If you’re training for a marathon , a proper plan for water intake (摄入) is important. Of course, there’s the risk of dehydration (脱水). But athletes now know they can also get into trouble by drinking too much. Too much water intake can lower levels of sodium (钠) in the blood . The death of a 28-year-old woman following the Boston Marathon caught the attention of many runners and led to new research.
Experts advise long distance runners to replace the liquids they sweat out. Their goal is to try to keep someone from not getting dehydrated by more than 2 percent of their body weight.
One technique for deciding how much water you need is to get the exact numbers. Runners have to weight themselves before and after a run to determine how much water they’ve lost. If their weight drops by more than 2 percent, they have not drunk enough water.
Hyponatremia occurs when runners drink so much water that blood salt levels drop off. A study published last year tested 488 runners who completed the Boston Marathon and found 13 percent of them had dangerously low blood salt levels. The first sign that runners may notice is slightly swelling in the hands. They can’t get their rings off, and then they might feel sick. They may not remember where they are. In fact, most runners get enough salt to get back to normal levels by eating just one meal after a run. Contrary to the old advice that runners should drink as much as they can to prevent dehydration , the new research has shown that the body is a remarkable machine that actually tells you via thirst when you need water .

Sweetest Day in America is always the third Saturday in October. This holiday is much more important in some regions than in others (Detroit, Cleveland and Buffalo being the biggest Sweetest Day cities). It is a holiday that is gaining in popularity every year throughout the country.
Sweetest Day is celebrated on the third Saturday in October as a day to make someone happy. It is an occasion which offers all of us an opportunity to remember not only the sick, aged, and orphaned, but also friends, relatives and associates whose helpfulness and kindness we have enjoyed.
Over 60 years ago, a man in Cleveland, believing that the city’s orphans and shut-ins (卧病在床的人) too often felt forgotten and neglected, thought of the idea of showing them that they were remembered. He did this through the distribution of small gifts. With the help of his friends and neighbors, he distributed these small remembrances on a Saturday in October. During the years that followed, other Clevelanders began to participate in the celebration ceremony, which came to be called “Sweetest Day”. In time, the Sweetest Day idea of spreading cheer to the underprivileged was broadened to include everyone, and became an occasion for remembering others with a kind act or a small remembrance. And soon the idea spread to other cities all over the country.
Sweetest Day is not based on any single group’s religious affection or on a family relationship. It is a reminder that a thoughtful word or deed enriches life and gives it meaning.
Because for many people remembering takes the form of gift-giving, Sweetest Day offers us the opportunity to show others that we care, in a practical way.We can learn from the first paragraph that Sweetest Day is ________.
A. sometimes the third Saturday in October
B. hardly celebrated in Detroit
C. of equal importance in every part of the USA.
D. getting increasingly popular in the USASweetest Day was originally intended to remember ________.
| A．the young and disabled | B．friends and relatives |
| C．orphans and shut-ins | D．the sick and aged |

| A．Detroit | B．Cleveland |
| C．Buffalo | D．Washington |
Now on Sweetest Day gifts are given to those ________.
| A．we care | B．we admire |
| C．in need of help | D．in trouble |
Almost every person has a sweet tooth. Even if you love sugar really much it is now time to learn a very important but also very little known truth regarding sugar. Sugar really has no benefits for your health and the only actual benefits from it are that it sweetens your taste buds and satisfies your sweet tooth. Sugar is not a natural substance and is produced through a special industrial process called refining(炼制) the sugar cane. Sugar cane has a lot of health benefits but in the refining process it loses all its vitamins, proteins, minerals and other nutrients which are essential. Therefore, you end up consuming empty calories only. Moreover, your body gets all the sugar it needs from the consumption of regular food such as bread, vegetables, fruits and so on. No added sugar is really needed. However, most people love sugar and simply feel like they need to eat food high in sugar.
The latest researches show that the recommended intake of sugar which is healthy for your body on daily bases for children, men and women is as follows:
·children-- 12 grams, which equals 3 teaspoons;
·men-- 36 grams, which equals 9 teaspoons;
·women-- 20 grams, which equals 5 teaspoons.
The sugar intake when it comes to diabetics(糖尿病人)is a lot different based on the type of diabetes. It is best to consult your doctor in order to find out about your personal requirements for the intake of sugar before you follow the guidelines mentioned earlier.
When we speak about the recommended daily intake of sugar, it does not mean only simple sugars that we consume in the form of desserts and sodas but also sugars that come from complex carbohydrates and also fruit. You should not exclude all of the sugar from your diet but you should make up for all the extra sugar you eat by exercising. It is not really simple to calculate your sugar intake but you can still control it if you try and you can also get a bigger amount of exercise in order to regulate the sugar amount that is being taken in and then digested by your body.The passage mainly talks about__________
| A．the benefits and harm of taking in sugar |
| B．the process of refining the sugar cane |
| C．the causes of different types of diabetes |
| D．the proper intake of sugar for different people |
The underlined phrase “has a sweet tooth” means__________.
| A．has tooth problems | B．prefers sweet food |
| C．has a sweet mouth | D．is always lying |
Which of the following statements is true?
| A．Sugar cane has no benefits to physical health. |
| B．We also take in sugar from fruit and food |
| C．The recommended intake of sugar applies to all. |
| D．Many people know about the proper intake of sugar. |
As for diabetics, __________.
| A．they can never take in any sugar in their diet |
| B．they can take in no more than 20 gram of sugar every day |
| C．they needn’t ask their doctors for advice about their diet |
| D．the sugar intake varies depending on the type of diabetes |
Taking a picture of your tongue with a mobile phone could soon instantly tell you how healthy you are.
Researchers believe the images could reveal important information about a patient’s health—and even give them early warning of serious illness. A team at the University of Missouri is developing a system that can analyze pictures using a 5,000-year-old Chinese principle. It is based on the flow and balance of positive and negative energies in the body, and uses the tongue as a key to the physical health, or “zheng”, of a person. “Within a year, our ultimate goal is to create an application for smartphones that will allow anyone to take a photo of their tongue and learn the status of their zheng.”
The software analyses images based on the tongue’s color and coating to distinguish between tongues showing signs of ‘hot’ or ‘cold’ zheng. Shades of red and yellow are associated with hot zheng, whereas a white coating on the tongue is a sign of cold zheng. “Hot and cold zheng doesn’t refer directly to body temperature,” said Xu, “Rather, it refers to a series of symptoms associated with the state of the body as a whole.”
For the study, 263 gastritis(胃炎) patients and 48 healthy volunteers had their tongues analyzed. The gastritis patients were classified by whether they showed infection by a certain bacteria, known as Helicobacter pylori(幽门螺旋杆菌), as well as the intensity of their gastritis symptoms. In addition, most of the gastritis patients had been previously classified with either hot or cold zheng.
This allowed the researchers to prove the accuracy of the software’s analysis.
“Our software was able to classify people based on their zheng status,” said study co-author Ye Duan, associate professor of computer science at MU.
“As we continue to work on the software we hope to improve its ability,” Duan said. “Eventually everyone will be able to use this tool at home using webcams or smartphone applications”.
“That will allow them to monitor their zheng and get an early warning about possible ailments.”According to Chinese medicine, zheng refers to__________.
| A．the color and coating of one’s tongue |
| B．one’s body temperature |
| C．the physical health of a person |
| D．the possible illness of a person |
The study led by Dong Xu proves__________.
| A．the greatness of Chinese medicine |
| B．the effects of the software |
| C．the software’s great prospect |
| D．the advancement of smart phones |
The underlined word “ailments” can be replaced by__________.
| A．analysis | B．illnesses |
| C．effects | D．applications |
It can be inferred from the passage that__________.
| A．the software still needs improvement |
| B．the software has been in market for a year |
| C．the subjects in the study are all gastritis patients |
| D．the subjects in the study are classified by age |
English is fast becoming the only language of a new generation of educated Arabs.
This isn't a good thing for the region or the rest of the world. The journalism school at the AUD(迪拜美国大学)is the only modern program in the Middle East that allows students to study in Arabic. Still, many students arrive with poorly written Arabic and the formal spoken language and require refresher Arabic language courses.
Literacy(识字能力) in the Gulf States is 98%, according to UNESCO. But that literacy is increasingly in English, not Arabic.
This English bias(偏爱) starts early, with children in private "model" schools in the United Arab Emirates studying all their subjects, including math and science, in English. But the trend appears to be taking hold regionwide. In Saudi Arabia, many upper-middle-class families speak English at home -- not just at work .
One Arabic official told me his own children do not speak Arabic fluently. He said he put them in English schools to help ensure they'd have great career prospects. But now he says he regrets that his children don't feel comfortable speaking the language of their forefathers.
Why is there the anxiety among these elites? I am continually told that what I've experienced anecdotally is true: The wealthier the family, the less likely its members speak Arabic at home. If people in the same country don't speak the same language, how can they work across class lines to solve the problems of high unemployment that affect even oil-rich Saudi Arabia?
For executives(行政主管) trying to build local businesses, the English bias is a challenge. The dean of the AUD's school of journalism, Ali Al Jaber, told me, "If you can't address your own people, then you can't be successful."
Sure, English is the world's business language. More Chinese are learning English right now than there are Americans in the U.S. But China has struck a bilingual balance. Its research universities teach some of the world's brightest minds in Chinese. Professor Wardeh finds much for Arab nations to admire in this model.The passage mainly tells us_____________.
| A．English is the world’s business language |
| B．the English bias in Saudi Arabia |
| C．the school education in Saudi Arabia |
| D．the bilingual balance in China |
Many Arabic parents prefer their children to speak English because__________.
| A．they think it’s a symbol of class |
| B．English is the world’s business language |
| C．they consider Arabic hard to learn |
| D．they believe it’s an advantage in their future careers |
The underlined phrase “this model” refers to__________
| A．the education system in China |
| B．the popularity of English in Saudi Arabia |
| C．to popularize English in upper-class families |
| D．to improve literacy in Arabic countries |
We can know from the passage that__________.
| A．the popularity of English in Saudi Arabia is a good thing |
| B．there is no problem of unemployment in Saudi Arabia |
| C．the poor in Saudi Arabia are more likely to speak Arabic |
| D．the English bias doesn’t affect the local business |
If I had known the following things when I was in high school, my life would have been 100% easier back then and probably would have helped me greatly. I realized some of these things I was told but being young and ignorant I refused to listen.
1.Your high school sweetheart will probably not be your spouse.
When I was in school, I thought my boyfriend and I were the “one and only true love”. Honestly as most young people do, statistically only like 2% of people end up marrying their high school sweethearts and even if they do they probably won’t be as happy as they were in high school. Being an adult is very stressful and your relationships become different.
2. __________________________________________________
How many kids play sports per year? How many kids are good enough to get a scholarship by playing sports? How many of them even make it to the Olympics after college or university? The kids who actually stay at home and focus on getting good at computers or math are the ones who make the most in the adult world financially.
3. It doesn’t matter what university you go to.
I was convinced I was going to go to a great art school when I graduated and I was so stressed out about it that I ended up dropping out of school. In reality my life wasn’t over; I only got my GED a year ago but I am in a decent school now. In the real world when you go to apply somewhere all they care about is “do you have a degree or a certification”?
4. Your friends probably won’t be your friends after you graduate.
I really thought I was going to get an apartment with my friends and our kids were going to grow up together. The truth is, when people grow up they move, have kids, get married, and therefore change. You will change; you will not be the same person you were. High school is just a transitional period of your life. So don’t worry about who is saying what about you or who is making fun of whom. What is the purpose of the passage?
| A．To recall the experiences in high school. |
| B．To warn high school students about love in high school. |
| C．To give advice to high school students. |
| D．To encourage high school students to focus on study. |
The writer once dropped out of a college because __________.
| A．she decided to marry her sweetheart |
| B．she was bearing too much pressure |
| C．her family was going through financial problems |
| D．she was offered a good job before graduation |
Why do many sweethearts in high school get separated later?
| A．They aren’t able to go to the same university. |
| B．Their parents won’t approve of their relationships. |
| C．They will meet much better persons after growing up. |
| D．There will be more pressure and their feelings may change. |
Which of the following subtitles can fill in the underlined blank?
| A．Your teachers are not always right. |
| B．You can’t make lifelong friends in high school. |
| C．The unpopular kids are the ones who make the most money. |
| D．Education in life actually starts after graduation. |
Which of the following statements is FALSE?
| A．The writer had never heard about the advice above in high school. |
| B．In real world employers don’t care so much about which school you graduated from. |
| C．Relationships in high school won't have great effect on your later life. |
| D．It’s not easy to earn scholarships by playing sports for high school students. |
