A new study in West Africa shows how farm irrigationsystems powered by the sun can pro-duce more food and money for villagers. The study-in Benin found that solar - powered pumpsare effective in 8upplying water, especially during the long dry season.
Sub - Saharan Africa is the part of the world with the least food security. The United Na-tions Food and Agriculture Organization estimates that more"than one biillion of the world' s peo-ple faced hunger last year.Around 265 million of them live'south of the Sahara Desert:  Lack of  rainfallis one oftheir main causes offood shortages..
Jennifer Bumey from Stanford University in Califomia led the study.The research team helped build three solar - powered drip irrigation -(滴灌) ,systems in northem Benin. Between 30 and 35 women used each system to pump water from the ground or a stream.Each woman was responsible for farming her own 120 sqrurre meters of land. They also farmed other land  collectively.
The solar - powered irrigation systems produced an average of nearly two tons of vegetables per montb. During the first year, the women.kept a monthly average of almost rune kilograms of vegetables for home use.They sold the surplus produce at local markets. The eamings greatly increased their ability to buy food during the dry season which can last six to nine months. Peo- ple in the'two villages with the systems were able to eat three to five more servingsof yegetables per day.But making the surplus available at markets also had a wider effect.
The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets. The amount of vegetables eaten in those villages also  increased, though not as much.The researchers note that only four percent of the croplamd in sub - Saharan Africa is irrigated. Using solar power to pump water has higher costs at first. But    the study says it can be more economical in the long term than using fuels like gasoline,  diesel  or kerosene. And solar power is environmentally friendly.
66.Food security in Sub - Saharan Africa is insufficient mainly because of
A.lack of rainfall         B.limitation of farmland
C. a small crop variety   D.little sunlight
67.From the third paragraph we know that _______.
A.water is wasted by using the system
B. the farmers imgate the land together
C. all farmers use irrigation systems in northem Benin

68.The underlined word "surplus" in the 4th paragraph most probably means_______
A.special             B.unnecessary      C.extra      D.abandoned
69.Usinf.solar power to pump water has advantages EXCEPT that
A.solar energy has higher cost at first
B.solar power helps to protect environment
C.solar power helps farmers increase eanungs
D. solar energy can be more economical in the long run
70.What can be the best title for the text?

The African elephant, which is the largest land animal remaining on earth, is of great importance to African ecosystem. Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna (大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat.
It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.

A.Disappearance of African elephants.

Edmonton's Downtown Park is transformed into one huge stage for five days where artists are able to share their talents, and where people are able to celebrate and enjoy themselves. Since its beginning in 1980, the Edmonton Folk Music Festival has been commemorating (纪念)the true feeling of what folk music is all about and that’s the traditional togetherness (友爱)that is felt when people gather to share stories and feelings through song.
This year will be the sixth year when volunteer Riedel will be offering up her time to the festival. “People coming off a busy spring and summer have a moment of relaxation,” Riedel said. “It’s really easy to relax, and it’s great seeing family and friends have fun together.” These families and friends come from all different kinds of musical tastes. People who take pleasure in Blues are there, so are people who love Bluegrass. This festival does its best to develop everyone's musical interests.
With so many years of experience, the festival has become a well-oiled machine, and does whatever it can to make attendees feel as comfortable as possible. There are free water stations throughout the venue (举办地)for people to fill up their travel cups. When people buy food, reusable dishes are given a $2 plate fee, but that is returned when the plate is brought back.
The festival has completely sold out of tickets, and in record time. But with big names such as Van Morrison and Jakob Dylan, it’s easy to see how that was going to happen. There is no parking area during the festival, so using the Park & Ride system or Edmonton Transit is highly recommended. A bike lock-up area is provided and will be available Thursday until Sunday one hour before the gates open until 45 minutes after the gates close.
The Edmonton Folk Music Festival begins on Wednesday, Aug.4 with Van Morrison playing the special donation fund concert, and will finish up on Sunday, Aug.8.
The Edmonton Folk Music Festival is held mainly to _______.

A.gather people with different musical tastes
B.collect old stories of folk music

It was a dark, wet November morning. It seemed like it would take a million years to get to summer again. I thought bears have got it right---- what a perfect idea to sleep through the worst part of the year and wake up when spring comes!
“Want some words of affirmation(肯定)?” a coworker, seeing my mood, kindly suggested. “You don’t think they would cheer you up?”
“Today? No.” I shook my head.
“I used to think so too,” he said, “until I realized the effect my words had on a certain person. Well, it was someone I knew pretty well. I have to say I treated him rather badly.”
“You? But you are always so positive! How did you treat him badly?”
“I told him I did not like anything about him, really. I told him I did not even like his name. In fact, it wasn’t only what I said. I also did pretty bad things to him. When he was hungry, I did not give him the chance to eat proper food. When he felt like doing something fun, I said to him that he was being childish and having fun was not productive (有成果的). And worst of all, when he was sick and needed care, I did not care. I told him to get up and get to work. And when he did, I never told him he did good work. You could say I was ashamed of him,” he said. “I wanted to get rid of him because he just wasn’t good enough for me---but couldn’t.”
“But that was heartless!”
He nodded. “Then one day it all changed. I stood there in front of the bathroom mirror one morning. I saw the dark circles under his eyes, I saw the excess (过量的) weight. I saw the hair that needed cutting. And I saw the eyes that once had looked at the world eagerly. Now they were so sad and tired. And there and then I realized he deserved better. So I told the man I had disliked for so many years that he was a good person after all.”
My jaw (下巴) dropped. I looked at him---full of positive energy, in good shape, always ready to encourage others.
“Wow…”
He winked (眨眼) at me. “So how about having a little positive conversation with the bathroom mirror? The person in there has the greatest effect on you!”

Living and dealing with kids can be a tough job these days, but living and dealing with parents can be even tougher.
If I have learned anything in my 16 years, it is that communication is very important, both when you disagree and when you get along. With any relationship, you need to let other person know how you are feeling. If you are not able to communicate, you drift apart. When you are mad at your parents, or anyone else, not talking to them doesn’t solve anything.
Communication begins with the concerns of another. It means that you can’t just come home from school, go up to your room and ignore everyone. Even if you just say “Hi”, and see how their day was for five minutes, it is better than nothing.
If you looked up the word “communication” in a dictionary, it would say “the exchange of ideas, the conveyance (表达) of information, means of communication such as a letter or a message”. To keep a good relationship, you must keep communication strong. Let people know how you feel, even if it’s just by writing a note.
When dealing with parents, you always have to make them feel good about how they are doing as a parent. If you are trying to make them see something as you see it, tell them that you’ll listen to what they have to say, but ask them politely to listen to you. Yelling or walking away only makes the situation worse.
This is an example: one night, Sophie went to a street party with her friends. She knew she had to be home by midnight after the fireworks, but she didn’t feel she could just ask to go home. That would be rude. After all, they had been nice enough to take her along with them. Needless to say, she was late getting home. Her parents were mad at first, but when Sophie explained why she was late, they weren’t as mad and let the incident go. Communication is the key factor here. If Sophie’s parents had not been willing to listen, Sophie would have been in a lot of trouble.
Communication isn’t a one-way deal: it goes both ways. Just remember: if you get into a situation like Sophie’s, tell the other person how you feel—listening is the key factor to communication.
In the writer’s view, dealing with parents is __________than with children.

A.more difficult B.easier
C.more uninteresting D.more interesting

The main idea of the second paragraph is __________.

A.the importance of friendship
B.to make your feeling known to others
C.the importance of communication
D.the disagreement between generations

The example in this passage proves that __________.

A.Sophie is very polite to her parents
B.Sophie’s parents are willing to listen to her
C.explanation is the best way to solve a problem
D.communication is the solution (解决办法) to misunderstanding

All the following statements are correct except __________.

A.If you don’t agree with others, you’d better let them know
B.It is better to say “Hi”to others than say nothing
C.If you are not able to communicate, walk away
D.Communication is a two-way deal
