Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks' time. Ten inches of rain may be enough for many plants to survive (存活)if the rain is
spread throughout the year, If it falls, within one or two months and the rest of the year is dry, those plants may die and a desert may form.
Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes (沙丘) are formed as winds move the sand across the desert. Bit by bit, the
dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.
There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs (悬崖) and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand , rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing –-very, very slowly ---as these forces of nature continue to work on the rock.
Most deserts have a surprising variety of life. There are plants, animals and insects that :have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.Many plants may survive in deserts when__________________.

EDINBURGH, Scotland (AP) —they arrived before polling stations even opened, dressed for the school day in striped ties and blazers, dress slacks and tartan skirts, book bags over their shoulders —and, for the first time in British history, ballot (选票) cards in hands on September 18.
Scotland’s experiment of allowing more than 109,000 Scottish teenagers aged 16 to 17 took part in the Scottish independence referendum (公民投票), in which Scotland finally decided not to become independent.
The age group only made up a small part of the 4.29 million total voters, but they have “demonstrated how the youngest voters can be some of the most enthusiastic in a mature democracy”, commented The Associated Press. Casting their ballots, they were “proud and passionate” to help their nation decide whether to break away from the UK after 307 years in union.
At age 16, Scottish residents are allowed to join the military, get married, and work. Eighteen is the legal drinking age, as well as the UK’s voting age. But in 2013, Scottish law was changed to allow 16- and 17-year-olds in Scotland to vote in the referendum. The government pushed for the change because “younger voters are more likely to vote with their hearts, not their heads—and embrace fundamental change by voting for the pro-independence Yes Scotland campaign”, NBC News said.
But when the decision was handed down, some worried that high school students might not be as informed as adult voters. However, many experts said that assumption was wrong.
Professor Jan Eichhorn of the University of Edinburgh insisted that Scottish teenagers were as likely to read newspaper articles and campaign materials as their parents. They would simply get these resources through social media.
“There’s no evidence to suggest that they’re less capable than adults of voting, from a research point of view,” Eichhorn told NPR.
Scotland’s move to let younger teenagers vote in the referendum has led to a discussion about whether the voting age ought to be lowered to 16, both in the UK and the US.
“By 16, most people have about as stable an ideology (思想意识) as they are going to get,” Professor Jason Brennan of Georgetown University wrote for CNN, arguing that the US should also think about allowing younger US citizens to vote.The Scottish independence referendum was held on Sept. 18 ______.
| A．to encourage youngsters to be concerned with politics |
| B．to lower the minimum voting age to 16 for the referendum |
| C．to decide whether Scotland would become independent from the UK |
| D．to elect who would be the new leader of Scotland |
According to the passage, we can learn ______.
| A．Scotland gained its independence from the UK eventually. |
| B．It is possible for the USA to lower the voting age to 16 in the future. |
| C．All the people in Scotland thought highly of the government’s decision to lower the voting age to 16. |
| D．Scottish teenagers aged 16 are allowed to join the military, get married, work and drink alcohol now. |
What does the underlined word “embrace” (in para.4) probably mean?
| A．Admit to | B．Object to |
| C．Know about | D．Approve of |
What is Jan Eichhorn’s opinion of the Scottish teenagers aged 16 to 17?
| A．They are as informed and capable as adults of voting. |
| B．They make no difference to the voting result. |
| C．They are too enthusiastic to make informed decisions. |
| D．They are unwilling to be involved in the decision of the country’s future. |
If you go to Ethiopia, you’ll find a strange palm-like structure, which is called WarkaWater. It gathers water from fog and condensation（水珠）and is invented by an Italian firm.
When Italian designer Arturo Vittori and Swiss architect Andreas Vogler first visited Ethiopia in 2012, they were shocked to see women and children forced to walk miles to access what, for them, had always been within easy reach, water.
Only 34 percent of Ethiopians have access to a reliable water supply. Some travel for up to six hours a day to fetch some or, even worse, has to use pond water polluted by human waste, subject to the spread of disease.
Worldwide, about 768 million people—two and a half times the U.S. population—don’t have access to safe drinking water. So just imagine if we could just pull water out of thin air? That’s what Vittori and Vogler asked once they saw the severe problem and promised to take action. Their firm, Architecture and Vision, has since come up with WarkaWater, a grand palm-like structure that may look like something you’d see in a modern art museum, but it’s been designed to harvest water from the air.
WarkaWater, which is named after an Ethiopian fig tree, is composed of a 30-foot bamboo frame containing a fog-harvesting nylon net that can catch water easily, can be easily lowered for repairs and allow communities to measure the water level. Collecting water through condensation is hardly a new technique, but the creators of WarkaWater say their tree-inspired design is more effective, maximizing surface and perfecting every angle to produce up to 26 gallons of drinkable water a day—enough for a family of seven.
Western organizations have been working to provide clean water access in Africa for decades, so WarkaWater joins a very long list of earlier attempts. So far, high-tech solutions, like the once promising Playpump, have failed, mostly due to high costs and maintenance issues.
This is where WarkaWater stands apart—a lower-tech solution that is easy to repair and far more affordable than digging wells in the rocky Ethiopian plateau.What does the underlined phrase “subject to” in the third paragraph most probably mean?
| A．Owing to | B．Opposite to |
| C．Sensitive to | D．Giving rise to |
WarkaWater is designed mainly to ______.
| A．gather clean water efficiently |
| B．reduce water supply costs |
| C．simplify maintenance |
| D．preserve water supplies |
According to Paragraph 6, what caused Playpump to fail?
| A．Lack of advanced technology |
| B．Unsuccessful designs |
| C．Lack of money and maintenance issues |
| D．Unreasonable structures |
Marianne Hardwick was timid and unadventurous, her energy consumed by physical activity and longing, her intelligence by indecisiveness, but this had less to do with the inborn characteristics of her weaker sex ( as her father, Creighton Montgomery, called it) than with the enfeebling(使人衰弱的) circumstances of her upbringing. Creighton Montgomery had enough money to mould (塑造) his daughters according to his misconceptions that girls were not meant to fend for themselves so he protected them from life. What is to say is that Marianne Montgomery grew up without making any vital choices for herself. Prevented from acquiring the habits of freedom and strength of character which grow from decision-making, very rich girls, whose parents have the means to protect them in such a crippling fashion, are the last representatives of Victorian womanhood. Though they may have the boldest manners and most up-to-date ideas, they share their great grandmothers’ humble dependence.
Most parents these days have to rely on their force of personality and whatever love and respect they can inspire to exert any influence over their children at all, but there is still an awful lot of parental authority that big money can buy. Multi- millionaires have more of everything than ordinary people, including more parent power, and their sons and daughters have about as much opportunity to develop according to their own inclinations(意向) as they would have had in the age of absolute monarchy (君主专制) .
The rich still have families. The great divide between the generations is the state of the lower and middle classes, whose children begin to drift away as soon as they are old enough to go to school. The parents cannot control the school, and have even less say as to what company and ideas the child will be exposed to; nor can they isolate him from the public mood, the spirit of the age. It is an often heard complaint of the middle-class mother, for instance, that she must let her children watch television for hours on end every day if she is to steal any time for herself. The rich have no such problems; they can keep their offspring busy from morning to night without being near them for a minute more than they choose to be, and can exercise almost total control over their environment.
As for schooling, they can handpick tutors with sound views to come to the children, who may never leave the grounds their parents own, in town, in the country, by the sea, unless for an exceptionally secure boarding school or a well- chaperoned (伴护着的) trip abroad. It would have been easier for little Marianne Montgomery to go to Cairo than to the nearest newsstand.The author implies that Marianne Hardwick’s timidity were closely associated with ______.
| A．the inborn characteristics of the weaker sex |
| B．the conditions where she was brought up |
| C．the consumption of her energy |
| D．her physical activity and longing |
Which of the following is true according to the passage?
| A．Rich girls always share their ideas with their grandmothers. |
| B．Wealthy children learn at home instead of going to school. |
| C．Middle-class mothers usually steal time for their children. |
| D．Rich parents may have more control over their children than the middle-class parents do |
What can we know about Creighton Montgomery's daughters from the passage?
| A．They did not have up-to-date ideas. |
| B．They were unintelligent. |
| C．They did not have much freedom. |
| D．They had no physical activity. |
It can be learned from the passage that multimillionaires’ children have ______.
| A．little opportunity to develop according to their own inclinations |
| B．absolute opportunity to develop according to their own inclinations |
| C．more opportunity to develop according to their own inclinations than ordinary children |
| D．as much opportunity to develop according to their own inclinations as ordinary children |
What is the main idea of this passage?
| A．The rich control their children's lives without being near them. |
| B．The generation gap only occurs in the lower and middle classes. |
| C．Rich parents have more authority over their children than poor parents. |
| D．Rich girls who are being overprotected by their parents are rather dependent. |
You may not pay much attention to your daily elevator ride. Many of us use a lift several times during the day without really thinking about it. But Lee Gray, PhD, of the University of North Carolina, US, has made it his business to examine this overlooked form of public transport. He is known as the “Elevator Guy”.
“The lift becomes this interesting social space where etiquette (礼仪) is sort of odd,” Gray told the BBC. “They are socially very interesting but often very awkward places.”
We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, liftusers unthinkingly go through a set pattern of movements. He told the BBC what he had observed.
He explained that when you are the only one inside a lift, you can do whatever you want – it’s your own little box.
If there are two of you, you go into different corners, standing diagonally (对角线地) across from each other to create distance.
When a third person enters, you will unconsciously form a triangle. And when there is a fourth person it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle.
New entrants(新进入者) to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple – look down, or look at your phone.
Why are we so awkward in lifts?
“You don’t have enough space,” Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. “Usually when we meet other people we have about an arm’s length of distance between us. And that’s not possible in most elevators.”
In such a small, enclosed space it becomes very important to act in a way that cannot be construed (理解) as threatening or odd. “The easiest way to do this is to avoid eye contact,” she said.The main purpose of the article is to______.
| A．remind us to enjoy ourselves in the elevator |
| B．tell us some unwritten rules of elevator etiquette |
| C．share an interesting but awkward elevator ride |
| D．analyze what makes people feel awkward in an elevator |
According to Gray, when people enter an elevator, they usually _____.
| A．turn around and greet one another |
| B．look around or examine their phone |
| C．make eye contact with those in the elevator |
| D．try to keep a distance from other people |
Which of the following describes how people usually stand when there are at least
two people in an elevator?
The underlined phrase “size up” in Paragraph 7 is closest in meaning to _____.
| A．judge | B．ignore |
| C．put up with | D．make the best of |
According to the article, people feel awkward in lifts because of _____.
| A．someone’s odd behaviors |
| B．the lack of space |
| C．their unfamiliarity with one another |
| D．their eye contact with one another |
The National Trust in Britain plays an increasingly important part in the preservation for public enjoyment of the best that is left unspoiled of the British countryside. Although the Trust has received practical and moral support from the Government, it is not a rich government department. It is a voluntary association of people who care for the unspoiled countryside and historic buildings of Britain. It is a charity which depends for its existence on voluntary support from members of the public. Its primary duty is to protect places of great natural beauty and places of historical interest.
The attention of the public was the first drawn to the dangers threatening the great old houses and the castles of Britain by the death of the Lord Lothian, who left his great seventeenth-century house to the Trust together with the 4500-acre park and estate surrounding it. This gift attracted wide publicity and started the Trust’s “Country House Scheme”. Under this scheme, with the help of the Government and the general public, the Trust has been able to save and make accessible to the public about 150 of these old houses. Last year, about 1.75 million people paid to visit these historic houses, usually at a very small charge.
In addition to country houses and open spaces, the Trust now owns some examples of ancient wind and water mills, nature reserves, 540 farms and nearly 2500 cottages or small village houses, as well as some complete villages. In these villages no one is allowed to build, develop or disturb the old village environment in any way and all the houses are maintained in their original 16th century style. Over 4,000 acres of coastline, woodland, and hill country are protected by the Trust and no development or disturbances of any kind are permitted. The public has free access to these areas and is only asked to respect the peace, beauty and wildlife.
Over the past 80 years the Trust has become a big and important organization and an essential and respected part of national life. It helps to preserve all that is of great natural beauty and of historical significance not only for future generations of Britons but also for the millions of tourists who each year invade Britain in search of a great historic and cultural heritage.The National Trust is a ______.
| A．government agency depending on voluntary services |

| A．preserving the best public enjoyment |
| B．providing the public with free access to historic buildings |
