In a research carried out in the UK, it was found that only four out of every five employees were happy at work. Surprisingly, it wasn’t the pay or the love for the work that made people happy. Instead, friendly, supportive colleagues and a good manager have been found to be the primary causes of happiness at work. So how do you develop a sense of joy on the job? Here are some suggestions.

Happiness is a state of mind, so staying happy at work is completely based on a positive attitude towards your job. Focus on the bright side of the work rather than keep talking about what makes you unhappy.

Challenge yourself and take charge of your own growth in your career. Boredom is one of the primary factors that cause people to change jobs. Find new challenges and it’s a great feeling to take control over what you do and see a task through.

Having co­workers you like and enjoy working with is a feature of happiness in the workplace. Talk to people, get to know them and try to get along well with them in the workplace. Meeting new people and getting fresh views can help you to keep yourself interested in your work.

Complete your tasks, no matter how disagreeable or tough they might be. This gives you a sense of achievement and encourages you to work towards your goals in future.

Sitting and staring at your screen all day long isn’t going to help you. Instead, take breaks and go outside for some time. For example, go out for a few minutes to feel the breeze (微风). Eat your lunch outside or work for a few minutes during that hour, which helps you stay happy at work.

1.Which of the following is a main cause of happiness at work?

A. One’s love for the work.

B. Having a good manager.

C. Having many supporters.

D. The pay one gets from work.

2.Why does the author advise us to keep challenging ourselves at work?

A. To do our work more creatively.

B. To learn from new experiences.

C. To avoid feeling bored in the work place.

D. To prove that we have the ability to do the task.

3.The passage is written for___________.

A. general workers

B. new graduates from universities

C. those working on computers

D. people working in big companies

In the near future, people in some parts of the world will watch a new kind of television. It is called the high definition television or the HD-TV. The main difference between an HD-TV and a normal television is the picture. It is more clear and detailed. This is because the HD-TV has many more points and lines that make a television image. Every color television picture contains thousands of red, green and blue points. They all come together as an image in the eye of the person watching. The points are organized in lines that go across the television screen. There are more than five hundred lines in a normal television. The HD-TV has two times as many. To get this clear picture, you must have a big screen. Experts say people using a small screen will see little difference.

The HD-TV also has clear sound. It is like the sound on a CD. All these improvements make an HD-TV very costly.

高一英语单项填空中等难度题查看答案及解析

Scientists may have found a way to reduce shortage of type O blood. Type O is the kind of blood that hospitals most often need. What the researchers are testing is an easier way to make type O blood out of other kinds of blood.

There are four main kinds of blood. Most people born with one of these four: Type A,Type B, Type AB or Type O. Type O can be safely given to anyone. So it is commonly used when a person is injured or sick and has to have blood.

The differences among blood types are linked to whether or not red blood cells contain certain kinds of sugar molecules(分子). These molecules are found on the surface of the cells.They are known as antigens (抗原). These antigens are found with type A, B and AB blood but not with type O.

More than twenty-five years ago, scientists found that the antigens could be removed to create what they called universal-type cells. They could be removed with chemicals called enzymes(酶). But large amounts of enzymes were required to make the change.

Doctor Henrik Clausen of the University of Copenhagen in Denmark led the study. The next step, he says, is to complete safety tests. The team is working with the American company ZymeQuest to test the new method. If it meets safety requirements(*k)and is not too costly,it could become a widely used life-saving tool to increase the supply of universal blood.

1.How do scientists deal with the problem of lacking type O blood?

A.Hope more people to donate type O blood.

B.Make the most of the present type O blood.

C.Develop new ways of using type O blood.

D.Make type O blood out of other kinds of blood.

2.What make people have different kinds of blood?

A.Sugar molecules in red blood cells.

B.People's different living conditions.

C.Peoples various immune systems.

D.The variety of peoples cells and genes.

3.What can we infer from the text?

A.Type O blood can be safely given to anyone

B.Antigens could easily be removed to create universal blood.

C.A Danish company wanted to involve itself in studying blood.

D.The new method is not safe enough to be put into use in hospitals now.

4.What is the best title for the text?

A.Four different kinds of blood

B.A new way to make type O blood

C.The latest research on blood type
