5．When you think of what to eat when you're trying to build muscles，fruits may not be the first that comes to mind．But fruits are just as important as any other food．Their potassium（鉀）helps make and build muscles，the carbs（碳水化合物）spare your body from burning your muscles for fuel and the antioxidants（抗氧化物）protect the muscles from damage．
Potassium builds muscles．You need enough potassium in your diet to help build muscles．Adults need 4，700 milligrams of potassium a day．Any fruit can help you meet your daily potassium needs，but be sure to include those that are especially good sources，such as cantaloupe，bananas，oranges，kiwifruit，prunes and dried apricots．
Carbs provide your body with energy，and if you don't get enough，your body might burn your muscles for energy instead．The Academy of Nutrition and Dietetics says that Carbs are the major nutrient in fruit and make a healthy choice on your muscle-growing diet．Healthy，high-carb fruits include grapes，pears，cherries，pineapples and dates．
Antioxidants protect muscles．Large amounts of exercise causes chemical reactions that may damage cells，and this may lead you to consider adding antioxidants to your daily routine．But when it comes to antioxidants and health，it's always better to get them from food．Fruits are rich in a number of antioxidants，including vitamin C．Load up on antioxidants to protect your muscles by filling your diet with mangoes，grapefruit，apples and berries．
There are a number of ways you can-add fruit to your muscle-building diet to get all the nutritional benefits．Start by making fruit the sweet ending to your meals．Blend（摻）it up with Greek yogurt to get the nutrients your body needs for refreshment．Fruit also makes．an easy and convenient snack choice．

4．Thanks to a successful crowd-funding campaign，Dion Leonard，an extreme marathon runner is adopting a stray pup（流浪狗）he met while running a 155-mile race in the Gobi desert in China．The funds（基金）that were raised will help cover medical expenses so that the dog can be transported from China to Leonard's home of Edinburgh，Scotland．
The female dog，who Leonard appropriately named Gobi，joined Leonard on day two of the annual 4 Deserts Race Series and ran side-by-side with him for 77 miles．Leonard noticed Gobi running with 101 runners during the first day，but on the second day，Gobi was on the start line，looking up at him．"This was the first contact I had with her and as I ran off the line I noticed her by my side，"he said．"I didn't speak much to her that day，but at the finish line she followed me into the tent and we slept next to each other．That was it then．"
Leonard shared his sleeping space，water and food with his small companion during the race．He even lent her a hand when needed．"I carried her across rivers that she could not cross on her own，"he wrote on his Crowdfunder page．
After the race，it was clear to Leonard that he had developed a special bond with the pup and started researching ways to get Gobi to the UK．He learned that it would take four months for Gobi to be medically checked and cleared for entry，all of which will cost 6，560 USD，an amountthathasbeensurpassed（超過）duetoasuccessfulCrowdfunder campaignthatraised 13，330 USD．
