4 . With climate change continuing to worsen, our situation is beginning to feel increasingly serious.     1     Is it right? Maybe not.

Techno-optimism is one of the greatest misconceptions when it comes to solutions to ensure our future. It can be defined as a belief that future technologies will solve all of our current problems. This definition reinforces (强化) the idea that there’s no reason to panic or change our current energy-intensive lifestyle. All society needs to do is look to green technology to work its magic.     2    

One of the best examples of this optimistic misconception is the electric car. Despite being highly regarded as an eco-friendly way to get around, electric cars are not the end for the future of transport. Batteries in electric cars use chemical elements which we could be seeing a shortage of by the midcentury.     3     Techno-optimism has led many to believe that if everyone just switched to driving electric vehicles, we would be making incredible steps towards sustainability. However, the reality is that the amount of resources and energy needed to produce enough electric vehicles for everyone is not even remotely sustainable.

    4     Investing in public transportation and moving away from individually owned vehicles. Producing fewer cars. Improving recycling practices of old batteries. The solutions we seek should not be rooted in new technology, but be about changing the way our society functions.

Techno-optimism puts too much emphasis on technology and not enough on what we can do right this minute. Unfortunately, people seem to like the picture that techno-optimism paints.     5     It is important to understand that the problem begins when we see those technologies as a way to make our current lifestyles eco-friendly. Until we are ready to face the need for a less complex life, we cannot make true progress towards sustainability.

A．So where should we look for answers instead?

B．The modern world’s simple solution is technology.

C．Moreover, they are more energy intensive to produce.

D．Is it a trap that many people have fallen into in recent years?

E．Unfortunately, this is an incredibly dangerous opinion to hold.

F．Despite any technology, we as a whole are not living sustainably.

G．Nevertheless, the truth is, we need a widespread change in our lifestyles.

6 . Last fall my class and I went through an exercise to help the students understand how the world might address the climate crisis. Several things surprised the students. One was that nuclear power doesn’t help.

But many people think nuclear energy is going to be the climate solution. President Obama included federal loan guarantees for nuclear power in his energy plan, in the hopes of jump-starting construction and gain Republican support. (It did neither.) If I post something even faintly skeptical about nuclear power on Twitter, its advocates come out in force, accusing me of being a conservative, or worse.

What is it about nuclear energy that makes its advocates so determined in the face of what should be discouraging facts? After all, unlike futuristic, untried technologies, we have plenty of facts about this one, and most of them are discouraging. The first American civilian nuclear power plant broke ground in Pennsylvania in 1954, around the same time that physicist John von Neumann predicted that, within a few decades, nuclear power would be so efficient as to make energy “free—just like the unmetered air.” That didn’t happen. Today nuclear power remains the most expensive form of electricity generation in the U.S. -typically costing twice as much as a fossil-fuel-based plant.

Why then do so many people keep coming back to it? I think it’s the same reason people turn to geoengineering(气候工程) and nuclear fusion(聚变) (which has been “just around the corner” since 1943): the promise of technological progress. For the past century or more, humans have been accustomed to technological breakthroughs that made life easier, more comfortable and more entertaining. But climate change throws future advancement into doubt. It breaks the promise of progress. No matter what we do, we are going to be paying for the costs of our historical and current use of fossil fuels.

So we turn to technofideism- the faith that technology will save us. Perhaps it will. But perhaps it won’t, and our long-standing patterns of behavior will have to change along with our technology. And that’s a hard pill to swallow.

1. What is paragraph two mainly about?

A．Nuclear energy has lots of advocates.

B．The supporters of nuclear energy are unwise.

C．President Obama failed to conduct his energy plan.

D．Doubtful remarks about nuclear power will attract criticism.

2. What is the purpose of mentioning the first American civilian nuclear power plant ?

A．To show it was a groundbreaking project.

B．To compare nuclear power and fossil-fuel energy.

C．To prove nuclear power didn’t live up to people’s expectations.

D．To indicate we need futuristic, untried technologies rather than nuclear.

3. Why do people turn to technofideism?

A．Because it can cut down the current use of fossil fuels.

B．Because we tend to trust technological breakthroughs.

C．Because people are skeptical about the promise of technology.

D．Because geoengineering and nuclear fusion have set a good example.

4. Which one is the writer’s attitude to nuclear energy?

A．Optimistic.

B．Hesitant.

C．Aggressive.

D．Negative.

8 . Despite years of drought and water-saving policies, Californians continue to put a lot of clean, drinkable water into yards to keep the greenery alive. Now, however, Southern California officials have carried out very strict limits on outdoor water use in response to a water shortage emergency. So you may need to find other ways to keep your plants from drying in the summer sun.

How about watering them with grey water instead of clean water? Grey water is the water from showers, bathtubs, washing machines — anything that’s not filled with human waste, food or poisonous chemicals. With the right measures, grey water can be fine for most plant life.

If you’re a typical Southern Californian, you’re throwing a lot of grey water into the sewer system. Every load of clothes you wash leads to roughly 15 to 40 gallons of it, depending on your washer’s design and efficiency. Over the course of a year, thousands of gallons of soapy water ran away. That’s enough to keep a number of trees and other plants happy. And if you’re really ambitious, you can build a system that carries all of your horned grey water to the roots of your grassland, thus making your non-native grass in your yard watered regularly.

Some critics, the Los Angeles Sanitation and Environment Bureau, see grey water recycling as environmentally risky, damaging public wastewater recycling efforts and uneconomic. However, other local agencies across the state, including the Los Angeles Department of Water and Power, actively endorse grey water projects as a way to reduce water use. Supporters admit that the projects carry some risk and require great efforts, but insist that they can save clean water and help your plants.

1. What can be inferred from paragraph 1?

A．California is very rich in clean and drinkable water.

B．There is a lack of water-saving policies in California.

C．Outdoor water use in California will be strictly controlled.

D．Different ways to save water have been adopted in California.

2. What’s the purpose of paragraph 3?

A．To summarize the benefits of using grey water.

B．To provide reasons why grey water should be used.

C．To make a prediction about the future of grey water.

D．To introduce some new ways to save drinkable water.

3. What’s the attitude towards the use of grey water according to the last paragraph?

A．Negative.

B．Indifferent.

C．Positive.

D．Objective.

4. What does the underlined word “endorse” mean in paragraph 4?

A．Oppose.

B．Promote.

C．Abandon.

D．Recover.

9 . According to the American Chemistry Council, in 2018 in the United States, 27million tons of plastic ended up in landfills compared lo just 3.1 million tons that were recycled. Worldwide the numbers are similarly bad, with just 9% of plastic being recycled according to a recent OFCD (Organization for Economic Co-operation and Development)report. The statistics are even worse for certain types of pastie. For example, out of 80,000 lens of polystyrene containers generated in the United States, a negligible amount(less than 5,000 tons) was recycled.

Now, researchers at the University of Queensland have found that a species of worm with an appetite for polystyrene could be the key to plastic recycling on a mass scale. They discovered that the Zophobas morio also called “super-worm” can eat through polystyrene, thanks to a bacterial enzyme (酶) in its “Stomach”. Dr. Chris Rilke and his team from UQ’s School of Chemistry and Molecular Bioscience fed super-worms different diets over a three-week period, with some given polystyrene, some outer skin of grain separated from the flour, and others pul on a fasling diet.

“We found the super-worms fed a dict of just polystyrene not only survived, but even had slight weight gains,” Dr. Rilke said. “This suggests the worms can get energy from the polypropylene,most likely with the help of their internal micro-organisms. They are like mini recycling plants, tearing up the polystyrene with their mouths and then feeding it to the bacteria in their ‘stomach’. ”

Co-author of the research, PhD candidate Jiarui Sun, said they aimed to grow the bacteria in the lab and further test their ability to break down polystyrene. “We can then look into how we can upgrade this process lo a level required for an entire recycling plant,” Ms. Sun said.

1. Which of the following best describe the current plastic recycling?

A．Inefficient.	B．Unpredictable.
C．Inconsistent.	D．Unconventional.

2. What is the Zophobas morio capable of according to the research?

A．Turning polystyrene into energy.

B．Feeding the bacteria in the mouth.

C．Eating through any type of plastic.

D．Gaining weight on a fasting dict.

3. How will those researchers continue the research?

A．By testing different abilities of the bacteria.

B．By experimenting with large-scale production.

C．By establishing a modern recycling factory.

D．By growing and breaking down the worm.

4. What is the text mainly about?

A．The severity of plastic pollution.

B．The future of recycling industry.

C．Super-worm’s commercial success.

D．Super-worm’s ability to digest plastic.

10 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Preserving more habitats for China’s giant pandas is providing a giant payoff.    1    (save) the giant panda from dying out isn’t just good for the panda, but it’s also good for economy, a new analysis by an international team of scientists shows.

The results,    2    (publish) in the magazine Current Biology, stress the economic bene-fits that go hand in hand with environmental protection. Giant pandas are one of the    3    (rare) species around the world. But pandas fell on hard times in recent decades, thanks largely    4    human encroachment (侵入). In 1980 alone,many habitats    5    (destroy) artificially, and in 1990, their habitats covered only 12,340 square kilometers,     6    is a major threat to the pandas in large part because bamboo, their main food source, is so low in nutrients that they must wander a lot of land in order to find and eat enough of it.

Because of this, Chinese officials began making significant efforts to save the panda from     7    (extinct), establishing more reserves and increasing the reserve area three times. Panda numbers    8    (gradual) began to recover, hitting 1,596 in 2000 and 1,864 in 2010.

“    9    is clear that society’s investment (投资)    10    (start) to pay off so far in terms of panda population recovery,” the study authors wrote.
