Backpacking through Africa, I always carried some food with me 21 I couldn’t find something to eat．
I was 22 through a local market one day when I 23 upon a jar of 24 jam．I could find tins of apple and strawberry in every corner store but this was the first time I had seen peach．I took it．
For the next few weeks, when I was feeling the need for a little 25 , I would carefully 26 the lid and spoon a bit on to a biscuit．Mum, delicious．I didn’t 27 it with anybody．It sat safely in my 28 , taken out on only special 29 ．
One cold and cloudy afternoon, while I was waiting for a local bus, it started to rain．Everybody scattered for 30 and so did I．But I was already wet through so I quickly searched through my pack for some 31 clothes．
In my hurry to 32 further discomfort, I forgot that the jar of jam was 33 in my clothing．One forceful yank（猛拉）and my 34 jar of jam crashed to the concrete ground, smashing into pieces．
I was so sad that I almost cried．And then, in the corner of my eye, I noticed an old woman in rags 35 ．Without hesitating, she bent down and picked up the half of the jar that still looked 36 ．
Still 37 , she stuck two fingers into the jar, scooped out the 38 jam and placed it into her toothless mouth．Carefully, like fish bones, she 39 the pieces of glass．She studied the broken container 40 she was certain that there was nothing left．Then she left．
My bus arrived shortly after and, as we drove off, I wondered if the jam would taste the same to me．

查看习题详情和答案>>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.
1. According to the passage, scientists try to find out how to _______.
A. grow crops with less water
B. increase crop production
C. feed a growing world
D. save the world’s water resource
2. Why did Tommy Carter come to China?
A. He likes traveling.
B. China has a long history.
C. He’s doing research into soybeans.
D. He works for the Agricultural Research Service.
3. What’s inferred from the passage?
A. Climate changes lead to global warming.
B. Water shortages contribute to global warming.
C. Genetically different soybeans need much water to grow.
D. Genetically different soybeans help to fight against damaging climate changes.
4. What do we know about slow-wilting plants talked about in the passage?
A. They yield big profits.
B. They can grow in almost any climate.
C. They seem to be drought-resistant.
D. They need much water for their growth.
