How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the US.
For some parents, the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as danger. With good guides, some education, and a few precautions(预防 ), the wilds of the Internet can be safely navigated. “Kids have to be on-line. If we tell our kids they can’t be allowed to surf the Internet, we’re cutting them off from their future,” said an expert.
Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way would be to use what is known as a “content screener”. But this can’t be wholly reliable(可靠 ), and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing the Internet.
A few other tips:
—Do not put the PC in a child’s room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity.
—Ask your child what he or she has been doing and about any friends they make on-line.
―Tell your child not to give on-line strangers personal information, especially like address and phone number.
And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.
小题1:What is the best way to protect children from improper material?
A.To talk to the children and persuade them to tell right from wrong.

Global warming is causing more than 300,000 deaths and about $125 billion in economic losses each year, according to a report by the Global Humanitarian Forum, an organization led by Annan, the former United Nations secretary general.
The report, to be released Friday, analyzed data and existing studies of health, disaster, population and economic trends. It found that human-influenced climate change was raising the global death rates from illnesses including malnutrition (营养不良) and heat-related health problems.
But even before its release, the report drew criticism from some experts on climate and risk, who questioned its methods and conclusions.
Along with the deaths, the report said that the lives of 325 million people, primarily in poor countries, were being seriously affected by climate change. It projected that the number would double by 2030.
Roger Pielke Jr., a political scientist at the University of Colorado, Boulder, who studies disaster trends, said the Forum’s report was “a methodological embarrassment” because there was no way to distinguish deaths or economic losses related to human-driven global warming amid the much larger losses resulting from the growth in populations and economic development in vulnerable (易受伤害的) regions. Dr. Pielke said that “climate change is an important problem requiring our utmost (极度的) attention.” But the report, he said, “will harm the cause for action on both climate change and disasters because it is so deeply flawed (有瑕疵的).”
However, Soren Andreasen, a social scientist at Dalberg Global Development Partners who supervised the writing of the report, defended it, saying that it was clear that the numbers were rough estimates. He said the report was aimed at world leaders, who will meet in Copenhagen in December to negotiate a new international climate treaty.
In a press release describing the report, Mr. Annan stressed the need for the negotiations to focus on increasing the flow of money from rich to poor regions to help reduce their vulnerability(弱点) to climate hazards(危害)while still curbing (限制) the emissions of the heat-trapping gases. More than 90% of the human and economic losses from climate change are occurring in poor countries, according to the report.
小题1:What is the finding of the Global Humanitarian Forum?
A.Global temperatures affect the rate of economic development.
B.Rates of death from illnesses have risen due to global warming.
C.Malnutrition has caused serious health problems in poor countries.
D.Economic trends have to do with population and natural disasters.
小题2:  What do we learn about the Forum’s report from the passage?
A.It was challenged by some climate and risk experts.
B.It aroused a lot of interest in the scientific circles.
C.It was warmly received by environmentalists.
D.It caused a big stir in developing countries.
小题3: What does Dr. Pielke say about the Forum’s report?
A.Its statistics look embarrassing.
B.It is invalid in terms of methodology.
C.It deserves our closest attention.
D.Its conclusion is purposely exaggerated.
小题4:  What is Soren Andreasen’s view of the report?
A.Its conclusions are based on carefully collected data.
B.It is vulnerable to criticism if the statistics are closely examined.
C.It will give rise to heated discussions at the Copenhagen conference.
D.Its rough estimates are meant to draw the attention of world leaders.
小题5:  What does Kofi Annan say should be the focus of the Copenhagen conference?
A.How rich and poor regions can share responsibility in curbing global warming.
B.How human and economic losses from climate change can be reduced.
C.How emissions of heat-trapping gases can be reduced on a global scale.
D.How rich countries can better help poor regions reduce climate hazards.

It doesn’t matter if you have one friend or 20, because there are only a few people in this world that can make you truly happy. For me, my family and my three best girlfriends mean everything to me.
Some days I didn’t want to go to school because I felt so disappointed in myself but I don’t regret a thing. It makes you stronger as a person, and if you are able to mend your friendships like I have done, then you can do anything.

If a friend is a piece of work, then he or she has never been a friend at all. A friend is the biggest gift to you.”
Everyone is going to make mistakes but please don’t push them away, especially if it’s someone you really care about. I know when I make mistake I beat myself up about it. I just wish someone would have reached out a hand to help me back up on my feet like my best friend did. If someone is new or doesn’t have a friend, please reach out and befriend them because that small action could mean the world to them.

Morocco is located at the northwest of Africa and is bordered in the north by the strait of Gibraltar and the Mediterranean Sea. The Atlantic Ocean keeps the west and the north of the country more temperate(温和的). The country also offers the broadest plains some of which run along the Atlantic Ocean and the highest mountains in North Africa including the Atlas Mountains.
Starting with the symbol of Morocco, Marrakech is a beautiful city that has remained unspoiled by the volume of tourists that flock there each year. One of the finest monuments in Morocco is greatly benefited by this amount of tourism. Actually their high volume contributes in a positive way to preserve one of the greatest monuments of Morocco.
Fes is the third largest city in Morocco and is the capital of the Fes-Boulemane Region. It is separated into three parts, Fes el Bali more commonly known as the old walled city, now classified as a UNESCO World Heritage Site, Fes-Jdid and the Ville Nouvelle. Fes el Bali is believed to be the largest car-free urban area in the world. Fes is a splendid place to visit to heighten the senses with the colours, smells and sounds.
Casablanca is an enormous city which is near the capital of Morocco and a place where any European would feel at home. Casablanca was made famous by the movie and gives the impression of being a romantic place. Unfortunately like many other popular cities around the world, it is crowded, noisy, and polluted, a far cry from the romantic ideal of the film. Because it has the biggest port, Casablanca being the important city of Morocco, has everything that the tourists need.
Asilah is a city situated on the Atlantic Ocean and is one of the most stunning(出色的) old cities of Morocco. The city is set along the cliffs which make it beautifully presented and an ideal place to continue adding to its economy by the fishermen.

Everybody hates rats(老鼠). But in the earthquake capitals of the world—Japan, Los Angeles, Turkey—rats will soon be man’s new best friends.
What happens after an earthquake? We send in rescue dogs. Why? Because they can smell people. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal(信号). This is sent to a small radio on its back and then the rescuers follow the radio signals. When rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, “Robots’ noses don’t work well when there are other smells around. Rats are good at that. ” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity!
The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn’t get to, and a rat would get out if it wasn’t safe. ” Perhaps for the first time in history, people will be happy to see a rat in a building, but only after an earthquake, of course.
小题1: In the world earthquake capitals, rats will become man’s best friends because they can ______.
A.take the place of man’s rescue jobs
B.find the position of people alive who are trapped in buildings
C.serve as food for people alive who are trapped in buildings
D.get into small spaces
小题2:From the third paragraph we know the rescuers can judge a person is alive by ______.
A.the noise made by the rat
B.the rat’s unusual behavior
C.the signal sent by the radio on the rat’s back
D.the smell given off by the person
小题3:In doing rescue jobs, ______.
A.rats smell better than dogs
B.dogs don’t need to be trained to smell people
C.robots’ sense of smell can be affected by other smells around
D.rats can see in the dark and they are smaller than robots
小题4:Rats have all the following advantages EXCEPT that ______.
A.they are more fantastic than other animals
B.they are less expensive to train than dogs
C.they don’t need electricity
D.they are small and can get into small places

In old times,  man considered lightning to be one of the great mysteries(神秘事物)of nature.  In fact a single flash of lightning 1. 6 kilometers long has enough electricity to light one million lamps.    
The American scientist, Benjamin Franklin, was the first to suggest that lightning is in fact electricity formed between the earth and clouds high above. It happened in 1752. In the same year, he also built the first lightning rod(避雷针)to protect buildings from being struck by lightnings.    
Modern science has discovered that lightning is very strong and powerful. A lightning between a cloud and the earth may be as long as 13 kilometers, and travels at a speed of 30 million meters per second.  Scientists have the opinion that there are about 2, 000 million flashes of lightning per year. In the United States alone, it kills almost one person per day.     The safest place to be in during an electrical storm is a closed car. Outside, one should go close to low ground for cover and not stop under a tree. Also one should stay out of water and away from metal fences. Inside a house people should keep away from open doorways and windows and not touch wires or metal things.
