According to scientists' research, the month in which babies are born could affect them in some ways.

    Babies born in spring get sick easily. Children born under Aquarius may be less clever than those born in other seasons. They may also have shorter lives than those born in autumn  Scientists believe many of the differences can be explained by the mother's exposure to sunlight in pregnancy(懷孕).  Sunlight helps lead to the production of Vitamin D in the body. The lack of this in the first months of life may have a bad effect on mental and physical health.

    Vitamin D, called the "sunshine vitamin", is known to help regulate（調(diào)節(jié)） thousands of genes during development, according to a study of more than two million people. So Vitamin D has a good effect on health  This study showed that people born from April to June had slightly shorter lives than those born in October, November or December. Similar studies in the USA showed that people born in autumn lived about 160 days longer than those born in spring.

    Professor Russell Foster, an Oxford University neuroscientist on seasonal biology, said the conclusions were surprising and interesting. He added, "These are small effects but they are very, very clear. I am not giving voice to star signs and they are just for fun. But it is true that we are affected by our season of birth."

完形填空， 閱讀下面短文，掌握其大意，然后從A、B、C、D四個(gè)選項(xiàng)中選出可以填入空白處的最佳選項(xiàng)。

Do you remember the name of your kindergarten(幼兒園) teacher? I do. Her name was Mrs White.

I don’t remember much about 1 we learned in her class, but my mother once told me that we 2 write a lot. And I would bring back what I wrote and she could see there were so many mistakes. 3 no red corrections. And always a star. Sometimes even a Good! It worried my mother, so one day she went to 4 Mrs White and asked her why she 5 corrected my mistakes.

And my mother says Mrs White said “The children are just 6 to get excited about using words, about forming sentences. I don’t want to lose the interests with red ink(墨水). 7 and grammar can wait. The wonder of 8 won’t... ”.Maybe she didn’t say it exactly like that at that moment. And what my mother gave me was the main idea of what she could remember.

I 9 now and think Mrs White must have been a rather 10 teacher. She encouraged joy, wonder and excitement — even if our expression of it was 11 . Because she believed a bud(花蕾)once nipped(掐斷) never opens.

I used to misspell “beautiful” a lot. Never could quite remember that the e went 12 the a. It annoyed my teacher in high school very much. If I was going to use the word so often, she considered the 13 I could do was spell it right. Finally the e’s and a’s were in their right places. Am glad I didn’t wait on them though. Pretty is 14 to spell but it doesn’t hold as much as you mean sometimes.
And 15 Mrs White I had no worries about writing what I meant. Because Life isn’t Pretty. It’s Baeutiful.
