[00:19.40]Exercise 1

[00:24.16]Directions:

[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 2 statistically 3, 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 5 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 4 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 6

[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,

[04:38.42]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 7 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.
