Litter is everywhere，doing great harm     1     the environment and life on our planet.Jeff Kirschner，who wants to build a litter-free world，started a global community named Litterati     2       (settle)this problem.

The story began with his 6-year-old daughter.One day they were going on a hike when the girl noticed a     3     (break)plastic tub(浴盆)in a river.She said，“Daddy，that doesn’t go there.”That took Kirschner by surprise.He，like many adults，had become so used to the rubbish around them that he hadn’t given it a second look.    4     his daughter said reminded him of the serious problem our planet faces.

Jeff started to take       5    (act).He created Litterati，an app that makes it fun to pick up litter.The idea is       6    (fair) simple:Spot a piece of trash，take a photo，post the photo online and then put the litter into dustbins.

    7     (see)that Jeff was keeping a record of the positive impact he was having on the planet，people worldwide started participating.Up to now，over 2，500，000 photos posted by 3,500 people from over 40 countries     8     (find)their way to Litterati’s digital landfill.

Litterati is more than an app.It is a highly     9     (effect)solution to a pressing issue.Wherever you live，whatever you do and       10     you are，join Litterati to make the world a cleaner and healthier place to live in.

2 . Not only does the use of plastic water bottles hurt your wallet, it also increases pollution and wastes energy and water. Only 23% of all plastic in America ends up in a recycling bin, meaning over $ 1 billion worth of plastic is treated as rubbish a year. Recently, Skipping Rocks Lab has invented a kind of water bottle called Ooho.

It is a convenient, clear water bottle that can either be drunken or eaten. To drink it, you can either peel off the membrane (薄膜) or tear a hole in the membrane with your teeth to pour the water into your mouth. To eat it, you simply put the whole bottle in your mouth. One problem the scientists have run into is how to ship large amounts of Ooho bubbles(水泡) without arriving with a very wet truck. However, they have attempted to package units of individual bubbles together inside a larger and thicker membrane. It is targeting large outdoor events, such as marathons, music festivals, and sporting events, where tons of plastic bottles are used, and frequently left behind as litter. And too much plastic is sure to do harm to the environment, which could account for their purpose of such a new invention.

The team has been working for the past two years to develop the technology and materials needed to produce Ooho; they have recently applied a patent for their new advancements. The price for an individual bubble or a unit of bubbles has not been set yet, but they cost about two cents to create a unit, which is cheaper than plastic bottles. It has appeared at events in London, San Francisco, Boston, at conferences, festivals, and so on.

Ooho is catching many people’s attention and has raised over $ 1 million and gained 1,000 investors in only three days. It is mostly being sold at events at the moment to keep the consumer’s interest while the production machine is getting up and running. It is quickly making a rise,so keep an eye out this year for these bottles of the future.

A．It’s sold.	B．It’s recycled.
C．It’s buried.	D．It’s wasted.

2. Why did the team invent Ooho?

A．To make a profit for a company.	B．To protect the environtnent.
C．To make people eat as they drink.	D．To reduce the cost of plastic bottle.

3. What can we infer about Ooho from the text?

A．It is easy and safe to ship it in large amounts.

B．It has become popular since it began to be sold.

C．It might be sold at a lower price than plastic bottles.

D．It cost the team a lot of money to develop the technology.

4. What does the author really want to say in the last paragraph?

A．Ooho is to be a success in the future.

B．Ooho is being supported by smart people.

C．Ooho is taking the place of plastic bottles now.

D．Ooho is being produced to attract more investors.

3 . The idea that having narrow local focus leaves little room for anything but a selfish mindset is a misconception, according to a new study that found that concern for local affairs could help with global environmental conservation.

You might have heard of NIMBY which means “not in my back yard” and describes an individual or group opposed to a new addition to the neighborhood, typically a factory, roadway or power station. Nimbyism and parochialism(眼界狭小), which is a focus on a local area,   can go hand in hand, and there are concerns that parochialism paves the way for prejudice, narrowmindedness, and selfishness.

But researchers found the exact opposite to be true in a new study published. The researchers argue that positive parochialism can inspire a larger awareness of global environmental problems and encourage people to action.

“We did not find evidence that parochialism was necessarily negative and inward -looking,” said Patrick, a researcher for the study. “It can be those things, but there's no necessary conflict between feeling connected to your local area and feeling connected to the wider world. ”

For the study, the researchers reviewed documents from the 1987 Parish Maps project. The researchers showed how the Parish Maps project also demonstrated a passion for the environment and conservation. The researchers say that the Parish Maps project is a strong example of “positive parochialism”, and shows that thinking locally can influence a global mindset.

“For a long time,   it has been generally agreed that if we want people to think about global affairs they need an international worldview-but this may not be the case,” said Patrick. “Given where we are now in terms of trying to encourage people to make changes to help the environment, positive parochialism offers something that has been overlooked.”

1. Which behavior can best illustrate NIMBY?

A．Criticizing a friend for his selfish action.

B．Accepting a proposal beneficial to locals.

C．Supporting a neighborhood construction plan.

D．Objecting to building an airport in the neighborhood.

2. Why does the author mention the Parish Maps project?

A．To explain how to protect the environment.

B．To offer an example of positive parochialism.

C．To encourage people to take part in the project.

D．To stress the importance of global mindset.

3. How does Patrick feel about “positive parochialism phenomenon”?

A．Appreciative.

B．Cautious.

C．Negative.

D．Puzzled.

4. What may be the best title for the text?

A．Parochialism, a better practice?

B．International view, more popular?

C．Thinking locally, acting globally

D．Bigger thinking, better environment

4 . A 2018 report found that food waste would increase by a third to 2. 1billion tons by 2030. Beyond the cost of the waste itself，thrown-away food generates a gas that contributes to climate change.

Home delivery meal kits(盒)can reduce food waste by more than two-thirds，but suppliers need to switch to reusable packaging to make them environmentally friendly.

Tailor-made meal kits cut waste by providing people with precise amounts of fresh ingredients(烹饪原料)for chosen recipes，meaning leftovers are minimized. But while the   delivery services score well on reducing food waste，buying the same food ingredients from the supermarket almost always saves energy overall simply because meal kits use so much single-use packaging. The good news is that if people have meals that are tailored for consumption，they won’t overbuy and have less food waste. They fine-tune the amount of food to what they will actually eat.

Meal kits can reduce transport emissions(排放)if people go to the supermarket less   frequently. If people only go and buy such goods as soap and toilet paper，they may only have to visit once every couple of months. A delivery truck can carry meals for a lot of people in the neighborhood. So dozens of car trips might be replaced with one truck trip.

However，study found that even if delivery meal kits reduced food waste to zero，they would still use up more energy overall than buying the same food from the supermarket unless the energy used for the meal kit packaging was cut by a fifth. The packaging is a killer if it’s single-use and thrown away，which can make all the environmental benefits lost. But if the packaging can be reused，if it’s glass bottles，like in the old days，we can get some benefits.

1. What can we learn about home delivery meal kits?

A．They can cut down on daily expenses.

B．They will totally solve the problem of food waste.

C．They can keep energy consumption to a minimum.

D．They will benefit the environment with reusable packaging.

2. What does the underlined word“fine-tune”in paragraph 3 mean?

A．Attach.	B．Adjust.
C．Raise.	D．Compare.

3. The author suggests carrying meals with a delivery truck to__________.

A．reduce transport emissions	B．save more food
C．shop only in the supermarket	D．shorten car trip distances

4. What’s the author’s attitude to meal kits?

A．Supportive.	B．Unfavorable.
C．Objective.	D．Indifferent.

5 . “Birds” and “airports” are two words that, paired together，don’t normally paint the most harmonious picture. So it really raises some eyebrows when China announces plans to build an airport that is for birds.

Described as the world’s first-ever bird airport, the proposed Lingang Bird Sanctuary(保护区）in the northern coastal city of Tianjin is, of course,not an actual airport. Rather，it's a wetland preserve specifically designed to accommodate hundreds-even thousands-of daily takeoffs and landings by birds traveling along the East Asian-Australian Flyway. Over 50 species of migratory (迁徙的）water birds，some endangered, will stop and feed at the protected sanctuary before continuing their long journey along the flyway.

Located on a former landfill site，the 150-acre airport is also open to human travelers.(Half a million visitors are expected annually.) However，instead of duty-free shopping，the main attraction for non-egg-laying creatures at Tianjin’s newest airport will be a green-roofed education and research center, a series of raised “observation platforms” and a network of scenic walking and cycling paths totaling over 4 miles.

“The proposed Bird Airport will be a globally significant sanctuary for endangered migratory bird species, while providing new green lungs for the city of Tianjin.” Adrian McGregor of an Australian landscape architecture firm explained of the design. Frequently blanketed in smog so thick that it has shut down real airports, Tianjin is a city---China’s fourth most populous----that would certainly benefit from a new pair of healthy green lungs•

1. The underlined phrase “non-egg-laying creatures” in Paragraph 3 refers to?

A．Visitors.	B．Designers.
C．Endangered water birds.	D．Planes.

2. What do we know about the airport according to the passage?

A．The airport will become a permanent home for birds.

B．Tianjin will win worldwide fame in the future.

C．Tianjin’s air quality will improve thanks to the airport.

D．Tianjin will be able to accommodate more people.

4. What is this passage mainly about?

D．Birds are no longer enemies to airports.

6 . 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。

New Yorkers were shocked in early December when a creature as big as a school bus     1     (surface) from the Hudson River. Over the next three days,    2     humpback whale (座头鲸) swam by several popular tourist destinations, where a journalist took    3    (photo) of the animal seemingly waving its tail at Lady Liberty.

Scientists say NYC0089, which hasn't been spotted in several weeks, has likely returned to deeper waters south of the Hudson. Still, the     4    (frequent) of whale sightings in the broader area has gone up rapidly in recent years.

“With these numbers increasing     5     (sharp), it's not surprising that you're seeing them in some unusual places,” says Brown — a biologist. Including the Hudson River and Staten Island.

Scientists say the     6    (rise) whale sightings are likely related to purer water and a brimming buffet of Atlantic menhaden, a fish favored by humpbacks, resulting     7     landmark environmental regulations     8    (pass) in the 1970s as well as New York city cleanup efforts.

“Seeing more whales in this area is a sign    9     the waters are cleaner and there's more food here for these whales,” Brown says. “It shows     10     we've been doing is working, so we need to keep doing that — and more — to protect these species.”

7 . The government's top Great Barrier Reef scientist says a third mass coral bleaching (珊瑚白化) event in five years is a clear signal that the marine wonder is “calling for urgent help on climate change. Corals can recover from mild bleaching, but severe bleaching can kill corals.

Prof Terry Hughes, director of the Centre of Excellence for Coral Reef Studies at James Cook University, surveyed 1,036 reefs from a plane over nine days in late March.

The marine park authority also had an observer on the flights. The survey has released   maps showing that serious levels of bleaching occurred in 2020 in all three sections of the   reef northern, central and southern. Some 25% of the reefs were seriously bleached-meaning that more than 60% of the corals on each reef had bleached.

The Great Barrier Reel has experienced five mass bleaching events-1998. 2002,2016, 2017 and 2020 -all caused by rising ocean temperatures driven by global heating. Hughes said there probably would not be the same level of coral death in the north and central regions in 2020 as in previous years, but this was partly because previous bleaching outbreaks had kill off the less heat -tolerant species The 2020 bleaching was second only to 2016 for severity(严重性), Hughes said.

Dr. David Wachenfeld，chief scientist at the Great Barrier Reef Marine Park Authority, told Guardian Australia "My greatest fear is that people will lose hope for the reef. Without hope there's no action. People need to see these bleaching events, They are clear signals that the Great Barrier Reef is alling for urgent help and for us to do everything we can”.

Measures to improve the ability of recovery of the reef include improving water quality, controlling outbreaks of coral-eating starfish, and research and development to improve the heat tolerance of corals. " However, climate change brings a new scale of impact unlike anything we have seen before. Thus, dealing with the climate problem is the basis for everything else to work, ” Wachenfeld said.

1. What does the underlined word “mild” in Paragraph 1 probably mean?

A．Serious

B．Strong.

C．Steady.

D．Slight.

2. What can we learn from Paragraphs2 & 3?

B．The survey was carried out on a plane by Hughes alone.

C．The 2020 bleaching killed off the less heat tolerant species.

D．The 2020 bleaching was worse than those of all the previous years.

3. We can infer from Wachenfeld’s words that people seeing the bleaching events .

A．have done everything they can for the reef

B．are sure to lose hope for the reef

C．will care more about the reef

D．will have no action at all

4. Which is the essential measure to improve the ability of recovery of the reef?

A．Improving water quality.

B．Making efforts to prevent global warming.

C．controlling outbreaks of coral-eating starfish.,

D．Doing research on the heat tolerance of corals.

9 . Scientists say a huge percentage of bird species are in danger because their habitats, or homelands, are disappearing.

Traditional migration paths take birds through countries that are not protecting the places for birds to stop, rest and feed. The scientists studied the migration or flight paths of almost 1,500 species. They decided that 91 percent of them passed through dangerous areas.

The major danger for migratory birds is development. Buildings and pavements have covered the places where birds stop and feed as they move from one part of the world to another. One of the scientists who worked on the study says “Many of these important places have been lost to land reclamation because of urban, industrial and agricultural land expansion”.

The problem, according to scientists, is that many of these small birds die along their migration paths because they don’t have a safe place to feed and rest. There is no place to restore their energy for the next part of their journey. Countries in North Africa, Central Asia and those along the coasts of East Asia are having the most difficult time in protecting land. The scientists say these countries do not have enough areas that are safe for birds. One species that doesn’t exist now is the Eskimo curlew. “Our world gets poorer every time we lose a species,” one of the scientists says.

The researchers say countries need to work together and come up with safe stopping areas for birds that pass through their boundaries. For example, one country might have preserved safe zones for migrating birds. But a neighbor country might not. A bird might die.

One scientist who is not connected with the report tells Los Angeles Times that while some habitats are changing, more work can be done to make urban areas safe for birds.

He says small changes, like planting more native plants or keeping cats out of the areas birds would be likely to use, could make a big difference.

1. What mainly caused the disappearing of birds’ habitats?

A．The decrease of awareness to protect birds.	B．Natural disasters.
C．Overuse of land by human beings.	D．The rising sea level.

2. What may be the main reason for many birds’ death on the way of migration?

A．Tiredness and hunger.	B．Beast attack on the ground.
C．Hunting of humans.	D．The long journey.

3. According to the last two paragraphs, how should we protect the migrating birds?

A．By keeping fewer cats or dogs.

B．By restoring their destroyed habitats.

C．By helping change the birds’ migration paths.

D．By preserving the ecological environments on their migration paths.

4. What is the author’s purpose in writing the passage?

A．To call on people to protect the birds’ habitats.

B．To analyze the reasons for disappearing of birds’ habitats.

C．To offer some solutions to the problem of birds’ habitats.

D．To tell us a huge percentage of bird species are in danger.

10 . Tips for Green Travel with Kids

Travelling doesn’t mean letting go of all the eco-friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids.

Booking nonstop flights whenever possible will reduce carbon emissions (碳排放). If the closest local airport doesn’t have nonstop flights to a certain place, check with other local airports to see if nonstop flights are available.     1    

It’s easy when travelling to pull in to fast food restaurants for snacks.     2     My kids love to help plan snacks. I let them create their own snacks for the trip at home.

    3     At the airport, keep your reusable bottles empty until you have passed through the security (机场安检区). Fill them up on the other side of the security checkpoint. Single-use plastic water bottles create unnecessary waste and the plastic can be harmful to your health.

    4     In addition, opening a few windows and turning off the air conditioner (空调) are also good ways to save energy. You should also help your children keep their good, green habits while travelling. Sometimes vacation can mean more than one shower each day-once in the morning and again after getting out of the pool. Pay attention to the number of showers (淋浴) and the length of showers.     5    

A．Walking is good for your health.

B．Try to cut back to save water and energy.

C．But you can pack healthy food from home.

D．Travelling is a great chance to introduce your kids to the world.

E．Reusable water bottles are easy to bring along wherever you travel.

F．Save energy by turning off the hotel room lights when you head out for the day.

G．You might have to drive a bit farther, but saving on carbon emissions makes it worthwhile.
