Baby girls make their way directly for dolls as soon as they can crawl, while boys will head for the toy cars, a study has shown. The findings, the first to show differences in very young babies, suggest there is a biological（生物学的） basis to their preferences（偏爱）.
Psychologists Dr. Brenda Todd from City University London carried out an experiment involving 90 infants(婴儿) aged nine months to 36 months. The babies were allowed to choose from seven toys. Some were stereotypically boys' toys - a car, a digger, a ball and a blue teddy. The rest were girls’ toys: a pink teddy, a doll and a cooking set. They were placed a meter away from the toys, and could pick whichever toy they liked. Their choice and the amount of time they spent playing with each toy were recorded.
Of the youngest children (nine to 14 months), girls spent significantly longer playing with the doll than boys, and boys spent much more time with the car and ball than the girls did. Among the two-and three-year-olds, girls spent 50 percent of the time playing with the doll while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents’ view on which toys were more appropriate for boys or girls, and the children’s choice.
Dr Brenda Todd said: “Children of this age are already exposed to much socialization(社会化). Boys may be given ‘toys that go’ while girls get toys they can care for, which may help shape their preference. But these findings agree with the former idea that children show natural interests in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to prefer moving objects, probably through hunting instincts（本能）, while girls prefer warmer colours such as pink, the colour of a newborn baby.”
1.Baby boys and girls have different toy preferences probably because__________.
A．baby boys are much more active
B．baby girls like bright colours more
C．there is a natural difference between them
D．their parents treat them differently
2.What can we infer from Paragraph 3?
A．Nine-month-old baby boys don’t play with dolls at all.
B．Two-year-old baby girls sometimes play with cars and balls.
C．Parents should teach their babies to share each other’s toys.
D．The older the babies are, the more obvious their preference is.
3.What conclusion did Dr. Brenda Todd draw from the results of the study?
A．Babies’ preference isn’t affected by social surroundings.
B．Adults purposely（故意地） influence their babies preference.
C．Baby boys preferring to moving toys will be good at hunting.
D．Baby girls preferring warmer colors will be warm-hearted.
4.We may read this article in a_________ section of a newspaper.
A．health B．science C．education D．entertainment

John Blanchard was studying the crowd making their way through the station. He was looking for the girl whose heart he knew, but whose face he didn’t, the girl with the rose.
When reading a book in a Florida library a year before, John became interested not in the contents of the book, but in the notes penciled in the margin. The handwriting reflected a thoughtful soul and beautiful mind. He discovered the former owner’s name in the front of the book: Miss Hollis Maynell.
He located her address and wrote a letter introducing himself. The next day he was shipped overseas to serve in the army. During the next year, they grew to know each other through the mail and their friendship developed. John requested a photograph, but she refused, saying if he really cared, it wouldn’t matter what she looked like. When the day finally came for him to return home, their first meeting was suggested — 7:00 p.m. at the Grand Central Station in New York.
She wrote, “You’ll recognize me by the red rose I wear on my coat.” So now John was in the station to meet the girl with a rose.
As a pretty and slim girl in green came over, John noticed her blue eyes like flowers in spring. He walked directly towards her, entirely forgetting she was not wearing a rose. As John came closer to her, he saw another woman with a red rose stood nearby. Well past 40, this woman had graying hair done under a worn hat. Seeing the girl in green walk quickly away, John felt as if he were split in two. He desired to follow that girl, but longed for the woman whose spirit had truly companioned and supported him.
The woman looked gentle and sensible. John went to her, saying, “I’m Captain John Blanchard. You must be Miss Maynell. I am glad to meet you here. May I take you to dinner?”
She replied with a smile, “I don’t know what this is about. But the lady in green who just went by, begged me to wear this rose on my coat. She said if you asked me out to dinner, I’d tell you she is waiting for you in the big restaurant across the street. She said it was some kind of test!”
1.What do we know about the woman with a rose?
A. She was Miss Maynell’s close friend.
B. She was a waitress in the big restaurant.
C. She was probably a passerby.
D. She was paid to meet John at the Station.
2.Which would be the best title of the text?
A. An Interesting Book B. A Woman With a Rose
C. A Brave Soldier D. A Love Test

Technology is making life easier for some dairy farmers. They use robotic systems to milk their cows. Cows are trained to follow a series of paths that lead to milking stations. Only one cow at a time can enter a station.
Once inside, the cow is rewarded with food. As the cow eats, a robotic arm cleans and connects the animal to the milking machine. A few minutes later, milking is complete. The gate is opened, the cow is released and the next cow enters.
The robotic systems are designed to operate 24 hours a day. The cows get to decide when they want to be milked. Cows are milked an average of about three times a day. Some are milked four to six times a day.
The cows wear collars around their necks that identify them to the system. A computer keeps records on their eating and milking. A cow is released from the station if the computer decides it should not be milked.
The automated system also measures the temperature and color of freshly produced milk. Milk is thrown away if it does not pass the tests.
Professor Plaut believes the systems will appeal especially to the next generation of farmers. She means young people who are more interested in technology and less interested in working all the time on the farm. Still, she says the price of robotic milking systems will continue to limit their use.
Doug and Tina Suhr have more than 100 cows on their family farm. Last year it became the fourth farm in southeast Minnesota to get a robotic milking system. A recent story in a local agricultural newspaper said the first robot cost 175 000 dollars. The second cost 150 000.
Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot. He says the increase in milk production reaches a high of more than six kilograms per cow per day.
1.From the first paragraph, we can infer________.
A．the robotic system is designed to reduce labor
B．cows can be raised by robots in the future
C．robots direct cows into milking stations
D．cows are kept clean by robots on some farms
2.Besides milking cows, the robotic system also can ________.
A．adjust the temperature of milking stations
B．judge the quality of fresh milk
C．improve the appetite of cows
D．keep fresh milk for two weeks
3.Why is the robotic system not popular now?
A．Because young people have no interest in it.
B．Because it is difficult to learn how to use it.
C．Because people can’t afford to buy it.
D．Because it usually causes the waste of milk.
4.According to Doug, what is the wage of an employee?
A．150, 000-170, 000. B．750, 000. C．150, 000 -30, 000. D．30, 000- 32, 000
5.The best title for the passage may be_______.
A．Letting robot milk your cow B．Milking cows by hand
C．Improving the quality of milk D．Drinking fresh milk every day

Technology is making life easier for some dairy farmers. They use robotic systems to milk their cows. These systems are designed to reduce labor and increase milk production.
Cows are trained to follow a series of paths that lead to the milking stations. Only one cow at a time can enter the station. Once inside，the cow is rewarded with food. As the cow eats，a robotic arm cleans and connects the animal to the milking machine. A few minutes later，the milking is completed. The gate is lifted. The cow leaves and the next cow enters. The robotic systems are designed to operate twenty four hours a day. Cows are milked on average about three times a day. Some are milked four to six times a day. The cows wear collars(颈圈) around their necks that identify them to the system. A computer keeps records on their eating and milking. A cow is released from the station if the computer decides it should not be milked. The system also measures the temperature and color of the freshly produced milk. Milk is thrown away if it does not pass the tests. Cows need two to four weeks to learn to use the robotic milking systems. Once trained，the cows no longer require human assistance，unless something goes wrong.
Professor Plaut heads the Department of Animal Science at Michigan State University. She believes the systems will attract especially the next generation of farmers who are more interested in technology and less interested in working all the time on the farm. Still，she says the price of robotic milking systems will continue to limit their use. Doug Suhr has more than one hundred milking cows on his farm. Last year it became the fourth farm in southeast Minnesota to get a robotic milking system. A recent story in a local agricultural newspaper said the first robot cost $175，000 and the second cost $150，000.Doug says the increase in milk production reaches a high of more than 6kg per cow per day.
1.Under robotic milking systems，______ decide(s) whether a cow is suitable to be milked.
A．the robotic arms B．the dairy farmers
C．the cows themselves D．a computer
2.When is human assistance needed during the milking?
A．When the cows enter the milking station every morning.
B．When a robotic arm connects a cow to the milking machine.
C．When the cows are trained to use the robotic milking system in the first two to four weeks.
D．When the temperature and color of the freshly produced milk are measured.
3.Which of the following statements is TRUE according to the last paragraph?
A．Since Doug got the robotic milking system，milk production on his farm has increased.
B．The price of milking machines decreases $25，000 every year.
C．Doug has the largest farm in southeast Minnesota.
D．There are four farms in southeast Minnesota that have robotic milking systems so far.
4.It can be inferred from the passage that ________.
A．the price of robotic milking systems will greatly decrease
B．robotic milking systems are still too expensive to be popular
C．most farmers are too old to use robotic milking systems
D．robotic milking systems don't need to work at night

Dogs wag(摇摆) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found.
Researchers in Italy examined the tail wagging behaviour of 30 dogs, catching their responses to a range of stimuli(刺激物) with video camems. To conduct the study, they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Bari University. The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli. They were tested one at a time.
The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners —a positive
experience— their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appearance of a cat again caused a right-hand side wag, although with less intensity again. The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Researchers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli, they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood (心情) of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that they were required to approach.1.The video cameras were used to catch the dogs’ response because______.
A. The dogs wagged their tails in different directions when they were in different moods
B. they enabled the dogs’ owners to know about their dogs’ habit
C. It was easier to catch the dogs’ response change in tail wagging
D. The dog were put in the wooden boxes and tested one at a time
2.The underlined word “intensity”in the passage means_______.
A. surprise B. worry C. excitment D. interest
3.The underlined word “they” refers to _______.
A. the dogs B. the trainers C. the systems D.the researchers
4.The purpose of doing the experiment is ________.
A. to train dogs for their owners
B. to help dogs find company
C. to help people judge the mood of dogs
D. to help people choose their pet dogs
