quake killed more than 900 people in Chile. And few weeks later, a 6.0 magnitude quake struck rural
eastern Turkey, killing at least 57 people.
The earthquakes kept coming hard and fast. 1 It"s not. The problem is what"s happening above
ground, not underground, experts say.
2 They"re rapidly putting up buildings that can"t stand up to earth quakes, scientists believer.
And news reports and better earthqua
ke monitoring make it seem as if earth quakes are increasing all thetime.
On average, there are 134 earthquakes a year that have a magnitude between 6.0 and 6.9. So far this
year there have been 40 earthquakes-more than in most years for that time period. But that"s because the
8.8 quake in Chile caused a large number of strong aftershocks.
Also, it"s not the number of quakes, but their destructive effects that gain attention. The death is largely
due to building standards, 3 Paul Earle, a US seismologist, called for better building standards in the
world"s big cities.
Of the 130 cities worldwide with populations of more than I million, more than half are likely to be
hit by earthquakes. 4 "If you have a problem feeding yourself, you"re not really going to worry about
earthquakes,
" said Paul.The earthquakes made everyone start to think 5 "People are paying attention to the violent planet
we"re always lived on. Come back an another six moths if there has been no earthquakes, most people
will have forgotten it again," said US disaster researcher Dennis Mileti.
B．More people are moving into big cities.
C．Earthquakes don"t kill people, buildings do.
D．There have been more deaths overt the past decade from earthquakes.
E．Many people began to wonder if something terrible is happening underground.
F．While it seems as if the are more earthquakes occurring, there really aren"t.
G．But developing nations with growing populations don"t pay attention to earthquake preparedness.

Ace told the McClatchy News Service that at least 1,000 places should be chosen to spray water. The water would be sprayed between 20 and 200 feet into the air. Thousands of tons of seawater would be
sprayed for years at a time.
The 1,000 sites would be picked after more studies. They would be mostly in the Northern
Hemisphere. Ace says he would avoid tropical (热带的) areas of the globe. He says water turns to rain
too quickly in these areas for his plan to work.
The wate
r would be changed into vapor. That process require
s heat. The water vapor would rise above the Earth. The vapor would form clouds. The clouds would help in several ways. They would coo
l the Earth by reflecting sunlight. They would later turn into rains. The rains would provide another way of cooling the Earth.
Ace’s plan has gotten some support from a limited scientific study. Kenneth Caldeira is a climate
scientist. He works at the Carnegie Institution’s Department of Global Ecology at Stanford University in
California. Caldeira tested some of Ace’s figures on a computer program. The computer model is used by top
scientists to study global climate change. The model showed that the plan might work."More tests are planned in 2009. Ideas like Ace’s should be considered carefully and with an open
mind," Caldeira said. “Every brilliant invention in the history of technology looked a little bit mad when first put forward.”
1. What’s the purpose of Ace’s plan?
A. To reduce air polluti
on. B. To make summer cooler.
C. To offer dry areas more rain.
D. To solve the problem of global warming.
2. According to Ace’s plan, ________.
A. planes would be used to spray water
B. it would be best to spray water on rainy days
C. seawater would be sprayed high into the sky
D. 1,000 sites in the Southern Hemisphere would be chosen
3. Why wouldn’t Ace spray water in tropical areas?
A. Water is changed i
nto vapor too quickly. B. Water turns to rain too quickly.
C. It is hard for vapor to form clouds.
D. It is bad for local plants to have too much rain.
4. It seems that Caldeira _________.
A. takes Ace’s plan seriously
B. thinks Ace’s idea too
crazyC. doesn’t believe the computer’s result
D. agrees to carry out Ace’s plan right now
5. According to the passage, Ace can be best described as __________.
A. mad
B. creative
C. mysterious
D. optimistic
American culture the smile is in general an expression of pleasure. Yet it also has other uses. A woman’s
smile at a police officer does not carry the same meaning as the smile she gives to a young child. A smile
may show love or politeness. It can also hide true feelings. It often causes confusion (困惑) across cultures. For example, many people in Russia consider smiling at strangers in public to be unusual and even improper. Yet many Americans smile freely at strangers in public places (although this is less common in big
cities). Some Russians believe that Americans smile in the wrong places; some Americans believe that Russians don’t smile enough. In Southeast Asian cultures, a smile is frequently used to cover painful feelings.
Vietnamese people may tell a sad story but end the story with a smile.
Our faces show emotions (情感), but we should not attempt to “read” people from another culture as we would “read” someone from our own culture. The fact that members of one culture do not express their emotions as openly as do members of another does not mean that they do not experience emotions.
Rather, there are cultural differences in the amount of facial expressiveness permitted. For example, in
"public and in formal situations many Japanese do not show their emotions as freely as Americans do.
When with friends, Japanese and Americans seem to show their emotions similarly.
It is difficult to generalize about Americans and facial expressiveness because of personal and cultural
backgrounds in the United States. People from certain cultural backgrounds in the United States seem to
be more facially expressive than others. The key is to try not to judge people whose ways of showing
emotion are different. If we judge according to our own cultural habits, we may make the mistake of
“reading” the other person incorrectly.
B. Politeness
C. Joy
D. Thankfulness
B. be used to hide true feelings
C. be used in the wrong places
D. show personal habits
B. Understand their cultural backgrounds
C. Find out about their past experience
D. Figure out what they will do next
B. Smiles and Relationships
C. Facial Expressiveness
D. Habits and Emotions

MASA AMES Center(美国宇航局) have already started the creation of a "Mars town" and many
others are in fact already experimenting with it. Of course, these experiments are done on Earth itself but
this "Mars town" has an environment practically like that of Mars.
The astronauts working in these towns wear their space suit and also do everything they would really
have to carry out if they ever go to Mars in the future.
But Mars would be like Earth, a temporary(临时的) place for humans. When the Sun starts
swallowing up(吞掉) the planets, Mars will disappear only hours after Earth. So Mars only seems to be
the ideal place to spread the human beings. It is also a good location to send humans if ev
er there is a disaster on Earth. By saying disaster, I mean asteroids(小行星) hitting and things like that.
If we humans do not want to disappear when Earth or Mars gets swallowed up, we will have to go
and live beyond the solar system. But are there any planets outside our solar system prepared to support
life? Astronomers" answer is:
"If Earth can support life, why can"t other planets do the same too? Astronomers have already discovered a Jupiter(木星)- like planet orbiting a Sun-like star, so why not an Earth-like planet orbiting a
Sun-like star?
To achieve this goal though, many other problems have to be taken into consideration. How do we
transform(改造) a dusty planet like Mars into one more or less like our Earth? How should we go on?
There is still a long way to go.
B. an experimental lab built on Earth.
C. a strange place on Mars .
D. a town existing in scientists" imagination
B. there may be an Earth-like planet outside the solar system
C. humans will move to the new-found Jupiter-like planet
D. there"s no need for humans to move beyond the solar system.
B. There would be more disasters like asteroids hitting.
C .It would disappear when Earth disappeared.
D. It would be too hot to live on.
B. getting close to
C. passing by quickly
D. going through
B. Living on Mars
C. The Future of Earth
D. Where to live in the Future
switch jobs and focus instead on sound, a new study has found.
The study, by researchers at the University of Montreal, involved 7 adults who could see and
12 adults who had lost their vision when they were children. Each participant sat in a room with
16 loudspeakers at different locations. The room was designed so that there were no echoes(回音).
During the experiment, the speakers irregularly produced sounds. Participants had to point to where
the sounds were coming from. Meanwhile, the researchers monitored blood flow in the brains of the
participants to see which brain structures were working during the task.
The results showed that five of the blind participants were very good at pointing to where sounds
were coming from. In these people, blood flow increased in the visual cortex(大脑皮层)-an area at
the back of the right side of the brain. This part of the brain is usually associated with vision.
The other seven blind participants showed no increase in activity in the visual cortex. These people
didn"t do very well at picking out where sounds were coming from. Now, the researchers are looking
at whether these people have gained an enhanced sense of touch instead of sound to replace their lost
vision.
The scientists say that their study shows how adaptable parts of the brain can be.
B. blind people have a better sense of sound
C. the sense of touch is better among blind people
D. blood flow in the brains of blind people is slower
B. to take down the time each sound lasted
C. to identify the direction the sound came from
D. to detect the number of the loudspeakers
B. look for the way of enhancing hearing ability
C. find which parts of the brain were functioning
D. expose the relationship between seeing and touching
B. People go blind because of the breakdown of their visual cortex.
C. Most blind people have a better sense of sound than normal people.
D. Human brains can adjust themselves after the loss of a certain function.
