Children know that summer is probably the most fun of all seasons. However, experts say it is also the most dangerous, especially, for children aged 14 and under. In its first study of children's safety in the US, the National Safe Kids Campaign (NSKC) found that nearly half of the injury-related (与受伤相关的) deaths among children happen in summer.

    Experts are not surprised by the study’s results. They always know summer is a dangerous season for children. During the summer, children are out of school and spend more time outdoors. They are more likely to get into an accident or be injured. "While we encourage children to be active and spend time outdoors, they need to understand the importance of safety," said Everett Koop, an expert of the NSKC.

    To help children stay safe, the NSKC started a "Make it a Safe Kids Summer" Campaign (运动) during National Safe Kids Week, from May 5 through May 12. Here are some important summer safety tips from the NSKC:

● Always wear your seat belt.

● Make sure there is an adult around when you decide to go swimming.

● Wear a life jacket (救生衣) when on a boat or doing water sports.

● Obey all traffic laws.

Money, jewels and important documents may not be the only valuables placed in banks these days. Some mothers store their breast milk (母乳) in banks.
There are ten breast milk banks across the United States, where mothers can donate their extra milk for other women’s babies.
Experts say breast milk is the best food for babies. The World Health Organization says it is the only food babies should get during the first six months of life, in most cases. Breast milk is especially important for babies born too early. Sometimes these premature babies must stay in the hospital for many weeks.
James Cameron is a doctor who treats newborns at Lutheran Children’s Hospital in Fort Wayne, Indiana. He says breast milk is almost like medicine. Doctor James Cameron says, “The fact is that there are so many different proteins and specialized sugars in the breast milk that the mom’s able to make that help provide immunity (免疫力). It’s very important for the health of the newborn.”
Lucy Baur lives near Fort Wayne. She breastfed both her children and always had more milk than they needed. She wanted to donate to the Indiana Mothers Milk Bank in Indianapolis. But freezing and shipping milk can be costly. Then, a donor station opened near her home.
Milk donations in the United States work like this. Donors must be willing to provide almost three liters of breast milk. They freeze the milk and take it to the station. There, employees warm the milk and mix it with other mothers’ milk. Then, the milk is heated to kill bacteria. After that, the technicians test samples of all the milk to make sure it is safe and healthful. The milk is re-frozen and sent to the main milk bank. The milk bank transports the milk to hospitals to feed premature or sick babies.
Donors are tested for diseases before any milk is accepted. They are not permitted to smoke tobacco, use illegal drugs or drink too much alcohol.
【小题1】According to the passage, which thing can also be stored in banks except money, jewels and important documents?

A Simple Scientific Experiment

We live in a noisy world. Young and old alike are troubled by sounds over which we may have little or no control: car and house alarms, motorcycles, loudspeakers, even movie previews.

We attend rock concerts, weddings, parties and sports events at which the music is so loud that you can hardly hear the person sitting next to you. At home, televisions, stereos and computer games are often turned up so loud that listeners cannot hear a doorbell or a telephone.

As if environmental noise were not enough, now we surround children with noisy toys and personal listening devices that can permanently damage their hearing. A series of studies conducted in 2002 indicated that even moderate (缓和的) background noise can interfere with how they learn language. In fact, children in classrooms on the noisy side of a school had lower reading scores than those whose classes were on the quiet side.

Noise-induced (噪音诱发的) hearing loss can come about in two ways: from a brief exposure to a very loud noise or from consistent exposure to moderate-level noise. Thus, there is much concern about the lasting effects of MP3 players that are turned up loud enough to block out surrounding sound, like street noise. An MP3 player at maximum volume produces about 105 decibels（分贝）— 100 times as severe as 85 decibels, where hearing damage begins.

So, before buying noise-making toys, parents would do well to listen to how loud they are. If the item comes with a volume control, monitor its use to make sure it is kept near the lowest level. Consider returning gifts that make loud noises, or disable the noise-making function. Children who play computer games and stereo equipment should be warned to keep the volume down. Most iPads have a control that allows parents to set a maximum volume.

Avoid taking children to loud action movies. If you do go and the sound seems deafening, ask the management to turn down the volume or insist on your money back.

The League for the Hard of Hearing urges parents to encourage participation in quiet activities, like reading, doing puzzles, making things with construction toys, playing educational computer games, drawing and painting, and visiting libraries and museums.
