Read the following article and answer the question. Article: As children begin to head back to school, there are several things that you can do to make sure that your child stays healthy and performs at their peak potential during the school year. 1. Make sure your child is up to date on their immunizations . The summer is a good time to schedule visits to the doctor's as your child is not in school, and the visit won't require that your child miss school days. 2. Encourage proper nutrition. America faces childhood obesity . This means that the percentage of overweight children is increasing each year, and this will place your child at risk of developing a variety of diseases when they are middle age or even young adults. You can start helping your child to become healthier by offering fruits and vegetables at home instead of calorie heavy potato chips and candy. 3. Get your child involved in sports activities. Activities in high school such as track and cross-country are important for socialization for your child, as well as helping to improve their health. You can get your child interested in wholesome activities by discussing with them how you enjoyed similar activities in high school. 4. _ . Many children become sexually active in junior school and senior high school, and the sooner you discuss sex with your child the sooner they will be prepared. Tell your child that there is always the possibility of infecting a sexual disease when two people have sex; and discuss with your child the use of condoms. The sooner you start having this embarrassing situation the better. 5. Know your child's friends. You can do this by inviting your child to bring their friends over to your house for a pizza night, or by chatting with them when they stop by your house. If you find your child's friend has a bad reputation, then you could consider introducing your child to a different network of people, such as through the girl/boy scouts. Forbidding your child from seeing a certain person may only lead them to rebel and become closer to that person. 6. Discuss with your child the...

Read the following article and answer the question. Article: I do a lot of hiking.And I can step out of my house and within minutes reach a beautiful forest where I walk for exercise every day.I see many photography subjects such as parrots,snakes,hares,big trees and flowers.There are so many different flowers around my place that once I decided to see how many types I could count in a onehourlong walk,and I counted over 100. Needless to say,as a keen amateur photographer,I always take a camera with me.I have three favorites: a Pentax Optio RZ10,a Sony Alpha 390 and a Panasonic Lumix FZ100.I mostly take the Pentax pocket camera with me.This Pentax pocket camera takes images as good as those from much more expensive Single Lens Reflex cameras.It allows you to get to just 1 cm from the subject,and these images are of astonishing clarity .I can stick the camera right into a flower.And the photo shows fantastic details. The Pentax is also good at taking landscapes.The color is natural and price again the details even of distant objects are great.Sometimes,even when I have one of my other cameras with me,I still just use the Pentax pocket camera.About half of all the images on my website were taken with the Pentax. The Pentax takes quality images in poor light and the zoom works well.You have to work hard to get a blurry shot.This is an especially good feature at parties and gatherings.You get fantastic photos of people.You don't have to wait for them to keep still. Keep this camera in your pocket or in the car.It takes up little room;it's light and you'll never regret it! Question: Why does the author walk through the beautiful forest every day? Answer:
He takes exercise to keep fit.

Read the following article and answer the question. Article: Europe's deadly outbreak of a rare form of E. coli bacteria   has brought new attention to food safety issues. One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick? Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways. Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants  like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines  of humans and many animals. Most kinds of E. coli are harmless but some can make people sick. The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers. Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team. MOON KIM: "We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample." The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit. Moon Kim says the team hopes the system will be available before long. MOON KIM: "We are targeting for development in commercial plants for the next several years." The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface. Question: What is the main topic of the text? Answer:

Answer: A high-tech scanner.
