1.Dust can cause sore eyes, coughing, hay fever (花粉病) and asthma (哮喘) attacks.2.For instance, dust can be found behind cabinets, on top of doors, windows and so on.

“Are personal sad stories a must to win talent shows?” “Shouldn’t talent be judged on the basis of itself without needing a sad story of struggle to win?” These are questions Sanya Malhotra posed on a recent Facebook post.
This morning I came across this interesting post by Sanya Malhotra. She revealed that she loved dancing and dreamt of becoming an actress, but got defeated in “Dance India Dance” because her background story wasn’t sad and inspiring enough. That’s when she started doubting her artistic gift.
This really set me thinking. Why are people attracted to sob stories? Why do we always appreciate only those people who have achieved something after going through a lot of hardships? Why does the headline of a newspaper “Taxi-driver’s Son Stands First In UPSC Exam” find more readers? I think it is because most people, who are in a similar situation, find it comforting that someone has succeeded with so many hardships. I know it is really very difficult for people with financial, health, or family problems to overcome obstacles and succeed. I really feel proud of them and I am often touched and inspired by their stories.
Now come back to what Sanya has said. I think this is a talent show rather than a story-telling competition. When it comes to a competition of singing or dancing or any fine arts, all the competitors should be judged without any bias (偏见). No one should lose because they don’t have a sad story of struggle to tell. It’s very unfair. They can be given opportunities otherwise, but should not be judged because of their stories.
Maybe, the TV channels do it to attract more viewers, because the most important element of any reality show is these touching stories. But as Sanya has said, it’s unfair to those who haven't such a story and are equally talented.

California’s Yosemite National Park is home to many stunning waterfalls. However, from mid-to-late February each year, the unlikely star of the preserve is Horsetail Fall-a small waterfall that forms over the eastern edge of the park’s famous vertical rock formation, El Capitan, every winter. That’s because, during the two-week-period, the temporary1,000-foot fall frequently transforms into a red “firefall” for about ten minutes a day during sunset.
For the phenomenon to occur, several conditions need to coincide. There must be enough snow and snow must be melted to form the waterfall. During drought years, Horsetail Fall is reduced to a trickle flowing slowly in drops or does not appear at all. Additionally, the skies have to be entirely clear. Even a slight mist is enough to ruin the illusion (错觉) of fire falling down the cliffs. Finally, the sun has to strike the water from the right angle to set the waterfall “burning” brightly.
The “firefall” has been popular with professional and amateur photographers since the 1940s.However, in recent years, thanks to social media, its fame has risen to new heights, with thousands of people flocking to the national park each February. In 2019, over 2,200 people crowded into the small viewing areas on February 22, the best day to see the light show last year. However, the visitors not only stepped on sensitive vegetation but also left behind large amounts of rubbish.
To prevent a repeat of the unfortunate incident, in 2020, the park service closed two of the ideal viewing areas. The only one open required a 1.5-mile-long hike. However, the 3-mile round-trip, as well as a warning by the officials that a dry spell turned the fall into a trickle, leaving the possibility of a “firefall” in doubt, didn’t not seem to have deterred fans. Hundreds of people made their way to Horsetail Fall to catch a glimpse of the light show. Hopefully, Horsetail Fall enthusiasts would be more respectful of the natural environment this time.
1.When can the “firefall” be seen?
A.About at dawn.
B.Exactly at noon.
C.Just before dusk.
D.Late at night.
2.Which of the following conditions must be met for the “firefall” to be visible?
A.The temperatures have to be warm enough.
B.Horsetail Fall must be reduced to a trickle.
C.There has to be enough slight fog in the sky.
D.The waterfall must be frozen down the cliff.
3.What do we know from Paragraph 3?
A.The “firefall” was discovered by a photographer.
B.The viewing areas were equipped with telescopes.
C.Social media offer new tools to view the “firefall”.
D.The tourists caused the environmental pollution.
4.What does the underlined word “deterred” in the last paragraph mean?

C.Disturbed. D.Distinguished.
Peter and Cheryl Pitzer met in 1999. After training together, they fell in love and finally married in 2011. The Pitzers have been using their professional aviation skills to help people around the world regain sight. They are both volunteers for Orbis, a non-profit organization that turns airplanes into teaching hospitals and brings eye care and ophthalmology (眼科学) training to places around the world. The organization’s Flying Eye Hospital that the Pitzers fly together is an ophthalmic teaching hospital on board an MD-10 aircraft.
The Pitzers flew their first flight together with Orbis in November, a journey that took them from Dubai to Saudi Arabia and finally to Ghana, a country in West Africa. The couple stayed an extra week after landing the plane in order to be on the ground to help other Orbis volunteers treat people in need, and to train medical staff in the community. “There was a woman named Mary. When we met her on Monday she was almost completely blind and when we left she could see,” recalled Peter.
“They also did surgeries in the local hospitals with the local doctors and their equipment, and they provide continuing education afterwards,” Cheryl said of the team’s work in Ghana.“The idea is to leave the knowledge behind so that people will have access to proper eye care after the plane is gone.”
The couple say they are grateful to share an occupation that they love-one they can do together and that allows them to give back. “It's awesome to see so many people in poverty regain sight. Our work is worth it,” said Peter. “Cheryl and I have a great personal and working relationship. It's just an interesting and incredible way to give back.”
Cheryl noted the intense (紧张的) planning and coordination it takes to fly a major plane carrying a teaching hospital to remote locations. She said she and her husband have an advantage with that complex task because they “understand each other.”
1.What are Peter and Cheryl Pitzer by trade?

B.It is a modern general hospital.
C.It is a private hospital in Dubai.
D.It is a famous hospital in Africa.
