The United Nations Environment Program is calling for urgent action to reduce growing risks from chemicals. Better management of chemicals could save millions of lives and billions of dollars. As estimated, 143,000 chemicals are now produced. Yet the report says only a small number of these chemicals have been studied for their effects on human health and the environment. It says death and disability rates are high from the unsafe use of chemical products.

Sylvie Lemmet, director of the UNEP, says poor management of chemicals has a high economic cost. For example, she says the cost is higher than the amount of overseas development aid, or ODA, for health care in sub-Saharan Africa.

She says, “If you look at the estimated cost of poisoning from pesticide (杀虫剂) in sub-Saharan Africa, only the injury and the loss of working time is estimated to be 6.3 billion US dollars in 2009. This is higher than the total ODA that is going to the health part in the same area.”

The UNEP estimates that chemical sales worldwide will increase by around three percent a year until 2050. Chemical production is moving quickly from developed to developing countries. By 2020, chemical production is expected to increase by 40 percent in Africa and the Middle East and 33 percent in Latin America. One of its biggest concerns is pollution of rivers and lakes by pesticide and fertilizer. Other major concerns are heavy metal pollution from the production of cement (水泥) and textiles (纺织品), and dioxin pollution from mining.

The UN report urges the chemical industry and governments to work together to develop safety policies. It says preventing harm costs less than fixing it.

1.The purpose of Paragraph 3 is mainly to indicate that ______.

A.chemicals have a high production cost

B.Africa needs more development aid

C.the use of pesticide causes a great loss

D.the estimated cost of poisoning from pesticide is incorrect

2.Which of the following is NOT a source of danger according to the text?

A.Pesticide. B.Fertilizer.

C.Heavy metals. D.Minerals.

3.According to the text, what is the main reason for the risks from chemicals?

A.The mass production of cement and textiles.

B.Lack of research funds on chemicals.

C.Poor management of chemicals.

D.Contradictions between chemical producers and governments.

4.What would be the best title for the text?

A.The truth in Sylvie Lemmet’s comments

B.A UN warning about chemical dangers

C.The unpredictable future of chemical industry

D.Preventing is much better than fixing

The United States Department of Agriculture has a program called Wildlife Services. Its job is to help protect agricultural and other resources. Often that means helping farmers deal with unwelcome visitors. This organization has experts from different fields and it has set up thousands of inquiry centers all over the country where farmer can explain their difficulty and get practical help.

One example from Wildlife Services of its work involved a farmer in Washington State in the Pacific Northwest. Several years ago, thousands of Canada geese landed on his fields. The geese began to eat his carrot crop. Biologists from the program suggested that the farmer use noise-making devices and other measures to scare the large birds away. These efforts succeeded, which made the farmer quite happy. Wildlife Services also has a livestock protection program. The program just offers suggestions to keep those unwelcome visitors away instead of killing them. The Wildlife Services program is part of the Animal and Plant Health Inspection Service, or APHIS. APHIS offers some suggestions of ways to keep away predators. For example, try to keep food and water safe from wildlife. Fences may help keep out wolves, especially if the fences are at least two meters high.

Experts suggest providing secure shelter for chickens, sheep and other animals that could be attacked. They also suggest using lights above places where these animals are kept. And they advise people who see wolves to chase them away by shouting, making loud noises or throwing rocks. And to protect livestock, consider using guard animals such as dogs and donkeys, which are very effective.

For home gardeners, a two-meter fence might help keep out deer. To keep out rabbits, a wire fence has to be only about a half-meter high. It should extend fifteen centimeters underground to keep rabbits from digging under it. If snakes are a problem, remove dead trees and cut high grass to destroy their hiding places. Due to its effective work, ever since the Wildlife Services was started, it has been well received by farmers all over the States and neighboring countries such as Canada and Mexico.

1.What does wildlife Services aim to help farmer handle?

A.Animals that attack farmers.

B.People who pollute the farmland.

C.People who don't care about wildlife.

D.Animals that do harm to crops or livestock.

2.It can be inferred from Paragraph 2 that ______.

A.the cabbage crop was eaten up by Canada geese

B.the farmer didn't have a gun to kill those Canada geese

C.Wildlife Services involves some biologists in its group

D.the farmers like to eat Canada geese very much

3.What is mainly discussed in Paragraph 3?

A.Ways to protect livestock.

B.Ways to deal with wolves.

C.How to protect crops.

D.How to hunt wildlife.

4.Why should the bottom of the fence extend about 15 centimeters into the ground?

A.Wolves can climb over it easily.

B.The strong wind might blow it away.

C.Snakes can cross it from under the ground.

D.Rabbits may enter by digging holes under it.

5.Where does the passage probably come from?

A.A tourist brochure.

B.A science magazine.

C.An entertainment program.

What is a fair wage? 　 1.　　　 These are some of the questions the United Nations International Labour Organisation(ILO) has recently investigated.

With a global population of over seven billion, is it actually possible to measure an average amount?_ 2._ Using the total wage bill from over seventy countries, they have multiplied the amounts by the number of earners in each country. The economists then tallied up the results and divided them by the total number across the world The result was a world average wage equivalent to $1,490 a month. _3._

This figure might seem very high because they calculated the amount using purchasing power parity dollars, which takes into account the fact that it is cheaper to live in some countries than others. _4._

Calculating an average sum like this might not be a completely fair representation, but these figures do help us to understand how the world is developing, both economically, in the quality of life people are experiencing and their standard of living.

But the result shows that the average wage is still relatively low and there remains a huge difference in levels of affluence around the world. _5._ Is this fair? For many, pay equality still seems very far out of reach.

A. The ILO has now tried to work out the sums.

B. The ILO used statistics from over 70 different countries

C. Why aren't more people in the world offered pay equality?

D. That is approximately $75 a day for a 20-day working month.

E. Some people live on just two dollars a day, while others are earning more than a million dollars a year.

F. When someone works for themselves, what are they called?

G. The data also did not include the huge number of people who appear in poverty statistics or who are self-employed.

Football--called soccer in the United States--is probably the most popular sport in the world today, It has been popular for a long time. But many years ago each country had different rules for its own football game.

In 1863 a group of people met in England to change this. They wrote a set of rules for all countries to follow. They also planned for soccer teams from different countries to play against each other. The idea worked. These rules are the same today, more than 100 years later.  Now teams from all the world compete in the famous World Cup. The cup is a series of games which is held every four years. Team from many countries plays to see which is the best. Soccer is so popular today that it is not unusual for 600 million people to watch a World Cup match on television.

How did the World Cup start? The soccer team from Uruguay won the Olympic championship in soccer in 1924 and 1928. That country decided to have the first World Cup games in Montevideo in 1930, These first games were not very successful. Only thirteen teams arrived to play and eight of them were from South America.

It didn't seem like a world championship. The team from Uruguay won the Cup that first year.
