Algae(水藻) are very simple plants. They grow in fresh water or salty water. Seaweed is algae that grow in salty water. Seaweed is red or brown in color. The Japanese people use these plants from the sea in many ways. From it, they make a food called Kombu. Kombu is seaweed that has been dried, cooked and pressed together. Then it is dried again and cut into long pieces. The Japanese eat a lot of Kombu and like it very much.
Japanese farmers often use seaweed as fertilizer. It makes their plants grow better. Many farmers also find seaweed makes a fine food for their animals.
From seaweed the Japanese also get iodine(碘), which they sell to other countries. Iodine is used in many ways all over the world. It is used in making medicine. It is added to the salt we use at the table. Scientists even use one form of iodine to “ seed clouds” when they want rain to fall.

阅读下面短文,从A、B、C、D四个选项中选出最佳选项,并在机读卡上相应番号处将该项涂黑。
People who show confidence really seem to have it made. They seize more rewarding careers, keep good relationships, and just seem to do everything with more styles than the rest of us.
So what is the secret? There isn’t one. Self-confidence is a skill and habit that anyone can learn to develop. And although people who are raised in an encouraging environment with confident role models have a hard start in self-confidence development, we all can learn to become more confident at any age.
Try these simple tips for practicing and increasing your self-confidence levels:
Dare to fail. Anybody who’s out there bravely performing is going to fail repeatedly. If you are not failing, you are not trying. So don’t take failure too hard or too personally. Just learn to deal with it and use its lessons to keep improving.
When in doubt, pretend you know what you are doing. Because, if you are confident of your abilities, by the time you have done it, you will be experienced.
Dress for success. You don’t have to be beautiful to be confident. Make the most of your own unique physical characters and weaken your disadvantages.
Listen to yourself. You are the only person who knows what’s right for you. Don’t put others’ opinions above your own inner voice.
Build a confident vocabulary. Stop putting yourself down and give up continually blaming your tiny weaknesses. Learn to show up your strong points and the world will learn to see and celebrate them with you.
Pass on the praise. Praise others for their virtues and strengths. This practice will not decrease your confidence, but help increase it.

Dolphins and sharks are showing up in surprisingly shallow
water just off the Florida coast. Mullets, crabs, rays and small
fish gather by the thousands off an Alabama pirer. Birds covered in
oil are crawling deep into marshes (沼泽), never to be seen again.
Marine scientists studying the effects of the BP disaster(英国石油公司漏油事件)are seeing
some strange phenomena. Fish and other wildlife seem to be fleeing the oil out in the Gulf and clustering in cleaner waters along the coast in a trend that some researchers see as a potentially troubling sign. The animals' presence close to shore means their usual habitat is badly polluted, and the crowding could result in mass die-offs as fish run out of oxygen. Also, the animals could easily be captured by their enemies.
The nearly two-month-old spill(漏油)has created an environmental disaster in US history as tens of millions of gallons have flown into the Gulf of Mexico ecosystem. Scientists are seeing some unusual things as they try to understand the effects on thousands of species of marine life.
For nearly four hours Monday, a three-person crew with Greenpeace cruised past delicate
islands and mangrove-dotted inlets in Barataria Bay off southern Louisiana. They saw dolphins by the dozen frolicking(嬉戏)in the oily sheen(光泽)and oil-tinged pelicans feeding their young. But they spotted no dead animals.
"I think part of the reason why we're not seeing more yet is that the impacts of this crisis are
really just beginning," Greenpeace marine biologist John Hocevar said.
The counting of dead wildlife in the Gulf is more than an academic exercise; the deaths will
help determine how much BP pays in damages.
小题1:What do the marine life react to the BP disaster?
A.Birds crawl deep into caves.
B.Dolphins and sharks show up in deep water.
C.Tens of thousands of marine animals are found dead.
D.Sea creatures flee from oil spill, gathering near seashore.
小题2:Which of the following is NOT related to the potentially troubling sign?
A.The usual habitat of deep-water animals is badly polluted.
B.Many animals could be easily eaten by their enemies.
C.Masses of fishes could die due to lack of oxygen.
D.Some dolphins are frolicking in marshes.
小题3:The environmental disaster was caused by    .
A.the damage of the Mexico Gulf ecosystem
B.the lack of environmental sense of BP
C.the nearly two-month-old oil spill
D.the crowding marine life
小题4:What is John Hocevar’s attitude towards the disaster?
A.Worried.B.Disappointed.C.Depressed.D.Hesitant.
小题5:From the passage, we can infer that        .
A.Bp will pay much money according to the number of dead wildlife there
B.marine scientists have seen some strange phenomena
C.the disaster has little influence on dolphins
D.a three-person crew reached no conclusion

Damage to Ozone Layer Gets Worse
In the middle of winter, when snow is falling in many parts of the United States, scientists have sounded a warning to people who plan to spend many hours in the sun this summer.The warning: The sun's summertime rays are more dangerous than once thought.
A team of scientists from 80 nations recently reported to the United Nations that a layer of ozone(臭氧层)in the atmosphere, which protects humans from harmful levels of ultraviolet(紫外线)radiation, will be thinner over the United States this summer.The thinner layer allows more ultraviolet rays from the sun to reach Earth.The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.
Scientists first became concerned about the layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter.The hole was caused in chemicals used in refrigerators and air conditioners.When these chemicals are sent out into the atmosphere, they produce gases that destroy the ozone.
Concern about the protective ozone layer rose more recently when data from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica.Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world.
Although many countries have already begun stopping the use of ozone-destroying chemicals, the new findings are expected to advance the timetable for a total ban of the chemicals.
小题1:The scientists have observed the ozone layer ______.
A.since 1980B.since last winter
C.for more than 20 yearsD.for about one year
小题2:The ozone layer in the atmosphere can ______.
A.do a lot of good to human beings in many ways
B.protect humans from diseases caused by bad weather
C.do a lot of harm to human beings in the summer-time
D.protect humans from harmful levels of ultraviolet radiation
小题3:Scientists first found that there was a hole in the ozone layer ______.
A.above Arctic during the winter in the mid-1980s
B.above Antarctica during the winter in the mid-1980s
C.over somewhere in the north of the equator in 1980
D.over the USA in the summertime in the mid-1980s
小题4:The damage to the ozone layer was caused by ______.
A.the changeable weatherB.ozone-destroying chemicals
C.chemicals from refrigeratorsD.chemicals from air conditioners

Rabbits are easy to raise. They are clean and quiet. They don’t need a lot of room. And it costs a small amount of money to feed them, but you can get a big return.
One male and two females will produce as many as fifty more rabbits in a year. That is enough to provide enough meat for a family. Rabbit meat is high in protein and low in fat.
You don’t have to be a farmer to raise rabbits. You can raise them in the city.
Rabbit houses are easy to make with wood and wire. They don’t have to be very big. But each rabbit must have its own little room in the house. This is very important. Each room should be about 75 centimeters wide, 60 centimeters high and one meter deep.
Fencing is used for the sides and floor of the rabbit house. The holes in the wire fencing should be about one centimeter square. Waste from the animals will drop through the holes. This keeps the rabbit house clean and dry.
Rabbits need a lot of fresh air and sunlight. Cover the sides of the rabbit house only to protect it from rain.
Rabbits eat mostly grass and leaves. Hang feeding containers on the outside of the house to let the rabbits eat whenever they want. They simply pull the grass and leaves through the holes in the fence.
Each room should have fresh water. The water containers should be heavy so the rabbit cannot turn them over. Or you can tie the containers to the fence.
One month after mating(交配), female rabbits give birth to about eight babies. In two months, a baby rabbit should weigh about two kilograms. This is big enough to make a meal for a small family.
Rabbits are also valuable for their fur. It takes time, skill and money to prepare the fur and skin for use. If you have only a few rabbits, it probably would be best to let a tanner(制革工) prepare the fur for you. Skill is also needed to remove the fur from the rabbit.
But rabbits do not have to be dead to be valuable. Many people enjoy keeping rabbits as friendly pets. And rabbit waste makes an excellent fertilizer(肥料). It can be mixed directly into the soil to improve the growth of vegetables, trees, and flowering plants.
小题1:The text is written mainly_______.
A.to explain why rabbits are clean and quietB.to let people know more about rabbits
C.to tell readers how to raise rabbitsD.to introduce a small friendly animal pet
小题2:What is important if you raise rabbits?
A.Holes are needed for waste to drop through.
B.Each rabbit must be given a separate room.
C.Each room must have clean water every day.
D.Feeding containers are hung on the fence.
小题3:Why should the holes in the wire fence be about one centimeter square?
A.Because the holes let in sunlight.
B.Because rabbits like these holes.
C.Because rabbits get food from them.
D.Because waste of rabbits drops through the holes.
小题4:What does the underlined sentence in the last paragraph mean?
A.You don’t have to kill rabbits to make more money.
B.Rabbits cannot be sold to make money when they are alive.
C.Rabbits are more valuable when they are alive.
D.Rabbits have to be killed to be more valuable.

Honestly, since my son was born, I have thought a lot about how to raise a child. I once heard a story that told about when a baby was born. The story said that when a baby was born, a new master was born. The parents of that baby would become the servants. The question is: Why? Based on my observation, this phenomenon is true. Most parents who don't pay much attention to their kids have difficulties with their kids' attitude.
I'll make a comparison of how two families raise their children. The first one is a family with three children. Both mother and father never say "No" to their children's demands. As a result, all of their children became stubborn and won't listen to their parents’ words, "We can't."
The second family educated their children strictly from one year old to high school. The parents never approved or agreed directly to give their children what they wanted. They always postponed one or two days, even if they could afford it. Due to the way their parents educated them, these children understood that if they wanted something, they had to wait or they had to make an effort first. As a result, all the kids from the second family successfully graduated from university on time.
In my opinion, if we want to be successful parents and raise our children well, we have to start disciplining them when they are toddlers but not wait until they become teenagers.
小题1:Why did the writer give two different stories in this passage?
A.To help prove his opinion about raising a child.
B.To list different ways that parents may take.
C.To criticize some parents’ foolish action.
D.To prove that his way of education is right.
小题2:What does the underlined word “postponed” in the third paragraph mean?
A.Carried out at once.B.Gave up.
C.Put off.D.Made a decision.
小题3: In the writer’s opinion, which of the following about raising a child is TRUE?
A.Children should be respected once they were born.
B.Parents should educate their children as early as possible.
C.It is right time to educate their children when they are teenagers.
D.Children should be helped whenever they make mistakes.
小题4: What do you think is the best title of this passage?
A.Make a comparison of how two families raise their children
B.To be successful parents
C.How to raise children well
D.Educate children strictly from one year old to high school

Cities need to put efforts to deal with pollution and clear the air.
Chinese cities will need to put efforts to clear up the sky when a new department to improve regional air quality is set up by 2015, according to the latest plan released by the State Council.
Besides the existing pollution control program for S02, regional emission caps (区域排放上限) for other certain chemicals will be established in the three key air polluting areas— rhe Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region.Coal-consumption caps will also be tried out in some areas, according to the plan.
The plan is aimed at dealing with regional air pollution—such as acid rain and smog—which have become increasingly obvious in China in recent years and caused a severe threat to people's health, Zhang Lijun, vice-minister of environmental protection, said in an interview on Monday.
The air quality in a city affects the regions nearby because pollutants (污染物)can travel through the atmosphere, said Chai Fahe, vice-director of Chinese Research Academy of Environmental Sciences.
“So efforts to reduce air pollution in a single city, targeting a certain pollutant will not oe enough," Chai said.
Zhang said the country's major industrial districts—the Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region—have recorded more than 100 misty days annually in recent years.
These three regions, home to at least 200 million people, occupy only 6.3 percent of the country's area but consume 40 percent of the country's coal and produce half of its steel, according to official figures.
Studies also show that the visibility (能见度) in eastern regions of China has dropped by 7 to 15 km compared to that in the early 1960s, as a result of air pollution.
Liaoning province, the Shandong Peninsula, Wuhan in Hubei province and its surrounding area, the Changsha-Zhuzhou-Xiangtan region in Hunan province, the Chengdu-Chongqing region, and the western coast of the Taiwan Straits are also listed as areas to carry out such regional air pollution control programs, according to the plan.
The new plan also requires an improved air quality system, which will measure the pollution levels."The current system, which only measures some major pollutants, cannot reflect the true picture." said Chai.
小题1:It will not be enough to reduce air pollution in a single city because ______.
A.air pollution has been becoming more and more serious in recent years
B.air pollution like acid rain and smog is threatening people's health
C.air pollutants in a city can travel in the sky and affect nearby areas
D.air pollutants stay in fixed places over the cities
小题2:Suppose the visibility in eastern regions of China was 130 km in the early 1960s, the visibility there nowadays is           .
A.123 to 115 km
B.137 to 145 km
C.123 to 145 km
D.115 to 137 km
小题3:The main purpose of the passage is        .
A.to inform readers of the damage caused by air pollution
B.to introduce the new plan to control air pollution
C.to provide official figures of air pollution levels
D.to point out the regions affected by air pollution
小题4:What does the underlined phrase "the true picture" in the last paragraph mean?
A.The major pollutants.
B.The key polluted areas.
C.The major polluted cities.
