1 . E-bikes are becoming more and more popular. It opens cycling to older people, those with disabilities, people who live in hilly cities where regular cycling requires serious effort.

Three things are needed to make e-bikes popular—a safe place to ride, good affordable bikes and a secure place to park. Safety comes first. For bike lanes (车道) to work, the network has to be continuous, not just forcing cyclists into the middle of a busy street. It should be well protected so that the cyclists won't feel they'll be knocked down by cars. It's necessary to provide good affordable e-bikes to customers either in physical stores or in online stores. Only in this way can people consider buying one as their means of transportation. Parking remains an avoidable problem if we want to encourage more people to ride e-bikes. In Netherlands or Copenhagen, large bike parking lots at train and bus stations encourage varieties of transport. People can easily find bike parking everywhere. This is going to be needed in other cities too for e-bikes to really become a form of transportation.

As a matter of fact, people have found that e-bikes are effective transportation choices. A recent study shows that people who ride e-bikes increase their travel distance from 2. 1 to 9. 2 km per day on average. That is sure to do good to their health. It's also believed that if just 15% of a city’s population turn to e-bikes, it would reduce the carbon emissions (排放) from transportation by 12%.

All of these lead me to conclude that e-bikes are a far better way of dealing with transportation emissions than electric cars. They won't work for everyone, but they don't have to.

2 . On a cold winter day, Don took his dogs, Milo and Duke, out for their usual morning walk at Bark Park. But this peaceful walk was interrupted by Mike, an anxious dog owner who was missing his best friend. His small gray dog, Jackson, had gotten lost somewhere in the park- and he'd already been gone for quite some time. Small dogs don't do very well in cold weather. Knowing that there was no time to waste, Don and his own dogs immediately started searching the park. Unfortunately, Jackson was nowhere to be found.

If Don hadn't had his own dogs with him, Jackson might never have been found in time. Don was about to give up on the search and was already heading back to his car. But as Don and his dogs were crossing the bridge, Milo suddenly noticed something in the water. Thinking that his dog had seen a duck or something else, Don tried to pull on the leash, but Milo wouldn't listen. Duke joined in, and the two dogs insisted that something was going on.

Don looked out across the bridge and saw a small, gray shape struggling in the icy river. The reality of the situation clicked, and Don immediately began running down to the water's edge. Don called 911, but he knew that help wouldn't arrive in time. Without even sparing a thought for himself, the brave man jumped into the water and moved straight towards the terrified dog. Jackson was trapped in ice and barely holding himself above water. Don used his arms to break the ice and quickly pulled the dog into his arms. The two swam out of the water and back onto dry land. Mike was waiting for Jackson and rushed him straight to a nearby vet clinic. It's reported that Jackson didn't suffer any harm from the incident and is as cheerful as ever.
