【題目】According to a team of researchers, an animals' ability to perceive(感知)time is linked to their pace of life.

"Our results lend support to the importance of time perception in animals where the ability to

perceive time in a very short time may be the difference between life and death for fast moving

creatures." commented lead author Kevin Healy from Trinity College Dublin.

The study was done with a variety of animals using a phenomenon based on the maximum speed of flashes of light an individual can see before the light source is seen as constant. Dogs, for example, have eyes with a refresh rate higher than humans.

One example of this phenomenon at work, the authors say, is the housefly and its ability to avoid being hit. The research showed flies "observe motion in a shorter time than our own eyes can achieve," which allows them to avoid being hit.

Professor Graeme Ruxton of the University of St Andrews in Scotland, who worked jointly(共同地) on the research project, said in a statement, "Having eyes that send updates to the brain at much higher frequencies than our eyes do is of no value if the brain cannot process that information equally quickly. Thus, this work highlights the impressive abilities of even the smallest animal brains. Flies might not be deep thinkers, but they can make good decisions very quickly."

In comparison the tiger beetle(虎甲蟲(chóng))runs faster than its eyes can keep up, basically becoming blind, which requires it to stop periodically to re-evaluate its prey's(獵物)position.

Our results suggest that time perception offers an as yet unstudied dimension along which

animals can specialize and there is considerable range to study this system in more detail.

【1】What is the research mentioned in the passage mainly about?

A. Pace of life of animals. B. Time perception of animals.

C. Lifetime of small animals. D. Impressive abilities of animals.

【2】Why can houseflies avoid being hit?

A. They can think very deeply before they act.

B. They can fly much faster than their eyes can keep up.

C. They can process the information as quickly as they receive it.

D. They can send information to brain more quickly than to their eyes.

【3】What will a tiger beetle have to do to catch a moving prey?

A. Try to run as fast as it can. B. Prevent itself from becoming blind.

C. Slow down to gain its time perception. D. Stop occasionally to spot the prey again.

【答案】

【1】B

【2】C

【3】D

【解析】文章主要講述了研究小組發(fā)現(xiàn)動(dòng)物對(duì)時(shí)間的感知能力源于它們的生活節(jié)奏，但這是一個(gè)未知的領(lǐng)域，需要進(jìn)一步去研究。

【1】主旨大意題。根據(jù)文章最后一段“Our results suggest that time perception offers an as yet unstudied dimension along which animals can specialize and there is considerable range to study this system in more detail.”通過(guò)動(dòng)物對(duì)時(shí)間的感知的研究表明，這是一個(gè)未知的領(lǐng)域，需要我們進(jìn)一步的研究。故選B。

【2】推理判斷題。根據(jù)第四段中的“The research showed flies “observe motion in a shorter time than our own eyes can achieve,” which allows them to avoid being hit.”研究顯示蒼蠅“比我們能在更短的時(shí)間內(nèi)觀察到運(yùn)動(dòng)”，這讓它們能避免被擊中。及第五段中的“Flies might not be deep thinkers, but they can make good decisions very quickly.”蒼蠅可能不是很好的思考者， 但它們可以很快做出好的決定�？赏浦�，蒼蠅能避免被擊中，是因?yàn)樗鼈兡芰⒓刺幚硎盏降男畔�。故選C。

【3】細(xì)節(jié)理解題。根據(jù)倒數(shù)第二段中“…the tiger beetle (虎甲蟲(chóng)）runs faster than its eyes can keep up, basically becoming blind, which requires it to stop periodically to re-evaluate its prey’s (獵物)position.”虎甲蟲(chóng)移動(dòng)的比它的眼睛快，基本上是盲目的，這就要求它不時(shí)地停下來(lái)，重新評(píng)估它獵物的位置�？芍⒓紫x(chóng)為了抓住移動(dòng)的獵物，需要不時(shí)地停下來(lái)再次確定獵物的位置。故選D。

【題目】閱讀下列短文，從每題所給的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)。 Some veterinary (獸醫(yī)的) professionals voted on the best dogs for new owners.
The Golden Retriever is the No. 1 choice of veterinarians for new dog owners. His sweet, gentle and people-pleasing personality makes him a delightful addition to most families. He loves to play, displays loyalty and love — and, if those are not enough, this guy is a real looker. Those good looks come at a price, though: His gorgeous coat needs regular brushing and bathing.
Smart, energetic, sensible and entertaining, the Poodle is another breed that's great for the beginner dog owners. Poodles have a reputation for being a bit aloof with people they don't know, but we just think they're less “needy”. He's available in three sizes, but whatever size you choose, be aware that if you want his curly coat in anything but a basic cut, you're going to spend a lot of time going to the groomer (美容師).
The lovable Lab has been a favorite breed in the US for more than 20 years, and it would appear that vets agree with this choice, naming him the No.3 best breed for new dog owners. This friendly breed is a popular choice for service and therapy dogs, and his strength makes him an excellent hunting dog and good athlete. These beauties are best suited to active families.
The Cavalier is a popular toy breed. He loves people, whether that involves sitting on laps or going for long walks. The Cavalier is happy, trusting and eas-going, making friends everywhere he goes. Although he can be stubborn, he generally tends to be adaptable enough to sit quietly with an older person, then turn around and play with an active child.
The Bichon Frise was bred specifically to be a companion, so there is little surprise that veterinarians consider him as such a great choice for new dog owners. Wonderfully affectionate (深情的) and endlessly entertaining, he has long been a popular circus performer, but he'll be perfectly happy performing his tricks for his family at home.
（1）The Golden Retriever is the veterinarians' first choice because __________.
A.it doesn't cost much

B.it doesn't need much care

C.it is sweet and good-looking
D.it is helpful to watch out for their houses
（2）The underlined word “aloof” in Paragraph 3 means __________.
A.lovely
B.naughty
C.fierce
D.cold
（3）We can infer that the lovable Lab is___________.
A.unsuitable for people who want a service dog
B.popular in the US mainly because of its gorgeous look
C.often used as a therapy dog because of its quiet personality
D.a good choice for people who enjoy taking a dog on their adventures
（4）What can be implied about the Cavalier in the passage?
A.It can never sit quietly for a long time.
B.It is suitable for both old people and children.
C.It often appears scary to both dogs and people.
D.It is inappropriate for new dog owners because it's too stubborn.
（5）The text is developed by___________.
A.listing some examples
B.presenting some proofs
C.showing some phenomena
D.giving some suggestions

【題目】Golden lion tamarins (GLT) are among the most endangered animals on earth. They have fur which ranges in color from reddish orange to golden brown. They are the smallest monkeys in the world，and they weigh only half a kilogram. They move quickly through the forest. Each group of these delightful creatures needs a living space of about two square kilometres of thick forest. They are named after lions because of the ring of fur around their faces. Their only natural habitat(棲息地)is the Atlantic forest in Brazil.

Sadly，it is unusual to see a GLT nowadays，and there are very few of them left because they are hunted for the pet trade. In addition，the rapid expansion in the human population has resulted in the need for more land to grow crops，leaving them homeless.

GLTs live in close family groups. In the1970s，the Brazilian scientist，Eduardo Figueiro， realized what was happening to this rare animal，and began trying to save them，which has been supported by the government. He said，“It's so important to protect the animal，who evolved more than 20 million years ago. The worst problem is that the monkeys cannot travel without tree cover. It is trees that connect these groups. In this way，the monkeys can meet and socialize with each other. " Meanwhile , special patrols(巡邏) have been organized by government in the reserves to prevent hunting and forest fires.

As a result of these actions，the number of GLTs has grown to about 1500. There are also another 450 living in zoos throughout the world. Here they can be seen living in happy and close family groups，with the male gently taking much of the responsibility for the young.

【1】The main idea of Paragraph 1 is GLTs' .

A. main characteristics B. present situations

C. value D. habitat

【2】According to Figueiro，to save GLTs the most important thing is to .

A. prevent forest fires B. keep as many trees as possible

C. educate people to stop hunting them D. make them live in close family groups

【3】What can be inferred from the text

A. GLTs are dying out nowadays.

B. Some GLTs feed on tree leaves.

C. Some GLTs are living in the Atlantic forest.

D. Brazil has been taking active actions to save GLTs.

【4】We can conclude from the text that zoos

A. keep GLTs to separate them from each other

B. have taken a key role in the pet trade of GLTs

C. are helping raise GLTs to increase their population

D. catch GLTs and kill them cruelly to get their fur

【題目】請(qǐng)閱讀下列短文，從每題所給的四個(gè)選項(xiàng)(A、B、C和D)中，選出最佳選項(xiàng)。
C
Hong Kong, a city of seven million---and growing fast. By the year 2050 Hong Kong’s population will almost double. Where will these people live?
There's only one place to go---up. Fast forward 50 years. This is the tallest man-made structure on the planet. Its name: Millennium Tower. It would stand twice as tall as anything built before. Over 60 thousand people would live or work here. Millennium's designers think it represents the best solution for the coming population explosion.
It would cost ten billion dollars and consume more building materials than any single nation could produce. David Nelson, one of Millennium's key designers, said: “It would be a massive project and a world project. But to actually realize it resources would have to come from all over the globe. The challenge and the motivation for doing it would be to realize one of the world's largest and most complex construction projects.”
Millennium would be more complex than anything ever built. So its builders won't know for sure the building is safe until it's up, and they can't afford to make an error. Massive earthquakes have brought down entire cities in this part of the world. Can Millennium's designers make it immune to these quakes of the earth?
For Millennium, like all the other buildings, safety is just one concern among many. It will need to be a home, one that welcomes people in. Getting people into the building and making sure they have a great experience well be what makes Millennium successful, but how to do it? For the design team, the secret was to bring all the elements of city life within. Cafes and restaurants, theatres and stores would provide entertainment. Health clubs, even schools and medical clinics would also serve the towers’ residents.
Millennium's designers have proven something. Things that seem impossible today, might just become reality tomorrow. The engineering problems have, for the most part, already been solved. Our achievements are limited only by our imaginations.
（1）Why did the designers decide to build Millennium?
A.Because they wanted to build the world's most complex building.
B.Because Hong Kong's population will greatly increase.
C.Because Hong Kong is developing fast as an international city.
D.Because it can bring huge profit after it is put to use.
（2）What is TRUE about the project?
A.It will be completed in the year 2050.
B.It can accommodate all the residents in Hong Kong.
C.It is designed by designers from all over the globe.
D.It has to be strong enough to stand earthquakes.
（3）The success of Millennium mainly relies on_______.
A.how many resources will be used
B.how many nations will work together
C.whether people can enjoy their life in it
D.whether it is safe for people to live in
（4）How does the writer develop this passage?
A.By providing descriptions.
B.By using figures.
C.By giving examples.
D.By analyzing causes..
