【題目】
Like visible light, UV rays are energy waves released by the sun, only they cannot been seen. Some exposure (暴露) to those waves can do a body good. For example, ultraviolet B (UV-B) rays tell human skin to make vitamin D. Too much exposure can be harmful, though. Overexposure to UV rays can cause DNA problems, opening the door for skin cancer. Too much sun can also cause painful sunburns.
There are three different types of UV energy waves. They are UV-A, UV-B and UV-C rays. Each type moves at a different wavelength, with UV-A’s being the longest. Rays of UV-C are considered especially harmful to human beings. Fortunately, we have the ozone (臭氧) layer of the Earth’s atmosphere. It blocks out nearly all of the UV-C rays and most of the UV-B ones.
The moon doesn’t have much of an atmosphere, though. Back on the moon, things are more dangerous. Over the years, astronauts have planted six American flags on the moon. Some scientists think that powerful UV rays could have bleached all the colorful flags white by now. For this reason, the moon is a dangerous place to visit without protection.
You might think that astronauts who visit the moon would come home with terrible sunburns. That didn’t happen to Armstrong and his company. Neil Armstrong was a U.S. astronaut and the first person to walk on the moon. These astronauts all wore special spacesuits on their missions. Spacesuits were made with heavy fabrics that block out UV rays.
When Armstrong set foot on the lunar surface, he was wearing a see-through helmet (頭盔) with sun shades that were made of ultraviolet-stabilized polycarbonate. It is a very tough plastic that protects astronauts’ faces from UV rays. A weaker material could put the space travelers at risk for “snow blindness” and other problems. Conditions like these arise when UV rays damage parts of the human eyes.
Sunscreen (防曬霜) defends us from the UV rays that do pass through the ozone layer. However, there’s really no need for an astronaut to put on sunscreen. The risk of sunburn goes way down when astronauts are inside a spaceship. Inside the International Space Station (ISS), for example, there is no need for special suits. Astronauts regularly do their work in nothing but common cotton shirts and pants. To protect them from sunburns, the ISS uses UV-blocking windows. So do most space exploration ships.
【1】From Paragraph 1, we can know ________
A. UV-B is harmful to our bodyB. vitamin D is good for our body
C. UV rays cause DNA problemsD. skin cancer is caused by the sun
【2】The underlined word “bleach” in Paragraph 3 most probably means “_________”.
A. 漂白B. 傷害C. 刺穿D. 吹拂
【3】Armstrong didn’t get bad sunburns mainly because _________.
A. there was no UV-C ray on the moon
B. the moon had an ozone layer like the earth
C. he wore a special spacesuit and helmet
D. he put on enough special sunscreen
【4】According to the last paragraph, we can learn _________
A. sunscreen plays a great role in protecting astronauts in space
B. astronauts have to do their work in special suits in the ISS
C. UV-blocking windows are regularly used on spaceships
D. the risk of sunburns increases when astronauts are in space
【5】What’s the writer’s purpose of writing the passage?
A. To show how astronauts are protected from UV rays.
B. To introduce the first human who walked on the moon.
C. To describe the new technology used in space.
D. To show how we protect ourselves from sunburns.

【題目】
“Why does the chicken cross the road? To get to the other side!”
That’s an old joke in the west, but it came to my mind again when I saw people crossing the road at the intersection of Shaanxi Road and Huaihai Road in Shanghai.
When the traffic light was red, a group of people were waiting for the light to change. Suddenly one man began rushing to the other side of the road. Soon others followed him at the crossing and more people did the same. Just like chickens, they didn’t mind the honking horns(喇叭聲) and kept crossing the road in a mess.
Every year several thousand people are either killed or hurt on the roads in Shanghai. And at least one third of them were jaywalking(亂穿馬路). Jaywalking is very common in Shanghai. It seems that jaywalkers are not afraid of the danger to themselves.
Traffic laws are to keep people safe. So we should obey them, and have good road-crossing habits. When someone starts to jaywalk, we should stop him, and never follow him. That way we can avoid the traffic accidents.
【1】Why did the writer talk of the joke?
A. Set the backgroundB. give an example
C. Play a jokeD. express a pity
【2】Why were so many people dead or hurt on the roads in Shanghai?
A. Be cause they liked Jaywalking
B. Because they didn’t obey the traffic rules.
C. Because someone asked them to cross the road
D. Because there were no policemen on the roads.
【3】The underlined word “intersection” here probably means “ ”.
A. roadB. bridgeC. crossingD. traffic
【4】The writer saw people__________ in Shanghai that day.
A. crossing the road in a messB. waiting for the green light patiently
C. crossing the road with chickensD. hurting each other in the street
【5】How does the writer like what he saw in Shanghai that day?
A. He thinks it’s OK.B. He thinks it’s wrong.
C. He has no idea of it.D. He doesn’t mention it.
