Lucy skeleton (骨骼) unearthed in Ethiopia in 1974 - will go on an exhibition tour abroad for the first time
in the United States, officials said Tuesday.
Even the Ethiopian public has only seen Lucy twice. The Lucy on exhibition at the Ethiopian National
Museum in the capital, Addis Ababa, is a replica while the real remains are usually locked in a secret
storeroom. A team from the Museum of National Science in Houston, Texas, spent four years discussing with the Ethiopians for the U.S. tour, which will start in Houston next September.
"Ethiopia"s rich culture of both the past and today, is one of the best kept secrets in the world," said
Joel Bartsch, director of the Houston museum.
The six-year tour will also go to Washington, New York, Denver and Chicago. Officials said six
other U.S. cities may be on the tour. But they said plans had not been worked out.
Travelling with Lucy will be 190 other fossils.

Mothers, doctors and nurse alike have no idea of where a baby"s blood sugar level lies. All we know is
that a low level is harmful to brain development and makes a baby easily annoyed. In this state, the baby is difficult to calm down and sleep is impossible. The baby asks for attention by crying and searching for food with its mouth.
It is not just unkind but also dangerous to say a four-hourly feeding schedule will make a baby satisfied. The first of
the experts to advocate a strict clock-watching schedule was Dr Frederic Truby King, who was against
feeding in the
night. I"ve never heard anything so ridiculous. Baby feeding shouldn"t follow a timetable set by the mum.
What is important is feeding a baby in the best way, though it may cause some inconvenience in the first
few weeks.
Well, at last we have copper-bottomed research that supports demand feeding and points out the weaknesses of strictly timed feeding. The research finds out that babies who are fed on demand do better at
school at age 5, 7, 11 and 14, than babies fed according to the clock. By the age of 8, their IQ(智商)
scores are four to five percent higher than babies fed by a rigid timetable. This Research comes from
Oxford and Essex University using a sample(样本)of 10,419 children born in the early 1990s, taking
account of parental education, family income, a child"s sex and age, the mother"s health and feeling style.
These results don"t surprise me. Feeding according to schedule runs the risk of harming the rapidly growing brain by taking no account of sinking blood sugar levels.
I hope this research will put an end to advocating strictly timed baby feeding practices.

is available. First aid may save a life or improve certain important signs including pulse, temperature, an
unobstructed (未堵塞的) airway and breathing. In minor emergencies, first aid may prevent a victim"s
condition from worsening and provide relief from pain. First aid must be done as quickly as possible. In
the case of the badly injured, a few minutes car make the difference between complete recovery and loss
of life.
First-aid measures depend upon a victim"s needs and the provider"s level of knowledge and skill.
Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury,for example,can lead to lifelong disabilify.
Despite the variety of possible injuries, several suggestions should be followed if first aid applies to all
emergencies. The first step is to call for professional medical help. The victim, if sensible, should be
reassured that medical aid has been requested, and asked for permission to provide any first aid. Next,
assess (评估) the scene, asking other people or the injured person"s family or friends about details of the
injury or illness, any care that may have already been given, and preexisting conditions such as high blood
pressure and heart trouble. The victim"s medical card should be checked that describes special medical
conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move
the victim.
First aid requires rapid assessment of victims to determine whether life-threatening conditions exist.
One method to assess a victim"s condition is known as the ABC, which stands for:
A-Airway: ls it open and unobstructed?
B-Breathing: Is the person breathing? Look, listen, and feel for breathing.
C-Circulation (循环) : Is there a pulse? Is the person bleeding badly? Check skin color and
temperature for additional indications of circulation problems.
B. spend a few minutes making the difference between recovery and death
C. know what to do and what not to do according to the condition of the victim
D. make it clear what illness the victim has had
B. Checking whether the victim is bleeding.
C. Telephoning a hospital at once.
D. Waiting for medical treatment before giving first aid.
B. signs
C. instruments
D. treatments
B. the history and skills of first aid
C. some knowledge to help anyone who may be injured in an accident
D. that first aid is dangerous to those who do not know how to do it
empty space. But,with the number of flights increasing each year,this emptiness no longer exists.
Researchers in the world of aviation(航空) are worried about the increasing pressure on pilots and
ground controllers. And increasing collisions ,occurring at or near an airport,have called attention to the
need for more aids(辅助设备) to aviation control.
People who travel the skies are not certain about air safety. A great deal of money is spent on new
and bigger aircraft and airports to deal with the vast increase in passengers travelling by air. Only a small
percentage of this money is spent on navigation(导航) and other aids. Actually,suitable electronic
equipment has long existed,and many companies market safety aids designed to make it safer for aircraft
to take off,fly any distance,and land,whatever the weather.
Yet,there are two problems to be solved. The first is to get govemments,airlines and airport officials to
agree to basic levels of safety aids. The second problem is to find a way of meeting these basic
requirements.
But no matter how well the equipment works,operators of the equipment still play an important role.
Communications between pilots and ground controllers are extremely important to air safety. It is worth
pointing out that the mishearing or misunderstanding of instructions in English and the use of another
language,in an intemational conversation,has led to two recent aircraft accidents. A new type of
instrument(仪器) called FLIGHTWATCH would help pilots prevent airport collisions. It would be
particularly helpful near airports.
B. there is no empty space for aids to aviation control
C. piloting and controlling planes is getting more difficult
D. the pressure on the ground becomes greater
B. money spent on electronic equipment is far from enough
C. suitable electronic equipment hasn"t been invented yet
D. it is dangerous for planes to take off or land
B. misunderstandings between pilots and ground controllers
C. quarrels among passengers
D. breakdowns of new types of instrument
People from East Asia tend to have more difficulty than those from Europe in distinguishing facial
expressions-and a new report published online in Current Biology explains why.
Rachael Jack,University of Glasgow researcher,said that rather than scanning evenly (均匀的)
across a face asWestemers do,Eastemers fix their attention on the eyes.
"We show that Eastemers and Westemers look at different face features to read facial expressions,
" Jack said." Westemers look at the eyes and the mouth in equal measure.whereas Easterners favor the
eyes and neglect(忽略) the mouth. "
According to Jack and her colleagues,the discovery shows that human communication of emotion is
more complex than previously believed. As a result,facial expressions that had been considered
universally recognizable cannot be used to reliably convey emotion in cross-cultural situations.
The researchers studied cultural differences in the recognition of facial expressions by recording the
eye movements of 13 Westem Caucasian and 13 East Asian people while they observed pictures of
expressive faces and put them into categories: happy,sad,surprised,fearful,disgusted,angry,or neutral.
They compared how accurately participants read those facial expressions using their particular eye
movement strategies.
It turned out that Eastemers focused much greater attention on the eyes and made significantly more
errors than Westerners did. "The cultural difference in eye movements that they show is probably a
reflection of cultural difference in facial expressions,"Jack said." Our data suggest that whereas
Westemers use the whole face to convey emotion, Eastemers use the eyes more and mouth less."
In short,the data show that facial expressions are not universal signals of human emotion. From
here on,examining how cultural factors have diversified these basic social skills will help our understanding of human emotion. Otherwise, when it comes to communicating emotions across cultures, Eastemers and Westemers will find themselves lost in trans- lation.

E. Speak slowly and pause.
F. Drop unnecessary words
Speaking to a group can be difficult, but listening to a bad speech is truly a tiresome task-especially
when the speaker is confusing. Don"t want to confuse your audience? Follow these suggestions:
1.
When it comes to understanding new information, the human brain needs a little time. First, we hear the words; then, we compare the new information to what we already know. If the two are different, we need to pause and think. But abreathless speaker never stops to let us think about what he or she is saying and
risks confusing us. Slow it
2.
Sometimes we all start a sentence one way and then switch directions, which is very difficult to follow. When you the audience confuse your listeners with opposing information, you leave the audience
wondering what part of the information is right and what part they should remember. Instead of relying and keeping correcting yourself, work to get the facts clear and straight.
3.
Jumpng from point to point as it comes to your mind puts the onus (责任)on your listeners to make up
for your lack of organisation. And it"s confusing for them to listen, reorganise, and figure out what you"re
saying all at once. But going smoothly from one point to the next helps them understand information more
easily. You can arrange things from beginning to end, small to large, top to bottom or by some other order. Just be sure to organise.
4.
Repeated use of um, ah, like, you know and some other useless noises can drive an audience crazy. It makes the speaker sound uncertain and unprepared, and it can leave listeners so annoyed that they can"t
pay attention. Recently I attended a speech that was marked by so many ums that audience members were rolling their eyes. Was anybody grasping the intended message? Um, probably not.
5.
Many speakers finish up their speeches with question-and-answer (Q & A) sessions, but some let the Q & A go on without a clear end. The audience is often left confused about whether the meeting is over
and when they can get up and leave. Do your listeners a favour by setting a time limit on questions, and
close your speech with a specific signal-even if it"s something simple like, "If you have any more questions, you know where to reach me."
Or even more to the point, conclude your speech with "Thanks for your time. "
