Reading Laboratory.

Exercise 1. Reading Laboratory.

The teacher will lead group reading, separating the sentences at reasonable points to facilitate group repetition by the students.

e.g. It is not easy - to kill a frog. - Amphibians as a group -

have existed on earth - for 350 millions years, - so the phenomenon - that’s killing them - must be something

- that has happened - fairly recently. - For now, - scientist

have no answer - but they do have - several clues.

¿Que esta matando nuestras ranas?
