People all over the world today are beginning to hear and learn more and more about the pr

oblem of pollution. Pollution is caused either by man's release of completely new and often artificial (人造) substances into the environment, or by releasing greatly increased amounts of a natural substance (物质), such as oil from oil tankers into the sea.

Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments Would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed off drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metal and paper. Advertising has helped this process by persuading many of us no only to buy thing we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyone can help to solve by curing out unnecessary buying, excess use and careless disposal (处理) of the products we use in our daily lives.

The main cause of pollution is ______.

A.the release of artificial or natural substances into the environment

B.the production of new industrial goods

C.increased amounts of a natural substance

D.our ever-increasing population

The first ancient Olympics were held in 776 B.C. The games got their name from Olympia, the Greek city where they took place. Like the summer Olympics of today, the ancient Olympics were held every four years.

Thousands of people from all over the Greek world came to watch. The main stadium held about 45,000 people. "We have accounts of visitors and pilgrims setting up tents all around the site", Lisa Cerrato of Tufts University said.

During the first Olympics, there was only one competition—a 200-meter race. But over time the games grew to include wrestling, chariot racing, boxing, and other sports. Women were not allowed to compete, but they had their own separate games.

"The ancient athlete became celebrities(名人), just like today. They often lived the rest of their lives being treated to free dinners", Cerrato said. "City-states even tried to steal away each other's athletes by offering them various awards".

The ancient Olympics existed until A.D. 393. But the modern Olympics are still going strong.

Where did the ancient Greeks hold their first Olympics?()

A.In Athens.

B.In Olympics.

C.In a town.

D.In a state.

Red Nose Day (RND) is a well-known event in the UK.The aim of the day is to raise money for Comic Relief.This is a charity that helps people in need in Africa and in the UK.

Comic Relief was started in 1985 by Richard Curtis.He wrote the famous films “Four Weddings and a Funeral” and “Notting Hill”.Richard started Comic Relief in response to the severe famine in Ethiopia.It’s called Red Nose Day as on this day many people buy a plastic red nose to wear! The money made from selling red noses goes to the charity.

Red Nose Day takes place every two years in the spring.It is now so well established that many people consider it to be an unofficial national holiday.

The slogan for the last RND was “Do Something Funny for Money.” The money that was collected was used to help fund projects in such areas as education and mental health.Money-raising events take place on this day all over the country and many schools participate.People also donate money by post, inbanks, by phone using a credit card and online.

In the evening of Red Nose Day a telethon takes place on the BBC TV channels.This is like a television marathon (马拉松)that shows some of the events of the day and reports how the money raised will be spent.People also upload videos of local charity events onto the Internet.

第11题

We all know that DNA has the ability to identify individuals but, because it is inherited,
there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population. Molecular Genealogy (宗谱学) can use this unique identification provided by the genetic markers to link people together into family trees. Pedigrees (家谱) based on such genetic markers can mean a break-through for family trees where information is incomplete or missing due to adoption, illegitimacy or lack of records. There are many communities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom many records were never kept in the first place.

The main objective of the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples from individuals all over the world. These individuals will have provided a pedigree chart of at least four generations and a small blood sample. Once the database has enough samples to represent the world genetic make-up, it will eventually help in solving many issues regarding genealogies that could not be done by relying only on traditional written records. Theoretically, any individual will someday be able to trace his or her family origins through this database.

In the meantime, as the database is being created, molecular genealogy can already verify possible or suspected relationships between individuals. "For example, if two men sharing the same last name believe that they are related, but no written record proves this relationship, we can verify this possibility by collecting a sample of DNA from both and looking for common markers (in this case we can look primarily at the Y chromosome (染色体)," explains George Green, a member of the BYU Molecular Genealogy research team.

People in a large area may possess the same DNA thread because______.

A.DNA is characteristic of a region

B.they are beyond doubt of common ancestry

C.DNA strand has the ability to identify individuals

D.their unique identification can be provided via DNA
