Unknown to most Facebook users, the social network actually offers a lot of privacy controls and security features which can help you lock your account, so you can speak freely. If it’s used properly, you’ll never have to worry about whether you will have to “friend” your boss or your mom. You can friend anyone you want while staying comfortable in the knowledge that not everyone gets to see everything you post.

   The problem with carrying out these privacy options is that they’re just too confusing for most non-tech clever people to handle. And often, most people don’t want to bother to take the time to learn. To simplify the process, we’re offering one easy step you can take today to help make your Facebook experience safer, more secure, and more private.

   Just make “Friend Lists”. Yes, it will take some time, especially if you’re connected to a couple of hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook.

   Friend lists, as the name suggests, are lists for classifying your friends into various groups. The nice thing about this feature is that once you set these lists up, you won’t have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list named “Work”, personal friends you’re not very close with into a list called “Acquaintances”, and people you’re related to into a list called “Family”. Those three main categories will separate out the groups of “friends” who you may want to hide some information from.

   To create a friend list, click on “Friends” at the top of the Facebook homepage. In the left-hand column, click “Friends” again under the “Lists” section. Now you’ll see a button at the top that says “Create New List”. Click it. In the pop-up that appears, you can name your list and pick members. If you’ve ever shared an application with your friends, the process of doing this will be very familiar.

   When you’ve finished making lists, you’ll be able to use them when selecting who can see what (or who can’t!) when configuring (配置) the security settings described below.

There is an English saying :“laughter is best medicine .”Until recently ,few people took the saying seriously .Now however ,doctors have begun to look into laughter and the effects it has on the human body .They have found that laughter really can improve people’s health .
Tests were carried out to study the effects of laughter on the body .People watched funny films while doctors checked their hearts ,blood pressure ,breathing and muscles .It was found that laughter had similar effects to physical exercise .It increases blood pressure ,the heart beating and breathing ; it also works several groups of muscles in the face ,the stomach ,and even the feet .If laughter exercises the body ,it must be beneficial .
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body .In one experiment doctors produced pain in groups of students who listened to different radio programmes .The group that tolerated(忍耐)the pain for the longest time was the groups which listened to a funny programme .The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain .
As a result of these discoveries ,some doctors in the United States now hold laughter clinics ,in which they help to improve their patients’ condition by encouraging them to laugh .They have found that even if their patients do not really feel like laughing ,making them smile is enough to produce beneficial effects similar to those caused by laughter .

Who are these people rushing by you on the street? More than 250 million people now call Amer??ica" home" , but most of them can trace their families back to other parts of the world. If you, look at the names on shop windows, you will see that Americans come from many different lands. The idea that these people, who once were strangers to the United States，have lost the customs and cultures of their original countries and have become "Americans"is really not true. In fact, what exists in Ameri??ca is - more often a kind of “ side - by - side" living in which groups of people from other countries often have kept many of their own customs and habits. They join the general American society only in certain areas of their lives such as in schools，business，and sports一but they keep many of their own native customs and manners socially and at home. This “ side - by - side" living has both advantages and disadvantages. Sometimes it may cause disagreements to develop between groups whose ways of life are very different from one another. However, there are also great advantages that come from the variety of cultures brought by settlers from other lands. There is great freedom of choice among ideas ’ dress, food, and social customs in America. Everyone can find some part of his or her own familiar world in the United States, in churches, music, food, national groups, or newspaper.

The Carnival of Brazil is an annual festival held 46 days before Easter, especially famous for the Carnival in Rio de Janeiro. Carnival celebrations are believed to have roots in the festival of Saturnalia, which, adapted to Christianity, became a farewell to bad things in a season of religious discipline to regret and prepare for Christ’s death and coming back to life.
Modern Brazilian Carnival dates back to Rio de Janeiro in 1641. It originally copied the European form of the festival, later taking in elements of Native American and African cultures.
In the late 19th century, the strings (弦乐器) were introduced in Rio de Janeiro. These were pageant (游行) groups that paraded through city avenues performing on instruments and dancing. Today they are known as blocks, consisting of a group of people who dress in costumes or special T-shirts with themes or logos. Blocks are generally connected with particular neighborhoods; they include both a music group and a lot of revelers.
Block parades have become an expressive feature of Rio’s Carnival. Today, they number more than 100 and the groups increase each year. Blocks can be formed by small or large groups of revelers with a clear title. Before the show, they gather in a square, then parade in sections of the city, often near the beach.
Carnival time in Rio is very interesting, but is also the most expensive time to visit Rio. Hotel rooms and other lodgings (住宿) can be up to four times more expensive than the regular rates. There are big crowds at some locations and life is far from ordinary in many parts of town.
【小题1】What can we infer from the first paragraph?

"It's this time of year when the weather starts warming up and frogs start breeding - but they haven't been breeding," says John Wilkinson, research and monitoring officer at the Amphibian and Reptile Conservation Trust (ARC).
Amphibians (两栖动物) are just one of the groups of animals that nature observers fear may have problems reproducing this year, as groundwater levels are even lower now than in the infamously dry summer of 1976, according to the Department for Environment, Food and Rural Affairs (Defra). According to the UK's Centre for Hydrology and Ecology the average rainfall so far this winter has been the lowest since 1972.
"If ponds dry up totally," says Mr. Wilkinson, "you could have lots of dead tadpoles." Drier and windier conditions could also make it more difficult for juvenile amphibians to survive their journeys between wet habitats.
But Peter Brotherton, the biodiversity manager for Natural England, says that "drought is part of nature's cycle", and, at present, a lot of animals, plants and insects are still in hibernation. This means that the population picture is unclear. "However, when we get extreme events, we get animals dying," he says. "And what is worrying is that normally at this time of year we expect soil to be near saturation（湿润）after winter."
Charlie Kitchin, the RSPB's site manager of the Nene Washes in Cambridgeshire, says the 2,000-acre wetland and grassland area is now struggling following two winters with relatively little winter rain and no flooding. One species that could suffer, he says, is the black-tailed godwit（黑尾豫）. "There are only 50 breeding pairs in the country, and we have 40 of them, and everything is bone-dry," Mr Kitchin says.
But one bad nesting season, he says, is "not the end of the world". "One of the features of flood plains is that they're volatile anyway," he adds. "But if they fail to breed another year, the population is likely to dip again."
