Visitors worry that London is an expensive city but there really are so many things to do for




free in London from museums and galleries to free music and walking tours.
Art Galleries
Tate Modern and Tate Britain are exceptional national art galleries housing some of the finest artworks in the world. Tate Modern focuses on contemporary art while Tate Britain displays British Art from the sixteenth century to the present day.
Museums
All of London's major museums are free, but most offer some special exhibitions for a fee. My favorite is the Museum of London where you can learn the history of London from Roman times to today. Other great major museums are the British Museum, the V&A, the Science Museum, and the      Natural History Museum. Oh, and I love the Geffrye Museum. And the. Now I can't decide which is the best!
Many of London's major art galleries and museums are open in the evening and often have special evening events. This can be a great way to relax at the end of a busy day seeing the sights. The main London galleries and museums are air-conditioned so it can be a wonderful way to cool down in the height of summer in the city. Galleries and museums are not open late every night so here is a handy list to help you plan your days and evenings.
Royal Parks
Many people say the Queen Mary's Rose Gardens in Regent's Park is their favorite spot in London, and who am I to argue? I would also recommend St. James's Park as it offers one of the best views of Buckingham Palace. Hyde Park is enormous and includes the ever popular Diana Memorial Fountain and the Peter Pan Statue.
There are often free talks and guided walks in the royal parks so do check the What's On section of the Royal Parks website.
Changing of the Guard
No visit to London is complete without seeing this military tradition. The Queen's Guard in London changes in the Forecourt inside the gates of Buckingham Palace at 11:30am every day in the summer and every other day in the winter. Get there early and view the spectacle from outside the front gates.

If I see one more article about how wonderful alternative energy is compared to oil, I will flip(翻页). Alternative energy sources can be good---- very good in fact. And it’s pretty obvious that we’re going to need them, and that our dependence on oil is a Bad Thing. But accepting that does not mean accepting that any kind of alternative energy is a good thing.
To be a good thing, it has to have three properties: 1) It has to help reduce our dependence on oil, 2) It has to be no worse for the environment, and 3) It has to be economically practical.
Many of the things praised meet one or even two of those properties. Solar panels, for example. They can reduce our need for oil, at least in certain regions, and they’re certainly not bad for the environment. But they’re expensive. If you spend the money to make your home solar-powered, you probably won’t get back your costs for at least 15 years, which approaches the lifespan of the panels.
Certainly we need to clean up our act big time and find workable sources of alternative energy. But we also have to keep in mind that every one of these alternative-energy sources comes at a cost, which is something people seem to forget. They hear the phrase “alternative energy” and automatically assume it’s got to be good. But green isn’t always good, and oil isn’t always bad.
One seemingly “green” technology that pops up again and again is electric cars. It is praised by well-meaning people as good for the environment and a way to reduce our oil dependence, especially as oil prices continue to rise.
Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.
People in California love to talk about “ zero-emissions vehicles”, but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something---- usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal（地热的） plants as well, but by far we get electricity mainly by burning something.
In other words, those “zero-emissions” cars are likely coal-burning cars. It’s just because the coal is burned somewhere else that it looks clean. It is not. It’s as if the California Greens are covering their eyes ---- “ If I can’t see it, it’s not happening. “ Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas ( or another fue) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat ---- at the generator, through the transmission（传送） lines, etc.
A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won’t get you nearly as far ---- so electric cars burn more fuel than gas- powered ones. If our electricity came mostly from nukes; or geothermal, or hydro, or solar, or wind, then an electric car truly would be clean. But for political, technical, and economic reasons, we don’t use much of those energy sources.
In addition, electric cars’ batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it’s a power plant, though, all the junk is in one lace. Nature is very good at cleaning up when things are too concentrated, but it takes a lot longer when all the garbage is in one spot.
【小题1】Which of the following statements will the writer support?

“Mobile phone killed my man,” screamed one headline last year. Also came claims that an unpublished study had found that mobile phones could cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones could heat the brain.
For anyone who uses a mobile phone, these are worrying times. But speak to the scientists whose work is the focus of these scares and you hear a different story.
One of the oddest effects comes from the now famous “memory loss” study. Alan Preece and his colleagues at the University of Bristol placed a device that imitated the microwave radiation of mobile phones to the left ear of volunteers. The volunteers were good at recalling words and pictures they had been shown on a computer screen. Preece says he still can’t comment on the effects of using a mobile phone for years on end. But he rules out the suggestion that mobile phones have an immediate effect on our cognitive（认识的）abilities. “I’m pretty sure there is no effect on short-term memory,” he says.
Another expert, Tattersall, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses（神经元突触） exposed to microwaves become more — rather than less — receptive to undergoing changes linked to memory formation.
An even happier outcome would be that microwaves turned out to be good for you. It sounds crazy, but a couple of years ago a team led by William Adey at the Veterans Affairs Medical Center in California found that mice exposed to microwaves for two hours a day were less likely to develop brain tumours when given a cancer-causing chemical.
“If it doesn’t certainly cause cancer in animals and cells, then it probably isn’t going to cause cancer in humans,” says William. And while there’s still no absolute evidence that mobile phone use does damage your memories or give you cancer, the conclusion is: don’t be afraid.
【小题1】 Mobile phone users are worried because ______.

A．they are not sure whether mobile phones can cause memory loss

B．it’s said that mobile phones have a lot of side effects

C．one headline reported “Mobile phone killed my man”

D．a British newspaper showed mobile phones could heat the brain

With his game-winning three-pointer at the buzzer, Jeremy Lin (林书豪) finished the New York Knicks' dramatic reversed victory to defeat the Toronto Rapters.

The Knicks have won six games in a row, and Jeremy Lin has put up impressive numbers during the continuous period of competitions. Although the season is still young, the Knicks have reversed course in just one week from the NBA's most disappointing team to a playoff (季后赛) contestant. Lin, not team's high-paid stars, has saved the Knicks season and likely coach D'Antoni's job.

After nearly 15 years of disappointing, sometimes unsuccessful seasons, Madison Square Garden is alive again, and New York City can't stop talking about the Knicks. To put things into perspective, consider this: Just several years back, Knicks fans protested nightly outside of the Garden calling for the team's ownership to fire their resented coach Isiah Thomas.

Now, Madison Square Garden Co. shares are at a record high, the Knicks' average household television rating is up 70 percent since Lin joined the starting lineup (首发阵容), and jersey sales are increasing very quickly. I watched the Knicks-Lakers game at a bar in Harlem, and have not felt that kind of energy from fans since the great playoff between the Knicks and Miami Heat in the late 1990s.

Beyond the Knicks, Lin may be saving the NBA as well. Just a few months back, the NBA took a massive credibility hit during a multi-month lockout, where the owners did not allow the players to go back to play until they accept the new salary levels. As a consequence, the season did not even begin until Christmas Day. Over the past few years, LeBron James' (勒布朗﹒詹姆斯) relatively long and unpleasant free-agent (自由职业球员) events, combined with poor play around the league, have angered fans and damaged the league's brand.

Lin is leading a one-week NBA basketball revival. His legendary story has inspired Asian-Americans, increased NBA sales in China, and turned the basketball world upside down.

Free energy is everywhere around us. There are many ways to make and collect energy from various sources like sun, wind and water. People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world.
So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls (过路费)? Why don’t we use them for collecting energy?
The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work?
The Solar Road Panels will contain embedded (嵌入的) LEDs which “paint” the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour (绕行) ahead. The road will be able to sense wildlife on the road and can warn drivers to “slow down”. There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving.
Replacing asphalt (沥青) roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips.
We just can’t wait to see more of these roads all over the world in the near future.
