In country after country, talk of nonsmokers' rights is in the air. This fresh voice is heard from Australia to Sweden. Its force is freeing clean air for nonsmokers -- and tightening the situation for smokers.
While a majority of countries have taken little or no action yet, some 30 nations have introduced legislative steps to control smoking abuse. Many laws have been introduced in other countries to help clear the air for nonsmokers, or to cut cigarette consumption.
In many developing nations, however, cigarette smoking is seen as a sign of economic progress -- and is even encouraged. While it appears that in developed countries the consumption of cigarettes has become stabilized, there are some indications that it is still rising at a steady pace in Latin America.
Despite progress in segregating (分开) nonsmokers and smokers, most countries see little change in the number of smokers. In fact, there is a jump in the number of girls and young women starting to smoke.
So far, any cooperation between tobacco interests and governments' campaigns against smoking has been in the area of tobacco advertising.
Restrictions on cigarette ads, plus health warnings on packages and bans on public smoking in certain places, are the most popular tools used by nations in support of nonsmokers or in curbing (抑制) smoking.
But world attention also is focusing on other steps which will:
-- Prevent pro-smoking scenes on TV and films.
-- Remove cigarette vending machines.
-- Make it illegal to sell or hand over tobacco products to minors.
-- Boost cigarette prices with higher tobacco taxes.
When you are traveling around the world, you will find that ______.
A．the topic of nonsmokers' rights is a hot issue for discussion
B．the expression "Don't puff on me" is posted everywhere
C．few countries pay attention to nonsmokers' rights
D．smokers are forced to give up smoking to keep the air clean

听力原文： Some students at the Open University left school 20 years ago. Others are younger but all must be at least 21 years old. This is one example of how the Open University is different from all other universities. Its students must either work full-time or be at home all day, for instance, mothers of families. They do not have to pass any examinations before they are accepted as students. This is why the university is called "open". The university was started in order to help a known group-people who missed having a university education when they were young.
The first name for the Open University was "The University of the Air". The idea was to teach "on the air", in other words, on radio and television. Most of the teaching is done like this. Radio and television have brought the classroom into people's homes. But this, on its own, is not enough for a university education. The Open University student also receives advice at one of 283 study centers in the country. 36 weeks of the year he has to send written work to a "tutor", the person who guides his studies. He must also spend 3 weeks every summer as a full-time student. Tutors and students meet and study together, as in other universities. At the end of the Open University's first year, the results were good. Three out of every 4 students passed their examinations. If they do this every year, they will finish their studies in four or five years.
(33)
A．Because the students have to pass all examinations before entering it.
B．Because there is no examination before they are accepted as students.
C．Because there is no gate.
D．Because it never closes.

The summer holidays are the best part of the year for most children.The weather is usually good, so that one can spend most of one’s time playing in the garden or, if one lives in the country, out in the woods and fields.Even if one lives in a big town, one can usually go to a park to play.
The best place for a summer holiday, however, is the seaside.Some children are lucky enough to live near the sea, but for the others who do not, a week or two at one of the big seaside towns is something which they will talk about for the whole of the following year.
In England, it is not only the rich who can take their children to the seaside; if a factory worker or a bus driver, a street cleaner or a waiter wants to take his wife and children to Southend or Margate, Blackpool or Clacton, he is usually quite able to do so.
Now, what is it that children like so much about the seaside？ I think it is the sand, sea and sun more than any other things.Of course, there are lots of new things to see, nice things to eat, and exciting things to do, but it is the feeling of sand under one’s feet, of salt water on one’s skin, and of the warm sun on one’s back that makes the seaside what it is.
1.Summer holidays start _________.
A.with July
B.as soon as the examinations are over
C.in mid-June
D.in August
2.After the examination, all pupils leave for home ________.
A.by train only
B.by air
C.by bike
D.by either train or car
3.The summer holiday lasts _______.

D.a little less than two months
4.July and August are the brightest months for most children, for they can _______.

Temperatures at Hudson Bay have risen by one half degree Fahrenheit every decade since 1950. Winter ice on the bay melts three weeks earlier than it did just 25 years ago, which means three fewer weeks of polar bear mealtime. Result: Polar bears are 10 percent thinner and produce 10 percent fewer cubs than they did 20 years ago. And though climatologists hotly debate the causes behind Earth's Arctic meltdown, "these changes are startling and unexpected,' says James McCarthy, co-leader of the United Nations Intergovernmental Panel on Climate Change.
The plight of polar bears is just the tip to the iceberg when it comes to mounting evidence of global warming. "There's definitely a stark contrast with the way things were at the start of the 20th century," says atmospheric scientist Leonard Druyan, of Columbia University. Recent data show the volume of Arctic sea ice has shrunk 20 percent since the 1950s; glaciers around the world are melting at rapidly increasing rates. Rivers and lakes in North America, Asia, and Europe now freeze about nine days later and thaw 10 days earlier than they did a century ago.
Most scientists believe the only effective strategy to halt global warming is to drastically reduce emissions of powerful air pollutants like carbon dioxide, which accounts for two-thirds of all greenhouse gases. In the last 150 years, the surging use of fossil fuels coal, oil, and natural gas -- has released 270 billion tons of carbon into the air in the form. of carbon dioxide. Fortunately, oceans, plants, and soils absorb more than half of all atmospheric carbon dioxide -- without them world temperatures might have already soared at an alarming rate.
By saying "Spring is usually prime food time for 1,200 polar bears"？ (Line I, Para. 1), the author means that ______.
A．spring is usually a good time for polar bears to carry out their mating rituals
B．the polar bears usually eat a lot in the spring
C．spring is generally a good time to hunt polar bears
D．polar bears usually hibernate in the spring
If you live in an apartment, know the ways you can use to get out. Show everyone in the family these routes. Stress the importance of using stairways or fire escapes, not elevators.
From most homes and the lower floors of apartment buildings, escape through windows is possible. Learn the best way of leaving by a window with the least chance of serious injury.
In a home fire, windows are often the only means of escape. The second floor window sill is usually not more than 13 feet from the ground. An average person, hanging by the fingertips, will have a drop of about six to the ground. Of course, it is after to jump a short way than to stay in a burning building. Rolling away from the building when you land.
Windows are also useful when you are waiting for help. Often you'll be able to stay in the room for several minutes if you keep the door closed and the windows open. Keep your head low in the window to be sure you get fresh air rather than smoke that may have leaked into the room.
On a second or third floor, the best windows for escape are those which open onto a roof or balcony. From the roof or balcony, a person can either drop to the ground or await rescuer. Dropping onto cement or pavement might end in injury. Bushes, soft earth, and grass can help to break a fall. A rope ladder should be considered when the drop is too great.
In a town where the fire department acts quickly, it may be best to wait for rescuer. Close the doors and wait by an open window for help. Shout for help. Be sure to close the door before opening a window. Otherwise, smoke and fire may be drawn into the room by the draft.
From most homes you can escape a fire through the ______.
A．attic
B．garage
C．windows
D．balcony
