Life is not easy in senior high school. You’ve got the pressure of studies and exams.
From time to time, you may feel depressed and frustrated. When depression strikes, you have to take measures to fight it. One of the strangest ways to fight depression is to eat salt, scientists have found.
Salt acts as a natural anti-depressant (抗抑郁剂), researchers say. While too much can lead to high blood pressure and heart disease, not enough can cause “psychological(心理的) depressions”, a study has reported.
The study, by researchers at the University of Iowa in the US, discovered that when rats are deficient in salt, they don’t do activities they normally enjoy.
The recommended daily salt intake for an adult is four grams, although experts say the body needs only half as much.
However, most adults in the developed world consume（消耗）around ten grams a day, mainly because their diets contain high salt amounts. Today, 77 percent of US salt intake comes from processed and restaurant foods, like frozen dinners and fast food.
The minerals in salt are required by the body—in small quantities—to help move liquid in and out of cells. But too much can cause diseases, for example high blood pressure.
Today scientists are finding that salt is an addictive substance—almost like a drug.
One sign of addiction is using a substance even when it’s known to be harmful. Many people are told to eat less salt due to health concerns, but they have trouble doing so because they like the taste and find low-salt foods tasteless.
Humans have a long history of eating salt. In the Stone Age, people didn’t need to find salt, because they hunted most of their food, and ate a lot of red meat, which has plenty of salt in it. But when people began to farm, about 10,000 BC, they started to eat mainly grains like rice and wheat, and very little meat. Then they had to find another way to get salt.
1.What does the underlined word "deficient" in the fourth paragraph mean?
A. enough B. far from enough
C. more than enough D. plenty
2.The major role of salt is to ________.
A. help the body work well
B. help fight against depression
D. help people get rid of an addiction to drugs
D. help people enjoy sugary substances
3.Which of the following statements is true?
A. People have trouble reducing salt because they don't know it is harmful to eat too much of it.
B. Before 10,000 BC, human beings did not need salt.
C. The richer the country is, the more salt is eaten there.
D. Taking more than 4 grams of salt a day can be harmful for an adult's health.
4.What kind of food should people eat more of?
A. Frozen food B. Fast food
C. Red meat D. Low-salt food

School is still out for the summer, but at Eastern Senior High School,students are hard at work.In a garden bursting with vegetables and herbs, nearly a dozen teenagers are harvesting them for the weekend's farmers market. They work Tuesday through Saturday with City Blossoms, a non-profit that brings community gardens to schools and other places where kids gather in urban areas.
Roshawn Little, going into her junior year at Eastern, believes that working in the garden has taught her to try all sorts of new things—like eating different kinds of vegetables more often. And she has taken those healthy behaviors home with her and her family now buy more fruits and vegetables.“We mainly live around liquor（酒）stores and snack stores. There aren’t that many grocery stores. They're way out, and you have to drive so far”—a common problem in low-income urban areas.
City Blossoms is one of many groups across the country teaming up with local communities to establish school gardens, like the one at Eastern. These gardens, advocates say, are really outdoor classrooms where kids learn valuable lessons — not just about nutrition, but also about science and math, even business skills. For example, the gardens can be used for math lessons—like calculating the area of a plant bed—or learning the science of how plants grow.
On a recent weekend at the Aya farmers market, the kids work at a table decorated with handmade signs that read “onions” and “garlic”, inviting people to try their herbed salt with bread. Working at the market helps them practice public speaking skills and business skills.
Nadine Joyner of a nutrition education company has a food table next to the kids at the market and often buys produce from them. She is constantly impressed by the kids’ knowledge of what they're selling—they know how to grow it, how to prepare it, and how to cook it
1.What do students at Eastern do with the harvested vegetables?
A.Sell them on market . B.Take them to school.
C.Give them to farmers. D.Share them at home.
2.What can we infer about the area Little lives in?
A.It is inconvenient in traffic. B.It is crowded with grocery stores.
C.It has poor access to fresh foods. D.It suffers from income inequality.
3.Why does City Blossoms establish school gardens?
A.To provide nutritious food. B.To improve classroom conditions.
C.To cooperate with local community. D.To create outdoor learning chances.
4.Which may be the best title for this text?
A.Green Vegetables, Healthy Gardeners B.School Garden: a Promise Land in Summer
C.Young Gardeners, Knowledgeable Minds D.City Blossoms: an Exciting Garden Project

When my friends went to college in great delight, I restarted my senior high school life．My spirit sank．Surrounded by strange classmates, I felt like I was in a maze and was sorry about myself．There were some complex feelings in my minds．I was frightened, nervous and lonely．
To make matters worse, I recalled my failure again and again, which put more pressure on me than I could bear．As a result, I was always feeling down during class time．
My teacher found me spiritless．One day he asked me to come to his office and told me about his attitude towards life: we might suffer from mistakes, but it’s important to learn lessons from them．All the pains and the embarrassing things we experience are part of the process．So keep up your spirit! At last, he added, “If you are optimistic, things you want may happen to you!”
Warmth rushed through my soul．I suddenly found the sun shining again when I stepped out of his office．
With the teacher’s help, I eventually got over my depression．From then on, I no longer bowed my head and began smiling to my classmates．I would put up my hand confidently in class and play with my new friends in my spare time．Meanwhile, I was gradually embraced by my classmates．
Now faced with fierce competition, we all study hard because we know that every second counts．Moreover, there is an atmosphere of mutual trust and respect between us．I love my class; I love my classmates!
To be frank, I still have a thirst for my dream university, but I’m not afraid of failure because I can profit by it．With parents and teachers’ encouragement, I’m quite certain of my success and I’m sure I can fly high．

The "best years of your life"? Maybe not, but you can learn to make the most of your high school days.
1. Learn to appreciate small things. Whether it's having a computer, having friends, having a good supply of food, a bed to sleep on, family that loves you, having a decent education or simply being born in this world. Remember that the point of life is for you to enjoy it. 1. Remember that these are the last few years you will be able to enjoy yourself without having to worry about the responsibility of an adult, but make sure you prepare yourself for when you do become one. When you actually become an adult, you'll learn to love that responsibility and you probably never want to go back.
2. 2.. Unlike what many articles state, you don't have to be popular and have a gazillion friends to be happy. In fact, many of the "friends" you have when you are popular are not true friends. Try to have friends that like you who you are, not just because you are wearing a certain brand of shoes or something like that. These are people who shop at the same store as you; not someone who will sympathize with you when your dog dies.
3. Keep your grades up. 3.This also sets you up to get into a college you want to go to, which in turn prepares you for a career you will enjoy, improving your quality of life in the future. You'll get cheap car insurance as well if you have at least a B or A average.
4. 4.. Participating in clubs, activities, and sports increases your chances of meeting new friends. While you only need 4 or 5 close friends, that doesn't mean you shouldn't try to meet new people. Participating gives you something to do instead of sitting bored at home and wallowing in self-pity.
5. Work at a job you can enjoy. Working is a great way to gain experience and to meet other people. 5.This will look great on your resume. If you can't find work, especially in this hard economic time, volunteer or make your own job.
A. You should also find a hobby that is meaningful or practical.
B. Be happy, and life will reward you.
C. There is nothing more satisfying than seeing your hard work pay off in the form of A's and B's (but mainly A's).
D. Choose your friends wisely.
E. When you do get out of college, interviewing companies will look at your prior work experience.
F. Be sociable.
G. Even though you want to enjoy your teen life as best as possible, don't slack off in school.
