There is an ancient Chinese story about a giant man named Kua Fu who chases the sun. He drains (喝干) the Yellow and Wei rivers during his race and finally dies of dehydration(脱水). His failure has reminded people of the unstoppable power of the sun for centuries. And yet, scientists throughout history have tried to better understand the most important star in our sky. On Aug 12, 2018, NASA launched the Parker Solar Probe(探测器), marking the start of its trip to the sun.
The probe itself is almost as big as a car and needed the help of a powerful rocket to escape Earth's orbit, change direction and reach the sun. In order to reach the sun, the probe must complete seven flight of Venus, using the power of the planet's gravity to change its path, sending it toward the sun. But that's not the only difficult part of the journey. As the probe approaches the sun's corona(日冕), it will have to bear temperatures reaching 1,400 C, as well as deal with serious radiation. So how will the probe survive?
According to NASA, a special shield (保护罩) has been used, which is a special 11.5 cm-thick carbon-composite shield that will be positioned between the probe and the sun's corona. Its advanced technology like this will make the probe's trip to the sun much smoother. If everything goes as planned, the probe will reach a speed of 692,018 kilometers per hour as it orbits the sun, setting a new record for the fastest man-made object in history, NBC noted. It will fly close to the sun 24 times between 2018 and 2025, NBC added.
The "mission to touch the sun" will "not only make history by answering questions that have puzzled scientists for decades, but it may also lead to the discovery of new phenomena that are completely unknown to us now," Raouafi told Discovery Magazine. "This mission has the potential to push solar research into a new direction," he added.

2.What do we know about the Parker Solar Probe?
A. It’s the fastest probe ever designed.
B. It has an 11.5-inch-thick shield.

D. It’s twice the size of a car.
3.The probe will meet the challenges except ________.

C. the distance to the sun D. the radiation from the sun
4.What’s the main purpose of the last paragraph?
A. To stress the importance of advanced technology.
B. To prove the mission is the greatest move in human history.
C. To suggest there is a long way to go in solar exploration.
D. To show the mission will fill a gap in solar research.
How old is too old to go trick-or-treating? Chesapeake of Virginia says the answer to that question is anyone over the age of 12.
City officials recently announced that doorbell-ringing candy seekers over the age of 12 could face a charge, up to six months in jail, and $25 to $100 fines. They're far from alone. Meridian of Mississippi, Bishopville of South Carolina, and Boonsboro of Maryland, also have set the age at 12. The phenomenon isn't limited to the US: In 2017, Bathurst, a town in Canada, banned anyone older than 16.
Officials say they won't be actively looking to catch teenage trick-or-treaters in the act. The age limits are part of a broader push to limit pranks and tricks. Some parents think that preventing older kids from participating in Halloween traditions will have the opposite effect. A Facebook post last year argued that all kids, regardless of age, should be allowed to take part in trick-or-treating. It was shared more than 4,000 times, with close to 700 comments.
Some parents argued that kids shouldn't be spoiled. Others argued that even older kids should be encouraged to take part in it in the sense of wonder and excitement, and most said they were willing to give candy to whoever dressed up. That seems consistent with the scientific studies that play is essential to help children develop into healthy, well-adapted people, and that play encourages kids to develop collaboration and creativity.
Given how over-scheduled, anxious, and unhappy today's teens are, maybe a little Halloween magic is exactly in order.
1.How many American cities that have set the limit of going trick-or-treating are mentioned?
A. One city. B. Two cities.
C. Three cities. D. Four cities.
2.Why did the officials decide to prevent teens from going trick-or-treating?
A. Because the teens are too old to go trick-or-treating..
B. Because it is thought that the teens will do something harmful.
C. Because some parents are afraid that kids can be spoiled.
D. Because that seems consistent with the scientific studies.
3.What may most people agree with according to the passage?
A. All people should take part in the Halloween traditional activities.
B. Halloween tradition is no longer as attractive as before.
C. It's not a good idea to limit the age of going trick-or treating.
D. Play is necessary to help children develop into healthy and well-adapted people.
4.What is the author's attitude towards the age limit of going trick-or-treating?
A. disapproving B. objective
C. favorable D. indifferent
