    Have you ever wondered why successful people are so successful? Habits play an essential role in shaping our lives. We all know that bad habits can be harmful to your mental and physical well-being. 1. Good habits, on the other hand, can help you rise above others and be at your best. So, what are the common habits of successful persons that set them apart from the rest of us?

2. Most successful figures spend half an hour or more on newspapers, magazines and other books on a daily basis. Most of them have a preference for non-fiction piece that include history, self-help books, and biographies.

Getting up early. The majority of successful people rise approximately 3 hours before their actual workday starts. It gives them adequate time to get additional things done, which may include completing side projects, working out, or just planning ahead. 3.

Working out and staying in shape. We all know the benefits of a healthy lifestyle especially working out and staying physically fit. 4. Clearing your mind and challenging yourself physically with a tough workout daily helps you stay ready for the daily challenges of a business. To sum it up, a strong body carries a strong mind.

Working on communication skills. Communication plays a key role in building constructive interpersonal relationships on a personal as well as on a professional level. 5. However, if you are unable to convey the right information and message in a timely manner, you are less likely to achieve your goals. As with other skills, it is vital to continuously work on improving communication to help you stay more efficient while communicating with anyone on any level.

A. Applying technology.

B. Keeping reading as a habit.

C. After all, the early bird catches the worm.

D. Developing a healthy lifestyle is demanding.

E. Working with data, facts, and figures is important.

F. Successful people require mental and physical fitness.

G. They can block your road to achievement and success.

    “Two centuries ago, Lewis and Clark left St. Louis to explore the new lands acquired in the Louisiana Purchase,” George W. Bush said, announcing his desire for a program to send men and women to Mars. They made that journey in the spirit of discovery. America has ventured forth into space for the same reasons.”

Yet there are vital differences between Lewis and Clark’s expedition and a Mars mission. First, they were headed to a place where hundreds of thousands of people were already living. Second, they were certain to discover places and things of immediate value to the new nation. Third, their venture cost next to nothing by today’s standards. A Mars mission may be the single most expensive non-wartime undertaking in U.S. history.

Appealing as the thought of travel to Mars is, it does not mean the journey makes sense, even considering the human calling to explore. And Mars as a destination for people makes absolutely no sense with current technology.

Present systems for getting from Earth’s surface to low-Earth orbit are so fantastically expensive that merely launching the 1,000 tons or so of spacecraft and equipment a Mars mission would require could be accomplished only by cutting health-care benefits, education spending, or other important programs—or by raising taxes. Absent some remarkable discovery, astronauts, geologists, and biologists once on Mars could do little more than analyze rocks and feel awestruck(敬畏的) staring into the sky of another world. Yet rocks can be analyzed by automated probes without risk to human life, and at a tiny fraction of the cost of sending people.

It is interesting to note that when President Bush unveiled his proposal, he listed these recent major achievements of space exploration pictures of evidence of water on Mars, discovery of more than 100 planets outside our solar system, and study of the soil of Mars. All these accomplishments came from automated probes or automated space telescopes. Bush’s proposal, which calls for reprogramming some of NASA’s present budget into the Mars effort, might actually lead to a reduction in such unmanned science—the one aspect of space exploration that’s working really well.

Rather than spend hundreds of billions of dollars to hurl tons toward Mars using current technology, why not take a decade or two or however much time is required researching new launch systems and advanced propulsion (推进力)? lf new launch systems could put weight into orbit affordably, and advanced propulsion could speed up that long, slow transit to Mars, the dream of stepping onto the red planet might become reality. Mars will still be there when the technology is ready.

1.What do Lewis and Clark’s expedition and a Mars mission have in common?

A.Instant value.

B.Human inhabitance.

C.Venture cost.

D.Exploring spirit.

2.Bush’s proposal is challenged for the following reasons except that     .

A.its expenditure is too huge for the government to afford.

B.American people’s well-being will suffer a lot if it is implemented

C.great achievements have already been made in Mars exploration in America

D.unmanned Mars exploration sounds more practical and economical for the moment

3.Which cannot be concluded from the passage?

A.Going to Mars using current technology is quite unrealistic.

B.A Mars mission will in turn promote the development of unmanned program.

C.Bush’s proposal is based on three recent great achievements of space exploration

D.The achievements in space exploration show how well unmanned science has developed.

4.What is the main idea of the passage?

A.Risky as it is, a Mars mission helps to retain Americas position as a technological leader.

B.A Mars mission is so costly that it may lead to an economic disaster in America.

C.Someday people may go to Mars but not until it makes technological sense.

D.A Mars mission is unnecessary since the scientists once there won’t make great discoveries.

    Working out can help teenagers boost their grades, a new study suggests. Adolescents who routinely engaged in moderate to vigorous（剧烈的）exercise showed long-term improvements in their academic performance, the British Journal of Sports Medicine study reported.

“Our study suggests that the effect of physical activity may be quite large,” John Reilly, a professor at the University of Strathclyde said. The researchers looked at a sample of about 5000 children who were involved in a long-term study that tracks children born in the UK between 1991 and 1992. When children reached 11 years old, their daily physical activity levels were measured using an accelerometer（加速器）for three to seven days. The device, similar to a pedometer（计步器）tracking the number of steps taken, recorded the average time children exercised, which was 29 minutes a day for boys and 18 for girls.

“The actual levels of daily physical activity at age 11 were quite low,” Mr. Reilly noted. The children had their academic performance tested at ages 11 and 13 with compulsory national tests for students, and also at 15 or 16 with the General Certificate of Secondary Education (GCSE) exam. The tests assessed the children’s abilities in English, math and science subjects. The results showed that the more children participated in moderate to vigorous physical activity, the higher their test scores were at age 11 in all three subjects. For girls, science scores were most strongly linked to exercise.

When children were tested again at age 13, their academic scores were still linked to how much they had exercised when they were 11 years old. By the time the youngsters took the GCSE exam, each 17-minute-per‑day increase in physical activity for the boys was linked to an improvement in their scores. Every additional 12-minute increase a day in exercise for the girls was also linked to an increased score, especially in the science category.

The researchers have called for more studies to look at the possible academic benefits that could be derived if students exercised the recommended 60 minutes or more a day.

1.What’s the study about?

A.The influence of exercise on students’ scores.

B.The secrets of students’ ranking high in class.

C.The causes of students’ participating in sports.

D.The ways of improving students’ physical conditions.

2.What is the function of the device used in the study?

A.To record how long students exercise.

B.To record the walking speed of students.

C.To record how many steps students walk.

D.To record the number of calories students consume.

3.What do the study’s results show?

A.Students at age 11 do more exercise than at other ages.

B.Boys at age 13 get more benefits by doing more exercise.

C.Girls’ science scores are more closely related to exercise.

D.More and more students do exercise to improve their scores.

4.What does the underlined word “derived” probably mean in the last paragraph?

A.adopted. B.acquired.

C.concluded. D.displayed.
