The octopus’s(章魚)reputation as a human-killer isn’t simply an exaggeration(夸張)—it is a total myth. The octopus can indeed be a deadly hunter, but only of its natural victims. Some shellfish(殼類動物)and an occasional sick or incautious fish have reason to be frightened of this multi-armed hunter, but a person is much too large to interest even the biggest octopus. Even the largest among octopi is much smaller than most people imagine. Far from being large enough to swallow a ship, as monster octopi in movies have been known to do, the largest octopus, found on the Pacific coast, weighs around 110 pounds and grows to no more than ten feet in width.
The hard, parrot-like beak(喙)of an octopus is not used for attacking deep-sea divers, but for cutting open shellfish. Indeed, the octopus possesses such a tiny throat that it cannot swallow large pieces of meat. Instead, it feeds by pouring digestive juices into its victims, and then sucking up the soupy remains. A shellfish that finds itself in the grasp of an octopus has only a short time to live. But human beings are perfectly safe. Still, people rarely care to go close enough to these careful creatures to get a good look at them.
小題1:This passage is mainly about          .
A.the horrors of the octopus
B.the largest octopus in the world
C.octopi and their behavior
D.the octopus’s deadly hunting method
小題2:It is implied but not stated in the passage that          .
A.people have unreasonable fears about the octopus

小題3:What does the underlined part “careful creatures” refer to in the last paragraph?
A.Octopi.B.Shellfish.C.Fish.D.The victims.
小題4:The hard beak of the octopus is used for          .
A.a(chǎn)ttacking deep-sea diversB.cutting up large pieces of meat
C.cutting open its victimsD.defending itself
小題5:From the passage, we can conclude that          .
A.the octopus is not dangerous to man

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.

Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew. And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch(縫合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.
Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle(腳踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical, it could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement(侵犯). Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties(版稅). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
小題1:Barthelemy Thimonnier’s garment factory was burned down because _____________.
A.people did not know how to put out the fire
B.Elias Howe thought Thimonnier had stolen his invention
C.the sewing machines was couldn’t work finally
D.workers who feared the loss of their jobs to a machine set fire
小題2:Which of the following is NOT TRUE according to the passage?
A.Singer is an American inventor and manufacturer.
B.The Singer sewing company became more practical.
C.The foot treadle helped to make the sewer’s hands free.
D.Singer made improvements to the design of sewing machines.
小題3:Why did the court force Isaac Singer to pay Elisa Howe a lifetime of royalties?
A.Because the judge was against Singer for his surly attitude.
B.Because Howe had already patented the lockstitch used by Singer.
C.Because Singer had borrowed money from Howe and never repaid it.
D.Because Singer and Howe had both invented the same machine.
小題4:Which of the following would be the best title for this passage?
A.Stitch in Time Saves Nine
B.The Case between Howe and Singer
C.Patent Laws on the Sewing Machine
D.The Early History of the Sewing Machine

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

Dogs can know the meaning of a human perspective, say researchers.
Dogs are more capable of understanding situations from a human's point of view than has previously been recognized, according to researchers.
They found dogs were four times more likely to steal food they had been forbidden, when lights were turned off so humans in the room could not see.
This suggested the dogs were able to alter their behavior when they knew their owners' perspective had changed.
The study, published in Animal Cognition, conducted tests on eighty-four dogs.
The experiments had been trying to find whether dogs could make their behavior suitable to react to the changed circumstances of their human owners. It wanted to see if dogs had a "flexible understanding" that could show they understood the viewpoint of a human.
It found that when the lights were turned off, dogs in a room with their human owners were much more likely to disobey and steal forbidden food.
The study says it is "unlikely that the dogs simply forgot that the human was in the room" when there was no light. Instead it seems as though the dogs were able to differentiate between when the human was unable or able to see them.
Juliane Kaminski carried out the research into how dogs are influenced by human circumstances.
Dr Juliane Kaminski, from the University of Portsmouth's psychology department, said the study was "incredible because it implies dogs understand the human can't see them, meaning they might understand the human perspective".
Previous studies have suggested that although humans might think that they can recognize different expressions on their dogs' faces, this is often inaccurate and a projection of human emotions.
“Humans constantly attribute(歸屬) certain qualities and emotions to other living things. We know that our own dog is clever or sensitive, but that's us thinking, not them,” said Dr Kaminski.
“These results suggest humans might be right, where dogs are concerned, but we still can't be completely sure if the results mean dogs have a truly flexible understanding of the mind and others' minds. It has always been assumed only humans had this ability.
小題1:According to the passage, which of the following is TRUE?
A.The researchers made the test on dogs in eighty-four countries.
B.Dogs always obey and don’t steal forbidden food.
C.Dogs may adapt their behavior in response to the changed circumstances.
D.The research is carried out to find out how dogs are influenced by light.
小題2:Which of the following can best serve as the title of the passage?
A.Dogs---Our Loyal Companions Understand Us Most.
B.Dogs Are Our Best Friends.
C.Dogs Can Understand Us In a Way, Researchers Say.
D.Dogs Have Certain Qualities and Emotions of Human Beings, Researchers Say.

A.Textbooks.B.Advertisements.C.Instructions.D.Magazines.

Last week, President Barack Obama gave a back- to-school speech to students at the Julia R. Masterman Laboratory and Demonstration School in Philadelphia, Pennsylvania. Students in schools across the country al­so tuned in to watch the President's speech on TV. He stressed the importance of trying new things, working hard and believing in yourself.
While admitting that times are tough for families across the country, Obama reminded students that hard work now can mean big success later. “Nobody gets to write your destiny(命運)but you,” he said. “Your future is in your hands. Your life is what you make of it. And nothing—absolutely nothing—is beyond your reach."
Obama spoke about his own life, and lessons he learned from his mother, who had to remind him to stay focused on his studies. He told students the recipe (訣竅) for success: “Showing up to school on time. Paying attention in class. Doing your homework. Studying for exams. Staying out of trouble. ”
Obama encouraged students to embrace(欣然接受)what makes them different. “We shouldn't be em­barrassed by the things that make us different,” he said. “We should be proud of them.”
He also suggested taking advantage of all of the opportunities at your school, and always being open to trying new things. “Just because you’re not the best at something today doesn't mean you can't be tomorrow,” he said. “Even if you don't think of yourself as a math person or as a science person—you can still excel in those subjects if you're willing to make the effort. And you may find out you have talents you’d never dreamed of.”
