Question

【題目】What do you usually do when a flying insect lands on your arm? You may blow it away．But what if that insect is a ladybug（瓢蟲）? It is possible that you would let it stay．What is it about ladybugs that we like?

Farmers once thought ladybugs were a good lucky sign．A ladybug in the field meant the crops would be successful and that the weather would be good．The farmers may have thought too highly of such a small bug，but in fact ladybugs do help out with the crops．They eat harmful insects．

Actually，it is not the adult ladybug that eats other insects． It's the baby ladybug．When the baby ladybugs hatch（孵化），they are very hungry and will eat mites，aphids，mealy bugs，green flies，and other crop-destroyers． In the 1800s，ladybugs were brought all the way from Australia to California and set free among orange trees that were dying from being eaten by insects．They completely saved all the trees．

Ladybugs go about their daily business without worrying much about anything．Very few birds or insects will eat a ladybug because it gives off a dangerous fluid（液體）．Ladybugs also protect themselves by playing dead．They fall off leaves and never move until their attacker goes away．

So the next time you see a ladybug，think about what it may be doing．Maybe it is off to save an orange tree．Maybe its next move will be to roll off a leaf and play dead or stand up to a bird about 100 times its size．Maybe it's letting you know that the weather will be good tomorrow．Who knows? Ladybugs are special that way．

【解析】

試題分析：短文大意：農(nóng)民們曾經(jīng)認(rèn)為瓢蟲是好幸運(yùn)的標(biāo)志。在田間瓢蟲意味著莊稼就會成功的，天氣會好的。但事實(shí)上瓢蟲通過吃害蟲幫助他們保護(hù)作物。

【1】D 細(xì)節(jié)理解題。根據(jù)第三段中In the 1800s，ladybugs were brought all the way from Australia to California and set free among orange trees that were dying from being eaten by insects．可知在19世紀(jì)，把瓢蟲從澳大利亞帶到加利福尼亞釋放在橙樹中間通過吃害蟲保護(hù)橙樹。所以該選D。

【2】C細(xì)節(jié)理解題。根據(jù)第四段中Ladybugs go about their daily business without worrying much about anything．Very few birds or insects will eat a ladybug because it gives off a dangerous fluid（液體）可知很少有鳥類或昆蟲會吃瓢蟲因?yàn)樗�散發(fā)出一種危險(xiǎn)的流體。所以該選C。

【3】D詞義猜測題。根據(jù)前半句話Maybe its next move will be to roll off a leaf and play dead可推知"stand up to"得意思為“打架”，所以該選D。
