¡¾´ð°¸¡¿Failure is the mother of success We middle school students have had many tests or exams.
We have both achieved success and suffered from failure. Different students take different attitudes to failure. Some fall in low spirits when they don¡¯t do well in the exams. They usually lose heart and no longer study as before. But most students take an active attitude towards failure. They encourage themselves to be self-confident. They found out and analyze the causes so that they will no longer make similar mistakes. I agree with those with active attitudes.
As we all know, failure is the mother of success. Even great men have failed many times before they succeeded. So we must deal with our failure correctly.

¡¾ÌâÄ¿¡¿Both men and women are living longer these days in industrialized countries. ¡¾1¡¿ In general, they can expect to live six or seven years more than men. One reason for this is biological.

One important biological factor that helps women live longer is the difference in hormones between men and women. ¡¾2¡¿ Between the ages of about 12 and 50, women produce hormones that are involved in fertility(ÉúÓýÄÜÁ¦). These hormones also have a positive effect on the heart and blood flow. In fact, women are less likely to have high blood pressure or to die from heart attacks.

¡¾3¡¿ They help the body defend itself against some kinds of infections. This means thatwomen generally get sick less often and less seriously than men. The common cold is a good example: women, on average, get fewer colds than men.

¡¾4¡¿ Scientists are still not exactly sure how influence aging, but they believe that they do. Some think that a woman¡¯s body cells have a tendency(ÇãÏò) to age more slowly than a man¡¯s. Others think that a man¡¯s body cells have a tendency to age more quickly. ¡¾5¡¿

¡¾ÌâÄ¿¡¿ÔĶÁÏÂÁжÌÎÄ£¬´ÓÿÌâËù¸øµÄËĸöÑ¡ÏA¡¢B¡¢CºÍD£©ÖУ¬Ñ¡³ö×î¼ÑÑ¡Ïî¡£ The National DarkSky Week (NDSW) is a week during which people all over the United States turn off their lights to enjoy the beauty of the night sky without light pollution. This event was started by Jennifer Barlow of Midlothian, Virginia in 2003, and it is becoming more popular each year. It has been supported by the International DarkSky Association, the American Astronomical Society, and the Astronomical League.
This event always occurs in April, during the week of the new moon so that the sky can be as dark as possible for the best viewing conditions.
¡°It is my wish that people could see the night sky without other light in the sky as our ancestors saw it hundreds of years ago,¡± explains Barlow.
Since it only lasts a week and not everyone in the country will take part in it, how will the National DarkSky Week reduce light pollution? The main goal of NDSW is to increase awareness of the harmful effects of light pollution. It is not possible for all of the light pollution in this part of the world to disappear. However, it is possible to make a small difference in the quality of the night sky. Another goal of this event is to promote the use of better lighting systems that direct light toward the ground instead of up into the sky.
Jennifer Barlow states, ¡°The night sky is a gift of such beauty that it should not be polluted by wasted light. In this way, our children will not lose touch with the wonder of our universe.¡±
