19.U.S.President Barack Obama said Friday on campaign trail he can make the case for a second term,and voters will come to see him as the candidate best prepared to serve as president by next year's elections,according to an interview he gave to the U.S.media.
In an exclusive interview he gave the Associated Press,Obama acknowledged that the state of the economy could be his biggest hurdle to clear in winning  reelection.
"I think the economy's going to continue to improve,and I think I'm going to be able to make an effective case that…I am the person who is best prepared to finish the job so that we are on track to succeed in the 21st century,"Obama said in the video interview conducted in Chicago,where he attended fund-raising events the previous night.
"I think I can make that case,and I think that,in the debates that take place over the next 18 months,the American people will feel that I deserve a second term,"he said.
Chicago is Obama's home,and the president's reelection campaign headquarters is also located there.He made the reelection announcement on April 4.According to a Gallup poll released on Friday,Obama's approval rating stood at 41 percent,an all time low.Gallup said the figure was fueled by economic dissatisfaction.

6.In the United States,30 percent of the people have a"weight problem".To many people the cause is obvious (明显的):they eat too much.But scientific evidence (证据) does little to support this idea.Going back to America of 1910,we find that people were thinner than today,yet they ate more food.In those days people worked harder physically,walked more,used machines much less,and didn't watch television.
Several modern studies,moreover,have shown that fatter people don't eat more on average than thinner people.A 1979 study of 3,545 London office workers showed that fat people eat less than slim (苗条的) people.
Studies also show that slim people are more active than fat people.A study by a research group at Stanford University found the following interesting facts:
The more the man ran,the greater loss of the body fat.
The more they ran,the greater increase in food intake.
Thus,those who ran the most ate the most,yet lost the greatest amount of body fat.

16.Life for Ron and Joanne Wickham used to be full of soccer games,birthday parties,school plays,and parent-teacher conferences.For most of the past 20 years,they spent their evenings reminding their children to do homework and helping them complete it.Now the evenings are empty except for TV,and the weekends seem to last forever.The children whose activities used to fill their time have moved away and have left empty spaces.The Wickham parents have what is usually called Empty-Nests Syndrome.
Ron and Joanne both work for the Heritage Insurance Company in Ukiah,California.In their mid-50s,they have two children,Anne and Josh.Anne just graduated from California State University-Fullerton and is looking for a banking job in the Bay Area.Josh is still a junior at Claremont McKenna College near Los Angeles,but he can only rarely make the 460-mile trip home to visit his parents.Back in Ukiah,Ron and Joanne often feel the house is too big."It doesn't really echo,"says Ron,"but it feels like it should.Where is everybody?"
Empty-nesters everywhere know the feeling.They are entering a new stage of life,but they remain tied to their former stage.They are typically between the ages of 48 and 60-still working,still involved in their communities,still rooted.This means they aren't free to travel for entertainment or to pull up stakes and move elsewhere.Generally,they live in the homes where they raised their children.Their daily routines may still echo their full-nest days,with wake-up times meant for driving kids to school or meals that include the children's favorite foods.Therapists point out that Empty-Nest Syndrome doesn't last forever."Eventually,a so-called empty nest starts to feel normal and new routines develop,"says UCLA psychology professor Jaswant Singh."Most parents complete this journey just fine,but it usually feels pretty lonely."

3.The Israeli farmers who pioneered the revolutionary technology known as drip irrigation weren't trying to solve  one of the world's most urgent problems.They were just trying to survive.They lived in the desert,and they didn't have enough water to grow their crops.
In its simplest form,it was little more than a pipe with holes in it.But behind each hole was a hi-tech dripper that let out just the fight amount of water.Snaked along a row of crops so that the holes were positioned directly above the roots,the pipe could direct each precious drop of water directly to the plants,getting a bigger harvest while using a very small amount of the water.
Over time,the farmers improved upon the technology,perfecting the drippers that regulated the flow of water,and connecting the pipelines to computers that could determine exactly how much water each plant needed and when.
If the global population kept growing,the rest of the world would increasingly resemble their little community in the desert.So they began selling their irrigation systems in other parts of the world,eventually expanding to more than 110countries.Netafirm,the company says it's lifting people out of poverty and conserving water at a time when the importance of doing so has never been clearer.
The mass adoption of drip irrigation won't save the world by itself.To avoid the coming catastrophe,nearly everybody will,in some way,have to do more with less,perhaps through accepting and using other new technologies.Otherwise,it's going to get ugly.

32.Why is drip irrigation called"the revolutionary technology"?C
A.It saves the world all by itself.    
B.It is controlled by computers.
C.It makes irrigation more effective.
D.It provides deserts with water.
33.What does"one of the world's most urgent problems"in Paragraph l refer to?A
A.Lacking water.  B.Lacking labor.    
C.Lacking food.   D.Lacking energy.
34.How does the drip irrigation help farmers with crops?B
A.By drilling holes on the pipes.    
B.By regulating water via drippers.
C.By snaking pipes along the crops.
D.By placing pipes just above roots.
35.Which of the following will be the best slogan for Netafirm to sell the irrigation systems?A
A.Less water;More harvest.    
B.New technology;New world.
C.More grain;Less starvation.
D.Water saving;World surviving.
16.In a time when a dangerous number of people are overweight,many people seem to have forgotten the most important way to keep healthy and slim---exercise.And as a new study carried out on mice in the lab has shown,exercise done early in life can reward you in your adult years.
A team of researchers at the University of California studied the effects of early exercise on adult physical activity,body mass and eating.They found that early-age exercise in mice has positive effects on adult levels of voluntary exercise in addition to reducing body mass.
"These results may have an effect on the importance of regular physical education in elementary and middle schools,"said Theodore Garland,a professor of biology,who led the research project."If kids exercise regularly through their school years,then they may be more likely to exercise as adults,which could have far-reaching positive effects on human health and well-being."
Although the positive effects of early-life exercise lasted for only one week,it is important to note that one week in the life of a mouse is the same as about nine months for humans."Our results suggest that any positive effects of early-life exercise on adult exercise will need to be kept up if they are to be long-lasting."
His team of researchers found,too,that all mice that had access to early exercise were lighter in weight than non-exercised mice.
Garland explained that,in general,exercise will stimulate appetite sooner or later.However,it is possible that certain types of exercise,done for certain periods of time or at certain light levels,might not  stimulate appetite much,if at all,at least in some individuals.
"If we could understand what sorts of exercise these might be,then we might be able to tailor exercise recommendations in a way that would bring the benefits of exercise without increase in appetite,leading to a better chance of weight loss,"he said.

28.How long do the positive effects of early-life exercise last for a mouse?B
A.One day       
B.One week     
C.One month      
D.Nine months
29.Which of the following statements is TRUE according to the article?A
A.More study is needed to better understand the effects of different types of exercise.
B.Early-life exercise has life-long positive effects on people
C.Kids should be encouraged to do exercise as early as possible to ensure physical health.
D.The new study on mice mainly focused on how exercise affects appetite.
30.The underlined word"stimulate"in the last but one paragraph is closest in meaning toB.
A.decline         
B.improve      
C.vary            
D.harm
31.What is the article mainly about?D
A.New ways to fight against being overweight.
B.The positive effects of mice
C.The possible risks of doing exercise
D.The positive effects of early-life exercise.
