How to write an email?
While many people are accessible by email, sometimes it is difficult to determine how exactly to write an email to them. Here are some tips for you to follow.
Write an appropriate subject line. The subject line should tell the recipient (接收者) immediately what the email is about. Remember that your wording also has to be brief.
It is best to be more formal rather than informal, so when writing to someone you have never met or written to before, a "Dear Jane Smith" is appropriate. When addressing someone whom you are a little familiar with, a "Dr. Smith" is okay until they tell you to address them by their first name, in which case a simple "Jane" will be okay.
Within the first two sentences of your email, your recipient should know exactly why you are writing to him. Sometimes an introduction may have to precede (先于) the sentence that states why you are writing, and sometimes it has to follow.
Use appropriate language. You may be used to using informal language in certain social settings. Even when dealing with colleagues or friends you are familiar with, do not immediately fall back on informal language.
Keep it simple. People may get dozens and even hundreds of emails a day. In that way, they can save much of their time when reading emails.
A. Use proper greetings.
B. Express your ideas clearly.
C. State your purpose at the beginning.
D. Be as specific as possible when writing the subject.
E. However, an email may not be the best place to use such language.
F. It is important to check the language to avoid spelling and grammar mistakes.
G. It is always easier for them if you keep your email as short and brief as possible.

A. Height played a major factor. B. No such association was seen for men. C. The study was observational and couldn't establish cause. D. In fact, the study found that the optimal level of activity for women was 60 minutes a day. E. Neither height nor weight seemed to factor into whether the men reached their 90s, but activity level did. F. In addition, for each 30 minutes a day the men were active, they were 5％more likely to reach that age. G. And they included dog walking, gardening, home improvements, walking or biking to work and sports. |
Living to the ripe old age of 90 may depend on your body size—both height and weight—as well as your level of physical activity, and geeing to influence a woman's lifespan more than it does a man's.
The study found women who lived to 90 were, on average, taller and had put on less weight since the age of 20 as compared to women who were shorter and heavier. {#blank#}1{#/blank#} However, men saw more benefit from physical activity than women.
In 1986 researchers asked over 7, 000 Norwegian men and women between age 55 and 69 about their height, current weight, and weight at age 20. Both genders also told researchers about their current physical activities. {#blank#}2{#/blank#} The men and women were then sorted into daily activity quotas: less than 30 minutes, 30 to 60 minutes, and 90 minutes or more.
Men and women in the study fared very differently when it came to the impact of body size and exercise.
Women who weighed less at age 20 and put on less weight as they aged were more likely to live longer than heavier women. {#blank#}3{#/blank#} The study found women who were taller than 5 feet 9 inches were 31％more likely to live into their 90s than women who were less than 5 feet 3 inches.
{#blank#}4{#/blank#} Men who spent 90 minutes a day or more being active were 39％more likely to live to 90 than men who were physically active for less than 30 minutes.
However, women who were physically active for more than 60 minutes a day were only 21％more likely to live to 90 than those who did 30 minutes or less. And unlike men, there was no bonus for increasing activity. {#blank#}5{#/blank#}
