One million species face extinction, more than ever before in human history, according to a UN report released in May. And humans should be responsible.

The Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) based the assessment (评估) on some 15,000 sources considering the causes and results of environmental changes over the past 50 years.

The findings are clear and alarming. The researchers have found that about 25 percent of the world’s plants and animals are at risk of extinction. These include sea and land animals. Even the domesticated (驯养的) animals are at risk: Over 9 percent of the domesticated animal species used for food and agriculture might have been lost.

There are some big problems. This rapid decrease of the natural world endangers global food safety and quality of life. For example, about 4 billion people rely on natural medicines, produced by the disappearing species, for their health care. And losses of species that pollinate (授粉) plants threaten up to $ 577 billion in crops each year.

The researchers identified five drivers responsible for the unpleasant news. They think at the top of the list is the change of land and sea use. The change in ecosystems towards agriculture, aquaculture and other human developments has led to changes in the natural living space of species. It is followed by the direct overuse of creatures (harvesting crops, cutting down the trees, hunting and fishing) and climate change, including rising sea levels and increasing extreme-weather events, wildfires, floods and droughts. The final causes of species extinction are pollution, especially plastics, and the spread of non-native species that can displace or kill native plants and animals.

The researchers say it is time for humans to make a change. They think maybe a new global way to save food and refuse waste in our everyday life could turn the tables. Whether that is possible is an open question.

1. What is the main purpose of the first paragraph?
A.To introduce the topic of the text.
B.To introduce the schedule of the report.
C.To introduce humans’ sense of responsibility.
D.To introduce the history of human development.
2. What does paragraph 3 mainly show?
A.The reliability of the findings.
B.The species of animals worldwide.
C.The seriousness of species’ reduction.
D.The risky experiences of the researchers.
3. What is the biggest threat to species’ survival according to the researchers?
A.Climate change.
B.Natural disasters.
C.Changes of their living space.
D.The direct overuse of creatures.
4. What are the researchers in favor of?
A.Ignoring the food problem.
B.Spreading non-native species.
C.Limiting native plants and animals.
D.Changing some habits in our daily life.

文章大意:本篇是记叙文。讲述一个小女孩成功说服父母,得偿所愿抚养了一只小猫的故事。

【推荐1】My wife isn’t a cat person. So when our daughter Flora started asking for a cat several years ago, my wife politely refused her requests and we didn’t give it a second thought. Flora, though, shares some of my wife’s persistence, so she continued to ask for a cat repeatedly for several years.

Then a couple of things happened that made us take a closer look at things. When we went to Flora’s parent-teacher conferences, the teacher first handed us an essay about how my daughter wanted a cat, and then an imaginary story about where she would like to go on vacation: Catville.

It was then that my wife and I came to the realization that our daughter wasn’t just messing around here. And it was time for us to break down. But before we brought our new cat home, my wife sternly warned us that she was not going to be the one to take care of or clean up after the cat. Flora was going to take full responsibility. Fine, my daughter said.

We welcomed our mini family member into the house right around Christmas. We named her Goldy. When we got her, she peed everywhere. But other than that, she was perfect. My tough-talking wife gradually fell in love with Goldy. And Goldy fell in love with her. Of course, it’s not just my wife who loves Goldy. We all do.

There are so many things about that cat that absolutely brighten our life, highlighted by how she nearly bursts with affection when we come home or wake up in the morning. From the moment Goldy came into our house, it seemed unreasonable that we didn’t have a cat before then. We should have settled down to the decision much earlier.

1. What led the family to rethink about the idea of keeping a cat?
A.The author’s promise.B.The teacher’s advice
C.The wife’s expectation.D.The daughter’s effort.
2. What does the underlined word “sternly” mean in Paragraph 3?
A.Seriously.B.Defensively.C.Anxiously.D.Mildly.
3. What kind of person is the author’s wife?
A.Inspiring and patient.B.Principled and kindhearted.
C.Ethical and traditional.D.Positive and professional.
4. What can be a suitable title for the text?
A.A Healing CatB.My Determined daughter
C.Best Decision EverD.Family Means Everything

【推荐2】Dear Graham,

My partner and I have recently lost a pet quite suddenly. Normal life is continuing with so much sadness for my pet meant so much to me. Lots of people won't understand my feeling this way about the death of an animal. This obviously isn't the first time someone in my life has passed away: when I was younger we lost elderly relatives who I loved very much, and naturally much-loved family pets died occasionally too. But this has hit me so much harder. I put so much love into the relationship and I'm just finding it hard to get my head around the fact that it's gone.

Thank you for taking the time to read this.

ANON, VIA EMAIL


Dear Anon,

Something you loved deeply has gone from your life, so of course you are sad. We love our pets differently from family members or friends and part of that is because we know they will probably die before us. Our time with our dogs or cats is precious precisely because we understand it is limited.

As humans, we go through most of life understanding we would die one day. But animals don’t. We are the keeper of the secret. Of course, living a life unencumbered(不受妨碍) by thoughts of death means that our pets, in general, lead very simple, happy lives. It’s one of the reasons why they are such a joy to be round. You are, of course, correct when you say that many people don't understand your grief, so don't talk to them. Share your feelings with like-minded souls. I'm sure a simple search online will reveal many practical advice for moving on.

And when you are ready, you can welcome another animal into your life and then you will enjoy happiness again.

GRAHAM, VIA EMAIL

文章大意:本文是一篇说明文。由于栖息地被破坏,西达莫歌百灵可能很快成为自现代记录开始以来非洲大陆上第一个灭绝的鸟类。为此,环保主义者提出了相应的解决办法。

【推荐3】The Sidamo lark(西达莫歌百灵), discovered by scientists in 1968, is known only from a small area of southern Ethiopia. The bird is one of the most ancient types of larks known anywhere.

The Sidamo lark has brown feathers. Male and female Sidamo larks look alike. It calls with a series of quick and short sounds, typically heard as it flies high into the sky. The Sidamo lark has very special habitat requirements, having only been found in grassland with a few bushes. For thousands of years, both the wild animals and humans kept the grassland in good condition. This habitat is now being destroyed. Wild animals are too few to stop bushes growing, while growing agriculture is damaging the grassland. The Sidamo lark is thought to have a very small population now.

Sidamo lark could soon be the first bird in mainland Africa to die out since modern records began. Research has found that just a few hundred of the larks survive in Ethiopia. Unless action is taken to save it, the bird will disappear. It will be the first recorded bird dying out on the continent.

To save the bird from extinction, environmentalists have suggested the creation of small fields in which cattle could eat grass. This would stop damage to the grassland and protect the grass cover. Bushes should also be removed, while a limit should be placed on crops coming further into the bird’s habitat.

1. What kind of habitat does the Sidamo lark need?
A.Grassland with thick bushes.
B.Grassland with many wild animals.
C.Grassland covered with bushes here and there.
D.Grassland with a few bushes.
2. What do we know about the Sidamo lark’s habitat now?
A.It is under good protection now.
B.It has been replaced by small fields in which cattle eat grass.
C.It is being damaged by agriculture.
D.It has been removed to some other places.
3. What can we infer from the passage?
A.Thick bushes are harmful to the survival of Sidamo larks.
B.Africa has the most kinds of larks in the world.
C.Larks only exist in the African mainland.
D.Larks are found where there is grassland.
4. Which would be the best title for the passage?
A.The Sidamo lark, a beautiful bird in Africa
B.The Sidamo lark soon to be extinct
C.The ways to protect the Sidamo lark
D.The Sidamo lark and its habitat
