[00:27.58]Listen to the passage and answer the following questions.
[00:33.80]Although twins have always been a source of curiosity
[00:39.60]they are not so uncommon statistically, since they occur once in every 86 births.
[00:47.30]About one third of all twins are identical, or single-egg twin
[00:54.50]Identical twins have the same genes and, hence
[01:00.48]the same sex, hair, eyes, blood type, and bone and tooth structure
[01:08.76]Some identical twins are mirror images of each other
[01:14.41]For example, one may be left-handed, the other right-handed.
[01:21.40]some identical twins may develop their own private language
[01:27.44]Identical twins have an especially keen intuition
[01:33.31]and they often seem to think and dress alike even when away from each other
[01:41.16]In fact, even when they are separated at birth and raised apart,
[01:47.93]They may pursue the same careers, have the same interests,
[01:53.44]or die within days of each other.
[01:58.48]fraternal twins inherit a separate set of genes
[02:03.23]and are not necessarily of the same sex.
[02:08.66]Question.
[02:12.16]1) What is the statistical probability of twins being born?
[02:20.33]2) How many different kinds of twins does the speaker mention? What are they?
[02:29.29]3) What are the major differences between the two kinds of twins?

[03:20.16]When Robert Jones, 19, went to college this fall,
[03:26.24]They told him he looked just like a former student, Edward Gallant
[03:33.05]and a friend of Gallant's discovered they had the same birth date
[03:40.54]Both Robert and Edward were adopte
[03:45.76]When they talked with each other,
[03:49.50]they discovered that they were identical twins separated shortly after birth
[03:57.71]In fact, they were wrong: they were triplets
[04:03.68]After newspapers published their pictures,
[04:08.51]Edward's mother got a call from David Kellman
[04:14.12]"You're not going to believe this," he said, "but I believe I'm the third."

[04:29.32]Robert,Edward and David had been born to the same mother on July 12th,1976
[04:38.42]They were adopted by three different couples,
[04:43.50]none of whom was told their new son had brothers
[04:49.55]The reunion of the three boys after 19 years
[04:54.84]was a big surprise for everyone in all the families.
[05:00.53]Relatives say their resemblance extends well beyond their look
[05:07.76]All three are extroverts who have similar gestures
[05:13.85]They talk in the same way, they have the same laugh
[05:19.36]they hold their cigarettes in the same way,
[05:24.14]and all three smoke the same brand of cigarettes
[05:29.65]1)Robert jones and Edward Gallant thought they were actually twin brothers.
[05:38.11]2) David Kellman was one of the triplets.
[05:44.09]3) David learnt about his brothers on TV.
