With all the wars, fighting and sadness in the world today, it's not only necessary, but also essential to have a good sense of humor just to help us get through each and every day of our lives. Putting a smile on someone's face when you know they are feeling down in the dumps ( 處于沮喪中), as the saying goes, makes me feel good and warms my heart.

How would you feel if you could not joke around with your wife, husband, child, co-worker neighbor, close friend, or even just someone that you are standing in line with at your comer store? I am always saying things that make others smile or laugh, even if I don't know the person I'm joking around with.My Grandma always found humor in everything she did, even if it was the hardest job anyone could imagine.This not only relieves stress in any situation, but also is common courtesy (禮貌) to speak to others that are around you.

I know of a few people that don’t have a funny bone in their bodies, as they say.Everyone around them could be rolling on the floor after hearing a great joke and they would sit there without the slightest smile on their face.They don't get the joke that makes others laugh. I am busting a gut while they just sit there, looking at me as if I were from outer space. How can people not get a really funny joke?

Laughing is essential to keep your stress levels under control. Without humor we would find ourselves with a lot of psychological problems, or on a lot of medications to keep us from going crazy. There is too much sadness in this present world. It drives people crazy. We all need to find a way to bypass the sadness and bring a little light into our lives. So, I believe our best medicine is to get together and tell some jokes and have some fun laughing together.

1.According to the author, humor is useful in the aspect that ____________.

A. it makes people more confident

B. it can pick up people' s spirits

C. it can help get rid of the cruelty in the world

D. it can help people get on well with others

2.The phrase “busting a gut" in the third paragraph can be replaced by __________.

A. explaining carefully B. speaking loud

C. keeping silent D. laughing hard

A. talk about his own understanding of humor

B. encourage people to be humorous in daily life

C. introduce a practical way to get through daily life

Early risers are most likely to be healthy, wealthy and wise, according to the old saying. But those who are early to bed and early to rise do not always have advantages, researchers say. They have found that night owls（夜貓子） are generally brighter and wealthier than those who are able to get up early in the morning.

Experts from the University of Madrid carried out tests on around 1,000 teenagers and found that those who preferred to stay up late showed the kind of intelligence to find good jobs and earn much money. Larks or “morning people”, however, often get better exam results, possibly because lessons are held at the wrong time of day for night owls.

The researchers examined the habits and body clocks of the young people to determine whether they liked to stay up late and sleep later in the morning, or preferred to go to bed early and were at their best state in the morning. School performance and problem solving ability, were judged and test grades in the major subjects were also taken into consideration.

Jim Horne, professor of psychophysiology at Loughborough University, said: “Evening types tend（傾向） to be the more creative types, the poets, artists and inventors, while the morning types are considered to be civil servants and accountants（會計）. ”

1.The researchers from the University of Madrid found _______.

A．morning people will probably find good jobs and earn a lot

B．morning people show higher intelligence from an early age

C．night owls may earn more money than morning people

D．night owls might be healthier than morning people

2.Early risers often do well in exams possibly because_______.

A．they go to bed by 10p.m. regularly

B．they make full preparations before exam

C．lessons are held at the right time for them

D．they have longer time to prepare for their lessons

3.The research may include questions about the following EXCEPT_______.

A．favorite sports

B．grades in main subjects

C．living habits and body clocks

D．school performance

4. In Jim Horne’ opinion, Larks may choose to be _______ in the future.

A．inventors B．artists

C．poets D．civil servants

While recent studies show a glass of wine or one drink a day can help protect against heart disease, more than that can cause other health problems such as liver and kidney(肝腎) disease and cancer.
