The Albatross(信天翁) A What is an Albatross?
Albatrosses are the largest seabirds in existence,with wingspans(翼幅)which extend to over three metres in width.They represent a small subset of the larger group known as tube-nosed petrels,which have strong,curved sharp beaks which they use for catching fish and squid on the surface of the ocean.While there is some debate about the exact taxonomy of the species,it is agreed that there are somewhere between 21 and 24 species of albatrosses.
B A Special Breeding Site
Of these species,approximately half breed in New Zealand and about 80 percent breed(繁殖)or fish within New Zealand's territorial waters.Six species breed only in New Zealand or on its offshore islands.One of only two mainland nesting sites for these birds in the world,for the northern royal albatross,is on the Otago Peninsula in the South Island of New Zealand;it is a popular tourist destination.Visitors can view the albatross colony(種群)from a special building which has been established beside the nesting ground and,while the site is closed during breeding season(繁殖季),at other times it is often possible to see parents and their chicks living and feeding only metres away from human observers.
C Predators
However,there are risks to albatross chicks(幼鳥)on land.Natural predators(捕食者)such as seagulls can eat eggs and young birds,and in mainland areas there are also threats from dogs,cats and other land animals.On some offshore islands,sea lions have been observed raiding(襲擊)nests for eggs.It is thought that this is a new behaviour.
D Threats (危險(xiǎn))for Adult Albatross
The main threats to the adult albatross occur at sea,and most of these are man-made.Albatrosses like to travel close to fishing boats,to eat the leftover scraps of fish that are dropped over the side of the boat.Sometimes,however,they also eat the bait(餌)and accidentally ingest(咽下)fish hooks(鉤),or get dragged(拖,拉) along on fishing lines and drown.The number of albatrosses that any one boat catches is small,but because there are so many fishing boats,this may have a long term impact on population numbers.It is estimated(預(yù)估)that at least 100,000 albatrosses die in this way each year.As for all sea bird species,there are other threats,such as drift nets,oil spills and rubbish such as plastic in the ocean.While there are international agreements and fishing conventions to try and protect sea birds,albatrosses are among the million or so sea birds that get caught in drift nets and die each year.

1.It is widely believed that biodiversity(生物多樣性)is promoted to save species.But in reality species exist only as part of ecosystems and cannot survive unless their ecosystems are protected along with as much as possible of the diversity they contain.
Protecting habitats(棲息地)is important for keeping biodiversity.In 2003,over 102,000 habitats covering nearly 19 million square kilometres,or 11.5% of the world's land surface,were under some form of protection.Though this is a great improvement since 1962,when just 1,000 protected habitats were listed,it is still not considered enough to stop the ecocide that is endangering the world's biodiversity.
For a number of environmentalist,protecting the world's 25 biodiversity hotspots(熱點(diǎn)地區(qū))is critical to saving habitats and species.But many hotspots are endangered already,having lost up to three-quarters of their original plants.
The poor state of most biodiversity hotspots results directly from population growth and migration(遷移) into these areas.A study found that by the mid-1990s around 1.1 billion people lived in these hotspots.Moreover,the annual population growth rate in these areas was 1.8%,higher than the global average of 1.4%.The PAI report concluded that human-related environmental changes will continue to put pressure on hotspots.Therefore,keeping biodiversity requires paying close attention to population size.
Protecting hotspots is not simply a matter of putting up fences and employing guards.The best results are achieved when local people are educated about the value of wildlife,and actually gain a share of the benefits from eco-tourism.Only then do they have a chance to see the benefits of protecting hotpots.
(1)What can we infer from paragraph 1?
A.The loss of any species can affect humans.
B.Endangered species are paid more attention to by humans.
C.Species can still survive when their ecosystems are destroyed.
D.Ecosystem protection is as important as diversity protection.
(2)What does the underlined word "ecocide" in paragraph 2 mean?
A.Ecosystem protection.
B.Reduction of the number of species.
C.Serious damage to habitats.
D.Habitats protection.
(3)What's the direct cause of the terrible state of the hotspots?
A.Population growth in hotpots.
B.Migration out of these areas.
C.Global warming.
D.The global average population growth rate.
(4)What's the author's opinion on protecting the hotspots?
A.It's simple to carry out.
B.It leads to the increase of tourists.
C.It's closely connected with local people.
D.It suggests that the local people are well educated.發(fā)布:2025/1/6 16:30:6組卷:0引用:1難度:0.5 -
2.International students who stayed in the US as their classes moved online during the COVID may be forced to leave,following guidelines of the US Immigration and Customs Enforcement published due to the pandemic(流行?。?
"You know I don't want to put my family at risk,I don't want to put myself at risk to travel during a pandemic and go back to Pakistan,and even if I could delay the program for a year,it is not certain that I will get the visa again." said a Pakistani student.
Many students say they need to be in the US for more than attending cljye.ais.As a PhD student,the library is an extremely important resource for them,although it is because of COVED that those services have been closed,which means even this advantage is gone.
"You know more than 90% of the international students who were studying the US when COVID-19 hit and college campuses were closed have to remain in the US and this creates such trouble in their lives and such uncertainty that is unreasonable." said a lady from a university.
International students staving in the United States say the new ruling has disturbed their plans to return. "I know it is a fact that when it comes to rules,guidelines,laws and stuff like that,international students are sort of treated as low-level citizens.Even I can't even use the word "citizen" to begin with because that's what they make clear we are not."
The government said that the policy speaks for itself and that online coursework is not worth a visa.So far,not any sign of change has been within sight.As students are waiting for the policy to improve,their fall programming and their future remain in limbo.
(1)Why would international students prefer to stay in the US during the pandemic?
A.They couldn't delay the program for a year.
B.They can make full use of the library resource.
C.They wouldn't bring any potential danger to their family.
D.They can learn better with their classes moved online.
(2)What do international students staying in the United States think of the new rule?
A.The new rule treats them as American citizens.
B.The new rule shows great unreasonable opinion against them.
C.The new rule guides them to plan to return to the US.
D.The new rule treats them like low-level students in school.
(3)What is the government's attitude towards the new rule?
A.Favorable.
B.Neutral(中立).
C.Unfavorable.
D.Unclear.
(4)What does the underlined phrase "in limbo" in the last paragraph mean?
A.Horrible.
B.Flexible.
C.Uncertain.
D.Unbelievable.發(fā)布:2025/1/6 15:30:8組卷:0引用:1難度:0.5 -
3.Most of us spend our lives seeking the natural world.We go fishing,sit in the garden,have a picnic,live in the suburbs or go to the seaside.The most popular leisure activity in Britain is going for a walk.When joggers jog,they don't run on the streets.Every one of them tends to go to the park or the river.
But despite this,our children are growing up naturedeprived(剝奪).I spent my boyhood climbing trees.These days,children are robbed of the ancient freedom,due to problems like crime,traffic,the loss of the open space and strange new ideas about what is best for children,that is to say,things that can be bought,rather than things that can be found.
The truth is to be found elsewhere.A study in the US:families had moved to better housing and the children were assessed for ADHD—Attention Deficit Hyperactivity Disorder(注意力缺陷多動(dòng)癥).Those whose accommodation had more natural views showed an improvement of 19%;those who had the same improvement in material surroundings but no nice view improved just 4%.
ADHD is one of the great problems of modern childhood.One study after another indicates that contact with nature gives huge benefits to ADHD children.However,we spend money on drugs rather than on green places.
The life of old people is measurably better when they have access to nature.The increasing concern for the growing population of old people is in quality rather than quantity of years.And study after study finds that a garden is the single most important thing in finding that quality.Even problems with crime and aggressive behaviour are reduced when there is contact with the natural world.
We need the wild world.It is essential to our wellbeing,our health and our happiness.
(1)According to the author,people enjoy
A.jogging on the street
B.running in the gym
C.shopping in the supermarket
D.sitting in the garden
(2)From the second paragraph,we can see that
A.Children don't want to approach nature
B.children probably spend less time in nature nowadays
C.climbing trees will certainly do good to the children
D.children tend to be happier as a result of their material satisfaction
(3)In what way do people benefit from their contact with nature?
A.Children with ADHD can be cured.
B.Children's performance at school is greatly improved.
C.Problems with crime and violent behavior will easily be solved.
D.A garden nearby improves the quality of old people's life.
(4)what is the main idea of this passage?
A.Access to nature improves our life.
B.Nature treats children for ADHD.
C.Getting close to nature reduces crime.
D.Man can't live without natural areas.發(fā)布:2025/1/6 16:30:6組卷:0引用:1難度:0.5
