For a long time in history,numerous scholars have asked the question:what is beauty?As designers update the latest fashions and artists create their masterpieces,what is considered beautiful changes at an alarming pace.Fifty years ago,the full-figured American actress Marilyn Monroe was a symbol of the American aesthetic（美学的）value; today,many Hollywood actresses different in appearance from Marilyn’s have taken her taken per place.However, aesthetic values not only differ from generation to generation,but do so along cultural lines as well.Often,what is considered hating one civilization is just the aesthetic appeal in another.Thus it is difficult to give an absolute definition of beauty.
As fundamental physicists,my colleagues and I like to believe that we are involved in a search for a beauty that affects definition.The beauty that we search for is not what is set up through the work of people and subject to the tastes,but rather what has been laid down by nature Physics allows its students to look past outer appearance,into a deeper beauty.As a human being,I am attracted by the visual appeal of a wave crashing on the beach.As a physicist, however I am able to see the deeper beauty of the physical laws that govern such a phenomenon.
In truth,since Albert Einstein put forward the idea that there might be one main physical theory that governs the universe,aesthetics,have become a driving force in modern physics.Einstein and other later physicists have discovered that:Nature,as its most fundamental level,is beautifully constructed.The extraordinary simplicity of the laws that govern the universes is really breathtaking.As Einstein said, it would seem more likely that we should find ourselves living in a "disorderly world,in no way apprehensible through thinking".Yet we are now closer than ever to a full understanding of the universe's beautiful clockwork.As new discoveries and technologies allow us to examine the physical world on deeper and deeper levels, we find that the beauty itself becomes much deeper.

I began to worry that maybe we had made a mistake when the sand began kicking up and hitting our faces.
That afternoon,my dad had stood on the deck of our home and laughed as our neighbors packed up their cars and headed inland.They left to spend the night in motels or at friends’ homes that were out of range of approaching summer storm.
Challenging the weather that threatened to damping our spirits,we lit a fire on the beach.Dad told jokes and we had a good time.When it was 6:30 pm,all laughter disappeared.Ours eyes were drawn to the sky.A tornado was headed straight for us!In a flash,we were all on our feet.The wind started screaming and now we were running to the cottage.My mom stopped next to the front door."where can we go?"She shouted at my dad.
Most cottages on this part of Lake Michigan had been built without basements.Ours was no exception.The huge windows and the cottage itself wouldn't offer safety from high wind.
"Follow me!"my dad yelled.We crawled beneath the deck,pressing ourselves against the foundation of the cottage.Between the deck supports,we watched the approaching storm in silent terror.
My dad shouted,"Hold on!"and something else I couldn't hear over the screaming wind.I think he was praying. By the time it reached our cottage,it was nothing more than a strong wind.The rest of the storm lasted for an hour and then simply blew away.
1.what did the family do before the storm came ?
A. They left the motels. B. They visited their neighbors.
C. They packed up the cars. D. They stayed on the beach.
2.What was the family do before the storm came?
A. Praying in silent terror. B. Running away at once.
C. Crawling on the ground. D. Closing their eyes tightly
3.Where did the family stay in the storm ?
A. Under a deck. B. In a basement.
C. Inside the car D. Behind a door
4.What can be the best title for the text ?
A. Life on the beach B. An Unusual Cottage
C. Surviving a Storm D. My Admirable Family
Is there link between humans and climate change or not?This question was first studied in the early 1900s.Since then,many scientists have thought that our actions do make a difference.In 1997,the Kyoto Protocol explained our role in the Earth's changing atmosphere and set international limits for gas emissions from 2008 to 2012.Some countries have decided to continue these reductions until 2020.More recently,the Paris Agreement,struck by nearly 200 countries,also aims to limit global warming.But just now how much warmer it will get depends on how deeply countries cut carbon emissions.
This is how much temperatures would rise by 2100 even if nations live up to the initial Paris promises to reduce carbon emissions;this rise could still put coastal cities under water and drive over half of all species to extinction.
To meet this minimum goal,the Agreement requires countries to tighten emissions targets every five years.Even this increase could sink some islands,worsen drought and drive a decline of up to a third in the number of species.
This is the most ambitious goal for temperature rise set by the Paris Agreement,after a push by low-lying island nations like Kiribati,which say limiting temperature rise to 1.5℃ could save them from sinking.
This is how much temperatures have risen since the industrial age began,putting us 40% of the way to the 2℃ point.
The baseline here is average global temperature before the start of the industrial age.
1.It can be concluded from paragraph 1 that .
A. gas emissions have been effectively reduced in developed countries
B. humans have made continuous efforts to slow down global warming
C. the problem of global warming will have been quite solved by 2020
D. the Paris Agreement is more influential than the Kyoto Protocol
2.If nations could only keep the initial promises of the Paris Agreement,what would happen by the year 2100?
A. The human population would increase by one third.
B. Little over 50 % of all species would still exist.
C. Nations would not need to tighten their emissions targets.
D. The Agreement’s minimum goal would not be reached.
3.If those island nations not far above sea level are to survive,the maximum temperature rise,since the start of the industrial age,should be .
A. 0.8℃ B. 1.5℃ C. 2℃ D. 3.5℃

I am writing to suggest lift the ban on using smart phones,tablet computers and other mobile devices in class.
Mobile devices came into existence as result of the development of science and technology.They would benefit us a lot as long as they are used proper.First,mobile devices are efficiency and can help teachers know that students understand what is taught when they finish their exercises.Second,mobile devices can make classes more interested so students will be more willing to learn.Finally,using mobile devices will reduce the use of paper,and which will be good for the environment.Please take my suggestion into consider.
Looking forward to you reply.

Your meeting starts in 10 minutes, but you find yourself1.(stick) in traffic. Don’t panic. With just a press of buttons, your car will lift off the ground and fly to the company. What’s your impression? It seems2.science fiction, but it isn’t. Engineers have taken up the research of flying cars, and they have already found3.(solve) to many of big challenges. They predict that we will be using these4.(amaze) vehicles one day. According to One Car Magazine, one model,5.is part car and part plane, is going to be on the market in the not-so-distant future. It will look like a regular car 6.it’s on the road, but its wings will unfold when the driver7.(decide)to take to the sky. And operated by8.computer, all controls will be automatic(自动的). Imagine this: You’ll be doing your work while your car is getting you to the company9.(safe). And what does this future dream car cost? Well, at first 10.will be about 1 million dollars, but a few years later, you’ll be able to buy one for “only” $60,000. Don’t throw away your old driver’s license just yet!
