Every year 2.2 million tons of oil are spilled ( 散落,溅出 ) into the ocean. Actually, this only amounts to a small percentage of the total 1.6 billion tons of oil shipped around the world each year.However, this spilled oil has terrible effects on ocean life, including the coastlines where the off washes up onto shore. Some of the largest spills in history were caused by oil tankers running into each other or by an oil tanker sailing into shallow water and hitting the bottom of the ocean. After these spills, officials try to discover who or what was at fault to help prevent similar accidents in the future.
One of the worst oil spills in history occurred along the Alaskan coastline in 1989. In this accident, 42,000 tons of oil spilled from a tanker which resulted in terrible damage to this sensitive natural area. In this spill, the tanker's captain, who was tired from overwork and drinking alcohol, had gone to take a rest. He gave control of the ship to the third mate. The third mate was unfamiliar with the path the ship took, and he ran the ship onto Blighe Reef. Blighe Reef is a natural underwater rock wall near the Alaskan coast. Damaged by the reef, the ship leaked oil out into the ocean. More than 1,600 kilometers of coastline were affected by the oil spill. Some scientists who studied nature in the area guessed that 580,000 birds and 5,500 otters died when the oil from the spill covered their skin. As well, smaller shellfish and other sea creatures were later eaten by seals, whales, and other animals.
The most oil ever spilled was actually dumped on purpose as an act of ecological warfare. The term ecological warfare means to fight by doing harm to nature in the area under attack. In 1990, Iraq sent soldiers into Kuwait and set off the Persian Gulf War. As part of the Iraq war plan,900,000 tons of oil were let out into the Persian Gulf Way Iraq. This oil covered 1,500 square kilometers of water in the Persian Gulf. The oil also damaged 650 kilometers of the coastline of both Kuwait and Saudi Arabia. In some places, oil floating on the water was measured to be 43 centimeters thick. Water birds, water plants, and baby fish were all seriously affected by the oil. The long-term effects of this act on the food chain in the area are bound to cause problems tar into the future.
1.Which cause of oil spills is described in the second paragraph?
A. Dumping B. War
C.Accidents D.Throwing about carelessly
2.The creatures affected by the oil spill near Alaska were_________.
A. birds and otters B. shellfish

Plastic-Eating Worms
Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.
Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms’ chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass — apparently broken down by enzymes (酶) from the worms’ stomachs. Their findings were published in Current Biology in 2017.
Federica Bertocchini, co-author of the study, says the worms’ ability to break down their everyday food — beeswax — also allows them to break down plastic. "Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, "she explains, "The wax worm evolved a method or system to break this bond. "
Jennifer DeBruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?
Bertocchini agrees and hopes her team’s findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process — not simply "millions of worms thrown on top of the plastic."
1.What can we learn about the worms in the study?
A.They take plastics as their everyday food.
B.They are newly evolved creatures.
C.They can consume plastics.
D.They wind up in landfills.
2.According to Jennifer DeBruyn, the next step of the study is to .
A.identify other means of the breakdown
B.find out the source of the enzyme
C.confirm the research findings
D.increase the breakdown speed
3.It can be inferred from the last paragraph that the chemical might .
A.help to raise worms
B.help make plastic bags
C.be used to clean the oceans
D.be produced in factories in future
4.What is the main purpose of the passage?
A.To explain a study method on worms.
B.To introduce the diet of a special worm.
C.To present a way to break down plastics.
D.To propose new means to keep eco-balance.

On April 24th, another natural disaster—the oil spill(泄露) in the Gulf of Mexico, happened.Millions of dollars have been used to help stop the spill and to clean up the animals, beaches, and land spoiled by the oil.Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea.
But governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage.Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run.
Of all of today's environmental disasters, an oil spill may actually be one of the least serious.Although oil is poisonous, it is a natural material.In the end, it breaks down naturally.In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tons of oil into the ocean.If you go there today, you will find it hard to see any sign that it ever happened.
However, we should be thinking more about reducing our dependency on oil.Governments should be encouraging research into new technologies, such as cars run by solar power(太阳能), electricity, hydrogen, and so on.Much of this research, in the past, was stopped by the oil, gas, and coal.
If the world's millions of cars were 10% more efficient(高效的),we would need many fewer tankers crossing the oceans each year.If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too.
1.What is the passage mainly talking about?
A.Oil spills pollution. | B.What oil pollution is. |
C.Oil tanker accidents. | D.How to reduce oil pollution. |
2.How does the author support the idea that oil spills are not as serious as people believe?
A.By giving a description. | B.By making an argument. |
C.By giving an example. | D.By comparing. |
3.Which suggestion is made for reducing oil tank accidents according to the passage?
A.We should build safer tankers in the near future. |
B.We should develop new technologies to cut oil use. |
C.Tankers should not be allowed to sail near the coastlines. |
D.Countries should build more oil pipelines under the sea. |
4.Where can you read this article?
A.In a story book. | B.In a science magazine. |

There are hundreds of publishers across the world and millions of books get printed every year. Moreover, a book can be printed by several polishers.1.
To overcome the problem of identifying books, publishers have come up with a unique numbering system. For instance, if 50,000 copies of The Adventures of Sherlock Holmes are printed by a publisher at one time (called an edition), all of them are identified by one number code. 2. your address begins with your house number, street, locality, state and ends with a statement of the country where you live. An ISBN book number achieves a similar aim of identifying and tracing a book
If you pick up any book, turn it around you will see a number which looks something like this — ISBN 90-70002-34-5. This is called the ISBN number. ISBN stands for International Standard Book Numbering. 3. The ISBN number is divided into four groups that are separated by a space or a hyphen.
The first part of the ISBN identifies the country and is called the Group Identifier. 4.The second part is called the Publisher Prefix. The Publisher Prefix is used to identify the publisher of the book. The publisher prefix may contain up to seven digits.
The third part identifies the title and the edition of the book and so is called the Title Identifier, which may consist of up to six digits. 5.Since you can have the same book from the same publisher but with different editions, the Title Identifier helps to differentiate between them.
The fourth and the final part is called the Check digit, a single digit (from 0 to 9) used to check whether the given ISBN number is correct or wrong. If an ISBN number is incorrect, this means that the book is a version printed illegally.
A.It may consist of up to five digits.
B.So what can the ISBN number do for you?
C.This makes the task of identifying a book very difficult.
D.It is a numbering system that is used to describe the book.
E.Book publishers often come out with newer and updated versions of earlier books.
F.The number Code is your home — address that can only be shared by your parents and
G.The ISBN numbering system helps book stores and book publishers to handle categorize to handle, categorize, store and identify books easily.

The World Health Organization warns that millions of people are dying every year from indoor air pollution. The WHO finds that poor cooking, heating and lighting technologies are killing millions of people each year.
Indoor air pollution results from the use of dangerous fuels and cook-stoves in the home. To help fight the problem, the WHO announced, new guidelines aimed at reducing household pollutants.
WHO officials say nearly three billion people are unable to use clean fuels and technologies for cooking? heating and lighting. And they say more than seven million people die from exposure to indoor or outdoor air pollution each year. Of that number, the WHO says about 4. 3 million people die from household air pollution given off by simple coal cook-stoves. Most of the deaths are in developing countries.
Carlos Dora is Coordinator in the WHO's Department of Public Health, Environmental and Social Determinants of Health. He says people should not use unprocessed coal and kerosene fuel indoors. He says opening a window or door to let out the harmful air will not improve the situation. It will only pollute the outdoors.
WHO officials say indoor pollution leads to early deaths from stroke, heart and lung disease, childhood pneumonia(肺炎) and lung cancer. Women and girls are the main victims. The United Nations found that more than 95 percent of households in sub-Saharan Africa depend on solid fuels for cooking. It says huge populations in India, China and Latin American countries, such as Guatemala and Peru, are also at risk.
Nigel Bruce is a professor of Public Health at the University of Liverpool. He says researchers are developing good cook-stoves and other equipment to burn fuels in a more efficient way.
WHO experts note some new, safe and low-cost technologies that could help are already available. In India, you can buy an induction(电磁) stove for about $ 8.00. And in Africa a you can buy a solar lamp for less than $ 1. 00.
1.What has been done to reduce indoor air pollution?
A. The WHO provided selfless assistance for the poor.
B. People are forbidden to use coal-stoves inside.
C. The WHO issues official advice to cut down pollution,
D. People are taught how to correctly use their stoves.
2.According to WHO officials, we can know that
A. many people refuse to use clean fuels and technologies
B. seven million people die from indoor air pollution
C. simple coal cook-stoves cause too many deaths
D. the processed coal is dangerous to people’s heath
3.It can be concluded from the fifth paragraph that .
A. most children are suffering a lot from lung cancer
B. solid fuels are easily producing pollutants
C. sub-Saharan Africa is the poorest place
D. some countries are at the risk of using up fuels
4.What can we infer from the passage?
A. More and more will die in the future.
B. It is not hard to solve indoor air pollutants.
C. Most people cannot afford a new stove.
D. The WHO will take strong measures.
