    You can tell a lot about people by looking at their hair – not just whether they brush, spray or blow-dry. Scientists have found a way to use hair to figure out where a person is from and where that person has been. The finding could help solve crimes, among other useful applications.

    Water is central to the new technique. The liquid makes up more than half an adult human's body weight. Our bodies break water down into hydrogen(氢) and oxygen. Atoms of these two elements end up in our tissues, fingernails, and hair.

    But not all water is the same. Hydrogen and oxygen atoms can vary in how much they weigh. In the case of hydrogen, for example, there are three types according to their weights. Each type is called a hydrogen isotope(同位素). And depending on where you live, tap water contains different isotopes.

    Can hair record this information? That's what James R. Ehleringer, an environmental chemist at the University of Utah, wondered. To find it out, he and his colleagues collected hair from hair stylists in 65 cities across the United States. Even though people drink a lot of bottled water these days, the researchers have found that people's hair has the same isotopes as found in local tap water. That's probably because people usually cook their food with the local water.

    Authorities can now use the information to analyze hair samples from criminals or crime victims and narrow their search for clues. For example, one hair sample used in Ehleringer's study came from a man who had moved from San Francisco to Salt Lake City. As his hair grew, it reflected his change in location.

(1)、What do we know about the hydrogen isotopes according to Paragraph 3?

A、They are classified by size.   B、Each type of them differs in weight. C、They can improve the quality of tap water.    D、Some of them cannot combine with oxygen.
(2)、Why is it possible to know where people are from by analyzing their hair?

A、People use the same bottled water. B、People wash their hair in different ways. C、People's hair is affected by the weather of the places they stay. D、People' hair indicates the type of water in the places they stay.
(3)、The last paragraph is mainly to show _______.

A、how to recognize criminals B、how to collect hair samples C、the usefulness of hair analysis D、the process of Ehleringer's study
(4)、Which of the following can be the best title for the passage?

A、Water composition B、Change your hair C、Hair detectives D、No way out

Their cheery song brightens many a winter's day. But robins are in danger of wearing themselves out by singing too much. Robins are singing all night一as well as during the day, British-based researchers say.
David Dominoni, of Glasgow University, said that light from street lamps, takeaway signs and homes is affecting the birds' biological clocks, leading to them being wide awake when they should be asleep.
Dr Dominoni, who is putting cameras inside nesting boxes to track sleeping patterns, said lack of sleep could put the birds' health at risk. His study shows that when robins are exposed to light at night in the lab, it leads to some genes being active at the wrong time of day. And the more birds are exposed to light, the more active they are at night.
He told people at a conference, "There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing. Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy."
And it is not just robins that are being kept awake by artificial light. Blackbirds and seagulls are also being more nocturnal. Dr Dominoni said, "In Glasgow where I live, gulls are a serious problem. I have people coming to me saying `You are the bird expert. Can you help us kill these gulls?'.During the breeding(繁殖)season, between April and June, they are very active at night and very noisy and people can't sleep."
Although Dr Dominoni has only studied light pollution, other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise.
However, some birds thrive(兴旺)in noisy environments. A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalising on their predators(天敌)fleeing to quieter areas.

    We took a rare family road trip to the Adirondacks in late August,and it was as refreshing and exhausting as family vacations tend to be.Toward the end of our long drive home, even the kids were leaning forward in their seats urging my lead foot on.At that point in a road trip,even sixty-five miles per hour feels slow. We have become numb to our speed and numb to the road signs flashing by.

    My family lives on the edge of Lancaster County. Only thirty miles from home,I hit the brakes,and we began to roll,slowly,behind a horse-drawn carriage. We began to open our eyes again.We saw familiar green hills and the farm with the best watermelons. I rolled down the windows, and we breathed again.Just-cut hay and a barn full of dairy cattle.

    At five miles per hour,you remember what you forget at sixty-five.You are thinking about a place,even when you are moving from place to place.

    I am a placemaker. A homemaker, too. I am a mother of a young kid at home,and also a writer and a gardener.But,for me,those roles are wrapped up with the one big thing I want to do with the rest of my life:I want to cultivate a place and share it with others.

    The place I make with my family is a red-brick farmhouse built in l880. It has quite a few nineteenth-century bedrooms and a few acres of land,and we love nothing more than to fill them with neighbors and friends. We grow vegetables and flowers,keep a baker's dozen of egg—laying chickens,and,since we moved in three years ago,we have planted many,many trees.

    Living with my life's purpose does not allow for much travel. I need to be here,feeding the chickens and watering the tomatoes. Any extra in the budget,and we spend it on trees.

    But I learned something at the end of our family road trip.Travel can help me in the task of caring for my own place.When I slow down and pay attention to the road between here and there,travel tells me the connections between my place and all the other places.

    Science is always advancing over time. A self-driving car from the Google may be coming to a street near you. However, you won't be able to buy it now. “We're working to build the world's most experienced driver,” Kraft, director of the project, said. “Everything that we learn in one of our cars gets passed to all of our cars. But you may need to get over the idea of traditional car ownership along the way.”

    Google's software has already driven 5 million miles in U.S. cities, including an “early rider” test in Phoenix last April. Since then Google has grown confident enough to remove the “auxiliary wheel”: a human “safety driver”. Powering the vehicle's self-driving functions is a series of cameras, radars and sensors on the car's roof, which detect everything nearby from other vehicles and passers-by to cyclists.

    Kraft stressed that Google's cars aren't connected—they don't need a 5G wireless link to go anywhere. “The car has everything it needs to drive on the car itself.” He said, “There are no signals coming from outer space or something telling it to turn right.” The resulting ride may not be too exciting but safe. Kraft added. “We can see three football fields down the road, we would come to a stop before we ran into these crowds.”

    Google's system has a major advantage over the semi-autonomous(半自主的)systems of Tesla and Cadillac, both of which need continued human attention. Kraft said Google plans to have service in every major city by 2028 with thousands of cars driving themselves.

    Here are some recommendations for tourists to choose from.

    Banff, Canada

    Banff, located in the Rockies, has a view of tall mountains, deep valleys and lakes, making it the first town to become part of the country's national parks. Tourists can enjoy its beauty by hiking, horse riding and boat trips. Banff was founded in 1883 while a railroad was in construction. It was the water springs that drew the engineers' attention to the place as a settlement. With such a fantastic view, it's no surprise that Banff hosts a number of cultural festivals.

    Lisbon, Portugal

    Lisbon is the capital of Portugal, with the warmest winters of any major European city.

    Belem Tower and Jeronimos Monastery are listed as UNESCO World Heritage Sites. The former was built in the 16th century as a symbol of Portugal's Extraordinary Age and the latter is one of the greatest examples of the Portuguese late-Gothic style of architecture. The Lisbon Oceanaium is among Europe's finest aquariums. The Museu Calouste Gulbenkian is among the best museums in Europe containing priceless artworks covering 4000 years from ancient Egyptian times to the late 20th century.

    Portland, US

    Portland is frequently recognized as one of the world's most environmentally-friendly cities because of its well-built pavements, large community of cyclists and convenient public transportation. Its climate is ideal for growing roses and it's called the “City of Roses”. Besides, the seaport is also known as a city of beer: it has the largest number of beer breweries(啤酒厂)of any city in the world. Today's Portland is better known for its music. It's called “the capital of karaoke” and “one of the most exciting music scenes” in the US.

    Bordeaux, France

    Bordeaux attracts tourists with its rich cultural heritage, especially its wealth of architectural treasures. Besides the Cathedral of Saint Andrew dating back to 12th century, the Basilica of Saint Michael is another one of the city's UNESCO World Heritage Sites. It took 200 years to build from 14th to 16th centuries. Other significant buildings include the Grand Theater built in 1780 in the new Classical style and the Stone Bridge built in 1821.
