- •Put questions to the following sentences:
- •Start from the second component
- •Choose as many words from the table оf ex. 1 as you can and form sensible sentences in Present Simple (affirmative, negative and interrogative).
- •Specialist Reading
- •Mark the following sentences as true (t) or false (f). Then read the text “Diodes” and check yourself.
- •Read the text again and complete the sentences with the correct ending.
- •Work in pairs. Ask your partner questions based on the text. Make sure you use correct auxiliary verb.
- •Speaking
- •In Russian write a content-based summary of the text you have translated.
- •Make a reverse written translation (from Russian into English) of your summary.
- •Find more information about conduction of current in a semiconductor diode and tell your group mates.
Mind the word-order and compile sentences from the following words:
For example:
A\tube\is\this\vacuum. – This is a vacuum tube.
Different\in\vacuum\doesn’t\diodes\current\flow\directions\in.
What\through\the\flows\tube\?
Do\diodes\know\you\that\gas\is\some\a\there\in\?
Does\element\current\flow\one\from\to\other\through\a\gas\the\?
The\you\describe\a\can\circuit\of\diode?
Cathode\a\the\heater\has?
The\heater\have\another\must\energy\source\of?
When heated the cathode emits electrons.
Diodes\are\used\where\?
Diodes\are\rectifiers\of\alternating\voltages\as\detectors\of\radio\signals\and\as\switching\devices\used.
Negative\on\the\cathode\repel\voltages\electrons\toward\the\the\plate.
Attracts\the\electrons\what\?
