There are hundreds of national parks and wildlife areas in Africa that you can travel to. Here are the top four travel destinations in Africa: Tanzania----Serengeti National Park During the annual migration , when the wildebeests and zebras pack up and leave their living areas to find fresher ones, the Serengeti is an astonishing place to be. It's a very good travel spot in Africa at other times of the year too, but the migration has been ranked by many as one of the wonders of the natural world. Kenya----Masai Mara National Park If you want to see the big cats, this wildlife park is the best of the best. Lion, leopard and cheetah abound and they are relatively easy to spot because of the grassland vegetation which means you get good views for miles around. Another big plus is the fact that going off road is allowed and it is a big advantage because the animals will rarely oblige you and stay next to the major roads. South Africa-Kruger National Park For the variety of species no other places in Africa can come close to the Kruger Park. And because it is so large it has a number of different ecosystems that you can pass through in your search for animals and birds. It is one of the best managed parks in Africa and the accommodation is well-equipped, too. Zambia-South Luangwa National Park South Luangwa is a diamond in the rough, just waiting for enough exposure to bring it to its rightful place in the crown of prime Africa trips. It has been regarded as one of the best places in Africa to see the special leopard and it is the birthplace of the walking travel. If you want to see wildlife on foot, you should go to _ . A) Serengeti National Park. B) Masai Mara National Park. C) Krunger National Park. D) South Luangwa National Park.

The old saying that practice makes perfect seems to make no sense when it comes to schoolwork. Many educators today are looking for evidence to support the case for homework, but are coming up empty-handed. Mary Jane Cera is the academic administrator for the Kino School, and she maintains a no-homework policy across all grades. The purpose of the policy is to make sure learning remains a joy, not a thing that discourages social time and creative activity. At the Kino school, Cera says children often choose to take their favorite parts of school home. "A lot of what we see kids doing is practicing music with their friends, and taking experiments home to show their parents," she says. Surveys of Kino graduates suggest that the early control they are given over their education continues to serve them well into college. "One of the reasons that we continue to assign much homework is our obsession with tests, although we can agree on the importance of kids doing better on tests through proper homework to some degree,"says author Alfie Kohn. In his book The Homework Myth, Kohn points out that no study has ever found a relation between homework and academic achievement and that if kids have no choice in the matter of homework, they're not really exercising judgment, and are instead losing their sense of self-control. However, many supporters of homework argue that life is filled with things we don't like to do, and that homework teaches self-discipline, time management and other non-academic life skills. Wherever the homework debate goes next, it's worth taking a moment to examine if we're doing the right thing about our children's education. The good news is -- it's never too late to start. What would Kohn probably agree with? A) Homework is linked to academic achievement. B) Homework can equip students with life skills. C) Homework leads to the loss of kids' creativity. D) Homework might improve kids' grades in exams.

Q: Ever feel like you've been hit on the head after a bad night's sleep? According to scientists, the thought isn't as unbelievable as it seems. A study found going without sleep for just one night causes changes in the brain similar to those that occur after a blow to the head. The researchers said the healthy young men examined in the study showed a sudden increase in the same chemicals which indicate brain damage. Professor Christian Benedict, of Uppsala University, Sweden, explained that the chemicals NSE and S-100B are biomarkers for brain damage, such as concussion . He said, "What we found was their levels in the blood rose in the group that went without sleep for a night. This was not to the extent that would happen after a head injury, for instance, but it was still significant. During sleep, the brain cleans poisonous substances off itself." Benedict also said previous studies which linked a lack of sleep with increased risk of Alzheimer's, Parkinson's and multiple sclerosis could applaud his study. The rise of the chemicals in the blood after sleep loss may suggest not getting enough sleep contributes to a loss of brain tissue, he explained. Benedict, whose study is published in the journalSleep, added, "In conclusion, the findings of our experiment indicate a good night's sleep may be critical to maintaining brain health." A third of the UK population suffer from sleep-related problems, while the average person now sleeps for only seven hours a night, compared with almost nine a few decades ago. Many scientists believe irregular sleeping patterns lead to illnesses ranging from aches and pains to heart disease, while less than eight hours' sleep a night can lower the IQ the next day. What do we know about previous studies? A) They found reasons for brain disorders. B) Their findings were published inSleep. C) They were supported by Benedict's study. D) They focused on brain health.

In prefix = st1 /America, drivers' education is part of regular high school curriculum. Every student in his or her second year of high school is required to take a class in driver's education. However, unlike other courses, it is not given during the regular school year. Instead, it is a summer course. The course is divided up into two parts: class time for learning laws and regulations and driving time to practise driving. Class time is not unlike any other class. The students have a text from which they study the basic laws they must know to pass the written driving test that is given to anyone wanting to get a driver's license. Driving time is a chance for the students to get behind the wheel (steering wheel) and practise starting steering, backing up, parking, switching lanes, turning corners, and all the other maneuvers required to drive a car. Each student is required to drive a total of six hours. The students are divided up into groups of four. The students and the instructor go out driving for two-hour blocks of time. Thus, each student gets half an hour driving time per outing. The instructor and "driver" sit in the front seats and the other three students sit in the back. Drivers Ed cars are unlike other cars in which they have two sets of brakes, one on the driver's side and one on the other side where the instructor sits. Thus, if the student driver should run into difficulties the instructor can take over. The car also has another special feature. On the top of the car is a sign that reads: STUDENT DRIVER. That lets nearby drivers know that they should use extra caution because the student driver is a beginning driver, not very experienced and prone to driving slowly. After the student has passed the driver's education course and reached the appropriate age to drive (this age differs in every state but in most cases the person must be 16 years old), they can go to a designated state office to take their driver's test, which is made up of an eye examination, a written test, and a road test. The... We can infer that the students are required to _ in their whole driving practice. A) go out driving for twelve times B) spend at least six hours driving C) drive for two-hour blocks of time D) get half an hour driving
