Starting in l972，the National Park Service established a policy for forest fires calle Natural Burn．It was acknowledged that some forest fires，such as those caused by lightning were necessary for forests to maintain balanced ecosystems，so the fire should be allowed to burn．However, a big fire in Yellowstone National Park in l988 caused this policy to be abandoned since the fire was initially allowed to burn yet soon out of control．As a result，the fire of l988 destroyed much of Yellowstone，which is America’s oldest and most beloved national park．Massive areas of plants were destroyed，and large empty spaces and acres of burned and blackened trees greeted visitors．The rivers and streams were choked with ash，and the ecosystem of the park was changed beyond repair.
In addition，great numbers of animals were killed by the fires that bumed out of control. The fires were driven by high winds，moving as many as ten miles a day．Many small animals died in the flames．The fires’ rapid advances gave the wildlife little chance to escape. Even today，few of these small forest animals have returned to live in the park. In the years immediately following the fires，the numbers of visitors declined rapidly．No one was interested in seeing a blackened and treeless park on vacation．Yellowstone had previously been famous for its amazing views and unique geological formations such as the geyser Old Faithful. But now its reputation as America's wonder is damaged permanently.
小題1:Natural Burn was adopted because some forest fires were        
A．hard to put out
B．started by lightning
C．good for the balance of nature
D．a(chǎn)pproved by National Park Service
小題2:The big fire in Yellowstone in 1988         ．
A．became out of control at first
B．destroyed the park completely
C．was allowed to burn continuously
D．brought the natural burn policy to an end
小題3:Why were so many animals killed in the big fire?
A．Because winds were blown from high places．
B．Because the animals moved only ten miles a day．
C．Because the animals lived in lower places．
D．Because strong winds contributed to the fire a lot．
小題4:Yellowstone was famous for its        ．
A．rare animalsB．unique plantsC．beautiful sceneryD．little streams
小題5:The text probably comes from   ．
A．a(chǎn) science fiction B．a(chǎn) news report
C．a(chǎn) commercial adD．a(chǎn) geography magazine

小題1:C

試題分析:從1972年以來國家公園管理局頒布了一項政策：對于由閃電引起的自然火災(zāi)采取放任態(tài)度，認為這有助于自然平衡。但是1988年黃石自然公園的大火發(fā)生后，這項制度被廢除了，因為火災(zāi)會帶來巨大的損失。
小題1:C細節(jié)理解題。根據(jù)文章首段such as those caused by lightning were necessary for forests to maintain balanced ecosystems，可知在過去人們認為自然火災(zāi)會對生態(tài)平衡有益，答案選C。
小題2:D細節(jié)理解題。根據(jù)第一段中However, a big fire in Yellowstone National Park in l988 caused this policy to be abandoned可知黃石火災(zāi)的發(fā)生結(jié)束了這一制度，故D選項正確。
小題3:D細節(jié)理解題。根據(jù)文章第二段中The fires were driven by high winds，moving as many as ten miles a day．Many small animals died in the flames．可以判斷因為大風(fēng)助長了火勢，很多動物來不及逃走就被燒死了，所以選D。
小題4:C細節(jié)理解題。從文章第二段Yellowstone had previously been famous for its amazing views and unique geological formations such as the geyser Old Faithful.可知黃石公園因為自然風(fēng)光而聞名，答案選C。
小題5:本文介紹的是自然火災(zāi)對于森林的影響，屬于自然地理范疇，由此判斷文章應(yīng)選自地理雜志，所以答案選D。

(2013·高考天津卷，D)When asked about happiness，we usually think of something extraordinary，an absolute delight，which seems to get rarer the older we get.
For kids，happiness has a magical quality.Their delight at winning a race or getting a new bike is unreserved (毫不掩飾的)．
In the teenage years the concept of happiness changes.Suddenly it’s conditional on such things as excitement，love and popularity.I can still recall the excitement of being invited to dance with the most attractive boy at the school party.
In adulthood the things that bring deep joy－love，marriage，birth－also bring responsibility and the risk of loss.For adults，happiness is complicated (復(fù)雜的)．
My definition of happiness is “the capacity for enjoyment”．The more we can enjoy what we have，the happier we are.It’s easy to overlook the pleasure we get from the company of friends，the freedom to live where we please，and even good health.
I experienced my little moments of pleasure yesterday.First I was overjoyed when I shut the last lunch­box and had the house to myself.Then I spent an uninterrupted morning writing，which I love.When the kids and my husband came home，I enjoyed their noise after the quiet of the day.
Psychologists tell us that to be happy we need a mix of enjoyable leisure time and satisfying work.I don’t think that my grandmother，who raised 14 children，had much of either.She did have a network of close friends and family，and maybe this is what satisfied her.
We，however，with so many choices and such pressure to succeed in every area，have turned happiness into one more thing we’ve got to have.We’re so self­conscious about our “right” to it that it’s making us miserable.So we chase it and equal it with wealth and success，without noticing that the people who have those things aren’t necessarily happier.
Happiness isn’t about what happens to us－it’s about how we see what happens to us.It’s the skillful way of finding a positive for every negative.It’s not wishing for what we don’t have，but enjoying what we do possess.
小題1:As people grow older，they________.
A．feel it harder to experience happiness
B．a(chǎn)ssociate their happiness less with others
C．will take fewer risks in pursuing happiness
D．tend to believe responsibility means happiness
小題2:What can we learn about the author from Paragraph 5 and 6?
A．She cares little about her own health.
B．She enjoys the freedom of traveling.
C．She is easily pleased by things in daily life.
D．She prefers getting pleasure from housework.
小題3:What can be inferred from Paragraph 7?
A．Psychologists think satisfying work is key to happiness.
B．Psychologists’ opinion is well proved by Grandma’ case.
C．Grandma often found time for social gatherings.
D．Grandma’s happiness came from modest expectations of life.
小題4:People who equal happiness with wealth and success________.
A．consider pressure something blocking their way
B．stress their right to happiness too much
C．a(chǎn)re at a loss to make correct choices
D．a(chǎn)re more likely to be happy
小題5:What can be concluded from the passage?
A．Happiness lies between the positive and the negative.
B．Each man is the master of his own fate.
C．Success leads to happiness.
D．Happy is he who is content.

They can be seen more frequently than ever before on college campuses, wearing flannel(法蘭絨) and thick­framed glasses while listening to music. One might find them playing unusual musical instruments, shopping at second­hand stores or expressing themselves in other unique ways.
They call themselves hipsters. Being “hip” used to mean following the latest fashion. But gradually the word has become a sign of “being cool, unique and unusual”．
Hipsters value independent thinking, progressive politics, an appreciation of creativity and intelligence. Hipsters take pains and pride in not being mainstream. However, their culture has become quite trendy. This irony(諷刺) is central to their culture and offers an interesting conflict.
“I do take things in the mainstream with a positive attitude，” says Ben Polson, a college student at Brown University. “But sometimes I also question what determines popularity, especially regarding music.” Polson represents many hipsters.
When less­known bands become popular, they often lose their former fan base in exchange for a new one. There is a famous hipster saying that goes, “I used to like that band before it got popular，” Polson quoted.
According to Polson, bands' music changes when they go mainstream. They become less experimental, doing things just to save popularity and fans. The original elements that we were drawn to slowly disappear for the sake of popularity.
Many young adults have started to view hipsters' outlook as cool and they are adopting hipsters' anti­mainstream culture mind to themselves. This has led to specialized brands, stores and music for the hipster consumers. But on the other hand, some such stores, including clothing labels Urban Outfitters and American Apparel, have gained mainstream popularity. This has seemingly made the anti­mainstream culture become weaker.
“A lot of people that are self­defined hipsters aren't really hipsters. They're just trying to act as hipsters to seem cooler，” says Amanda Leopold, a college student from Oberlin College, US. Although Leopold has many unusual tastes and seems quite individualist, she refuses to classify herself as a hipster.
小題1:In the passage, hipsters refer to people ________.
A．who are fans of pop music
B．who study in different colleges
C．who appear cool and unusual
D．who try to attract others
小題2:According to the author, ________.
A．hipsters are the pioneers of the mainstream
B．hipsters are unhappy with the mainstream
C．hipsters' culture exists mainly in music field
D．hipsters' culture can also become popular
小題3:What is the main idea of the seventh paragraph?
A．Urban Outfitters and American Apparel are famous clothing labels.
B．Hipster consumers have more specialized brands, stores and music.
C．Anti­mainstream culture can gain mainstream popularity.
D．The culture of hipsters is becoming more and more terrible.
小題4:When describing hipsters, the author speaks ________.
A．in an ironic voiceB．in an objective voice
C．in an angry voiceD．in a funny voice

You may think that sailing is a difficult sport, but it is really not hard to learn it．You do not need to be strong．But you need to be quick．And you need to understand a few basic rules about the wind.
First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat．The wind direction tells you what to do with the sail.
Let's start with the wind blowing from behind．This means the wind and the boat are going in the same direction．Then you must always keep the sail outside the boat．It should be at a 90° angle (角度) to the boat．Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat．In this case, you must keep the sail half way outside the boat．It should be at a 45° angle to the boat．It needs to be out far enough to catch the wind, but it shouldn't flap (擺動)．It shouldn't look like a flag on a flagpole．If it is flapping, it is probably out too far, and the boat will slow down.
Sailing against the wind is not possible．If you try, the sail will flap and the boat will stop．You may want to go in that direction．It is possible, but you can't go in a straight line．You must go first in one direction and then in another．This is called tacking．When you are tacking, you must always keep the sail inside the boat.
小題1:What should you consider first while sailing?
A．Sailors' strength. B．Wave levels.
C．Size of sails. D．Wind directions.
小題2:What does the word “It” underlined in Paragraph 4 refer to?
A．The boat. B．The sail.
C．The wind. D．The angle.
小題3:What do you have to do when sailing against the wind?
A．Move in a straight line. B．Allow the sail to flap.
C．Lower the sail. D．Tack the boat.
小題4:Where can you probably find the text?
A．In a popular magazine. B．In a tourist guidebook.
C．In a physics textbook. D．In an official report.

It all began with a stop at a red light.
Kevin Salwen was driving his 14-year-old daughter, Hannah, back from a sleepover in 2006 . While waiting at a traffic light, they saw a black Mercedes Coupe on one side and a homeless man begging for food on the other.
“Dad, if that man had a less nice car, that man there could have a meal.”Hannah protested. The light changed and they drove on, but Hannah was too young to be reasonable. She pestered （糾纏）her parents about inequity, insisting that she wanted to do something.
“What do you want to do?” her mom responded. “Sell our house?”
Warning! Never suggest a grand gesture to an idealistic teenager. Hannah seized upon the idea of selling the luxurious family home and donating half the proceeds to charity, while using the other half to buy a more modest replacement home.
Eventually, that’s what the family did. The project —crazy, impetuous （魯莽的） and utterly inspiring — is written down in detail in a book by father and daughter scheduled to be published next month: “The Power of Half.” It’s a book that, frankly, I’d be nervous about leaving around where my own teenage kids might find it. An impressionable child reads this, and the next thing you know your whole family is out on the street.
At a time of enormous needs in Haiti and elsewhere, when so many Americans are trying to help Haitians by sending everything from text messages to shoes, the Salwens offer an example of a family that came together to make a difference — for themselves as much as the people they were trying to help. In a column a week ago, it described neurological evidence from brain scans that unselfishness lights up parts of the brain normally associated with more primary satisfaction. The Salwens’ experience confirms the selfish pleasures of selflessness.
Mr. Salwen and his wife, Joan, had always assumed that their kids would be better off in a bigger house. But after they downsized, there was much less space to retreat to, so the family members spent more time around each other. A smaller house unexpectedly turned out to be a more family-friendly house.
小題1:The best title for the passage should be “______”.
A．The Less, the Better
B．An Expected Satisfaction
C．Something We Can Live Without
D．Somewhat Crazy but Inspiring
小題2:What does the underlined word “inequity” most probably mean in Paragraph 3?
A．Unfairness.B．Satisfaction.
C．Personal attitude.D．Reasonable statement.
小題3: What does the underlined sentence “Never suggest a grand gesture to an idealistic teenager.” means? ______
A．Never give a quick answer to an idealistic teenager.
B．Unless a child is realistic, never give an answer immediately.
C．Give an answer if the child is reasonable.
D．Don’t respond to a child's demands firmly without consideration.
小題4: What can we learn from the last paragraph?
A．The Salwens regretted selling their house.
B．The relationship between the family members of the Salwens is much closer.
C．Small houses can bring happiness.
D．The Salwens intend to buy another big house.
小題5:Which of the following statements is TRUE according to the passage?
A．Mercedes Coupe is only an ordinary car which is quite cheap.
B．Unselfishness has nothing to do with people’s primary satisfaction.
C．Hannah asked her parents to do something charitable and they sold their house.
D．The writer’s children asked him to sell their house.

Our teacher asks us to keep a diary in English. I enjoy doing so because I          keeping a diary in English is one of the effective ways to      our English writing ability.

As far as I am concerned, my suggestion is that we          always have a notebook and a Chinese-English dictionary within easy reach.

Sushi is a kind of food made with a mixture of cooked or raw fish, vegetables, and rice. Although Sushi is most commonly considered to have its origin in Japan, it actually began in China during the 7th Century.
At that time, any fish caught had to be preserved. Raw fish was cleaned and then pressed between layers of heavy salt. After a couple of months, the whole process was complete. Over time, a discovery was made that by rolling the fish in rice that had been soaked in vinegar the fish was easily fermented (發(fā)酵) in a few days rather than months. The rice was then thrown away and the fish was eaten. However, with a food shortage, people began consuming the rice as well as the fish and thus, Sushi today as we know was born. However, in the 1800s, a famous chef by the name of Yohei created two styles of Sushi—one called Edo, and the second, Osaka, for two cities.
Sushi is usually consumed with hot green tea. Also, Gari is offered free and eaten between bites to create a better taste. Two kinds of sauce are usually available: one is soy sauce, which is poured on most kinds of Sushi; the other is a thick sweet sauce used on eel (鰻魚).
Sushi has taken the world by storm and today is a multi-billion dollar industry. Its popularity continues to rise because people are looking for healthy food that is quick and easy to make. With such unbelievable popularity as well as the health benefits of eating Sushi, it is likely that this food will continue to be a part of everyday life for many more centuries to come.
小題1:Two kinds of Sushi, Edo and Osaka, were probably named after _______.
A．the chef’s nameB．their birthplaces
C．the name of fishD．some kinds of food
小題2:When people eat Sushi, Gari is used to _______.
A．keep Sushi last long
B．make green tea better
C．digest Sushi more quickly
D．make Sushi more delicious
小題3:Why do people like Sushi today?
A．It is cheap and delicious.
B．It is served with free Gari.
C．It is beneficial to people’s health.
D．It is easy to be kept for a long time.
小題4:What can be the best title for the text?
