“I can’t concentrate.” “My mind wanders when I try to study.” Lack of concentration is one of the most common complaints heard at school.
We all have the ability to concentrate. Think of the times when you were attracted to a super novel or the times when you were playing your guitar or piano. But at other times your mind races from one thing to another. Here are some tips.
Rest from time to time. Remember to take short breaks. Lectures are usually 50 minutes long, and that’s about the length of time most people can direct their attention to one task. But that’s just an average. Your concentration time might be shorter (20-35 minutes) or longer (perhaps 90 minutes).When you take a break, you get more oxygen to your brain! When we sit for long periods, blood tends to be pooled in our lower body and legs. Get up and walk around the room for a couple of minutes. As a result, more oxygen is carried to the brain and you can concentrate better.
_______________If you study one subject for a long time, you may find it hard to concentrate. Many students improve their concentration by changing one subject to another every one to two hours. In this way you can pay more attention to something that’s different.
Reward yourself. Give yourself a reward when you’ve completed a task. The task might be small, such as staying with a difficult paper until you’ve finished. But giving yourself a reward can help you be more interested in doing other tasks.
Increase your activity level. Your concentration wanders more easily if you just read an article straight through. Instead, take the heading for each part and turn it into a question. For this part, that would be, “How can I increase my activity level while studying?” Then study that part to answer that question. Do this routinely. The questions give us a focus for each part and increase our involvement(參與).
小題1:According to Paragraph 3, what’s the purpose of walking around?
A．To help us stay fit.
B．To benefit our lower body.
C．To provide the brain with more oxygen.
D．To increase our concentration time to 90 minutes.
小題2:What’s the best title for Paragraph 4?
A．Study for one hour each time.
B．Do something difficult.
C．Study in different ways.
D．Change subjects.
小題3:In the last paragraph, the writer suggests that______.
A．we just read the heading of some articles
B．we do our best to read an article straight through
C．we ask ourselves questions about what we are reading
D．we ask other people questions about the article we are reading
小題4:The writer wrote the passage to______.
A．encourage us to try to concentrate

      Sometime in the next century, the familiar early-newspaper on the front porch (門廊) will  disappear. And instead of reading your newspaper, it will read to you. You'll get up and turn on  the computer newspaper just like switching on the TV An electronic voice will distribute stories  about the latest events, guided by a program that selects the type of news you want. You'll even get to choose the kind of voice you want to hear. Want more information on this brief story? A simple touch makes the entire text appear. Save it in your own personal computer if you like. These are among the predictions from communication experts working on the newspapers of the future. Pictured as part of broader home-based media and entertainment systems, computer newspapers will unite print and broadcast reporting, and offer news and analysis with video images of news events.
Most of the technology is available now, but convincing more people that they don't need to  read a newspaper is the next step. But resistance to computer newspapers may be stronger from  within journalism. Since it is such a cultural change, it may be that the present generation of  journalists and publishers will have to die off before the next generation realizes that the  newspaper industry is no longer a newspaper industry. Technology is making the end of ' traditional newspapers unavoidable.
Despite technological advances, it could take decades to replace newsprint with computer  screens. It might take 30 t0 40 years to complete the changeover because people need to buy  computers and because newspapers have established financial interests in the paper industry.

An alcohol breath test (ABT) is often used by the police to find out whether a person is drunk while driving.In the United States，the legal blood alcohol limit is 0.08% for people aged 21 years or older，while people under 21 are not allowed to drive a car with any level of alcohol in their body.A “positive” test result，a result over the legal limit，allows the police to arrest the driver.However，many people who tested positive on the test have claimed that they only drank a “non­alcoholic” energy drink.Can one of these energy drinks really cause someone to test positive on an ABT？Researchers in Missouri set up an experiment to find out.
First，the amount of alcohol in 27 different popular energy drinks was measured.All but one had an alcohol level greater than 0.005%.In nine of the 27 drinks，the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT.They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.
For 11 of the 27 energy drinks，the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken.However，alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed.This shows that when the test is taken plays an important role in the test result.The sooner the test is conducted after the consumption of these drinks，the more likely a positive alcohol reading will be obtained.
小題1:What is the legal alcohol level for a 20­year­old driver in the US?
A．0.000%.　B．0.005%.
C．0.080%.　D．0.096%.
小題2:What is the purpose of the Missouri experiment?
A．To introduce a new method of calculating blood alcohol levels.
B．To discover the relation between energy drinks and ABT test results.
C．To warn people of the dangers of drinking energy drinks.
D．To change the current legal alcohol limit for drivers in the United States.
小題3:The underlined word “subjects” in Paragraph 2 refers to________.
A．the things that are being discussed
B．a(chǎn)reas of knowledge studied in school
C．the participants in an experiment
D．the people who belong to a country
小題4:Which of the following affects the ABT test result most for energy drink consumers?
A．The age of the person who takes the test.
B．The place where the test is given.
C．The equipment that the test uses.
D．The time when the test is taken.
小題5:Which of the following is true according to the passage?
A．A driver whose blood alcohol level is found to be 0.1% will be arrested.

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important, of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.
The total amount of packaging has increased by 12% between 1999 and 2005. It now makes up a third of a typical household's waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for burying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it is also applied to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary materials are collected. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
小題1:What does the underlined phrase "over-consumption" refer to?
A．Using too much packaging.
B．Recycling too many wastes.
C．Having more material than is needed.
D．Making more products than necessary.
小題2:The author uses figures in Paragraph 2 to show_______.
A．the tendency of cutting household waste
B．the increase of packaging recycling
C．the fact of packaging overuse
D．the rapid growth of supermarkets
小題3:According to the text, recycling_________.
A．means burning packaging for energy
B．helps control the greenhouse effect
C．is the solution to gas shortage
D．leads to a waste of land
小題4:What can be inferred from Paragraph 4?
A．Unpackaged products are of bad quality.
B．Supermarkets care more about packaging.
C．Other products are better packaged than food.
D．It is improper to judge quality by packaging.
小題5:What can we learn from the last paragraph?
A．Needless material is mostly recycled.
B．Fighting wastefulness is difficult.
C．People like collecting recyclable wastes.
D．The author is proud of their consumer culture.

The behaviour of a building’s users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions (排放）by 80 percent by 2050, part of which will be achieved by all new homes being zero-carbon by 2016. But this report shows that sustainable building design on its own — though extremely important- is not enough to achieve such reductions: the behaviour of the people using the building has to change too.
The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency (效率)，which instead focus on architectural and technological developments.
‘Technology is going to assist but it is not going to do everything,’explains Katy Janda, a UKERC senior researcher，‘consumption patterns of building users can defeat the most careful design. ’In other words，old habits die hard, even in the best-designed eco-home.
Another part of the problem is information. Households and bill-payers don’t have the knowledge they need to change their energy-use habits. Without specific information，it’s hard to estimate the costs and benefits of making different choices. Feedback (反饋） facilities, like smart meters and energy monitors，could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.
Social science research has added a further dimension (方面），suggesting that individuals’behaviour in the home can be personal and cannot be predicted 一 whether people throw open their windows rather than turn down the thermostat (恒溫器) , for example.
Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.
小題1:As to energy use, the new research from UKERC stresses the importance of________.
A． zero-carbon homesB．the behaviour of building users
C． sustainable building designD．the reduction of carbon emissions
小題2:The underlined word “which” in Paragraph 2 refers to”________.”
A．the waysB．their homes
C． developmentsD．existing efforts
小題3:What are Katy Janda’s words mainly about?
A． The importance of changing building users, habits.
B． The necessity of making a careful building design.
C． The variety of consumption patterns of building users.
D． The role of technology in improving energy efficiency.
小題4:The information gap in energy use _______.
A． can be bridged by feedback facilities
B． affects the study on energy monitors
C． brings about problems for smart meters
D． will be caused by building users’ old habits
小題5:What does the dimension added by social science research suggest?
A． The social science research is to be furthered.
B． The education programme is under discussion.
C． The behaviour of building users is unpredictable.
D． The behaviour preference of building users is similar.

We can make all the jokes we want about taking baths ourselves, but if we are ill in bed and can't get up, we'll be thankful to the nurses who help us get clean. While I am not a nurse, and have never given anyone a bath, I would imagine that it would take a lot of sympathy (同情) and patience to do so.
Yet those who attended the International Conference on Intelligent Robots and Systems last month were introduced to Cody, a robot that can bathe human beings.
The robot has a base that can be turned to all directions, two human­like arms, and movable wrists (腕). It uses a camera to locate parts of the human body.  It then uses bath gloves to clean with a little pressure.
The robot was designed at the Georgia Institute of Technology. Charles Kemp of the Healthcare Robotics Lab is the senior researcher for the project. In a test run, Cody   was able to remove 96% of a test subject's dirt—not bad  for a robot.
But don't go asking for Cody yet—he's still a model.  Yet researchers believe that one day Cody may take the  place of nurses for this task.  Researchers say that Cody  will give patients dignity and protect their personal information. I suppose that would depend on the patient.  I'm  not sure whether a robot using a camera would make me  feel very dignified.
Even so, I can appreciate the need.  We don't have  enough nurses to go around, and those places that are the  most short­handed, for example, nursing homes, are those  that have the most patients who are unable to bathe themselves. Still, before I get there, I hope they think of a better way to solve the problem.
小題1:The writer thinks bathing others must ________.
A．be a lot of fun
B．make you feel thankful
C．take a lot of patience
D．make you feel dignified
小題2:What is the third paragraph mainly about?
A．Why and where Cody was designed.
B．What Cody looks like and who designed it.
C．What Cody can do and where it will work soon.
D．How Cody works and what has made that possible.
小題3:We know from the fourth and fifth paragraphs that ________.
A．Cody can bathe patients better than a real nurse can
B．robots like Cody are being produced in large numbers right now
C．Cody can take the place of nurses completely in hospitals
D．researchers think Cody can protect patients' personal information
小題4:There is a need for Cody because ________.
A．people are becoming lazier
B．it can bring down the cost of nursing
C．there are not enough nurses
D．there are too many nursing homes
小題5:In the writer's opinion, Cody is ________.
A．a(chǎn)cceptable but not perfect
B．strange but not creative
C．clever and strong
D．lovely and careful

Pupils remember more and behave better when 3D images areused in lessons，research suggests.They are quicker to learn andabsorb new concepts，and display higher levels of concentration.
Professor Anne Bamford，of the University of the Arts，London，studied the effectiveness of 3D content in 15 schools across seven countries，including the UK.Pupils in 3D classes can remember more than those in the 2D classes after four weeks，improving test scores by an average of 1 7 percent compared with eight percent for 2D lessons.They gave more detailed answer to the tasks and were more likely to think in 3D, using hand gestures and mime(模仿動作) to answer the test questions successfully.
The teachers commented that the pupils in the 3D groups had deeper understanding，increased attention span, more motivation and higher engagement in the lessons.
Children are used to 3D with the rise of computer games that use the technology­90 percent of those in the study had seen a 3D film.Schools would need 3D­enabled projectors(投影儀)，laptops with good picture capabilities,3D software and glasses for children to introduce animations(動作) into classrooms.
But Danny Nicholson，an educationist，said the technology would be impractical to use inschools and could be costly.He said，“While I think the idea of 3D technology is very interesting，I worry that 3D is a bit of an expensive gimmick(小玩意兒)．There are a few cases where a true3D image might help，but most of the time，good 2D models that can be moved would be just aseffective.”
In the US，one school district in Colorado is already in the process of having 1,000 3Dprojectors fixed in classrooms.And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils.Those who watched the 3D presentations were more engrossed and reported a general increase in their interest in science compared with students who watched the 2D version.
小題1:What is the main idea of the first three paragraphs?
A．There are slight differences between 3D and 2D images.
B．Pupils perform better when 3D images are used in classes.
C．Schools have difficulties in making full use of 3D technology.
D．3D technology is always more effective than 2D technology.
小題2:Danny Nicholson holds the view that 3D ________.
A．is of no help in classes
B．has a bright future in classes
C．is more practical than 2D models
D．may not be affordable for schools
小題3:What can we learn from the last paragraph?
A．3D technology will replace 2D models in the future.
B．Many pupils are now more Interested In science than before.
C．Teachers will use the 3D technology through specific training.
D．3D will soon be put into use in one school district in Colorado.

The following are letters to the editor of a school newspaper  
Dear editor,
I’d like to express my opinion about grades. Students should be allowed to study without worrying about grades. Fortunately, most educators are becoming aware of the fact that students have different interests and abilities. I understand that grades are useful, but grades often limit creativity. Competing for better grades causes many students to turn down opportunities to pursue music, dramatics and sports. Grades force an arbitrary(武斷的) standard of success on everyone. I do not demand as some extremists do, that grades be removed immediately. However, I do believe that less emphasis should be placed on grades. I hope that someday grades will become optional at Village High School.
Magdalena Smith
Drama Club
Dear editor,
I’d like to say something about grades. Let’s face the facts about grades. Grades perform three basic functions. First, grades motivate students to work at their highest level of competence. Second, they act as a reward for hardworking students and as a punishment to students who do not work hard. Finally, grades are used as an effective standard by which to measure student achievement. Good grades help students to get jobs and to get into university. I've spoken with a number of students who have jobs, and most of them say that they were hired primarily on the basis of their grades. My grades helped me land a part-time job and will help me get into university next year. I think grades are extremely important at Village High School.
Simon Harper
Science Club
小題1:Which of the following is not Magdalena Smith’s opinion?
A．Students may give up the chance to learn music and sports for grades.
B．Students’ creativity may not be developed for grades.
C．Grades should not be used to measure a person’s success.
D．Grades should be taken away at once.
小題2:We can learn Simon Harper _____.
A．believes in the benefits of good grades
B．is concerned about students' creativity
C．doesn't work too hard at his studies
D．supports students' interests and abilities
小題3:From the second letter, we can infer that Simon Harper is a/an_____.
