【题目】With only about 1,000 pandas left in the world, China is desperately trying to clone (克隆) the animal and save the endangered species (物种). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.

Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A& M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.

It is estimated that as many as 2,000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.

This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.

The entire procedure could take from three to five years to complete.

“The nuclear transfer (核子移植) of one species to another is not easy, and the lack of available (capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and ifs difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort, adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.

“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”

【题目】 The CoVID-19 and flu are both respiratory infectious diseaseswith similar symptoms including fever and coughbut they aren't the same.

Both the CoVID-19 and flu are diseases caused by a virus. In the case of flu the pathogens(病原体)are flu virusesand for COVID-19it is a novel coronavirus(新型冠状病毒).

Common symptoms for flu and novel coronavirus are nearly identical-fevercough and tiredness sometimes sore throat and diarrhea. In several cases they result in pneumonia(肺炎)and even death in the worst cases. Flu has seasonal ups and downs. Although it can exist all year roundthe virus infects more people in winter and spring. As for the novel coronavirusthe median age for the infected is 51.But the novel coronavirus is a brand new virus no one has total immunity no matter their age.

Both the flu and the novel coronavirus are transmitted in the similar waysby direct contact with infected patients or small droplets from the nose or mouth when a person with virus coughs or breathes.

FIu can be spread by an infected person for several days before their symptoms appear. As for the novel coronavirusspread might be possible before people show symptomsbut this is not thought to be the main way the virus spreads.

For the novel coronavirusthere is also a risk for aerosol transmission(气溶胶传播)In health facilitiespeople may catch the virus if they breathed in aerosol, the suspension of find solid or liquid particles in the air, which have been contaminated by the virus. The novel coronavirus has also been found in patients’ fecal (排泄物) samples, but fecal-oral transmission does not appear to be a major transmission route.

1What can we learn about the novel coronavirus?

A.It has seasonal changes

B.It causes less deaths than flu.

C.It may spread among people of all ages.

D.It only spread after people show symptoms

2Which of the following is not the way the novel coronations transmit?

A.aerosol transmissionB.contact transmission

C.fecal-oral transmissionD.age transmission

3The author’s main purpose of writing the article is probably to .

A.prove that flu has less harm to humans than coVID.1g

B.raise people's awareness of protecting their health

C.prove that COVID-19 won't cause human deaths

D.provide some suggestions to avoid CoVID-19 infection

4What does the passage mainly talk about?

A.New treatment on the novel coronavirus

B.the latest research on the COVID-19 and flu

C.the difference between the novel coronavirus and flu

D.how to identify the CoID-19 and flu on symptoms

【题目】Directions: Fill in each blank with a proper word chosen from the box. Each word can be used only once. Note that there is one word more than you need.

Why India’s ‘Pink City’ is a Photographer’s Heaven

The city of Jaipur is one of India’s wonders. It 1 some of the country’s most decorative royal palaces—elegant structures designed hundreds of years ago that still attract visitors today. Largely built in the 1700s, Jaipur is surrounded by a city wall and several 2 castles. Considered as a commercial center, it was ahead of its time due to the use of grid iron (网格状)city planning.

A romantic dusty pink type—which has 3 the city since 1876, after it was painted pink to welcome Queen Victoria’s husband, Prince Albert—gives Jaipur its 4 as the “Pink City”. This 5 beauty is what first brought Hong Kong-based photographers Victor Cheng and Samantha Wong to Jaipur.

Walking in glass skyscrapers for century-old royal palaces and historic castles, the pair—who have 130,000 Instagram followers between them—said that the images they 6 in Jaipur received a lot of response online. “A lot of our followers hadn’t seen this side of India, so we’re happy we were able to show this side of the country.” Cheng said.

For the photographers, one of the city’s most fascinating features is the light pink coloring of its buildings. “The first gates you see when you enter are pink,” said Wong. “Once you’re through, everything around you varies in different 7 of the color—from bright pinks to reddish browns.”

The building is a(n) 8 of the City Palace, and its windows allowed royal women to observe street life without appearing in public. One of Cheng’s most striking photos shows a straight front of the building and its hundreds of windows. The building’s lively coloring also pushed Cheng to take a different 9 to editing than with images of other cities. “I toned down my usual editing process because the pink was so bright in reality,” he said, “I wanted the photos to 10 the actual color I was seeing myself and to maintain its tone.”
