Zebras have their own bug repellent(驱虫剂)?
Eww bugs! They are so annoying! We humans are lucky that we can apply repellents to avoid nasty bites. But what’s an animal to do? They have no choice but to spend their days shooing them off with their tails, unless, of course, they are zebras, who apparently have their own automatic repellent--- their striped skin!
Scientists had originally thought that the reason why the animal had developed the black and white lines was to help protect itself from predators in the African savannah, because the stripes make it difficult to single out one zebra that is traveling with a herd.While that may be true, the theory has never been tested or proven. Now the experts have another---that the stripes have evolved to repel the annoying horse flies that not only feed off their blood, but also, transmit dangerous germs into the bodies of these innocent animals.
The study was performed by a team of Swedish scientists. One of the clues that got them thinking along these lines was the fact that darker horses got bitten more often than light-colored or white ones.
The fact that zebras are born black and only develop strips as they grow older made the scientists theorize that the stripes may be something the animals have developed to make themselves less attractive to flies.
To test if this may be the case, they painted some boards at a horse-infested horse farm in Budapest with patterns of black and white stripes of varying widths and applied a layer of glue on them. What they noticed was that the places where the black and white stripes were at their narrowest (similar to what zebras have) attracted the fewest flies. They achieved similar results when they painted horses with black and white zebra-like stripes.
While the research are not sure why this may be the case, they believe it may be something to do with the way insects operate---horseflies are attracted to horizontally polarized light(偏振光); since white does not reflect it, white horses are luckier than black ones. But zebras seem to be the luckiest of all. When the researchers measured the polarized light reflected from real zebra skins, they found that it matched light patterns that were the least attractive to horseflies.
While this theory does make logical sense, nobody is 100 percent sure that it is really true, given that it has never been tested on a real zebra. If it is true, it does raise the question of why a horse, a close relative of the zebra has failed to develop stripes. The researchers believe that this could be because there are more horseflies in Africa, where zebras reside, then anywhere else in the world.

解析

试题分析: 人类可以利用各种方法抵御蚊虫的叮咬,那么动物怎么做呢?科学家发现斑马的黑白条纹可能是它们用来抵御蚊虫叮咬的方法。
小题1:词形转化题:根据第二段的句子:Scientists had originally thought that the reason why the animal had developed the black and white lines was to help protect itself from predators in the African savannah, because the stripes make it difficult to single out one zebra that is traveling with a herd.可知科学家原来认为斑马长着黑白的条纹是为了保护自己免受敌人的进攻,protect改成protecting做伴随状语。
小题2:句意理解题:根据第二段的句子:Now the experts have another---that the stripes have evolved to repel the annoying horse flies that not only feed off their blood, but also, transmit dangerous germs into the bodies of these innocent animals. 可知科学家现在又发现斑马长着黑白的条纹是为了保护自己免受叮咬或进攻, bitten / attacked。
小题3:词形转化题:根据第三段的句子:The study was performed by a team of Swedish scientists.可知研究人员是来自瑞典的:Sweden。
小题4:归纳词:根据右边的内容:To test if strips are developed to make zebras less attractive to flies.可知这是这项调查的目的:Purpose。
小题5:句意理解题:根据第三段的句子:One of the clues that got them thinking along these lines was the fact that darker horses got bitten more often than light-colored or white ones.可知白色或浅色的马比黑色的马被咬的可能性要小,所以填likely。
小题6:词形转化题:根据第五段的句子:To test if this may be the case, they painted some boards at a horse-infested horse farm in Budapest with patterns of black and white stripes of varying widths and applied a layer of glue on them. 可知科学家在板上画了不同宽度的黑白条纹。用形容词做定语wide。
小题7:归纳词:右边的内容是这次调查的结果,填Findings。
小题8:指代题:根据第五段的句子:What they noticed was that the places where the black and white stripes were at their narrowest (similar to what zebras have) attracted the fewest flies 可知这里用ones代替stripes。
小题9:考查词组:根据第六段的句子:horseflies are attracted to horizontally polarized light(偏振光); since white does not reflect it,可知attracts改成词组:appeals to。
小题10:句意理解题:根据最后一段的句子:While this theory does make logical sense, nobody is 100 percent sure that it is really true, given that it has never been tested on a real zebra.可知如果不在真的斑马身上做实验,这个结果都不一定是真实的,填Unless。

Some Simple Key* to Transform Your Life
The Power of choice
Every one of us makes countless choices every day. Every choice we make has an impact on our lives.小题1:When hunger strikes, we con reach for a healthy, nutritious snack, or we can choose the* Sugar high of junk food. The more important the decision,

Understanding the basic tips on growing grass will help you create a healthy and green lawn. If you plan the right variety at the right time and in the right place, you’ll achieve success.
Autumn is the ideal growing season for the majority of grass varieties. Prepare the soil in this season as you do for any other plant. Based on the type of grass that you have chosen, the nutrient requirements may differ. For poor soil that is lack of essential plant nutrients, you can supply it with some organic fertilizer.
To grow grass successfully, make sure you select the correct variety that will adapt to the soil conditions of your area and to the growing location. You can choose the American shade grass variety or native grass varieties.
The sowing of grass can be done on bare soil or on an existing lawn. After sowing the grass seeds, cover them with a layer of top soil to quicken the germination (萌芽) process. In the first few weeks, you should irrigate the area every other day. Reduce the watering frequency after the grass has germinated. The addition of proper fertilizers at the right time is necessary for the healthy growth of grass. In the case of grass growing in shady environments, limit the use of fertilizers.
Weed control is another important tip for growing grass. The presence of weeds in grass growing areas leads to competition for water and nutrients, thus resulting in the poor growth of the planted grass. Hence, in order to avoid this condition, ensure that you remove the weeds regularly.
Lastly, one should also watch out for the presence of diseases and pests around the grass growing site in order to preserve the beauty of the lawn.
