3 . Going to the bathroom while floating in space can be tricky. Gravity is very weak in space, meaning toilets cannot flush (冲刷) the same way that they do on Earth. In a new contest, NASA is asking inventors from around the world to develop a new space toilet. The space agency is looking for a design that would work both aboard the International Space Station (ISS) as well as on the moon. NASA plans to use this toilet aboard a future lunar lander as part of the Artemis program, which will send humans to the moon by 2024.

Anyone can apply to this challenge, and the winning design will receive a $20,000 prize. The second-place design will win $10,000, and the third-place winner will win $5,000. The contest includes a “junior” category in which anyone under the age of 18 can apply with their creative space toilet idea. Winners in the junior category will receive public recognition and NASA souvenirs.

Designs should also take up no more than 4.2 cubic feet of space. The toilet itself shouldn’t be louder than 60 decibels, which is about the same volume as a bathroom fan. The space toilet will have to be able to collect both urine (尿液) and fecest (粪便) at the same time. It should be able to hold at least a quarter gallon (1 liter) of liquid waste. It should also be able to hold 17.6 ounces (500 grams) of solid waste. The final requirements are that the system must be able to store or get rid of waste, and it should also be able to be cleaned and maintained in five minutes or less.

Hopefully, this toilet will be an improvement on previous systems for waste removal. A waste removal system is a method of disposing of urine and feces. If you are a creative inventor, come and join us!

4 . The vicinity (地区), between southern Angola and northern Namibia, is home to a leafy green plant that can live up to 1,000 years. This “Immortal” plant’s lifespan encourages researchers wondering why, out of all climates the world has to offer, this plant finds itself to thrive in the harsh, dry, and quite unforgiving Namib Desert known to reach less than two inches of rainfall a year.

Welwitschia (千岁兰), meaning “two leaves that cannot die,” in Afrikaans, was discovered by biologists Charles Darwin and the botanist Friedrich Welwitsch, whom the plant was named after in 1859. Andrew Leitch, a plant geneticist at Queen Mary University of London, explains, “Generally speaking, this plant can live thousands of years. When it does stop growing, it’s dead.

Nature Communications, a study published in July, conducted research to discover and identify the magic within Welwitschia’s genetic makeup. Researchers were able to infer, “Approximately 86 million years ago, after a mistake in cell division, the entire Welwitschia genome (基因组) doubled during a time of increased and prolonged drought in the region.” Additional research concluded that repeated genes lost their defining purposes, allowing some to develop new functions. But because DNA reproduction consumes high levels of energy, repeated genes can at times cause more harm than good, especially in severe weather conditions.

This plant also has more magic coming out of its leaves. Unlike most plants, where the leaves grow from the ends of its stem and branches, the Welwitschia’s leaves grow from a “vulnerable” area called the basal meristem (分生组织), which supplies fresh cells to the growing plant. The combination of internal and external factors of the Welwitschia has allowed the plant to continue thriving in extreme temperature conditions. Researchers are hopeful that Welwitschia can also provide insight into the agricultural industry and how we can develop drought tolerant crops.

1. What does the underlined word “thrive” in paragraph 1 mean?

A．Grow well.

B．Fade away.

C．Rise up.

D．Break down.

2. What can we infer from the passage?

A．The Welwitschia must have a life span of several thousand years or more.

B．Copied genes can do more harm than good due to energy consumption.

C．Biologist Charles Darwin named the Welwitschia in 1859.

D．The Welwitschia’s leaves, like most plants, grow from the basal meristem.

3. What can Welwitschia do according to researchers in Paragraph 4?

A．Solve the crisis facing the agricultural industry.

B．Give a deeper understanding of the agricultural industry.

C．Be planted as drought tolerant crops in the future.

D．Not bear extreme temperature conditions.

4. Which can be the best title for the text?

A．Copied Genomes of a Long-lived Plant.

B．Two Leaves That Cannot Die.

C．The “Immortal” Plant Tells Its Tale.

D．Agricultural Development with Welwitschia.

7 . The Harrow brewery was losing ground year after year because sales were so low that there was no money to advertise on television. It was a vicious circle.

As a salesman, Andrew ________ suggested that the factory director go to the TV station to make an advertisement, but the factory director ________. Andrew decided to take a risk on “what he wanted to do”. He took out a ________ to do the sales work in the factory. While he was wondering how to make the most economical ________, he wandered into Julen Square in central Brussels. ________ it was late at night, there were still many people in the square. The bronze statue of a boy urinating (撒尿) in the center of the square was Julien, a hero who is ________ for saving the city. Of course, the urine from the statue was tap water. Andrew was ________ by a group of naughty children in the square who used their own empty mineral water bottles to splash each other with tap water from the ________.

The next day, people passing by the square found Julien’s urine ________ a golden “Hello” beer. Next to the statue, a large sign   ________, “Free Tasting of Harrow Beer.” One by one, people all over the city ________ with their own bottles and cups from home to pick up the beer. TV stations, newspapers, and radio stations ________ to write about it. Andrew ________ to get the Harrow beer on TV and in newspapers without spending any money.

8 . Many Americans suffer from chronic (慢性的) conditions connected to their diets.    1    .

If you are looking for a health super-hero, head to the grocery store.    2    . That is not an exaggeration (夸张). A study found that people of any age who started including healthy foods in their diets improved their chances of living longer. Replacing one serving of red meat a day with one serving of nuts, for instance, was related to an 8-17 percent reduced risk of early death.    3    .

Lentils (扁豆) contain the highest amount of protein of any plant. They also provide excellent amounts of iron, folate (叶酸), and magnesium.    4    . A quarter cup of dry lentils contains about 13 grams of fiber. A quarter cup of kidney beans has about half that. They are consumed in the Blue Zones, areas of the world famous for having the longest-living and healthiest people.

Salmon (鲑鱼) is rich in protein, omega-3s, B vitamins, vitamins D and A.     5    . Specifically, they help protect against age-related brain and eye diseases, reduce the risk of heart disease and depression and maintain healthy skin.

Blueberries have plenty of nutrition carried in such tiny berries!They have plenty of fiber to keep you full and make your colon moving. They have folate which helps make DNA. They also have Vitamins C to help create collagen in your skin and other nutrients which protect our cells from damage.

A．But how do you choose the best options for you?

B．These nutrients are important for good health．

C．However, some nutritious foods can make you healthier with every bite．

D．As a great source of fiber,t hey can also help control blood sugar levels．

E．Studies show that these nutrients in seafood improve babies’s brain development, including an IQ boost．

F．What’s more, belonging to the legume (豆类) family, they have more fiber than beans．

G．Some foods can fight diabetes, heart disease, or cancer-in other words, they can save your life．

9 . After two years of pandemic living, people are collectively ready for a vacation. No matter how much we might like to, though, it’s not always possible to take a vacation from COVID-19. The virus is still circulating widely, including in popular tourist destinations like the U.K., Germany, France, and Italy. That means getting sick while traveling is a real possibility — and one that can turn into an expensive and stressful logistical headache.

What happens if you get COVID-19 while traveling internationally? To enter the U.S., international travelers currently need either a negative COVID-19 test result obtained within one day of their flight or proof that they have recovered from COVID-19 in the last 90 days. (This policy applies to both U.S .citizens and non-citizens, but children younger than 2 are exempt.) Without one of those documents, you cannot board a U.S.-bound flight. If you test positive, you should isolate and delay travel for 10 days, according to the U.S. Centers for Disease Control and Prevention (CDC).

But where do you stay if you need to quarantine (隔离) abroad?And who pays for extended accommodations and rescheduled flights?Specifics vary from country to country, but the short answer is that travelers are often on the hook. Exceptions to the test-to-return policy may be granted on an “extremely limited” basis, such as in the event of an emergency medical evacuation or humanitarian crisis, the CDC says-but the average vacationer won’t have many options beyond paying to extend their stay.

A spokesperson for the State Department Jeanna Smialek said travelers who must isolate should contact their hotels and airlines to arrange accommodations and re-book travel, and, if necessary, seek assistance from their nearest U.S. embassy or consulate. The spokesperson added that U.S. citizens traveling abroad are subject to local quarantine rules, which may differ from those of the U.S. CDC.

1. What do you need to enter the US if you get COVID-19 while traveling internationally?

A．A negative COVID-19 test result．

B．A certificate of health recovery in the last 90 days．

C．Two weeks’ travel delay．

D．Extended accommodations and rescheduled flights．

2. What does the underlined phrase “on the hook” in paragraph 3 refer to?

A．Should pay the money．	B．Be pleasant to stay longer．
C．Have no choice but to obey the rule．	D．Be not satisfied with the policy．

3. According to Jeanna Smialek, which one is not true?

A．Accommodations should be booked by travelers themselves．

B．American consulate is accessible to isolated travelers．

C．Travelers who must isolate have certain restrictions．

D．Travelers should obey both local and American quarantine rules．

4. What’s the passage mainly about?

A．How to isolate during the COVID-19．

B．What international travelers should do after test positive．

C．COVID-19 isolation spreads in popular tour destinations．

D．Isolation policies are different among countries．
