“Get your hands off me, I have been stolen,” the laptop, a portable(便攜式的)computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.
The program allows users to display alerts(警報)on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.
Owners must report their laptop missing by visiting to a website, which sends a message to the model: a red and yellow “l(fā)ost or stolen” sign appears on its screen when it is started. Under the latest version(版本) of the software, users can also send a spoken message.
The message can be set to reappear every 30 seconds, no matter how many times the thief closes it. “One customer sent a message saying, ‘You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive (主管) of the company which produces the program, Retriever.
In the latest version, people can add a spoken message. For example, the laptop’s speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, please report me now.”
The Retriever software package(軟件包), which costs $29.95 (£21) but has a free trial period, has the functions of many security software programs. Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access details.
If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet service provider in use, so that the police can be alerted to its location.
Thousands of laptops are stolen every year from homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.
Other security software allows users to erase(刪除)data remotely or lock down the computer.
小題1:The expression “to give the thief a piece of their mind” can be understood as “_______”.
A.to give the thief an alert mind
B.to express the owners’ anger to the thief
C.to remind the thief of his conscience
D.to make the thief give up his mind
小題2:Different from other security software, Retriever can ______.
A.record the stealing process
B.help recognize the lost laptop
C.lock down the computer remotely
D.send a spoken message
小題3:One function of the program is that it allows the owner to ______ at a distance.
A.change some access details for switching on the laptop
B.turn on the laptop by using the original password
C.operate the laptop by means of an alternative password
D.erase the information kept in the stolen laptop
小題4:Which of the following can best summarize the main idea of the passage?
A.With no Retriever, thousands of laptops are stolen every year.
B.A new software provides a means to reduce laptop theft.
C.Retriever has helped to find thieves and lost computers.
D.A new program offers a communication platform with the thief.

Does your child struggle in school? Is he or she afraid of reading out loud, writing an essay, or working out a math problem? While every kid has trouble with homework from time to time, if a certain area of learning keeps going wrong, it might show a learning disorder. Learning disorders, or learning disabilities, are a general term for a wide variety of learning problems.
A learning disability is not a problem with IQ or motivation (動機). Kids with learning disabilities aren’t lazy or slow. In fact, most are just as smart as everyone else. Their brains are just wired (裝電線) differently. Simply put, children and adults with learning disabilities see, hear, and understand things differently. This difference affects how they receive and process (處理) information. This can lead to trouble in learning new information and skills, and putting them to use.
It can be tough to face the possibility that your child has a learning disorder. No parents want to see their children suffer. You may wonder what it could mean for your child’s future, or worry about how your kid will make it through school. But the important thing to remember is that most kids with learning disabilities are just as smart as everyone else. They just need to be taught in ways that suit their unique learning styles.
It’s not always easy to tell whether a child has learning disabilities, for learning disabilities look very different from one child to another. One child may struggle with reading and spelling, while another loves books but can’t understand math. Still another child may have difficulty understanding what others are saying or communicating loud. However, some warning signs are more common than others at different ages. If you’re aware of what they are, you’ll be able to catch a learning disorder early and quickly and take steps to help your child as quickly as possible.
小題1:From the passage, we can infer that_______.
A.students with learning disabilities look quite different from normal students
B.students with learning disabilities can’t do well in their studies
C.only few students with learning disabilities are as clever as normal students
D.it is quite possible for a students with learning disabilities to succeed in their studies
小題2:What is the main idea of the passage?
A.Learning about learning disabilities.
B.How to prevent learning disabilities.
C.Ways to identify learning disabilities.
D.Different learning disabilities.
小題3:What will be most probably discussed following the Paragraph 4?
A.Some ways which help parents teach their children with learning disabilities better.
B.Some suggestions on how to get along with their children with learning disabilities.
C.Some parents may have difficulties in helping their children with learning disabilities.
D.Some warning signs which show that a child may have learning disabilities.

Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills(風車) began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind(碾碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radios. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher cost. Today, there is a global movement to supply more and more of our electricity through the use of wind.
小題1:From the text we know that windmills________.
A.were invented by European armies
B.have a history of more than 2,800 years
C.used to supply power to radio in remote areas
D.have rarely been used since electricity was discovered
小題2:What was a new use for wind power in the late 19th century?
A.Sailing a boat.
B.Producing electricity.
C.Grinding wheat into flour.
D.Pumping water from underground.
小題3:One of the reasons wind was rediscovered in the 1970s is that_______.
A.wind power is cleaner
B.it is one of the oldest power sources.
C.it was cheaper to create energy from wind
D.the supply of coal and gas failed to meet needs
小題4:What would the author probably discuss in the paragraph that follows?
A.The advantages of wind power.
B.The design of wind power plants.
C.The worldwide movement to save energy.
D.The global trend towards producing power from wind.

A victim of climate change
A polar bear's dead body found on the Arctic island of Svalbard, the northernmost part of Norway, has shocked experts who say climate change may be to blame for the death. The starved polar bear in Norway was said to be in good bones by the time a group of explorers came across its body in July.
The bear is thought to have been heading north in a desperate search for sea ice that would allow it to hunt for seals."From his lying position in death, the bear appears to simply have starved to health in April when the Norwegian Polar Institute examined and labeled it. However, the animal was reduced to skin and bones and died where he dropped," polar bear expert Dr. Ian Stirling, a professor at the University of Alberta said, "He had external suggestion of any remaining fat, having been reduced to little more than skin and bone."
Stirling believes the bear starved to death as a result of a lack of sea ice which the animals use as a platform for hunting seals. That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April.
Arctic sea ice reached a record low in 2012, according to a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change.
The International Union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species.
小題1:How did Stirling know the reason for the death of the polar bear?
A.By the food he ate.B.By doing further experiments.
C.By observing other polar bears.D.By his lying position in death.
小題2:The underlined word "vulnerable" probably means _____.
A.easily hurtB.difficult to hunt
C.dangerousD.a(chǎn)mazing
小題3:What is the author's attitude to the incident?
A.Favorable.B.Uncaring.
C.Doubtful.D.Concerned.
小題4:Where does this text probably come from?
A.A novel.B.A guidebook.
C.A news report.D.An advertisement.

Do you know that a fast reader can get the ideas better than a slow reader can? Of course, you save time by reading fast, but this is not the main reason for fast reading. The main reason is that you understand better what you are reading when you read fast.
As your eyes move along the line of print, they make fixations(固定) or pauses. It is important that you see several words at a fixation. It is also important that your eyes leave a group of words quickly and move on to another group. The number of letters or words that you see at a fixation is called your eye span. Pay more attention to improving your rate of reading. With practice you can learn to read faster than you usually read.
The way in which you read always depends on what you are reading and for what purpose. You should know the different ways of reading so that you can apply whatever method that is necessary. Here are four ways of reading:
(1) Skimming is an important kind of reading. This method can be used when you wish to review something that you have forgotten. You can skim to get the main points.
(2) Rapid first reading and then rereading certain parts carefully is important. You may use this type of reading to study a science lesson or a history lesson.
(3) You need to do careful reading and rereading sometimes. This type of reading is necessary for making an intensive(精深的) study of your school subjects, solving maths problems or reading directions.
(4) Rapid reading is used when reading stories for enjoyment. You may also do rapid reading when reviewing material that you already know well.
小題1:The main reason for reading fast is that you can           what you are fast reading.
A.get the ideasB.save timeC.understand betterD.learn well
小題2:The way of reading always depends on           .

Unknown to most Facebook users, the social network actually offers a lot of privacy controls and security features which can help you lock your account, so you can speak freely. If it’s used properly, you’ll never have to worry about whether you will have to “friend” your boss or your mom. You can friend anyone you want while staying comfortable in the knowledge that not everyone gets to see everything you post.
The problem with carrying out these privacy options is that they’re just too confusing for most non-tech clever people to handle. And often, most people don’t want to bother to take the time to learn. To simplify the process, we’re offering one easy step you can take today to help make your Facebook experience safer, more secure, and more private.
Just make “Friend Lists”. Yes, it will take some time, especially if you’re connected to a couple of hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook.
Friend lists, as the name suggests, are lists for classifying your friends into various groups. The nice thing about this feature is that once you set these lists up, you won’t have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list named “Work”, personal friends you’re not very close with into a list called “Acquaintances”, and people you’re related to into a list called “Family”. Those three main categories will separate out the groups of “friends” who you may want to hide some information from.
To create a friend list, click on “Friends” at the top of the Facebook homepage. In the left-hand column, click “Friends” again under the “Lists” section. Now you’ll see a button at the top that says “Create New List”. Click it. In the pop-up that appears, you can name your list and pick members. If you’ve ever shared an application with your friends, the process of doing this will be very familiar.
When you’ve finished making lists, you’ll be able to use them when selecting who can see what (or who can’t!) when configuring (配置) the security settings described below.
小題1:What function isn’t understood by most people on Facebook?
A.Surfing the Internet.
B.Setting safety protection.
C.Sharing personal information.
D.Making foreign friends.
小題2:What can we learn about Facebook according to the text?
A.Its process of privacy-setting is too complex.
B.It displays everything people post.
C.It lacks privacy controls and security features.
D.Its post is designed for technical people.
小題3:What advantage can we get from making friend lists?
A.We can avoid our bosses adding us as friends.
B.We can share applications with friends.
C.We can separate acquaintances from family.
D.We can hide different information from different friends.

In the late 1970’s,many people in North America turned their attention to environmental problems ,and new steel — and — glass skyscrapers were widely criticized. Some ecologists (生態(tài)學家)pointed out that a number of tall buildings in a city often overburden public transportation.
Skyscrapers are also lavish consumers of electric power and water. In just one recent year, the addition of 17 million square feet of skyscraper office space in New York City itself has already raised the top daily demand for electricity by 120, 000 kw — enough to supply the entire city of Albany in New York area for a single day.
Glass—walled skyscrapers can also be especially wasteful. The heat loss ,or gain, through a wall of half 一 inch plate glass is more than ten times that through a typical ordinary wall filled with bricks or board. In order to decrease the pressure on heating and air — conditioning equipment, builders of skyscrapers have begun to use double—layered glass ,and reflective glasses coated with silver or gold mirror films that could reduce glare (強光)as well as heat gain. However, mirror — walled skyscrapers may raise the temperature of the surrounding air and affect neighboring buildings as well.
Skyscrapers put a severe pressure on a city's sanitation (衛(wèi)生)facilities, too. If fully occupied, the towers just within the central area of New York would alone produce 2. 25 million gallons of waste water each year^—as much as the city size of Stanford, Connecticut, which has a population of more than 109,000.
小題1:The underlined phrase“ lavish consumers ”in the 2nd paragraph probably means ____
A.trash producersB.great spendersC.pressure makersD.poor customers
小題2:Glass walls of skyscrapers are specially mentioned in order to _____.
A.show how skyscrapers manage to lessen their pressure
B.explain why skyscrapers can control its air conditions
C.describe further how wasteful skyscrapers could be
D.present the stability of skyscrapers in modern buildings
小題3:From the last paragraph we can learn that _____.
A.central New York skyscrapers are a large waste water producer
B.the central area of New York is as large as the city of Stanford
C.more than 109,000 people live in the skyscrapers in New York
D.New York produces 2. 25 million gallons of waste water each year
小題4:When the writer talks about skyscrapers ,his tone sounds _____

People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (尋求刺激) or imperative (沖動) they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.
Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused tend toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they’re dangerous.”
小題1:The research led by Sanbonmatsu indicates that people who multitask __________.
A.seek high productivity constantly
B.prefer handling different things when getting bored
C.a(chǎn)re more focused when doing many things at a time
D.have the poorest results in doing various things at the same time
小題2:When Sanbonmatsu and his colleagues conducted their research, they __________.
A.a(chǎn)ssessed the multitasking ability of the students
B.evaluated the academic achievements of the students
C.a(chǎn)nalyzed the effects of the participants’ tricky mental tasks
D.measured the changes of the students’ understanding ability
小題3:According to Sanbonmatsu, people multitask because of their __________.
A.limited power in calculation
B.interests in doing things differently
C.inability to concentrate on one task
D.impulsive desire to try new things
小題4:From the last paragraph, we can learn that multitaskers usually __________.
A.drive very skillfully
B.go in for different tasks
C.fail to react quickly to potential dangers
D.refuse to explain the reasons for their behavior

Most students try to learn English grammar using grammar textbooks. They study grammar rules and take grammar tests. They use an analytical approach, attempting to memorize, and then apply, a great number of rules.
However, research has proved this method inefficient and ineffective. The truth is, the human brain simply cannot consciously remember process and use hundreds of or thousands of grammar rules. Real speech is too fast.
Native speakers do not learn grammar in this way, but rather intuitively (憑直覺地) and unconsciously. They learn in a complete way, not by attempting to memorize individual grammar rules. As a result, native speakers use correct grammar fluently and easily.
Fortunately, it is possible for English learners to learn grammar this way. Language teacher Blaine Ray has developed a unique "intuitive" approach to teach English grammar. Her system uses "point of view" stories to teach the patterns of English grammar, allowing students unconsciously to acquire correct grammar without ever studying grammar rules.
In this system, the teacher first tells a simple story from one point of view. It may be told about the past, then repeated, but beginning with "since he was a child"; then repeated again, but this time about the future.
Listening to these stories allows students intuitively and effortlessly to learn English grammar and makes them be able to use it correctly when they speak.
Point of View Stories is a creative new way to study English grammar, and offers hope to millions of frustrated English learners.
小題1:Which of the following ways is approved by the author?
A.Remembering grammar rules
B.Taking grammar tests.
C.Analyzing grammatical structure
D.Applying language to situations.
小題2:What does the underlined part "this way" in the fourth paragraph refer to?
A.Talking to native speakers when learning.
B.Learning English grammar in a complete way.
C.Using correct English grammar.
D.Learning English grammar 4from a teacher.
小題3:From this passage we learn that ______.
A.native speakers learn English grammar by listening to stories
B.Blaine Ray’s method gets students to grasp correct grammar unconsciously
C.Blaine Ray teaches grammar rules by asking students to tell stories
D.it’s hard for students to speak correct English in the new system
小題4: This passage wants to ______.
A.criticize the traditional way of learning grammar
B.introduce a new way to study English grammar
C.a(chǎn)sk students to learn English grammar by listening to stories
D.tell us how the native speakers learn English grammar
小題5:why shouldn’t the English learners use an analytical approach?
A.because the analytical approach can let them learn English grammar effortlessly
B.because the analytical approach makes them be able to use English correctly when they speak.
C.because the analytical approach can’t let them memorize and then apply a great number of rules.
D.because Real speech is too fast.
