主题：海鸟误食塑料垃圾
(2022·广西贵港·统考三模改编)
短文导读：本文介绍了海洋中的塑料污染问题，呼吁人们重视这一问题，保护海鸟免受伤害。
语法选择A
A. 回答问题
请阅读下面短文，根据所提供的信息，回答5个问题。要求所写答案语法正确、语义完整切题，并把答案写在横线上。
Birds don't like eating plastic. But more seabirds are eating plastic waste in the world's oceans. Why
It is possible because the plastic waste smells like food, according to a new study published in the magazine Science Advances.
Matthew Savoca is the study's lead writer at University of California. “Animals usually have a reason for the decisions they make,” he said. “If we want to truly understand why animals are eating plastic in the ocean, we have to think about how animals find food.”
The study found that plastic waste easily collects algae (海藻) on the water. Together, they give off a smell that is very similar to the krill (磷虾). Many seabirds feed on the krill. It could explain why some birds—including albatrosses (信天翁) and shearwaters (剪水鹱)—are nearly six times more likely to eat plastic than other birds. They usually find food by their sense of smell.
More plastic pollution enters the world's oceans every year. A study last year showed that about 8 million tons of plastic enter the oceans every year. It is enough to cover every coastline (海岸线) in the world. Birds and other sea animals, such as fish, eat plastic. It can badly hurt their organs (器官). Some birds even feed their babies waste instead of food by mistake.
Scientists hope this study can wake people up and help save the seabirds.

Did you know that most of the energy we use comes from the sun For example, the sun helps plants to grow. Plants then turned into coal, oil and natural gas. We call these fossil fuels (化石燃料).
However, fossil fuels make pollution. This is bad for the earth. They are also non-renewable. Some day they will be gone. So scientists want people to use green energy. Why is green energy important First, it is clean. It doesn't hurt the earth. Next, it is renewable. It won't run out. Green energy gives us almost 25% of the electricity we use today.
Water Power
Water power uses moving water in rivers. Moving water has energy. Water power makes 16.6% of the electricity we use.
What are the main sources (来源) of green energy
Wind Power
People used wind power many years ago. Wind power makes 4% of the electricity we use.
Solar Power
Soar power comes from sunlight. The sun shines on solar panels (太阳能板) and electricity is made. Solar power is now as cheap as some fossil fuels. It makes 15% of the electricity we use.
Biomass (生物质能)
Biomass is energy that we get from plants around us. For example, deadwood or grass is burned to make electricity. It is green energy because we can plant new trees or crops. Biomass makes 2% of the electricity we use.
New Green Energy
The moving water of the ocean can make electricity. We call it tide power. There is also heat under the earth's surface. We use this heat for energy and it's called heat power.

主题：纪录片《地球改变之年》
(2022·内蒙古鄂尔多斯·中考改编)
短文导读：本文用纪录片《地球改变之年》告诉我们疫情之下世界的变化，即使是很小的改变，也会对地球产生很大的影响。
阅读理解B
Recent three years has been really challenging for people both home and abroad. Our lifestyle has changed because of COVID-19. We have to stay at home more often to keep healthy, leaving more space for animals.
In celebration of Earth Day, a new documentary (纪录片) The Year Earth Changed came out. It shows how different the world looks like after a year of worldwide human quarantine (隔离).
“During this difficult year, lots of people have realized the value and beauty of the natural world,” said the narrator of the documentary. “Now we can see clearly the relationship between humans and animals.”
While humans spent most of their time at home, there was less noise, less pollution, more food and more space for animals. In the ocean, without ships nearby, whales and other animals were able to communicate easily. Whale parents could travel farther to feed, because they know their young could hear them from far. They made sounds that scientists had never heard before. On the land, people saw penguins walking in the street, deer passing by stores and monkeys playing in the park. In the sky, children noticed more and more birds singing and dancing freely.
The documentary reminds us of one thing: Making even a small change to what we do can make a big difference. As we stop, amazing things start to happen in the natural world. These changes are recorded in this documentary as well as in our memory.
In the future, humans will develop and life will continue. The difference is that now we know how beautiful nature can be and we can choose to keep this beauty with us in life.

主题：学生发明AI智能垃圾桶
(2022·海南·中考改编)
短文导读：本文介绍了一项新的发明——智能垃圾箱。
时事热点主题阅读理解
①Do you ever stand in front of rubbish bins and wonder whether the waste in your hand is recyclable(可循环再用的) or not To solve this problem, four Hong Kong high school students have invented a smart rubbish bin. It uses AI to sort the waste. The students named the bin Waste Collection Point.
②Connected to a computer, the bin uses a camera to tell the kind of the waste it receives. It can sort the rubbish into plastic, paper, glass or other kinds. To make sure it works correctly, the team tested every product in the school shop and took at least 500 pictures of each one. “To train the AI, we had to take many photos from different angles(角度), so it has a better rate of accuracy(精准度),” said one of the students.
③The idea of the smart bin was born two years ago. At that time, people from the city crowded into their village because of the COVID-19. They left behind a lot of rubbish and caused more pollution.
④“All the bins were full and there was even rubbish on the mountain,” the students recalled.“Every weekend, we had to join the villagers in picking up the waste.”
⑤The students decided to develop a special recycling bin that would encourage people to protect the environment. Although school ended at 2 p. m. , the team would continue to work on their invention until 6 or 7 p. m. at school. Even when their school was closed last year, they would still meet and work together online.
⑥“Our bin is now in its third generation. Before graduation, we hope it can be widely used in the city,” The students said. “Then it will be easier than ever for people to recycle and protect our environment.”
