Described as the world’s most environmentally friendly protein, Solein is made by applying electricity to water to release bubbles of carbon dioxide and hydrogen. Living microbes(微生物) are then added to the liquid to feed on the carbon dioxide and hydrogen bubbles and produce the Solein, which is then dried to make the powder. It’s a natural fermentation(发酵) process similar to beer brewing. The dried Solein has a protein content of 50 percent and looks and tastes just like wheat flour.
“It is a completely new kind of food, a new kind of protein, different to all the food on the market todav in how it is produced as it does not need agriculture.” Dr Pasi Vinikka, the chief executive of Solar Foods told The Guardian. The process used to produce Solein — converting hydrogen and carbon dioxide to calories — is amazing, as the wonder food can be produced anywhere in the world. It’s also 10 times more energy-efficient per hectare than photosynthesis (光合作用), and 10 to 100 times more environment and climate-friendly in water use than animal or plant based food production.
“Solein also contains all the essential amino acids(氨基酸), but because it is produced using carbon dioxide and electricity, it does not require large amounts of land to produce,” the Solar Foods website explains. “Another unique characteristic of Solein is that it is able to take carbon directly from carbon dioxide without needing a source of sugar.”
While Solar Foods does not expect Solein to challenge conventional protein production methods in the next two decades, it does expect it to become a “new harvest” for humanity, which is significant considering so far we have only relied on plants and animals for sustenance. The Helsinki-based company plans to open its first Solein factory at the end of 2021 and scale up production to two billion meals per year by 2022.
1.Which of the following statements best describe the features of Solein?
A.It is a new kind of food containing all the nutrition.
B.It is made from water and carbon dioxide by applying electricity.
C.It is produced without consuming much land and energy.
D.It is a kind of man-made wheat flour.
2.What does the underlined word “converting” mean?
A.relating B.changing
C.contributing D.adapting
3.What can be inferred from the last paragraph?
A.The company thinks Solein would have a rewarding future.
B.Solein is supposed to challenge traditional protein production.
C.There is still a long way for Solein to be put into production.
D.Humans can completely rely on Solein to survive.
4.What’s the author’s purpose in writing this passage?
A.To promote a new kind of technology.
B.To introduce a new kind of food.
C.To make an ad for a new kind of protein.
D.To call on people to protect the environment.

Katharine Meyer Graham was once described as “the most powerful woman in America.” She was not a government official or elected representative. She owned and published The Washington Post. Under her leadership, it became one of the most important newspapers in the country.
Katharine Meyer was born in New York City in 1917. Her father was a successful investment banker and became an important financial official. Her family was very rich. Katharine grew up in large houses in New York and Washington. Her parents were often away from home, traveling and working, Katharine was often lonely. Katherine Meyer graduated from the University of Chicago in Illinois in 1938. In 1933, her father bought a failing newspaper, The Washington Post. It was the least successful one of five newspapers in Washington.
Katharine Graham returned to Washington and got a job editing letters to the editor of her father's newspaper. She married Philip Graham. He was a clerk for Supreme Court Justice Felix Frankfurter but soon accepted a job at his wife's father's newspaper. Mr. Graham improved The Washington Post. He bought Newsweek and several television stations. He also established close ties with important political leaders. However, Mr. Graham treated his wife badly. He had an affair with a young reporter. For many years, Mr. Graham suffered from mental illness. He killed himself in 1963.

She did not think she had the ability to do an important job. She had no training in business or experience in operating a large company. In those days, it was unusual for a woman to be the head of a business. Women were expected to look after their homes and children.
Katharine Graham met with officials of The Washington Post. She was elected president of The Washington Post Company. She had no idea about how to operate a newspaper. So she decided to learn. She began by hiring Benjamin C.Bradlee. He later became chief editor. Mr. Bradlee improved the newspaper. He hired excellent reporters and editors. They began doing important investigative reporting.

Just as the world’s most respected scientific bodies have confirmed that the world is getting hotter, they have also stated that there is strong evidence that humans are driving the warming． Countless recent reports from the world’s leading scientific bodies have said the same thing． For example, a 2010 summary of climate science by the Royal Society stated that: “There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity．”
The idea that humans could change the planet’s climate may be counter-intuitive（与直觉不符的）, but the basic science is well understood． Each year, human activity causes billions of tons of greenhouse gases to be released（释放）into the atmosphere． As scientists have known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket．
Of course, the planet’s climate has always been changing thanks to “natural” factors（因素） such as changes in solar or volcanic（火山的）activity, or cycles relating the Earth’s going around the sun． According to the scientific literature, however, the warming recorded to date matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes．
Even if scientists did discover another reasonable explanation for the warming observed so far, that would beg a difficult question． As Robert Henson puts it in The Rough Guide to Climate Change: “If some newly discovered factor can account for the climate change, then why aren’t carbon dioxide（二氧化碳）and the other greenhouse gases producing the warming that basic physics tells us they should be?”
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without． That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty．
1.In most scientists’ opinion, the global warming is mainly caused by ________．
A． solar activity B． volcanic activity
C． the Earth’s going around the sun D． human activity
2.The text is developed by ________．
A． giving typical examples B． following the order of space

Malaria, the world's most widespread parasitic (寄生虫引起的)disease, kills as many as three million people every year ---- almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect (感染) .They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.
1. According to paragraph 1, many people don't seek care because ___________.
A. they are too poor
B. it is unusual to seek care
C. they can remain unaffected for long
D. there are too many people suffering from the disease
2. People suffering from malaria _____________.
A. have to kill female mosquitoes B. have ability to defend parasites
C. have their red blood cells infected D. have sudden fever, followed by chills
3. Which of the following may be the reason for the wide spread of the disease?
A. Its resistance to global warming.
B. Its ability to pass on the virus frequently.
C. Its outbreaks in cities with large populations.
D. Its ability to defend itself and resist new drugs.
4. It can be inferred from the passage that _____________.
A. no drugs have been found to treat the disease
B. the alternative treatment is not easily available to most people
C. malaria has developed its ability to resist parasites
D. nobody knows what will be the drug to treat the disease
5. Which of the following questions has NOT been discussed in the passage?
A. How can we know one is suffering from malaria?
B. How many people are killed by malaria each year?
C. Why are there so many people suffering from malaria?
D. What has been done to keep people unaffected for long?
