1 . Young Alison Teal never rode in a pushchair or played on a swing on the playground.       1     She saw the view from atop a peak in Peru at just two months old on her mom’s back. They traveled the globe staying not at five-star hotels but in a six-foot-wide tent. From mountaintops to jungles, they immersed (沉浸) themselves in local nature and culture.

Between journeys they would return home to quiet part of the Big Island of Hawaii. Her front yard was the ocean, and her friends were dolphins.       2     Alison would dive into the water and release a sea leaf. A dolphin would catch it on its nose and throw it to the next player. Over the years, the dolphins grew to trust Alison.       3     She let them take the lead in their interactions. After studying at the University of California, Berkeley and then graduating from a film school, Alison continued her world travels. Her adventurous experience and survival skills landed her a spot on the reality show Naked and Afraid, in which she and a co-constant had to live on a deserted island for 21 days. Alison’s deep knowledge of how to live in a wildness saved the pair.       4     “After that, I couldn’t ignore our plastic problem,” says Alison. “I decided to protect our greatest resource, the ocean.”

Along with sharing her mission with her Instagram followers, the conservationist gave a TED talk on her discover.       5     Besides, she helped ban plastic bags in California. Her book, Alison’s Adventures: Your Passport to the World, is filled with travel tales and environment lessons. Alison believes all of us can make changes to protect the Earth.

A．How did Alison become a filmmaker?

B．What was their way of playing catch?

C．She launched a line of recycled surfboards.

D．At an early age, she began exploring the world.

E．Therefore, they approached her whenever she was in the water.

F．She was mostly home-schooled as the family traveled the globe.

G．But what shocked her was the amount of rubbish that washed up on the shore.

2 . Plastic is low-cost and long-lasting. It is not easily degraded(降解) because natural degradation processes can’t deal with its chemical components(成分). It takes in other ocean-present harmful substances. These chemical and dangerous components are gradually got into the atmosphere with additives such as color, which turns out to be really harmful when the plastic breaks down.

The design and development of new plastic products was sped up after World War II. Life without plastic seemed impossible in the modern age. But even though plastic was quite convenient, the dark side of it was seen as people began to enjoy the throw-away community. Many plastic products, such as plastic bags, have a lifetime of a few minutes to hours. However, they’ll stay in the environment for hundreds of years. We are destroying the very world that nurtured us.

Just 9% of plastic has been recycled and 12% burnt after production rose in the 1950s, which leave s about 79% of the 8.3 billion tons produced sitting in landfills(垃圾填埋场) or damaging our fields, oceans, and waterways. And each year the plastic ends up as contaminants. So to beat plastic pollution, we need to work together.

While plastic burning reduces the amount of waste dumped into oceans and lands, harmful gases are still produced, which also leads to greenhouse gases. However, if we make a firm decision and use modern waste management methods, we will be able to create a safe and healthy world. It is high time that we as responsible global citizens, took on the duty of protecting our environment and made great effort in saving our mother earth, instead of just leaving everything to our government. So, ladies and gentlemen, let’s make a promise to successfully deal with plastic waste and protect our world from all possible risks.

3 . Earth Day falls on April 22 each year to inform people about environmental problems and inspire them to act. It first came into being in 1970, followed in 1972 by World Environment Day. It has been celebrated ever since, slowly but surely picking up steam. Interestingly, it remained a grassroots affair for 20 years before spreading out to 140 countries in 1990. Now, it is celebrated around the world. Humans still face many challenges, such as climate change and plastic pollution. But we can all make a difference.

When Claire was in the seventh grade, she learned about plans to expand and modernize her middle school. As a follower of Earth Day, she wanted to help. Claire asked the school board to add solar panels to the project because, she explained, clean energy would contribute to a truly modern school, and help her school pursue sustainable development.

The board liked the idea but said it could contribute just $25,000, one-fifth of the cost. So Clarie turned to the community, looking for a solution. Her friends and neighbors shared her enthusiasm. Soon Claire organized a group of kids and adults, who set to work raising the rest. They wrote grant (拨款) requests, put on a talent show and asked for donations, even going door-to-door for them at Halloween. And they appealed to charitable foundations too. One donated more than half the cost!

After two years of hard work, the group paid for the solar panels, which now supply one-fourth of the school’s electricity needs, saving the district thousands of dollars. “My favorite part about this project was that one person could start something small and then the project could grow and have a big impact on the community,” Claire said “There are always going to be barriers and hard parts. When there’s a challenge presented to you, use it as a learning moment and an opportunity to overcome it.”

You can be a hero for the environment, so find out what can be recycled where you live.

4 . 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。

For those consuming Asian food, using chopsticks     1    (be) almost second nature. About 20 to 33 percent of people in the world use chopsticks     2     a daily basis. Not all of those are disposable (一次性的),     3     no doubt many are.

Felix Böck, a student at the University of British Columbia, was eager to find a way to recycle wood from construction projects, and he had a particular interest in bamboo. One day he found a drawer in his friend’s house     4    (fill) with disposable bamboo chopsticks, and an idea hit him.

He decided to give     5     second life to disposable chopsticks by making them into home     6    (decoration) or other accessories (配件). He told the idea to restaurant owners,     7    (convince) them to install recycling bins in their restaurants. He cleaned the chopsticks, pressed them into square pieces and coated them with glue.

5 . Tropical (热带的) forests could become so hot that some kinds of leaves will no longer be able to conduct photosynthesis (光 合 作用), according to a study. The photosynthetic machinery in tropical trees begins to fail at about 46.7℃ on average. The research suggests that forests may be nearing dangerous temperature sooner than expected. Models predict that once we hit a global temperature increase of 3.9℃, these forests might experience mass leaf damage.

Chris Doughty, an associate professor at Northern Arizona University and the lead researcher of the study, said the leaf-warming experiments had revealed a nonlinear rise in temperatures. “We were really surprised that when we warmed leaves by 2, 3 or 4℃, the highest leaf temperatures actually increased by 8℃. This shows a concerning nonlinear feedback that we were not expecting.” said Doughty. “If we adopt a do-nothing response to climate change and tropical forest air temperatures increase by greater than 4℃, there could be massive leaf death.” he added.

Avoiding high emissions (排放) in the first place is key to stabilizing temperatures. “We should do all we can to avoid high-emissions. Under low-emissions, almost all tropical forest tree leaves can avoid death from overheating and the trees will survive,” said Simon Lewis, a professor of global change science at University College London. “Yet what the study doesn’t look at is heatwaves. We still might see tree deaths from overheating for limited periods during heatwaves under lower emissions.”

Researchers suggest that the damage is not yet unchanged. “Vote for people who are serious about addressing climate change and transferring to low-carbon economies, ”Disney, one researcher, advocated. More generally, we can all recognize the importance of supporting those countries and people who live in and rely on tropical forests economically, But the serious changes to tropical forests don’t just affect the local people it’s a global issue.

6 . Zologial Sociey of London(ZSL), which runs London Zoo, brought together 16 scientists from different organizations to make a full “heath heck” on 215 miles of the Thames. The results of the first-ever State of the Thames Report have been shown to the public and there’s both good and bad news for London’s main waterway.

First up, since the Thames was pronounced “biologically(生物学地)dead” in1957, the number of animals and plants growing in and around the river has increased greatly. Natural habitats(栖息地)are also on the increase, some of which can help in the fight against climate(气候)change.

It’s not all good news though—like everywhere else, the Thames is influenced by climate change, mainly through changes in water temperature and sea levels. The Thames is increasing in temperature at an average(平均数)of 0. 2℃ each year, changing the natural environment.

Water levels are also rising in the Thames—at Silvertown. There has been an average increase of 4. 26 mm per year since 1990, which makes London more likely to be flooded.

As with pretty much everywhere on Earth, the Thames needs climate change to be stopped in order to make itself a living river in the future.

The Environment Agency has put together the Thames Estuary 2100 Plan which sets out a long-term plan for dealing with the influence of rising sea levels for the rest of this century, in order to protect London from floods.

James Brand, Thames Estuary 2100 Advisor at the Environment Agency said, “We are glad to support the State of the Thames Report. If we are going to stop climate change, nature needs to be at the heart of our activities, both in slowing the pace of future change and dealing with the changes that we are already seeing.”

A．They did an examination of it.	B．They gave an introduction to it.
C．They brought new animals to it.	D．They organized a clean-up of it.

2. What is Paragraph 2 mainly about?

A．The way animals are raised.	B．The development of natural habitats.
C．The meaning of “biologically dead”.	D．The welcome changes to the Thames.

3. What has happened to the Thames?

A．It has caused many floods.

B．Its temperature has been rising.

C．Its plants have become fewer and fewer.

D．It is home to a smaller number of animals.

4. Why was the Thames Estuary 2100 Plan made?

9 . Do you know how much India struggles to gather the waste plastic water bottles? According to a Central Pollution Control Board (CPCB) report from 2012, India generates 15, 000 tonnes of plastics a day, of which the gathered ones only achieve 60%. The trashed-but-not-gathered plastic waste leads to land and water pollution. posing serious threat to the environment.

After seeing that, Ankur Chawla, a drink expert, undertook research to find a solution, after which he realised the biggest problem the country faced was disposing of plastic waste. To address it, he wanted to come up with a solution where they do not add to the problem of waste. Fortunately, Ankur was not alone. He met Bhrigu Seth who was into green farming. Both of them found that they shared a common goal and it didn’t take long for them to draft a plan of action. It is estimated that over 90 percent of aluminium(铝) drink cans in India are recycled. Instead, 70 percent of the cans are manufactured through recycled waste. After going through challenges at hand, the pair made up their minds.

Before taking the next step. both co-founders visited five-star hotels and took samples of water in aluminium cans, asking them whether they would give it a shot if something like that comes in the market. The pair received an overwhelmingly positive response. They then determined to launch Responsible Whatr, natural spring water drink packed in an aluminium can to solve the problem of waste plastic water bottles.

As one of India’s first natural spring water drink, Responsible Whatr offered an environmentally friendly and endlessly recyclable aluminium can. It’s a non-alcoholic drink that was launched with a vision for an eco-friendly future and an agenda to reduce single-use plastic pollution.

Going forward, Ankur and Bhrigu aim to cooperate with airports and ecommerce gates which would help them in directly reaching the homes of high networth individuals (HNIs). They also plan to tie up with corporate firms and cinema halls and join hands with NGOs that are fighting for the conservation of beaches and oceans.
