While Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven’t just searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone number they once used.
Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.Why was Jennifer watched in an online exam?
| A．To correct her typing mistakes. |
| B．To find her secrets in the room. |

The Sieferts are the kind of environmentally conscious family who has solar panels atop their home. They use timers on their kids' showers and have planted drought-tolerant landscaping. But they feel kind of guilt. “I haven’t thought about the pool as much as I probably should,” said Annette Siefert.
As California's drought worsens, swimming pools have become a target for those who think the classic backyard greens waste water. Some water districts have banned new pools from being filled and have limited how much water existing pools can use.
But some of those agencies are walking back the rules as they make a surprising discovery: Pools aren't the water wasters some have made them out to be. Analyses by various water districts, along with scientific studies, conclude that pools and their surrounding landscapes use about the same amount of water as a lawn(草坪) of the same size. Over time, pools might even use less water. With pool covers, experts say water evaporation(蒸发)can be cut by almost half, making pools significantly less wasteful than grass and about as efficient as drought-tolerant landscaping.
Facing complaints over a recent ban on filling pools, the Santa Margarita Water District conducted its own water-use analysis. It found that pools require thousands of gallons of water to fill initially, but they use about 8,000 gallons less water than a traditional landscape after that. By the third year, the analysis found, the savings add up, and a pool's cumulative water use falls below that of a lawn.
Water agencies such as the Los Angeles Department of Water and Power have come to similar conclusions. Armed with new information, Santa Margarita Water District officials will reconsider their ban next week.
“We want to respect the people's rights to use their property. There are many families we know that have saved for pools,” said Jonathan Volzke, spokesman for the 155,000-customer district. “But at the same time, the reality around us is that we're in the third year of a serious drought, and we don't know if we're in the third year of a three-year drought or the third year of a 10-year drought.”Annette Siefert feels guilty mainly because of ______.
| A．being a typical water waster |
| B．the water-use of their swimming pool |
| C．her control over her kids' showers at home |
| D．the construction of the drought-tolerant landscaping |
According to analyses and scientific studies, a swimming pool ______.
| A．had belter be filled up in the beginning |
| B．becomes more efficient against drought |
| C．isn't what people think to be wasteful of water |
| D．consumes more water than a lawn of the same size |
What does Jonathan Volzke try to express in the last paragraph?
| A．He expects the serious drought to come to an end. |
| B．He thinks highly of those who have saved for pools. |
| C．He appeals for reasonable use of the swimming pools. |
| D．He tries to maintain the right to use the swimming pools. |

A
While growing up in Jersey in the 1960s, I always seemed to be building things. One summer I build a model car with my father. It was a simple affair, and as a capable 12-year-old, I could have easily done it alone. But my father spent the time together with me, and before I knew it, we were both out in the garage, working away.
I wish I had thought about this when I was raising my first son. We never built anything together. Oh, we had a lot of fun, for sure. But we never undertook a common work of our hands.
A few years ago, when Anton, my second son, asked if we could build a treehouse in the big silver maple behind our house, his suggestion immediately reminded me of the memory. Yes, I thought. Of course. My second chance. And so, one day while Anton was in school and I had some free time, I bought some wood. But one thing led to another and we got only as far as the ladder and a simple platform. His vision for the treehouse was not fulfilled that summer, and the three following summers saw me involved with other things. In the middle of our quiet supper last night, I looked at Anton, a high school student now and asked, “Anton, are you still interested in finishing the treehouse?” “Sure, Dad,” he said, and within that “sure” was contained, perhaps, his own self-awareness of a childhood to which he was still attached.
We continued where we had left off. I was surprised at how good a worker Anton had become. Where four years ago all he could really do with confidence was hammer nails, now he was measuring and cutting. In one moment that took my breath away, he attempted to center a support beam(支撑梁)while looking to me for direction. “Is it centered, Dad?” I waved him a little to the right. Then a little more. Then I said. “Perfect.”
And it was perfect. As was this second chance, I finally realized that my father hadn't had to help me build that model car in 1966. He wanted to. And that made all the difference.Not having built anything together with his first son, the author felt _____.
| A．disappointed | B．satisfied |
| C．regretful | D．relieved |
Why didn't they finish building the treehouse at first?
| A．It was too hot those summers. |
| B．Anton wasn't confident enough. |
| C．They gradually lost interest in it. |
| D．They were both occupied with other things. |
From the fourth paragraph, we can see that the father _____.
| A．was proud of his son |
| B．missed the last chance |
| C．felt content with the treehouse |
| D．hoped to finish the work perfectly |
It can be inferred that the author realized _____.
| A．the quiet passing of childhood |
| B．the difficulty in raising children |
| C．the children's dependence on their father |
| D．the significance of undertaking a common work with children |
Imagine a house that keeps itself warm in the wintertime. Think of the savings in terms of fuel bills and unfriendly emissions. Such houses in fact exist, called “passive houses”. The concept of these highly energy-efficient buildings took root in the 1990s, before slowly consolidating as a niche construction (生态位构建) concept in the 2000s. Are passive houses now actively moving into the mainstream as sustainable buildings?
For Brian Mc Garry, an economics lecturer who built a family house based on passive housing criteria in the Pyrenees this year, the arguments look convincing. As his first full winter in the low energy house draws in, we asked him to keep us informed. Do passive houses work?
I had never heard of a passive house in February 2012, when I purchased a plot of land. Nor did I expect that I would be persuaded to build a pre-constructed, custom-designed house based on energy-efficient passive house criteria. It promised to be easier and quicker to build, cheaper to run, and more comfortable to live in. The objective was to incorporate the fundamental concepts of passive energy management into my project: an airtight and highly insulated building envelope; large south facing double or triple-glazed windows (if possible, filled with argon gas) that passively capture the energy of the sun; a heat recovery ventilation system to provide fresh air; and a simple, low-cost heating system consisting of a modern wood-burning stove, a bathroom heater and a portable radiator backup for when the sun doesn’t shine and temperatures decline. No significant limitations were placed on the design, and it had excellent environmental credentials. Moreover, the cost was no more than a conventional build.
After six months in use, the house is proving to be both cheap to run and remarkably comfortable–staying cool in the hot summer was effortless, as long as the windows were shuttered or shaded from the sun. Nowstaying warm in the cold, high-altitude December climate also seems easy, so far.
Winter arrived in force in the Pyrenees in November, with abundant snowfalls and temperatures as low as minus 8° Celsius. Though early days, the house has responded well: the stove is lit during cold evenings but the portable radiator has not yet been needed. This type of construction seems not only to make economic and environmental sense, but to enhance our quality of life, too.We can learn from Paragraph one that passive houses __________.
| A．consume extra energy to keep warm in winter and cool in summer |
| B．had been introduced for a decade before the birth of the theory |
| C．appeal to both the self-builders and those constructors |

| A．using south-facing windows to take in solar energy |
| B．Providing energy for taking a shower when it’s rainy |
| C．supplying fresh air with a special heat recovery system |
| D．placing more demands and restrictions on the design |
How did Brian McGarry find his self-built passive house?
| A．very unaffordable |
| B．Energy-consuming |
| C．comfortable to live in |
| D．Awkward to use |
What is the writer’s attitude towards the passive housing?
| A．supportive | B．critical |
| C．oppositive | D．doubtful |
A man may usually be known by the books he reads as well as by the company he keeps; for there is a companionship of books as well as of men; and one should always live in the best company, whether it be of books or of men.
A good book may be among the best of friends. It is the same today that it always was, and it will never change. It is the most patient and cheerful of companions. It does not turn its back upon us in times of adversity or distress. It always receives us with the same kindness; amusing and instructing us in youth, and comforting and consoling us in age.
Men often discover their affinity (密切关系) to each other by the mutual love they have for a book just as two persons sometimes discover a friend by the admiration which both entertain for a third. There is an old proverb, “Love me, love my dog.” But there is more wisdom in this: “Love me, love my book.” The book is a truer and higher bond of union. Men can think, feel, and sympathize with each other through their favorite author. They live in him together, and he in them.
A good book is often the best urn(瓮) of a life enshrining the best that life could think out; for the world ofa man’s life is, for the most part, but the world of his thoughts. Thus the best books are treasuries of good words, the golden thoughts, which, if remembered and cherished, become our constant companions andcomforters.
Books possess an essence of immortality. They are by far the most lasting products of human effort.
Temples and statues decay, but books survive. Time is of no account with great thoughts, which are as fresh today as when they first passed through their author’s minds, ages ago. What was then said and thought still speaks to us as vividly as ever from the printed page. The only effects of time have been to filter out the bad products; for nothing in literature can long survive but what is really good.
A good book may be among the best of friends because_____.
| A．it changes over the past of time |
| B．it contains all kinds of knowledge |
| C．it doesn’t betray us when we are in trouble |
| D．it comforts us in youth and instructs us in age |
“Love me, love my book” in paragraph 3 probably means _______?
| A．If you love me, you must reading books. |
| B．The book can be a bond between friends. |
| C．I love books as much I love friends. |
| D．If you love the author, you will love his books. |
Which of the following is TRUE according to the passage?
| A．Time can tell whether a literature is good or bad. |
| B．All books are our constant companions and comforters. |
| C．Temples, statues and books cannot stand the test of time. |
| D．The world of a man’s thoughts is what his life is all about. |
The best title for this passage can be.
| A．Reading Books |
| B．A Good Book |
| C．Our Best Friend |
| D．Companionship of Books |
For high school leavers starting out in the working world, it is very important to learn particular skills and practice how to behave in an interview or how to find an internship (实习). In some countries, schools have programs to help students onto the path to work. In the United States, however, such programs are still few and far behind.
Research shows that if high schools provide career-related courses, students are likely to get higher earnings in later years. The students are more likely to stay in school, graduate and go on to higher education.
In Germany, students as young as 13 and 14 are expected to do internships. German companies work with schools to make sure that young people get the education they need for future employment.
But in America, education reform programs focus on how well students do in exams instead of bringing them into contact with the working world. Harvard Education school professor Robert Schwartz has criticized education reformers for trying to place all graduates directly on the four-year college track. Schwartz argued that this approach leaves the country’s most vulnerable(易受影响的)kids with no jobs and no skills.
Schwartz believed that the best career programs encourage kids to go for higher education while also teach them valuable practical skills at high school. James Madison High School in New York, for example ,encourages students to choose classes on career-based courses. The school then helps them gain on-the-job
experience in those fields while they’re still at high school.
However, even for teens whose schools encourage them to connect with work, the job market is daunting. In the US, unemployment rates for 16-to-19-year-olds are above 20 percent for the third summer in a row.
“The risk is that if teenagers miss out on the summer job experience, they will become part of this generation of teens who had trouble in landing a job,” said Michael, a researcher in the US.In the author’s opinion, German high school leavers ______.
| A．enjoy more career-related courses than that of US |
| B．need more career advice from their schools |
| C．perform better in exams than American students |
| D．are less brought into contact with the working world |
According to Robert Schwartz, high school students should _________.
| A．directly carry on higher education |
| B．get contact with the working world |
| C．focus on their performance in exams |
| D．not miss out on the summer job experience |
The underlined word “daunting” in Paragraph 6 most probably mean “______”.

What’s the main idea of the text?
| A．Remarks on recent US high school education reform |
| B．Tips on finding jobs for high school leavers in US. |
| C．The lack of career-based education in US high schools. |
| D．The severe situation of unemployment in US. |
