The cook put a cheeseburger (奶酪汉堡)and an applesauce cup on his tray. He grabbed a bottle of milk from the cooler at the end
3、of the line and found a seat in the cafeteria (食堂). Ryan saw that his friend Tyler had brought lunch from home. “What did you bring today, Tyler?“ he asked. Tyler pulled his meal out of its brown paper sack. “Ive got a ham sandwich, chips, two cupcakes, and a can of soda.“ Ryans mouth started to wat
4、er. “Uh, Tyler,“ he said. “If you dont want one of those cupcakes, Ill take it. They sure look good. “ Tyler handed Ryan his cupcake. “Sure,“ he said. “I wont eat all this.“ Lunch Requirements Is Ryan eating a healthy meal if he eats the school lunch? School lunch supporters say “Yes.“ Recent studie
5、s show that a government-approved school lunch has more variety and is more nutritious (有营养的) than most lunches brought from home. Its also lower in fat. The National School Lunch Act requires that school lunches go along with the Dietary Guidelines for Americans developed by the government. Meals m
6、ust contain a variety of foods with plenty of grains and at least one fruit or vegetable each day. Foods must not contain too much sugar or salt. A hot lunch can contain up to 30% fat, but not more than 10% of its calories (卡路里) should come from saturated (饱和的) fat. In an average week, you should ge
7、t one-third of the daily Recommended Dietary Allowances for protein, iron, calcium (钙), and vitamins A and C from your school lunch. Dare to Compare Lets compare Ryans and Tylers meals to sec which is healthier. Ryans hot lunch (without the cupcake from his friend) has 577 calories, 25 grams of tota
8、l fat. and 12 grams of saturated fat. He had one serving of fruit, 26 grams of protein, and 483 milligrams of calcium. Ryan ate more total fat (39%) and saturated fat (19%) than the dietary guidelines recommend. However, schools can still meet the guidelines by having the numbers average out over a
9、week of lunches. Tylers lunch from home (this includes both cupcakes) had 1 014 calories. 45 grams (40%) of total fat, and 10 grams (9%) of saturated fat. He ate 21 grams of protein and 155 milligrams of calcium, but no fruits or vegetables. Tylers meal met the saturated fat guidelines, but had too
10、much total fat. Tyler ate more calories and total fat than Ryan did. Ryan ate more protein, calcium, and fruit than Tyler did. Which meal would you say is the healthier choice? la Carte Options Federal standards and most school districts forbid selling food in the cafeteria that competes with the sc
11、hool lunch. Many programs do, however, offer la carte choices for students who dont want the hot meal. Foods sold la carte separate from the main meal and are priced individually. These foods do not have to meet the same nutritional standards as the foods on the hot lunch menu. Neither do the foods
12、sold at a snack-bar or those foods available elsewhere in the school. A study in one Texas school district compared the lunches of fourth graders who did not have food choices with those of fifth graders who could choose either a standard lunch or select from a snack-bar. The fourth graders ate 25%
13、more fruits and vegetables than the fifth graders. Food sold as fund-raisers can also have an impact on school lunch. The money raised is important to provide needed funds for many after-class activities. But the meals overall nutritional quality usually goes down. Many of these foods are high in fa
14、t, sugar, or both, and often come in extralarge portions. Fundraisers rarely sell fruits and vegetables. Choosing Wisely School food-service programs are trying to please students, and still offer quality, nutritious meals at low cost. That task isnt easy. One school district in New York decided to
15、do something about it. A student advisory board kept the food-service director up-to-date on what the kids wanted. They also worked with school snack-bars to sell smaller servings of chips and candy. You can make healthy meal choices at school even when not-so-healthy choices are available. You can
16、be sure to get a nutritious meal when you pick foods from the Food Guide Pyramid. For example, always drink milk or a calcium-rich juice for lunch. Even chocolate milk is more nutritious than soda or a sports drink. Stay away from snack foods offered la carte. They may fill you up now, but the ones
17、that contain a lot of fat and sugar will slow you down later. Always eat the fruits and vegetables offered at the meal. They help give you the energy and vitamins you need to get you through the rest of your school day. Some people like to make fun of school lunches, but good nutrition is no laughin
18、g matter. Your schools hot lunch is based on the Food Guide Pyramid, so its full of nutrition. Give it a try. You might be pleasantly surprised. Its a Team Effort Team Nutrition is a program that gets schools excited about healthy eating. Schools across the nation pick a team leader who develops fun
19、 nutrition activities. The leader works with students, teachers, parents, food-service workers, and people from the community. Activities can range from running a school health fair to planting a garden. At the Jordan Community School in Chicago, Illinois, one group of fifth graders showed off their
20、 “pizza (比萨饼) garden“ in a big, colorful poster showing vegetarian pizzas. The students and foodservice staff planted and took care of the vegetables that they would later use as ingredients on their pizzas. The group started growing the plants in the schools cafeteria. Then they moved them outdoors
21、 to the students demonstration garden. This is just one way to get everyone involved in making school lunch healthy and fun. Team up with your own group and see how creative you can get.（分数：71.20）(1).What did Ryan do when he saw Tyler?（分数：7.12）A.He compared his lunch with Tylers.B.He offered to shar

Will his future brothers or sisters have a higher risk of _47_ it, too? According to the largest study of siblings (兄

Among 664 children who had at least one older sibling with the developmental disorder, the _48_ risk of autism was nearly 19%, _49_ higher than previous sibling-recurrence estimates that were anywhere from 3% to 10%. Kids with more than one older autistic sibling had an even higher risk of the disorder: 32%. The _50_ suggest that genes play a key role in autism risk. But they also hint that other environmental factors _51_ by siblings, like influences in the womb (子宫), may be important as well. On the _52_ of
