When I was 8, a gentleman came to my orphanage（孤儿院）and taught us how to do woodworking projects.

I remember my first project—a small table. I was so 36 of it that I looked upon it as if I had created a(an) 37 . It was absolutely beautiful and it had taken me six weeks to 38 it.

I could hardly wait to give it to Mother Winters as a 39 . She was the head mistress of our orphanage, who was always 40 with us.

As the tables were not dry from the clear coating, the man told us to wait a few days before taking them to our dormitories. But I was just so 41 and happy that I couldn?t wait. I dashed out like a 42 , carrying my table, smiling from ear to ear.

When I reached the dormitory I placed the little table beside my bed. I was 43 it when Mother Winters entered. She walked over to the table. Running her hand 44 it, she noticed that it was still wet.

“Were you 45 to bring this home?” she asked.

“No, ma?am,” I 46 with my head down.

She ordered me to throw the table out and so I did. After she left, I immediately opened the door to get it back. There was 47 stuck all over. I brushed and cried, but it would not come off.

I hid the table in my closet and never 48 it. A year later while cleaning up, I gave the table to Mother Henderson, my houseparent（宿管员）, thinking that she would 49 it away.

Thirty years later at a reunion, I 50 that Mother Henderson was living nearby, so I drove up to see her. We talked cheerfully for long. As I was about to leave, she asked me to come

第三部分：阅读理解（共两节，40分）

第一节（共15小题；每小题2分，共30分）

阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项，并在答题卡上将该项涂黑。

A

When the swim season began, my 11-year-old daughter, Elizabeth, and I cut a deal. She would go to practice three times a week and try really hard, and I wouldn?t make her compete in the swim meets because on the day of a meet, she would be nervous all day. Her nerves rooted from the possibility that she would do something horribly wrong and let everyone down.

Recently, they had a T-shirt relay, which works like this: one person from each relay team puts on a T-shirt and a pair of socks, swims 50 meters, and gets out of the pool. She takes off the clothes and puts them on the next person, who then swims 50 meters. This continues until everyone on the team has completed a lap.

By the last leg, Elizabeth?s team had built up a moderate lead. Then it was Elizabeth?s turn to swim. She seemed to swim faster in the T-shirt and socks than when she wasn?t wearing them.

Approaching the ha lfway mark, she was still in the lead. Then one of Elizabeth?s socks fell off and was floating in the pool. “She has to get that sock on before the end of the race,” a swimming official told her team, “or you will be disqualified.”

Everybody on her team st arted screaming, “Elizabeth! Elizabeth! Stop! Get the sock!” But she couldn?t hear them. As she started her last 25 meters, a girl in Lane 2 was gaining on Elizabeth. It was time for desperate measures. A girl on my daughter?s team jumped in the pool, grab bed the sock, and swam after Elizabeth. She grabbed Elizabeth?s foot. “You have to put the sock on,” the

girl screamed. Elizabeth continued swimming while her teammate put on the sock.

By now, the girl in Lane 2 was about to pass Elizabeth. With the sock finally on, Elizabeth swam her heart out for the last 15 meters. It was close, but Elizabeth beat the other girl to the wall for the victory.

On the ride home, she relived her moment of glory again and again. She told me that if the T-shirt relay was an Olympic event, her team would win the gold medal. I told her that in my professional opinion, she was absolutely right.

【小题1】Elizabeth was nervous about swim meets because she _______.

A. was afraid of disappointing everyone

B. didn?t expect to lose the sw im match

C. didn?t want to compete against other girls

D. was worried about making errors in public

【小题2】From the passage, we know that _______.

A. socks contributed greatly to Elizabeth?s victory

B. the match nearly drove Elizabeth desperate

C. good luc k finally fell on Elizabeth?s team

D. Elizabeth?s team narrowly won the match

【小题3】It can be inferred that Elizabeth would _______.

A. swim faster in the T-shirt

B. enjoy swim meets later on

C. experience the moment again

D. take part in an Olympic event

B

Expensive and new gloves allow chatterboxes（话匣子）to take the term “handsfree” to a new level—by talking into them as they make a call. The gloves

are known as “Talk to the Hand” and cost ￡1,000 a pair. They fixed a speaker

unit into the thumb and a microphone into the little finger that can be connected

to any mobile handset using Bluetooth.

Artist Sean Miles designed the new gloves that double as a phone in part of his project that shows the possibilities of gadget recycling. He uses outdated gloves and combines them with parts from mobile handsets recycled through O2, which commissioned（承担）the project. Mobile phone users will be able to keep their hands warm while they chat without taking their phones out of their pockets or handbags.

Mr Miles designed two pairs of the new gloves—one in pink and the other in brown and yellow. They will appear in an exhibition this July and visitors will be able to win the gloves. If demand is high, they will then be produced on a larger scale. O2 Recycle, which backed the project, estimates that there are already 70 million unused mobile handsets in the UK. The service pays up to ￡260 to those who recycle gadgets including phones, handheld consoles, MP3 players and digital cameras.

Designer Sean Miles hopes his work will get people thinking about recycling. The 41-year-old said, “I hope that my …Talk to the Hand? project will get people to think again about

the waste created by not recycling gadgets. If a few more people recycle their gadgets rather than send them to tr ash, I think this project will have fulfilled its aim.”

Bill Eyres, head of O2 Recycle, urges people to recycle their phone responsibly. He said, “There?s a pressing need for all of us to look at outdated handsets, and all the gadgets that we move on from or upgrade each year. Whether they are consoles or cameras, we should think of them as a resource that we need to recycle responsibly rather than throw them away.”

【小题1】The underlined word “O2” in Paragraph 2 is probably the name of ______.

A. an artist

B. a company

C. a mobile

D. an exhibition

【小题2】Consumers can buy the “Talk to the Hand” gloves ______.

A. in the exhibition

B. from Mr Miles

C. when they are mass produced

D. after they recycle the gadgets

【小题3】The purpose of the project is to _______.

A. promote the technology of IT

B. enable people to talk to their hands

C. raise people?s awareness of recycling

D. attract visitors? attention in the exhibition

【小题4】What is the passage mainly about?

A. New mobiles that are fashionable.

B. Outdated handsets that are upgraded.

C. Outdated gadgets that can be used for recycling.

D. New gloves that can be used for making phone calls.

For decades, families settled on the sofa to share the latest news and TV series, until additional bedroom TV, computer games and the Internet almost put an end to family rows over who held the remote control. Now, however, the traditional living room scene is making a comeback. A study by the communications watchdog Ofcom has found families are once again gathering around the main television set, but they are bringing their pads and smartphones with them.

“The 1950s living room is making a comeback as a family entertainment centre,” said Jane Rumble, head of media research at Ofcom. “We are watching on much better, bigger, and more delicate television sets, but we are coming into the living room holding our connected devices.” While the family are coming together once more, comparisons with the past end there. With a range of smaller screens on hand, not everyone sitting on the sofa shares the same viewing experience.

The coronation (加冕礼) may have drawn the undivided attention of 20 million viewers in 1953, but those watching the Queen?s Jubilee celebration s 50 years later were as likely to be

commenting online about BBC?s broadcast as watching it. “Just a few years ago, we would be talking about last night?s TV at work or at school,” said a viewer, “Now, we?re having those conversations live while watching TV, using social media, text and instant messaging.”

It is a behaviour of media meshing（联网）, whose influence was underlined during this year?s Wimbledon men?s tennis final. As Andy Murray pushed towards his victory, 1.1 million people worldwide sent an average of over two microblogs about the match.

People use the Internet to enhance their television experience, for example, by reading a newspaper live blog about a football match while watching the action on the main screen. For a huge number of younger viewers, the portable screen offers a chance to do something unrelated, such as online shopping, listening to music or watching another television programme.

Some 70% of 16-to-24-year-olds claim to be absorbed in what Ofcom calls “media stacking” at least once a week. For TV viewers, the Internet scanning is the most popular activity, but they are also calling friends on the phone or sending emails and texts. Surprisingly, 12% claim to have listened to the radio with the television on, and 6% say they have watched another video in the meanwhile.

【小题1】According to the study by Ofcom, family members nowadays _______.

A. care more about who holds the remote control

B. share the same programmes in the living room

C. watch better and more delicate television programmes

D. enjoy TV together with various smaller screens on hand

【小题2】This year?s Wimbledon men?s tennis final is mentioned to indicate _______.

A. so many people worldwide are watching TV

B. people like watching live matches on TV

C. the great influence of media meshing

D. the average amount of microblogs

【小题3】Which shows the phenomenon of “media stacking” in the last paragraph?

A. People are watching TV while shopping online.

B. People are watching a broadcast of a coronation.

C. The Internet makes people spend less time on TV.

D. The Internet enriches people?s television experience.

【小题4】The passage is written to _______.

A. describe the changes connected devices bring to TV watching

B. report the comeback of the traditional living room scene

C. show the influence of connected devices on people

D. present the different roles TV plays in people?s life

In her new book, “The Smartest Kids in the World,” Amanda Ripley, an investigative journalist, tells the story of Tom, a high-school student from Gettysburg, Pennsylvania, who decides to spend his senior year in Wroclaw, Poland. Poland is a surprising educational success

story: in the past decade, the country raised students? test scores from significantly below average to well above it. Polish kids have now outscored American kids in math and science, even though Poland spends, on average, less than half as much per student as the United States does. One of the most striking differences between the high school Tom attended in Gettysburg and the one he ends up at in Wroclaw is that the latter has no football team, or, for that matter, teams of any kind.

That American high schools lavish more time and money on sports than on math is an old complaint. This is not a matter of how any given student who plays sports does in school, but of the culture and its priorities. This December, when the latest Program for International Student Assessment(PISA) results are announced, it?s safe to predict that American high-school students will once again display their limited skills in math and reading, outscored not just by students in Poland but also by students in places like South Korea, Belgium, the Netherlands, Finland, Singapore, and Japan. Meanwhile, they will have played some very exciting football games, which will have been breathlessly written up in their hometown papers.

Why does this situation continue? Well, for one thing, kids like it. And for another, according to Ripley, parents seem to like the arrangement, too. She describes a tour she took of a school in Washington D.C., which costs thirty thousand dollars a year. The tour leader—a mother with three children in the school—was asked about the school?s flaws. When she said that the math program was weak, none of the parents taking the tour reacted. When she said that the football program was weak, the parents suddenly became concerned. “Really?” one of them asked worriedly, “What do you mean?”

One of the ironies of the situation is that sports reveal what is possible. American kids? per formance on the field shows just how well they can do when expectations are high. It?s too bad that their test scores show the same thing.

【小题1】Tom decides to spend his senior year in Poland because _______.

A. he intends to improve his scores

B. Polish kids are better at learning

C. sports are not supported at schools in Gettysburg

D. there are striking differences between the 2 countries

【小题2】According to Paragraph 2, we know that _______.

A. PISA plays a very important role in America

B. little time is spent on sports in Japanese schools

C. American high schools complain about sports time

D. too much importance is placed on sports in America

【小题3】The underlined sentence in the last paragraph means _______.

A. low expectations result in American students? poor PISA performance

B. high expectations push up American students? academic performance

C. American students? academic performance worries their parents a lot

D. lacking practice contributes to American students? average pe rformance 【小题4】The purpose of this article is to _______.

A. compare Polish schools with those in America

B. call on American schools to learn from the Polish model

C. draw public attention to a weakness in American school tradition

D. explain what is wrong with American schools and provide solutions

高三生物期中考试质量分析

高三生物期中考试质量分析 一、试卷分析 本次考试采用与高考相同的模式，实行理综考试。生物部分满分90分，考查范围是全部高考内容。试题各方面均衡，以中等难度的题目为主。试题特点如下： 1、考查高中生物全部内容，主要知识点均已覆盖。 2、重视基础知识和分析能力的考查。 3、信息明确，考点突出。 4、体现了一定的实验能力考查。 生物整体考试情况如下： 生物部分各题平均分和得分率如下： 试卷中错误率比较高的试题有：选择题1、3题，得分率在0.6左右或低于0.6。填空题29题、31题、32题,得分率在0.5以下。

二、成绩分析 本次生物一本线划线为62分，本校生物过线314人，目标生过入围线236人。跟高二阶段的考情相比，整体稳中略有升。但不能掉以轻心，仍要分析问题，找出薄弱题目的原因，充实后阶段的复习备考。 联考的三个学校对比： 我校的生物入围人数分析： 生物各分数段分析： 三、存在的问题 1、基础知识掌握情况不佳

很多学生仍存在着简单题得不到分的情况，在理综中选择题一题6分的情况下，基础知识的掌握不牢必然将会进一步放大，形成梯度式落差。基础知识的全面巩固仍然是一轮复习的重中之重。 2、理综试卷的时间规划不够合理 生物的分值为90分，但很多学生花了大量的时间在其他科目上，部分学生在生物上的用时仅有不到30分钟，甚至仅有十几分钟，在这么短的时间里，不仅中等难度的题目做不出来，简单的题目也是随意做，得分率极低。生物的时间要保证有40分钟，才能拿到应得的分数，时间太少必然影响生物的考试质量。 3、高三生物老师跨年级代课对备考有影响 本届全体高三老师都在高一年级跨年级代课，任务繁重。一个人的精力毕竟有限，跨年级代课的情况，或多或少影响了高三生物的复习备考。 四、改进的措施 1、增强基础知识复习的实效 （1）利用好现有的早自习读背活动，全面增强生物基础知识的背记。 （2）利用好培补手段，力促临界生的提升。培补的内容要集体讨论，形成有价值的训练题，培补的学生要面批面改，
