It happens every day, everywhere I go. At the supermarket and the post office, people keep telling me to enjoy my kids while they are 31 . I spend my days taking care of them and answering 32 questions about everything from why we have two eyes but one nose to 33 there are toilets in the heaven. They 34 me from eating a full meal or getting a full 35 sleep.
Yet, the other day, when I took my kids to a children’s museum, I began to 36 what people were trying to tell me. It was the 37 time we went there without diaper (尿布) bag, baby bottle or stroller (婴儿车). As I watched my sons paint there, I was suddenly 38 by a wave of 39 . My babies weren’t babies any more.
Now I’m paying more attention to the 40 that won’t happen when my kids are 41 .
I’m enjoying when Christ looked up the sky and cried 42 , “Wow! The moon!” In a few 43 , it will take a rare Shrek card or something else to get him that excited. I’m 44 when Nicholas put down his fork at dinner and asked, “Mommy, how are you doing?” About ten years from now , he 45__ not care. When they’re in primary school, they won’t want to hold my 46 any more. In junior high school, they won’t hug me and say, “I love you, too.” In high school, they won’t even want to be 47 with me.
Pretty 48 they’ll both be gone. And I’ll 49 through the supermarket and the post office alone, warning young 50 to enjoy their kids while they are little. Hope they’ll listen.

It’s a sure sign that summer is over and winter is on the way — leaves that were once deep green turn red, yellow and bright orange. It happens every autumn. But did you ever wonder why?
The leaves start changing color when the nights start getting longer and the temperature starts getting cooler. Some scientists think that as the number of daylight hours shrinks, the leaves stop making chlorophyll which makes plants green. The reason is that the process of making chlorophyll requires sunlight. But according to horticulture (园艺) educator Susan Rose from Colorado State University, it turns out leaves don’t really change color at all. “The fall colors are actually there all along,” she said. “But they are covered by the green chlorophyll. As the chlorophyll stops being produced, the other colors can shine through.”
The kind of color that the leaves are going to change to is determined by the plant’s genetic (基因的) background. In some places, the leaves start changing color in September — before autumn even officially begins. In other places, they don’t change until late October or even November. Some scientists say the leaves have been changing color later than usual in recent years. And they think global warming has something to do with that.
In one study, researchers found that the growing season in the Northern Hemisphere was nearly a week longer, on average, in 2008 than it was in 1982. And a professor from Harvard University found that the leaves, west of Boston, Massachusetts, are changing color about three days later than they used to. However, other scientists disagree with the global warming theory. Susan Rose said the leaves in her part of Colorado are changing “right on schedule.” But the leaves in other parts of that state are running a little late. “The lateness in the mountains may have something to do with the really warm late summer and early fall,” she said. “But I’m afraid that’s just a guess.”
