阅读理解

    Crown shyness (树冠羞避) is a mysterious natural phenomenon in which the crowns of some tree species do not touch each other, but get separated by a gap clearly seen from ground level. The effect usually occurs between trees of the same species, but has also been observed between trees of different species.

    There are many theories going around, most of which make sense, but no one has been able to prove without the shadow of a doubt why some trees avoid touching each other.

    In his 1955 book Growth Habits of the Eucalypts, Australian forester M. R. Jacobs writes that the growing tips of the trees are sensitive to abrasion (擦伤), which results in crown shyness phenomenon. This theory was also supported by Dr. Miguel Franco. Some experiments have shown that if trees displaying crown shyness are artificially prevented from swaying (摇摆)in the wind and touching each other, they gradually fill up the gaps between them.

    But while the above theory is arguably the most widespread, it's certainly not the only one. Some scientists have suggested that crown shyness is a mechanism to stop the spreading of leaf-eating insects. The gaps mean pests wouldn't be able to reach other trees, so they are the tree's natural defense method.

    One Malaysian scholar studied many trees, but found no traces of abrasions, despite their clear crown shyness. Instead, he suggests that the growing tips of the trees were sensitive to light levels and stopped growing when they got too close to other trees. Plants are able to sense how close they are to other plants and in order to get more light, they give off some chemical to stop other trees from growing too close.

    Whatever the reason, one thing is for sure, plants are more intelligent than people.

(1)、What can we know about crown shyness?
A、It can cause abrasion between trees. B、It only happens between the same species. C、It has been discovered for only half a century. D、No agreement has been reached about its real cause.
(2)、What will happen if trees showing crown shyness are stopped from swaying?
A、The trees will stop growing and even die. B、The gaps between the trees will grow wider. C、The crown shyness phenomenon will disappear. D、The gaps between the trees will remain the same.
(3)、What does the underlined word “mechanism” in paragraph 4 probably mean?
A、Tip. B、Way. C、Theory. D、Plan.
(4)、Which statement might the Malaysian scholar agree with?
A、Trees have special ways to attack others. B、Some insects stop trees growing too close. C、Trees compete with their neighbors for light. D、Trees won't touch each other to avoid diseases.

    Although problems are a part of our lives, it certainly doesn't mean that we let them rule our lives forever. One day or the other, you'll have to stand up and say – problem, I don't want you in my life.

    I really love my job because I enjoy working with small children and like the challenges and awards from the job. I also think my work is important. There was a time when I thought I would never have that sort of career.
    I wasn't an excellent student because I didn't do much schoolwork. In my final term I started thinking what I might do and found I didn't have much to offer. I just accepted that I wasn't the type to have a career.
    I then found myself a job — looking after two little girls. It wasn't too bad at first. But the problems began when I agreed to live in so that I would be there if my boss had to go out for business in the evening. We agreed that if I had to work extra hours one week, she'd give me time off the next. But unfortunately, it didn't often work out. I was getting extremely tired and fed up, because I had too many late nights and early mornings with the children.
    One Sunday, I was in the park with the children, and met Megan who used to go to school with me. I told her about my situation. She suggested that I should do a course and get a qualification(资格证书)if I wanted to work with children. I didn't think I would be accepted because I didn't take many exams in school. She persuaded me to phone the local college and they were really helpful. My experience counted for a lot and I got on a part-time course. I had to leave my job with the family, and got work helping out at a kindergarten.
    Now I've got a full-time job there. I shall always be thankful to Megan. I wish I had known earlier that you could have a career, even if you aren't top of the class at school.

    Liverpool, my hometown, is a special city. It is so unique that in 2004 it became a World Heritage(遗产)Site.

    I recently returned to my home city and my first stop was at a museum on the River Mersey. Blanketed in mist(薄雾),Victorian architecture rose from the banks of the river, responded to the sounds of sea-birds, and appeared unbelievably charming. When I headed toward the centre, I found myself surrounded by buildings that mirror the best palaces of Europe. It is not hard to imagine why, on first seeing the city, most visitors would be overpowered by the beauty of the noble buildings, which are solid signs of Liverpool's history.

    As if to stress its cultural role, Liverpool has more museums and galleries than most cities in Britain. At Walker Art Gallery, I was told that it has the best collections of Victorian paintings in the world, and is the home of modern art in the north of England. However, culture is more than galleries. Liverpool offers many music events. As Britain's No. 1 music city, it has the biggest city music festival in Europe, and its musicians are famous all over the world. Liverpool is also well-known for its football and other sports events. Every year, the Mersey River Festival attracts thousands of visitors, making the city a place of wonder.

    As you would expect from such a city, there are restaurants serving food from around the world. When my trip was about to complete, I chose to rest my legs in Liverpool's famous Philharmonic pub(酒馆). It is a monument to perfection, and a heritage attraction itself.

    Being a World Heritage Site, my home city is certainly a place of “outstanding universal value”. It is a treasure house with plenty of secrets for the world to explore.

    A study based on data gathered by a NASA sensor has revealed China and India, the world's two most populous countries, are primarily responsible for making the Earth greener over the past two decades.

    The study, published on Feb 11 in the journal Natural Sustainability, has found that since 2000 the Earth's green leaf area has increased by over 5 million square kilometers. That's an area equivalent to the total of the Amazon rainforests. "China and India account for one-third of the greening, considering the general idea of land degradation (退化) in populous countries from overexploitation," said Chen Chi from Boston University, lead author of the study.

    The effect mainly comes from ambitious tree-planting programs in China and intensive agriculture in both countries, NASA said in a statement. China is the source of a quarter of the planet's increase in forest area, despite having only 6.6 percent of the world's vegetated (固定植被的)area, according to the study. Forest conservation and expansion programs account for 42 percent of the increase, and another 32 percent come from intensive agriculture of food crops, NASA said. While raising their green leaf areas, China and India have also greatly increased their food production through" multiple cropping" practices, where a field is replanted and crops are harvested several time each year. "Production of grains, vegetable, fruits and more have increased by about 35 to 40 percent since 2000 to feed their large population," NASA said.

    Over the past decades, China has made great efforts to green the land. In 1978, the central government launched a national-level forestation project-the Three North Shelterbelt Forest Program. By the end of 2017, the forest coverage rate among the regions in the project reached 13.57 percent, compared to 5.05 percent 40 years ago. In a greening project, Kubuqi Desert, seventh largest in the country, has seen one-third of its area covered by vegetation during the past three decades thanks to forestation efforts.
