Dogs can be trained to identify the smell of lung cancer long before symptoms develop.
A new study is the first to show that sniffer dogs can be relied upon to find the unique smell of the disease of in 7 out of 10 sniffers. Researchers from a hospital in Germany believe dogs could become even better at picking out cancer cases with more training, but the final goal is to identify the cancer-specific chemical compounds the dogs can smell, and develop a device that could be used to help diagnose lung-cancer victims at an earlier stage.
Lung cancer is Britain’s deadliest cancer, with over 39.000 cases diagnosed annually, of which only 25 percent will survive for a year, since the disease is mostly found at an advanced stage, when it is very difficult to treat. Early detection is often by chance, although scientists have been working on using samples of exhaled(呼出的) breath from patients for future screening. They attempt to use the samples to locate volatile organic compounds(VOCs) in the breath that are linked to the presence of cancer, but no reliable methods have been found so far that are lung-specific.
The researchers combined this approach with recent findings about the abilities of some dogs to alert their owners to undiagnosed cancer, probably through smell. This latest study used family dogs, which were given special training over an 11-week period to identify a VOC in the breath of patient.
The researches worked with 220 volunteers, including patients with lung cancer at early and advanced stage, patients with chronic pulmonary disease(慢性肺炎), and healthy volunteers. The dogs took part in a number of tests to see if they could reliably distinguish compounds in the breath of lung-cancer patients-even if they smoked. The dogs were asked to sniff glass tubes containing cotton impregnated(浸染) with samples of breath from those taking part and had to lie down if they detected a VOC from a lung cancer patient.
The dogs successfully identified 71 samples with lung cancer out of a possible 100. They also correctly detected 372 samples that did not have lung cancer out of a posible 400.What can we conclude from the research according to the passage?
| A．The volunteers included patients with various cancer successfully |
| B．It used police dogs specially trained over a period. |
| C．It aimed to see if dogs could sniff cancer-specific compounds. |
| D．The dogs identified 372 samples with lung cancer successfully. |

| B．Dogs can usually detect the lung cancer patients well. |
| C．There are about 39,000 lung-cancer patients in Britain every year. |
| D．Lung cancer is Britain’s biggest cancer killer. |
What can be the best title of the passage?
| A．A New Way to Treat Cancer |
| B．A New Way to Detect Disease |
| C．Dogs Can Sniff out Cancer |
| D．Dogs Can Protect People from Cancer |
My name is Amy. I’m a 25-year-old graduate student who likes yoga, home-decorating shows and eating spoonfuls of peanut butter straight from the jar. Oh yeah, and I’m an iPhone addict.
I wasn’t always an addict. In fact, for many years I told myself I didn’t want a fancy cellphone. They seemed like too much work, always ringing and demanding attention. I was perfectly content with my simple cellphone, and I didn’t feel like changing my mind any time.
However, about a year ago, I found myself envious of all those proud iPhone owners, holding their shiny new phones and showing them off to all their friends. I started to eavesdrop on conversations about “iPhone apps”, feeling like a tourist listening to a language I couldn’t speak.
Eventually I couldn’t ignore my iPhone instinct (本能) any longer, and I welcomed my new iPhone into my life. I instantly fell in love with the little bundle of joy, and could no longer imagine a life without it.
To my surprise, I suddenly found myself with a whole new circle of friends—other iPhone owners I could go to for advice and support as I learned the various functions of my new device. They responded to my iPhone-related queries when my other friends couldn’t, and didn’t roll their eyes when I bragged（吹牛）about all the things little Eloise (yes, I named her) could do.
For a couple months I built my new life with Eloise. However, I realized I had a problem when one day I found myself Google-mapping my way to my mailbox, which happens to be right outside my front door.
When I reflected upon the past few months, I couldn’t believe I didn’t see this coming. All the warning signs were there. Eloise slept right beside me and was the first thing I reached for in the morning. I checked my e-mail about 20 times a day. I also experienced attachment anxiety when I left poor Eloise in the changing room at the gym. What if she rang and needed my response? Or, even worse, what if a careless gym-goer knocked her out of my bag and caused her screen to crack?
Once I admitted I had a problem, things started to change. What used to feel like friendly messages now felt like constant complaining to respond. I hated that I could no longer leave the house without Eloise in my hand. Eventually, I felt angry with Eloise so much that I wanted to throw her at the wall.
I decided something had to be done. But, as I quickly realized, iPhones are like cigarettes and not easy to quit.
Then, while taking the bus to work one day, I was unexpectedly forced to quit—at least temporarily. When I reached into my purse to grab Eloise, I found her overcome by fever. My head swam with panic as I attempted to solve the problem, but without result. I couldn’t call anyone for advice. I couldn’t Google whether this had happened to any fellow iPhone owners. The Apple Store was closed by the time I finished work, so I headed home with fear into an Eloise-less night. But, after a couple hours without any text alerts, push notifications, or even good old-fashioned phone calls, I felt ... calmer. Without my electronic bed partner, I drifted off into the deepest sleep I’d had in months. The next morning, I read the news from the simplicity of the newspaper, instead of from my iPhone. I even noticed the cherry blossoms blooming.
My goodness, what had I been missing?The passage is mainly about ___________.
| A．how I changed my attitude towards iPhone |
| B．why I was content with my iPhone |
| C．how my simple cellphone changed my lifestyle |
| D．why I preferred to use iPhone eventually |

| B．She slept with her iPhone beside her every night. |
| C．She checked and read her e-mails too frequently. |
| D．She dared not leave her iPhone alone at the gym. |

| B．She looked forward to starting her new life with Eloise. |
| C．She thought it of little benefit to have a simple cellphone. |

Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.Which of the following is the author most probably in favor of?

Let us suppose it is now about A.D. 2060. Let's make believe it is about 47 years from now. Of course, things have changed and life is very different.
Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment of young and old.
What are people eating now? People are still eating food. They haven't yet started to take on heir(继承) supply of energy directly as electrical current or as nuclear power. They may some day. But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants.
Since there are several times as many people in the world today as there were a hundred years ago, most of our planet's surface has to be filled. The deserts are irrigated with water and crops are no longer destroyed by pests. The harvest is always good.
Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then.
We are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of diseases. No one has to be ill any more.
Such would be our life in 2060.When was the passage written?
A. In about A.D. 2060 B. In about 1960
C. In about 2014D. In about 2013According to the passage, what will be on the moon in about A.D. 2060?

How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.
The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.
The toothbrush will be able to teach you to brush right(don’t forget the insides of the teeth!)and make sure you’re brushing long enough.“It’s kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.
The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth.“We try to make it smart but also fun,” Serval says.
Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said“yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.
The company says the Kolibree will go on sale this summer, for $99 to $199,depending on features. The U.S.is the first target market.
Serval says that one day, it’ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.Which is one of the features of the Kolibree toothbrush?
| A．It can sense how users brush their teeth. |
| B．It can track users’ school performance. |
| C．It can detect users’ fear of seeing a dentist. |
| D．It can help users find their phones. |
What can we learn from Serval’s words in Paragraph 3?
| A．You will find it enjoyable to see a dentist. |
| B．You should see your dentist on a day-to-day basis. |
| C．You can brush with the Kolibree as if guided by a dentist. |
| D．You’d like a dentist to watch you brush your teeth every day. |
Which of the following might make the Kolibree toothbrush fun?
| A．It can be used to update mobile phones. |
| B．It can be used to play mobile phone games. |
| C．It can send messages to other users. |
| D．It can talk to its developers. |
What is Paragraph 5 mainly about?
| A．How Serval found out his kids lied to him. |
| B．Why Serval thought brushing teeth was necessary. |
| C．How Serval taught his kids to brush their teeth. |
| D．What inspired Serval to invent the toothbrush. |
