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 .

One evening last summer, when I asked my 14-year-old son, Ray, for help with dinner, his response shocked me. "What’s a colander(漏勺)? " he asked.
I could only blame myself. In the family, nobody else’s hands went in the sauce except my own. But that night, as I explained with a touch of panic that a colander is the thing with holes in it, I wondered what else I hadn’t prepared Ray for.
As parents, while we focus on our sons’ confidence and character, we perhaps don’t always consider that we are also raising someone’s future roommates, boyfriends, husbands, or fathers. I wanted to know that I’d raised a boy who would never ask the woman in his life, "What’s for dinner?" So I came up with a plan: I would offer Ray a private home economics course. I was delighted to find that he didn’t say no. For two hours, three days a week, Ray was all mine. One day, as his tomato sauce reduced on the stove, he washed and seasoned a chicken for roasting. Then he rolled out the piecrust (馅饼皮) and filled it with apples, all while listening to my explanation on the importance of preheating an oven.
I knew that he would rather have been shooting hoops in the driveway than learning to mend socks with his mother—he tried to beg off sewing lessons, even though I insisted that one day, someone would find the sight of him fixing his own shirt very attractive— but it couldn’t be denied that he was learning, and more than just housekeeping. "I appreciate what you do as a mom," he told me one day. Ray now understands the finer points of cooking, and more importantly, he realizes there’s nothing masculine (男子气概的) about being helpless.
Now, not only can he make his own dinner, but also he can make a big meal for his family. That’s what I call a man. I’m glad that I prepared so great a present for my future daughter-in-law.Why was the author shocked at her son’s response?
| A．Because he was not well behaved. |
| B．Because he refused to help with dinner. |
| C．Because he didn’t know the common kitchen tools. |
| D．Because he was very curious about kitchen tools. |

There are many fun, free activities that you can do as a family. All that is required is a bit of imagination and some time set aside for fun. And the best part is that these are the kind of memories a child will remember for a lifetime.
Family game night
Find out any of the games that are already around the house. Kids often get computer games for Christmas or birthdays, and would love to have a chance to play with their family. Or, make up some games of your own. “Charades” is a fun game to play that will challenge a child to use his/her imagination. Divide the family into teams and let each team come up with words that the other has to act out.
________________________
Pick some time for the family to sit down and come up with their own masterpiece. It doesn't need to be just a drawing -- take some old magazines sitting around the house, let the kids cut out pictures and paste them into their own montage. Or, use items from nature. Let them use leaves, pine cones（松果）, twigs and whatever else they can find to create something from their imaginations.
Family Picnic
Taking the family for a picnic is a great way for some fun that doesn't cost any money. If the weather is nice, take them to a park or playground and let the kids have a day of playing. Or, if it is the middle of winter and a foot of snow is on the ground, set up a picnic in the living room.
Family Field Trip
A family field trip doesn't have to cost a dime. Ask a nearby farm if it would be alright to bring your kids out for a tour and to see some of the animals. Or take them to a park and make a scavenger hunt(寻物游戏) where they need to find certain items from nature. Ask a local business if you could bring the family for a tour to see how things work -- you might be surprised at the number of people who would be thrilled to share what they do with others, and it could be an interesting lesson for the kids.We can learn from the passage that “charades” ________.

Can dogs and cats live in perfect harmony in the same home? People who are thinking about adopting a dog as a friend for their cats are worried that they will fight. A recent research has found a new recipe of success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along well. Two-thirds of the homes interviewed reported a positive relationship between their cat and dog.
However, it wasn’t all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals were just opposite. For example, when a cat turns its head away it signals aggression, while a dog doing the same signals means giving up.
In homes with cats and dogs living peacefully, researchers observed a surprising behaviour. They are learning how to talk each other’s language. It is a surprise that cats can learn how to talk “dog”, and dogs can learn how to talk “cat”.
What’s interesting is that both cats and dogs have appeared to develop their intelligence. They can learn to read each other’s body signals, suggesting that the two may have more in common than was preciously suspected. Once familiar with each other’s presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together in the sofa. They can easily share the same water bowl and in some cases groom(梳理) each other.
The significance of this research on cats and dogs maygo beyond pets----to people who don’t get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.Some cats and dogs may fight when_________.
| A．they are cold to each other |

My grandfather lived only half a mile away from where I grew up in New York. Every day, he would walk down to our house and bring my dad newspapers. Along with the papers he would bring a small bag of treats (美食) for my two brothers and me.
Western New York had terrible winter weather: rain, sleet (雨夹雪), or even 3 feet of snow. Even when he was 81, he still walked the half mile every single day. As a child, I looked forward to the daily treats, but now I’m older and I realize he braved the rough weather each day just to see us smile; I now value that more than anything else.
My grandfather touched many lives. A woman who had been in hospital for five years told me her story. She said my grandfather would visit her twice a week at her home: to read to her, play bridge, or just chat. It lasted for years without stop. She had few visitors. Even a hitch-hiker who had traveled by getting free rides from passing cars told me of my grandfather’s influence on his life. My grandfather had picked him up for free and took the traveler to his home. After learning that the man was homeless, my grandfather gave him a place to stay. The man told me that no one had ever been so nice to him. He later found a job in a supermarket.
I was touched, but not surprised to know all of the touching stories from which I understood my grandfather’s selflessness. I have since tried to learn from him to help others.
