阅读下面的短文，并根据短文后的要求答题（请注意问题后的字数要求）。

[1] Many people spend a lot of time making money because they believe the money itself will make them happy, or will guard them against things that will make them unhappy．They make great efforts to achieve that perfect relationship, the perfect house, the beautiful body, the approval of others, all in an attempt to be happy.

[2] Sometimes these things make people happy; other times, people stress over not having reached the goals, or reach them and find they’re still unhappy．Other times, people focus on just one goal and don’t have time for other things that will make them truly happy.

[3] Some experts studying human happiness and the factors that contribute to it have identified several key areas of life that seem to be more related to personal happiness．Some of them are the things like money, friends, health and living conditions; others are things you may not think of in your daily life, such as your neighborhood and sense of meaning in life.

[4] So while setting your goals, remember all of the areas of life that are important to you and find a balanced lifestyle including social support, personal development, physical health and meaningful pursuits(追求) besides career success and financial security．_____________, your attitude about life and the things that happen to you each day can also have a great effect on your level of happiness and life satisfaction．In addition to being optimistic, happy people tend to believe they are the masters of their fate, rather than the victims of circumstance．

[5] Explore the state of your life, assess how truly happy you are, and find a direction to work toward that will likely bring more happiness．Reach your goals, set new ones and live a life that truly makes you happy.

Translate the underlined sentence in Paragraph 5 into Chinese.

Do dogs understand us?

Be careful what you say around your dog. It might understand more than you think.

A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).

In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.

In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.

The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.          

Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.

It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!
