Exploit your parking space
An unused parking space or garage can make money. If you live near a city center or an airport, you could make anything up to £200 or £300 a week. Put an advertisement（广告）for free on Letpark or Atmyhousepark.
Rent a room
Spare room? Not only will a lodger（房客）earn you an income, but also, thanks to the government-backed “rent a room” program, you won’t have to pay any tax on the first £4500 you make per year. Try advertising your room on Roomspare or Roommateeasy.
Make money during special events
Don’t want a full-time lodger? Then rent on a short-term basis. If you live in the capital, renting a room out during the Olympics or other big events could bring in money. Grashpadder can advertise your space.
Live on set
Renting your home out as a “film set” could earn you hundreds of pounds a day, depending on the film production company and how long your home is needed. A quick search on the Internet will bring up dozens of online companies that allow you to register your home for free—but you will be charged if your home gets picked.
Use your roof
You need the right kind of roof, but some energy companies pay the cost of fixing solar equipment(around￡14,000), and let you use the energy produced for nothing. In return, they get paid for unused energy fed back into the National Grid. However, you have to sign a 25-year agreement with the supplier, which could prevent you from changing the roof.
1.If you earn ￡5000 from renting a room in one year, the tax you need to pay will be based on ______.
A.￡800 B.￡4500 C.￡500 D.5000
2.If you want to use energy free, you have to_____.
A.sign an agreement with the government
B.keep the roof unchanged for within 25 years
C.sell the roof to some energy companies
D.pay around ￡14,000 for the equipment
3.For whom the text most probably written?

The Amazon Echo, a voice-driven cylindrical computer that sits on a table top and answers to the name Alexa, can call up music tracks and radio stations, tell jokes, answer trivia questions and control smart appliances; even before Christmas it was already resident in about 4% of American households. Voice assistants are proliferating in smartphones, too: Apple’s Siri handles over 2bn commands a week, and 20% of Google searches on Android-powered handsets in America are input by voice. Dictating e-mails and text messages now works reliably enough to be useful. Why type when you can talk?
Simple though it may seem, voice has the power to transform computing, by providing a natural means of interaction. Windows, icons and menus, and then touchscreens, were welcomed as more intuitive ways to deal with computers than entering complex keyboard commands. But being able to talk to computers abolishes the need for the abstraction of a “user interface” at all. Just as mobile phones were more than existing phones without wires, and cars were more than carriages without horses, so computers without screens and keyboards have the potential to be more useful, powerful and ubiquitous than people can imagine today.
Voice will not wholly replace other forms of input and output. Sometimes it will remain more convenient to converse with a machine by typing rather than talking (Amazon is said to be working on an Echo device with a built-in screen). But voice is destined to account for a growing share of people’s interactions with the technology around them, from washing machines that tell you how much of the cycle they have left to virtual assistants in corporate call-centres. However, to reach its full potential, the technology requires further breakthroughs—and a resolution of the tricky questions it raises around the trade-off between convenience and privacy.
Computer-dictation systems have been around for years. But they were unreliable and required lengthy training to learn a specific user’s voice. Computers’ new ability to recognise almost anyone’s speech dependably without training is the latest manifestation of the power of “deep learning”, an artificial-intelligence technique in which a software system is trained using millions of examples, usually culled from the internet. Thanks to deep learning, machines now nearly equal humans in transcription accuracy, computerised translation systems are improving rapidly and text-to-speech systems are becoming less robotic and more natural-sounding. Computers are, in short, getting much better at handling natural language in all its forms
Although deep learning means that machines can recognise speech more reliably and talk in a less stilted manner, they still don’t understand the meaning of language. That is the most difficult aspect of the problem and, if voice-driven computing is truly to flourish, one that must be overcome. Computers must be able to understand context in order to maintain a coherent conversation about something, rather than just responding to simple, one-off voice commands, as they mostly do today (“Hey, Siri, set a timer for ten minutes”). Researchers in universities and at companies large and small are working on this very problem, building “bots” that can hold more elaborate conversations about more complex tasks, from retrieving information to advising on mortgages to making travel arrangements.
Many voice-driven devices are always listening, waiting to be activated. Some people are already concerned about the implications of internet-connected microphones listening in every room and from every smartphone. Not all audio is sent to the cloud—devices wait for a trigger phrase (“Alexa”, “OK, Google”, “Hey, Cortana”, or “Hey, Siri”) before they start relaying the user’s voice to the servers that actually handle the requests—but when it comes to storing audio, it is unclear who keeps what and when.

In a new look at the impact of long-time sitting behavior on health， a new study links time watching television to an increased risk of death. One of the most surprising findings is that it isn't just couch potatoes who were affected. Even for people who exercised regularly， the risk of death went up the longer they were in front of the TV. The problem was the long periods of time spent sitting still.
Australian researchers who tracked 8，800 people for an average of six years found that those who said they watched TV for more than four hours a day were 46% more likely to die of any cause and 80% more likely to die of cardiovascular（心血管的）disease than people who reported spending less than two hours a day in front of TV.
Time spent in front of TVs and computers and video games has come under fire in studies in recent years for contributing to a spread of obesity in the US and around the world. But typically the resulting public-health message urges children and adults to put down the Xbox controller and remote and get on a treadmill（跑步机）or a soccer field.
The Australian study offers a different view. "It's not the sweaty type of exercise we're losingsays David Dunstan， a researcher at Baker IDI Heart and Diabetes Institute？ Melbourne？ who led the study. "It's the incidental moving around？ standing up and using muscles. That doesn't happen when we are planted on a couch in front of a television.
Indeed？ participants in the study reported getting between 30 and 45 minutes of exercise a day？ on average.
The results are supported by a new field of research that shows how long periods of inactivity can affect the body's processing of fats and other substances that contribute to heart risk. And they suggest that people can help decrease such risk simply by avoiding extended periods of sitting.
Keeping such processes working more effectively doesn't require constant intense exercise， but consciously adding more routine movement to your life might help？ doctors say. "Just standing is better than sitting，" says Gerard Fletcher， a cardiologist at Mayo Clinic， Jacksonville， Fla. ， who works standing up at his computer. "When you stand up， you wander around a little bit and use muscles not required when you are sitting or lying down. "
Simple strategies for increasing activity include combining household chores such as folding laundry with TV-watching time or getting up to change a TV channel rather than using a remote control.
The report， published Tuesday in the American Heart Association journal Circulation focuses on TV watching partly because it is the main leisure-time activity in many countries？ researchers said， especially in the US.
1.One misunderstanding people might have is that___.
A.couch potatoes were affected by long-time sitting.
B.watching TV is related with increased death risk.
C.watching TV very long is a good way to kill time.
D.regular exercise can minimize the side effect of watching TV
2.What is new about the discovery of the Australian study？___
A.Remote control shouldn't be used when people watch TV.
B.People who watch TV too long should take more physical exercise.
C.Sitting too long in front of TV will lead to high risk of heart attack.
D.Long-time sitting is bad for all people including those who exercise regularly.
3.According to the study？ how can people reduce the risk of death when watching TV？___
A.By increasing simple movement.
B.By totally avoiding watching TV.
C.By taking some medicine.
D.By doing sweaty type of exercise.

阅读下面短文，根据其内容写一篇60词左右的内容概要
Many Chinese students have studied English for approximately ten years, but most of them cannot even speak English correctly or fluently. In my opinion, there are several obstacles(障碍)that have caused this to happen. The main obstacle is fear! Another is the habit of mentally translating from Chinese to English and then to change these thoughts into spoken words and sentences. Many of these difficulties are caused by the way Chinese people study and learn the language.
We must learn to speak as a child does. When we are learning a second language we need to remember how we learned our native language. Learning to understand and speak a language is one of the first skills a child develops. How does a child learn the language? He listens for a time and then he tries to repeat the words. Parents give great praise for the smallest effort and slightest improvement. Therefore, the child develops courage and is excited about learning. It takes a long time before he knows anything about grammar, spelling or formal sentence structures.
As for language teachers, they should avoid criticism(批评)and be very encouraging and generous with praise. Criticism or pointing out faults too often causes students to lose self-confidence and develop a fear of speaking. The best way to motivate a student is using Praise.
The most important aspect of speaking is having self-esteem. Self-esteem is how you feel about yourself. When most Chinese people are asked how their English is, or they are told their English is, or very are told their English is very good, they immediately respond by saying, ''Oh my English is very poor. ''If you say this to yourself often enough, you will believe it. When someone compliments(称赞)you, just say ''thank you ''.
