mean its heading for Earth’s vicinity（周边）, passing within 3,908,791 miles of our planet.
Officially classified as 52768 (1998 OR2), the near-miss has been predicted to occur on April 29. According to NASA, the asteroid is traveling toward us at 19,461 miles per hour and is about half the size of Mount Qomolangma.
The space agency first discovered the object in 1998 and said it would be “large enough to cause global effects” if it were to hit Earth. But despite being classed as “potentially hazardous （有危险的）”, scientists said it is not on the list of potential future Earth impact events.
Currently, the agency has identified 20,000 Near-Earth Objects. Of these, only a few are considered potential impactors, which NASA tracks via their automated Sentry System.
The near-miss 1998 OR2 might not pose a threat, but many scientists agree it’s only a matter of time before a huge asteroid collides with Earth.
Cardiff University scientist Ian McDonald told BBC Today, “Doomsday asteroid hits aren’t confined to the past. There are always rocks flying through space. One of these will hit us and it will have pretty dramatic effects.”
The last Earth impact was in 2013, and terrifyingly nobody saw it coming. Dubbed（被称为）the Chelyabinsk meteor, it exploded just 30 kilometers from Earth’s surface, shattering windows and rocking buildings for over 500 square kilometers, according to the BBC.
This impact injured around 950 people in Russia, but it just goes to show how precarious life on Earth is and how it could be devastated（毁坏的）by larger future impacts.
8. What can we learn about 1998 OR2? A. It is as large as Mount Qomolangma. B. It is heading for Earth at 3,908,791 mph. C. It is likely to occur at the end of March. D. It is estimated not to be a threat to Earth. 9. What would McDonald probably agree with?
A. There is little chance that the doomsday asteroid hits Earth. B. A mega asteroid could unavoidably threaten Earth one day. C. Potential impactors could be tracked and destroyed.
D. Mega asteroids could collide with Earth more often in the future.
10. By mentioning the Chelyabinsk meteor in the text, the author intends to________. A. compare it with the upcoming 1998 OR2 B. present the dramatic effects of Earth impacts C. show how frequent Earth impacts are
D. prove that little can be done in the face of an Earth impact
11. The underlined word “precarious” in the last paragraph probably means “_________”.
A. uncertain B. unprepared C. precious
D
A couple of weeks ago, my grandfather was explaining his favorite expression, “Nothing is ever easy.” The following day, as I tried to complete my day’s work, I happened to notice a bumblebee（大黄蜂）on the skylight（天窗）. The skylight was
D. diverse
particularly high up, but I thought removing the bee would take no more than five minutes. An hour later, the bee still remained. All that had changed was that the living room was a mess and that I was dizzy from looking up into the sunlight. I did not expect to waste an hour on an insect so tiny, but by doing so, I understood what my grandfather meant.
It is not only time that we tend to underestimate — we don’t account for unexpected costs. We often imagine what can work in our favor, but we seldom think of all the negative things that could affect us. However, it is important to remember that your day or week or year might not go as planned, and that is completely normal. It is perfectly acceptable to feel challenged — even at a task you thought was simple — because that is part of life.
If you can accept that nothing will ever be easy, then life might seem slightly more manageable. In middle school, I thought high school might be easier because I could choose the classes I wanted to take. In high school, I thought college might be easier because I could have a schedule best suited for myself. Yet each time, I was both wrong and disappointed. After accepting that school wouldn’t (and shouldn’t) be easy, I found myself with a more positive attitude and improved results.
Of course, there should be preparations made to account for expenses or time. Doing so can only help you accomplish your goals in a better way. However, there is no need to beat ourselves up（过分自责）when something stands in our path. Maybe we cannot see a bee coming our way, but we can always give ourselves the extra time to catch it.
12. Why did the author mention his experience of removing a bee? A. To share something unforgettable with us.
B. To lead us to what the author learned from it. C. To show the unexpected costs it caused. D. To tell us how easy it is to waste our time.
13. Why do things often turn out to be different from what we expect? A. We often don’t take time seriously. B. We tend not to have enough money. C. Unexpected things can happen. D. It is easy to feel challenged.
14. Why did the author mention the “bee” again in the end? A. To show how annoying it is. B. To tell us we need to catch it. C. To link back to the beginning. D. To use it as a representative of luck.
15. What is the author’s purpose of writing this article? A. To encourage people to make greater efforts. B. To explain how to make preparations.
C. To tell us what to do when something gets in our way. D. To persuade us not to expect things to be easy.
