Moths are very ugly creatures．At least that is what I always thought until a reliable source told me otherwise．My brother Joseph and I once stayed overnight at our Aunt Linda’s house, our favorite relative．She spoke to us like adults, and she always had the best 21 ．Joseph was only four and still afraid of the dark．Just as I dozed off to sleep, he woke me up and asked, “Jennie, what are those ugly things near the light?” He was pointing to the moths fluttering around the hall light．“They’re just moths, go to sleep,” I told him．

He wasn’t 22 with that answer, so the next time my Aunt walked by the door he asked her to make the ugly moths go away．When she asked why, he said 23 , “Because they’re ugly and scary!” She laughed, rubbing his head, and asked, “Do you know why moths are brown?” Joe just shook his head．

“ 24 , moths were the most beautiful animals in the animal kingdom．They have always been helpful, kind, and 25 creatures．One day the angels up in heaven were crying．They were sad because it was cloudy and they couldn’t 26 the people on earth．Their tears fell down to the earth as 27 raindrops．Now that the sweet little moths 28 to see everyone so sad, they decided to make a rainbow．The moths 29 that if they asked their cousins, the butterflies, to help, they could all give up just a little bit of their colors and 30 , make a beautiful rainbow．

One of the littlest moths flew to ask the queen of the butterflies for help．31 , the butterflies were too vain and selfish to give up any of their colors for neither the people nor the angels．So, the moths decided to make the rainbow themselves．They 32 their wings very hard and the powder on them formed little clouds．They kept giving a little more and more 33 the rainbow stretched all the way across the sky．They had given away all their colors except brown, which didn’t 34 their beautiful rainbow．

Now the once colorful moths were 35 and brown．At the rainbow, the angels up in heaven became joyous．They smiled and the 36 of their smiles shone down on the earth as sunshine．It made the people on earth cheerful and they smiled, too．Now every time it rains the baby moths, who still have their colors, spread them 37 the sky to make more rainbows．”

My brother sank into deep 38 with that story and hasn’t feared moths 39 ．The story my aunt told us had been gathering 40 in the back corners of my brain for years．

　Since the earliest times, trees have always been very useful and important to man who made use of them in many ways for his daily life．Even today trees continue to ___1___ man in so many useful ways．

　They provide man ___2___ fuel for burning and building material in the form of

___3___ ．Without trees it would not be ___4___ to build houses, boats and ___5___ bridges．Furniture such as tables, desks, and chairs___6___ also made of wood．

　In the tropics（热带地区）___7___ it is very warm throughout the year, trees ___8___ man from the hot sun．They are also useful___9___ preventing good and fertile top soil from being washed away ___10___ heavy rains which are so ___11___ in the tropics．

One way of preventing (阻止) floods may be by making rain! This may sound rather 1 . As we know, heavy rain is the 2 of floods, and in Malaysia, most of the 3  are caused by the annual monsoon (一年一度的湿季风), which brings heavy rain to the east coast. If, 4 ,the rain could be made 5  in the South China Sea, there would be 6 floods since the rain could not reach the east coast.

Is it possible to make 7  give up their rain? Yes, it is.

As you probably know, clouds are caused  8  air containing water-vapor (水蒸气). The air rises and, since water-vapor 9  water when it cools, very tiny drops of water are formed. Since these drops are very10 , they float (漂浮) in the air and 11  a cloud. When the cloud rises, however, the drop becomes 12  . Because of this, they 13  together and become big drops. The big drops are no longer able to float because of their 14  , and they fall. As they 15 , they pick up more drops and become bigger. This is the cause of rain.

Rain making 16  making these bigger drops form and fall 17 they would normally do so. This can be done by “seeding” the clouds with chemicals,  18  planting seeds in the ground. Rain can be produced 19  by these chemicals. The seeding is done by 20  which fly through the clouds.
