Around the world, honeybee groups are dying in huge numbers: About one-third of nests collapse each year. For bees and the plants they pollinate (授粉) — as well as for beekeepers, farmers, honey lovers and everyone else who appreciates this marvelous social insect — this is a catastrophe.
Honeybee collapse has been particularly worrying because there is no one cause, but rather a thousand little cuts. The main elements include the mixed impact of pesticides (杀虫剂) applied to fields, as well as pesticides applied directly into nets to control bugs, pests and diseases; nutritional shortages caused by vast acreages of single-crop fields that lack diverse flowering plants; and commercial beekeeping itself, which destroys groups by moving most bees around the country multiple times each year to pollinate crops.
The real issue, though, is not the volume of problems, but the interactions among them. Here we find a major lesson from the bees that we ignore at our risk: the concept of synergy (协同作用), where one plus one equals three, or four, or more. A typical honeybee colony contains remains from more than 120 pesticides. Alone, each represents a benign dose (良性剂量). But together they form a poisonous soup of chemicals whose interplay (相互作用) can greatly reduce the effectiveness of bees’ immune systems, making them easier to suffer from diseases.
Observing the death of honeybees should warn us that our own well-being might be similarly threatened, and the widespread collapse of so many groups presents a clear message: We must demand that our regulatory authorities require studies on how exposure to low dosages of combined chemicals may affect human health before approving compounds.
Bees also provide some clues to how we may build a more collaborative relationship with the services that ecosystems can provide. Bees could offer some of the pollination service needed for agriculture. People discovered that crop harvests, and thus profits, are maximized if some cropland are left uncultivated for bees. Meanwhile a variety of wild plants means a healthier, more diverse bee population, which will then move to the planted fields next door in larger and more active numbers.
1.Which of the following is NOT the cause that leads to bees dying?
A. Lack of nutrition from enough diverse flowering plants.
B. The pests and diseases of the bees.
C. The beekeepers’ destroying without intention
D. The pesticides applied to crops.
2.By saying “one plus one equals three, or four, or more” in Paragraph 3, the author means that ____.
A. bees united mean they are much more powerful

This is a dangerous world we live in. The number of murders goes up every year, people are dying of cancer, more people contract HIV, more teens are using drugs, ect. You know this because you’ve heard all the statistics on the news and in the paper. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background statistics mean very little.
This growing trend of reporting only part of the information is becoming dangerous. For example, several years ago a high school student reported the dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors, is often found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statement is true, yet this chemical is necessary to all life on earth. The students made a mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.
The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave our information that is different from his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people die each year when skiing, while 897 die from lightening strikes, but which is really more dangerous? If you think more about it, you will realize far fewer people go skiing each year than the number of people in danger of a lightning strike. When you think about it again, skiing is more dangerous than you might at first think when looking at the statistics. If we teenagers are to be left in this world, we had better be able to think critically, and form our own views, rather than be easily persuaded by another’s. To be warned is just to be prepared.

高三英语阅读理解中等难度题查看答案及解析
Both honeybees and ants are social insects that live in groups called colonies. They survive by means of their collective intelligence. Their decision-making power is distributed throughout the group; that is, no one ant or bee makes decisions for the group. Instead, they work together. As Deborah M. Gordon, a biologist of Stanford University, says, “Ants aren’t smart. Ant colonies are.” The same is true for bee colonies. Although bees and ants are quite different physically, they have a lot in common in terms of their behavior. Specifically, honeybees and ants have similar roles within the colony, both have communication systems, and both have the capacity of learning.
Ants communicate by using chemicals called pheromones, which can alert others to danger or to a food source. For example, when worker ants find a promising source, they let the rest of colony know how to find it by leaving a trail of pheromones on the way back to the colony. The other ants pick up the message using their sense of smell. Bees, on the other hand, use movement to communicate with each other. Worker bees send message to each other by means of a “dance”. Different speeds and movements send different messages. For example, when worker bees called scouts go out to find a new hoe for the colony, they return and do a dance for the other worker bees that indicates the location of the new home and how suitable it is. The faster the scouts dance the better the new location is.
Honeybees and ants are both capable of learning. One Chinese study found that bees can be trained to learn and remember a route to a food source. The researchers also found that bees can be taught to recognize hidden objects and use the concepts of “sameness” and “difference” to accomplish certain tasks. Ants take this one step further. Recent America research has shown that ants not only have the ability to learn, but also can teach their foraging skills to other younger ants. They observed that older ants accompany young ants in search of food and teach them the route and how to avoid obstacles.
As we can see, the social behavior of honeybees and ants is quite similar. Both coordinate complex actions and accomplish crucial survival tasks by cooperating in groups consisting of many individuals. Unintelligent as they may be as individuals, as groups they often show amazing brilliance as they go about their everyday activities.
1.What do ants and bees have in common?
A. They make use of collective intelligence.
B. They live in similar-sized colonies.
C. They have small leadership groups that make all decisions.
D. They use the same method to communicate with each other.
2.What docs the speed of a bee’s dance indicate?
A. The distance to a neighboring colony.
B. The quality of a new colony location.
C. The discovery of a new food source.
D. The direction to a potential food source.
3.In paragraph 3, how docs the author demonstrate the idea that Honeybees and ants are both capable of learning?
A. By using statistics. B. By explaining reason.
C. By presenting study findings. D. By stating opinions.
4.What does the underlined part “foraging skills” refer to in the third Paragraph?
A. The skills of communicating. B. The skills of sacking food.
C. The skills of leaning. D. The skills of finding a new home.

At the end of the 19th century, one in seven people around the world had died of tuberculosis or TB for short (肺结核)，and the disease ranked as the third leading cause of death in the United States. While physicians had begun to accept that TB was caused by bacteria, this understanding was slow to catch on among the general public, and most people gave little attention to the behaviors that contributed to disease transmission. They didn’t understand that things they did could make them sick. It was common for family members, or even strangers, to share a drinking cup.
In the 1890s the New York City Health Department launched a massive campaign to educate the public and reduce transmission. The “War on Tuberculosis” public health campaign discouraged cup-sharing and urged states to ban spitting inside public buildings and on sidewalks and in other outdoor spaces. Changes in public behavior helped successfully reduce the spread of TB.
Disease can permanently change society, and often for the best by creating better practices and habits. Crisis sets off action and response. Many infrastructure improvements and healthy behaviors we consider normal today are the result of past health campaigns that responded to serious outbreaks.
In the 19th century, city streets in the U.S. overflowed with dirt. People threw their unwanted newspapers, food scraps, and other trash out of their windows onto the streets below. The plentiful horses pulling streetcars and delivery carts dropped urine and waste every day. Human waste was a problem, too. Those in tenement (租户)housing did not have their own facilities, but had 25 to 30 people sharing a single outhouse. These toilets frequently overflowed until workers known as “night soil men” arrived to deal with waste, only to dump it into the nearby harbor.
As city and health leaders began to understand that the frequent outbreaks of TB that swept across their cities were connected to the garbage, cities began setting up organized systems for handling human waste. Indoor toilets were slow to catch on, due to the cost and need of a plumbing system. Improvements in technology helped the process along. Following Thomas Clapper’s improved model in 1891, water closets became popular, first among the wealthy, and then among the middle-class. Plumbing systems, paired with tenement house reform, helped remove waste from the public streets.
Disease greatly improved aspects of American culture, too. As physicians came to believe that good ventilation(通风))and fresh air could help fight illness, builders started adding porches and windows to houses. Real estate investors used the trend to market migration to the West, encouraging Eastern physicians to convince TB patients and their families to move thousands of miles from crowded, dirty Eastern cities to the dry air and sunshine in places like Los Angeles and Colorado Springs.
Some of this influence continues today. While we know that sunshine doesn’t kill bacteria, good ventilation and time spent outside does benefit children and adults by promoting physical activity and improving spirits. This fresh-air “cure” also eventually transformed the study of climate into a formal science, as people began to chart temperature, barometric pressure and other weather patterns in hopes of identifying the “ideal” conditions for treating disease.
Public health emergencies have inspired innovations in education. Starting in 1910, Thomas Edison’s lab, which had invented one of the first motion picture devices in the 1890s, cooperated with anti-tuberculosis activists to produce short films on TB prevention and transmission-some of the first educational movies. Screened in public places in rural areas, the TB movies were also the first films that viewers had ever seen.
As we are seeing with the coronavirus today, disease can impact a community--changing routines and shaking nerves as it spreads from person to person. But the effects of epidemics extend beyond the moments in which they occur.

4.Why was it slow for water closets to become popular?
A.They were too expensive for the poor to obtain.
B.There were many drawbacks of the early models.

D.People in tenement houses resisted such a device.
5.What was the change in American population migration then?
A.The vast majority of urban citizens moved to the West.
B.More people lived in the West than those in the East.
C.Many fled to rural areas with good ventilation and fresh air.
D.Patients and their family were encouraged to move westwards.

B.People adopt the habit of regular temperature-taking.
C.Films have become the primary way to educate people.
D.Ideal conditions for treating disease have been defined.

5G has the potential to disrupt a huge number of industries, including one of the world’s oldest: Farming. Next-generation 5G networks can be 100 times faster than 4G, making communication between devices and servers much quicker. 5G can also carry much more data than other networks. That makes the technology ideal for transmitting information from remote sensors and drones, key tools that are being tested by farmers. 5G is also helping to automate farming processes.
UK initiative 5G RuralFirst launched a smartphone app in March called Me+Moo, which lets farmers track a “connected” cow and receive daily updates on the animal’s health and behavior. The system, which is being tested on cows at the Agri-Epi Center in Somerset, England, is funded in part by UK government and supported by the tech company Cisco (CSCO). The cows wear 5G-connected collars that send data to the app on everything from what they’re eating to how they’re sleeping. Farmers can see the information instantly. “This provides peace of mind that the cows are happy, healthy and behaving normally, as well as early warning if they are getting sick, are pregnant or need to be checked,” said project manager Duncan Forbes.
Yet to make a difference, 5G will first need to be installed in rural areas. The UN Food and Agriculture Organization (FAO) predicts that in order to provide for the world’s rapidly rising population, the planet will need to grow 70% more food in 2050 than it did in 2009. “To respond to those demands, farmers will need new technologies to produce more from less land, with fewer hands,” reads one report from the organization.
In 2017, another 5G RuralFirst project became the first in the world to successfully plant, tend and harvest a crop without a single human stepping foot in the field. Autonomous Automatic tractors sowed the seeds, drones with sensors monitored the crops, and smaller machines took samples from fields to assess what fertilizers and pesticides to apply.
1.Why can 5G help the farming?
A.Because it can carry more information.
B.Because it can be equipped with sensors.
C.Because it can disrupt a lot of industries.
D.Because it can be installed in rural areas.
2.What did farmers do firstly if they wanted to use Me+Moo?
A.They founded a tech company.
B.They let the cows wear 5G-connected collars.
C.They kept cows behaving normally.
D.They made sure the cows were checked often.
3.According to FAO, how will the world solve the food problem?
A.People should control the rising population.
B.People should find more and more land.
C.People should turn to the new technology.
D.People should learn to get more money.

Bees play a vital role in the world. Unfortunately, bees are dying by the second.
The main purpose of bees is to make honey. Honey, shockingly, does not exist for human consumption, it is essential to the insects. Honeybees store honey in their hives (蜂巢) in order for the bees to have energy for their flight muscles and for heating the hive during the winter period. They collect pollen (花粉) which supplies protein for young bees to grow.
According to Honey, com, the increased production and quality of agricultural crops as a result of honey bee pollination is valued &t more than1 $14/ 6 billion per year. These insects are responsible for over 70 of the fruits and vegetables we eat today, including apples, grapes, coffee, beans, and broccoli.
So if they are so valuable to agriculture, why do they keep dying off? A key suspect seems to be pesticides (农药). Honeybees who are exposed to pesticides result in the damage to their neurological (神经的) functions, specifically memory or behavior. And that's why the majority of worker bees disappear and leave behind a queen, plenty of food and a few nurse bees to care for the remaining immature bees and the queen. There are several other causes to the decline of bees, including the destruction of natural habitat, like woodlands, forests, and other habitats for bees. Climate change is also a factor in the decline of the wild bee population.
Actually, there are a variety of methods to help the bee population grow. One way is to start your own organic garden by planting bee-friendly plants. Pesticides are used in both industrial practices and even in your home, so it is best to find organic seeds and weed killers.
