |
| D．its small-sized public schools. |
Which of the following can contribute to Finland’s success in education?
a. Giving students fewer tests.
b. Giving teachers more trust.
c. Evaluating students’ family backgrounds.
d. Creating the world’s top school system.
e. Starting school late.
| A．a,b,c | B．c,d,e | C．a,b,e | D．b,c,d |
What Pasi Sahlerg said in Paragraph 7 suggested that ______.
| A．children should start school as early as possible. |
| B．competition among teachers might be harmful to education. |
| C．the US education system is still the most advanced. |
| D．it’s necessary to set up a national curriculum. |
Steve Flaig of Grand Rapids, Michigan, knew he’d been adopted as a baby, and when he turned 18, in 2003, he decided he’d try to track down his birth mother. The agency from which he’d been adopted gave him his mother’s name: Christine Tallady. But online searches didn’t turn up any results, and Flaig let it go.
In 2007, though, he searched for the name again online. This time, the search results included a home address near the Lowe’s store where Flaig, then 22, worked as a deliveryman.When he mentioned the coincidence to his boss, his boss said, “ You mean Chris Tallady, who works here?”
Flaig and Tallady, 45, a cashier, had said hi to each other a few times at thestore, but they’d never really talked. He hadn’t even known her name. Flaig thought, “ There’s no possible way she’s my mother.”
For a few months, Flaig avoided Tallady. “ I wasn’t sure how to approach her,” he told a local reporter. Finally, an adoption agency employee volunteered to call Tallady for him.
When Tallady realized that the nice guy she’d been waving at was her son, she blubbered. “ I wasn’t ready to be a mother at that time.” She’d given him up for adoption in 1985, when she was 23. However, she’d always hoped to meet her birth son one day. Later that day, mother and son talked for almost three hours at a nearbybar.
Married with two other children, Tallady said, “I have a complete family now.”What did Steve Flaig do in the Lowe’s store in 2007?
| A．He worked as a deliveryman. |
| B．He was as a cashier. |
| C．He was the boss of the shop. |
| D．He was a local reporter. |
The underlined word “blubbered” in Paragraph 5 probably means______.
| A．shouted aloud | B．read aloud |
| C．said while crying | D．sang happily |
What would be the best title for the passage?
| A．Remarkable Reunion. | B．An Adopted Son. |
| C．A Boss Helped Flaig | D．A Cashier’s Experience |
