The brown widow spider is continuing its expansion in Southern California and could possibly move northward into Central California.The brown widow is suspected to have evolved in Africa although it was first described from South America, which adds confusion as to where it might have originated. It is a tropical and subtropical spider having established populations in Hawaii, Florida, parts of Australia, South Africa and Japan. In North America, the brown widow was restricted for many decades to the Florida peninsula. However, around the year 2000, it started showing up in other Gulf Coast states. Brown widows are now known from Texas to Georgia and South Carolina.The brown widow builds its web in protected sites around homes and in woody vegetation with branches. Some typical sites selected by brown widows for web building are empty containers such as buckets and nursery pots, mail boxes, entry way corners, under eaves, storage closets and garages, undercarriages of motor vehicles that are stationary for long periods, and the undersides of outdoor furniture. They choose places that are more exposed than sites chosen by black widows and therefore, appear to be at higher risk for interactions with humans as far as bites are concerned.One recent study demonstrates that the brown widow spider is less poisonous than other widow species. The reason for the weaker effect of brown widow bites on humans is possibly because the brown widow does not have much poison as its larger relatives, but it is really a threat to humans as to its poison. The two major symptoms of a brown widow bite were that the bite hurt when it was given and it left a red mark. These two symptoms are not much different from the bite of normal household spiders.There is no specific information regarding the control of brown widows by farm chemicals. Most current advice is what is used for controlling spiders in general. Therefore, most commercially available farm chemicals should work on brown widows. Avoiding a mess of the house and the garage should reduce nest sites for them. Also, one should store garage items in plastic bags where there might be interactions with spiders. These items include rarely worn garments such as gardening clothes and gloves, recreational items like sports equipment (i.e., baseball gloves) and other items where spiders can crawl up into holes where fingers can be inserted.1. The author wrote this article to _A. announce the result of a research on spidersB. introduce the ways to get rid of the spidersC. report a new finding of the widow speciesD. warn readers against the brown widow2. From the passage we can conclude that _A. brown widows are spreading northwardB. the brown widow originated from AfricaC. brown widows now can be found in all countriesD. there used to be no brown widows in North America3. The third paragraph is mainly about _A. the brown widows web buildingB. the characteristics of the brown widowC. the habitat preferences of the brown widowD. the brown widows threat to human beings4. It can be inferred that _A. brown widows can be killed with any farm chemicalsB. at present people can only control brown widow spidersC. the brown widow has more poison than the black widowD. victims bitten by the brown widow neednt see the doctor答案与解析【文章大意】一种褐色的毒蜘蛛正在美国蔓延，其危害不容忽视。更糟糕的是，目前还没有消灭它的方法，只能尽力进行控制和预防。1. 答案D解析推理判断题。文章从这种蜘蛛的渊源谈起，预测了它的蔓延范围，进而介绍了它的生活习性、危害以及控制方法，所以作者意在警告读者当心这种蜘蛛。2. 答案A解析细节理解题。根据第一段The brown widow spider is continuing its expansion in Southern California and could possibly move northward into Central California可知它们可能会朝北方蔓延。3. 答案C解析主旨大意题。本段指出了这种蜘蛛经常选择的织网的地方，即主要介绍这种蜘蛛的栖息偏好。4. 答案B解析推理判断题。最后一段提到还没有掌握控制这种蜘蛛应当使用的化学药品的具体信息，目前的建议是采用控制蜘蛛的一般方法，并提供了一些预防措施，由此可推断目前人们只能控制它们。1234 PENS is your No. 1 source for promotional pens, advertising pens, and logo pens.

They were just trying to survive. They lived in the desert, and they didnt have enough water to grow their crops.In its simplest form, it was little more than a pipe with holes in it. But behind each hole was a hitech dripper that let out just the right amount of water. Snaked along a row of crops so that the holes were positioned directly above the roots, the pipe could direct each precious drop of water directly to the plants, getting a bigger harvest while using a very small amount of the water.Over time, the farmers improved upon the technology, perfecting the drippers that regulated the flow of water, and connecting the pipelines to computers that could determine exactly how much water each plant needed and when.If the global population kept growing, the rest of the world would increasingly resemble their little community in the desert. So they began selling their irrigation systems in other parts of the world, eventually expanding to more than 110 countries. Netafirm, the company says its lifting people out of poverty and conserving water at a time when the importance of doing so has never been clearer.The mass adoption of drip irrigation wont save the world by itself. To avoid the coming catastrophe, nearly everybody will, in some way, have to do more with less, perhaps through accepting and using other new technologies. Otherwise, its going to get ugly.9. Why is drip irrigation called“the revolutionary technology”？A. It saves the world all by itself.B. It is controlled by computers.C. It makes irrigation more effective
