Frogs are animals that can live both in water and on land. There are more than 5,000 kinds of frogs on the earth. The earliest known frogs lived about 190 million years ago and the frogs today still look the same. Here are some fun things that you might not know about frogs. Enjoy!
The Biggest and the Smallest Frogs
Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be nearly 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest frogs in the world. They are less than 1cm long. Though the Poison Frog is very small, it is not weak at all. It is dangerous. Any animal that eats it will die very soon.
The Best Jumpers
Frogs are very good at jumping. They developed jumping legs so that they would not be eaten by other large animals. Using their big strong legs, more frogs can jump over 20 times their own length. It is like a person jumping over about 30,48. The Australian Rocket Frog can even jump over 2m, which is 50 times its body length(5.5cm). That might be the reason why frogs are called the best jumpers on the earth.
The Cryogenic Animal
Some frogs like the Common Wood Frog have a special ability to live in very cold places. When the temperature goes down, they become ice frogs. 2/3of their body water freezes. Their hearts stop, and their breathing stops too. You may think they are dead, but in fact they are not. Maybe we humans can learn the way that the frogs do for medical purpose.

Dogs can know the meaning of a human perspective, say researchers.
Dogs are more capable of understanding situations from a human's point of view than has previously been recognized, according to researchers.
They found dogs were four times more likely to steal food they had been forbidden, when lights were turned off so humans in the room could not see.
This suggested the dogs were able to alter their behavior when they knew their owners' perspective had changed.
The study, published in Animal Cognition, conducted tests on eighty-four dogs.
The experiments had been trying to find whether dogs could make their behavior suitable to react to the changed circumstances of their human owners. It wanted to see if dogs had a "flexible understanding" that could show they understood the viewpoint of a human.
It found that when the lights were turned off, dogs in a room with their human owners were much more likely to disobey and steal forbidden food.
The study says it is "unlikely that the dogs simply forgot that the human was in the room" when there was no light. Instead it seems as though the dogs were able to differentiate between when the human was unable or able to see them.
Juliane Kaminski carried out the research into how dogs are influenced by human circumstances.
Dr Juliane Kaminski, from the University of Portsmouth's psychology department, said the study was "incredible because it implies dogs understand the human can't see them, meaning they might understand the human perspective".
Previous studies have suggested that although humans might think that they can recognize different expressions on their dogs' faces, this is often inaccurate and a projection of human emotions.
“Humans constantly attribute(歸屬) certain qualities and emotions to other living things. We know that our own dog is clever or sensitive, but that's us thinking, not them,” said Dr Kaminski.
“These results suggest humans might be right, where dogs are concerned, but we still can't be completely sure if the results mean dogs have a truly flexible understanding of the mind and others' minds. It has always been assumed only humans had this ability.
小題1:According to the passage, which of the following is TRUE?

A．The researchers made the test on dogs in eighty-four countries.

B．Dogs always obey and don’t steal forbidden food.

C．Dogs may adapt their behavior in response to the changed circumstances.

D．The research is carried out to find out how dogs are influenced by light.

小題2:Which of the following can best serve as the title of the passage?

A．Dogs---Our Loyal Companions Understand Us Most.

B．Dogs Are Our Best Friends.

C．Dogs Can Understand Us In a Way, Researchers Say.

D．Dogs Have Certain Qualities and Emotions of Human Beings, Researchers Say.

小題3:Where can we probably read this kind of articles?

A．Textbooks.

B．Advertisements.

C．Instructions.

D．Magazines.

小題4:This passage can be classified as .

A．an argumentative writing	B．a feature story

“A very destructive seven-year old child kicked my legs and scratched at my hand,” said one teacher. “I broke up a fight and was kicked,” said another. Many people have heard stories like this. But the situation is more worrying still and it involves parents.
Every child, regardless of the circumstances into which they are born, has the right to achieve their potential, regardless of their parents’ wealth and class. And we recognize that, as a nation, it is a long way to achieve this goal. But rights come with responsibilities and what worries people is that we are in danger of neglecting the latter.
Far too many children are behaving badly at school, even to the point of being violent to staff. This is terrible enough，but it is hard to be surprised since many children are just mirroring the behavior of their parents. Too many are starting school unable to hold a knife and fork, unused to eating at a table，and unable to use the lavatory properly.
We are in danger of becoming a nation of families living separate lives under one roof. The bedroom, once a place to sleep, has become the living space for the young. Spending hours in front of computer screens, on social networking sites or being immersed in computer games, children and young people spend little time with their parents. Parents are unable to monitor just what their children are watching.
Schools cannot right the wrongs of society and teachers cannot become substitute parents. Both parties need to work together. Parents must be helped and given confidence to take back control. They are responsible for setting boundaries for their children’s behavior and sticking to those boundaries when the going gets tough. They are responsible for setting a good example to their children and for devoting that most precious of resources---time---so that children come to school ready and willing to learn.
小題1:What problem do people ignore in the writer’s opinion?

A．The school violence

B．The pressure of students’ learning

C．The right to achieve students’ potential

D．Students’ responsibilities

小題2:The writer’s attitude to the behaviors of parents may be that of .

A．dissatisfaction

B．sympathy

C．understanding

D．tolerance

小題3:The underlined part in Paragraph 4 may mean .

A．children don’t live with their parents in the same room

B．parents care little about children’s life at home

C．children spend little time with their parents at home

D．parents attempt to establish a good relationship with their children

小題4:From the last paragraph,we can infer that .

A．school can’t correct the wrongs that society does to teachers

B．teachers have no responsibility for playing the role of parents

C．parents should spend time with children making them ready to learn

D．students are responsible for making themselves known in society

小題5:What is the main idea of the passage?

A．Children’s behavior at school is worrying people

B．Parents expect schools to correct their children’s bad habits

C．There is no point in parents’teaching children at home

D．Don’t blame teachers when it’s parents who are failing

Pupils remember more and behave better when 3D images are used in lessons, research suggests. They are quicker to learn and absorb new concepts, and display higher levels of concentration.
Professor Anne Bamford, of the University of the Arts, London, studied the effectiveness of 3D content in 15 schools across seven countries, including the UK. Pupils in 3D classes could remember more than those in the 2D classes after four weeks, improving test scores by an average 17 percent compared with eight percent for 2D lessons. They gave more detailed answers to the tasks and were more likely to think in 3D, using hand gestures and mime (模仿動作) to answer the test questions successfully.

The teachers commented that the pupils in the 3D groups had deeper understanding, increased attention span, more motivation and higher engagement in the lessons
Children are used to 3D with the rise of computer games that use the technology—90 percent of those in the study had seen a 3D film. Schools would need 3D-enabled projectors（投影儀）, laptops with good picture capabilities, 3D software and glasses for children to introduce animations (動作) into classrooms.
But Danny Nicholson, an educationist, said the technology would be impractical to use in schools and could be too expensive. He said,“While I think the idea of 3D technology is very interesting, I worry that 3D is a bit of an expensive gimmick (小玩意兒). There are a few cases where a true 3D image might help, but most of the time, good 2D models that can be moved , would be just so effective.”
In Colorado, the US, one school district is already in the process of having 1,000 3D projectors fixed in classrooms. And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils. Those who watched the 3D presentations were more engaged and reported a general increase in their interest in science compared with students who watched the 2D version.
小題1:Teachers think pupils in 3D classes .

A．are naughtier than those in 2D classes	B．have less motivation
C．find it hard to concentrate	D．have deeper understanding

小題2:Danny Nicholson tends to think that .

A．many pupils prefer 2D models

B．3D is a bit expensive for some schools

C．true 3D images would not help in classes

D．3D technology has a bright future in classes

小題3:What can we learn from the last paragraph?

A．3D classes will soon be given in one school district in Colorado.

B．Teachers will use the 3D technology through specific training.

C．Many pupils are now more interested in science than before.

D．3D technology will replace 2D models in the future.

小題4:What is the text mainly about?

A．2D models are always more effective than 3D images.

B．The differences between 3D and 2D images.

C．How schools can make full use of 3D technology.

D．Pupils behave better when 3D images are used in classes.

小題5:Where is the text most probably taken from?

A．A history book.	B．A news story
C．A science magazine.	D．A school report.

Since the beginning of the year, smog has covered parts of North China. In January, Beijing saw only five days without smog. The rising PM 2.5 readings terrified many people, and some health experts said that whenever the smog gets serious, hospitals receive more patients suffering acute respiratory（呼吸系統）and heart diseases.
Later, news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe.
So the need to emphasize environmental protection while developing the economy is heard everywhere.
Smog especially is a common concern. Like a popular online post said, air may be the only thing that is equal for everyone, despite your income or vocation. People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices, but they breathe the same air as everyone else.
At a meeting on Monday, many Representatives have expressed their concerns about the air quality, too. One talked about his experience in Beijing. “After taking a taxi from the capital airport to my hotel, which took about an hour, I washed my nose and found the inside of my nose was black. We should ask ourselves this question: Why do we want to develop? It's for living a better life. Dirty air is definitely not a better life," he said.
China needs to develop its economy and invest(投資) in high-tech. Every Chinese wants a strong country. But without blue sky, clean water and safe food, the achievements in the economy will become meaningless. Space technologies are not to be developed for building a base on Mars so that one day all human beings can migrate to the red planet because they have destroyed Earth.
What the public wants is a strong and beautiful China. Former president Hu Jintao spoke at the 18th Party Congress last November saying that great efforts must be made to promote ecological progress and build a beautiful China. The words have shown the central government's resolution to address the environment issue.
小題1:The effect of smog doesn’t include.

A．the rising of PM 2.5 readings

B．more people suffering diseases

C．the increase of people’s income

D．patients increased in hospital

小題2:Why smog has become a common concern?

A．Because people have to pay higher prices.

B．Because nobody can avoid it.

C．Because we have to develop industry.

D．Because a popular online-post discussed it.

小題3:The underlined word “they” in paragraph 6 refers to.

A．human beings	B．other plants
C．space technologies	D．industrial development

小題4:From the last two paragraphs we can infer that.

A．high-tech can completely solve the problem of pollution

B．space technologies should be developed in a large scale

C．we can move to the Mars after the earth has been destroyed

D．we must protect the environment while developing economy

Why would an animal kill itself? It seems a strange question, and yet it is one that has made some scientists curious for a long time. For there is a kind of animal called lemming（旅鼠）, that periodically killed themselves together, and no one knows just why!
The small creatures which live in the Scandinavian mountains, feed on a diet of roots and special insects and live in nests they dig underground. When their food supply is large, the lemmings live a normal and undisturbed life.
However, when the lemmings’ food supply becomes too low to support the population, a singular migration（遷徙）begins. The lemmings leave their nests in groups. Great numbers of them begin to travel across the Scandinavian plains, a journey that may last weeks. The lemmings eat everything in their path, continuing their long march until they reach the sea.
The reason for what follows remains unbelievable to naturalists. Upon reaching the coast, the lemmings do not stop but swim by the thousands into the sea. Most stay afloat only a short time before they tire, sink and drown.
A common theory for this mass self-killing is that the lemmings do not realize that the ocean is such a huge body of water in their cross-country journey, the animals must cross many smaller bodies of water, such as rivers and small lakes. They may think that the sea is just another such swimmable path to go through. But no final answer has been found to the strange happening.
小題1:The passage is mainly about______.

A．how lemmings find food

B．why animals kill themselves

C．the lemmings’ self-killing

D．the food supply in the Scandinavian mountains

小題2:A reason for the lemmings’ self-killing might be that they______.

A．go mad from a lack of food

B．hope to find fish for food

C．decide to reduce the population

D．think they can cross the sea

小題3:Why are scientists curious about the lemmings’ behavior?

A．Because they are the only animals that live in Scandinavia.

B．Because it is very unusual for animals to kill themselves.

C．Because of the amount of food they can eat on their march to the sea.

D．Because they can gather together in such huge numbers.

小題4:The underlined word “singular” means______.

A．unusual

B．single

C．wonderful

D．common
