5 Secrets of Web Travel Sites

Booking a trip on an online travel site is convenient, but comes with its own set of problems.

1.They who's on a Mac and who's on a PC and who's going to spend more.

Last year, US travel research company Orbitz tracked people's online activities to test out whether Mac users spend more on travel than PC users. On average, Mac users lay out US$20-30 more per night on hotels and go for more stars. according to the Wall Street Journal. As a result, online• travel sites show these users more expensive travel options first. To avoid inadvertently paying more, sort results by price.

2.Their software doesn't always hook up to the hotel's system.

A guaranteed reservation is almost impossible to come by anywhere — but the risk of your flight or hotel being overbooked increases with third-party providers. The middle-man's software isn't immune to system errors, so always call the hotel or airline to make sure your booking was processed.

3.Don't be fooled by packages: Often, they're low-end items grouped together.

Ever notice how travel sites recommend a hotel, a rental car, and tour package all in one click? These deals usually feature travel that no one wants, like flights with multiple layovers.

Check the fine print.

4.You could miss out on loyalty points.

Third-party providers can get between you and frequent flyer miles or points. Many hotel loyalty programmes don't recognise external sites, others award only minimum points and exclude special offers, like double points on hotel stays.

5.Once your trip is purchased, you're on your own.

An online travel agency can't provide assistance the same way an agent can if a flight is cancelled or a room is substandard. Basically, when you arrive at the airport or hotel, you're just another client who booked at the lowest rate.

1.Which ofthe following is TRUE?

A.Third-party providers can ensure your reservation.

B. Mac users are likely to spend more money than PC users.

C.An online travel agency functions the same as an agent.

D.Packages usually provide travelers with satisfactory programmes.

2.What's the purpose of the passage?

A.To encourage readers to book a trip on an online travel　 site.

B. To make an advertisement about several travel sites online.

C. To convince readers not to book a trip on an online travel site.

D.To warn　 readers of some problems with booking　 trips online.

A “blogger” is a person who writes on an Internet computer Web site called a “blog”. The word “blog” is a short way of saying web log, or personal Web site. Anyone can start a blog, and they can write about anything they like.

There are millions of blogs on the Internet today. They provide news, information and ideas to many people who read them. They contain links to other Web sites. And they provide a place for people to write their ideas and react to the ideas of others.

A research company called Peruse has studied more than 3,000 Web logs. It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year.

However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products.

At the same time, some long-standing blogs have ended. Last week, blogging leader Dave Winner closed his free blog service, weblogs.com. He says the site became too costly to continue. He started the blog four years ago, and thousands of people had written on it.

One blog that is still going strong is called Rebecca’s Pocket. It involves much useful information for readers. Rebecca Blood created the Web site in 1999. She wrote about the history of blogs on the site. That article led to a book called “The Weblog Handbook”. It has been translated into four languages so far.

Ms Blood says Rebecca’s Pocket gets about 30,000 visitors a month. She writes about anything and everything----politics, culture and movies. She recently provided medical advice. And she wrote about how to prevent people from stealing money from online bank accounts.

1.The text is written mainly to ____

2.From the text we can learn that blogs cover almost everything except __ _.

3.According to this passage , which of the following is NOT true?

4. The reason why Rebecca’s Pocket is still going strong is that____

The announcements by the NASA，in the form of several Web site postings and a video posted on YouTube，were in response to worries that the world will end on Dec．21，2012．

The doomsday(末日) rumour reached a high point with the release of the new movie “2012”，directed by Roland Emmerich．In the movie，Yellowstone blows up, showering the continent with black ash．Tidal waves wash over the Himalayas，where the governments of the planet have secretly built a ship which a select 400，000 people can ride out the storm．There are hundreds of hooks devoted to 2012，and millions of Web sites，depending on what combination of“2012”and“doomsday”you type into Google．All of it，astronomers say, is nonsense．“Most of what's claimed for 2012 relies on wishful thinking and ignorance of astronomy．”Ed Krupp， an expert on ancient astronomy，wrote in an article in the November issue of Sky＆Telescope．

“I get angry at the way people are being influenced and frightened to make money,” Morrison said．“There is no right to frighten children to make a buck．”suggested David Morrison，an astronomer at the NASA Ames Research Center in Moffett Field，Calif．He said he had been getting about 20 letters and e—mail messages a day from people as far away as India scared out of their wits．Morrison said he did not blame the movie for all this，as much as many other supporters of the Mayan prediction．But then，he said，“my doctorate is in astronomy，not psychology．”

In an e—mail exchange, Krupp said：“We are always uncertain about the future，and we always consume representations of it．We are always attracted by the romance of the ancient past．”A NASA spokesman，Dwayne Brown，said the agency did not comment on movies，leaving that to movie critics．But when it comes to science, Brown said, “we felt it was careful to provide a resource．”

If you want to worry，most scientists say，you should think about global climate change or nuclear war．But if ancient prophecies(预言)get you going，here are some things Morrison and the others think you should know．

64．Which of the following statements is TRUE according to the passage?

A．Dr．Morrison blamed the Movie“2011”for the panic it aroused in the public around the world．

B．People who watched the movie were seared and firmly believed that the end of the world was coming．

C．In terms of science it was better to provide evidence and theory at the same time．

D．Dr．Morrison thought it was not right to make money by frightening people．

65．It can be inferred from the text that         ．

A．astronomers think that doomsday is likely to happen in the near future

B．the reason why the NASA posted web site postings was to make people interested in astronomy

C．scientists think we shouldn't worry about doomsday but show concern about environment protection

D．most astronomers agree that the world is not ending—at least anytime soon

66．Which of the following would be the best title?

A．A New Movie“2012”             B．Is Doomsday Coming?

C．End-of-the-World Stories          D．Astronomers Comment on Movies

67．What would the author probably discuss in the paragraph that follows?

A．Evidence that the Mayans thought something special would happen in 2012．

B．What will really happen in 2012．

C．The reason why there is no need to worry about doomsday．

D．Ancient stories about the end of the world．

With the Covid-19 virus sweeping the globe, the science on quitting smoking offers welcome news for smokers who want to build up their defenses in case they contract the virus. Though it may still take many months for a smoker's lungs to heal from damage caused by long-term smoking, your health can noticeably improve in the days and weeks after quitting in ways that could make a difference against the virus. Covid-19 creates an added sense of urgency, and there's enough reason to believe that quitting smoking during the pandemic（流行病）could increases your opportunities of fighting off the virus.

If you make the decision to quit, the cilia（纤毛）in your lungs are one of the first parts of your body to heal. These hair-like projections wave back and forth like a brush as air moves in and out of your lungs. They help your body fight off colds and infection. They also help clear mucus（黏液）, so if they're not functioning as well as they should, mucus can build up in the lungs. Your body's tendency to cough during an infection helps inspire the bodily process of clearing out mucus. That's vital in fighting the Covid-19 condition. The elderly are at a greater risk for too much lung fluid that often limits breathing following coronavirus infection because they don't have a strong enough cough to clear it up.

A second short-term gain from quitting smoking comes from reducing ongoing inflammation（炎症）in your body, which can make you infect Covid-19 more easily. Having your lungs in as good of shape as you can in case of a corona virus infection is key.

Besides lung-related issues, quitting smoking can also deliver healthy benefits to the heart that could help prevent possible heart attacks, which are another cause of death in Covid-19 cases. After you quit smoking, your blood becomes thinner and less possible to setting. Heart attacks are less likely. One reason this happens is because smoking makes it harder for the heart to distribute blood throughout the body.

1.What is the use of the lung cilia?

A.Cleaning up the lungs. B.Killing the Covid-19 virus.

C.Predicting lung infections. D.Reducing breathing difficulty.

2.Why are the old at higher risk to the corona virus?

A.They cannot go out during the pandemic. B.There is too much mucus in their lungs.

C.Most of them are heavy smokers for years. D.They are lacking in the care of their children.

3.What good does quitting smoking do to heart？

A.Strengthen the heart muscle. B.Turn blood to be much thicker.

C.Make the blood flow smoother. D.Speed the heartbeat up apparently.

4.What is the text mainly about？

A.Quitting smoking can help defend the Covid-19.

B.Ways to make a difference against corona viruses.

C.The Covid-19 virus is threatening humans worldwide.

D.Protecting the smokers' lungs to heal from damage.
