1、专题限时训练(三十三)史地自然型阅读理解(一)(限时：25分钟) (一)Bees add an estimated eighteen billion dollars a year to the value of American crops. They pollinate(授粉)flowers that become fruits, nuts and vegetables. But, in recent years, honeybee colonies in the United States and Europe have been shrinking. Scientists have pr
2、oposed different theories to explain what is known as colony collapse disorder.New research suggests that a commonly used group of insecticide(杀虫剂) could cause bees to have a hard time finding their way back to their hive. The new research looks at the use of pesticides called neonicotinoids. They w
3、ere first used in the 1990s. They are now put on the seeds of many major crops around the world. The seedlings absorb the chemicals as they grow. That means farmers do not need to spray a whole field. Instead there is a little bit of insecticide inside each plantincluding the pollen(花粉) and the nect
4、ar(花蜜) that the bees want. There is not enough pesticide to kill them. But the new research in the journal Science says it may harm them anyway.Researchers stuck microchips to the backs of the bees. These chips recorded the bees movements as they came and went from their hive. The scientists fed som
5、e bees sugar water with a low dose of a neonicotinoid. The study found that these bees were about twice as likely not to return as other bees.Dave Goulson at the University of Stirling in Britain worked on another study published in Science. He says the pesticides could help explain why bumblebee po
6、pulations are also decreasing.Bayer CropScience makes neonicotinoid pesticides. The companys spokesman Jack Boyne disputed the findings. He also notes that researchers are studying other factors that could affect the bees population. These include parasites, diseases and stress caused by transportin
7、g beehives to farms. Some European countries have banned the pesticides. And there are growing calls to ban them in the United States as well.1The underlined word“shrinking”in Paragraph 1 most probably means “ _”Aincreasing BdecreasingCdisappearing Dcontinuing2Why were microchips tied to the backs o
8、f the bees?ATo record how much honey the bees produce.BTo test how the bees react to the microchips.CTo find if the insecticide affects the bees population.DTo keep track of the bees movements.3It can be inferred from the last paragraph that_.Athe pesticides have been forbidden to use in all Europea

10、oneybee colony collapse disorder.CNew findings about the reduction of bees.DPesticides that kill bees must be banned.(二)The brown widow spider became established in Southern California in early 2000 and has become part of the local spider family in urban Los Angeles and San Diego. The brown widow sp
11、ider is continuing its expansion in Southern California and could possibly move northwards 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 an
12、d 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 widow
13、s 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 cor
14、ners, under eaves(屋檐), 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 wi
15、th 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
16、is really a threat to humans as to its poison. The two major symptoms of a brown widow bite are that the bite hurts when it is given and it leaves 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
17、 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 ite
18、ms 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.5The a

22、ears old this month. A yearlong celebration is planned for Grand Central Terminal, which is usually called Grand Central Station.The huge building has not changed much since it opened in February, 1913. About 750,000 people pass through Grand Central every day, making it the sixth mostvisited place
23、in the world. Some just come to look at it, and others come to visit the stores. But most are there to catch the trains that enter and leave from the station. With 67 underground train tracks, it is the largest train station in the world.The main part of the building has large, arched windows, a jew
24、elled foursided clock and ticket windows. Grand Central has been seen in many movies through the years. Having worked for the transit authority at Grand Central for 30 years and never having lost interest in the building, Dan Brucker is with the New York City Transit Authority, which operates the st
25、ation.“Grand Central is the kind of temple, cathedral that shows the magnificence of rail transportation, and the kind that God would have built if hed had the money.”This is the beginning of 20th century architecture. The ceiling overhead, with its famous mural of the stars, is one of Grand Central
26、 Terminals most famous features. However, eagleeyed visitors will notice that the zodiac(黄道带) on the ceiling is depicted backwards. Some have assumed that this was a mistake by the artist, Paul Helleu. The real reason, according to official documents, is that the painter was inspired by a medieval(中
27、世纪的) painting that showed the heavens as they would have been seen from outside the celestial sphere(天球)Justin Ferate, a historian, has been giving tours of Grand Central Station for 30 years. He says the station was designed to make travel a pleasure.“You know that youre a traveller, that youre goi
28、ng off on a great adventure, and that youre going to follow your stars and find your dream. Youre also going to find your train where its supposed to bewhich is one of the brilliant parts of the design of the building.”Justin Ferate likes to show how the building was designed for large numbers of pe
29、ople.“Why people dont run into each other in Grand Central is simple: each block of stone in Grand Central is the length of your leg. Each block of stone in Grand Central is the length of your arm. Each block of stone is a different colour, so its a checkerboard, based on you.”A tenyearlong fight ag
30、ainst a plan to build a huge office building over Grand Central in 1968 helped create the modern preservation movement. Now, no one would think of changing the beauty of the station.9The main purpose of the passage is to _.Aannounce to people that a celebration is planned for Grand CentralBencourage
