[2020·济南市高三学习质量针对性检测]Children in rural areas of Cambodia often suffer from or even die of preventable illnesses because there is not any soap available.
In 2014, Samir Lakhani, an American college student, saw the issue while volunteering in a Cambodian village. “I remember quite vividly a mother bathing her newborn baby with laundry powder, which is so harmful to the skin，”said Lakhani.“It's difficult for rural Cambodians to access soap. First is affordability. If you earn only $1.50 every day, you won't spend $1 on a bar of soap. Then comes access. The demand is so low that local shops don't stock soap. The last reason, because many Cambodians don't really understand where diseases come from, they don't know how to prevent them, including using soap.”
After figuring out a solution to the problem: the barely used soap in hotels, Lakhani started asking hotels to donate leftover soap.“They were all eager to help，” he explained.
Lakhani registered Eco－Soap Bank shortly afterwards. Soon, he received enough funds to hire disadvantaged Cambodian women to collect and reproduce the used soap.
Today, the organization has four recycling centers across the country, providing jobs to 35 local women. And so far, some 174,000 bars of soap have been donated, about 24,000 pounds of soap has been recycled, and hygiene(卫生) has been improved for about 661,000 people.“We are killing_three_birds with one stone，” Lakhani said.
When it comes to the future of Eco－Soap Bank, Lakhani said, “We've just scratched the surface. Lack of hygiene is not something unique to Cambodia. The demand for improved hygiene in the developing world is huge, and much remains to be done. We're looking at seven countries to expand to in the near future.”
1．Which of the following is not mentioned as the reason why rural Cambodians don't use soap?
A．Poverty. B．Inaccessibility.
C．Unawareness. D．Tradition.
2．What does the underlined part “killing three birds”in Paragraph 5 refer to?
A．Saving soap, curing diseases and providing education.
B．Stopping pollution, providing jobs and inspiring donation.
C．Reducing waste, providing employment and improving health.
D．Recycling waste, helping charity and improving community hygiene.
3．What can we infer about Eco－Soap Bank?
A．It won't be long before it expands to the whole world.
B．There's little it can do without other countries' assistance.
C．It will make greater contributions to the developing world.
D．It will soon settle the problem of poor hygiene in Cambodia.
4．What do we know about the text?
A．Eco－Soap Bank helps improve hygiene.
B．Cambodian women have a bright future.
C．A US young man calls for helping poor countries.
D．Lack of hygiene remains a serious problem in the world.

[2020·贵阳市高三摸底考试]Many of us think, wrongly, that the moon doesn't change. For example, the Tang dynasty poet Zhang Ruoxu once wrote that “Generations have come and passed away; From year to year the moons look alike, old and new.”
However, a new study published in the journal Nature Geoscience shows that the moon is in fact slowly shrinking over time. For the study, a group of US scientists examined and analyzed thousands of photographs taken by the NASA's Lunar Reconnaissance Orbiter Camera (月球勘测轨道飞行器照相机). They found that there were lots of faults(断层) on the surface of the moon. These faults were formed by recent movement on the moon.
According to NASA, the moon is made up of pieces of rocks with a hot core. The moon continued to expand as it was born. But in this process, it released energy and cooled down. Then it began to shrink, in a way comparable to the shrinking of a grape into a raisin. Over the past several hundred million years, it has become 46 meters “skinnier”. But due to its hard and rocky layer, the moon's surface
continues to push up.“Some of these quakes can be fairly strong, around five on the Richter scale(里氏震级)，”said Thomas Watters, a senior scientist at the Smithsonian's National Air and Space Museum in the US.
But does that mean the moon is a dangerous place that human shouldn't try to explore and live on in the future? Maybe not, reported The Telegraph.“This isn't anything to worry about. The moon may be shrinking, but not by much. It's not going anywhere，”Watters comforted us.
The new discovery proves that the idea that the moon is a dead, boring place is wrong.“We have been to the moon and we've done some great science, but there is still a lot we don't know. The moon is shrinking — we didn't really realize that until recently. It's a much more active and interesting place than we thought and we should explore that，” NASA scientist Nathan Williams said.
5．Which point of view about the moon may the writer agree to?
A．It stays the same as before.
B．It is becoming slightly smaller.
C．It is getting older and older.
D．It has passed away.
6．What can we learn about the moon from the third paragraph?
A．It has become 46 meters fatter due to expanding.
B．It has changed from a grape into a raisin in recent years.
C．It quakes even at seven on the Richter scale.
D．It has a hot core and releases energy during expanding.
7．Who thinks that we needn't worry about the moon?
A．Zhang Ruoxu. B．Thomas Watters.
C．Nathan Williams. D．The journalist.
8．What does Nathan Williams think of the moon?
A．It is a dead and boring place.
B．It has lots of faults on the surface.
C．It is valuable to do more science.
D．It isn't a place where we can live.
