It has been more than 50 years since Harvard Business School started admitting women, yet the institution(机构) is still trying hard to find out how to best attract and support them. Its latest effort: a program targeting women's colleges—place that are not traditional feeding grounds for the male-majority business school.

The program is called Peek. It offers juniors, seniors and recent graduates from women's colleges the opportunity to read and discuss four HBS case studies in class specially taught by top HBS members. About 50 to 70 promising students will pay $500 for their stay there.

Women make up 41 percent of Harvard Business School class of 2016—the most the school has had. In 1985, women made up only one-quarter of the graduating class. Harvard is not alone when it comes to struggling with a gender gap (性别差别). At Wharton, the class of 2016 is 40 percent women; at Standford Business School, it's 42 percent. No top business school had gotten to 50 percent yet.

    Despite the Peek program's good intention, the $500 fee bothered someone, said John A. Byrne, the editor of business school new site. "The fact that HBS would charge women for the chance of coming to campus rubbed a lot of people the wrong way,” said Byrne. HBS said the $500 fee was a “fair price” for room and daily meals at the business school for a weekend, and didn't actually cover the full costs of the program.

    For years, women students at Harvard Business School failed to keep pace with men. In 2010, Harvard business School got a new manager, Nitin Nohrin, who promised a turnaround. Nohrin designed a program to encourage women students and professors. He promised to change the school's case studies so that at least 20 percent of the people in the business texts would be women.

    Recently, South Korean star PSY's “Gangnam style” video has been popular on the Internet. It has become most people's favorite music.

In fact, the song has set the Guinness World Record for the most popular video in the history of the Internet. More than two million people have said “like” since the song was on the Internet on July 15.

    PSY's special dance moves and funny horse riding style have attracted many people. Although many people do not understand the language, the video has become the talk of the Internet. The song has come to first place in the music charts in 31 countries, including the United States, the United Kingdom, and Canada.

    “I just sang for my South Korean fans. I have never expected it to be popular in other countries,” PSY told the reporters on a concert. The song was so popular that a few of South Korean's politicians showed PSY's moves to attract supporters.

    “The song came out in mid-July. It sings about the rich life of South Korea--especially Gangnam in Seoul, where a lot of rich people live.

    Millions of people have watched the video. Many stars, such as Katy Perry, Robbie Williams and Nelly Furtado said that they love the song. These stars performed part of the song at a recent concert.

    Riding high on the success of “Gangnam Style”, PSY was signed by Scooter Braun to Braun's Schoolboy Records, a label distributed by Universal Republic.

    PSY has written many hit songs of varying styles for different singers. Prior to “Gangnam Style” his most famous composition perhaps was Lee Seung Gi's debut(首次亮相) song “Because You Are My Woman”.

    Can you imagine walking into a gym and seeing dogs lifting weights or cats jogging? We're being a bit silly thinking of dogs and cats going to the gym, but we do have a reason. Just like human beings, pets that don't get enough exercise can become overweight.   
   Overweight pets can develop serious health problems just like we can. So, if you have a pet, part of being a good owner is making sure that your pet gets the right amount and kind of exercise.

    Before you start your pet on an exercise program, be sure to schedule a check-up for your pet and ask your veterinarian how much and what type of exercise your pet needs.

    Just like humans, pets need to be started out slowly. Over time, they will get fit and be able to exercise for longer periods of time. If you exercise alongside your pet, you'll benefit, too!

    Starting out, you might want to play with your pet for 15－20 minutes at a time. Gradually, you can turn those plays into several 30－minute walks or jogs each week. If your pet is especially active, you can extend them to an hour or longer.

    Of course, some pets, such as cats, may not be easy to take for a walk or a run. These pets still need exercise, though. Don't underestimate the value of energetic indoor play, such as games of chase, for these types of pets.

    As you start exercising with your pet, here are some things to keep in mind:

    Make sure your pet has plenty of water before, during, and after exercising.

    If you have older pets, don't push them as hard.

    Watch the heat! If you are outside, exercising with your pet will be best early in the morning or later in the day.

    The third week of SEAL training means Hell Week. It is on Wednesday of Hell Week that you paddle down to the mud flats（泥滩） and spend the next 15 hours trying to survive the freezing-cold mud, the howling wind and the increasing pressure from the instructors to quit. As the sun began to set that Wednesday evening, my training class, having broken the rules, was ordered into the mud. The mud consumed each man till there was nothing visible but our heads. The instructors told us we could leave the mud if only five men would quit—just five men and we could get out of the extreme cold.

    Looking around the mud flat, it was apparent that some students were about to give up. It was still over eight hours till the sun came up--eight more hours of freezing cold. The chattering teeth and shivering moans (呻吟）of the trainees were so loud that it was hard to hear anything. And then, one voice began to echo (回荡）through the night--one voice raised in song. The song was terribly out of tune, but sung with great enthusiasm. One voice became two, and two became three, and before long everyone in the class was singing. We knew that if one man could rise above the great suffering then others could as well. The instructors threatened us with more time in the mud if we kept up the singing—but the singing went on. And somehow, the mud seemed a little warmer, the wind a little less bitter and the dawn not so far away.

    If I have learned anything in my time traveling the world it is the power of hope. The power of one person, Washington, Lincoln, King, Mandela and even a young girl from Pakistan, Malala, can change the world by giving people hope.

    So, if you want to change the world, start singing when you're up to your neck in mud.

    Before you make friends, you have to decide who you want to be your friends.

    Most people like to have friends who like to do the same kind of things they do.

    The quickest way to make a friend is to smile. When you smile, people think you are friendly and easy to talk to. It may not be easy at first to smile, but remember most people will stay away from a scaled or angry looking.

    One easy way to start a conversation with someone is to say something nice about him. Think about how great you feel when someone says something nice to you. Doesn't it make you want to keep talking to that person?

    Ask your new friends questions about themselves. Who's their favourite singer, where do they live, what do they do after school are all good questions to start a conversation. Make sure you have something to add to the conversation, too. Then someone asks you a question, do have an answer for it. There is nothing that will stop a conversation quicker than a shrug for an answer.

    Kids who show an interest in other kids and who are kind and friendly make good friends. Remember, everyone wants to be around people who like to do similar things and people who are nice to them.

With all the dietary information online, it can be hard to know what tips to follow. Watch out for these words and expressions.

Fat Is Good

It doesn't matter if you are part of the fat is GOOD for you or BAD for you group, the important question to ask is the source of the fat. If it comes from a land-based animal, and is likely to be solid at room temperature, then it is saturated （饱和的） fat whereas if it comes from fish or plants, and it is likely to be liquid at room temperature, then it is unsaturated fat. All the evidence indicates that eating more unsaturated fat than saturated fat lowers your risk of dying early.

Natural Sugar Is Better

The vast majority of sugar we consume is sucrose （蔗糖）. It is the white powdered stuff we cook with and is made up of glucose and fructose. How about sugar from honey? It is often marketed as natural and better for you. Actually, it just has its own distinct flavour, but is as sweet because of glucose and fructose.

High-pH Water

Some people think we need to eat alkali （碱） food to maintain our blood at a pH of 7.4. But everything we eat or drink passes through the stomach, which, at a pH of 1.5, is the most acidic part of the body. It is then neutralised to a pH of 7. So, nothing we eat will change the pH of our blood.

Don't Eat Anything That You Can't Pronounce

Whether foods are natural or highly processed, they are all full of chemicals. Are you supposed to fear "phenylthiocarbamide", because you can't pronounce it? This is simply the chemical responsible for the bitter taste found in brassicas, the plants in the cabbage and mustard family.

Don't Eat Food With More Than Five Ingredients（佐料）

Simple foods are not necessarily healthier for you. If I, for instance, use Chinese five spice powder in a recipe, that would count as one of the five ingredients. However, what if I added the typical components of five spice powder separately into a dish? Does that mean my recipe suddenly becomes bad because it has more than five ingredients?
