There are 115 distinct (独特的) species of pine trees with 35 native to North America. Pines are defined as evergreens with long, needle-like leaves and are only native to the northern hemisphere. Pine trees are an adaptable and tough species that can survive in many conditions where other plants cannot. The average pine tree is 45 to 60 feet tall, but some are nearly twice as high.

Western White Pine

    The western white pine grows the tallest of any pine tree, reaching up to 110 feet in height. They have blue-green needles arranged in bundles (束) of five and produce a long cone (球果).

Bristlecone Pine

    The bristlecone pine grows slowly, reaching about 20 feet tall. It is one of the oldest species of pine.

Mexican Pine

    The Mexican pine can grow to 50 feet tall, with long, slender needles that drape (下垂) off it like a weeping willow (柳树). Often nicknamed the “willow pine”, it is native to Mexico. Its leaves can droop up to 12 inches long.

Sugar Pine

    The sugar pine is another of the large pine species, such as the bull pine, but it also has the largest cones of any pine species, at 10 to 20 inches long. It grows from Oregon to California and is often used for construction.

Jack Pine

    The jack pine is one of the smallest species of pine with rare leaves. Compared with the pines mentioned above, it doesn't seem to belong in the family. It is considered a member of the scrub-pine family; it prefers sandy soil.

    Some of the best thing in life don't happen until you grow old enough to recognize them. I can say that about tea. .

    I didn't start to drink tea until I was 35. The first time felt a genuine urge to drink tea was in 2003, when I stayed briefly in the United Kingdom. After a time of consuming local food, I started to really like strong black tea.

    I took packs of green tea with me as gifts but was disappointed to find my British friends preferred much stronger black tea from Sri Lanka. Later I learned that although people know China for its tea, it ranks only third among the world's black tea exporters, after Sri Lanka and Kenya.

    After I came back to China and started to cover food stories, I met friends in the tea-drinking circle and learned more. Although the majority of the rest of the world drinks black tea, which the Chinese call “red tea”, China processes and drinks mostly green tea.

I feel lucky to be Chinese because of the great variety of tea available in the county. It is estimated that there are more than 2000 tea in China it you divide them geographically,] including more than 600 locally famous tea. A more simple way to categorize it is by color ； and extent of fermentation(发酵). That comes down to six main categories — green, white, yellow, dark greenish(oolong), red and black tea.

    Tasting tea can be compared to our life. It can be plain and predictable but sometimes it is j full of pleasant surprises. Occasionally it can even seem too good to be true. The best thing is, you know there's always more to explore.

    We have a strange obsession with the concept of perfection. “If I have the perfect parents and perfect grades, then I would be happy.” Under cultural influence, we seek what we can't have without remembering that we don't actually need to be perfect. Imperfection allows us to be human.

    Parents, teachers and other high-achieving peers will have us believe that we must be perfect if we wish to remain competitive. However, what job or school requires you to have a 2400 SAT, 4.0 GPA and develop a cure for some form of cancer by the age of 18? Although these would be great achievements, are they worth the cost of sleep? We feel like we need the perfect grades to get into the perfect college that will provide us with the perfect education necessary to obtain the perfect job. With this misconception, when writing our resumes(简历), we then seek out experiences that we think may help build a good name for ourselves. Feeding on our thirst for perfection, some college and career industries have been set up claiming to help us reach our goals.

    The truth is, you only need to be good enough. Don't worry about anything secondary to your passions. You won't become an expert at anything if you spend your time trying to succeed in everything you do. You only become an expert when you devote your time to the one or two projects that truly bring you joy.

    As members of this society, we have a responsibility to be excellent in what we do, not perfect. Although perfection can be a goal, it should not be the only goal. We only have 24 hours in a day. Thus, we need to prioritize(优先选择)what we want to do and cut out the activities we cannot do. If you enjoy debating, take a law class and see how it suits you. If you enjoy cooking, experiment in the kitchen and see what you can make!

    Try as hard as you can and let your future worry about itself. Worry about your task at hand and you will be successful in achieving your dreams. Above all, remember that you are going to be okay.

    Last summer, two nineteenth-century cottages were rescued from remote farm fields in Montana, to be moved to an Art Deco building in San Francisco. The houses were made of wood. These cottages once housed early settlers as they worked the dry Montana soil; now they hold Twitter engineers.

    The cottages could be an example of the industry' s odd love affair with "low technology," a concept associated with the natural world, and with old-school craftsmanship (手艺) that exists long before the Internet era. Low technology is not virtual (虚拟的) —so, to take advantage of it, Internet companies have had to get creative. The rescued wood cottages, fitted by hand in the late eighteen-hundreds, are an obvious example, but Twitter's designs lie on the extreme end. Other companies are using a broader interpretation (阐释) of low technology that focuses on nature.

    Amazon is building three glass spheres filled with trees, so that employees can "work and socialize in a more natural, park-like setting." At Google's office, an entire floor is carpeted in glass. Facebook's second Menlo Park campus will have a rooftop park with a walking trail.

    Olle Lundberg, the founder of Lundberg Design, has worked with many tech companies over the years. "We have lost the connection to the maker in our lives, and our tech engineers are the ones who feel impoverished (贫乏的) , because they're surrounded by the digital world," he says. "They're looking for a way to regain their individual identity, and we've found that introducing real crafts is one way to do that."

    This craft based theory is rooted in history, William Morris, the English artist and writer, turned back to pre-industrial arts in the eighteen-sixties, just after the Industrial Revolution. The Arts and Crafts movement defined itself against machines. "Without creative human occupation, people became disconnected from life," Morris said.

    Research has shown that natural environments can restore(恢复) our mental capacities. In Japan, patients are encouraged to "forest-bathe," taking walks through woods to lower their blood pressure.

    These health benefits apply to the workplace as well. Rachel Kaplvin, a professor of environmental psychology, has spent years researching the restorative effects of natural environment. Her research found that workers with access to nature at the office—even simple views of trees and flowers—felt their jobs were less stressful and more satisfying. If low-tech offices can potentially nourish the brains and improve the mental health of employees then, fine, bring on the cottages.

    It has taken an extremely long time－161 years－but the National Portrait Gallery finally has the Duke(公爵)of Wellington in its collection after a fundraising campaign reached its ￡1. 3m target.

    The gallery announced on Thursday that it had acquired Sir Thomas Lawrence's unfinished final painting of a man regarded as Britain's greatest soldier after a successful appeal.

    Nicholas Cullinan, the gallery's director, said the NPG had been looking for a suitable painting of the Duke of Wellington since the gallery was founded in 1856.

    He called it "a remarkable painting", while Lucy Peltz, the gallery's senior manager of 18th­century paintings, said the work was "an inspiring and powerful image of one of the most influential men of the 18th and 19th centuries".

    The NPG announced last November that it needed to raise ￡300,000, the final piece of a funding jigsaw(拼图). The Art Fund had already contributed ￡350,000 and the appeal reached its target thanks to ￡200,000 from the G&K Boyes charitable trust and ￡180,000 from the National Heritage Memorial Fund. A further ￡570,000 came from a public appeal and the gallery's own funds.

    It was painted in 1829 when Wellington was prime minister, however, Lawrence died in 1830 leaving the portrait unfinished. The gallery believes it is a more attractive work because of that, with the viewer focusing more on the man himself rather than any clothes of power.

    Dan Snow, the historian and broadcaster, said Wellington was a "Titanic figure" in British history, the only field greatest prime minister, a man of genius on and off the battlefield. He added:" This arresting portrait must sit in the national collection and now, following an outpouring of donation, it will do. The artist has caught the Duke's legendary features. Among his many contributions to British life he formed the culture of unbending spirit in the face of difficulty."

    The painting was lent to the NPG in 2015 for an exhibition marking the Battle of Waterloo.
