Grown-ups know that people and objects are solid. At the movies, we know that if we reach out to touch Tom Cruise, all we will feel is air. But does a baby have this understanding?
To see whether babies know objects are solid. T. Bower designed a method for projecting an optical illusion (视觉影像) of a hanging ball. His plan was to first give babies a real ball, one they could be expected to show surprise in their faces and movements. All the 16 to 24-week-old babies tested were surprised when they reached for the illusion and found that the ball was not there.
Grown-ups also have a sense of object permanence. We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball that rolls under a chair does not disappear and go to never-never land (想像中的地方)?
Experiments done by Bower suggest that babies develop a sense of object permanence when they are about 18 weeks old. In his experiments, Bower used a toy train that went behind a screen. When 16-week-old and 22-week-old babies watched the toy train disappear behind the left side of the screen, they looked to the right, expecting it to re-appear. If the experiment took the train off the table and lifted the screen, all the babies seemed surprised not to see the train. This seems to show that all the babies had a sense of object permanence. But the second part of the experiment showed that this was not really the case. The researcher substituted (替换) a ball for the train when it went behind the screen. The 22-week-old babies seemed surprised and looked back to the left side for the train. But the 16-week-old babies did not seem to notice the switch (更换). Thus, the 16-week-old babies seemed to have a sense of “something permanence,” while the 22-week-old babies had a sense of object permanence related to a particular object.
1.The passage is mainly about ______.
A.babies’ sense of sight |
B.effects of experiments on babies |
C.babies’ understanding of objects |
D.different tests on babies’ feelings |
2.. In Paragraph 3, “object permanence” means that when out of sight, “object ______”.
A.still exists | B.keeps its shape | C.still stays solid | D.is beyond reach |
3.. What did Bower use in his experiments?
A.A chair & a screen | B.A screen & a train | C.A film & a train | D.A box & a chair |
4. Which of the following statements is true?
A.The babies didn’t have a sense of direction. |
B.The older babies preferred toy trains to balls. |
C.The younger babies liked looking for missing objects |
D.The babies couldn’t tell a ball from its optical illusion. |

You only live once, and life is short. It’s easy to look at people who are happy and assume that they don’t understand your pain. The older you get, the more you realize that happiness takes work. People who smile in public have been through as much as people who cry, scream, etc. 1.So how can you live life to the fullest? Here are some tips to help you out:
●Decide what’s important to you. It doesn’t matter what it is. 2. Your parents, friends and society in general all have their opinions, but you’re the only person who will be around for every moment of your life. Do what makes you happy, and everything else will fall into place.
●Ready to take risks. Sometimes, there’s danger involved in life, but every reward carries risk with it. 3.However, if you never take risks, you’ll never get anywhere in life. When people look back on their lives, they regret the chances they didn’t take more than the ones they did.
●Ignore the haters. No matter what you decide to do with your life, there will always be someone around to point out the many ways you will fail. Know that every winner loses, but not every loser wins. 4. Instead, they keep pushing through failure.
● 5.Your being right about something doesn’t mean there aren’t other ways to look at it. Listening to ideas you don’t agree with or understand keeps your brain active and healthy.
A. Keep an open mind.
B. Speak through your actions.
C. Successful people don’t start out successful.
D. Don’t do what you think people want you to do.
E. It is true that some actions might have bad results.
F. They just have the courage and strength to smile through it.
G. Think about your past and future, but only focus on the present.

A mechanical bicycle lock, like a U-lock, should be attached to a solid and immobile object like a rack(架子)to ensure safety. However, these racks are quite rare and popular, thus often occupied and although a bicycle lock prevents the bike from being carried away, as it fixes single parts like the frame or the wheels, other parts can be dismounted. Therefore an electronic system, consisting of several sensors, can extend the range of protection with only few components and less effort.
The ‘RFID Bikealarm’ is a motion sensitive electronic alarm system that is attached to the rails of a bike saddle(座椅). Featuring omnidirectional(全方位)movement sensing to detect tiny movements or speeding-up and a small whistle emitting >120dB alarm sound to scare off potential thieves by arousing attention.
The internal microcontroller uses a complex computer program to distinguish between a serious theft and harmless shaking movement as it senses and adapts to the environment. The usage is quite simple: identify yourself by holding the RFID tag close to the case to lock or unlock the alarm system signaled by feedback sounds. The RFID-technology is predestined for achieving this simple and secure interaction because it doesn’t require any complex system, interaction or other devices—just a small tag.
The ‘RFID Bikcalarm’ is meant to be a useful add-on to mechanical bicycle locks as it massively extends the range of protection with few components. It is low-cost, durable and easy to use. The internal battery can be charged by USB.
1.What does the underlined word “dismounted” in Paragraph 1 most probably mean?
A. fixed up B. found out
C. taken away D. locked up
2.Which of the following shows the right position of the RFID Bikealarm on a bicycle?
A. B.
C. D.
3.What will happen when someone steals a bike with the RFID Bikealarm?
A. Noises will be made. B. The bike will be locked.
C. The thief will be identified. D. Messages will be sent to the owner.
4.Which of the following is a feature of the RFID Bikealarm?
A. It uses complex parts. B. It needs a rack to prevent bike theft.
C. Its high price scares away its buyers. D. It works together with a mechanical lock.

Many people believe that all ice cubes are created equal, but they are not. At least that’s what the folks at California’s Glace Luxury Ice Company would like us to believe. The Davisbased company says that the ice cubes they make are healthier and last longer than the ones that we throw into our drinks on a daily basis. What’s more, the company also says that their ice cubes do mot leave behind an aftertaste(余味)in drinks, like regular ones do.
In order to create these unique ice cubes, Glace Luxury begins with water that has been rid of the hazardous impurities(杂质)that the company says can lead to cancer and exist in regular ice. They then freeze it in large blocks. Once ready, the ice is carved into perfect cubes and each cube measures 2.5 inches across. Besides being healthier, these ice cubes apparently also take longer to melt. The company says that each ice cube can last up to 30 minutes.
Of course, those ice cubes do not come cheap. Those that wish to have a taste of this “tasteless” frozen perfection will have to pay $325USD for a bag of 50 ice cubes. That comes to $6.50USD for a single cube of ice!
The unique product is the brainchild of Robert Sequeira, a former business school lecturer who said that he wanted to establish a profitable business that could be easily scaled. Given that he can make as mush Glace Luxury ice as he needs for as little as $0.12USD per cube, he thinks that the idea certainly meets the standard. Now, if he can find that the few people can afford to buy this Glace Luxury ice, life would be great!
1.People at California’s Glace Luxury Ice Company probably want consumers to believe that _____.
A. ice cubes are healthy for people to use
B. their ice cubes add tastes to drinks
C. all ice cubes are created the same
D. their ice cubes are different
2.What does the underlined word “hazardous” in paragraph 2 mean?
A. Active B. Regular C. Dangerous D .Powerful
3.Compared with regular ice cubes, the ice cubes created by Glace Luxury Ice Company_____.
A. taste much bette
B. look much more beautiful
C. have more different shapes
D. are healthier and melt more slowly
4.What does the author think of the ice cubes created by Glace Luxury Ice Company?
A. They will be a big success
B. They are too costly to make.
C. They are just regular ice cubes.
D. They are too expensive for consumers

Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.
Born in September, 1897, Irene Curies was the first of the Curies’ two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sevigne in Paris.
Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities (设备) to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium. Her services were recognized in the form of a Military Medal by the French government.
In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.
Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity (辐射能). Irene Joliot-Curie died from leukemia on March 17, 1956.
1.Why was Irene Curie awarded a Military Medal?
A.Because she received a degree in mathematics.
B.Because she contributed to saving the wounded.
C.Because she won the Nobel Prize with Frederic
