If you're looking for a reason to care about tree loss, this summer's record-breaking heat waves might be it. Trees can lower summer daytime temperatures by as much as 10 degrees Fahrenheit(华氏度), according to a recent study. But tree cover in US cities is shrinking. A study published last year by the US Forest Service found that we lost 36 million trees annually from urban and rural communities over a five-year period. If we continue on this path, "cities will become warmer, more polluted and generally more unhealthy for inhabitants," said David Nowak, a senior US Forest Service scientist and co-author of the study. Nowak says there are many reasons our tree cover is declining, including hurricanes, tornadoes, fires, insects and disease. But the one reason for tree loss that humans can control is sensible development.
"We see the tree cover being changed, which means when we look at the photographs, what was there is now replaced with a parking lot or a building," Nowak said. "Every time we put a road down, we put a building and we cut a tree or add a tree, it not only affects that site, it affects the region." The study placed a value on tree loss based on trees' role in air pollution removal and energy conservation.
Nowak says there's a downside to trees too, such as pollen allergies or large falling branches in storms, "and people don't like sweeping leaves." But, he says, there are ways cities and counties can manage trees to help communities thrive. Urban forests especially need our help to replace fallen trees. Unlike rural areas, it is very difficult for trees to repopulate themselves in a city environment with so much pavement and asphalt(沥青). "A lot of our native trees can't actually find a place to drop a seed so they can regenerate," explains Greg Levine, co-executive director for Trees Atlanta. "That's why the community has to go in and actually plant a tree because the areas just aren't natural anymore."
Nowak says the first step is caring for the trees on your own property. "We think we pay for our house, and so we must maintain it. But because we don't pay for nature, we don't need to. And that's not necessarily true."

We automatically assume that as adults, we’re wiser than when we were children. However, actually we can learn a lot from our childhood self. For example, we can learn to develop optimism about the future. Do you remember how excited you used to be just before Christmas? 1. Reintroduce that childlike wonder into our daily experiences.
We can learn to dream big and imagine the impossible. How often have you heard a child say something like “One day, I’m going to be an astronaut”? Our adult minds immediately laugh at this idea and think about all the logical reasons as to why this might never happen. 2. We minimize our chances of attaining what we dream about. It is okay to dream big just as our childhood self did.
3. Our childhood self looked at possibilities and believed we could achieve them successfully. If we wanted to build a tree house, we’d go about thinking about how to make it happen instead of focusing on all the reasons it might not happen. In this way we can fill our life with possibilities rather than regrets.
We can learn to be playful and silly sometimes, 4. Children spend a large amount of time escaping from reality to mess about and have fun. Make time for your childhood self to come out and play. Run around the garden, wear a silly hat or spend time laughing. 5..
A.Don’t imagine things could go wrong.
B.We can learn to hold a “can do” attitude.
C.That feeling of great joy is hard to beat.
D.Most children tend to think in a positive way.
E.All of these activities can make us feel happy and alive.
F.We employ self-limiting beliefs without even realizing it.
G.All work and no play makes a person very dull and upset.

Don’t you have time for reading? If you are interested in non-fiction books, here are some good choices for you.
A Room of One’s Own
This essay by English writer Virginia Woolf is based on several lectures given to two women’s colleges at Cambridge University in 1928. In the essay, Woolf describes that it’s circumstance not talent alone, that allows men to be more successful at writing. Women, in other words, spend so much time cooking, cleaning, and tending to their children that they have no time left for art. To write well, therefore, a woman must have a “room of her own”. While on its surface, this essay appears to be only about writing, it is actually about wealth and class, freedom and confinement, and the power struggle between sexes.
The Art of War
Written by ancient Chinese warrior Sun Tzu, The Art of War is widely considered to be one of the best books about military strategies in human history. Consisting of 13 chapters, each dealing with a separate aspect about how to fight a war, the book has been translated into every major language and has thousands of editions. For centuries, it has been used to train world leaders for its detailed study of military strategies and effective leadership.
Letter to My Daughter
This book of essays by Maya Angelou, a respectable African-American poet, is written for “the daughter she never had” — the millions of women, both young and old, that she considers to be her “family”. From the viewpoint of a caring, older relative, this book contains lessons selected from her own life experiences, including the birth of her only child, a son, as well as the development and loss of friendship.
A Brief History of Time
If you’re short of time, then why not read about, well, the creation of time? This book, first published in 1998 from brilliant scientist and mathematician Stephen Hawking, explores mind-bending questions about the creation of the universe, including if and when it will end, and if so, how. Despite its heavy subject matter, Hawking addresses these questions in a way that’s easy to understand, even for those who know little about physics.
1.What can we learn about the four books?
A.A Brief History of Time mainly focuses on the matter of time.
B.Letter to My Daughter is actually a common family letter.
C.The Art of War gives advice on how to be a world leader.
D.A Room of One’s Own is more than about writing.
2.What can be inferred from the passage?
A.As a physicist,Hawking is equally famous in writing.
B.Maya devotes herself to fighting for women’s rights.
C.The book by Sun Tzu is helpful in policy-making.
D.Woolf looks down upon men in writing.
3.What is the purpose of the passage?
A.To make comparisons among the four books.
B.To recommend the four books to readers.
C.To make comments on the four books.
D.To promote sales of the four books.

If you’re looking for a new pet, don’t even think about Komodo dragons, which are the world’s largest lizards and can grow to be 10 feet long and weigh more than 300 pounds. Komodo dragons run fast and eat almost any kind of meat, including dead or live animals, other Komodo dragons and people. “ These things are powerful killing machines,” says Bryan Fry, a biologist.
If those reasons aren’t good enough, consider the bite of a Komodo dragon. According to a new study, it may kill prey like snakes by injecting venom. This chemical, according to Fry and his team of scientists at the University of Melbourne in Australia, can cause shock in the unlucky victim. A person or animal goes into shock when the body cannot offer enough blood to the organs to keep functioning. As a result, the body starts to shut down.
Scientists have only recently begun to understand why a Komodo dragon is so deadly. Some people used to believe that a Komodo dragon’s bite contained bacteria from the mouth that would cause a severe infection in the victim’s blood. The infection would finally kill the animal. Fry says that after being bitten by a Komodo dragon, animals usually die quickly.
After more studies, Fry and his team found that the Komodo dragon venom contained some of the same ingredients as snake venom. These ingredients thin the bolld and cause blood vessels to become larger. To test the venom, the scientists injected rats with it and observed that the rats became still.
Fry’s work show that Komodo dragons kill their prey with venom, and not by bacteria—and gives us another reason why we should avoid coming across them. That is easy to do, since they live only on a few islands in the tropical country of Indonesia.
(no more than 10 words)
1.The underlined word “ venom” in Paragraph 2 probably means _________________.
2.Why does a victim get into shock after being injected?
3.According to Fry and his team, how do the ingredients in Komodo dragons’ venom affect their victims?
4.“If you’re looking for a new pet, don’t even think about Komodo dragons.” What does the author mean by saying that?

If you’re new to San Francisco, paying the city a visit, or simply looking for a new playground for you and your dog, here are four of the finest dog parks in San Francisco.
◆ Corona Heights Dog Park
Often visited by residents from all over the city because of its nearness to the Randall Museum, Corona Heights
Dog Park offers pets and owners breathtaking views, after a steep hillside climb, and a fenced dog area that allows dogs to let loose without a leash（狗链）. Owners will also enjoy the playground, tennis courts and basketball courts.
◆ Dolores Dog Park
The grounds of Dolores Park once served as camps for those who were left homeless by the 1906 earthquake, but now often visited by crowds of Mission District people. Four-legged friends can also wander about carefree off-leash while making friends with other members of the doggie community.
◆ Pine Lake Dog Park
Noteworthy for its place as a rest stop for hundreds of species of birds to fly to and from warmer climates, Pine Lake Park is also prized by city dogs and their owners for their nice hiking paths, picturesque lake suited for swimming, and an off-leash area on the park's west end that lets dogs run free.
◆ Buena Vista Dog Park
At 146 years young, Buena Vista Park is San Francisco’s oldest park. Dogs and owners with plus energy will love burning it on this park’s steep paths and winding staircases. Dog owners should have good control over their dogs, as it’s quite easy for dogs to get separated when going through Buena Vista’s many twists and turns.
1.Why do dog owners take their pets to Dolores Dog Park?

C. To help them lose weight. D. To increase their physical activities.

2.Atlas mountains
The High Atlas is an impressive mountainous range in central Morocco that hosts North Africa's highest peak. Mount Toubkal, at 4,165 meters.

4.Mount Meru
Mount Meru may forever exist in the shadow of its neighbor, Kilimanjaro, but Tanzania's second-highest mountain (4,565 meters) has its own devotees.
It's less known, but Mount Meru is for the true enthusiast who wants to experience what very few people actually do.
Mount Meru is often used by mountaineers to accustom themselves before trying to conquer Kilimanjaro, or by those wanting a hike with the local Massai.

If you’re looking for European culture, there are few better places to visit than Switzerland. Known as the melting pot of Europe, it combines the cultures of Europe with astonishing beauty and fantastic food.
Switzerland’s culture is a combination of neighboring states: France, Germany, and Italy. The result is a multilingual (多语言的) country, as eastern Switzerland speaks French, the southern part speaks Italian and the rest speaks German.
Like the language, the cuisine is also quite different by region. If you visit cities like Geneva, you’ll find traditional French dishes like fondue and raclette, melted Swiss cheese served over bread or potatoes. Meanwhile, in German-speaking regions, like Zurich, you’ll find Rosti, a typical side dish made from fried potatoes.
However, if there’s one thing that unites the Swiss and the rest of the world, it’s their love of chocolate. Swiss chocolate factories are “the most luxurious in the world”, US travel blogger Sarah Schmalbruch wrote on Business Insider. Famous brands, like Lindt, are based in the country. Visitors to Switzerland can enjoy chocolate tasting sessions, and even take classes from master chocolate makers.
Aside from the wide variety of food on offer, Switzerland also offers thrills. The Swiss Alps offer year-round skiing and mountain climbing with local experts. Besides, you can visit the beautiful Matterhorn, known for its distinctive pyramid shape and snow-capped peak. Standing at a height of more than 4, 400 meters, it is the most pictured mountain in the world, according to Smithsonian magazine.
But if city culture is more your thing, you’ll find a wide range of museums and art galleries, not to mention the world’s largest teddy bear museum in Basel.
Even the largest Swiss cities tend to be laid back (悠闲自在的), but with many adrenaline- pumping (肾上腺素激增的) activities and cultural sites, Switzerland is perfect for every taste. After all, where else in Europe offers you the culture of four different countries?
1.The author presents Switzerland as a multi-cultural country by introducing its _________.
A.languages and food B.architecture and food
C.festivals and architecture D.costumes and festivals
2.Why are Sarah Schmalbruch’s words quoted?
A.To show the history of Swiss chocolates.
B.To prove Swiss chocolates are difficult to make.
C.To show how delicious Swiss chocolates are.
D.To stress the popularity of Swiss chocolates.
3.What can you find in Switzerland?
A.The safest skiing location. B.The most pictured mountain.
C.The largest art gallery. D.The oldest teddy bear museum.
4.Where can we most probably read this text?
A.In a geography textbook. B.In a science report.
