Science summer camps are one of the best ways to improve creativity of students and teach them a practical approach towards science and its applications (应用).Students taking part in the camps can learn to appreciate science and technology at an early age, to be better positioned for further learning and finally better prepared to face challenges.Apart from theories, scientific experiments and discussions are encouraged at these camps.
The science summer camps are usually held between June and August and it’s good for parents to start planning their children’s summer camps at least 6 to 7 months in advance.This period of time provides an opportunity for them to do proper research and save money.With more than 2,000 summer camps in the US, there is a wide variety for parents to choose from.If the child doesn’t like biology, there is no point sending him to an anatomy (解剖学) science camp.Likewise (同样地), if one thinks that his child limits himself to books throughout the school year, he should try and choose camps which provide students with an opportunity to move out in the open and be physically active.To make the task easier, there are many websites which provide online resource materials to help parents select a summer camp that fits the needs of their children.
Generally, a science summer camp costs between $ 150 and $ 500, depending on where the camp is located, how long it lasts and of course what subject it covers.Some of them also provide scholarships (奖学金) for bright students to encourage them.
56.A science summer camp offers students .
A.chances to be well prepared for future study
B.chances to research and save money
C.ways to get online resource materials
D.chances to live independently
57.What does the underlined word “them” in the second paragraph refer to?
A.Students B.Organizers CScientists D.Parents

A.it’s important for children to relax at the summer camps
B.online resource materials can help to organize a summer camp
C.proper camps should be chosen for children according to their needs

A 1.6-meter tall robot may soon become the best friend for lonely elderly people,as Chinese scientists are making the final sprint(冲刺)toward its market launch(投放),said a senior researcher on the robot project on Saturday.
“We are working on testing the exact functions and ways to reduce the cost in preparations for an expected market launch of the robot in two to three years,”said Li Ruifeng,a member of the project.
He said the team hoped to reduce the cost so that the robot can be priced at 30,000 to 50,000 yuan,which is expected to be an affordable price for most of China’s better-off families.
The robot has been developed with the functions of fetching food,medicine,sounding alarms in case of water or gas leakage,sending texts or video images via wireless communications,and even singing a song or playing chess to entertain its masters.
Li said that the robot,developed independently in China, has technology at the same level as those in western labs.
China set about the research of the robot in 2007,when it was listed as a national key project.It is backed by government funding(拨款).China has the world’s largest elderly population with 159 million people over 60,accounting for 12 percent of its total population. According to a survey by the Ministry of Civil Affairs,more than 10 million caregivers and nurses are needed to attend the elderly population,as most of Chinese elderly prefer to live their retired lives at home.
61.The passage mainly talked about .
A.the problems of Chinese elderly population
B.the advantages of the Robot caregivers
C.robot caregivers for the elderly to lilt market
D.the government’s attention to the elderly
62.The underlined word “backed” in the last paragraph means .
A. supported B.suggested C.controlled D.stopped
63.From the last paragraph we know that .
A.our government pays no attention to the elderly people
B.China has the world’s largest elderly population
C.Chinese elderly people prefer to be looked after by robot caregivers
D.robots are the best friends for the lonely elderly people
64.Which of the following is true according to the passage?
A.Robot caregivers will appear in the market in 2 or 3 years.
B.Robot caregivers can help elderly people do everything.
C.The robot needs some technology from western labs.
D.The robot is expected to be bought by every people.
65.The author wrote the passage to .

You may ask your friends to try to do that when you are having dinner together. There is a saltcellar on the table. You must use salt when you carry out this experiment.
First you put the string across the piece of ice. Then put some salt on the ice. Salt makes ice melt(融化). The ice round the string will begin to melt. But when it melts, it will lose heat. The cold ice cube will make the salt water freeze again. After a minute or two you may raise the piece of string and with it you will raise your piece of ice!
This experiment can be very useful to you. If, for example, there is ice near the door of your house, you must use very much salt to melt all the ice. If you don’t put enough salt, the water will freeze again.
小题1: We must use _______ when we carry out this experiment.
A.fridge | B.some food | C.a table | D.some salt |
A.More than three minutes. | B.Five minutes or so. |
C.Only one minute or two. | D.About ten minutes. |
A.Put the ice cube into the glass of water with the help of the string. |
B.Take out the ice cube in the glass of water with the help of the string. |
C.Take out the ice cube in the glass of water with your fingers. |
D.Put some salt on the ice cube and then put the string across it. |
A.Three. | B.Four. | C.Six. | D.Seven. |
A.physics | B.biology | C.chemistry | D.maths |
“Around 500,000 years ago, at the Peking Man Site at Zhoukoudian in Beijing’s suburban Fangshan district, which is about 50 km from the city of Beijing, there lived early human beings,” says a China history textbook.
The textbook now has to be revised. New dating techniques suggest the remains of Peking Man--- found in the 1920s---are over 200,000 years older than previously thought. What’s important about that date, about 770,000 ago, is that this was an ice age on Earth.
Over Earth’s long history, there have been a number of times when ice and snow covered a large part of its surface. Such periods are known as ice ages.
Earth is in an ice age now. It started about 2 million years ago. Despite the many warm periods since then, scientists regard the whole time as one ice age because of the continuous existence of at least one large ice sheet---the one over Antarctica.
The new discovery was made by Chinese and US scientists. It suggests Peking Man is probably our oldest cold weather human being, said Darryl Granger, an atmospheric scientist at Purdue University whose research appears in Thursday’s edition of the journal Nature.
The average yearly temperature at the time in that part of China was around the freezing mark, but it was too dry for an ice sheet, Granger said.
This raises a question. How did Peking Man survive the cold weather?
Rick Potts, a Smithsonian Institution human origins expert who wasn’t involved in the research, raised three possibilities:
First, fire. Early findings showed signs of a fire in Peking Man’s cave. But there has been debate about whether the fire was accidental or controlled.
Second, fur. There is no evidence that Peking Man used simple tools to make more form-fitting clothes, it’s more likely he wore animal fur.
Lastly, he may have developed gradually to handle the cold. Peking Man may have experienced physiological changes that allowed more blood to flow to his hands and legs, Potts said. “People in general who live in colder climates tend to be shorter and wider,” he explained.
Unlike the times of Peking Man today the global temperature is rising due to the greenhouse effect. In the future, could humans develop to handle the warmth just as Peking Man did to fight the cold?
72. According to the new research, Peking Man actually dates back to _______.
A. around 500,000 years ago B. over 200,000 years
C. about 770,000 years ago D. about 2 million years ago
73. What is the most important standard for scientists to decide an ice age?
A. The weather conditions. B. The continuous existence of any large ice sheets.
C. The average yearly temperature D. The long period of snowfall
74. Which of the following is true of Peking Man?
A. He is the oldest human being B. He used fire to keep warm
C. He wore form-fitting clothes made from fur with simple tools.
D. He might have been shorter and wider than previously thought.
75. The following are all the possibilities EXCEPT _______ that the Peking Man survived the cold weather.
A. putting up tents to keep the cold out B. wearing animal fur
C. using fire in their cave D. developing gradually to handle the cold.
