21、   Zika virus. Malaria. West Nile virus. Dengue fever. Have you ever heard of these illnesses? If so, you likely know what they all have in common. These are a few of the diseases spread by one of the greatest pests known to humankind一the mosquito.

Much of the time, mosquito bites are just itchy. Nothing ruins a backyard barbecue faster than a mass of these bloodsucking insects. However, some mosquitoes carry viruses that cause deadly ilnesses. In fact, some experts say mosquitoes are a bigger threat to human life than any other organism.

Over the centuries, mosquitoes are thought to have caused the deaths of 52 billion people. That’s half the people who have ever lived on Earth! Even today, ilnesses spread by mosquitoes kill more people each year than war does.

It should be no surprise that many people would like to get rid of mosquitoes. What if we could wipe out the entire mosquito population? No more malaria. No more Zika. No more itchy bumps after a summer day spent outdoors. Doesn’t that sound great?

Not so fast. Sure, some species of mosquitoes harm humans. But others don’t pose any threat at al! In fact, some of these mosquitoes play important parts in their ecosystems. Let’s look at a few ways.

Many of our Wonder Friends already know that bees play an important part in pollination（授粉）. It turns out, mosquitoes do, too! Most mosquitoes actually drink nectar（ 花蜜） instead of blood. When they do so, they help pollinate the plants they feed on.

It’s also important to remember that even mosquitoes are part of an ecosystem. Without them, the food chain would be disturbed.

Adult mosquitoes are a food source for bats, birds, spiders, and small mammals. Without them, these animals would need to find something else to eat. Some experts even think mosquitoes could be used to help humans.

【1】What do Zika virus, Malaria, West Nile virus, and Dengue fever have in common?

A.They are all pests from the wild forest. B.They can not be cured by human beings.

C.They can all be spread by mosquitoes. D.They are all caused by bacteria.

【2】What does the underined phrase in the fourth paragraph mean?

A.Kill something completely. B.Bring up in large numbers.

C.Control something completely. D.Rely on something completely.

【3】What is the author’s attitude towards mosquitoes?

A.Positive. B.Negative. C.Critical. D.Objective.

【4】What may the author continue to write about in the following?

A.How mosquitoes are harmful to human beings.

B.How mosquitoes are helpful to human beings.

C.How mosquitoes cause various ilness to mankind.

D.How mosquitoes are eaten by small mammals.

22、   Large oceangoing vessels like oil tankers and cruise ships produce noise that travels long distances underwater. That audio pollution can disturb the sounds that marine mammals, fish and other animals use to communicate.

Emily Carter, a sensory ecologist from University of Exeter wondered whether ship noise might also be harmful to animals that don’t rely on sound for communication. For example, young shore crabs that use camouflage (伪装) to hide from predators. “So they can actually change their color to match whatever it is that they’re sitting on, basically to make it harder for predators to find them.” Carter explained.

She suspected that stress from ship noise might affect the change process. To find out, she and her colleagues collected shore crabs with dark shells and brought them back to the lab. They placed the crabs in tanks full of white small stones. An underwater speaker in each tank played quiet natural sounds at all times. One group of crabs also heard loud natural sounds every hour. But another group was subjected to hourly recordings of large ships.

Carter says shorebirds, which eat the crabs, can see UV light, so she used ultraviolet (紫外线) photography to determine how well the crabs blended into their new habitat over time.

“Through the eyes of a shorebird — so through bird’s perspective — were they camouflaged? Weren’t they camouflaged? How obvious would they be?”

After eight weeks, the crabs that heard only natural sounds had become much lighter and were well camouflaged. But the ones that were exposed to the ship noise didn’t change color as much. And then, as a result, they weren’t as camouflaged at the end of the experiment. So they’d be much more manifest to predator.

Carter says the stress caused by ship noise may affect hormones that regulate color change in crabs or destroy the energy needed to make the change efficiently. The research not only puts a spotlight on the unintended consequences of noise pollution, but is a reminder that too much stress isn’t just bad for people — it can also be deadly to wildlife that needs some peace and quiet.

【1】Why is ultraviolet photography used in the experiment?

A．To scare away shorebirds.

B．To kill the bacteria in crabs’ new habitat.

C．To test the effectiveness of crab’s camouflage.

D．To monitor the shorebird population in nighttime.

【2】What does the underlined word “manifest” mean in Paragraph 6?

A．Avoidable.

B．Noticeable.

C．Changeable.

D．Adjustable.

【3】Which of the following is true?

A．Carter conducted the experiment on her own.

B．The crab that heard natural sound lost some weight.

C．Carter created three kinds of living environment for crabs.

D．The crab that heard ship noise slightly changed their color.

【4】What did the research find?

A．Noises do harm to us people.

B．Wildlife needs a quiet environment.

C．Crabs aren’t camouflaged in new habitats.

D．Stress can change the hormones in humans.

23、   When a laptop or smartphone battery starts losing its power, the only options are to buy an expensive replacement, or just keep it plugged in all the time. But a woman Mya Le Thai may have found the answer to this problem.

Thai was frustrated that the batteries for her wireless devices degraded over time, until they failed to charge fully. She did not like having to keep her laptop connected to an electrical outlet to keep it powered on. So, she decided to do something about that problem. At first, she and her team at UC Irvine thought about inventing a new battery. But as they experimented, Thai discovered something that might permit lithium-ion(锂离子) batteries to last forever.

Lithium-ion batteries power most wireless devices. Over time, the batteries lose the ability to hold a charge. Most of these batteries have a life span of about 7,000 charging cycles before they die. One of the reasons lithium-ion batteries degrade is their use of nanowires to carry electricity. Nanowires are extremely thin. A human hair is thousands of times thicker, for example. Nanowires are extremely efficient carriers of electricity, which makes them useful in batteries.

But, Thai had a theory-the nanowires might last longer if covered with a gel(凝胶). She and her team tested this theory. “It was a long process and a lot of work,” Thai said. The team tried many coverings for the wires. PMMA, a type of plastic, was one of them. The nanowires were coated with PMMA and cycled through charges 200,000 times. The PMMA-coated nanowires showed no evidence of damage. The results suggest that batteries could last forever, without losing charging ability.

Thai hopes to continue her research to understand why this gel works so well and to see if any other gel could create better results and she is enjoying the publicity about her discovery. She said she never expected her research to get media coverage. “It’s kind of cool,” she said. “I’m really glad people are showing interest in my work and not just in the work itself, but also in technology and energy.”

【1】What can we infer about nanowires?

A.They last only 7,000 charging cycles. B.They are too weak to carry electricity.

C.They are not suitable to use in batteries. D.Their thinness is a cause of batteries degrade.

【2】What might be Thai and her team’s breakthrough?

A.Coating nanowires in gel. B.A new kind of battery.

C.New materials for batteries. D.A new way of charging batteries.

【3】What may be the best title for the passage?

A.The options of batteries for wireless devices B.A woman invents a life-long battery.

C.Mya Le Thai discovered Nanowires D.The reasons for batteries degrading

24、Loneliness is significant mental health concern and can raise risk of death by 45% and contact with nature in cities significantly reduces feelings of loneliness, according to a team of scientists.

The study is the first to assess how the environment can affect loneliness. It used real-time data, collected via a smartphone app, rather than relying on people’s memory of how they were feeling.

The research found that feelings of overcrowding increased loneliness by an average of 30%. But when people were able to see trees or hear birds, feelings of loneliness fell by 28%. Feelings of social inclusion also cut loneliness by 21% and when these feelings coincided (巧合) with contact with nature, the beneficial effect was boosted by a further 18%.

The findings pointed to interventions (干预) to reduce loneliness. The researchers said, “Specific measures that increase social inclusion and contact with nature should be taken, especially in thickly populated cities.” Time spent in nature is known to boost well-being (健康), with woodland walks estimated to save the UK at least £185m a year in mental health costs, for example.

The research collected data from urban citizens across the world using the Urban Mind research app. More than 750 people provided 16,600 of these assessments. The participants were self-selecting and so did not provide a representative sample of the wider populations. But when the researchers took age, education, and occupation into account, the benefits of nature contact and feelings of social inclusion on loneliness remained strongly statistically significant. Johanna Gibbons, part of the research team, said, “Cities are probably the only habitat that is increasing at a high rate. So we should be creating urban habitats where people can thrive.”

【1】How was the research conducted?

A．By relying on people’s memory.

B．By surveying 750 urban participants.

C．By collecting data through a smartphone app.

D．By checking a worldwide representative sample.

【2】What can we learn from Paragraph 4?

A．Many big cities take the lead in the research.

B．Time spent indoors improves people’s well-being.

C．Woodland walks greatly reduce social contact with people.

D．Interventions to reduce loneliness benefit the UK financially.

【3】What can be inferred about the research?

A．It offers a wide range of samples globally.

B．The findings are remarkable in terms of statistics.

C．The carefully selected participants are reliable.

D．Many factors are considered except education.

【4】What’s the text mainly about?

A．The problems of living in big cities.

B．Developing urban habitats at a high speed.

C．Research on how to get rid of loneliness in nature.

D．Reducing loneliness in cities through contact with nature.
