Ask some people and most of them will say yes. "Pay-for-knowledge" has been more and more fashionable these years. The contents of these "pay-for-knowledge" products are from language learning to gardening or baby-caring. Everything you think of can be found online at this moment. "Pay-for-knowledge" is on the rise（兴起）.Why is "pay-for-knowledge" industry developing so rapidly? First, its development is based on the Internet. With a fast network and a smartphone, anyone who has passed the identity （身份）check can be an online teacher, and anyone with an online account can buy "pay-for-knowledge" products that he or she wants at an affordable price. Second, people are afraid to miss any information. On one hand, people hope for more useful information.On the other hand, such information is usually at the hands of experts（专家）whoserve well-known companies and universities. Moreover, the need to learn new skills in today's job market also pushes people to learn on such educational podcasts.The industry of "pay-for-knowledge" has proved to be lucrative. It promises possibilities of turning information into money. It is good for the development of our country and it can help sellers make lots of money. Besides, buyers can enjoy self-growth from it. What's more, this is a reflection（反映）of respect for knowledge and talents.However, the rapid development of "pay-for-knowledge" has a few problems. For one thing,the market is full of eye-catching words such as "How to be an Industry's Expert in 5 Hours" and "15 Classes to Be a Master of Appreciating（欣赏）Classical Music", which sound like if you pay for it, you are sure to succeed. For another, a large number of customers buy them just for showing off. In fact, those who have really had self-growth after buying online courses may be the kind of people who need them least. In other words, with or without these courses, they can make it anyway, because they are those who have the ability to learn by themselves.In general, the best is the one that suits you most. "Pay-for-knowledge" may be used asa good start for self-growth. Be careful! Otherwise, your dream of success may not come true.（1）Which of the following is TRUE according to the passage?A "Pay-for-knowledge" products can help all the people succeed.B People must learn from experts who serve famous companies and universities.C People who can teach themselves need "pay-for-knowledge" products most.D "Pay-for-knowledge" products can offer people different kinds of courses.（2）What can we learn about "pay-for-knowledge" industry from Paragraph 2?A The history of its development.B The problems of its products.C The causes of its rise.D The advantages of itsproducts.（3）The underlined phrase "be lucrative" in Paragraph 3 means "________".A enjoy self-growthB get much informationC win great respectD produce lots of money（4）The main purpose of this passage is to ________.A remind people to choose "pay-for-knowledge" products wiselyB advise everyone to learn knowledge by themselves onlineC recommend the "pay-for-knowledge" products to peopleD teach parents how to buy some online courses for their children19.When you're in school, the last thing you want to do is to work on weekends. There's homework to do, sports to play, fun to have. But our parents may persuade（劝说）us to find a job to earn money an get some life experience. When I was a teenager, I had to deliver the newspapers to people's homes. Then I got a Saturday job at a supermarket: putting everything in order on the shelves and working as a shopkeeper.Today in the UK you can work from the age of 13 and many children have part-time jobs. It is almost seen as an adult ceremony. It's an independent experience. Teenagers agreed that it taught them valuable lessons about working and managing money with adults. So that's not a bad thing!Some research suggests that not working on Saturdays or holidays may be harmful to one's later life. But recent statistics（数据统计）show 20% of the students have given up having part-time jobs in the past three years.So does this mean British teenagers are now more afraid of hard work? Probably not. Some experts believe young people feel that going out to work hinders（阻碍）their performance in school, they are now under more pressure（压力）to study hard, get good grades andhave a good job in the long run. However, proper part-time jobs are a great way to help young people learn the skills they need in the workplace. In fact, the key is to keep a balance between taking a part-time job and having enough time to study and rest.Many young people actually want to work because it gives them a sense of freedom. A 13-year-old girl named Rachel works in a shop on Saturday. She told the BBC: I like my job because I'm making money and it helps me to talk to people confidently and work with others closely. It seems like a valuable thing to do on a Saturday morning.（1）When I was a teenager, I ________ at first.A had too much homework to doB played sports with my good friendsC delivered food to people's homesD had a part-time job on Saturday（2）What makes some students give up part-time jobs?A They are now more afraid of hard work.B Taking part-time jobs may be harmful to their later life.C Going out to work hinders their performance in school.D Taking part-time jobs isn't a great way to help them learn skills.（3）Rachel likes her part-time job because ________.① She can make some money.② She can get good grades.③ It helps her talk with people confidently.④ It helps her get away from pressure.A ①②B ③④C ①③D ②④（4）The writer's purpose in writing the passage is ________.A To introduce his own part-time job experience.B To encourage students to take apart-time job. C To tell students how to keep a balance between study and jobs. D To make a survey on part-time jobs.20.Many people complain about their bad memory, especially when they are older. How can we improve our memory?Many people think that repeating things is the best way to remember them. While this undoubtedly helps short-term memory (remembering a telephone number for a few seconds, for example), psychologists（心理学家）doubt whether it can help you remember things for very long. The British psychologist E. C. Stanford seemed to prove this point when he tested himself on five prayers（祈祷文）that he had read aloud every morning for over 25 years. He found that he could remember no more than three words of some of them! More helpful, especially for remembering numbers, is grouping the information. The following numbers would be impossible for most of us to remember: 1492178919931848. But look at them in chunks, and it becomes much easier: 1492 1789 1993 1848.According to experts, there are many ways of training your memory. Many of them involve forming a mental picture of the things to be memorized. One method, which may be useful in learning foreign languages, is to create a picture in your mind connected to a word you want to remember.Another method is to invent a story that includes all the things you want to remember. In experiments, people were asked to remember up to 120 words using this skill; when tested afterwards, on average, they were able to recall 90% of them!However, not all of us are interested in learning long lists of names and numbers just for fun. For those studying a large amount of information, psychologists suggest that the best way to form meaningful connections is to ask yourself lots of questions as you go along. So, for example, if you were reading about a particular disease, you would ask yourself questions like: "Do people get it from water?", "What parts of the body does it influence?" and so on. This is said to be far more effective than time spent "passively" reading and re-reading notes.（1）Which of the following is TRUE about repeating things according to the passage?A It helps short-term memory for sure.B It makes remembering thingsinteresting. C It helps to remember things for long. D It makes remembering prayers effortless.（2）The underlined word "chunks" in Paragraph 2 probably means "________".A detailsB turnsC groupsD lines（3）What can we infer from the passage?A Creating a picture is useful in learning Maths.B Inventing a prayer trains our memory quickly.C Remembering long numbers is easy for people.D Asking yourself questions activates the memory.（4）What's the writer's main purpose in writing this passage?A To complain that his memory is bad.B To recognize some memory problems.C To explain some memory experiments.D To share some ways of improving memory.四、词汇运用21. 根据句子意思填空（每空一词）。

重点词：生：生存发展。
句义：忧患(能激励人勤奋)使人生存发展，享受安乐使人委靡死亡。
6、问题设计及解答(1)文章讲的是造就人才和治理国家的问题，中心论点：生于忧患，死于安乐。
(2)文中第一段所举历史人物的共同特点：都是在经历了艰难困苦之后才成就了不平凡的事业。
第一段运用排比句式的作用是：非常有力的说明人才是在艰苦环境中造就的道理。
(3)第一段承上启下的句子：故天将降大任于是人也，其中“是人”指上述六人和与此相似的其他人。
(4)第二段讲客观条件对造就人才的作用，阐述的道理是：成就大业，必须先经受苦难磨练。
其中阐述在思想上磨练的句子是：苦其心志。
在行动上受磨练的句子是：饿其体肤，空乏其身，行拂乱其行为。

)“自古英雄多磨难”。
历许多仁人志士在与挫折斗争中作出了不平凡的业绩。
司马迁在遭受宫刑之后，发愤著书，写出了被鲁迅誉为“史家之绝唱，无韵之离骚”的名著《史记》。
音乐家贝多芬，一生遭遇的挫折是难以形容的。
他十七岁失去母亲，三十二岁耳聋，接着又陷入了失恋的痛苦之中。
对一个音乐家来说，这打击是多么的大啊!可贝多芬不消沉、不气馁，他在一封信中写道：“我要扼住命运的咽喉，它妄想使我屈服，这绝对办不到。
”他始终顽强地生活，艰难地创作，成为世界不朽的音乐家。
一、词语解释舜发于：被任用人恒过：犯过失。
傅说举于：被选拔衡于虑同“横”故天将降大任于是人也所以;责任，担子;这而后作：奋起苦其心志：使┅┅痛苦征于色：脸色劳其筋骨：使┅┅劳累发于声：吟咏叹息饿其体肤：使┅┅饥饿而后喻：了解空乏其身：使┅┅贫困法家拂士：同“弼”辅佐乱其所为：使┅┅错乱、扰乱入则：在里面。
指国内所以动心忍性：用来;使┅┅惊动;使┅┅坚韧;出则：在外面。
指国外曾益其所不能：增加。
曾同“增”二、翻译所以动心忍性，曾益其所不能用来使他的心惊动，使他的性情坚韧起来，以不断增长他的才干。
人恒过，然后能改人常犯过失，然后才能改正入则无法家拂士，出则无敌国外患者，国恒亡(一个国家)国内如果没有坚持法度和辅佐君王的贤士，国外没有敌国外患，这个国家就往往会导致灭亡。
然后知生于忧患，而死于安乐也这样，人们才会明白，因有忧患而得以生存，因沉迷安乐而衰亡。
三、中心内容孟子认为人才是艰苦环境造就的，有了艰苦环境的磨练，才能使人性格坚韧、顽强，才能担负重大的使命。
本文中心论点是“生于忧患，死于安乐。
1、本文的论点是什么?答：生于忧患，死于安乐2、在作者看来，一个人经受了艰难困苦的磨练，将会有怎样的益处?答：所以动心忍性，曾益其所不能。
3、文中由个人升华到国家，论证“死于安乐”的道理的句子是什么?答：入则无法家拂士，出则无敌国外患者，国恒亡。
(二)《鱼我所欲也》《孟子》一、生字箪(dān)蹴(cù)羹(gēng)死亦我所恶(wù)二、重点词解释1、本心：天性，天良”2、患：祸患，灾难3、辟：通“避”，躲避4、箪：古代盛饭用的圆竹器。
5、蹴：用脚踢。
6、得：通“德”，恩惠，这里是“感激”的意思7、乡：通“向”，从前8、何加，有什么好处。
9、恶：厌恶。
10、辩：通“辨”，辨别。
11、义：正义或仁义。
12、勿丧：不丢掉，丧：遗失13、万钟：这里指高位厚禄14、贤者：有道德的人。
15、苟得：苟且取得，本文指：“苟且偷生，意思是只为求利益，不择手段。
三、重点句子翻译1、非独贤者有是心也，人皆有之，贤者能勿丧尔。
不仅有道德的人有这种信念，而且人人都有，只是有道德的人能不丧失罢了。
2、万钟则不辩礼义而受之，万钟与我何加焉。
对于优厚的俸禄如果不问他合不合礼义，就接受它，那么优厚的俸禄对我来说有什么益处呢?3、二者不可得兼，舍生而取义者也。
如果这两种东西不能同时得到，那么我就舍弃生命而选取正义了。
4、乡为身死而不受，今为所识穷乏者得我而为之。
以前为了礼义宁肯死亡，也不接受，今天却为了我所认识的穷苦人感激自己而接受它。
5、如使人之所欲莫甚于生，则凡可以得生者何不用也?假使人们追求的东西没有比生命更宝贵的，那么一切能够用来逃避祸患的手段，有哪一种不能采用呢?四、思考题1、本文出自《孟子?告子上》，作者孟子，战国时期鲁国人，思想家、教育家，是儒家思想的代表人物。
还学过他的文章有《得到多助，失道寡助》《生于忧患，死于安乐》(附“四书”：《孟子》《论语》《大学》《中庸》)2、归纳段意：第一段：论述舍生取义是人的本性。
第二段：论述见利忘义是丧失本性的行为。
(第一层(1-2句)从正面举例，说明义的存在。
第二层从反面举例，接受万钟这是丧失人的本性。
)3、理解及背诵：(1)本文的中心论点是什么?用原文回答：生，亦我所欲也;义，亦我所欲也，二者不可得兼，舍生而取义者也。
(2)文中能概括全篇大意的句子是：生，亦无所欲也，义，亦我所欲也;二者不可得兼，舍生而取义者也。
开头以“鱼”和“熊掌”为喻，巧妙地回答了这个问题，请写出原句：鱼，我所欲也，熊掌，亦我所欲也;二者不可得兼，舍鱼而取熊掌者也。
(3)《鱼我所欲也》中出现的成语有：舍生取义、嗟来之食;由此我们可联想到与本文观点相关的孟子曾说过的三句话：富贵不能淫，贫贱不能移，威武不能屈。
(4)《鱼我所欲也》中体现“性本善”思想的句子是：非独贤者有是心也，人皆有之，贤者能勿丧耳。
(5)孟子认为能做到舍生取义的人是：所欲有甚于生者，所恶有甚于死者(6)孟子认为失其本心的行为是：万钟则不辩礼义而受之(为宫室之美而受之;为妻妾之奉受之;为所识穷乏者得我而为之)。
