    Parents often say that they don't mind what their children do in life just as long as they are happy. Happiness and pleasure are almost universally seen as among the most precious human goods.1.

Philosopher Jeremy Bentham believed that all sources of pleasure are of equal quality, but John Stuart Mill disagreed. Mill argued for a difference between higher and lower pleasure.2.Lower pleasure, in contrast, requires mere (仅仅的；纯粹的) senses.

The entire debate assumes a clear divide between the physical and the mental.3.What will it mean for our ideas about pleasure?

4.Food is usually considered to be the lower pleasure. All animals eat, using the senses of smell and taste. It doesn't require any complex cognition (认知) to conclude that something is delicious. However, these people failed to appreciate something that the French food writer Jean Anthelme Brillat-Savarin captured. That is, "Animals feed; man eats; only the man of intellect(才智) knows how to eat."

Eating shows that the difference between higher pleasure and lower pleasure is not what you enjoy but how you enjoy it.5.Preparing it using the powers of reflection and attention turns it into a higher pleasure.

A. The dining table is a good place to start.

B. Wolfing down your food is a lower kind of pleasure.

C. What's the real difference between high and low pleasure?

D. What happens if the physical and the mental cannot be separated?

E. All philosophers believed that cookery could never be a form of art.

F. Higher pleasure depends on human abilities such as self-awareness or language use.

G. However, disagreements will be caused about whether some forms of pleasure are better than others.

    Whenever we see a button (按钮), we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the “on/off” button on the TV. But some buttons are actually fake, like the “close” button on a lift.

Many people are in the habit of pressing the “close” button because they don’t have the patience to wait for the lift doors to shut. But lifts’“close” buttons are a complete scam, at least in the US—the doors will not close any faster no matter how hard you press.

It started in the 1990s when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.

But to normal lift riders, the buttons aren’t completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control.

“Perceived (能够感知的) control is very important. It reduces stress and increases well-being,” Ellen J. Langer, a psychology professor, said, “Having a lack of control is associated with depression.”

Experts have revealed that a lot of buttons that don’t do anything exist in our lives for this same purpose. For example, many offices in the US have fake thermostats (温度调节器) because people tend to feel better when they think they can control the temperature in their workspace.

But psychologists found it interesting that even when people are aware of these little “white lies”, they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

“That habit is here to stay,” John Kounios, a psychology professor, said, ‘‘Even though I have real doubts about the traffic light buttons, I always press them. After all, I’ve got nothing else to do while waiting. So why not press the button in the hope that this one will work?”

A. To describe some different kinds of fake buttons.

B. To analyze(分析) the functions (作用) of fake buttons.

C. To explore people’ different habits when it comes to pushing buttons.

D. To explain the advantages and disadvantages of fake buttons.

2.What does the underlined word “scam” mean?

A. Trick. B. Tool.

C. Button. D. Joke.

3.According to John Kounios, people who press fake buttons ______.

A. don’t know that what they press is fake B. should give up this habit

C. consider what they do to be meaningless D. probably do so to kill time

    In today's society, almost half of all marriages in America end in divorce, which means many children have divorced parents, and 1 am by no means a rare case.There are plenty of other people understanding the difficulty of having separated parents and living in two households. Despite this, people who haven't personally experienced divorce really have no idea what it's like.

My parents have handled divorce and joint custody(监护) well, at least better than expected. Occasionally my parents put up the curtain to block my brother and I from the reality and I will get a glimpse of the not-so-bright-and-sunny reality, the fact that my parents simply don't like each other, let along get along. They try to make sure my brother and I don't overhear the argument and do their best to keep my brother and I out of their issues.

Last Mother's Day I woke up at my dad's house with a text message from my mom saying, "Call me when u can."I rolled out of bed and dialed her number. On the other end of the phone I could hear my mom's trembling voice. "Your dad isn't letting me have you until 7 tonight. " I knew Mother's Day was important to her and me. I began to get angry with my dad, but I told myself that getting mad and fueling my mom's anger towards my dad wouldn't help. Later my father told me that he had planned to spend time with my grandma and step-mom for Mother's Day, which I understood and accepted but I also understood why my mom wouldn't accept it.

While having divorced parents is difficult, I have learned a lot about how to deal with conflict from an early age and I've been blessed with an extremely large family, which is an amazing network of support.
