Do you realize that every time you take a step, the bones in your hip are subjected to for

ces between four and five times your body weight？ When you are running, this force is increased further still. What happens if through disease a hip-joint ceases to be able to resist such forces？ For many years hip-joints and other body joints have been replaceable either partially or completely. It is after all a simple ball and socket joint; it has certain loads imposed on it; it needs reliability over a defined life; it must contain materials suitable for the working environment. Any engineer will recognize these as characteristic of a typical engineering problem, which doctors and engineers have worked together to solve, in order to bring a fresh lease of life to people who would otherwise be disabled.

This typifies the way in which engineers work to help people and create a better quality of life. The fact that this country has the most efficient agricultural industry in the world is another good example. Mechanical engineers have worked with farmers and biologists to produce fertilizers, machinery and harvesting systems. This team effort has now produced crops uniformly waist high or less so that they are better suited to mechanical harvesting. Similar advances with other crops have released people from hard and boring jobs for more creative work, whilst machines harvest crops more efficiently with less waste. Providing more food for the rapidly increasing population is yet another role for the mechanical engineer.

According to the passage, when would most weight be imposed on hip-joints？

A．When one is walking.

B．When one is running.

C．When one is standing.

D．When one is lying down.

A 4 year Kid, who does not know what an Email or a Chat App is, prays to God: “Hey, Lo

rd, Please make me a smartphone”. This young kid is asking such a wish from God, because he sees that his parents at home are completely glued to this magical device called smartphone and has no time to look up at him. The smartphone is getting more attention in the house than the child. His parents are present there physically, but their minds are somewhere else. It’s so true that this device has become an inseparable part of our day to day life, and we are addicted to it. We will start feeling restless if we do not look to our phone after a few minutes. We react faster to a phone beep or a message compared to a call by a family member from a different room. We all need to come out of this head-down syndrome. We all need to connect and communicate in real world. We need to put this technology to good use and not become a slave. So what shall we do？ It’s simple: the solution is called “digital break”. This means, when you return home from work, you simply turn off or mute all your digital devices for a few hours every day, or at least once in a while. What do you do then？ You can share your time with the family, chatting with your wife or husband, playing games with your kids, doing things with other family members, etc. in real life. You will soon realize the world outside the smartphone is much more enjoyable

1.The kid is 5 years old.()

2.The kid asked God for a smartphone.()

3.Smartphones have become an inseparable part of our daily life.()

4.We all need to connect and communicate in virtual world.()

Whatever projects you do, you need to have a clear and accurate action plan.Here are a

few ideas to make a good action plan.

First, know your goals.If you don't know where you're going, you're likely to end up anywhere,or even nowhere.The action plan should be specific, measurable, achievable, relevant and timed(SMART).It will take you toward the completion of that goal.

Next, list the necessary strategies that will be used to realize the goals.Be clear about very important events, and also any hidden difficulties you may meet.Break large tasks into smaller ones.Set deadlines for each task.Without clear deadlines, some tasks may never get completed.

Thirdly, follow your plan and don't stop until it's finished.Once your plan is made and shared with the team, the next step is simple: take daily action and make sure that everyone is doing their part.

Finally, change the date if you must, but never give up on the goals.Sometimes unexpected situations and events can appear and prevent you from finishing the tasks on time.If this happens, do not be discouraged –change your plan and continue working to meet your goals.

1.Whether you need to have a clear action plan depends on what kind of project you do.()

2.SMART stands for “suitable, measurable, achievable, relevant, timed”.()

3.When making an action plan, you'd better take possible difficulties into consideration.()

4.Don't change your plan even if some unexpected events happen.()

5.This passage is mainly about how to make a good action plan.()

第5题

Do you find getting up in the morning so difficult that it's painful？ This might be

called laziness, but Dr.Kleitman has a new explanation.He has proved that everyone has a daily energy cycle.

During the hours when you labor through your work you may say that you are “hot”.That's true.The time of day when you feel most energetic is when your cycle of body temperature is at this peak.For some people the peak comes during the morning.For others it comes in the afternoon or evening.No one has discovered why this is so, but it leads to such familiar words as: “Get up, John! You'll be late for work again!” The possible explanation to the trouble is he is at his temperature-and-energy peak in the evening.Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.

You can't change your energy cycle, but you can learn to make your life fit it better.Habit can help, Dr.Kleitman believes.Maybe you're sleepy in the evening but feel you must stay up late anyway.Counteract your cycle to some extent by habitually staying up later than you want to.If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour.This won't change your cycle, but you'll get up steam and work better at your low point.

Get off to a slow start, which saves your energy.Get up with a leisurely yawn and stretch.Sit on the edge of the bed a minute before putting your feet on the floor.Avoid the troublesome search for clean clothes by laying them out the night before.Whenever possible, do routine work in the afternoon and save tasks requiring more energy for your sharper hours.

1.Dr.Kleitman thinks that （）.

A.getting up late in the morning means laziness

B.if your energy peak is in the evening, you might like getting up early

C.people can do nothing about energy cycle

D.spending some time yawning and stretching helps to keep you energetic

2.According to the passage, family quarrels may result from （）.

A.the same energy cycle of family members

B.unawareness of different energy cycles

C.failing to get up early in the morning

D.knowledge of energy cycles

3.If you are used to getting up late in the morning, you are likely to be most energetic （）.

A.in the morning B.at noon C.in the afternoonD.in the evening

4.What's the likely relationship between energy cycle and body temperature？

A.Energy cycle and body temperature are the same things.

B.The higher your temperature is, the less energetic you are.

C.The higher your temperature is, the more energetic you are.

D.There is no direct relation between them.

5.Which of the following statements is not true？

A.One can change his energy cycle once he makes up his mind.

B.We still don't know why people have different energy cycles.

C.Habit will help to make our life fit energy cycles better.

D.If you rise earlier than usual, you will be more efficient at your low point in the morning.

第8题

I recently heard a story about a famous research scientist who had made several very i

mportant medical achievements. A newspaper reporter interviewed him why he was able to be so much more creative than the average person. What set him so far apart from others？

He responded that it all came from an experience with his mother that occurred when he was about two years old. He had been trying to remove a bottle of milk from the refrigerator when he dropped the slippery bottle, spilling its contents all over the kitchen floor—a real sea of milk!

When his mother came into the kitchen，instead of shouting at him, giving him a lecture or punishing him, she said,“Robert, what a great and wonderful mess you have made! I have rarely seen such a huge pool of milk. Well, the damage has already been done. Would you like to get down and play in the milk for a few minutes before we clean it up？”

Indeed, the boy did. After a few minutes, his mother said, “You know, Robert, whenever you make a mess like this, eventually you have to clean it up and restore everything to its proper order. How would you like to do that？ We could use a sponge(海绵), a towel or a mop. Which do you prefer？” He chose the sponge and together they cleaned up the spilled milk.

His mother then said, “You know，what we have here is a failed experiment in how to effectively carry a big milk bottle with two tiny hands. Let’s go out in the back yard and fill the bottle with water and see if you can find a way to carry it without dropping it.”The little boy learned that if he grasped the bottle at the top near the lip with both hands, he could make it. What a wonderful lesson!

This famous scientist then said that it was at that moment that he knew he didn’t need to be afraid to make mistakes.

1.When the mother found the kitchen floor covered with milk, she ________.

A.gave the boy a lecture instead of shouting at him

B.praised the boy instead of punishing him

2.The child’s experience resulted in the following BUT ________.

A.offering the boy a chance to grasp the bottle

A.instructive

C.formal

D.strange

4.The purpose of the passage is to show ________.

A.a usual way to cultivate a child

Kaleil Isaza Tuzman moved to the United States from Columbia when he was 15.Within a f

ew years he was pushing to get ahead, hawking (叫卖) baseball caps to pay the bills his Harvard scholarship didn't cover.

After graduating, he landed on Wall Street, but every night he dreamed of working for himself.During the booming (繁荣的) 1990s, he gave it a try when he and a partner started govWorks - a software company that helped city government go online.

They raised $60 million and expanded like crazy.Then dotcoms started turning into dotbombs - govWorks broke up too.Says Isaza Tuzman, "Entrepreneurs (创业人) have to be ready for both success and failure.In Columbia if you fail, you become a pariah and no one will do business with you.The wonderful thing about this country is you can get up again."

From national parks to moon landings, America has given the world some amazing ideas.But the American Dream is still the biggest - the idea that with hard work and a bit of luck you can be whoever you want to be.Historian James Truslow Adams once wrote that Americans believe "life should be better and richer and fuller for everyone, with opportunity for each according to ability or achievement."

These days there's pressure on the dream idea.A 1978 study of boys born and raised after World War II found an astonishing 23% of the poorest had reached the top of the income heap by 1973.Now, in a typical generation, only 10% work their way from bottom to top.

But every day, some still do make it.After govWorks went bankrupt, Isaza Tuzman built on what he had learned.His new company, Recognition Group, restructures (重组) firms and finds them venture capital？–？nearly $150 million so far.Last year, "Hispanic Business" magazine named him to its 100 Most Influential list.Not bad for a dreamer, in a country built on dreams.

41.What did Kaleil Isaza Tuzman dream of after graduating from college______

A.Working in the Wall Street stock market.

B.Starting a business of his own.

C.Climbing to the top of society.

D.Entering the IT industry.

42.The word "pariah" in " if you fail, you become a pariah" (Line 3,Para.3) most likely means "________."

A.a person who has no future

B.a person to be pitied

C.a person to be condemned

D.a person to be avoided

43.What does the author mean by the American Dream______

A.Everyone can reach the top of the social ladder.

B.People will have a better, richer, and fuller life than their parents.

C.A lucky poor boy can move to the top if he works hard.

D.Everyone enjoys equal opportunity and share in the wealth.

44.Which of the following statements is true of the American Dream these days______

A.It is becoming more and more difficult for one to work their way from the bottom to the top.

B.More and more people are feeling the pressure to work harder in order to realize their dreams.

C.It is becoming more and more unpopular because few people today can move up the social ladder.

D.If one works hard enough, he will eventually make his dreams come true.

45.To Kaleil Isaza Tuzman, the wonderful thing about America is that ________.

A.there is equal opportunity for everyone

B.everyone can get rich if they work hard

C.you can get capital if you want to start a business

D.you can start all over again after failure
