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(日晷)” 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(摆钟)，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（石英钟），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.
1.Humans in the old days used ________ to tell day from night.
A．the rising and setting of the sun
B．batteryoperated quartz clocks
C．atomic clocks
D．digital clocks
2.A sundial works by ________.
A．tracking the movement of the stars around the sun
B．marking a shadow cast by the moving sun
C．burning candles in the sunlight
D．watching the stars
3.Which of the following was NOT used in the past to measure time?
A．An hourglass. B．A sundial.
C．Digital clocks. D．A pendulum.
4.Which of the following ways of measuring time is ordered from the least accurate to the most accurate?
A．Sundial，pendulum，sun.
B．Atomic clock，quartz clock，sundial.
C．Sun，pendulum，atomic clock.
D．Digital clock，hourglass，slowburning candles.

Jane Goodall is best known for her 26-year study of the chimps in the wild. There, she made several revolutionary discoveries that made her one of the greatest field scientists of the 20th century.
Born in London in 1934, the expectations for Jane were standard for the time: a marriage to a nice man, followed by a few children. Fortunately, her mother never discouraged (劝阻, 使气馁) her interests: animals and the natural world. Once her mother discovered that little Jane had brought a handful of worms (幼虫) to bed; rather than screaming, she explained that her new little friends needed the soil to live, and together, they took them back to the garden.
Jane was a bookworm who admired Doctor Dolittle and loved the Tarzan novels. Reading did its usual quiet but life-changing thing: Jane developed a dream to go to Africa and live among the wild animals.
Jane realized her dream on July 14, 1960 when she arrived at Gombe Stream Game Reserve to study the chimps. However, for two months, the chimps escaped when they heard her coming. The only thing she saw was the back of a chimp，running away from her.
“The more I thought of the task I had set myself, the more discouraged I became,” Jane wrote in her first book, In the Shadow of Man.
Eventually, she became familiar with a male chimp and his big family. She observed them kiss, hug, pat each other on the back, shake their fingers at each other. She watched them act very human-like.
One day, moving quietly through the jungle, Jane saw the male chimp sit beside a large termite mound (白蚁土堆). He kept taking small braches from trees and putting them in the holes to fish the ants.
In any case, Jane’s discovery became the talk of the scientific world. Harvard’s Stephen Jay Gould observed, “We must now re-think what the words ‘tool’ (工具) and ‘man’ mean or accept chimps as humans.”
1.What did Jane’s mother do when she found the worms on the bed?
A. She studied them carefully. B. She shouted at her daughter.
C. She threw them into the garden. D. She explained they liked the soil.
2.Which is the major reason that made Jane dream to work in the wild?
A. Doctor Dolittle’s invitation. B. Her interest in chimps.
C. The reading in her childhood. D. Her mother’s encouragement.
3.How did Jane feel during the first two months in Africa?
A. Lonely. B. Frightened.
C. Hopeless. D. Content.
4.What did Stephen Jay Gould’s words imply?
A. Chimps should be accepted as humans.
B. Jane’s discovery is of great importance.
C. Only human beings know how to make use of tools.
D. The scientists should confirm the meaning of the words.

Does a 16-year-old have the ability to change the world, benefiting hundreds of thousands of people?
Olivia Hallisey should believe so. With her invention of new Ebloa test, the girl from US has become the winner of the 2015 Google Science Fair, a yearly competition for creative teenagers who want to make a difference in the world.
Hallisey’s method asks patients to put a sample of their saliva (唾液)onto a testing card. The card changes color if the person is infected with Ebloa. Present Ebloa tests can take up to 12 hours and cost $1,000. Hallisey’s method, by contrast, can be done just in 30 minutes for about $25. Moreover, the test needn’t be put in a refrigerator thanks to the silk material Olivia used to produce the testing cards.
Hallisey started working on the test one year ago when she saw Ebloa spreading across African countries. Her research was based on looking at and using previous research and her own creative ideas.
“She deserves all the praise she’s getting for her hard work, dedication, and intelligence,” said her science teacher Andrew. “Her project is very helpful for the medical diagnosis that we need in parts of the world where Ebola is most common.”
“What affects one country affects everyone,” Hallisey told CNBC. “We have to work together to find answers to the challenges that threaten global health, our environment and our world.”
1.According to the article, Olivia’s tests .
A. use a person’s saliva, which is sorted at a low temperature
B. are less time-consuming and less expensive than current tests
C. are less time-consuming but more expensive than current tests
D. show changes in the color of blood if the person is infected
2.Which of the fo llowing statements is TRUE?
A. Olivia’s discovery could benefit the lives of many people.
B. Olivia’s research was based on her own creative ideas.
C. Olivia set her mind on winning the 2015 Google Science Fair.
D. Olivia’s research began before the outbreak of Ebloa in Africa.
3.What quality makes the test more convenient?
A. The material used can easily be produced in Africa.
B. The material used is easier to store in a refrigerator.
C. The material used needn’t be put in a special device.
D. The material used is common in the places where Ebloa is most comm on.

Some people bring out the best in you in a way that you might never have fully realized on your own. My mom was one of those people.
My father died when I was nine months old, making my mom a single mother at the age of eighteen. While I was growing up, we lived a very hard life. We had little money, but my mom gave me a lot of love. Each night, she sat me on her lap and spoke the words that would change my life, “Kemmons, you are certain to be a great man and you can do anything in life if you work hard enough to get it.”
At fourteen, I was hit by a car and the doctors said I would never walk again. Every day, my mother spoke to me in her gentle, loving voice, telling me that no matter what those doctors said, I could walk again if I wanted to badly enough. She drove that message so deep into my heart that I finally believed her. A year later, I returned to school—walking on my own!
When the Great Depression(大萧条)hit, my mom lost her job. Then I left school to support the both of us. At that moment, I was determined never to be poor again.
Over the years, I experienced various levels of business success. But the real turning point occurred（出现）on a vacation I took with my wife and five kids in 1951. I was dissatisfied with the second-class hotels available for families and was angry that they charged an extra $2 for each child. That was too expensive for the average American family. I told my wife that I was going to open a motel(汽车旅馆)for families that would never charge extra for children. There were plenty of doubters at that time.
Not surprisingly, mom was one of my strongest supporters. She worked behind the desk and even designed the room style. As in any business, we experienced a lot of challenges. But with my mother’s words deeply rooted in my soul, I never doubted we would succeed. Fifteen years later, we had the largest hotel system in the world—Holiday Inn. In 1979 my company had 1759 inns in more than fifty countries with an income of $1 billion a year.
You may not have started out life in the best situations. But if you can find a task in life worth working for and believe in yourself, nothing can stop you.
1.What Kemmons’ mom often told him during his childhood was_______.
A．caring B．moving C．encouraging D．interesting
2.According to the author, who played the most important role in making him walk back to school again?
A．Doctors. B．Nurses.
C．Friends. D．Mom.
3.What caused Kemmons to start a motel by himself?
A．His mom’s support.
B．His previous business success of various levels.
C．His terrible experience in the hotel.
D．His wife’s suggestion.
4.Which of the following best describes Kemmons’ mother?
A．Modest, helpful and hard-working.
B．Careful, helpful and beautiful.
C．Loving, supportive and strong-willed.
D．Strict, sensitive and supportive.
5.Which of the following led to Kemmons’ success according to the passage?
A．Self-confidence, hard work, higher-education and a poor family.
B．Mom’s encouragement, a poor family, higher education and opportunities.
C．Clear goals,mom’s encouragement, a poor family and higher education.
D．Mom’s encouragement, clear goals, self-confidence and hard work.
