Simon James is an super trail runner (越野跑步者) who encourages people to reconnect with nature in the name of exercise. He has completed Super Trail in the Alps, the Andes and the Himalayas. A late night bet with a client got him tied to running.
“In 2006, a business client challenged me one evening in a bar to a 36 hour walk across 54 miles of the West Highland Way, and I foolishly said ‘yes’，” James said. “He then rang me the next day to tell me we would be running it.”
At the time, James was 20 kilograms overweight and the longest he had run before that was just under 8 miles, but he managed to finish that run and has never looked back.
According to a report, two thirds of adults in the UK are overweight, one fifth suffering from depression (抑郁). The huge influence caused by modern lifestyle has worsened these issues. “We are aware of the importance of exercise in everyday life, and no amount of virtual (虚拟的) meetings can make up for direct social contact.” James said, “Only one thing can fix these problems — trail running.”
What is unique about trail running, he explained, is that “it reconnects us to our beautiful nature and connects our physical, mental and spiritual aspects, as well as providing us with an experience which can connect us to other people”.
Inspired, he quit his city life of working 16 hour plus days as a banker, and spent more time in trails and mountains.
James is now in charge of the trail running company Run the Wild. He said every run has been a gift following a physical operation in 2015, even though his doctor told that he could hardly run again. He said, “The outdoors is such a great place for us all to experience.”

A large number of people want to grow their own gardens, but they simply do not have the room. Do not worry. There is a solution. Consider container gardening.
The great thing about container gardening is that you can use a variety of different containers. You simply have to use your imagination. You could create a beautiful garden with things such as cement blocks, hanging baskets, clay pots, or window boxes. There are so many options when it comes to container gardening; it is only limited by your imagination.
Of course, you will want to take the following into consideration when you are ready to begin container gardening, in order for it to be successful.
First, you should avoid any container that has been used to store chemicals, as well as treated wood. This could lead to the sudden death of your flowers and lead to the failure of your container gardening.
With any container that you choose, you need to ensure that it allows the water in it to drain when necessary. So it may be important for you to create holes in the container to help this along. You should also make sure the containers are placed on a raised surface, not upon the floor, to ensure the best possible drainage.
Ensure that the containers you choose are appropriate (合适的) in size for the plants you choose. You need to prevent the roots from overgrowing the container.
If you like fresh veggies, you could consider container gardening with vegetables. This requires a process that differs from that of flower gardening. Talk to an employee at a supply store in your area. They can help you choose the right containers for the vegetables you are wishing to grow.
8．Which of the following may be improper materials for container gardening
A．Cement blocks. B．Treated wood.
C．Window boxes. D．Clay pots.
9．What does the underlined word “drain” in paragraph 5 mean
A．To pick up. B．To give up.
C．To flow away. D．To gain popularity.
10．Compared to flower gardening, what do we know about vegetable gardening
A．It needs special containers.
B．It requires more time.
C．It demands more water.
D．It seems much easier.
11．Who may be interested in the text
A．People who have a big yard.
B．Citizens who enjoy gardening.
C．Farmers who are good at gardening.
D．Children who like outdoor activities.
D
Just as British people are always proud to say that they have “green fingers”， people in the US use about 34 billion liters of water on their gardens almost each day. At the same time, however, much of this country is experiencing a ten years' drought (干旱). People in Florida, California and much of the western United States can't water their lawns — or can't water them as often as they're used to. These lawns may not die, but neither will they look as green as grass lands in other places.
Both homeowners and researchers have been looking for solutions. Brooke Moffis, a graduate student at the University of Florida, works with Basil Iannone in the school's lab on the ecology of living area, aiming to save water. Iannone says one way to do that is to fill a lawn with a variety of native plants. He recommends focusing on ones that can adapt to dry conditions, rather than keeping those thirsty English grasses.
People often regard lawns as grass and nothing else. When a lawn is planted with just one kind, it's called a monoculture (单一栽培). “But we don't need it to be a monoculture to serve the function of a lawn，” Iannone says. Adding native plants, including those that are considered as weeds, can make for a healthier outdoor space, Iannone added.
Imagine you're a hungry insect. If you eat nectar (花蜜) — as many bees, butterflies, beetles, moths, ants and other insects do — a grassy lawn isn't going to feed you. It would be like going to the grocery store and finding only one kind of food for a long time. But it's a food you either can't eat or don't like.
A garden growing a variety of flowering plants would instead seem like a welcome buffet with a variety of food. The different nectar in these many flowers would make sure you and other nearby insects had plenty to choose and eat. That's the idea behind adding flowering plants to existing lawns, such as clover, purslane or pennywort.
12．What is the main idea of the first paragraph
A．Lawns in western California die easily.
B．Americans take good care of their lawns.
C．Some areas in the US lack water for lawns.
D．The British suffer from natural disasters.
13．Why does Iannone disagree on growing English grasses
A．They can't make lawns green.
B．They aren't suitable for research.
C．They can't survive in the United States.
D．They can't grow well without enough water.
14．What do people usually think of lawns
A．Lawns are just made of grass.
B．Lawns show American garden culture.
C．Lawns should include functional plants.
D．Lawns with weeds make healthier space.
15．Why does the author mention buffet in the last paragraph
A．To indicate nectar is good for insects.
B．To introduce different ways to feed insects.
C．To show the benefits of growing various plants.
D．To suggest bringing nearby insects into the lawns.

阅读下面短文，根据其内容写一篇 60 词左右的内容概要。
As most people know, in the past few years, sandstorms have swept across many countries, polluting the air and disturbing daily lives of human beings.Saharan sandstorms have increased about 10 times during the half century since the 1950s, causing topsoil loss in nearby countries.In Mauritania, there were just two sandstorms a year in the early 1960s, but there are 80 a year today.
In desert areas, sandstorms are most commonly caused by either thunderstorm outflows, or by strong pressure gradients which cause an increase in wind speed over a wide area.In some cases, dust and sand may set a limit to a shallow depth by a low lying temperature change.In other cases, dust may be blown as high as 6,100 meters high.Drought is another cause of sandstorms.Poor farming practices make dust and sand free of protection from the wind.Dryland farming is one of the most serious practices.A sandstorm can transport and carry large amounts of sand.Desert is the key source of sandstorms.
Sandstorms have also been shown to increase the spread of disease across the globe.Virus in the dust is blown into the atmosphere by the storms.Some diseases may not be urgent at the very beginning, but they can develop into deadly ones if left untreated.For example, a breathing problem can lead to lung cancer, while dry eyes lead to blindness.
Sandstorms cause soil loss from the dry lands, doing harm to agriculture.Sandstorms also reduce visibility, affecting aeroplanes and road transportation.In addition, sandstorms also discourage visitors from visiting these places, thus striking tourism.
So what should we do with the frightening sandstorms Some experts put forward practical suggestions as follows.For one thing, more funds ought to be put into tree planting and forest protection so as to keep more water resources within the surface of the earth.For another, governments of all countries should make laws on environmental protection.For example, banning the use of throw away chopsticks and punishing illegal tree cutting.Scientists should also study and find ways to cut down the degree of its destruction and to improve the whole environment.
