5 . A bull bison(野牛)in Yellowstone National park charged at a 9-year-old Florida girl. Luckily, the girl was left with only relatively minor injuries. Eyewitnesses say that a group of around 50 people—including the unidentified girl—were standing within 5 ~ 10 feet of the bison for at least 20 minutes near Observation Point Trail before the animal decided to charge. "We saw through the trees some people petting the bison, super close,” Hailey Dayton, 18, an eyewitness who filmed the incident. " Because it was agitated by all the people and noise, it just attacked.''

In Yellowstone, there are about 4 ,500 bison, the nation's largest and most important bison population on public land. Yellowstone is the only place in the lower 48 states where free-ranging bison have lived continuously since prehistoric times, according to a statement from the National Park Service (NPS). The Yellowstone population is also significant for being one of the few herds(群)in the country that has not been inter- bred(杂交)with cattle.

While they feed primarily on grass, they can be aggressive if annoyed. " Stay 25 yards away from all large animals—bison, bighorn sheep, deer etc. —and at least 100 yards away from bears and wolves," the statement read. " If need be, turn around and go the other way to avoid interacting with a wild animal in a close distance. ”

Despite the presence of seemingly more dangerous animals such as bears and wolves, bison have injured more people in Yellowstone than any other creature. "This is what happens when you make fun of wildlife and pay no mind to an animal's personal space,'' Dayton wrote in a tweet. " This family was petting the buffalo before it charged. And as you can see the parents saved themselves over their daughter. That really put me off. ”

People love the view of old buildings in Paris, especially Notre Dame Cathedral(巴黎圣母院).     1    (unfortunate), on April 16, a fire destroyed the spire(尖顶) of the 850-year-old cathedral, and two-thirds of the roof. Flames could be seen     2    (rise) through the top of the monument. The citizens in Paris gathered around the cathedral, praying     3     the hundreds of firefighters who fought the flames.     4     was no wonder that people felt sad. The church itself, after all, is a historical and artistic treasure.     5    (build) in 1163, it is one of the world's most famous tourist sites, attracting about 12 million     6    (visit) every year.

Notre Dame Cathedral is home to many     7    (religion) artworks, paintings and sculptures. Despite its long history and many treasures, the cathedral     8    (need) the help of a writer to become truly famous. Victor Hugo's 1831 novel, The Hunchback of Notre-Dame, presented the building to     9     wide audience of readers. He wrote the book to remind people of it, with the hope     10     they would protect the beautiful old buildings of Paris.

My friend Lilly and I were on the way back to home from school when we saw a boy fall off his bicycles. The boy lay on the ground， screamed in pain. We rushed to help and found if the boy's left leg was bleeding. It happened that we have learned some knowledge about first aid before， so we knew how we should do. We dialed "120" and called an ambulance. While waiting it， I took out my handkerchief and pressed them onto the bleeding point. Then we rolled the boy onto one side but put him in the recovery position. We stayed with him until the ambulance arrived 5 minutes late.

8 . The sound that woke Damian Languell at 8:15 in the morning was so loud he assumed it came from inside his house in Wade, Maine. As he got up to investigate, he heard another sound, this one coming most definitely from outside. Looking out of his bedroom window, he noticed a tree enveloped in smoke about 500 yards away. A car wrapped around the tree's base, its engine on fire.

Grabbing buckets of water, he and his wife ran to the crash site. Up close, the accident looked worse. The car was split nearly in two, and the tree was where the driver's seat ought to have been, as if planted there. No one should have survived this crash, and yet there was 20- year-old Quintin Thompson, his terrified face pressed against the driver's side window, in visible pain.

Languell tried putting out the fire with his buckets of water but failed. When the flames got into the front seats, he knew he had to get the young man out. So Languell opened the car's back door and climbed in. Using a pocket knife he'd brought with him, he cut through Thompson's seat belt. Now that Thompson was free, Languell pulled him out, and dragged him to safety before the entire car was in flames.

It is empathy that drove Languell to help, just as he said, "My heart goes out to Thompson. When you are that close to that level of hurt, you feel it so directly." For his heroic action, Languell was added to the list of real-life heroes changing the world.
