There is no doubt that the Internet has changed the way that millions of people communicate with the outside world. And there is a lot of buzz and activity around social networking. One of the most interesting opportunities which arise from this is lifestreaming.

When people hang out with friends online, they talk about music, review movies, share travel stories, exchange photos and discuss video games. And they chat about life and recommend books as well.

Lifestreaming is an online record of a person's daily activities. It will allow you to climb inside the head of someone. And you can also experience their day through a digital collection of public text messages, blog posts and photos. What's more, thanks to mobile broadband(宽带) and tiny video cameras, you can also watch a live video stream of them as they move around their world.

Lifestreaming offers the ability to store and broadcast this information exchange. People now can create，collect and publish their interests and activities. They are creating content that reflects their life.

Generally speaking, the lifestreamers have been broadcasting their lives 24 hours a day. Facebook havs now made it possible to load all these other Websites directly into your Facebook profiles. Now users can display their blog posts from their blog. They can display the drunken pictures that they uploaded. The embarrassing videos they have from their YouTube profile can also be shown, and so much more.

Lifestreaming is the newest way to let your friends know what you're up to, and you needn't force them to follow you across many places. Not everyone is into lifestreaming, but it is one of the hottest areas for development out there. And there are a large amount of services offering a way to collect all the little bits of your online life，

Life streaming might be described as a variation of microblogging, because they all focus on the brevity(简洁) of content. But you cannot ignore the difference between them. With microblogging, you write messages directly within the application itself－as you might send a text message. But with lifestreaming application, you collect your other content from around the Web and arrange it into a single stream of short bits of information.

There is no doubt ____ we will host the 2010 World Expo successfully.

高三英语单项填空简单题查看答案及解析

The Intergovernmental Panel on Climate Change released a report stating that the world is quickly running out of time to keep global warming below 1.5 degrees Celsius. To get there, the world would have to cut current emissions by 45 percent by 2030.That sounds absurdly unlikely.

But before we give in to hopelessness，we should remember that the technology to deal with climate change is going along at high speed. The largest source of U. S. carbon emissions is transportation，and a Green New Deal for motor vehicles would be quite straightforward. The reason is simple：with some government subsidies (补贴), electric cars and buses are now cost-competitive with fossil-fuel vehicles. Electric buses have made the greatest speed into the market, because they are a logical choice for electrification. By the end of 2018, electric vehicles were replacing about 280,000 barrels of oil demand per day — about 84 percent of which was mainly consumed by buses.

The electric car market is also reaching maturity, with appealing designs, longer range, and a quickly-expanding rapid charging network in many countries. It’s worth emphasizing that most of the infrastructure (基础设施) necessary to recharge electric vehicles already exists. People often tend to think that we need to replace every gas station, but actually all homes and businesses already have an electrical connection which can be easily improved for fast charging. All that is needed to go fully electric is enough battery capacity and fast charging stations to deal with long trips.

Now America would have to repair its electricity production, freight rail, shipping, and so on to fully decarbonizes (脱碳) the transportation sector, which will be considerably more difficult than simply rooting out fossil fuel vehicles from the market.

But greening America’s vehicle would be straightforward, relatively cheap, and a huge step forward on climate. The politics of climate change are so fearful that being hopeless can seem logical, but the first step to achieving a tough goal is the confident belief that it can be done. And this particular step wouldn’t even be that tough.

1.How’s the goal of keeping global warming below 1.5 Celsius according to Paragraph 1?

A.Reasonable. B.Safe.

C.Realistic. D.Impossible.

2.Compared with fossil-fuel vehicles, electric vehicles now ______.

A.are cost-competitive with government subsidies

B.run at a greater speed on the road

C.deal with longer trips

D.look more appealing

3.What should we do to promote electric cars now?

A.Replace as many as gas stations.

B.Build more infrastructures for recharging.

C.Make businesses have electrical connections.

D.Solve the problem of long trips.

4.According to the passage, what is the author’s attitude to electric vehicles?

A.Negative. B.Supportive.

C.Uncertain. D.Indifferent.

There is no doubt that Apple is well aware of the increased competition in the market and could be in a hurry to put another device out there, said Ramon Llamas, senior research analyst at IDC Mobile Devices Technology and Trends. Given its history with product launches and business policy, though, Apple probably isn’t going to rush an iPhone release simply to put it on shelves, he said.

“If you’re Tim Cook (CEO of Apple), you’re thinking if you want to pay more attention to how to keep growing that bottom line and keep investors happy, or continue with the same approach from Apple, which is do what we can do and manage products and releases in the best way they can work for us. Apple usually does things in their own time ，and I’m having a hard time buying this May or June timeline.” Llamas told Mac News World.

While it，s probable that Apple is definitely in a testing stage for its next smartphone , consumers likely have a standard wait for the finished product, said Colin Gibbs, analyst at GigaOm Pro.

“It typically takes a year or longer to create a state-of-the-art smartphone, so no one should be surprised Apple is in the testing stages with the next iPhone. And while it’s possible that Apple could launch the next iPhone this spring or summer, I’m not expecting to see it until a little later in the year,” he told Mac News World.

When it does launch, though, it could be in a variety of colors, said Gibbs. “Apple has already tested the waters with releasing colored devices when it revamped(更新，翻新）its iPod line last fall, so it’s not too much of a stretch to believe it would want the new twist with its smartphone, as well”.

“I wouldn’t be surprised if the new iPhone becomes available in some new colors，’’ he said. “That could be done pretty cheaply ，and it would give Apple a new marketing angle.”

1.According to Ramon Llamas, Apple always______.

A.tries to pleases its investors

B. does things as planned

C.ignores the fierce market competition

D. rushes to put new products to market

2.As for the next iPhone, Colin Gibbs didn’t mention______

A.the stage of its being tested

B.the rough time of its being released

C.the wide variety of its color

D.the function to be improved

3.What’s Colin Gibbs ，attitude towards the next iPhone?

A. Disapproving. B. Casual

C. Objective.     D. Doubtful.

4.This passage is presented in the form of______.

A.stories   B.comments      C.advertisements D.debates
