The unique ocean animals were discovered by a team of scientists led by Dr. Christine Dudgeon from Australia’s University of Queensland during a 12 year global conservation study.

The newly-found sharks have evolved (进化) to survive in low oxygen environments, enabling them to hunt during low tides. The researchers believe their ability to use their fins (鰭) to walk affords the sharks a remarkable edge over the smaller animals they try to hunt. “While they are super hunters in their shallow habitat, the tiny sharks present no threat to people,” says Dudgeon. “At less than a meter long on average, they’re incredibly cute little animals that do not look like sharks at all,” she adds.

A DNA analysis of skin samples from the live fish suggests that walking sharks broke away from their original population and became a distinct species about nine million years ago. Though that may appear to be a long time ago, it is relatively recent given that sharks have been around for more than 400 million years. In fact, Dudgeon and her team believe walking sharks are the youngest kind of sharks on Earth!

The researchers say that the sharks’ small numbers and small habitat make them extremely vulnerable (易受伤害) to natural disasters and overfishing. They are currently on the Nature Red List, which lists species at risk. Dudgeon and her team believe sensible conservation management plans are urgently needed to protect the walking sharks and other endangered animals from further threats.

1.What is the most noticeable feature of the newly-found sharks?

A.They are cute and harmless to humans.

B.They can survive in their shallow habitat.

C.They walk on their fins across the seafloor.

D.They are the youngest kind of sharks on Earth.

2.What is Paragraph 3 mainly about?

A.The evolution of the shark.

B.The behavior of the sharks.

C.The population of the sharks.

D.The DNA samples of the sharks.

3.What should be done without delay according to Dudgeon and her team?

A.Adjusting the methods of fishing.

B.Putting the sharks on the Nature Red List.

C.Changing the sharks’ living environments.

D.Adopting necessary measures to protect the sharks.

4.In which column of a website can we read the text?

A.Environment. B.Nature.

C.Education. D.Geography.

高三英语单项填空中等难度题查看答案及解析

Many of us have wondered what Earth is like beneath the surface. So have writers and scientists. In French novelist Jules Verne’s masterpiece Journey to the Center of the Earth, explorers go down to Earth’s center and discover amazing wonders.

But in real life, human beings haven’t even come close to the planet’s core (核心). The core is over 6,000 km down. The deepest hole ever created, according to the BBC, is the Kola Superdeep Borehole in Russia, which only goes 12.3 km down.

So how do we know about everything down below without any samples？

One good way to start is to think about the Earth’s density (密度), Simon Redfern of the University of Cambridge in the UK told the BBC.

“The density of the material on Earth’s surface is much lower than the average density of the whole Earth, so that tells us there’s something that has greater density,” Redfern said.

The challenge is to find out which heavy materials the core is made of. And the main material scientists have found is iron. The idea is that when Earth formed 4.5 billion years ago, a lot of iron made its way down to the core, taking up about 80 percent of it. Today scientists are still working on finding out which other materials the core could be made up of.

You might also wonder how we know the size of the core. There’s a one-word answer: seismology (地震学).

When an earthquake happens, seismic stations around the world record the shockwaves it sends throughout the planet. It’s like hitting one side of the planet with a huge hammer and listening on the other side for the noise.

Early research found that some shockwaves, called “S-waves”, went missing. S-waves can only travel through solid material, but not through liquid, so they must have found something molten in Earth’s center. By following the S-waves’ paths, scientists found out that rocks became liquid around 3,000 km down.

There are still many questions about the Earth’s core to answer. But the study of the dark world below isn’t just for scientists’ curiosity.

The movement of Earth’s molten iron core builds up a powerful magnetic (有磁力的) field. It protects us from radiation from the sun and is needed for compasses and GPS systems to work.

So perhaps none of us will ever set eyes on the core, but it’s good to know it’s there.

1.The author mentions Jules Verne’s novel Journey to the Center of the Earth in the first paragraph to　　　　　　　　 .

A. discuss the possibility of going down to Earth’s center

B. show how much humans have discovered about Earth

C. paint a picture in our imagination of the dark world below

D. show humans’ deep interest in Earth’s center

2.We can learn from the article that “S-waves”　　　　　　　　　　　　 .

A. are often used to predict earthquakes

B. cannot travel through liquid material

C. are the most noticeable shockwaves produced by earthquakes

D. can travel most rapidly at 3,000 kilometers below Earth’s surface

3.We can infer from the last three paragraphs that 　　　　　　　　　　　 .

A. research into Earth’s core has hardly made any progress in recent years

B. improvements in GPS systems could help people find out more about Earth

C. Earth’s core helps to protect humans from harm

D. scientists are likely to reach Earth’s center within dozens of years

Choose the yum(美味的东西) and risk the yuk（讨厌的东西）?

Scientists have given us a lot of health warnings. The advice from cancer experts for avoiding bowel(肠) cancer is "try to avoid processed(加工过的) meats such as bacon, ham, corned beef and some sausages", and women fearing breast cancer are told "there doesn't seem to be a starting point at which alcohol consumption is safe",

But all these health warnings tend to have little influence on behavior, So who is being unreasonable —the scientists who give us health advice, or the public that just ignores it?

The curious fact is that both might be right. The reasoning behind these health warnings seems to be this: if you do more of something pleasurable (which we shall give the name “yum”) there is a higher risk of something bad (which we shall give the name “yuk”)occurring, so you should avoid yum.

But when presented with this argument you might ask two questions.

First, maybe the pleasure of yum makes the risk worth taking, especially if yuk might occur a long time in the future? Second, maybe there are other benefits of yum that could cancel out the risks of the particular yuk that has been identified (确认) ?

So suppose bacon sandwiches are your particular yum: research shows that 50g per day — that is a great greasy sandwich — increases your risk of bowel cancer by 20%.

But this means that out of every 100 people who stuffed down that big bacon sandwich every day of their lives, the number of bowel cancers would rise from five to six.

In addition, if a middle-aged woman gave up alcohol, it might reduce her risk of breast cancer, but could increase risk of some other cancers as well as heart disease.

So we need to look at the whole picture before trying to get people to change what they do, since everything has benefit and harms — just think of the joggers(慢跑者) who get knocked down by cars — and people need to be able to find their own balance.

Therefore, as you reach for your yum, perhaps sometimes pause a moment and realize that you are taking a gamble(赌博) on the yuk occurring, but that it may be a risk worth taking.

1.What is the advice given by scientists for avoiding breast cancer?

A. Try to avoid processed meat. B. Try to avoid alcohol.

C. Try to choose the yum.           D. Try to risk the yuk.

2. What does “this argument” in Paragraph 4 mean?

A. If you choose the yum, you will risk the yuk.

B. If you risk the yuk, you’ll choose the yum.

C. The yum is worth taking, especially if yuk might occur in the future.

D. Other benefits of yum could cancel out the risks of the yuk.

3.Why do we need to look at the whole picture before trying to get people to change what they do?

A. Because giving up alcohol might reduce breast cancer.

B. Because people are not able to find their own balance.

C. Because all the things have both sides.

D. Because the advice given by scientists is not true.

4.According to the passage, which of the following is correct?

A. People are often influenced by the health warnings.

B. Both the scientists and the public are not reasonable.

C. Alcohol consumption has both benefit and harms.

D. People should avoid yum to reduce the risk of yuk.
