Last Sep.11 was an important day too. After unknown gunmen attacked aid workers from the Nobel Prize-winning Medecins sans Frontieres at a roadblock on that day , most of the international aid groups helping Darfur’s 6 million people stopped using the roads . On Dec.18 , unknown gunmen attacked the southern town of Gereida. More than 70 aid workers then pulled out of the refugee(难民) camp there—Darfur’s largest, with 130,000 people —leaving only 10 Red Cross employees behind. Yet at the time no one said what had really caused the sudden pullbacks.

Damaging has become surprisingly common in Darfur, where 200,000 Africans have been killed and a third of the population have been sent fleeing into camps in three years of war. But the attacks on international aid workers suggested a dramatic and dangerous start—to attack on purpose those helping to keep Darfur’s millions of refugee alive. A dozen people from foreign NGOs (non－governmental organizations) have been killed in just the past six months , more than previous years. There are about 14,000 aid workers in Darfur now , the majority of them Sudanese, working for foreign NGOs and U.N. agencies and delivering $1 billion a year in aid . Just a few more terrible attacks could throw that into jeopardy. Last week 14 U.N. offices working in Darfur made a clear warning that “the humanitarian (人道主义) organization cannot possibly make certain the survival of the population Darfur if aid workers don’t feel safe. ”

A Good Teacher is a Strict Teacher

    One of the most important parts in the healthy development of a

child is played by education. But the way in which education is

understood has changed completely, as we must not forget that

the severe and unfeeling way of bringing up a child in the past

was primarily based on cruel grounding（基础）and strict

rules that were supposed to create accomplished individuals, the typical gentlemen. Nowdays,

society is much more open-minded and it does not put a great value on being strict, although this

doesn’t mean that opinions regarding this subject do not differ.

    On the one hand, there are also people who believe that there has got to be a bound between

teacher and student if any satisfying results are awaited. Luckily for us, more and more teachers are

understanding this fact and are doing their best to get over the strict rules and get in touch with us.

    My opinion is that only by having a friendly attitude and accepting other opinions, especially

those of your pupils, you are truly able to do your job at high standards. However, this does not

mean that a teacher shouldn’t be a bit more rough when he feels that things are getting out of hand.

All in all, I must say that a good teacher is the teacher that has the ability to be kind and strict at the

same time, thus achieving to gain his students respect and interest.

The aim of education in the past was to      .

       A．create perfect persons      B．create open-minded persons

       C．bring up a child              D．build a cruel grounding

According to the passage, the narrow-minded people think      .

       A．a pupil is always interested in what he is learning

       B．a pupil himself will improve his studies

       C．children should be made to study

       D．children don’t like a rough hand

The underlined word “job” in the last paragraph can be replaced by      .

       A．controlling       B．teaching    C．learning    D．punishing

The author thinks a good teacher should be     .

       A．kind and strict         B．skilled and clever

       C．rough and cruel              D．friendly and practical

It can be inferred from the passage that       .

       A．society is much more open-minded and being strict is out date

       B．as long as the teachers are strict with students, the students will certainly get good marks

       C．most people are in favor of strict teachers because they have strict grounding and strict rules

       D．if we expect students to develop in a healthy way, the good relationship between teachers and students is important

LONDON: What could possibly be wrong with planting trees? The benefits are obvious; they  firm the soil, soak up (摄取) extra water and take carbon dioxide (二氧化碳) our of the atmosphere.
However, it now turns out that planting trees could add to global warming.
Tree roots do a great job of keeping soil firmly on the ground and out of the wind’s power. The problem is that some of those dust clouds play an important part in soaking up carbon dioxide.
Huge dust storms blow out over the oceans from dry parts of North Africa and central Asia. Tons of dust are lifted and left as a thin film over the ocean surface. The dust fuels oceanic life.
Dust from China is carried east and left in the Pacific Ocean. If a tree-planting programme there is successful and the dust supply reduced, the net result may be that less carbon dioxide gets locked away in the ocean.
Andy Ridgwell, an environmental scientist from the University of East Anglia, has spent the past few years studying dust and says his work “shows clearly that the complexity of the system and the importance of not tinkering(粗劣地修补) with it without understanding the results. For this reason the need is to focus(集中) on cutting carbon dioxide giving off rather than monkeying (瞎弄) about with the land surface.”
An American scientist, Robert Jackson, has shown that when native grassland areas are invaded(侵入) by trees, carbon is lost from the soil. “We are studying why the soil carbon disappears, but one theory is that trees do a lot more of their growing above ground compared to grasses, so less carbon goes directly into the soil from trees, ” says Jackson.
In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed(超过) by the loss of carbon from the soil below ground. Countries that plan to combat global warming by planting trees may have to think again.
Solutions to environmental problems are often more complex than they first appear, and understanding the Earth’s climate is a very great challenge.
63．People usually hold the opinion that       .
A．huge dust storms can destroy carbon dioxide
B．huge dust storms can destroy the oceans on the earth
C．huge dust storms can’t do anything beneficial for man
D．planting trees is the only way to control huge dust storms
64．Andy Ridgwell, the environmental scientist, believes that       .
A．dust plays a more important part than trees
B．trees should’t have been planted in dry places
C．carbon dioxide is harmful to everything on the earth
D．environmental problems are more complex than expected
65．Robert Jackson’s experiment proves that         .
A．grassland areas should be covered by forests
B．trees hold more carbon than grasses
C．carbon can turn grass into dust
D．less carbon can make trees grow faster
66．The underlined word “combat” in the last paragraph means      .
A．learn about      B．fight against     C．live with   D．give up

　　In the atmosphere,carbon dioxide actd rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from excaping.
　　According to a weather expert's prediction,the atmosphere will be 3 warmer in the year 2050 than it is today, if man continues to burn luels at the present rate. If this warming up took place,the ice caps in the poles would begin to melt,thus raising sea level several meters and severely flooding coastal cities.Also，the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球),psooicbly resulting in an alteration of earth's chief food growing zones.
　　In the past,concern about a man - made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic,which may be affected by a warming on the scale that will possibly take place in the next fifty years from on burning of fuels.
　　Satellite pictures showthat large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth.
　　However,most of the fuel is burnt in the northern hemisphere,where temperatures seem to be falling.Scientists conclude,therefore,that up to now natural influences on the weather have exceeded those caused by man.The question is:Which natural cause has most effect on the weather?
　　One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and cold spots(that is,the relatively less hot spots) on the sun. As the sun rotates(旋转),every 27.5 days,it presents hotter or colder faces to the earth,and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth's atmospheric pressure,and consequently on wind circulation.The sun is also variable over a long term:its heat output goes up and down in cycles,the latest trend being downward.
　　Scientists are now finding mutual relations between models of solar weather interactions and the actual climate over many thousands of years ,including the last Ice Age.The problem is that the models are predicting that the world should be entering a new Ice Age and it is not.
　　One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(不活动，惰性) of the earth's climate.If this is right,the warming effect of carbon dioxide might thus be serving as a useful counter balance to the sun's diminishing heat.
　　68.It can be concluded that a concentration of carbon dioxide in the atmosphere would ___.
　　　A.mean a warming - up im the Arctic
　　　B.raise the temperature of the earth's surface
　　　C.prevent the sun's rays from reaching the earth's surface
　　　D.account for great changes in the climate in the northern hemiphere
　　69.Although the fuel consumption is greater in the northern hemisphere,temperatures there seem to be falling.This is _______.
　　　A.mainly because the levels of carbon dioxide are rising
　　　B.partly due to variations in the output of solar energy
　　　C.possibly because the ice caps in the poles are melting
　　　D.exclusively due to the effect of the inertia of the earth's climate
　　70.On the basis of their models,scientists are of the opinion that ________.
　　　A.the climate of the world should be becoming cooler
　　　B.the new Ice Age will be delayed by the greenhouse effect
　　　C.the man - made warming effect helps to increase the solar effects
　　　D.it will take thousands of years for the inertia of the earth's climate to take effect
