But there also are some they like. They protect crops against damage from other insects. A good example is the lady beetle, which is also known as the ladybug（瓢虫）.Lady beetles are a natural control for aphids（蜥虫）.Lady beetles are red, orange or black. They often have black spots, though some have light colored spots. Different kinds of lady beetles have different numbers of spots. There are lady beetles with four, five, seven and fourteen spots.Many of the well-known kinds of lady beetles come from Asia or Europe. They now are common throughout the United States.American scientists imported one kind of lady beetle, the multicolored Asian lady beetle, as early as 1916. They released them as an attempt to control some kinds of insects. Over the years, the beetle has become established, possibly helped by some that arrived with imported plants on ships.Experts say over 450 kinds of lady beetles are found in North America. Some are native to the area. Others have been brought from other places. Almost all are helpful to farmers.The Asian lady beetles now in the United States probably came from Japan. The Asian lady beetle eats aphids that damage crops like soybeans, fruits and berries.In the southern United States, Asian lady beetles have reduced the need for farmers to use pest-killing poisons on pecan trees. This popular tree nut suffers from aphids and other pests that the lady beetles eat.But some people say the Asian lady beetle has itself become a pest. They worry that the lady beetles may eat their late-autumn fruit crops.Experts say Asian lady beetles may appear in large numbers in some years. But they say the insects are too helpful to be considered as pests.1. What do ladybugs look like?A. All kinds of ladybugs are of the same color.B. Most of them are red, orange or black.C. They each have the same number of spots on them.D. Most of them have fourteen spots.答案：B由第二段第二句可知B项正确，同时排除A项；由第二段第四句可知C项错 误；D项文中没有提及。2. Asian ladybugs have been in the United States for .A. nine decadesB. hundreds of yearsC. half a centuryD. a century答案：A由第四段第一句可知自1916年至今应为90多年，但离一个世纪还有好几年, 所以A项为最佳选项。3. . According to the passage the following statements are supported EXCEPT.A. there are more than 450 kinds of ladybugs in North America, including native onesB. only some imported ladybugs are helpful to the local plantsC. soybeans, fruits and berries are favorites of aphids.D. pecan trees are common in the south of America答案：B由第五段最后一句可知B项与文章内容相悖。其余选项所述内容都与文章内 容相符。4. According to the experts, ladybugs are.A. more helpful than considered as petsB. more pests than helpful insectsC. helpful as well as destructiveD. are more destructive than helpful答案：A根据末段最后一句可知，专家的观点是瓢虫益大于弊，不应被视为害虫。BI never really paid much attention to one particular flower until this year. The tulip （郁金香）.Yes, it is beautiful. It is one of the first signs of spring. Still, I can，t say that I have attempted to add it to our garden simply because it has such a short lifetime.Tulips are suitable to be gifts. So, the few we have in and around our house have come from the gifts given to us or the ones I have chosen for my wife like this year. Because the weather warmed very early, I wanted to buy something “spring- like“ to begin growing. I chose a small tulip already producing new leaves and gave it to my wife.In a very short time it began growing. Because it was truly the first visible sign of spring for me, I paid more attention to it and I'm glad I did. Every morning it opened in response to the sun welcoming all that it had to offer. Every evening it closed. This went on without hesitation for days. Then one day I found it spread its flowers fully in the sunlight. I had never seen it in that way before. Out of curiosity I touched the flower and two leaves. I felt terrible. It was then that I realized that the flower had come to the end of its days. That was when I realized how much I had been missing by not paying more attention to the tulip.Still, the most amazing part was that it really wasn't over yet. When I would see it as a gone- too- soon dead flower, it was already planning for a comeback. You see, the remaining leaves begin storing energy for future growth next year.文章大意：本文讲述了作者对郁金香一步一步至完全的认识了解。5.
