often：ability，money，and time. 16 Money is a topic I’ll save for another day.So today I want to give you some wisdom about how to make the most of the time you spend in the kitchen.Here are three tips for great cooking on a tight schedule：‎ ‎1．Think ahead.The moments when I think cooking is a pain are when I’m already hungry and there’s nothing ready to eat.So think ahead of the coming week.When will you have time to cook？Do you have the right materials already？ 17 ‎ ‎2．Make your time worth it.When you do find time to cook a meal，make the most of it and save yourself time later on.Are you making one loaf of bread？ 18 It takes around the same amount of time to make more of something.So save yourself the effort for a future meal.‎ ‎3． 19 This may surprise you，but one of the best tools for making cooking worth your time is experimentation.It gives you the chance to hit upon new ideas and recipes that can work well with your appetite and schedule.The more you learn and the more you try，the more ability you have to take control of your food and your schedule.‎ Hopefully that gives you a good start. 20 And don’t let a busy schedule discourage you from making some great changes in the way you eat and live!‎ A．Try new things.‎ B．Ability is easily improved.‎ C．Make three or four instead.‎ D．Understand your food better.‎ E．Cooking is a burden for many people.‎ F．Let cooking and living simply be a joy rather than a burden.‎ G．A little time planning ahead can save a lot of work later on.‎ 答案　16.B　17.G　18.C　19.A　20.F Ⅱ.写作常用句翻译 ‎1．这是给退休教师的多么好的礼物！(retire)(2012·广东·读写任务)‎ What a wonderful gift to a retired teacher!‎ ‎2．我也希望我的努力能得到回报。(pay off)(2011·山东·写作)‎ I also hope that the great effort I am making will pay off.‎ 模拟题组 Ⅰ.语法填空 ‎1．He was in poor health，so the doctor forbade

beautiful.(素材来源于2014·广东·读写任务)‎ As long as there is kindness and virtue，the world will become more beautiful.(用as long as改写 为复合句)‎ Ⅰ.阅读理解 A Improving your vocabulary can be done at any age and any level of education.Even college students can benefit from an enlarged vocabulary，which will enhance spoken and written communication as well as providing a deeper grasp of any language.Often people are encouraged to improve their vocabulary by a major test，but improving your vocabulary can be done for fun as well.Reading more，playing word games and puzzles，and looking up words in the dictionary are all good ways to learn new words.‎ One of the best ways to improve your vocabulary is to read more.Reading is directly linked with a larger vocabulary，especially if you seek out books in unfamiliar styles or about unfamiliar topics.Nonfiction in a wide variety of fields can teach you new words and general knowledge，but reading fiction is also highly beneficial.As you read，make a note of unfamiliar words，look them up，and write down the definition.‎ Playing word games is a fun way to learn new words.Games like Scrabble and Boggle will encourage your brain to play with words and letters，as well as learning new ones.If you play with an open dictionary，you can encourage people to try out words they might otherwise be afraid of using.Most word games are interactive，so you enjoy company while you expand your vocabulary.‎ Another way of improving your vocabulary is to do word puzzles.Most newspapers include crosswords，simple cryptology puzzles，and jumbles that get progressively harder throughout the week.Try to commit to completing all of the word puzzles every day，or at least attempt to finish them.Word puzzles can also be done in groups，especially if you enjoy competition.You can purchase books of word puzzles of varying difficulty for a different challenge.‎ A simple way to improve your vocabulary is to use the dictionary.Create flashcards of unfamiliar words and practice them in the train，on the bus，or when you wake up in the morning.Try to practice words in a variety of environments so that you really learn them，and make sure to use the words in daily sentences as well so that you can grow accustomed to using them correctly.If you hear someone using a word you don’t recognize，ask him or her about it or look it up.‎ ‎1．What does the underlined word “enhance” in Paragraph 1 probably mean?‎ A．Improve. B．Decrease.‎ C．Practice. D．Purchase 答案　A 解析　词义猜测题。根据上下文可知，此句话意思是：词汇量大对大学生非常有利，会提高他们口语和写作表达能力，也会帮助他们深层理解任何语言。故选A项。‎ ‎2．How many fun ways of improving vocabulary are mentioned in the passage?‎ A．3. B．4. C．5. D．6.‎ 答案　B 解析　细节理解题。文中一共提到4种有趣的扩大词汇量的方法：to read more，playing word games，to do word puzzles和to use the dictionary，故选B项。‎ ‎3．Which of the following is a word game?‎ A．Nonfiction. B．Boggle.‎ C．Jumbles. D．Crosswords.‎ 答案　B 解析　细节理解题。根据第三段中的“Games like Scrabble and Boggle will encourage your brain to play with words and letters，as well as learning new ones.”一句可得出答案，故选B项。‎ ‎4．What do we learn from the last two paragraphs?‎ A．You have to complete all of the word puzzles to improve your vocabulary.‎ B．Word puzzles sometimes are so difficult that they need to be done in groups.‎ C．Practicing words everywhere and using them in daily sentences are helpful.‎ D．You can ignore the new words used in the conversation with your friends.‎ 答案　C 解析　推理判断题。根据最后一段中的“Try to practice words in a variety of environments so that you really learn them，and make sure to use the words in daily sentences as well so that you can grow accustomed to using them correctly.”可知C项为答案。‎ B One winter term during college in northern New York，I took an 8 am history class to fulfill a requirement.It was hard to get up for that class，but about 15 of us met 3 times a week to face the cold winds bravely and go to that lecture in a classroom.‎ The professor for the class was a strange fellow.He had flaming red hair and usually wore rain boots with one leg of his pants in and the other out.He would walk shyly into the room wearing his hooded(带兜帽的)winter coat，once even not removing the hood during the lecture.He was terribly ill at ease with the class and held the lecture hardly looking up through his gold rimmed glasses at his students.‎ I felt that I needed to do something to stop the boredom that would follow in his lecture，so I created a little game for myself.I would find something in his lecture to ask him，forcing me to pay attention rather than letting my eyes close.The first time I raised my hand，he was surprised and a little unwilling to find out what I wanted.But he was obviously pleased to have a question to ‎ answer.In fact，his answers were always interesting.‎ I continued to do this in class and found myself actually enjoying the material.The professor seemed to become a bit more relaxed and some of the other students even joined in from time to time.My little game had saved me from being bored as it was designed to do.And，I learned quite a bit about ancient world history in the bargain.The professor obviously knew his material，but he had a hard time passing it on to students in an interesting way.For all his strange appearance，he was indeed quite an expert in his field.‎ But the real lesson I was to learn had yet to happen.On the last day of the class we gathered our books and headed out of the door for the last time.The shy，redhaired professor stepped directly in front of me and put out his hand.“I want to thank you for making this class so interesting，” he said，shaking my hand firmly and smiling for the first time.I was so surprised.To me，it had been a pleasant way to pass the time in an optional course.I had no idea that all of my questions had any effect on him or the others at all.‎ That moment has stayed with me for 30 years.Each of us，through the things we say and do，the kindnesses we can freely offer，can have a deep effect not just on our own experiences，but those of others.I don’t recall the facts I learned in his class，but I’ll never forget the professor who taught me a lesson about the power of acts of kindness，intended or not.‎ ‎5．The author chose to take history class probably because .‎ A．it was easy to learn B．he majored in history C．it was his favorite course D．he needed it to finish college 答案　D 解析　推理判断题。第一段中说选历史课是为了完成一项要求，第五段倒数第二句中又说这是选修课，由此可以推知这是作者要完成大学学业所选修的课程。‎ ‎6．The author always asked questions in class in order to .‎ A．show off his cleverness B．keep himself concentrating on the class C．leave the professor with a deep impression D．make the teacher embarrassed 答案　B 解析　细节理解题。第三段前半部分说教授的课很乏味，为了防止自己睡着，更为了使自己集中注意力，所以作者才想出这个办法。‎ ‎7．We can learn from the fourth paragraph that .‎ A．most students weren’t satisfied with the professor B．the professor’s classes were always badly organized C．the professor tried hard to make his classes interesting D．the author gained a lot of history knowledge in this course 答案　D 解析　细节理解题。由第四段中的倒数第三四“And，I learned quite a bit about ancient world history in the bargain.”可知作者在教授的课上学到了很多世界古代史的知识。‎ ‎8．Why did the professor thank the author on the last day of the class?‎ A．Because the author pointed out some faults in his lectures.‎ B．Because the author gave him some advice on his teaching.‎ C．Because the author brought fun and liveliness to his lectures.‎ D．Because the author had a high opinion of his teaching.‎ 答案　C 解析　细节理解题。由第五段中教授对作者所说的话可知，作者在课堂上的提问使教授的课变得生动有趣起来，所以教授想要感谢作者。‎ Ⅱ.阅读填空 You already know an environmentalist’s three R’s：reduce，reuse，recycle. 9 Here are three things you can do for Earth Day.‎ ‎•Be a real cutup The next time you’re about to throw out the plastic rings that hold a sixpack of soda together, reach for a pair of scissors.‎ As a young turtle，Peanut got stuck in one of those rings.As she grew，the ring stayed put，forcing her shell to grow around it.By the time someone found her and cut her free，her shell was permanently deformed(使成畸形)． 10 She now lives at a nature center in Missouri.But most animals that get caught in sixpack rings die.‎ WHAT YOU CAN DO Easy！Cut the rings apart before you trash them.‎ ‎•Hunt for vampires(吸血鬼)‎ You know all those electronic inventions

the plugs or tap the OFF switch till you really need the electronics.‎ ‎• 12 ‎ Matt Damon really cares about clean water.So in February，he announced that he was going on strike—against toilets.“Until everybody has access to clean water and sanitation，”he said，“I ‎ will not go to the bathroom！”He was kidding—but to make a serious point.Around the world，he said，“780 million people lack access to clean water；2.5 billion people lack access to a toilet.”‎ WHAT YOU CAN DO ‎ 13 Just don’t waste water.Don’t run the water while brushing your teeth.Take shorter showers.‎ A．Get water wise B．Use toilets less C．But how else can you help?‎ D．No need to go on a toilet strike.‎ E．How to recognize vampire electronics?‎ F．That’s twice the population of the United States.‎ G．Thanks to her hard
