Brooke Martin’s golden retriever(金毛猎犬) Kayla hated being left alone or separated. She would howl, pace, and chew on things. Brooke learned that other people had the same problem with their pets. She wondered: ―What if you could talk to your dog if you were gone?
Working with her father in their garage, the 16-year-old came up with several ideas. Finally, she invented a device that allowed pet owners to video chat with their pets! She calls the device iCPooch. ―The dog doesn’t have to answer the call,explains Brooke. ―It comes up immediately on the screen on their end. It’s a two-way audio and video—you can see and hear each other.With a click of a button you can even send the dog a treat!
Her invention has earned her a spot competing against nine other finalists in a young scientist competition for middle-school students. These finalists, selected based on their short video presentations, are working with mentors over the summer before heading to the final competition in St. Paul, Minn.
After Martin’s video put her among the 10 finalists in the Discovery Education 3M Young Scientist Challenge, she was paired with Delony Langer-Anderson, a product development scientist in 3M’s consumer health care division. ―I just lead her down the product development path,Langer-Anderson told Live Science. This path includes guidance on how to test the potential product, which combines a video chat device that answers immediately on the dog’s end with a dog treat device the owner can remotely activate.
One thing I have thought about a lot is, what happens if while the device is on the floor, what if your dog knocks it over, or scratches the screen? Martin said. She and Langer-Anderson discussed this, and Martin is now testing materials at a local dog shelter by taping them to the dog house floors to see how well they withstand sharp teeth and claws.
The finalists create models they can test, with the guidance from a mentor. Their projects include a fuel cell that transforms cut grass into electricity and an app that rewards drivers for not texting or calling. Langer-Anderson tries to help the students work through the scientific method, testing their hypothesis, in a determined way, ―so the kids don’t get buried in data.she said.

第三部分：阅读理解（共20小题,每小题2分，满分40分）
阅读下面短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项。
It is midnight on September 22, 2012. The sky above Manhattan，New York is filled with a curtain of colorful light. New Yorkers are fascinated by the beautiful aurora (极光). However, their fascination is short-lived.
Within a few seconds, electric bulbs dim and flicker (闪烁), then become unusually bright for a few seconds. Then all the lights go out. Within 90 seconds, the entire eastern half of the US is without power.
Besides the US, Europe, Japan and China are also hit by the same terrible event. It is a violent solar flare (太阳耀斑) ,150 million kilometers away on the surface of the sun.
Science fiction? No. A report funded by NASA and issued by the US National Academy of Sciences in January this year says it could happen.
A massive solar flare is most likely on a spring or autumn night in 2012, according to the report.
Solar flares
are huge explosions on the surface of the sun. In a matter of just a few minutes they heat material to many millions of degrees and release as much energy as a billion megatons (百万吨) of TNT explosives. Solar flares release a stream of charged high-energy particles (粒子). They are called “solar winds”.
If one solar “wind” should hit the Earth’s magnetic shield (磁场), the result could be terrible for humans 。
But there’s no need to run for cover from solar winds. They do not harm life on Earth, they only affect the way we live, especially since we depend so much on modern technology. They can pump extra electricity into power lines and pipelines, causing blackouts and fuel leaks. Solar winds are also known to affect mobile phone operations and may disrupt wireless Internet services.
Moreover, solar winds can prevent normal satellite operations, and disrupt radio commu
nications and navigation systems such as the Global Positioning System.
Auroras are powered by solar wind. This wind blows past the Earth at about 400-700 km per second and creates storms in the Earth’s magnetic environment. In the polar regions these explode into southern or northern polar lights.
The most serious solar storm that hit Earth in history happened in 1859. It caused the failure of telegraph systems in Europe and North America.
So, for humans, the sun is a double-edged sword. Without the sun, there would be no life on Earth. Without the sun, Earth would be a frozen dark ball floating in space. However, on the other hand, the sun can disorder our lives from time to time.
1. What is the main idea of the passage?
A. It introduces to readers the advantages and disadvantages of the sun.
B. It describes a science fiction set in Manhattan on 22 September 2012.
C. It shows readers the way in which solar winds form inside the sun.
D. It explains what solar flares are and their effects on human life.
2. The first two paragraphs are written ____.

C. to describe the power problem around the world
D. to introduce the topic of this passage
3. What can we conclude from the passage?
A. Solar flares will do great harm to those who are using the Internet.
B. Solar flares cannot reach as far as the polar regions.
C. Solar flares are huge explosions that happen inside the sun.
D. But for our reliance on technology, solar flares wouldn’t
affect us so much.
4. Solar winds will likely affect us in the following ways EXCEPT that ____.
A. normal satellite operations will be stopped
B. the lights in the areas affected will go out at the same time
C. people on the streets will be struck to death

Among various programmes, TV talk shows have covered every inch of space on daytime television. And anyone who watches them regularly knows that each one is different in style. But no two shows are more opposite in content, while at the same time standing out above t
he rest, than the Jerry Springer and the Oprah Winfrey shows.
Jerry Springer could easily be considered the king of “r
ubbish talk”. The contents on his show are as surprising as it can be. For example, the show takes the ever-common talk show titles of love, sex, cheating and hate, to a different level. Clearly, the Jerry Springer show is about the dark side of society, yet people are willing to eat up the troubles of other people’s lives.
Like Jerry Springer, Oprah Winfrey takes TV talk show to its top, but Oprah goes in the opposite direction. The show is mainly about the improvement of society and different quality of life. Contents are from teaching your children lessons, managing your workweek, to getting to know your neighbours.
Compared to Oprah, the Jerry Springer show looks like poisonous waste being poured into society. Jerry ends every show with a “final word”. He makes a small speech about the entire ideas of the show. Hopefully, this is the part where most people will learn something very valuable.
Clean as it is, the Oprah is not for everyone. The show’s main viewers are middle-class America
ns. Most of these people have the time, money and ability to deal with life’s tougher problems. Jerry Springer on the other hand, has more of a connection with the young adults of society. There are 18-to-21-year-old whose main troubles in life include love, relationship, sex, money and drug. They are the ones who see some value 
and lessons to be learned through the show’s exploitation.
1.Compared with other TV talk shows, both the Jerry Springer and the Oprah Winfrey are __________.
A. more interesting B. more formal
C. more detailed D. unusually popular
2. Though the social problems Jerry Springer talks about appear unpleasant, people
who watch the shows________.
A. show disbelief in them B. are ready to face up to them
C. remain cold to them D. are willing to get away from them
3. Which of the following is likely to be a topic of the Oprah Winfrey show?
A. A new type of robot. B. National hatred.
C. Family income planning. D. Street accident.
4. We can learn from the passage that the two talk shows________.
A. have become the only ones of its kind
B. exploit the weaknesses in human nature
C. appear at different times of the day
D. attract different people
5. What is the advantage of the Jerry Springer show ?
A. The show exposes the dark sides of society.
B. The show pours poisonous waste into society.
C. Jerry sums up the whole idea of the show.
D. Jerry talks about the improvement of society.
With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark.”
Noah’s Ark is aimed at collecting eggs, embryos（胚胎）, semen （精液）and DNA of endangered animals and storing them in liquid nitrogen（氮）. If certain species should become extinct（灭绝的）, Dr. Duane Kraemer, a professor in Texas A & M’ s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2,000 species of mammals, birds reptiles will become extinct in over 100 years.The panda, native only to China, is in danger of becoming extinct in the next 25 years. 
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transfer（核子移植）of one species to another is not easy, and the lack of available (capable of being used) panda eggs could be a major problem,” Kraemer believes.” They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking sc
ience if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A & M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinciton. I certainly appreciate their effort and there’s a lot we can learn form what they are attempting to do. It’s a research that is very much needed.”
1. The aim of “Noah’s Ark”project is to_______ .
A. make efforts to clone the e
ndangered pandas
B. save endangered animals from dying out
C. collect DNA of endangered animals to study
D. transfer the nuclear of one animal to another

As an effect of the high fuel prices spent on bus transportation, some American schools are changing to a four-day week. That means longer days instead of the traditional Monday through Friday schedule.
Having been approved for three years and beginning in the fall, students in the Maccray school district in Minnesota will be in school from Tuesday to Friday. Each school day will be 65 minutes longer. Officials say the district expects to save about sixty-five thousand dollars a year in transportation costs.
In new Mexico, the first school district changed to a four-day week in 1974 because of the Arab oil boycott(抵制). Now, 17 out of 89 districts use it.
In Custer, South Dakota, students have been going to school four days a week since 1995. Superintendent(主管人)Tim Creal says the change has saved about one million dollars over just the past eight years. He sees other benefits, too. Students get more instructional time, and activities that used to take up class time are now held on non-school days. He says that in the future, the growth of online classes could make it possible to require even fewer days in school. High fuel prices are driving college students to take more online classes.
A four-day school week sounds like a great idea for students and teachers, but working parents may have to pay for child care for that fifth day.
1. According to Tim Creal, what makes it possible to have even fewer days in school?
A. The increasing number of private tutors.
B. The development of teaching methods.
C. The increase in the number of online classes.
D. The growth in the income of Americans.
2. It can be learned from the passage that______
A. students will be in school from Monday to Tuesday.
B. four-day week was first carried out in South Dakota.
C. Maccray will save one million dollars every year.
D. Minnesota state has approved the four-day week plan.
3. The passage is mainly about______
A. some school’s four-day week plan B. districts using a four-day week.
C. how to save on transportation fees. D. expense of school transportation.
