Listening-Centered Activities

Listening I

Exercise 1

Directions: Listen to the passage and answer the following questions.

Although twins have always been a source of curiosity they are not so uncommon statistically, since they occur once in every 86 births. About one third of all twins are identical, or single-egg twin Identical twins have the same genes and, hence the same sex, hair, eyes, blood type, and bone and tooth structure Some identical twins are mirror images of each other For example, one may be left-handed, the other right-handed. some identical twins may develop their own private language Identical twins have an especially keen intuition and they often seem to think and dress alike even when away from each other In fact, even when they are separated at birth and raised apart, They may pursue the same careers, have the same interests, or die within days of each other. fraternal twins inherit a separate set of genes and are not necessarily of the same sex.

Question.

1) What is the statistical probability of twins being born?

2) How many different kinds of twins does the speaker mention? What are they?

3) What are the major differences between the two kinds of twins?
