“The noise made by boats of whale watching tourists may be causing communication problems for the animals, "British researchers said last week.
Whale watching is a popular tourist activity in places where groups of killer whales (虎鲸）live. Every day, dozens of boats filled with tourists go to watch the beautiful animals. Unfortunately, the engines of the boats make a lot of noise，and that may cause problems for the whales, according to a report in the US science magazine Nature.
The whales travel in groups, and communicate with each other through sonic (声波的）calls that some scientists refer to as singing. The sounds of the boat engines may be creating too much background noise for the whales to be able to hear each other.
The researchers listened to recordings of whale calls made between 15 and 25 years ago, before whale watching became popular. These were com-pared to more recent recordings.
They found that the animals have started to sing for longer than they used to, like a person shouting to a friend across a noisy room.
It is believed that the whales are trying to communicate hunting or breeding (繁殖）information. Scientists said that, if this is prevented, the future of the world's whale population could be in danger.
"Animals become slow in mind and repeat them-selves in noisy areas，" said Volker Deecke , a Canadi-an biologist. “They have to say things twice or three times in order to be understood. ”

How difficult change is depends a lot on your attitude towards it and your resistance to it. Your attitude to change can make the whole transformation process much easier.
Imagine change as a pair of shoes and this will help you understand change and how it works. I am sure that you have ever had a comfortable pair of shoes in your life. A pair of shoes is so comfortable that you really don’t want to get rid of them.
You know you need a new pair, and may even have them, but you don’t want to wear them because you are comfortable with your current pair. Besides, the new pair may hurt your feet, give you blisters(水疱) or be awkward to wear to start with. So, you resist the new shoes. However, you know that this new pair would be much better for your feet, and after the initial discomfort they would probably be even more comfortable, yet you still resist.
Do you know I’m doing this now? I’m wearing my comfortable shoes and they feel good. They have a hole in each heel, and the sole is starting to fall off, but I’m persisting in wearing them.
This describes change exactly; change of our habits, change of our thought patterns. We stick with the old patterns because they are comfortable. Yet once we get over the initial pain of the transformation, the new pattern will be comfortable and feel good until the time comes when we need another new pair of shoes.Why do people prefer old shoes to new ones?
| A．They have much emotion in the old ones. |
| B．They are more comfortable. |
| C．New shoes always harm the feet. |
| D．They look better than the new ones. |
According to the passage, we know that people ______.
| A．don’t realize the benefit of the new shoes very well |
| B．are positive and open-minded to accept new things |
| C．actually know the change will finally be good for them |
| D．don’t accept new patterns because they are not good |
What can be inferred from the passage?
| A．Once we form a habit, it’s difficult to change it. |
| B．Most people pay more attention to the future life. |
| C．One’s attitude towards something is usually traditional. |
| D．The more often we change, the better our life will be. |
It was the first day of second grade, and Sarah had been looking forward to this moment. The night before, she laid out her favorite clothes: a white coat and a bright yellow shirt.
When having breakfast, Sarah dropped some food on her shirt, so she had to change into her second-best clothes, blue jeans and a Jonas Brothers T-shirt.
After breakfast Sarah rushed to catch the school bus and when she was just reaching the door the bus driver opened it. The door hit right in Sarah’s face and blood dripped from her nose. The driver wanted to send her home, but she refused, "It is the most important day of the year! I can’t miss it!"
Before classes, Sarah went to her favorite swing. When rising high, she saw her best friend little Jack. She let go of the swing and waved to him with one hand. Unfortunately, she flew out of the swing and landed hard on the sand, breaking a leg and an arm. As she lay in the sand, she noticed a shiny thing on the ground beside her. With her good hand she took it.
When Sarah’ mother rushed into the ward she was surprised by what she saw: her girl was lying in bed with an arm and a leg in the splint (夹板), a broken nose, and blood stains on her second-best clothes.

Parkour (跑酷) is a new sport that is developing quickly in the world. The aim of parkour is to jump, climb or run over any all stair, or fence on your path easily. Usually, it is done in a city environment. Practicers take very wall or roof as their training place. If you have seen the beginning of the James Bond movie Casino Royale, then you have seen an excellent example of parkour.
David Belle, a young Frenchman, developed parkour in the 1990s. His father's experiences as a fireman as well as an acrobat(杂技演员)influenced him a lot. His childhood friend, Sebastien Foucan, is the actor in the movie Casino Royale with his parkour performance. Foucan is thought to have developed free-running, which is a more artistic and skillful type of parkour. David belle traveled to India and said one way he trained was by watching a physical one. The aim is to become so skillful, and it is almost unnecessary for you to think about the different actions in running through a path full of barriers(障碍物).
Parkour is not exactly a sport. It is not developed fro competition. It is more about learning to control mind and body in difficult situations. There are many basic movements in parkour. One example is where practicers swing through the narrow space between two bars while keeping their body level with the ground. This is called the underbar. Other movements are the tic-tac and the kong vault jump. Skillful practicers seem to get out of control of gravity.
The popularity has spread largely because of parkour videos and organizations on the Internet. And if you search on the Web, you will find parkour groups performing their skills near you.The author wrote this text to _______
