Climate change will increase US wildfires,and the smoky air will cause terrible problems in areas far beyond those burned,reports an environmental group Thursday.

Two-thirds of Americans,or nearly 212 million,lived in states suffering from wildfire smoke three years ago,according to the report by the Natural Resources Defense Council(NRDC).These areas,which had smoke for at least a week,were nearly 50 times greater than those burned directly by fire.

“It affects a much wide area of the United States than people have realized.” says author Kim Knowlton,a Columbia University health professor,adding the smoke can move up to hundreds of miles.She says the smoke contains air pollution and can cause several kinds of diseases.

Texas was hit hardest in 2011,when smoke stayed for at least a week in areas that are home to 25 million people,according to NRDC’s report.Illinois,which recorded no wildfires within its borders,came second with

nearly 12 million people affected by smoke that moved in from elsewhere.The other eight states with the most people in touch with smoky air were,in descending order: Florida,Missouri,Georgia,Louisiana,Michigan,Alabama,Oklahoma and Iowa.

Nearly two dozen states had no wildfires within their borders in 2011,but eight of them still had at least one week of smoky air: Illinois,Missouri，Iowa,Kansas,Nebraska,Indiana,Wisconsin and Ohio.

Only 18 states and the District of Columbia had no people in touch with at least a week of smoke that year,although five of them—Alaska,California,Hawaii,Nevada and Utah—had a large area burned by wildfires.

The problem will only get worse.Knowlton says.Scientific research shows climate is causing higher temperatures and health problems.

As we know, DNA testing is very useful for crime fighting. But now crime fighters could have a new tool at hand. Researchers have developed a cutting-edge (前沿的) technique to identify human hair. Their test is quicker than DNA analysis techniques currently used by the police.

DNA testing is commonly used for identification because DNA is unique to each individual. However, environmental and chemical processes can degrade(降解) DNA, limiting its usefulness over time. Protein (蛋白质) in hair, on the other hand, is more stable than DNA but can also have variations (变异体) that may be unique to the individual.

“Our analysis process can be used universally, ”says Ms. Huang, “One of our samples even included dyed hair and the test was 100 per cent accurate. The test was able to distinguish East Asians, Caucasians and South Asians.”

Dr. Beauchemin says she has got in touch with law enforcement agencies about using the new technology. She is also planning to collect more hair samples and continue her research with a goal of finding where exactly in the world hair sample is from, to look for more races and determine specific age.

“We are in a very similar place with protein-based identification to where DNA testing was during the early days of development,” said chemist Brad Hart. “This method will be a game-changer, and while we’ve made a lot of progress toward improving it, there are steps to go before this new technique is able to reach its full potential.”

1.What’s the main purpose of the text?

A. To analyze crime scenes.

B. To distinguish different races.

C. To show the usefulness of DNA testing.

D. To introduce a new identification method.

2.Which will be the most useful in identifying a person according to Brad Hart?

A. Chemical materials. B. Protein in hair.

C. DNA variations. D. Blood sample.

3.What’s the advantage of the protein-based identification over DNA testing?

A. Stability. B. Popularity.

C. Security. D. Convenience.

4.What can be inferred from the last paragraph of the text?

A. DNA testing will soon reach its full potential.

B. Protein-based identification remains to be improved.

C. Protein-based identification has replaced DNA testing.

D. DNA testing develops as rapidly as protein-based identification.

A handshake is one of the most common ways to greet others, but US President Donald Trump’s unusual method has been put under the microscope lately.

Much like an arm wrestler in a match, the recently-elected leader has a habit of yanking (猛拉) people’s hands toward himself during handshakes. And while a typical handshake is only brief, the one between him and Japanese Prime Minister Shinzo Abe on Feb 10 lasted a full 19 seconds.

Simply having a strong hand is not the explanation here. According to Darren Stanton, a body language expert from the UK, while handshakes are usually an exchange of kindness, Trump uses his as a way to show power and control, regardless of how uncomfortable it makes people. “It is as if to say, ‘Hey, I’m in charge, don’t mess with me,’ ” Stanton told The Independent.

Apart from Trump’s “yank-shake”, there are other ways people display power with their hands. At business talks or political meetings, for example, some people may rotate (旋转) their wrists during handshakes so that their hand ends up on top instead of underneath. Some may squeeze so hard that it leaves the other person’s hand in pain.

According to Stanton, by pulling people into his personal space, Trump is also testing whether they are willing to cooperate with him. “For example, if someone was resistant to being yanked towards him and stood their ground, he would know that he has work to do with them before he got what he wanted,” Stanton told Express.

This is probably why on Feb 13 when Canadian Prime Minister Justin Trudeau visited the White House, all eyes were on how he was going to handle Trump’s handshake. Fortunately, Trudeau managed to avoid the embarrassment by grabbing Trump’s shoulder to stop himself being pulled in. Afterward, some Twitter users wrote that this proved Trudeau’s strong leadership, with one even calling the moment “one of Canada’s greatest victories”.

Vice magazine summed up the exchange between the two leaders as: “... no regular handshake. This was the first shot in a bloodless war.”

1.According to Darren Stanton, Trump uses his “yank-shake” to _____.

a. show his kindness

b. gain control

c. remind people of his status

d. see if people are cooperative

e. get people to lower their guard

A. bcd B. abc

C. ace D. bde

2.The phrase “stood their ground” in Paragraph 5 probably means _____.

A. going ahead B. standing still

C. turning around D. pulling out

3.According to the text, the way Trudeau reacted to Trump’s handshake _____.

A. annoyed Trump B. displayed his power

C. was considered rude D. was likely to start a war

4.What can be concluded from the text?

A. Some people spin their wrists during handshakes to show extra respect.

B. Handshakes are the most preferable way for political leaders to greet others.

C. The way someone shakes another person’s hand can have different meanings.

D. The longer two people shake their hands, the better their relationship is.

Traffic problems are an everyday concern in many cities，including Washington，DC．A growing number of Washingtonians are turning to bicycles to get to and from work．In fact，the number of commuters who use bicycles has doubled in the city since 2007．

Ralph Buehler teaches urban planning at the Virginia Polytechnic Institute and State University，popularly known as Virginia Tech．He has written a book about urban biking，calledCity Cyclin . g．He says there is a reason why urban bike tiding is now becoming more popular．

“Over the last 60 to 70 years，cities in America have adapted to the automobile．”

“Most cities took advantage of the money coming for the interstate highway system，from the federal government， starting in 1956．There was a 90 percent federal match(补贴)so the cities only had to put up 10％．It was very tempting．”

In the years after World War Two，many Americans moved to suburban communities，just outside major cities．They decided to travel great distances to and from work in exchange for a home in the suburbs．Their cars became a symbol of freedom．

But today，many people believe they can save money by living in the city．

Greg Billing is with the Washington Area Bicyclist Association．“When a person makes a change from using a car to using a bike，he／she is saving anywhere between 8 or $9，000 a year．”

Ralph Buehler says governments save money when people use bicycles．“Building bicycling facilities is much cheaper than building and maintaining road facilities or public transport．”

Washington，DC has also taken steps to protect bike riders．It approved a safe passing law and created areas on the road between cars and bikes．

The United States Census Bureau says 4％of the city’s workers ride to work by bike．The only city on the East Coast with more bike commuters is New York．
