     Pre-reading task

T.: Today we are going to learn about bees and various types of bees.

     T.: In order to understand the topic better, it is important to learn new words. Look at your lexical cards. (card#1)

• System: pattern, method
• Hive: bee home
• Starve: to become ill or even die because of a lack of food
• Larvae: baby insects
• Nutrients: compounds in food that help you grow and stay healthy

Reading

T.: Let's read the text “Kinds of Bees”

“Kinds of Bees” 

Bees are flying insects closely related to wasps and ants, and are known for their role in pollination and for producing honey and beeswax. Bees are a monophyletic lineage within the superfamily Apoidea, presently considered as a clade Anthophila. There are nearly 20,000 known species of bees in seven to nine recognized families,[1] though many are undescribed and the actual number is probably higher. They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants.

Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae.

Bees have a long proboscis (a complex "tongue") that enables them to obtain the nectar from flowers. They have antennae almost universally made up of 13 segments in males and 12 in females, as is typical for the superfamily. Bees all have two pairs of wings, the hind pair being the smaller of the two; in a very few species, one sex or caste has relatively short wings that make flight difficult or impossible, but none are wingless.

Tiny stingless bee species exist whose workers are less than 2 mm (0.079 in) long.[2] The largest bee in the world is Megachile pluto, a leafcutter bee whose females can attain a length of 39 mm (1.5"). Members of the family Halictidae, or sweat bees, are the most common type of bee in the Northern Hemisphere, though they are small and often mistaken for wasps or flies.

The best-known bee species is the European honey bee, which, as its name suggests, produces honey, as do a few other types of bee. Human management of this species is known as beekeeping or apiculture.

Bees are the favorite meal of Merops apiaster, the bee-eater bird. Other common predators are kingbirds, mockingbirds, beewolves, and dragonflies.

While-reading task

     T.: Let’s divide into four groups, while reading the text, make up questions to the text using new items.
