We already have iris(虹膜) and fingerprint scanning but noses could be an even better method of identification, says a study from the University of Bath, UK.

The researchers scanned noses in 3D and characterized  them. They found 6 main nose types: Roman, Greek, Nubian, hawk, snub and turn-up. Since they are hard to hide, the study says, noses would work well for identification.

The researchers say noses have been overlooked in the growing field of biometrics, studies into ways of identifying distinguishing characters of people. "Noses are out standing facial features and yet their use as a biometric has been largely unexplored," said the University of Bath's Dr Adrian Evans. "Ears have been looked at in detail, eyes have been looked at in terms of iris recognition but the nose has been ignored."

The researchers used a system called PhotoFace, developed by researchers at the University of the West of England in Bristol, for the 3D scans.

Several measurements by which noses can be recognised were identified and the team developed recognition software based on these parameters(范圍)

" This initial work is nowhere as good as iris identification but the nose has pros and cons," said Dr Evans.

There's no magic biometric that solves all your problems. Irises are a powerful biometric but can be difficult to get accurately and can be easily covered by eyelids or glasses. People can easily cover up their ears, with their hair for example.

"Of course you can have a broken nose or wear a false nose or have plastic surgery but to have nose surgery to change your identity is fairly obvious. Irises are very good for recognition but you can put in dilation drops which change the iris completely. Not all techniques are reliable," he said.

The research is based on a study of 40 noses and the data base has now been expanded to 160 for further tests to see if the software can pick out people from a larger group and distinguish between relatives.

Dr Evans hopes the method can be proven to be effective on this larger sample. "The technique certainly shows potential, perhaps to be used in combination with other identification methods," he said.

57. Where can you probably read this article?

In a newspaper about education.

In a newspaper about science

In a newspaper about software

In a newspaper about dress-up

58.  Which is true according to the passage?

Dr Adrian Evans works at the University of the West of England in Bristol,

The researchers used a system called Photoshop for the 3D scans.

The research is based on a study of 160 noses.

The research team developed their own recognition software.

59. The word overlooked in the third paragraph possibly means:

A. well-studied          B. carefully-scanned

C. wholly-recognized     D. carelessly-studied

60. We can infer from the last three paragraphs that_________.

The consequence of the method remains to be seen

Dr Evans is sure that the method can be used to pick out uncles and nephews.

More new soft wares will be developed to do the research.

This method can still be used if your nose is broken,

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.  The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard. Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example. But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But is also applies to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
【小題1】What does the underlined phrase “over-consumption” refer to?

A．Using too much packaging.
B．Recycling too many wastes.
C．Making more products than necessary.
D．Having more material than is needed.
【小題2】The author uses figures in Paragraph 2 to show _______.
A．the tendency of cutting household waste
B．the increase of packaging recycling
C．the rapid growth of super markets
D．the fact of packaging overuse
【小題3】According to the text, recycling ______.   
A．helps control the greenhouse effect
B．means burning packaging for energy
C．is the solution to gas shortage
D．leads to a waste of land
【小題4】What can be inferred from Paragraph 4?   
A．Unpackaged products are of bad quality.
B．Supermarkets care more about packaging.
C．It is improper to judge quality by packaging.
D．Other products are better packaged than food.
【小題5】What can we learn from the last paragraph?

科目：高中英語 來源：2011-2012學年廣東省高三上學期期中考試英語題 題型：閱讀理解

If you feel at present that you don’t have enough friends in your life，one reason may be that you have let yourself become too busy to make time for the relationships you already have.

Starting and keeping friendship requires effort and commitment．Many of us let our lives become so busy with work and other commitments that we don’t get around to scheduling time for pleasure and renewal（敘舊，更新）with the friends，relatives and acquaintances we already have．

Making the effort to call your friends more regularly and to accept more of the invitations you receive from others can improve your social life in a hurry!

Are there any people you could call right now and be assured of a pleasant welcome? Are there people that you could count on to help you in time of difficulty? Can you have close talks with them? Do you have fun when you are together? Are you happy to have them in your life?

If you haven’t seen much of them lately, is it because you have become too busy? Have you grown apart? Was there an argument?

If the main reason you haven’t been getting together with the people you already know is because you have gotten too busy, take a good look at how you spend your time．Compare it with your real values and priorities（優(yōu)先考慮的事）in life．Is your busy lifestyle really bringing you the quality of life that you want?

If you have become too busy for friends，why has this happened? Are you seeking material toys in your life at the expense of relationships with other human beings? Have you allowed your time to be over-committed because you never say “No” to anyone? Do you insist on doing things yourself that could be delegated to others? If so, why? Do you believe that everything depends on you?

Examine whether the way you are now spending your time accurately reflects your deepest values and priorities．Make sure that you schedule adequate time for the things that are truly most important to you．

If you really want to keep friends in your life, make a space in your schedule, and a space in your heart for them.

①Researches show what we already suspected: Three out of four babies who died of SIDS(嬰兒猝死) involved co-sleeping. We’ll say it again. The safest course is not to sleep with babies.

②We know the argument: Bad parenting, not co-sleeping, is to blame for the dozens of babies’ deaths. Some parents stick to co-sleeping because it helps them bond with their newborns. They say those who give co-sleeping a bad name either had been drinking, used drugs or were too tired to notice that they rolled over on their children.

③But, most of the cases did not involve drugs or alcohol. There’s a “but” here, however. Submitting to a test for drugs or alcohol in these cases is voluntary, so it’s difficult to know with certainty.

④Organizations like the Black Health Coalition and others have explained the safe way to co-sleep. While we understand those arguments, we also know that mistakes can happen and that it only takes one time for something to go terribly wrong. The risk outweighs the benefit.

⑤In all likelihood, parents will continue to co-sleep, and some will do so without ever having an incident, but babies are too vulnerable(易受傷的) for parents to take such chances. Therefore, the best place for babies to sleep is in their own beds, on their backs, with no pillows, blankets or toys. No parent wants a tragedy to occur. The best way to make sure the tragedy doesn’t happen is to allow babies to sleep alone in their own cribs.                                         

1.According to the author, most of the SIDS cases happened because of ________.

A. drugs    B. co-sleeping    C. drinking     D. bad parenting

2. Some parents think sleeping with their babies can ________.

A. keep the babies healthy

B. give co-sleeping a good name

C. prevent themselves from drinking

D. develop a good relation with their babies

3. The author holds the opinion that ________.

A. parents can sleep with babies, but cautiously

B. co-sleep helps to bring babies closer to parents

C. parents can’t take chances to sleep with their babies

D. accidents only happen to those careless parents

4. Which of the following best describes the structure of the text?

A.  ①         B.  ①②      C.  ①         D.  ①

↙↘              ↓         ↙↓↘        ↙↓↓↘

②③  ④        ③④    ②③④       ②③④⑤
