Faces show emotions. Psychology; computer science, and engineering researchers are joining forces to teach machines to read expressions. If they succeed, your computer may one day "read" your mood and cooperate. Machines equipped with emotional skills could also be used in teaching , robotics, gaming, security, and for psychological diagnoses(诊断).
"Mind Reader", a system developed by Rosalind Picard at the Massachusetts Institute of Technology in the US, uses input from a video camera to do real-time analysis of facial expressions. It reports on whether you seem "interested" or “agreeable” or if you're "confused".
The system can help people detect others' emotions. Picard says this means we could teach a machine to be as sensitive as a human. In fact, a machine can be even smarter: than people since it can tell if a person is lying or just "performing" by analyzing one's facial movements. Jeffrey Cohn, a psychologist at the University of Pittsburgh, uses the Facial Action Coding System to detect human emotions. "The face is always visible," Cohn says, "People communicate a lot about feelings and thoughts through facial expression."
Cohn studied a videotape of criminal who professed to be sad about the murder of several family members and tried to pin the blame on some one else． But Cohn saw no real sadness in the woman's face. Sadness is a combination of facial action units that are difficult to do voluntarily. This means, even though your mouth lies, your face doesn't, and the machine will know it all.

　　Zinc(锌) is one of about 20 elements necessary for good health. It is present in the body in a very small amount but makes it possible for important chemical actions to be carried out in cells. Scientists are just beginning to discover how zinc and other elements work.

　　Researchers first studied zinc as a way to speed recovery. Dr. Waltor Powys formerly with the United States Air Force noted that the laboratory animals recovered faster when some matters were added to their food. One of these matters was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate(硫酸盐) recovered in half of the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by lack of zinc in the body. They treated these disorders successfully by giving the patients zinc sulphate.

　　The amount of zinc in the body can be found by examining blood and hair. A lack of this important element is not uncommon among people in both industrial and developing countries. Zinc is found in most high protein(蛋白质) foods such as meat, milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these food. Food markets should add these elements so that more people could get needed amount of these necessary matters.

1. Which of the following statements is true?

　　A. Scientists found how zinc works a long time ago.

　　B. People need a large amount of zinc to be healthy.

　　C. Zinc allows important chemical actions to take place in cells.

　　D. Zinc must be used in the course of medical operation.

2. One of the results from the study of zinc is that _______.

　　A. there’s only a little zinc in the human body

　　B. food rich in protein contains more zinc

　　C. some physical problems are caused by lack of zinc

　　D. any patient who receives zinc sulphate gets well immediately

3. The best title for the passage may be _______.

     A. A New Discovery                               B. Zinc and Health

     C. How Zinc Works                               D. Add Zinc to Your Food

Archaeologists believe they are on the turning point of throwing light on the life of William Shakespeare — by excavating （发掘） what may have been the playwright’s dust hole．
Experts have begun excavating the ruins of New Place, Shakespeare’s former home in Stratford-upon-Avon, which was destroyed 250 years ago．Although little remains of the property, the team, led by Birmingham Archaeology, believes it has identified a dust hole used by the 16th century poet．[来源:学*科*网]
Small pieces of pottery （陶瓷） and broken clay pipe have already been found from a muddy hole on the site, which they claim could yield some of the most significant discoveries about Shakespeare in decades．The dig focuses on three areas of the property, which Shakespeare bought in 1597 when he returned to his home town from London having achieved fame — including the so-called knot garden at the back of the building．
Dr Diana Owen, Director of the Shakespeare Birthplace Trust, which owns the site, said, “We do not know if the knot garden was an area used by Shakespeare — it may have been a yard simply used by his servants．But this could actually yield some fantastic results, especially if it was an area where rubbish was thrown or the dust hole was located．”
Kevin Colls, from Birmingham Archaeology, added, “Through documentary evidence we know Shakespeare lived at New Place but we have very little information regarding the layout （布局） of the house and gardens at this time．Through archaeological fieldwork, in particular the dig of structural remains and the recovery of artefacts, we hope to fill in the blanks．”
Until October, visitors will be able to watch archaeologists and volunteers at work as they excavate the remains of the house, which was knocked down in 1759．Experts hope to unearth evidence to support theories that Shakespeare wrote many of his most famous works at the property．
71．This excavation intends to ______．
A．know something about the playwright’s dust hole
B．search for some treasure in the dust hole
C．explore the life of William Shakespeare
D．find something that Shakespeare lost
72．New Place was destroyed in the ______ century．
A．15th     B．16th     C．17th      D．18th
73．Small pieces of pottery and broken clay pipe on the site ______．
A．could show Shakespeare’s luxurious life
B．could lead to important discoveries about Shakespeare
C．could show us that Shakespeare lived at New Place
D．could prove when New Place was knocked down
74．The underlined phrase “the blanks” in Paragraph 5 refers to ______．
A．the ruins of New Place 
B．the smallest pieces of broken pottery
C．three areas of the property 
D．the layout of the house and gardens of New Place
75．What can we learn from the text?
A．Shakespeare used to live at New Place．
B．Shakespeare became famous after 1597．
C．Only his servants used the knot garden．
D．Dr Diana Owen owns Shakespeare’s property．

There is a saying in French—“Si vieillesse pouvait, si jeunesse savait”—which means roughly “if age had the ability, if youth had the knowledge.” I was reminded of this saying the other day when I saw an interview with a distinguished Asian neurosurgeon(神经外科医生), now retired, about the impact of computer technology on modern surgery.
He was referring to the difficulty people of his age had in using the new techniques, but also to the fact that younger surgeons, who are more comfortable with the technology, lack some of the wisdom of experience.
It struck me that this problem is not just confined(局限于) to specialized fields such as medicine, but is widespread in modern life. There are many areas where the rapid growth of technology has widened the generation gap.
Young people are at ease with modern technology and propose all sorts of ways for using and developing it. But they often lack the experience needed to see further into the future to the possible dangers that a particular development may cause.
Older people see all sorts of difficulties and dangers, but are sometimes ignored, or even accused of being against progress, if they point out potential problems. Equally, they may see potential uses, but not have the technical skills to put them into practice themselves or the trust in the younger generation to do so.
Enthusiasm and inexperience come into conflict with caution and arrogance, usually with unsatisfactory results for both sides.
What is needed is the development of a partnership, based on mutual respect, which can deliver real progress by combining enthusiasm and caution in a constructive way, rather than in conflict with each other. The old need to give the younger generation the time, the resources and, above all, the authority to develop new ideas and use their skills. In exchange, the young need to turn more actively to the older generation to seek their advice and exploit their greater experience of the world in foreseeing and overcoming potential problems.
【小题1】The passage is mainly about ________.

Even if you are naturally shy, these three tricks will help you to quickly build a new social circle in any new city.

1. Take pictures

One of the great things about taking pictures at an event or party is that it gives you an excuse to get in touch with the person later. Everybody loves seeing pictures of themselves, and it’s very easy after taking a picture to say “If you’d like I can email it to you”. This can be the seed that leads to new connections. The next time you hear about a fun event email your new contacts to let them know about it.

2. Eat alone in public

You might feel self-conscious eating by yourself but it has an important benefit: you are much easier to approach when you are alone. People may be afraid of interrupting you or being rude if you are in a conversation with someone else. Bring a book or newspaper to read (this will make you feel less self-conscious). Plus, having an interesting book with you will give others an excuse to start a conversation if they’ve read it.

3. Join a class, sports team, or club

Yoga, salsa dancing, volleyball, Toastmasters (a public speaking club), a class for work, etc. Take up a new hobby or continue an old one!

These are all great places to meet new people, primarily because you will be forced to see the same people over and over again in the class. You will automatically make friends with them if you have a common interest and are forced to see each other again.

Tips:

* In the beginning, never turn down an invitation from someone, even if it’s something you wouldn’t normally do.

* Email your new friends with fun things to do instead of always asking what their plans are. If they have a better plan you can drop yours and join them. This will help establish you as someone who is contributing value instead of just taking it (people want this in a friend).

* Don’t let little things in life upset you or be a negative person. People don’t want to be around someone like that! 

1.________ can give you an excuse to start new connections.

A．Taking pictures of others

B．Eating by yourself in public

A．approach others to show conscious friendliness

B．sit on your own in public places

C．invite others to your apartment to eat together

D．start a conversation with those who have friends aside

3.Which of the following pieces of advice is a tip from the text?

A．Try to be outgoing and talkative instead of being shy.

B．Never turn down an invitation from your friends.

C．Offer suggestions on how to spend time together.

4.By writing the text, the author intends to tell us ________.

A．why you should change when you move to a new city

B．how you can make new friends in a new city

C．why you should make new friends in a new city

D．how you can keep in touch with strangers
