While your pet fish may appear to be ignorant of your presence, chances are that it knows you extremely well and can probably even identify you from a crowd of human faces! At least, that is the conclusion reached by scientists the University of Oxford in the U.K. and the University of Queensland in Australia, following an extensive study of the archerfish (喷水鱼), a species of tropical fish that can be found all the way from India to Indonesia, the Philippines, and Australia.
The ability to distinguish between human faces is a complex task. That’s because we all have the same basic features — two eyes sitting above a nose and a mouth. It’s only the subtle differences that make humans distinct from one another. Since this requires a combination of both visual sense and memory, researchers had always assumed that it was a skill possessed only by those with complicated brains, i.e., humans, a few select animals — such as horses, cows, dogs, monkeys and some birds, like pigeons.
To test if this assumption was accurate, a team of scientists led by Dr. Cait Newport, Marie Curie Research Fellow in the Department of Zoology at Oxford University, decided to study fish. The aquatic (水生的) animals have small brains that lack the neocortex（大脑新皮层）, or neocortex-like structure, believed to help recognize the subtle differences between human facial features.
The team began by presenting four archerfish with images of two human faces. Initially, the fish spat randomly at both. However, they soon learned that pouring water at the one selected by the researchers earned them a food treat. After that, they focused primarily on that image. The researchers then took the experiment one step further, by introducing 44 other human faces to the mix.
To the researcher’s astonishment, the trained archerfish were able to recall the learned image almost 81% of the time. And this accuracy improved to 86% when the researchers made the identification even harder, by replacing the colored photos with a set of black and white images and hiding the shape of the head.
1.What is the conclusion of the study made by the scientists from the universities?
A. Some fish may ignore your presence.
B. Some fish can recognize your faces.
C. Some fish have complicated brains.
D. Some fish have large brains.
2.What does the underlined word “it” in Paragraph 2 refer to?
A. The ability to distinguish between human faces.
B. A combination of visual sense and memory.
C. The ability of memorizing complicated things.
D. The ability of telling beasts from birds.
3.In the experiment, the researchers trained the archerfish _______.
A. by taking photos of fish
B. by improving people’s images
C. by rewarding them with food
D. by covering their heads

Crossing your legs is an extremely common habit. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.
A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason is that crossing one leg over the other increases resistance, making it even harder for the blood to circulate and increase your blood pressure. Thus, you shouldn’t have your legs crossed for more than 15 minutes, and it’s important that you get up and walk around at least once every hour.
Crossing your legs can also lead to neck and back pain. Ideally, it’s best for our bodies to sit with our feet planted flat on the floor. When you sit with your legs crossed your hips are in a twisted position, which can cause pressure on your lower and middle back and neck.
You also might notice that when you sit with your legs crossed for long periods of time your feet and legs get painful. This is because when one leg sits on top of the other, it causes pressure on the veins and nerves in your legs and feet. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.
So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.
1.A study published in Blood Pressure Monitoring showed that .
A. crossing your legs can raise your blood pressure
B. crossing one leg over the other can increase the blood circulation
C. you should have your legs crossed once every hour
D. you should get up and walk around for more than 15 minutes
2.Crossing your legs can cause some health problems except .
A. pressure on veins and nerves in legs and feet
B. permanent nerve damage
C. unstable posture
D. neck and back pain
3.What seems to be the writer’s attitude toward crossing legs?
A. Supportive. B. Negative.

Crossing your legs is an extremely common habit. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.
A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason this happens is because the blood in your legs has to work against gravity to be pumped back to your heart, crossing one leg over the other increases resistance, making it even harder for the blood to circulate. You won’t feel any immediate effects, but sitting for long periods of time will hurt you forever.
Crossing your legs can also lead to neck and back pain. Ideally, it’s best for our bodies to sit with our feet planted flat, hip width apart, on the floor, but it’s not easy to maintain perfect posture all day at the office. When you sit with your legs crossed your hips are in a twisted position, which can cause one of your pelvic bones(骨盆) to rotate. Since your pelvic bone supports your neck and spine（脊椎）, this can cause pressure on your lower and middle back and neck.
You also might notice that when you sit with your legs crossed for long periods of time your feet and legs get painful or have the feeling of being asleep. This is because when one leg sits on top of the other it causes pressure on the veins（静脉） and nerves in your legs and feet. It can cause numbness and/or temporary paralysis in the legs, ankles, or feet. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.
So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.
1.Which of the following is not the consequence of crossing legs?
A. Neck and back get hurt.
B. Feet and legs become numb.
C. Blood pressure goes up.
D. Pelvic bones keep perfect postures.
2.What does the underlined word “rotate” in Para3 mean?
A. break seriously
B. hurt greatly
C. move casually
D. straighten suddenly
3.What does the text mainly talk about?
A. How to choose a proper sitting posture
B. It is advisable not to sit with legs crossed
C. How to develop beneficial habits
D. Blood pressure harms our bodies.
