Countries around the globe are spending billions of dollars and lots of time on various space missions. 1. Instead, we should feed the world’s poor and find immediate solutions to other problems. However, others feel this is a shallow view which fails to realize how exploring space helps us.
2. It has directly resulted in the many satellites that now orbit Earth. A number of the satellites record data on land and weather patterns. 3. After careful analysis, the scientists can provide useful recommendations and advice for farmers.
Space exploration has already promoted technological improvements that benefit us all. High-end products around the world are made to a higher standard. Today space technologies are widely used in all kinds of industries. 4.
Sending astronauts into space has helped people think about the world’s problems and find ways to solve them. Our planet’s resources are limited. In order to provide for the rapidly increasing population, scientists are trying to find other planets that could one day be our new home. 5. In the future, humans may live on both planets.

As the novel coronavirus outbreak interrupts businesses and everyday life for billions around the globe, massive conferences have moved online. The new form creates numerous technical and organizational challenges, but it also offers opportunities-for reaching wider audiences, reducing the carbon footprint of meeting travel and improving diversity. For some meetings, the switch may be lasting.
The scientific community is “ making lemonade out of lemons,” an expert says. “ Scientists are making use of a situation that’s really quite horrible and providing people a way to connect.”
In many ways, virtual conferences offer a better experience, says Altman, associate director of the Stanford Institute for AI. Altman’s institute had planned an inperson conference in April, but COVID-19 forced organizers to change it. They threw together a virtual conference to discuss how AI can help scientists fight the ongoing pandemic (流行病).The event was a great success. The original conference would have drawn a few hundred attendees, but 30,000 people watched the online version.
Altman says the virtual environment allowed hosts to better control the flow of discussion and questions from the audience. By privately messaging one another behind the scenes, they were able to make adjustments (调整).During the audience question period, the hosts didn’t open up the virtual floor for anyone to speak. Instead, they asked the audience to type their questions and screen the most insightful (有深刻见解的)ones.
Scientists acknowledge that virtual conferences can’t completely replace the conference experience. Virtual meetings might lose some of their appeal once stay-at-home requirements loosen. Even so, the success of some scientists further strengthens the society’s march toward virtual meetings.

Years ago, I had a falling out with a friend due to a misunderstanding that was completely my fault. I was afraid to admit that I was wrong, so we didn’t speak for years. Then we bumped into each other and decided to meet for lunch. It was so pleasant that we kept meeting. After two or three meals together, I pushed myself to apologize for my fault years earlier.
My experience isn’t unique: Many people avoid apologizing because the idea of admitting to wrongdoing makes them terribly uncomfortable. “We all like to view ourselves as good people- as kind, considerate and moral,” says Ryan Fehr, a professor at the University of Washington’s Foster School of Business.
“Apologies force us to admit to ourselves that we don’t always live up to our own standards. We might also fear that the victim (受害者)won’t accept our apology, further compromising (作出让步；违背)our positive sense of self. For these reasons, an apology can be very difficult to give.”
For many, apologizing is stressful, awkward and uncomfortable. Research shows that it can improve your mental health, repair damaged relationships and increase self-respect.
“Apology acts as a signal of one’s moral character,” Fehr says. “It represents a separation of the offender(冒犯者)from the offense. The offender is saying: “ I recognize that what I did was hurtful, but that offense does not represent me as a person. ”Even if you speak your words not fluently, they will mean a lot. Victims usually do appreciate an apology. ” Fehr says.
I know this first-hand: My friend and I had lunch recently, 15 years after my belated (迟来 的)apology. Admitting that everything had been my fault helped. We’re both appreciative to have our friendship today.
1.What is the purpose of paragraph 1?
A.To tell us the background. B.To present the topic.
C.To describe the misunderstanding. D.To provide some guidance.

A.Lack of chances. B.Shortage of money.
C.Regret and shame. D.Fear and awkwardness.
3.What does the underlined word “they” refer to in paragraph 5?
A.Offenders. B.Victims.
C.Words of an apology. D.Replies to an apology.
4.What does Ryan Fehr think about making an apology?
A.It will give both sides some relief.
B.It means giving up our self-respect.
C.It will make people value friendship.
D.It is no use forcing people to make an apology.
Spaghetti and meatballs is my favorite food. And reading is my favorite hobby. When you are deeply absorbed in a book, you stop paying attention to what’s going on around you. People describe it as being “lost in a book”. It’s a wonderful feeling, but it can be risky.
One day I was home alone doing two of my favorite things: Eating a huge plate of spaghetti and meatballs and reading. At the time, my family had a pet bird, a big white cockatoo named Luke. He was free to leave his perch (栖木)and fly around inside the house. Luke enjoyed “talking” to people, but he wasn’t trained to use real words.
As I was reading and eating, Luke was talking to me, but I was lost in my book. So Luke decided to get closer. He flew from his perch, and before I knew it, he’d landed right on top of my spaghetti and meatballs!
I was so surprised that I didn’t even have time to think. My reaction was the same as yours would be: I shooed (发出嘘声赶走)him off my food! This wouldn’t have been so bad except for one thing: When Luke had landed on my plate, he had grabbed (抓住)my spaghetti with both feet. So when Luke took off again, the spaghetti-still in his feet-went flying everywhere, landing on my shirt and hitting me in the face. Red sauce splattered (泼溅)up the wall and onto the ceiling. As I pulled noodles out of my hair, Luke flew back to his perch, dropping spaghetti sauce all the way.
He wasn’t hurt, except for his dignity-the sauce in his beautiful white feathers turned him orange for several weeks. So next time if you find a spy novel at the library with red, spots on two pages near the middle, you’ll know that I’ve read that book ,too!
