1 . A new study has found that ride-sharing services result in much more pollution than other kinds of private and public transportation. Ride-sharing trips also draw passengers away from more environment friendly methods of travel, like public transportation, walking or biking, the study found.
Several studies in recent years have suggested that ride-sharing services like Uber and Lyft can worsen traffic problems in cities. The new study represents an attempt to center on how ride-sharing services affect pollution. Overall, the researchers reported that ride-sharing trips now "result in a 69 percent more climate pollution on average than the trips they replace." The study notes that the same passengers could have chosen to travel by bus, train, bike or on foot.
One of the big reasons they give for this result is that ride-sharing vehicles are often driven with no passengers in the car. This happens when drivers are either waiting for rider requests or on the way to pick up passengers. This situation, known as "deadheading", takes up about 42 percent of all ride-sharing driving activity, the study found. The researchers said that deadheading results in about 50 percent more carbon dioxide than one person driving in a private vehicle. Both Uber and Lyft have said in the past that most studies on the subject overstate (夸大)the effects of their services on pollution. Uber told Reuters news agency in a statement it had no comment on the latest report and that the study made misleading claims about ride-sharing. Meanwhile, the company said it would work directly with cities to address climate changes, promoting sharing trips and other means of transportation.

2 . After an earthquake most survivors can be expected to recover over time, particularly with the support of family and friends. Some families will be able to return to their normal life quickly, while others will have to contend with the destruction of their homes, medical problems, and injury to family members. Children especially will need time to recover from the loss of a loved one or a pet or from the closing down of their school.
Children often turn to adults for information, comfort and help. Parents should try to remain calm, answer children’s questions honestly and remain understanding when they see changes in their children’s behavior.
Children react differently to an earthquake depending on their ages, developmental levels and former experiences. Some will respond by withdrawing (不与人交往), while others will have angry outbursts (爆发). Parents should remain sensitive to each child’s reactions. Parents should spend time talking to their children，letting them know that it’s OK to ask questions and to share their worries. Although it may be hard to find time to have these talks, parents can use regular family mealtimes or bedtimes for them. They should answer questions briefly and honestly and be sure to ask their children for their opinions and ideas. Issues may come up more than once and parents should remain patient when you answer the questions again. For young children, parents, after talking about the earthquake, might read a favorite story or have a relaxing family activity to help them calm down. Parents should also tell children they are safe and spend extra time with them. They could play games outside or read together indoors. Most importantly, be sure to tell them you love them.

3 . Kevin Randall, a teacher,who teaches biology at Grandville High School,runs the environmental club at the high school,which has around 2,000 students.The club is known as the GHS Green Team,and it aims to raise awareness among students and teachers about sustainability(持续性).It also works on projects to reduce the environmental footprint of the building itself.
One of the club's recent projects focused on reducing waste in the school cafeteria.Randall said their cafeteria supervisor told them that the school went through 54,000 plastic forks every year.The club applied for a financial help,built recycling centers for the cafeteria,and purchased metal silverware.
And now every student uses a durable metal fork or a spoon instead of disposables.(一次性用品),“and that's just one way we're trying to capture the low-hanging fruit,if you will,"Randall said.
The efforts of Randall and his students have earned Grandville High School the Michigan Green School certification from the state.In addition to their work reducing waste in the cafeteria, the GHS Green Team has also built a garden with flowers and vegetables on campus,and leads cleanups on site and out in the community.Over the years,Randall and his students have also been working on raising money to install solar panels(太阳能板) on the roof of the high school.
Randall said he was motivated to take the lead on environmental issues for his school because he wanted his students to have someone to turn to in the building who understands what's at stake(利害攸关）when it comes to climate change.
＂And I also felt like I needed to do more in my life for my own two children at home," Randall added,"They need to know that their dad is working as hard as he can to reduce the effects of climate change,and to spread the word,and to make sure that other students out there are learning about this just the way they are at home."
