We all know that the normal human daily cycle of activity is of some 7-8 hours' sleep alternating(交替) with some 16-17 hours' wakefulness and that the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified.
　　The question is no mere academic one. The ease, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed（顛倒的） routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts(輪班) are changed every week; a person may work from 12 midnight to 8 a.m. one week, 8 a.m. to 4 p.m. the next, and 4 p.m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another, so that much of his time is spent neither working nor sleeping very efficiently.
　　The only real solution appears to be to hand over the night shift to a number of permanent night workers. An interesting study of the domestic life and health of night-shift workers was carried out by Brown in 1957. She found a high incidence (發(fā)生率) of disturbed sleep and other disorders among those on alternating day and night shifts, but no abnormal occurrence of these phenomena among those on permanent night work.
　　This latter system then appears to be the best long-term policy, but meanwhile something may be done to relieve the pressure of alternate day and night work by selecting those people who can adapt most quickly to the changes of routine. One way of knowing when a person has adapted is by measuring his body temperature. People occupied in normal daytime work will have a high temperature during the hours of wakefulness and a low one at night; when they change to night work the pattern will only gradually go back to match the new routine and the speed with which it does so parallels, broadly speaking, the adaptation of the body as a whole, particularly in terms of performance. Therefore, by taking body temperature at two-hour intervals(間隔時(shí)間) throughout the period of wakefulness, it can be seen how quickly a person can adapt to a reversed routine, and this could be used as a basis for selection. So far, however, such a form of selection does not seem to have been applied in practice.
小題1:The main problem of the round-the-clock working system lies in       .

D．to create better living conditions for night workers

小題3:It is possible to find out if a person has adapted to the changes of routine by measuring his body temperature because       .

A．body temperature is higher when the cycle of sleep and wakefulness alternates

B．body temperature changes when he changes to night shift or back

C．the temperature reverses when the routine is changed

D．people have higher temperatures when they are working efficiently

小題4:Which of the following statements is NOT TRUE?

A．Body temperature may serve as an indication of a worker's performance.

B．The selection of a number of permanent night shift workers has proved to be the best solution to problems of the round-the- clock working system.

D．Disturbed sleep occurs less frequently among those on permanent night or day shifts.

Four out of ten parents in the UK spend between ￡100 and ￡500 on their children’s birthday parties, according to a survey. Four in ten parents of children under 18, who were questioned in a survey, admitted that they felt pressured into organizing more expensive birthday parties for their children than they would like to.
How much parents spend on their children’s birthday parties is one of the most frequently discussed topics on parenting websites. Here is one comment on Mumsnet summing up the thoughts of many parents: “Where we live everyone hires places, entertainers and so on. I don’t want to compare with my rich neighbors, but I want my son to have what all his classmates have.”
The research was carried out on behalf of the children’s charity, Lumos, set up by the author JK Rowling. Just 13 percent of parents spent ￡50 or less in the past year on their children’s parties.
Many children’s clowns(小丑) or entertainers charge ￡150 or more for an hour, and parents often feel it necessary to book a special place. Even without these, the cost of plates, the cake and party bags can mount up. Party Pieces, a company set up by Carole and Michael Middleton, charge about ￡16 for a birthday cake for a party with 16 guests, ￡22 for table decorations and up to ￡48 for party bags.
Many children of famous people have increasingly expensive parties, often seen in famous magazines. Suri Cruise, the daughter of actor Tom Cruise and actress Katie Holmes, enjoyed a ￡100,000 birthday party according to a report.
Georgette Mulheir of Lumos, said,“Parents in the UK are under increasing pressure to spend more and more money on birthday parties for their children and their children’s friends.”
小題1:What’s the main idea of this passage?

A．Children’s birthday parties put their parents under financial pressure in the UK.

B．Many parents are willing to spend more on their children’s birthday parties.

C．Parents pay more and more attention to their children’s birthday parties.

D．Children in the UK hope for more and more expensive birthday parties.

小題2: What does the underlined part “mount up” in Paragraph 4 probably mean?

A few years ago, my younger brother and I went to Norfolk, Virginian by plane.       , before we took off, we heard the pilot’s voice throughout the plane, “sorry, ladies and gentlemen. We have no       on the plane. We have a generator(發(fā)電機(jī)), and we are going to        the engines with it. We will        in the air and head to Norfolk, and see what happens. ”
See what happens? We are going to get up in the air, and see what happens? At this point, one woman started crying. “Oh, no! We are going to       ！” There were sighs of desperation and       spreading throughout the plane, and we hadn’t even        yet. Thirty minutes passed and we were still        there. Then the voice of the pilot came over again,“ Ladies and gentlemen, I know you are       , so we are. We only have one engine going right now, and it is working double time. ”
There was crying       we had walked into grave. But, the pilot told us our one engine was working double time, and his        was to get up in the air and see what happens! Then we did. We got up in the air and         happened. We arrived in Norfolk and everyone        for still being alive.
Although I do sincerely like to have a plan        “see what happens”, which really isn’t such a bad life strategy, all too often, I would see people pursuing their goals        with inaction just because they don’t have        success. Actually, success will never be guaranteed. The       thing that you can do is just get up in the air, and see what hap­pens.
If you are planning to learn a new skill, get up in the air, and see what happens! It might not be as       as you thought. You might be smarter than you thought. It could be        ! So don’t stay there trying nothing just because there is no        of guaran­teed success.

In December 2008, Caroline Kennedy — daughter of the late U.S. President John F. Kennedy—sat down, as a frontrunner for the Senate seat in New York, for a televised interview that helped decide the future of her campaign. The result was a disaster.
Her performance wasn’t well received, in part because her speech was full of filler words—“ums,” “ahs” and “you knows.” One listener counted 27 “ums” and 38 “you knows” in the space of five minutes. A few weeks after the interview, Kennedy ended her Senate campaign.
Filler words may seem natural in everyday speech, but they can be deadly in formal presentations. “Using excessive fillers is the most annoying speech habit,” said Susan Ward, a speech specialist. “They take your listener’s attention away often to the point that he doesn’t hear anything you say. Your message is entirely lost.”
Many speakers are afraid of pause. They believe their audience will think they are inarticulate (不善于表達(dá)) if they pause to think of what to say next, so they use filler words to avoid the silence. However, a pause is actually more impressive than a filler word. Listeners know that the speaker is thinking, trying to find the right word. Sometimes a pause can actually improve a speech, as when an actor uses a dramatic pause to hold the attention of his audience. A speaker shouldn’t be afraid to pause occasionally during a speech; it shows self-confidence.
It takes some work to cut out filler words. You can begin by taking a few seconds to think about what you want to say the next time you are asked a question. This pause will help you begin powerfully, and it will help you avoid using a filler word.
The same public speaking technique applies when you are shifting from one idea to another. While you may be tempted to fill the silence between ideas with a filler word, remember to allow yourself to pause and think about what you want to say next.
If you need help overcoming your “um” problem, consider asking a family member or a friend to point out when you use filler words. You also could record an upcoming presentation and then watch yourself in action. You may be amazed at how often you say “um” or “uh”!
Although we live in a fast-paced society that seemingly demands instant answers, we must use the pause to our advantage. Finally, we should only speak when we are ready.
小題1:In the first two paragraphs of the article the writer intends to ______.

A．introduce Caroline Kennedy to readers

B．illustrate how deadly filler words can be in the public speech

C．explain what filler words are

D．remind readers that they should count filler words used in public speeches

小題2:The reason why filler words are considered annoying by speech specialist is that   ______.

A．they prevent the listener from focusing on what the speaker is saying.

B．they convey the speaker’s superiority to the listener.

D．they make the speaker appear self-confident.

小題3:When used properly, pauses in speeches can actually ______.

A．give the speaker more credibility

B．hold the attention of the audience

C．show the speaker’s deep insight

D．help the audience relax

小題4:Which of the following is NOT suggested as a way to get rid of filler words?

A．To have mental training in order to think faster.

B．To ask someone else to point out when you use filler words.

C．To watch a recording of your own speech.

D．To practice thinking for a moment before answering a question.

The popular US drama series “House of Cards”, which has already started its second season, features Chinese elements in its storyline. Traditional heroes are no longer sought after anymore. Today, it’s unconventional leading figure -like Francis J. Underwood from “House of Cards” who are winning audiences’ hearts.
The political drama, which airs on the Internet service Netflix, has won the applauses of viewers around the world since its debut(首次亮相) on February 1, 2013. And it has caught the attention of real politicians, including US President Barack Obama.
Kevin Spacey plays Francis J. Underwood, a cold-blooded Democrat who moves his way up the political ladder by any means necessary. He often uses his under-exposure in media to carry out misdeeds that will later benefit him.
The revenge(報(bào)仇) theme plays a heavy role throughout the storyline, Underwood, who had high hopes for an appointment as Secretary of State in the first season, was betrayed by the US President and his former colleagues. He and his wife then conducted a plan of revenge and swore to unseat those who turned their backs against him. Through their plan, Underwood’s own hunger for power grew and empowered him to get rid of whoever stood in his Way.
The release of the trailer(預(yù)告片) of the second season excited millions of viewers around the world, including US President Barack Obama, who has been a loyal fan since the series debuted. Obama expressed his admiration for Underwood. “This guy’s getting a lot of stuff done,” he said. Although the President is anxious to watch the story unfold, he’d like to do it at his own pace. After the release of the second season on February 14, 2014, Obama sent words on his Twitter account, “Tomorrow: @HouseOfCards. No spoilers , please.”
The second season has promised to be darker, with more unexpected turnouts, and is to include more Chinese elements. “Perhaps the team, including myself, has realized that in the next decade, Asia will be an extensively important region, and China will play an active role in its transition and change,” says Spacey.

Dealing with conflict in the workplace is rarely easy. Hurt feelings and anger can lead to lower employee morale (士氣) as well as a loss of productivity and a poor work environment. As a manager. you should find some ways yourself to solve the conflict. The goal is to build a team-centered workforce.
You can use role-reversal (角色轉(zhuǎn)換) methods to help each employee understand how the other feels. This model works best when there are only two parties involved. You can hold a meeting with annoyed workers in your office. You might say. "Jane, explain to me how you would feel if Nancy went to lunch with your clients (客戶 ) without telling you?" Or. "Nancy, how would you respond if Jane came to me with complaints about you, but hadn't tried to talk to you about them first? "
Workers often respond better to praise than criticism. By publicly drawing attention to employees who have healthy work relationships. you can increase the awareness for those who encourage any conflict. Avoid mentioning teams or departments that are being troubled by conflict. Instead. focus on the teams that work well together You might say. "I want to express thanks to the design team for working together to meet the deadline this week," or -Special thanks to the finance department for their teamwork in making sure that the quarterly reports were accurate"
And help your employees see that differences can be good and don't necessarily lead to anger or disagreement This is one of the best ways to settle workplace conflicts. You can meet with employees and try to stress the value of different techniques. This lets all parties know that their own styles can be effective. You might say. " I know you disagree on how to market our services. but when you combine Jim's email marketing with Joe's personal one-on-one phone calls, you can increase sales. The two of you go well together. " Or. "I know you have different styles for interacting with clients. but Sally's take-them-out-for-coffee approach works well together with Ann's formal business meeting style Both are necessary for building relationships and getting work done. "
小題1:To build a team-centered workforce, employers_________.

A．should learn to be considerate

Consumer electronics once again topped the list of the most wanted gifts this holiday season. “Seventy-six percent of consumers who plan to buy holiday gifts say that they will spend money buying at least one technology product; definitely a solid vote of confidence for technology.” Steve Koenig is with the Consumer Electronics Association. He says the group’s latest research also shows that Americans this year are spending more on technology products.
“Here in 2012, $252 on average–the technology spend for consumers this year.” From tablet computers to smartphones, American shoppers have been lining up to get the newest and coolest electronic devices on the market. There are more choices today than ever before. “It’s kind of hard to make a decision.”
Tablet computers are one of the best-selling products this year. Brian Tong is Senior Editor of CNET.com. The website reports on tech news and examines the latest electronic products. He says the Apple iPad Mini is one of the most popular tablets. Its starting price is $329. One of Apple’s biggest competitors is the Google Nexus 7. It starts at $199.
“The hardware inside is more powerful than what’s in the iPad Mini, but also it offers you a lot of things like maps that work better than Apple’s maps.” Brian Tong says there is one reason why people may like the iPad Mini more than the Nexus 7. “If you just want to read books and surf the Internet, you don’t really need to get an iPad Mini, but if you want the largest group of apps that’s where the iPad and Apple’s ecosystem shines the most.”
Elman Chacon is with the electronics store Best Buy. He says another hot product this season is smart cameras. They connect to the Internet through Wi-Fi. This makes it easy for users to email or upload photographs directly from the camera. “You can literally take a picture, upload it into your Facebook in a matter of seconds. These things are pretty cool because they do a lot of things.”
Streaming media boxes also connect to the Internet. People are able to watch web content such as movies and YouTube videos on their televisions. Another popular item is wireless speaker systems. The newest ones work with any device that has Bluetooth technology, including smartphones, laptops and tablets.
With the growing popularity of Internet shopping, many consumers will visit a store first to look at a product, and then go online to find it at a lower price. Stores like Best Buy understand that and they want to stay competitive.
“We have something called the perfect match promise which means if you buy a certain device and you find it cheaper within 30 days we’ll go ahead and price match that for you.” Elman Chacon said.           
小題1:According to Brain Tong, ________.

What could be cuter than your puppy giving his doggy friend a kiss on the nose? Nothing, really. But is your dog actual-fly planting a kiss on his friend? Yes, but that’s only one of the reasons your dog may lick another dog’s nose. Here are some other reasons why your dog may lick another dog’s nose.    
During an introduction, a shy and lower-ranking dog will lower his head, avoid direct eye contact and gently extend his tongue to lick the nose of a more confident and high-ranking dog. The first dog licks the nose of the second dog to simply make it know that：he comes in peace.
Dogs who are already friends will also trade kisses. Two strongly bonded dog pals will lick and clean each other. They give each other “dog kisses” showing friendship.
Puppies also “kiss” their mothers, but it's not a gesture of love. When puppies stop suckling(吸吮)their mothers’ tits for milk and start to eat semisolid(半固體)food instead；they lick their mothers’ mouths and noses in the hope of getting the mother to regurgitate(反哺) some semi-digested food.
So how to help your bashful dog make friends with other dogs? You can carefully select confident-but-friendly and good-tempered dogs to play with your shy dog, to help him develop his social skills. Also consider taking him to a special training class that focuses on socialization and positive training technique.
Do not disturb them when your two dogs play “kiss” briefly with each other. Sit back and enjoy this display of friendship. Then call them over and have them do a command such as “sit’’ or “shake paws”. Offer them treats as a reward for being good to each other.
If you foster(收養(yǎng))a dog and have three or more resident dogs, introduce the foster dog to your brood dog one at a time and let muzzle licking between them happen naturally. Start with your least reactive or most friendly dog. Never force an in production between the dogs because this can deepen the foster dog’s submissiveness or spark a fight.
