Welcome to Mr Aslanov’s cefr lessons

 
Q1. 
The avocado originated in the state of Puebla, Mexico. The native undomesticated variety is small, 
with dark black skin, and contains a large seed. The oldest evidence of avocado use was found in a cave 
located in Coxcatlon, Mexico, that dates to around 10,000 BC. The avocado tree also has a long period of 
cultivation in Central and South America. A water jar shaped like an avocado, dating to AD 900, was 
discovered in the pre Incan city of Chan Chan. 
 
Q2. 
The word ‘avocado’ comes from the Spanish ‘aguacate’. Avocados were known by the Aztecs as ‘the 
fertility fruit’. In some countries of South America, such as Argentina, Bolivia, Chile, Peru, and Uruguay, 
the avocado is known by its Quechua name ‘palta’. The fruit is sometimes called an ‘avocado pear’ or 
‘alligator pear’ due to its shape and the rough green skin. It is known as ‘Butter Fruit’ in parts of India. 
Q3. 
The avocado tree does not tolerate freezing temperatures, and can be grown only in subtropical or 
tropical climates. High winds reduce the humidity, dehydrate the flowers, and affect pollination. When 
even a mild frost occurs, premature fruit drop may occur, although the Hass cultivar can tolerate 
temperatures down to 1°C. The trees also need well aerated soils, ideally more than 1 m deep. Yield is 
reduced when the irrigation water is highly saline. These soil and climate conditions are available only in a 
few areas of the world. 
Q4. 
An average avocado tree produces about 500 avocados annually. Commercial orchards produce an 
average of seven tonnes per hectare each year, with some orchards achieving 20 tonnes per hectare. The 
avocado is a climacteric fruit, which means it matures on the tree, but ripens off the tree. Avocados that fall 
off the tree ripen on the ground. Generally, the fruit is picked once it reaches maturity. Avocados used in 
commerce are picked hard and green and kept in coolers until they reach their final destination.
