根据短文内容，从下框A-F选项中选出能概括每段主题的最佳选项。选项中有一项为多余项。
A. A sense of humour is not an inborn ability.
B. A sense of humour can be developed in our life.
C. A sense of humour helps us from several aspects.
D. A sense of humour means more than telling jokes.
E. A sense of humour can be expressed in many ways.
F. A sense of humour helps people to better enjoy life.
1._____
      As awareness of the benefits of humour increases, most of us want to get all the laughs we can. It seems
that almost every day there is another new discovery about the power of humour to help us physically, mentally,
emotionally, and spiritually. Every system of the body responds to laughter in some important or positive way.
2._____
     Many people mistakenly believe that we are born with a sense of humour. They think that when it comes to
a sense of humour. "either you have got it or you don't." This is false! What is true, however, is that the ability
to laugh and smile is actually something we are born with. For example, we laugh when we are tickled under the
arm, even without thinking about how to react.
3._____
     The parts of the brain and central nervous system that control laughing and smiling are mature at birth in
human infants, but that is not the same thing as having a sense of humour. (After all, when a baby laughs in his
small bed we don't rush over and say, "That kid has a great sense of humour!") Your sense of humour is
something you can develop over a lifetime. Don't be nervous before others and try to laugh at yourself-then you
will make them laugh too. 
4._____
     Humour includes a lot more than laughing and joke telling. Many people worry needlessly that they do not
have a good sense of humour because they are not good joke tellers. More than jokes, a sense of humour
requires being willing and able to see the funny side of life's situations as they happen. In fact, one of the best
definitions (定义) of a sense of humour is "the ability to see the nonserious element in a situation."
5._____
     There may be a thousand different ways to express your sense of humour, but joke telling is only one of
those ways. As more is discovered about how humour benefits our life, more people will be able to see and
enjoy the humour when they are in a difficult situation. Life depends on air, food and water, but it is made easier
to live with a good sense of humour.

The idea of test-tube babies may make you either delighted at the wonders of modern medicine or irritated while considering the moral, or legal, or technological implications of starting life in a laboratory. But if you’ve ever been pregnant yourself, one thing is certain: You wonder what it’s like to carry a test-tube baby. Are these pregnancies normal Are the babies normal

The earliest answers come from Australia, where a group of medical experts at the Queen Victoria Medical Center in Melbourne have taken a look at the continent’s first nine successful "in vitro" pregnancies. The Australians report that the pregnancies themselves seemed to proceed according to plan, but at birth some unusual trends did show up. Seven of the nine babies turned out to be girls. Six of the nine were delivered by Caesarean section (剖腹产手术). And one baby, a twin, was born with a serious heart defect and a few days later developed life-threatening problems.

What does it all mean Even the doctors don’t know for sure, because the numbers are so small. The proportion of girls to boys is high, but until there are many more test-tube babies no one will know whether that’s something that just happened to be like that or something special that happens when egg meets sperm in a test tube instead of a Fallopian tube (输卵管). The same thing is true of the single heart defect; it usually shows up in only 15 out of 60,000 births in that part of Australia, but the fact that it occurred in one out of nine test-tube babies does not necessarily mean that they are at special risk. One thing the doctors can explain is the high number of Caesareans. Most of the mothers were older, had long histories of fertility problems and in some cases had had surgery on the Fallopian tubes, all of which made them likely candidates for Caesareans anyway.

The Australian researchers report that they are quite encouraged. All the babies are now making normal progress, even the twin with the birth defects.

Which of the following explanations regarding the high number of Caesarean operations is NOT true().

A. Some mothers have passed the best age for a natural delivery.

B. Some mothers have physical problems with pregnancy.

C. Some mothers volunteer to be the candidates of the Caesarean operations.

D. Some mothers have had surgical operations on the Fallopian tubes.
