Tsunami is a Japanese word which means harbor wave and is used as the scientific term for seismic sea wave generated by an undersea earthquake or possibly an undersea landslide or volcanic eruption. When the ocean floor is tilted or offset during an earthquake, a set of waves is created similar to the concentric waves generated by an object dropped into the wave. Most tsunamis originate along the Ring of Fire, a zone of volcanoes and seismic activity, 32.500 km long that encircles the Pacific Ocean. Since 1819, about 40 tsunami have struck the Hawaiian Islands. A tsunami can have wave lengths, or widths, of 100 to 200 km, and may travel hundreds of kilometres across the deep ocean, reaching speeds of about 725 to 800 kilometres an hour. Upon entering shallow coastal waters, the wave, which may have been only about half a metre high out at sea, suddenly grows rapidly. When the wave reaches the shore, it may be 15 metres high or more. Tsunamis have tremendous energy because of the great volume of water affected. They are capable of obliterating coastal settlements. Tsunami should not be confused with storm surges, which are domes of water that rise underneath hurricanes or cyclones and cause extensive coastal flooding when the storms reach land. Storm surges are particularly devastating if they occur at high tide. A cyclone and accompanying storm surge killed an estimated 500,000 people in Bangladesh in 1970. The tsunami which truck south and southeast Asia in late 2004 killed over 200 thousand people.

People commonly complain that they never have enough time to accomplish tasks. The hours and minutes seem to slip away before many planned chores get done. According to time management experts, the main reason for this is that most people fail to set priorities about what to do first. They get tied down by trivial, time consuming matters and never complete the important ones. One simple solution often used by those at the top is to keep lists of tasks to be accomplished daily. These lists order jobs from most essential to least essential and are checked regularly through the day to assess progress. Not only is this an effective way to manage time, but also it serves to give individuals a much deserved sense of satisfaction over their achievements. People who do not keep lists often face the end of the word day with uncertainly over the significance of their accomplishments, which over time can contribute to serious problem in mental and physical health.

How to protect children Web fans from unsuitable material online while encouraging them to use the Internet has long been discussed in the US. For some parents, the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as hazard and with good guides, some education, and a few precautions, the wilds of the Internet can be safely navigated. “Kids have to be online. If we tell our kids they can’t be allowed to surf the Internet, we’re cutting them off from their future,” said an expert. Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way would be to use what is known as a “content screener”. But this can’t be wholly reliable, and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing the Internet. A few other tips as follows: Don’t put the PC in a child’s room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity. Ask your child what he or she has been doing and about any friends they make online. Tell your child not to give online strangers personal information, especially like address and phone number. And tell your children never to talk to anyone they meet on line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.

American movies create myths about college life in the United States. These stories are entertaining, but they are not true. You have to look beyond Hollywood movies to understand what college is really like. Thanks to the movies, many people believe that college students party and socialize more than they study. Movies almost never show students working hard in class or in the library. Instead, movies show them eating, talking, hanging out, or dancing to loud music at wild parties. While it is true that American students have the freedom to participate in activities, they also have academic responsibilities. In order to succeed, they have to attend classes and study hard. Another movie myth is that athletics is the only important extracurricular activity. In fact, there is a wide variety of nonacademic activities on campus such as special clubs, service organizations, art, and theater programs. This variety allows students to choose what interests them. Even more important, after graduation, students' résumés look better to employers if they list a few extracurricular activities. Most students in the movies can easily afford higher education. If only this were true! While it is true that some American college students are wealthy, most are from families with moderate incomes. Up to 80% of them get some type of financial aid. Students from middle and lower-income families often work part-time throughout their college years. There is one thing that many college students have in common, but it is not something you will see in the movies. They have parents who think higher education is a priority, a necessary and important part of their children's lives. Movies about college life usually have characters that are extreme in some way: super athletic, super intelligent, super wealthy, super glamorous, etc. Movies use these stereotypes, along with other myths of romance and adventure because audiences like going to movies that include these elements. Of course, real college students are not like movie characters at all. So the next time you want a taste of the college experience, do not go to the movies. Look at some college websites or brochures instead. Take a walk around your local college campus. Visit a few classes. True, you may not be able to see the same people or exciting action you will see in the movies, but you can be sure that there are plenty of academic adventures going on all around you.

According to the passage, why do many people never seem to have enough time to accomplish things?

Successful students often do the followings while studying. First they have an overview before reading. Next, they look for important information and pay greater attention to it (which often needs jumping forward or backward to process information). They also relate important points to one another. Also, they activate and use their prior knowledge. When they realize that their understanding is not good, they do not wait to change strategies. Last, they can monitor understanding and take action to correct or “ fix-up” mistakes in comprehension. Conversely, students with low academic achievement often demonstrate ineffective study skills. They tend to assume a passive role in learning and rely on others(e.g, teachers, parents) to monitor their studying. For example, low-achieving students often do not monitor their understanding of content, they may not be aware of the purpose of studying, and their show little evidence of looking back, or employing “fix-up” strategies to fix understanding problems. Students who struggle with learning new information seem to be unaware that they must extent beyond simply reading the content to understand and remember it. Children with learning disabilities do not plan and judge the quality off their studying. Their studying may be disorganized. Students with learning problems face challenges with personal organization as well. They often have difficulty keeping track of materials and assignments, following directions, and completing work on time. Unlike good student who employ a variety of study skills in a flexible yet purposeful manner, low-achieving students use a restricted range of skills. They can not explain why good study strategies are important for learning, and they tend to use the same, often ineffective, study approach for all learning tasks, ignoring task content, structure of difficulty.
