If you think about the countless number of animal species on our planet, the giraffe is perhaps one of the most interesting. With its unusual pattern and incredibly long neck, it looks like no other animal on Earth. But how did this mammal come to get its famously huge neck? Well, scientists have been asking themselves this question for centuries.
The most commonly believed answer is that the massive neck — which measures on average 180 centimeters and weighs about 270 kilograms — evolved to allow the animal to reach the leaves of tall trees.
British scientist Charles Darwin was one of the first people to propose this idea in the 1800s.“The giraffe… has its whole frame beautifully adapted for browsing on the higher branches of trees,”he wrote in his famous 1859 book On the Origin of Species. It was Darwin’s belief that the giraffe once had a much shorter neck, but over time, evolution led to longer-necked giraffes being born, which in turn survived as they were able to reach the food that others couldn’t. Yet, there are other theories. According to a paper published in September in the Journal of Arid Environments, the giraffe’s neck evolved to increase its surface-area-to-volume ratio. Because the animal’s neck increases its body’s surface area, it makes it easier for it to keep cool, the paper’s authors wrote. This phenomenon can be seen everywhere in nature, and even in engineering.
For example, this is why elephants have such large ears, and why radiators (暖气片) in homes are flat and thin, as a large surface area allows heat to escape quicker.
Meanwhile, some believe that competition is the answer. A 1996 study by two South African zoologists argued that the male giraffes with the biggest necks are the ones who “win” access to females to reproduce, as they are better at fighting, meaning that their long necks are passed down through the generations. So, it seems like there’s still no definite answer to the question. But until we find the truth, we should at least enjoy this beautiful and interesting creature for what it is today, rather than wonder about where it came from.
1.What idea did Charles Darwin put forward in his book?
A.Giraffe’s necks are 180 cm long and weigh 270 kg on average.
B.Giraffes with a long neck are better at fighting.
C.Giraffes are a species that is born with a long neck.
D.Longer-necked giraffes are able to survive better.
2.What is the article mainly about?
A.Charles Darwin’s theory of evolution.
B.Different functions of the giraffe’s long neck.
C.How the giraffe manages to survive in nature.
D.Theories about why the giraffe has a huge neck.

It’s interesting when you think about how Japan is a nation that appreciates the virtues of silence and good manners, and yet when it comes to eating noodles, Japanese people can be the loudest in the world.
According to lifestyle website grapee.jp, slurping when eating noodles is encouraged in Japanese culture. It’s believed that taking air into your mouth can enhance the flavor of the noodles, and that it helps cool down the noodles. It’s also considered to be a way to show appreciation for the dish. Sometimes, just making the noise alone seems to make the noodles more enjoyable.
It wasn’t until a new expression - “noodle harassment” ,or “hu-hara” in Japanese - came out last year on social media that Japanese people started to realize that the slurping noise is making some foreign visitors uncomfortable.
As a response, Japanese instant noodle maker Nissin introduced a so-called noise-canceling fork earlier this year. The fork, which looks like an electric toothbrush, is connected wirelessly to a smartphone. When the person using the fork starts to slurp, the fork sends a signal to the person’s phone, making it play a sound to mask the slurping noise.
“The fork is a solution to the ‘noodle harassment’ issue, particularly as the number of tourists visiting Japan increases,” said the company, according to Euro News.
But is it really necessary?
Dining traditions do vary. What’s considered to be proper table manners in one country is likely to be seen as rude in another. In India, for example, people eat with their hands because they think in this way they build a connection with the food. However, people who are used to eating with utensils（餐具）might find it uncomfortable to get their hands covered with oil and bits of food. But this eating method is part of India’s culture, just like Japan’s slurping is part of its own.
“So, if you are eating noodles, whether that's ramen（拉面）, udon（乌冬面）, or soba（荞麦面）, please slurp,” wrote the reporter Brian Ashcraft on blog Kotaku. “If anyone gets annoyed while you are doing that, pay them no mind because they’re missing the point entirely.”
1.Which of the following does not contribute to the popularity of slurping?
A. It is helpful to cool down the noodles.
B. It helps to draw other people’s attention.
C. It can strengthen the flavor of the noodles.
D. It is a way to show enjoyment from the noodles.
2.Which of the following best explains “harassment” underlined in Paragraph 3?
A. Digest. B. Enjoyment. C. Annoyance. D. Embarrassment.
3.Why is the eating method of India mentioned?
A. To inform readers of Indians’ dining habit.
B. To show that Indians are rude about eating.
C. To present similarity between Japan and India.
D. To provide an example of various eating traditions.
4.What is implied according to Brian Ashcraft?
A. It is impolite to ignore other people's anger.
B. Japanese shouldn’t slurp when eating noodles.
C. It is necessary to respect different eating cultures.
D. People cannot understand the pleasure of slurping at all.

When many people in the west think of China, the animal that they think of is the dragon. For them, the dragon is an aggressive monster that breathes fire. Many popular legends tell how dragons have killed brave knights and eaten beautiful young girls.
For Chinese people, however, the dragon is not an evil monster. It’s a cultural and spiritual symbol for prosperity and good luck. The dragon’s main task is to create harmony and bring rain. Dragons are celebrated in art and architecture, and of course the dragon dance is a very popular ritual (仪式).
China isn’t the only country to have the dragon as its symbol. Wales in the UK, has a red dragon proudly displayed on its flag. Another country in the world with a dragon on its flag is Bhutan, a tiny country between China and India.
Almost all countries in the world have an animal symbol representing their countries. This is particularly obvious during sports. The English think lions to be brave and proud animal and the English football teams have three lions on their football shirts.
Australia is famous for kangaroos, of course. The national rugby team is more commonly known as the Wallabies, a type of small kangaroo.The South African team is known as the Springboks, a type of African antelope. Likewise the New Zealanders, whether playing sports or not, are commonly known as kiwis. A kiwi is a native New Zealand bird that can’t fly.
All countries are proud of their symbols, which they feel reflect national characteristics or the beauty and variety of their natural environments. Recently, a Shang hai professor claimed that using the dragon as a national symbol could make western countries have a negative view of China. But in an Internet survey 90% of Chinese people wanted to keep the dragon.
1.In the opinion of the west, the dragon is ______.
A．a terrible animal that is not popular
B．a cultural and spiritual symbol of good luck
C．a reflection of China’s national characteristics
D．an animal that can create harmony and bring rain
2.Which of the following does NOT use the dragon as its national symbol?
A．China. B．Wales. C．Bhutan. D．India.
3.According to the passage, which of the following statements is TRUE?
A．The national rugby team from the South Africa is well known as the Wallabies.
B．The Australian team is known as Springboks, a type of kangaroo.
C．The New Zealanders are commonly known as kiwis only when playing sports.
D．The dragon is mentioned to have been used on the flag in two countries.

高二英语单项填空中等难度题查看答案及解析
When you think about math, you probably don’t think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals.
People who solve crimes look for patterns that might reveal(揭示) the identity of the criminal. It’s long been believed, for example, that criminals will break the law closer to where they live, simply because it’s easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect(嫌疑犯) who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it.
But Mike O’Leary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of a criminal’s home base by combining these patterns with a city’s layout(布局) and historical crime records.
The records of past crimes contain geographical information and can reveal easy targets — that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersections are. O’Leary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminal’s patterns change with age. It’s been shown, for example, that the younger the criminal, the closer to home the crime.
Other computer programmers have worked on similar software, but O’Leary’s uses more math. The mathematician plans to make his computer program available, free of charge, to police departments around the country.
The program is just one way to use math to fight crime. O’Leary says that criminology — the study of crime and criminals — contains a lot of good math problems. “I feel like I’m in a gold mine and I’m the only one who knows what gold looks like,” he says. “It’s a lot of fun.”
1.
To find criminals, police usually ______.
A. focus on where crimes take place B. seek help from local people
C. depend on new mathematical tools D. check who are on the crime scene
2.
O’Leary is writing a computer program that ______.
A. uses math to increase the speed of calculation
B. tells the identity of a criminal in a certain area
C. shows changes in criminals’ patterns
D. provides the crime records of a given city
3.
By “I’m the only one who knows what gold looks like”, O’Leary means that he ______.
A. is better at finding gold than others
B. is the only one who uses math to make money
C. knows more criminals than other mathematicians
D. knows best how to use math to help solve crimes
4.
What is the main idea of the text?
A. Criminals live near where crimes occur.
B. Math could help police find criminals.
C. Crime records could be used to fight crime.
D. Computer software works in preventing crimes.
