Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives -either recorded or real-may even prevent elephants from damaging farmer's crops. In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away. Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next,Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family. From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place. Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away. We know from the passage that elephants may be frightened of _ . A) loud noises B) some crops C) video cameras D) angry bees

More than 20 million kids in the United States live with one parent. Separation and divorce are the most common reasons for this. In other cases, the mom and dad may never have lived together, or one of them may have died. Living with one parent instead of two can bring about a lot of emotions. These feelings can be pretty strong, and they can be confusing, too. You might feel terribly sad and angry because your parents divorced. Single parents are often working parents because someone needs to earn money to buy food, clothing, and a place to live in. Having a job means your mom or dad is able to provide these things and more for you. People work for other reasons, too. A job can let a person use his or her special talents and skills. A job can be important because it helps people in the community. But even though you might understand why your mom or dad has to work, sometimes it can be hard to accept. This can be especially true during the summer or school vacations. _ It can be tough when you don't have enough time with your dad or mom. When you live with one parent, that person really has to do the work of two people. Besides a job, your mom or dad is responsible for caring for the kids, the house, the yard, the car and the pets. So what can you do ? One of the best ways is to hold a family meeting. Talk about everyone's schedule for work, school, and activities.

Maybe you can also schedule a weekly game or a movie at night. What is the best title for the passage? A) Living with a single parent B) Single parents and work C) How to work with a single parent D) Schedules for work

Ques: As soon as you meet, or even see, a person, you form an impression of him based on his posture, gesture and facial expressions. This is why it is important to make a good first impression on the person who will be interviewing you. Within the first 60 seconds of meeting you, the interviewer will have formed an impression about what type of person you are and what kind of employee you would become, and 55% of this will be based only on your body language. Here are some tips to make you that impression a good one. First of all, relax. Think positive thoughts and you are more likely to come across as a positive, confident person during the interview. Dress smartly, as your appearance is one of the first things an interviewer will notice you. Stand up straight, and walk in with your shoulders back and your head up. Try to avoid slowing down as you walk into the room because this suggests fear and uncertainty. Shake hands with the interviewer firmly. You should have a positive handshake and a warm smile. Open your coat or jacket as you sit down shows that you, too, are open. Posture is important. You should be sitting well back in your seat. Sit up straight and lean forward slightly, but not too much. Sitting at too much of an angel expresses discomfort and distrust. Two of the most common signals are crossing your arms and legs, so try to avoid them. Another important issue is eye contact. Looking someone in the eye shows confidence in yourself and trust in the other person. However, don't overdo it, as too much eye contact or starring will make the other person uncomfortable. Use more eye contact when listening than when talking, and when you look away, look down. Looking up at the ceiling will make you seem bored and rude. What is the best title for the passage? A) How to use body language to win an interview B) How to answer questions in an interview C) How to understand body language D) How to deal with an interviewer

Ques: What is art? According to one definition, it is the creation of something that appeals to our sense of beauty. This definition may include painting, drawing, sculpture, and architecture, or performing arts such as music and drama. Cultural and historical influences, as well as one's own consciousness of what is aesthetically( )pleasing, play a role in what one believes to be art. To some people, art is the description of an object--- a painting or sculpture of a person, for example. For others, art may be a blank canvas, or a piece of chalk. In order to talk about the different artistic styles that have existed over time, art historians have classified these styles into different periods and organized them in chronological order. The works of art produced within each period mirror the culture and events of that time. The earliest forms of art, from the prehistoric era , include simple cave paintings and figures made from stone. There were followed by the sculptures and carvings of Ancient Civilizations era. Styles of the later Classical era (800 B.C. to 200 A.D.), reflect the culture of the time--- one that favored simplicity and balance. The period of the Middle Ages followed, and was succeeded by a revival of classical styles in the Renaissance era, beginning around 1400. Well-known artists of this time include Michelangelo and da Vinci. One hundred years of Baroque style, and then fifty years of Rococo followed the 200-year Renaissance. The start of the nineteenth century saw the rise of the Premodern era, followed by the Modern era, a period that lasted until 1945. This was followed by Postmodern era that characterizes the present day. In addition to differences in artistic styles between eras, there are also differences within each era. The Postmodern era, for example, has featured innovative artistic styles such as Pop Art ( which includes work by Andy Warhol), Minimalism, and Conceptualism. Since the 1960s, Conceptualism has grown in popularity. This style focuses more on the idea or 'concept' of... According to the passage, art historians have classified these styles into _ periods.
