Over their lifetimes, city trees will likely absorb less CO2 from the air than forest trees. A new study finds that city trees grow faster and die younger than trees in forests. Studies have shown forests readily absorb CO2. But there haven’t been much data on whether city trees grow, die and absorb CO2 at the same rate that forest trees do. So Lucy Hutyra, an environmental scientist, and her colleagues at Boston University in Massachusetts decided to find it out.
To figure out how quickly trees were growing the researchers tracked their diameters (直径) of their trunks from 2005 to 2014. The team focused on red oaks and red maples growing on Boston streets. These grew four times faster than the same species did in a nearby forest. Faster -growing trees absorb more CO2. Over the nine years the researchers have tracked these trees and found city trees absorbed four times as much carbon from the air as the forest trees did. The city trees also, however, were twice as likely to die.
City trees grow faster because they have less competition with their neighbors for light. In a forest, trees tend to grow close together, shading their neighbors. So few may get as much light as they want.
“Street trees also benefit from higher levels of nitrogen (氮气) in rainwater. Nitrogen is an element that helps plants grow. It’s also an ingredient (成分) of the. gas-burning cars’ exhausts. Some street trees also may have better access to water than trees in the country. That’s because the underground water pipes can leak,” says Hutyra.
Shaun Watmough, an environmental scientist, says it’s important to keep in mind that people plant city trees along city streets not just to absorb carbon. The trees also help clean the air, provide shade and make a city more beautiful even if it’s only for decades, not centuries.

Centuries ago, influencing people on a large scale (规模) wasn’t easy for ordinary people. Word of mouth was really the only way to pass on information. Books had to be hand-copied, which took a lot of time and was expensive. When the printing press arrived, many more people could get reading materials. Go back to the present age of the, Internet and social media, anyone’s voice can be heard, and anyone’s face can be seen within seconds worldwide.
If you want to expand your incidence, online videos might be the answer. The online videos are very popular nowadays. Here are the facts: 432, 000 hours of videos are uploaded daily to YouTube. Sitting through all of them would take you 50 years! Also, the number of people watching YouTube has increased by 40 percent every year since 2014. It is said that by 2019, video traffic will be 80 percent of all Internet traffic.
In short, if you’re the kind of person that likes leaving your mark, consider becoming a YouTuber. YouTubers are people who often produce and appear in online videos. Perhaps you have thought that creating and posting videos online isn’t real work. Think again. Weng-ie, a Chinese-born Australian vlogger (博主) has more than 9 million followers. She struggles to be a success. It’s bridging that gap between making videos in your bedroom and actually building a media business.
Companies have offered her paid vacations so she could post photos online. She has to refuse several offers because she is too busy making videos.
Don’t feel like you have to be the next YouTube star in order to get started. Start small. Be patient. Have fun. A lot can be done with just your smart phone, your good idea and, most importantly you. What’s stopping you from using videos to influence the online world?

Lincoln High Calculus (微积分) teacher Anthony Yom has given his students the desire to learn and the will to succeed. While his classes are challenging, the educator does all he can to keep his students invested, combining real-life situations and his lessons to show them the value of their work. He challenges us to the maximum, so we do better on tests, sophomore student Alexis Pong told the Los Angeles Times. One of Yom’s other students, 17-year-old Cedrick Argueta, completed a perfect test paper on the Advanced Placement Calculus exam. Only 12 students in the world accomplished this. As for, all of Yom’s other AP Calculus students, each of them passed the challenging exam.
Yom said most of the praise should go to the kids, though he does go above and beyond his students. However, when he first started teaching at Lincoln High, it wasn’t always smooth sailing. Yom felt nervous about the number of students who were unmotivated and unprepared. Some even attempted to physically threaten the teacher. But he didn’t give in. And he gave up his free time to tutor on weekends and during vacations.
At Lincoln High, 80% of the students are Latino (拉丁裔) and Yom hopes to encourage more of them to take his college prep classes, which are currently dominated (支配) by Asians. “I don’t think the Asian students are any smarter than the Latino students,” the teacher states, mentioning that low Latino participation can be connected to cultural differences and expectations. Fortunately, Cedrick Argueta’s AP Calculus success story serves as the perfect example. “My mother cleans houses,” Argueta reveals. “My father is a factory worker.” But the student would be likely to work for NASA or become a teacher.
What is the key to Yom’s success as a teacher? “This may sound dull, but you really have to love them.” the devoted instructor concludes.
1.What does the underlined word “this” in paragraph 1 refer to?
A.Getting a full mark on the APC exam.
B.Preparing for a key university.
C.Passing the APC exam.
D.Learning very well.
2.Which of the following can best describe Anthony Yom?
A.Kind and smart. B.Proud and rude.
C.Mean and stubborn. D.Modest and devoted.
3.Why did the author use Cedrick Argueta as an example?
A.To praise Cedrick Argueta’s great efforts.
B.To encourage parents to send their children to school.
C.To show Latino students can be clever and successful.
D.To show Cedrick Argueta’s idea is better than teachers.
4.Where is the text probably taken from?
A.A math book. B.A newspaper.
C.A guidebook. D.A sports magazine.
