Running on Empty
For almost a century, scientists have assumed, tiredness—or exhaustion—in athletes originates(起源于) in the muscles. Precise explanations have varied, but all have been based on the “Limitations Theory”. In other words, muscles tire because they hit a physical limit: they either run out of fuel or oxygen or they drown in harmful by-products(副产品).
In the past few years, however, Timothy Noakes from the University of Cape Town, South Africa, has examined this standard theory. Tiredness, he argues, is caused not by signals springing from overtaxed muscles, but is an emotional response which begins in the brain. The fundamental nature of his new theory is that the brain paces the muscles to keep them well back from the edge of exhaustion. When the brain decides it’s time to quit, it creates unbearable muscle tiredness. This “Central Governor” theory remains controversial, but it does explain many puzzling aspects of athletic performance.
A recent discovery that Noakes calls the “lactic acid paradox” made him start researching this area seriously. Lactic acid is a by-product of exercise, and the increase of it is often mentioned as a cause of tiredness. But when research subjects exercise in certain conditions created artificially, they become tired even though lactic acid levels remain low. Nor has the oxygen content of their blood fallen too low for them to keep going. Obviously, something else was making them tire before they hit either of these physiological limits.
Noakes conducted an experiment with seven cyclists. It has long been known that during exercise, the body never uses 100% of the available muscle fibres(纤维). The amount used varies, but in some tasks such as this cycling test the body calls on about 30%. His team found that as tiredness set in, the electrical activity in cyclist’s legs declined—even when they were making a great effort to cycle as fast as they could.
To Noakes, this was strong evidence that the old theory was wrong. “The cyclists may have felt completely exhausted,” he says, “but their bodies actually had considerable reserves that they could theoretically tap by using a greater amount of the resting fibres.” This, he believes, is the proof that the brain is regulating the pace of the workout to hold the cyclists well back from the point of extreme tiredness.
1.Which of the following is supported by “the Limitations Theory”?
A.Tiredness is caused by signals from brain.
B.Athletes feel tired when they use up all their energy.
C.The body uses 100% of the muscle fibres in exercise.

A.lactic acid is produced in muscles during exercise
B.the oxygen content in blood may rise after sports

D.the energy in human bodies can be balanced

A.The description of a new test.
B.The explanation of the theory.

College students constantly hear the praises of education. We have all become used to believing that a college education is always a guarantee of an easier life. I was nine years old when my fourth-grade teacher presented me with a task, to write down all of the things I wanted in my life. I filled my paper with things like: own a big house and have servants; be rich and have a good job. The next day my teacher handed back my paper and in red ink she wrote: “GO TO COLLEGE.” For a long time, I was convinced that once I obtained an education, BAM! Life would be easier.
However, education cannot promise all wishes, dreams, and desires. Society must reject the foolish idea that a college education’s main purpose is to satisfy our desires and secure success. Like most challenging things, education is a gamble (赌博) in which results depend entirely on people’s ability to look past their wants to see the realism and reason behind their wants.
For instance, my first year of college, I took a sociology class. In class, we were taught that Third World countries were poor. We learned that our quality of life would be almost impossible for an average person in those countries. I began to examine my own desire to be rich. To always go after money felt selfish when knowing others had none at all. Learning about other society’s financial situations forced me to look beyond what I wanted.
Through the process of education, everything once desired is tested. Wanting something no longer is enough; it’s more important to examine why we want it and whether we really want it. When my desire for money changed, everything changed. I stopped longing for money-driven careers and stopped valuing the people who had them. I began to examine the things I purchased and my reason for wanting them.
Education is a tool to be used to develop and advance our desires, so we can discover the things that are truly significant in life. Education is a source to expand our society to see beyond the superficial (表面的) appeals and the “quick fixes”, leaving the belief of an effortless life behind in order to desire a meaningful one.

A.the author was an ambitious student
B.the author should set more realistic goals

D.a college degree was the key to the author’s dreams

A.To share her learning experiences with readers.

D.To stress the importance of taking a sociology course.
3.With a college education, the author ______.
A.envied rich people
B.lost interest in career
C.desired more material things
D.stopped always seeking more wealth
4.What’s the main idea of the passage?
A.College education promises an effortless life.
B.College education tests and guides our life desires.
C.College education offers solutions to social problems.
D.College education turns young people into gamblers.
Robotic Puppy
Roll over, sit and fetch aren’t commands normally given to a robot, but the smart toy company WowWee has developed a new way of owning a puppy.
CHIP (Canine Home Intelligent Pet) is a robotic dog with blue LED eyes and pointy ears and can sit, shake, dance and make all types of dog noises. It also has tracking capabilities to help locate its owner. “The beauty about CHIP is that it has its own thing going on,” said Sufer, CTO at WowWee. “It has its own life and own kind of intelligence. Even if you’re not around, it’s always doing something.”
CHIP uses wheels to get around and is loaded with sensors (传感器) that give it a 360-degree view to find its ball. The pup is Bluetooth enabled, which connects to a wristband worn by its owner. The wristband, similar to a watch, displays icons (图标) for different commands such as a thumb-up, which allows you to give your pup a digital belly rub. With its owner wearing a smart wristband, it can even follow him around the room.
“We worked on CHIP for about five to six months,” Davin Sufer, told dailymail. com, “We typically come up with a concept, model and product and get it on shelves within a year.” The company plans to start shipping units by next fall, which will allow them to load up the robotic dog with sensors and add many more animated responses per-owner interactivity.
The high-tech toy company made its debut (处女作) in 2004 by releasing the 1.5 foot RoboSapien, which sold millions of units. MiP, which hit shelves last year, is a seven-inch-tall robot covered in white with black accents. Users can direct it, change its emotions and make it dance to any song on your iPad. It’s loud, fast and active.
About 15 years ago, a company called ToyQuest developed the first ever electronic robotic dog — Tekno, the Robotic Puppy. The company sold over seven million units in the first season and 40 million more during its original four years of production. Tekno was built with over 160 emotions and instructions, but most importantly offered consumers a quick look into the future.
1.According to Sufer, the amazing characteristic of CHIP is that _____.
A.it is loaded with special sensors
B.it can make all kinds of dog noises
C.it has quick response to the commands
D.it can do something without instructions
2.CHIP can follow its owner with the help of _____.
A.a watch
B.a smart wristband
C.pointy ears
D.blue LED eyes
3.From the passage, we can know_______.
A.CHIP can be bought in the store now
B.WowWee introduced its first product last year
C.Tekno provided the bright future of the robotic puppy
D.MiP is the first company to develop the robotic puppy
