Your car is a necessary part of your life. You use it every day. Of course, you want to hold on to it so you make sure it has the latest alarm and immobilizer. But despite all these, cars like yours are still stolen every day. In fact, in this country, one car is stolen almost every minute! And if your car is stolen, you only have a 50:50 chance of seeing it again.
Each year, car crime costs nearly £3 billion. Of course, if you’re insured, you won’t lose out, or will you? Firstly, you will have to pay extra insurance later on, and then you may not be offered the full amount by the agent. You will probably have to hire a car and you will also lose the value of the contents and accessories (配件) in the car.
Now comes the solution. An RAC Trackstar system, hidden in one of 47 possible secret locations in your car, is the key of our system. If your car is stolen, radio signals are sent at twenty-second intervals from the car to the RAC Trackstar National Control Center via a satellite network. Then a computer gives the vehicle’s exact location, speed and direction.
The RAC Trackstar National Control Center, which operates 24 hours a day, 365 days a year, will immediately inform the police in the area where the car is located. Because the police receive information every twenty seconds, they will always know the vehicle’s location. Once the thief has been arrested, your car will be returned to you.
RAC Trackstar is unique in being able to provide the National Control Center with details of the exact location of your car, its speed and direction. And speed is the key to successful recovery of a stolen vehicle. RAC Trackstar Control will immediately tell the police if you report your car stolen and under the 24-hour Guardian Option. It will also tell you if your car has been stolen. RAC Trackstar’s constant updates mean the police are kept informed of the car’s location. All these greatly improve your chances of seeing your car again.
If your car is stolen, you will have to ______.
| A．hire a new car |
| B．pay more insurance |
| C．buy a RAC Trackstar system |
| D．inform the National Control Center |
The Trackstar system can tell the police ______.

A fly with an extremely unusual ability to hear is the model for what may be the future of new and improved hearing aids. The insect behaves like a parasite—an organism that lives on or in another organism called a host. This exceptional fly places larvae—young flies onto a cricket (蟋蟀) host. The larvae dig into the cricket and eat the insect from the inside out.
The tiny yellow fly lives in Central America and the Southern United States. It finds its host by listening out for the cricket’s high chirping voice. The fly can easily find a cricket from as far away as 91 meters.
Neal Hall is a sound engineer who worked on the new hearing aid model. According to him, the fly’s behavior is very strange. Mr. Hall and his team at the University of Texas made a copy of the fly’s hearing structure. “They discovered that the fly has a clever mechanism and instead of using two independent ears like a human does, the fly’s ears are actually coupled,” said Hall.
The fly’s ears are two millimeters apart. That distance is so small that sound reaches one ear just four millionths of a second before arriving at the other. Experts held that it should be impossible for the fly to identify where a sound is coming from. In fact, however, inside this fly’s each ear is a 1.5-millimeter-long structure similar to a see-saw — a piece of children’s playing equipment. Like the see-saw, the fly’s ear structure goes up and down from a central point. Pressure waves against the structure increase the time it takes for sound to travel and permit the fly to find its host.
Mr. Hall and his team used the chemical element silicon to copy the fly’s ear structure. They also used the special electric materials that enabled them to measure its movements at the same time. Hall said that the hearing aid device could be used in two ways. One way would be to help the military on the battlefield, where sensors could find where shots are coming from. The other would be to remove unwanted noise from a person’s surroundings.
“It is a feature that is incredibly useful for hearing aids, for example, here and now, if you turn up the gain of a hearing aid or turn the volume up to hear someone across from you, it also amplifies (放大) everything else in the room,” said Hall.
Hall said that the next test in marketing the hearing aid device was to make it usable. He said the device must be handled carefully because it is so small. He noted that the fly does not have this concern.Neal Hall is trying to .
| A．model his new hearing aid on a kind of fly |
| B．help crickets to prevent themselves from parasites |
| C．kill the insects in a host with a new machine |
| D．make powerful killers with the help of a kind of fly |

| B．The special structure of the fly’s ears. |
| C．The comparison between the fly’s ears and see-saws. |
| D．Pressure waves against the structure of the fly’s ears. |
With the help of the new hearing aid, people would be able to .
| A．find out where the flies come from |
| B．fall asleep when they want to |
| C．protect the peaceful environment better |
| D．choose to hear what they want to |
What is the author’s attitude towards Neal Hall and his team mentioned in the passage?
| A．Objective. | B．Tolerant. |

I love my job. I’m trying to understand how plants build themselves out of thin air. It’s exciting, and it’s creative. I like working with other people with different views and I like the sharing of ideas and the piece-by-piece building of understanding by careful observations, experiments and analyses. Then there are those rare moments when suddenly something that is understood clearly makes sense and unconnected ideas fit together to make a satisfying whole.
All these motivations for life as a researcher are evident in the results of a survey to examine the culture of scientific research in the U.K. But the survey has also uncovered threats to the vibrancy (活跃) of this intellectual melting pot. With the expansion of the scientific enterprise, the current squeeze on resources and the drive towards more assessment, researchers are spending increasing amounts of time competing for funding and jobs.
Some aspects of research assessment are reasonably objective: Have these experiments been designed carefully? Does this researcher use the techniques? However, many aspects are fundamentally subjective: Are these projects exciting? Will this person revolutionize the field? All these judgments take time and carefulness, and all of them require the judges to accept the subjectivity of the exercise.
Researchers are now assessed almost entirely on the research papers that they have published in peer-reviewed journals. These are easier to assess than important but less-definite qualities such as public engagement and training, and support provided for colleagues. Publishing in important journals is still thought to be the most important element in determining whether researchers gain funding, jobs and promotions or not. It can lead to a wide range of non-ideal practices, such as over-claiming the significance of research findings, sticking to very fashionable areas of science and leaving important but confirmatory results unpublished due to lack of encouragement to spend time writing them up.
If research stops researchers finding out how the world works for the benefit of society, and makes them compete to get their work published in a particular journal, then the most creative and brilliant people will go and do something else. The people who stay in research will be those mostly encouraged by wanting to look good according to some semi-arbitrary standard. This is causing widespread unease in the research community.
We hope the findings of the survey will stimulate the debate about how to shift the culture back to its roots in creativity and invention, coupled with strictness and openness. If left unchallenged, the current trends will certainly influence what science gets done and therefore what we learn about the world. This is not just some mysterious academic debate, and it matters to everyone.The results of a survey prove that .
| A．all the researchers can work together |
| B．some research scientists have done makes no sense |
| C．all the aspects of research assessment are reasonably subjective |
| D．researchers are spending amounts of time competing for kinds of motivations |
What most affects researchers’ gaining funding?
| A．How many papers they have published in important journals. |
| B．How much support they have given to their colleagues. |
| C．How many people have quoted from their papers. |
| D．How much they are engaged in research. |
What can we learn from the passage?
| A．The quality of research needn’t be valued. |
| B．The current assessment on research must be used. |
| C．It’s necessary to build a scientific research culture. |
| D．Researchers should spend their funding as soon as possible. |

Positive Thinking, With a Little Help From Your Phone
Here are some apps （程序）on your phones which can help you think positively or aim at happiness. Examine them, and you can have fun .
Happify is perhaps the most popular positive app available now. By asking some questions about your goals in using the app, it recommends you some tracks.
Each track contains games and activities that guide you to seeing positive aspects of your daily life. It also regularly helps you assess your happiness level, pointing out how you can feel more positive merely by changing your habits. There’s also a community page in the app where you can see inspirational comments by other users and even upload your own .
Happify’s only drawback is that while it’s free to download and use, access to its full range of activities costs $13 a month or $70 a year.
Other apps use a different route to developing positive thinking habits. They simply expose you repeatedly to motivational ideas, quotes and suggestions.
Positive Thinking is a relatively simple attempt at this kind of app. It uses colorful imagery and simple controls, and has a list of motivational quotes and suggestions — everything from “do sports” to “stop thinking ... sit there relaxed.” It’s extremely basic, and there’s not a huge amount of content but you may find it has some good ideas and it’s free.
The app Mood Journal, which costs $2, has a great-looking. Through text-entry controls you can make a diary-style note in the app of when you’re feeling positive, and also add a photo. When you’ve accumulated enough entries, the app presents some analytics in the form of graphs that show your positivity over time. This could help you plan strategies to be more positive. , and also add a photo or a selfie.
If you prefer a more meditative approach to positive thinking, check out Smiling Mind, a free iOS and Android app. You enter data on how you’re feeling, using a number of slide controls that ask if you’re feeling “stormy” or “calm,” for example. Then you listen to a meditation-like voice track that talks you through different programs.How does Happify help you think positive?

B Resort & Spa
Disney World presents a dilemma for many people. If you’re there, you’re probably there because you love the children in your life. But should that noble desire to do right by the wee ones automatically put you in a disgusting holiday of six-foot animated characters, wailing toddlers and chicken-finger meals?

There’s 80-minute B Indulged massages to be had at the Aveda spa, complete with footbaths for your weary feet, and adventure tours to nearby Boggy Creek to observe tigers in their natural habitat. Even the mini-bar is stocked with a nod to grownup tastes (think Boulder Canyon natural, kettle-cooked chips).
location
B is right inside Orlando’s Walt Disney World Resort, just a short, free shuttle from Downtown Disney. This means you don’t have to stay in the kid zone all day long.
