I stood in a noisy group of sixth grade students, waiting for the answer to our burning question: What type of crazy tie would Mr. Miller be wearing today?
Our teacher walked around the comer with a GREEN ELEPHANT TIE that matched his large elephant coffee cup! Oh, the satisfaction in our young hearts—a green elephant tie!
With his glasses at the tip of his nose, he greeted us cheerfully, “Good morning, folks!” He was strange and unique and he brightened every day for us. He was the most dynamic teacher I had ever met.
I loved music, so I remember how excited I was when he said he was going to give us music lessons. But when he turned on the music, my classmates and I slowly turned our heads toward
the sound of… Peter Paul and Mar y singing “If I Had a Hammer”.
Snickers (窃笑) fil led the room. If it wasn’t rap or hip hop, we didn’t recognize i t. What were these people singing about? My classmates were not into this at all. Rut for me, a girl of 12, it was a discovery. An awakening.
Twenty years passed and now there are forty little eyes staring at my wild musical-note shirts as I greet them with a joyful, “Good morning, class!” I wonder if my students wait und wonder what crazy music clothes I will wear each day.
I glance al my 2015 Teacher of the Year Award, which I received for being a dynamic teacher And I smile to myself, wondering which child in front of me will carry this on—as I’ve carried on the legacy (遗产) of Mr. Miller.
One teacher, who dared to be different and open new worlds to kids like me, threw the significant stone into the pond of my life. I pray the ripples (涟漪) never end.
24. What can we infer about Mr. Miller?
A. He was an animal lover.
B. He didn’t take his work seriously.
C. He often dressed up in an unusual way.
D. He often asked his students burning questions.
25. How did t he author react to the song “If I Had a Hammer”？

C. Uninterested.
D. Excited.
26. What does the underlined word “this” in the text refer to?

27. What is the author’s purpose in writing this text?

To fight for the conservation of forest ecosystem, several ecologists including Daniel Janzen convinced Del Oro, an orange juice producer, to donate part of their forestland to a national park. In return, Del Oro was allowed to throw large amounts of waste in the form of orange peels (皮)
on a 3-hectare piece of land within the national park at no cost. Dealing with tons of leftover peels usually involved burning them or paying to have them poured into a landfill, so the proposal was very attractive.
But a year later, another juice company challenged the deal in court, arguing that their competitor was “polluting a national park”. They ended up winning, an d the deal between Del Oro and the national park fell through.
Then in 2013, while discussing possible research avenues with Timothy Treuer, Daniel Janzen mentioned the orange story. Feeling interested, Treuer decided to stop by that piece of land that had been covered with fruit waste 15 years earlier. What he found shocked him.
“While I would walk over exposed rock and dead grass in the nearby fields, I d have to climb through undergrowth and cut paths through walls of vines (藤) in the orange peel site itself, said Timothy Treuer.
Treuer and his team spent months picking up samples (样品), analyzing and comparing them. They found great differences between the areas covered with orange peels and those that were not. The area with orange waste had richer soil.
The effect that the orange peels had on the land is probably not that surprising to people familiar with composting (施肥), but what is really shocking is that a judge actually thought the waste of orange “mined” a national park and slopped it from going fo rward. Now that Timothy Treuer’s study has rece ived worldwide attention, this type of “ruining” is being seriously considered as a way of bringing forests back to life.
28. What did Del Oro usually do with orange peels?
A. Add them to fuel.
B. Feed them to animals.
C. Bum or bury them.
D. Make them into cakes.
29. What can we know about the deal between Del Oro and the national park?
A. It lasted 15 years.
B. It was signed by Treuer.
C. It was made in about 1998.
D. It was broken by Del Oro.
30. What was Treuer’s finding?
A. Orange peels contain much fibre.
B. Orange peels can make soil richer.
C. Orange peels rot away in a short time.
D. Orange waste ruined the national park.
31. What is the author’s attitude toward the jud ge mentioned in the last paragraph?
A. Disapproving.
B. Positive.
C. Worried.
D. Admirable.
D
In the mid-2000s, Waze Mobile co-founder Ehud Shabtai received a cutting-edge (尖端的) gift from girlfriend: a GPS. The expensive gift was supposed to be helpful. But straight out of the box, it was already out of date.
Shabtai, a coding enthusiast, had an immediate reaction to reinvent. Shabtai’s solution? To build an app. With 80 million monthly active users globally and nearly 400,000 superusers who function much like Wikipedia volunteer editors (editing maps rather than words), Waze Mobile caught the eye of Google as a revolutionary approach to navigation (导航).
Acquired by Google in 2013, Waze’s value mainly lies in its high rate of user involvement. Unlike traditional navigation apps that simply show directions, Waze asks its users to report accidents and other road conditions in real time, so other users can avoid the traffic by using an alternative route.
The goal behind Waze’s approach is an ambitious one: not just avoid traffic, but end it altogether. Waze is finding new ways to put its loyal and active user base to use to make that vision a reality, including a plan to make carpooling (拼车) cool.
To be sure, traffic jams are troubling people all over the world. Waze has been quietly ahead of the game for some time. In 2013, when Waze was just a small digital-mapping business with limited resources it had something Google Maps and other c ompetitors didn’t: richer GPS guidance thanks to its stream of live traffic reports from users.
These users were the basis of Shabtai’s plan to solve for his GPS device’s “silent” hardware: he grounded the app in software that could be perpetually updated by users, anywhere and anytime.
Waze Carpool is going straight to the heart of traffic jams, trying to get more drivers off the road and into carpools. The app has already connected tens of thousands of rideseekers with drivers willing to ferry them along a shared route, and that trend could be the answer to a traffic-free future.
32. What did Shabtai do when he found his girlfriend’s gift out of date?
A. He improved it.
B. He took it apart.
C. He put it away.
D. He used it anyway.
33. What sets Waze Mobile apart from traditional navigation apps?
A. It has the most users.
B. It can indicate directions.
C. It reports road conditions in real time.
D. Most users help edit its words.
34. What does the underlined word “p erpetua lly” in paragraph 6 probably mean?
A. Difficultly.
B. Carefully.
C. Greatly.
D. Constantly.
35. What is mainly talked about in the text?
A. The rise of carpooling.
B. An advanced navigation app.
C. The development of Google.
D. Traffic problems in the world.

Habits to Be a Highly Effective Student
Some students are ab le to get straight A’s a nd at the same time serve as the president of three clubs. However, some students struggle to keep their GPA (Grade-Point Average) above a 3.0. 36 Although it’s true th at everyone’s IQ is dif ferent, good study habits are very important. Here’re several habits you should adopt to get good grades.
37 If you haven’t had a planner (规划薄), get one. Many people use their computers and smartphones to make a schedule. The problem with that approach is that they are major distractions (分心的事物). Instead, get an old-fashioned paper and pen planner.
Create a weekly schedule. 38 Include time that will be spent eating, sleeping and doing anything not related to school work. That way you know exactly how much you can accomplish each day.
Take frequent, short breaks. Taking a break from studying for 15 minutes every hour will help keep you refreshed. 39 If you don’t take a break, you may find yourself daydreaming or even falling asleep. Take some time for some water, a snack or a quick chat with a friend.
Take care of yourself. During final exam week, it is common for students to fall behind on sleep and me als. Make sure you get a good night’s sleep and have regular meals. Studying while
hungry or sleepy is ineffective and will slow you down in the long run. Also try to make time for friends and family. 40
A. Keep things organized.
B. Keep away from your computers.
C. Of course, not everyone needs breaks.
D. Our brains are not meant to work for hours nonstop.
E. Having a good support system will help with all the stress.
F. And they seem to spend all of their time in studying.
G. Then under each day, make a list of things to do each hour.

Any type of hobby that you can think of can be found in Australia. The following are four top Australian pastimes. Fishing Fishing is probably one of the most popular free-time activities in Australia and many people love spending their free time waiting at the end of a rod for a fish to bite on their line. There is free public access to almost all beaches，canals and coasts，which means there are plenty of great places to fish. Surfing Another popular pastime of the Australians is surfing. Australia has a lot of beautiful surf spots，especially in Queensland. Queensland has some of the best surf beaches in the country such as Noosa Heads，Stradbroke Island，and Burleigh Heads，with the Gold Coast being the best known. —江苏省靖江市高三调研试卷 数 学 试 题(选物理方向) 第Ⅰ卷（必做题 共160分） 一、 填空题(每小题5分,14小题，共70分，把答案填在答题纸指定的横线上） 1.集合{3,2},{,},{2},a A B a b A B A B ====若则 ▲ ． 2.“1x >”是“2x x >”的 ▲ 条件． 3.在△ABC 中，若（a ＋b ＋c ）(b ＋c －a ）＝3bc ，则A 等于_____▲_______． 4.已知a >0，若平面内三点A （1，-a ），B （2，2a ），C （3，3a ）共线，则a =___▲____. 5.已知21F F 、为椭圆 19 252 2=+y x 的两个焦点，过1F 的直线交椭圆于A 、B 两点,若1222=+B F A F ，则AB =_____▲_______. 6.设双曲线 22 1916 x y -=的右顶点为A ，右焦点为F ．过点F 平行双曲线的一条渐近线的直线与双曲线交于点B ，则△AFB 的面积为 ▲ ． 7.已知t 为常数，函数22y x x t =--在区间[0，3]上的最大值为2，则t=____▲____. 8.已知点P 在抛物线2 4y x =上，那么点P 到点(21)Q -，的距离与点P 到抛物线焦点距离之和取得最小值时，点P 的坐标为________▲______. 9.如图，已知球O 点面上四点A 、B 、C 、D ，DA ⊥平面ABC ， AB ⊥BC ，DA=AB=BC=3，则球O 点体积等于_____▲______. 10.定义：区间)](,[2121x x x x <的长度为12x x -.已知函数| log |5.0x y =定义域为],[b a ，值域为]2,0[，则区间],[b a 的长度的最大值为 ▲ . 11.在平行四边形ABCD 中，AC 与BD 交于点O E ， 是线段OD 中点，AE 的延长线与CD 交于点F ．若AC =a ，BD =b ，则AF = _____ ▲_____. 12. 设 {} n a 是正项数列，其前n 项和n S 满足： 4(1)(3)n n n S a a =-+,则数列{}n a 的通项公式n a = ▲ . 13.若从点O 所作的两条射线OM 、ON 上分别有点1M 、2M 与点1N 、2N ，则三角形面积之比为： A B C D A2018深圳市高考英语模拟试题(3)(附答案)
