What should you think about in trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to do well at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. Knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.

Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metal work or cookery and look for a job where you can improve these skills.

If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.

Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools. Perhaps you are a poor speller or cannot add up a column of figures. It is bitter to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.

A. affected by 5-HTTLPR, the neurotransmitter serotonin works within the blood

B. there are 5 variants of 5-HTTLPR genes which control people’s moods

C. how the neurotransmitter serotonin works is greatly determined by 5-HTTLPR

D. 5-HTTLPR receives chemical messages from nerve cells

61. What is the main idea of the passage?

A. The Australian government wants its government staff to be happy.

Happiness is genetic

HAPPINESS and sadness are states of being that define the way we view the world. It is often said that some people by nature have a sunny disposition(性格). Now scientists may have discovered why.

Some people may be hard-wired(天生的)for happiness, while others are genetically negative, scientists have suggested in a study published late February, in British journal　 Proceedings of the Royal Society B(《皇家学会学报B》).

Earlier research had already established that the gene known as 5-HTTLPR plays a key role in determining how the neurotransmitter(神经传递素)serotonin(含于血液中的复合胺)works within the brain. Serotonin, a hormone(荷尔蒙), passes chemical messages between nerve cells. It has been closely linked to mood. Several anti-depressant(抗抑郁)drugs regulate serotonin levels.

Scientists had also identified three variants(变体)of the gene. Two so-called "short" variants were linked to a higher risk of depression and suicide(自杀)attempts. Unlike the two "short" variants, the "long" variant of 5-HTTLPR showed a clear dislike of negative images(图像), such as fierce animals, and a clear liking for positive ones, such as flowers.

Researchers from the University of Essex in Britain, led by Elaine Fox, showed participants a series of images.

The images were divided into three kinds: negative ones aimed at inspiring fear or stress such as a spider or person about to commit suicide, pleasant ones and neutral(中性的)ones.

The participants who had the long variant of the 5-HTTLPR gene "showed a clear dislike of negative material alongside a careful attention for positive material," the researchers found. They paid close attention to the pretty pictures, and ignored the frightening ones. On the other hand, the short variant groups had the opposite reaction.

In January, the Australian government organized "happiness workshops", teaching government staff how to be happy. The department that held the "happiness workshops" said unhappy staff weren’t productive staff.

Australian political opposition parties have argued that the "happiness workshops" are probably a waste of money and couldn’t increase productivity as intended. However, whether the workshop will have a happy or disappointing result, we will have to wait and see.
