Cats’ sense of smell is very important to their health. Many cat owners have seen a cat smell the food and refuses it. Careful sniffing( 嗅) tells the cat if something is safe to eat.
Cats have a pair of vomeronasal organs(犁鼻器) on the roof of the mouth. When the cat wants to sniff， she will breathe the air in through her mouth. At this moment， she will often squint(斜视) her eyes and maybe even flatten(使…平坦) her ears. This makes her look like she is making faces. The vomeronasal organs will then analyze(分析)the smell---almost as if the cat is tasting the smell.
When you come home from outside the house， your cat can smell what you had for lunch and for a mid-afternoon snack. She can smell the people you shook hands with and your neighbour you stopped to talk to and hug. She can smell the grass brought under your shoes as you took a shortcut across the lawn. Your cat’s sense of smell is so good that she can smell difference between a gallon of water with a teaspoon of salt in it and plain water. In comparison， we think of salt as completely tasteless.
Cats have scent glands(臭腺) on each side of the forehead， on the chin， the lips and next to the tail. When your cat rubs up against your hand， your leg， the sofa， and your bed， she is leaving her scent in those things. She will then use her sense of smell to recognize “her” things， people and even other pets in the home.
If you want to have fun with your cat’s sense of smell， take some small bits of different things， such as a bit of chicken， some flowers and some fish. Place each different scent under a piece of paper towel(so your cat cannot see any of them) and encourage your cat to investigate and find what kind of food she likes to eat best.

Steve is James and John’s big brother. One day, when their mum left for work, James and John started crying. They didn’t want her to leave. Steve tried to stop them crying and said, “Let’s play hide-and-seek (捉迷藏). You hide and I’ll count to ten. Then I’ll try to find you.” Steve found James under a chair and John behind a door. They played over and over again. Each time, the two boys hid in the same places. Finally, Steve felt too bored with the game. “Let’s take the dog for a walk,” he said.
When Steve walked the dog, he found James and John were running in the street. He thought it was so dangerous. Then he had an idea. “Anyone who walks back to the house with me can have some snacks!” Steve shouted.
At home, the boys ate some cookies and got ready for a sleep. James and John wanted a story. Steve told them the story about the little red hen. When their mum returned home, she was pleased to find the three sleeping boys.

Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can’t talk, but can they lie with their bodies and behavior? Animal experts may not call it lying, but they do agree that many animals behave dishonestly to fool other animals. Dishonesty often helps them survive（生存）.
Many kinds of birds are very successful at fooling other animals. A bird called the plover sometimes pretends （假装） to be hurt in order to protect its young. When an enemy gets close to its nest, the plover pretends to have a broken wing. The enemy follows the “hurt” adult, leaving the baby birds safe.
Another kind of bird, the scrub jay, buries （埋） its food so it always has something to eat. Scrub jays also steal food. They watch where others bury their food and steal it. But clever scrub jays seem to know when others are watching them. So they get back later, unbury the food, and bury it again somewhere else.
Chimpanzees can also be sneaky. After a fight, the losing chimpanzee will give its hand to the other. When the winning chimpanzee puts out its hand, too, the chimpanzees are friendly again. But an animal expert once saw a losing chimpanzee take the winner’s hand and start fighting again. When chimpanzees find food, it’s natural for them to cry out. Then other chimpanzees come running. But some clever chimpanzees learn to cry very softly when they find food. That way, other chimpanzees don’t hear them, and they don’t need to share the food.
(1). Why does the plover pretend to be hurt?
| A． | To show its friendliness. |

| A． | It will eat all the food it finds. |
| B． | It will share the food with others. |
| C． | It will fight again with the winner. |

|

|

More than 1,000 schools across the UK have signed up（报名）to a project with the aim of helping schools become carbon neutral（碳平衡的）by 2030. Carbon neutral means cutting down carbon emissions（碳排放）to zero or balancing them out in other ways. Carbon emissions are gases such as carbon dioxide（CO2）that come out into the atmosphere, where they make climate change worse. This has also caused the temperature rise.
Emissions are caused by all sorts of human activities, such as burning fossil fuels（coal, oil and gas）to make energy, cutting down forests and some types of farming. Becoming carbon neutral includes cutting the amount of carbon emissions a school produces and balancing those that are left by taking some carbon out of the atmosphere.
The project also shows how small changes can make a big difference. These might include thinking carefully about energy use, cutting waste, growing food closer to where it's eaten and walking or cycling to school if it is possible. Ways of balancing out the carbon emissions that a school still makes include planting trees and plants that take in CO2 as they grow.
Ysgol Bro Dinefwr Secondary School in Wales has promised to run entirely on renewable（可再生的）energy（such as wind and solar power）within the next three years. At Down High School in Northern Ireland, the students are looking after their own bees. So when flowers and crops produce food, that helps. Other schools have projects to cut food waste by weighing it after each meal to know how much is not being eaten. Some put the waste into a system that can turn this waste into useful things. They will be put on the garden to help plants grow.
Climate change is seen as a major global challenge. We can see it all around us. So join together, find out ways your school can put efforts to, and talk to a teacher about signing up.

| A． | Human activities influence the environment. |
| B． | The fight against climate change will not succeed. |

(2). How could the schools reduce carbon emissions?
| A． | By moving to the countryside. |
B． | By cutting waste and planting trees. |
| C． | By providing more spaces for students. |
D． | By burning coal instead of gas to make energy. |
(3). Why does the author give examples of the schools in paragraph 4?

When we think of the most respected awards in the world, the Nobel Prize（诺贝尔奖）must be on the list.
Created by Swedish inventor Alfred Nobel in 1895, the prize recognizes achievements in sciences and the people behind them. Every year in October, the announcement of winners catches the world’s attention.
But what is the importance behind this award? According to founder Nobel himself, the prize is for people who have provided “the greatest benefit to humankind”.
A number of Nobel Prizes have rewarded discoveries that have led to cures for diseases and health problems. A lot of parts in telephones, computers and telecommunication systems are also the fruits of Nobel Prize—awarded work. Other prizes have recognized those who have helped to create a more peaceful world.
The individuals selected and the contributions they made show how science, literature and peace efforts improve and change the world and better our lives.
In the series of books about the Nobel Prize, the author says, “many everyday things would be impossible without the work of the winners of the Nobel science prizes”.
Think about the plastic bags. Plastic wouldn’t have been invented without Friedrich Wilhelm Ostwald’s research. The German scientist won the Nobel Prize in 1909.
In recent years, Chinese people have paid more attention to the results of the Nobel Prize. Chinese scientists and writers are known to the world by their achievements, such as 2012 Nobel literature prize winner Mo Yan, and Tu Youyou, China’s first Nobel winner in physiology or medicine in 2015. It’s an uplifting thing. Not only for the individual achievements, but also for the national confidence.
The Paper noted that the prize can encourage the young generation to do scientific research. Do you have any ideas about this?
