Who hasn't found themselves reaching for the closest food available when they're tired and stressed? More and more research is proving that this isn't all in our mind. Some foods really do lead to a change in our moods (心情)．
Carbohydrate (碳水化合物) for calm
This is how some people medicate(治疗) themselves with food — by reaching for cookies or pasta(意大利面食) whenever they're upset. Unfortunately, it doesn't always work. You must eat a meal consisting of 100% carbohydrate, on an empty stomach, to obtain the serotonin (血清素) increase so that you have a good mood.
To get the wishedfor effect, you must not eat anything for four hours and then eat at least 30 grams of straight carbohydrate. Dry cereal (谷类食品), a piece of bread with jam, or a potato should do_the_trick.
Protein (蛋白质) for power
Of course, sometimes we don't need to be calm and sleepy.Sometimes we need a great deal of mental concentration, so this is when it's important to mix protein and carbohydrate. The protein will prevent the tryptophan (色氨酸) from flooding your brain，and the rise in serotonin(血清素) won't occur.
Why dessert makes us happy
Fat and sugar cause the brain to let go endorphins (内啡肽), which send pleasure signals throughout the body. This would be fine, except humans are not particularly good at stopping at one cookie or cake.
You can also satisfy your sweet tooth by choosing fruit for dessert.
Timing your meals for energy
Blood sugar drops after four hours of going without food, causing a decrease(减少) in energy. Eating usually fixes this within 20 to 30 minutes, but don't suppose that eating more will cause a faster increase in energy.
When you eat has as much of an effect on your mood as what you eat. If you regularly go for a long period of time between meals, rethink your schedule and plan ahead.The underlined phrase“do_the_trick”in the third paragraph means ________.
| A．be extremely smart |
| B．intend to cheat someone |
| C．bring about the desired result |
| D．do something to amuse people |
The function of protein is ________.
| A．to help you keep calm and sleepy |
| B．to make you feel energetic |
| C．to lead you to slowness |
| D．to increase serotonin in your brain |
We can infer from the last two parts that ________.
| A．fat and sugar can greatly help people feel happy |
| B．we humans tend to eat lots of cookies and cakes |
| C．the more we eat, the faster we will gain energy |
| D．what we eat is more important than when we eat |
The main idea of the passage is ________.
| A．eating for a better mood |
| B．eating to make you calm |
| C．eating for more protein |
| D．eating to make us strong |
In America, when the eighth graders leave the middle school, they are often worried about moving to the high school. It is a hard time for them, but it can be an exciting one as well. To make it easier, students need to get familiar with their school.
Even though they’ve done this already in the middle school, it’s still important to find where their classrooms are. Most schools take students to the high school for a visit at the end of their eighth grade year. And, most schools also have a freshman (新生) speech for parents and students before the first year begins. Sometimes the main office will give away a map of the school. This can help students and parents to find different places in the school.
One way to know your high school more and make new friends is to join a club or play a sport. Schools often offer chances to join different clubs and sports. Fall activities begin in August before the first day of school. If you are not interested in sports, there are clubs for any interest, such as drama, dance, chess, photography, community service, etc. These clubs allow students from different grades. By joining an activity, students can find new friendships, not to mention improving their chances in future college applications (申请). The school office will have a list of activities offered at the school and information on how to join them.
What’s more, to have a great start to a high school year, students can write down some of their worries, and ask for help from teachers and school workers.According to the text, most students feel ________ when entering the high school.

Imagine a classroom missing the one thing that's long been considered a necessary part to reading and writing ? Paper. No notebooks, no textbooks, no test paper. Nor are there any pencils or pens, which always seem to run out of ink at the critical (关键的) moment.
A "paperless classroom" is what more and more schools are trying to achieve.
Students don't do any handwriting in this class. Instead, they use palm (手掌) size, or specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student's personal computer.
Having computers also means that students can use the Web. They can look up information on any subject they're studying ? from maths to social science.
High school teacher Judy Herrell in Florida, US, described how her class used the Web to learn about the war in Afganistan (阿富汗) over one year ago.
"We could touch every side of the country through different sites ? from the forest to refugee camps (难民营)," she said. "Using a book that's three or four years old is impossible."
And exams can go online too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book.
A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie Sorrell in Kentucky, US, said she used to give about 900 pieces of paper each week to each student.
"Think about the money and trees we could save with the computers," she said.
But, with all t
his technology, there's always the risk (危险) that the machines will break down. So, in case of a power failure or technical problems, paper textbooks are still widely available (可用的) for these hi-tech students. What does the part of the last sentence in the first paragraph, “run out of ink at the critical
moment”, mean?
| A．Pens may not write well at the critical moment. |
| B．Pens get lost easily, so you may not find them at the critical moment. |
| C．Pens may have little or no ink at the critical moment. |
| D．Pens use ink, while pencils don't. |
In a paperless classroom, what is a must?
| A．Pens. | B．Computers. | C．Information. | D．Texts. |
The high school teacher, Judy Herrell, used the example of her class to show that _______.
| A．the Web could take them everywhere | B．the Web taught them a lot |
| C．the Web is a good tool for information | |
| D．the Web, better than the textbooks, can give the latest and comprehensive (全面的) information |

In American schools there is something called Home-coming Day. Many high schools and colleges with a football team have a homecoming game. This can be the most important event of the year except graduation(毕业) or commencement(授奖典礼) day. Students plan homecoming day for many weeks in advance(预先).
Several days before Homecoming, students start to decorate(装饰) the school. There are signs to wish luck to the team, and many other signs to welcome all the graduates. Many people still come to Homecoming twenty or thirty years after their graduation.
The members of school clubs build booths(摊位) and sell lemonade,apples and sandwiches. Some clubs help to welcome visitors.
During the day people like to look for teacher
s that they remember from long ago. Often they see old friends and they talk together about those happy years in school.

People in the United States honor their parents with two special days：Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible(有责任感的) citizens. They give love and care.
