The gorillas（大猩猩）in the valleys in the south often lived together in groups of several tens. They were fond of drinking wine, and even fonder of imitating man's 61 （behave）.
People knew very well their 62 （habit） and often put wine on the roadside together with many straw sandals 63 were connected together with ropes.
The gorillas knew this was 64 trick to lure(引诱)them into traps and cursed: "Humph! Do you think we don't know your tricks? We'll never be taken in!" So they called one another, 65 (turn) round and left.
But they had smelled the aroma(香味)of the wine already, and couldn't bear to part with it. Even after they left, they would turn their heads to look back. 66 they saw no one there, they would turn back; and after they turned back, they were afraid of 67 (cheat), and left again. After much hesitation, they 68 (final) said to themselves: "Just for a taste of the wine. It won't matter as long as we don't get drunk.”
Shortly afterwards, they agreed 69 (come) back to drink the wine. When they got drunk, they forgot everything. Every gorilla put on the straw sandals and imitated the way man walks.
As a result, they fell down one after another and all of them 70 (catch) alive by people.
