DNA(Deoxyribonucleic acid)is one of the most important discoveries in science. DNA is the plan for the human being,as a blueprint is the plan for building. DNA makes a person look the way he does. A person’s DNA comes from a mixing of his parents’ DNA. That’s why a child looks like his parents. But,besides controlling things such as height and hair color,DNA can also give people diseases. Scientists are now studying DNA to cure(治疗) diseases.
In the seventies, scientists developed a process called recombinant (重新组合) or RDNA. Although it sounds difficult to understand,RDNA simply means taking DNA from one animal or plant and putting it into another. By doing so,scientists can create new beings. In doing so,scientists can better understand DNA, especially what parts of DNA do. After they understand DNA,scientists can begin to cure diseases. Often,the new being created itself will be the cure.
Besides curing diseases,RDNA research can also do other things. For example, scientists in Japan have already created “super-trees”. Trees help humans,because they take CO2, which poisons humans, from the air and turns it into oxygen, which lets humans breathe. “Super-trees” do this too,but do it much faster. As things such as cars and factories have already put much CO2 in the area,“super-trees” are badly needed.
Unfortunately,there is serious danger in RDNA research. Scientists want to create animals to cure old diseases,but these new animals may also create new diseases. It will be a serious problem if the animals escape from the science laboratory and into nature. As these animals are not natural, they may let loose many new powerful diseases.
As a result,RDNA research will create many solutions(解决方案),but it will also create many problems.

Beer is one of the world’s most popular drinks. One of beer’s most important ingredients(成分)is water. Beer makers say you need up to five liters(升)of water to make one liter of beer. If water becomes limited, then, will people have to stop making beer? Beer makers have already thought of that possibility. So, in some cities, people are testing out beers made from collected and filtered rainwater.
They are also collecting rainwater and water from the beer-making process for use inside the beer factory. Sierra Nevada is a well-known beer factory in California. It uses rainwater for cleaning and washing toilets. Beer makers understand the importance of saving water. If there is no water, there is no beer.
That is why Stone Beer Company, near San Diego, California, worked with a local water treatment program to make beer. The program is called Pure Water San Diego. It wants to provide one-third of the city’s water by 2035.
Working with Pure Water, the beer factory used purified water that came from wastewater. Wastewater is water that has already been used for showers, washing dishes or toilets.
Stone is a large beer factory. It has customers across the U.S. and Europe. Some of their beers are among the best in the United States. So it was a big deal when Stone released a special beer called Full Circle Pale Ale in March. Many websites and newspapers wrote about the beer. They reported that it was made from “toilet water.” Local television stations recorded people's reactions as they tasted the beer.
Stone later wrote a blog post saying it was not happy with all of the news coverage-especially reports that centered on the idea of “toilet water.” But it was happy that the experiment was a success.
The beer was only made for a special event. Stone Beer is not permitted to sell in stores or at the restaurants.
1.Why do some beer makers use rainwater to make beer?
A. To try new sources of water.
B. To make special taste for beer.
C. To reduce the cost of production.
D. To give up pure water in production.
2.What did Stone Beer Company want Pure Water San Diego to do?
A. Help it to develop new kind of beer.
B. Supply the majority of water to the city.
C. Make waste water clean enough to make beer.
D. Deal with its waste water from the beer production process..
3.What do we know about the special beer?
A. It was welcomed by the public.
B. Few people dared to taste it.
C. It will be sold in large quantities.
D. It received great attention from the media.
4.What did Stone Beer Company think of the reports about the beer?
A. They are satisfying. B. They are disappointing.
C. They are surprising. D. They are beneficial.

Ramadan
Ramadan is one of the most important festivals for Muslims. The name of the festival comes from the Arabic month in which it is celebrated. Ramadan is celebrated in countries all over the world, especially in Africa and the Middle East. The time for celebrating Ramadan varies each year. People celebrate it in the ninth month of the Arabic lunar calendar. During Ramadan, people must not eat during the day: from when the sun comes up to when the sun goes down, people celebrating Ramadan will not eat or smoke. When the sun has gone down, however, the celebration begins. People often stay up all night eating, singing and dancing.
Easter
In late spring, many people around the world celebrate Easter. The festival is a celebration of spring and it is also a religious holiday. It is the time for Easter bunnies and egg hunts, and of course for eating lots of delicious foods.

People celebrate Easter in different ways: in some countries, the Easter Bunny-a big rabbit-will visit people and children will go on egg hunts, looking for eggs and candy that have been hidden by their parents.

高一英语阅读理解中等难度题查看答案及解析
Celebrity (名人) has become one of the most important representatives of popular culture. Fans used to be crazy about a specific film, but now the public tends to base its consumption (消费) on the interest of celebrity attached to any given product. Besides, fashion magazines have almost abandoned the practice of putting models on the cover because they don’t sell nearly as well as famous faces. As a result, celebrities have realized their unbelievably powerful market potential, moving from advertising for others’ products to developing their own.
Celebrity clothing lines aren’t a completely new phenomenon, but in the past they were typically aimed at the ordinary consumers, and limited to a few TV actresses. Today they’re started by first-class stars whose products enjoy equal fame with some world top brands. The most successful start-ups have been those by celebrities with specific personal style. As celebrities become more and more experienced at the market, they expand their production scale rapidly, covering almost all the products of daily life.
However, for every success story, there’s a related warning tale of a celebrity who overvalued his consumer appeal. No matter how famous the product’s origin is, if it fails to impress consumers with its own qualities it begins to resemble an exercise in self-promotional marketing. And once the initial attention dies down, consumer interest might fade, loyalty returning to tried-and-true labels.
Today, celebrities face even more severe embarrassment. The pop-cultural circle might be bigger than ever, but its rate of turnover has speeded up as well. Each misstep threatens to reduce a celebrity’s shelf life, and the same newspaper or magazine that once brought him fame has no problem picking him to pieces when the opportunity appears. Still, the ego’s (自我的) potential for expansion is limitless. Having already achieved great wealth and public recognition, many celebrities see fashion as the next frontier to be conquered. As the saying goes, success and failure always go hand in hand. Their success as designers might last only a short time, but fashion—like celebrity—has always been temporary.
1.Fashion magazines today ______.
A.totally refuse to put models on the cover
B.rarely place models on the cover
C.need not worry about celebrities’ market potential
D.judge the market potential of every celebrity correctly
2.A change in the consumer market can be found today that ______.
A.price rather than brand name is more concerned
B.producers prefer models to celebrities for advertisements
C.producers prefer TV actresses to film stars for advertisements
D.quality rather than the outside of products is more concerned
3.The underlined sentence in Paragraph 4 indicates that any wrong step will possibly ______.
A.shorten the artistic career of a celebrity in show business
B.damage the image of a celebrity in the eyes of the general public
C.cut short the time of a celebrity’s popularity
D.influence the price of a celebrity’s products
4.The passage is mainly about ______.
A.celebrity and personal style B.celebrity and market potential
