三、阅读单选
Plastic snow falls from the sky.
When you think of the Arctic(北冰洋), you may imagine an icy land of white snow. And some people may imagine it as the last really clean place left on Earth. In fact, we have polluted the deepest oceans with plastic rubbish, and now, CNN says, "It's the Arctic's turn."
German scientists have recently found microplastics in Arctic snow. Microplastics are pieces of plastic smaller than 5 millimeters. Sadly, the scientists found 1,800 pieces of microplastics per liter(升) of snow. That may cause terrible air pollution.
How is plastic pollution reaching the Arctic According to scientists, "It's clear that most of the microplastics in the snow come from the air. They fall off plastic objects and are moved by the wind. They mix with ice in the air and fall to the ground as snow."
Are they bad for us We do know that our bodies cannot take in "large" pieces of microplastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time, which can be bad for our health.
Microplastics have also been found in rivers and oceans around the world. Research has found that they flow over long distances and into our oceans, damaging ecosystems(生态环境) along the way. When we wash clothes with plastic fibers(纤维), they start in our wastewater. The wastewater then flows into rivers and out to sea. They are eaten by sea animals there. If people then eat these animals, it means that we're eating the plastic as well.
31．According to the passage, the underlined word "microplastics" are pieces of________.
A．plastic bigger than 5 millimeters B．metal smaller than 5 millimeters
C．plastic smaller than 5 millimeters D．plastic smaller than 5 centimeters
32．Most of microplastics in air fall off ________.
A．plastic objects B．the water C．sea animals D．our body
33．Which is the correct order of the following events
① Wastewater flows into rivers and seas.
② People eat animals in the sea.
③ People wash clothes with plastic fibers.
④ Microplastics are eaten by sea animals.
A．③①④② B．①③②④ C．③①②④ D．③②①④
34．The writer wrote the passage mainly to tell us ________.
A．not to travel to the Arctic
B．not to eat animals
C．to use fewer plastic objects
D．to wear a mask(口罩) when going out
35．Where can the passage probably be taken from
A．A story book. B．A doctor's dairy.
C．An environmental newspaper. D．A clothes magazine.
Going green seems to be a fashion for a lot of people these days. Whether that is good or bad, we can’t really say, but for the two of us, going green is not a fashion but a lifestyle.
On April 22nd, 2011, we decided to go green every single day for the whole year. This meant doing 365 different green things, and it also meant challenging ourselves to go green beyond easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task.
With the idea of going green every single day for a year. Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little bit helps.
Over the course of our Green Year, we completely changed our lifestyle. We now shop at organic（有机的） stores. We eat less meat, choosing green food. We have greatly reduced our buying what we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made flesh bread. In our home office anyone caught doing something ungreen might be punished.
Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet.
36．What might be the best title for the passage
A．Going Green B．Protecting the Planet
C．Keeping Open-Minded D．Celebrating Our Green Year

We have only one earth and it’s our home, so it’s our duty to take care of it. If we harm it, we will have a terrible end. As teenagers, we should play an active role in improving the environment. If we know what to do in our daily life, we can make a difference.
