The Dangers of Secondhand Smoke
Most people know that cigarette smoking is harmful to their health. Scientific research shows that it causes many kinds of diseases. 1. However, Edward Gilson has lung cancer, and he has never smoked cigarettes. He lives with his wife, Evelyn, who has smoked about a pack of cigarettes a day throughout their marriage. The Gilsons have been married for 35 years.
No one knows for sure why Mr. Gilson has lung cancer. However, doctors believe that secondhand smoke may cause lung cancer in people who do not smoke because nonsmokers often breathe in the smoke from other people’s cigarettes. _2. The US Environmental Protection Agency reports that about 53, 000 people die in the United States each year as a result of exposure to secondhand smoke.
The smoke that comes from a lit cigarette contains many different poisonous chemicals. In the past, scientists did not think that these chemicals could harm a nonsmoker’s health. 3. They discovered that even nonsmokers had unhealthy amounts of these toxic (有毒的) chemicals in their bodies. 4. For example, we cannot avoid secondhand smoke in restaurants, hotels and other public places. Even though many public places have nonsmoking areas, smoke flows in from the areas where smoking is permitted. It is even harder for children to avoid secondhand smoke. In the United States, nine million children under the age of five live in homes with at least one smoker.
Research shows that children who are exposed to secondhand smoke are sick more often than children who live in homes where no one smokes and that the children of smokers are more than twice as likely to develop lung cancer when they are adults as the children of nonsmokers. The risk is even higher for children who live in homes where both parents smoke.
5. As a result, they have passed laws which prohibit people from smoking in many public places.
A. Recently, though, scientists changed their opinion after they studied a large group of nonsmokers.
B. As a matter of fact, almost all of US breathe tobacco smoke at times, whether we realize it or not.
C. In fact, many people who smoke get lung cancer.
D. However, secondhand smoke is dangerous to all people, old or young.
E. People are becoming very aware of the dangers of secondhand smoke.
F. This smoke is called secondhand smoke.
G. Many people, including doctors, parents, teachers, and others, are concerned about the health risks of cigarette smoking.

Most people know that a wedding ring is symbolic of the bond(连结物) of love and commitment(承诺) between two people. But not everyone knows about the history behind this small yet powerful symbol. The history of the wedding ring goes back not just hundreds but thousands of years. No other currently practiced wedding tradition has been around as long.
The Egyptians were the first recorded civilization to use the wedding ring. In Egyptian hieroglyphics(象形文字) a circle represented eternity. Once a woman accepted the ring she became the “property” of the person who gave it to her and she was in a sense “his.” The first wedding ring could have been made of braided grass or hay (which would have been changed often), ivory, bone, or leather. Eventually, metal was used, but the first wedding bands were crude(未加工的) and rough. However, the sentiment(情感) remained the same-eternal commitment and love.
The Egyptians wore the wedding ring on the left hand because it was believed that a vein(静脉) in the left hand went straight to the heart. This tradition is still commonly practiced today in most parts of the world largely for practical purposes (most people are right handed.)It is worn on the fourth finger of the left hand. But there are some countries and groups which do not follow this tradition. In the Jewish faith, the wedding ring is put on the index finger. Roman Catholics traditionally wore their wedding band on the right hand, and in many countries and regions in Europe some people still follow this tradition.
It is interesting to note that in the long history of the wedding ring that it is only in the last century that men have begun to wear them. However, now both men and women show their love and commitment by exchanging rings on their wedding day.
Once you begin shopping for rings you may be amazed by the choices that await you. There are several different types of metals: traditional gold, white gold, platinum, and titanium. You can have an inscription(刻字) put on the inside of the band(镶边) if you like. Some people are even choosing a tattoo(刺花) band. The styles vary from a simple, yet elegant(优雅的) band to an elaborate(精致的) ring covered with jewels. If you do not buy the wedding and engagement rings as a set you will want to be sure the styles are compatible(一致的). Choose carefully because this choice will need to stand the test of eternity.
1.What would be the best title for this passage?
A.History of rings | B.Interesting facts about rings |
C.Different beliefs about rings | D.The meaning of the rings. |
2. What may the word “eternity” in paragraph 2 probably mean?
A.Elegance | B.Marriage | C.Wedding | D.Foreverness |
3. Which is NOT true according to the passage?
A.The meaning of the rings remained unchanged. |
B.One should be careful of choosing a ring in a shop from different kinds. |
C.Jewish are so faithful to their beliefs to wear rings on the fourth finger. |
D.Now most people in the world still follow Roman Catholics traditionally. |
4.What can we infer from the passage?
A.Men were looked upon by women for thousands years. |
B.Only women have the right to make themselves beautiful. |
C.women wore rings thousands of years earlier than men. |
D.You can have an inscription put on the inside the band. |
