课时作业8Ⅰ.阅读理解(2019·济宁市高三摸底考试)Known worldwide for its unusual entertainment options, the Sun City theme park is more a mini­city than a park, with so many attractions and entertainment options that first­time visitors may find it pleasantly confusing.Located in the North West province, less than 200 kilometers from the major urban centres of Johannesburg and Pretoria, the Sun City entertainment park attracts all with its African theme and abundance of entertainment options. Far enough from the major cities of South Africa to qualify as a real getaway from busy city life, the Sun City is still the last all­in­one entertainment destination.Activities range from adventure sports and safari options to a world­famous golf course and a wide variety of rides and games to keep the children happily busy.Many will probably want to swing their clubs at the Gary Player Country Club, home to the world­famous Nedbank Golf Challenge. Others may want to relax in the sun poolside at the Valley of the Waves while the kids go screaming down one of the water park's many thrilling slides.Adults can try their luck at one of the biggest casinos (赌场) in Africa before taking in a comedy or live music show, or simply enjoy a meal at one of the many award­winning but reasonably priced restaurants. They can choose from Asian, traditional South African or Italian, or just order from one of the many fast food restaurants.Kamp Kwena, an activity park for children where they can learn, play and make new friends, will keep lively litt le minds well occupied. Mini­cars, adventure golf and more ensure that the kids don't miss their parents too much.The Sun City isn't just a hotel or an entertainment place or even just a theme park; it's an entire experience.本文主要介绍了南非的太阳城主题公园的相关信息。

AFor a long time, many people believed girls are at a disadvantage in the classroom, especially when it comes to some subjects，but the situation now in the classroom is d ifferent from that in the past. These days it seems that male students can't keep up with their female classmates.Richard Whitmire, an education reporter and author of Why Boys Fail, says that the problem starts early. There are two signs of the change: there are much more aspirations(渴望) in female students in high schools, but male students don't have many. We can easily find these examples in colleges. There are more female students than male students in colleges. The number of female students is larger than that of male students in recent years.What's behind the new change? There are a lot of reasons why boys fall behind in the classroom nowadays. Christina Hoff Sommers, writer of The War Against Boys, pointed out that classrooms were rebuilt to serve the needs of girls instead of boys. It is a dangerous action that has hurt boys. Less structured learning situations and less focus on marks and challenges are signs of a changing school. These will put boys in a harmful situation. Others consider that there are a lot of learning materials which boys are not interested in. The school lacks male teachers, and also many male students think they cannot have a good rest at school. So which of these is really behind the problem.In his book, Richard Whitmire says, there are a lot of reasons. However, he argues that some of these may be the reasons for the problem, but there's one that is holding boys back. “If you solve one important thing，” he says，“then you could solve the problem, and that is the literacy(读写能力) issue.”1．From Paragraph 1 we know that________．A．male students are always better than female studentsB．female students used to be lazy in the classroomC．male students often fall behind nowadaysD．female students were stronger in the past2．Which of the following is NOT true of the changing school?A．We can see fewer good female teachers in the school.[来源:学&科&网Z&X&X&K]B．The schools don't have a good learning situation for the boy.C．The schools pay less attention to marks and challenges.[来源:学#科#网Z#X#X#K]D．Classrooms tend to serve the needs of the female students.3．The purpose of the passage is mainly to________．A．tell people a new kind of schoolB．call on people to change the school situationC．tell people that female students are more importantD．explain why the schools need more male teachers4．In which column will you most probably read the article?A．Science.B．Education.C．Culture. D．News.语篇解读：近些年，我们经常听到这种声音：女生学习成绩越来越厉害了，男生明显有些落后。

We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about. The list goes on and on.Well, that_train_has_left_the_station. But can using the Internet too much be bad for our health? It might be, researchers say. A new study finds that heavy Internet use may be connected to high blood pressure(血压) in an unlikely group: teenagers.High blood pressure makes your heart and blood vessels (血管) work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause heart and kidney (肾脏) disease. It is also closely linked to a brain disease.The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people from 14 to 17 years old, took part in it. 134 of the teens were described as “heavy Internet users”. And researchers found that out of these 134 teens, 26 had high blood pressure.The lead researcher is Andrea Cassidy­Bushrow. She said, “Using the Internet is part of our daily life, but it shouldn't ruin us.” Ms Cassidy­Bushrow adds that it is important for teens to take regular breaks from their computers or smartphones and do some kind of physical activity. She also suggests that parents limit (限制) their children's use of the Internet to two hours a day, five days a week.1．The underlin ed expression “that train has left the station” in Para.2 is used to show ________.A．the Internet develops rapidlyB．no one can escape from the InternetC．the Internet can provide whatever we wantD．there is no going back to an Internet­free life2．What is Para.3 mainly about?A．Causes of high blood pressure.B．The harm of high blood pressure.C．The disadvantages of Internet use.D．Ways to prevent high blood pressure.3．Andrea Cassidy­Bushrow would agree that ________.A．teenagers shouldn't use the InternetB．the Internet will ruin human life in the futureC．smartphones are more harmful than computersD．regular breaks are necessary when using the Internet4．What can be used as the best title of the passage?A．Heavy Internet Users Are Mostly TeenagersB．How to Prevent Teenagers from the InternetC．Too Much Internet Use May Be Bad for TeenagersD．Every Coin Has Two Sides—So Does the Internet答案与解析本文是一篇说明文。
