Read the following article and select the best answer. Article: Penguins live together,but each pair has a little piece of ground of their own.When a penguin wants to walk through its neighbor's ground,it must ask permission.If it does not do that,it will have to fight.Most of the time,penguins live on the water.They eat shell fish and look after their children carefully. All penguins are good parents--the male penguins are perhaps the best parents in the world. They walk in the sea in the middle of the dark Antarctic water. They choose their wives in the dark.They can only hear them--not see them.Then the female penguins lay their eggs and go away for about two months.The males take care of the eggs.If the eggs get cold,there will be no chicks.There is no food.The snow falls heavily and the wind blows strongly--sometimes at 150 kilometers an hour.The penguins do not move.When the females return from the sea,they will not remember their husbands.It does not matter.Only one thing matters--the eggs.Male penguins never fight--unless a penguin leaves a chick for a minute.They then fight because they all want it.They are strange and wonderful birds. Question: From the passage we know that _ . - penguins live a hard life - penguins live in pairs - penguins will fight if one walks through others' ground without permission - each penguin has a little piece of ground of its own
penguins will fight if one walks through others' ground without permission

(Question)
Read the following article and select the best answer. Article: For thousands of years,we have looked for ways to measure time. Early humans found that the regular movements of the sun,the earth,the moon,and the stars made good ways to measure time. The rising and setting of the sun were used to distinguish day from night. But,eventually,people needed to tell time more accurately,or exactly. So,by using the sun's position in the sky,they divided the day into dawn,morning,midday and evening. Then it was noted that the sun cast a changing shadow as it moved across the sky. Time could be told more accurately by setting up a stick and marking the positions of the sun's shadow. It was the ancient Greeks who divided each position of this "sundial " into hours. But the sun doesn't always shine. So,for the past 6,000 years,many other ways of keeping time have been tried. Slowburning candles were divided into hours,and the hourglass was invented. When all the sand in the top of an hourglass has shifted to the bottom,an hour has passed. Later,the pendulum ,with its regular backandforth movement of weights,was used to move the hands on a clock. Pendulums are still used in grandfather clocks. Today,even more accurate clocks are in use,such as batteryoperated quartz clocks ,digital clocks,and clocks run by electrical tuning forks and tiny atoms. These atomic clocks are the most accurate clocks ever invented. The exact time can be kept to within 1 second a century. Question: Which of the following ways of measuring time is ordered from the least accurate to the most accurate? - Sundial,pendulum,sun. - Atomic clock,quartz clock,sundial. - Sun,pendulum,atomic clock. - Digital clock,hourglass,slowburning candles.
(Answer)
Sun,pendulum,atomic clock.

Ques: Read the following article and select the best answer. Article: I grew up in Lakeland, Louisiana, one of 7 children. We all lived on my parents' farm. At 12, I got a part-time job--milking cows to help support the family. I milked cows at five in the morning and again at two in the afternoon, seven days a week. In the kitchen one Saturday before daytime, I remember complaining to my father and grandfather about having to go milk those cows. My father said, "You know, boy, to work is a blessing ." Going to college was rare for a kid from Lakeland, Louisiana. "Pick something that you like doing to study, and you will always look forward to your work," my father told me. But he also added, "Even having a job you hate is better than not having a job at all." I wanted to be a farmer, but I joined the ROTC program to help pay for college. And what started out as an obligation to the army became a way of life that I was devoted to for 37 years. In the late 1980s, during a visit to Bangladesh, I saw a woman with a baby on her back, breaking bricks with a hammer. I asked a Bangladesh military officer why they weren't using a machine. He told me a machine would make that lady unemployed . Breaking those bricks meant she could earn enough money to feed herself and her baby that day. He told me bad as that woman's job was, it was enough to keep a small family alive, which reminded me of my father's words. I'm retired from the army, but I'm still working to help people be prepared for disaster. I'm not going to stop. I believe in my father's words. I believe in the blessing of work. Question: What kind of program was the ROTC? - It was meant to serve the army. - It was meant for people out of work. - It was meant to serve colleges. - It was meant for poor students.
Ans: It was meant to serve the army.

Read the following article and select the best answer. Article: Bursting into the classroom from recess , 15 children take their seats and face the woman they know as Ms. Yang. "What day is it today?"she asks, in Mandarin Chinese. "Confucius' birthday!"the fifth graders shout in Mandarin. "Why do we celebrate Confucius' birthday?" "Because he's the greatest teacher in the history of China!"exclaims a brown-haired girl. She too is speaking Mandarin. English is rarely heard in Lisa Yang's class at the Chinese American International School(CAIS), despite the fact that few students are native speakers of Mandarin. The United States is actively trying to increase the group of students in"critical languages"such as Mandarin. The students at CAIS are way ahead in such a trend. Mandarin explosion in America Founded 25 years ago, this small private school in San Francisco, USA, does what few other American schools do: It produces fully fluent speakers of Mandarin Chinese, by far the most commonly spoken language in the world. Mandarin Chinese is suddenly hot in American schools. As China becomes the world's leading economy sometimes this century, schools in the U.S. are _ to add Mandarin to their roster of foreign languages or expand Chinese programs already in place. "It really is almost unprecedented . People are looking at China as a force to be reckoned with...And to ensure that the U.S. has the ability to conduct trade, and to work with the Chinese, certainly having an understanding of Chinese language and culture is an advantage,"said Marty Abbott of the American Council on the Teaching of Foreign Languages(ACTFL) . Cultural differences in teaching styles To develop Chinese-language programs has not been smooth. A shortage of trained teachers has made it difficult for some schools to join the race. When schools do get teachers, they often hire them straight from China, and the teachers usually suffer culture shock when they come to the U.S. Robert Liu remembers his first two years in an American classroom. It was not an easy adjustment. "In China, students respect their... Question: What kind of problem is the most difficult to adjust in teaching Chinese in America? - To adapt to the life there. - To communicate with the American students. - To get along well with the American students. - To be fit for the cultural differences in teaching styles.
To be fit for the cultural differences in teaching styles.
