In the near future,we may be using our eyes to operate our smart-phones and tablets,even when it comes to playing popular games like Fruit Ninja.
The Gaze Group has been developing eye-controlled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities,and are very expensive.
“After a while,we figured out that probably the best way is to go for a mass-market way,” says Gaze’s Sune Alstrup Johansen.“where everybody would have this available."
Johansen and some of his colleagues have formed a new company,the Eye Tribe,which is hoping to develop the technology on a mass commercial level.
The technology works with the help of the computing device toward the user’s face. After making sure of the user’s eye movements,the technology is then able to easily find where a person’s eyes are moving,and then allow the eyes to control a cursor(光标).
“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at,“reads an explanation on the Eye Tribe site.
There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world.Recently Xbox released the Kinect device,which lets users control their Xbox and play certain games using only their hands,legs and voices. But still,most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device.Johansen said a replaceable filter(滤光器)would be a cheap,convenient way for most consumers.
And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

D
A fish may not be the first creature that comes to mind when co-operation in the animal world is mentioned, but a new study has shown the caring behavior of one sea species. Scientists have found that pairs of rabbitfishes will help and support each other while feeding. While such behavior has been recorded for birds and mammals, it had formerly been thought to be impossible for fishes to exhibit the same features.
"We found that rabbitfish pairs manage their caring activity quite firmly, thus providing safety for their partner that is looking for food," says Dr. Simon Brandl. "In other words, one partner stays ‘on guard’ while the other feeds – these fishes just watch each others’ back," Dr. Brandl says. "This behavior is so far unique among fishes and appears to be based on reciprocal cooperation between pair members."
Reciprocal cooperation, which requires an investment in a partner that is later reciprocated(报答), is supposed to require complex cognitive and social skills — something that fishes had been considered not to have until now.
Dr. Brandl says the research shows clear support and presents interesting evidence for reciprocal support between the rabbitfish pairs.
"There has been a long debate about whether reciprocal cooperation can exist in animals that lack the highly developed cognitive and social skills found in humans and a few species of birds and primates," he said. "By showing that fishes — which are commonly considered to be cold, unsocial, and unintelligent — are able to have reciprocal cooperative systems, we provide evidence that cooperation may not be as special as earlier expected."
Professor Bellwood says that our opinion of fishes as cold creatures is slowly changing. "Our findings should further cause efforts to understand fishes as highly developed organisms with complex social behaviors. This may also require a change in how we study and treat fishes."
【题文1】 What does the first paragraph imply?
A. Rabbitfishes almost act like birds and mammals.
B. Fishes don’t belong to the animal world at all.
C. Fishes have the ability to feed each other.
D. The caring behavior is impossible for fishes.
【题文2】While one rabbitfish feeds, the other one _________.
A. is protecting its partner from any danger B. is carrying some food for its partner
C. is looking for more food for its partner D. is hiding behind the back of its partner
【题文3】 What did people use to think about fishes?
A. They have the same behaviors. B. They show no feelings for others.
C. They have high social skills. D. They support each other all the time.
【题文4】What can we infer from what Bellwood said?
A. We should change our way of eating fish.
B. The behaviors of fishes are difficult to learn.
C. More efforts are needed to understand fish.
D. Our study of social behaviors should be careful.

高三英语单项填空简单题查看答案及解析
DNA left at a crime scene could be used in the future to build up a picture of an offender’s face, it was revealed tonight.
A first step towards genetic mugshots has been taken by researchers in the US who link specific DNA markers with face shape. To identify the genes, they focused on known mutations(突变) that cause changes of the face and head. Normal versions of these genes were found to influence individual features. For instance, one gene affected the lips, another the shape and configuration of bones around the eyes, and a third the appearance of the mid-face and skull. In total, 20 genes had “significant effects” on facial appearance.
Lead scientist Professor Mark Shriver, from Pennsylvania State University, said: “We use DNA to match to an individual or identify an individual, but you can get so much more from DNA. Currently we can’t go from DNA to a face, or from a face to DNA, but it should be possible.” The implications are far reaching, raising the possibility of creating a data bank of facial types based on genetic markers. DNA from a crime scene could then be used to produce a rough image of the face of an offender or victim. Such genetic mugshots may be more reliable than computer-generated “e-fits” based on witnesses’ recollections. Other uses of the technique might include proving the identity of fathers in paternity cases, or visualising our remote ancestors from fossil DNA.
The scientists wrote in the online journal Public Library of Science Genetics: “Such predictive modelling could be forensically useful; for example, DNA left at crime scenes could be tested and faces predicted in order to help to narrow the pool of potential suspects. Further, our methods could be used to predict the facial features of descendants, deceased ancestors, and even extinct human species. In addition, these methods could prove to be useful diagnostic tools.” The team developed a model which first established a range of physical face shapes from people of mixed West African and European ancestry from the US, Brazil and Cape Verde. Measurements were taken of thousands of point co-ordinates on grids placed over 3D images of the faces.
Statistical methods were then used to determine the relationship between facial differences and the effects of gender, ethnic ancestry and individual gene variants.
1.The underlined word “mugshots” in the second paragraph most probably means _________.
A. different faces B. characteristics C. pictures of faces D. genders
2.What can be inferred from the passage?
A. DNA has been used to build up a picture of an offender’s face.
B. It may be much easier to catch criminals with the help of DNA.
C. In all, 20 genes had “significant effects” on facial appearance.
D. One gene can affect more than one part of your face.
3.According to Professor Mark Shriver, we know_________.
A. they can merely match to an individual or identify an individual
B. there is a possibility of going from DNA to a face
C. DNA could be used to produce a rough image of an offender’s face
D. this technology is more reliable than computer-generated “e-fits”
4.What is the most possible title of the passage?
A. Creating a data bank of DNA
B. Recognizing the DNA of criminals
C. Predicting the location of offence using DNA
D. Building image of offender’s face from DNA
