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... What function isn't understood by most people on Facebook? A) Surfing the Internet. B) Setting safety protection. C) Sharing personal information. D) Making foreign friends.

Q: A weather map is an important tool for geographers. A succession of three or four maps presents continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts to determine whether an individual pressure aroa is deepening or becoming shallow and whether a front is increasing or decreasing in intensity .They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal a summary picture of conditions in the atmosphere at a given time. All students of geography should be able to interpret a weather map accurately.Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States Weather Bureau issues information about approaching storms, floods, frosts and all climatic conditions in general. Twice a month it issues a 30-day"outlook" which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlooks are based upon an anaiysis of the upper air levels which often set the stage for development of air masses, fronts and storms. Considerable effort is being exerted today to achieve more accurate weather predictions, with identifying and tracking storms over regions which have but few meteorological stations. Extensive experiments are also in progress for weathef modification studies. The observation of weather conditions by satellites is helpful because it _ A) is modern B) uses electronic instruments C) makes weather prediction easier D) shows things that would otherwise take hours to describe in a few minutes

Thirty-two people watched kitty Genovese being killed right beneath their windows. She was their neighbor. Yet none of the 32 helped her. Not one even called the police. Was this in gunman cruelty? Was it lack of feeling about one's fellow man? Not so, say scientists John Barley and Bib Fatane. These men went beyond the headlines to probe the reasons why people didn't act. They found that a person has to go through two steps before he can help. First he has to notice that is an emergency . Suppose you see a middle-aged man fall to the side-walk. Is he having a heart attack? Is he in a coma from diabetes ? Or is he about to sleep off a drunk? Is the smoke coming into the room from a leak in the air conditioning? Is it steam pipes? Or is it really smoke from a fire? It's not always easy to tell if you are faced with a real emergency. Second, and more important, the person faced with an emergency must feel personally responsible. He must feel that he must help, or the person won't get the help he needs. The researchers found that a lot depends on how many people are around. They had college students in to be tested. Some came alone. Some came with one or two others. And some came in large groups. The receptionist started them off on the tests. Then she went into the next room. A curtain divided the testing room and the room into which she went. Soon the students heard a scream, the noise of file cabinets falling and a cry for help. All of this had been pre-recorded on a tape-recorder. Eight out of ten of the students taking the test alone acted to help. Of the students in pairs, only two out of ten helped. Of the students in groups, none helped. In other words, in a group, Americans often fail to act. They feel that others will act. They, themselves, needn't. They do not feel any direct responsibility. Are people bothered by situations where people are in trouble? Yes. Scientists found that the people were emotional, they sweated, they had trembling hands. They felt the other person's trouble. But they did... The researchers have conducted an experiment to prove that people will act in emergencies when _ . A) they are in pairs B) they are in groups C) they are alone D) they are with their friends
