Speaking Task 1. Choose the question from the card on the topic Entertainment and fedia^ prime prime and be ready to answer it after the teacher starts the conversation. Produce a speech by giving extended answers to the questions. Share your ideas with the class. Teacher organizes a Socratic seminar, which helps him/her to assess learners while they are speaking on the toplic Entertainment and Media and he/she prepares and cuts down questions and expressions beforehand. Learners sit in a circle and answer the question using in their speech some formal and Informal expressions to present logically connected information to their classmates. Expressions: Stating an opinion The way I see it... Sorry to interrupt, but... Is it okay if I jump in for a second? Can I add something here? Can I throw my two cents in? Not necessarily Interrupting If I might add something..... I beg to differ No, I'm not so sure about that That's for sure Expressing disagreement I'd say the exact opposite I have to side with somebody (name)on this one I was just going to say that In my opinion Expressing agreement If you ask me.. That's exactly how I feel As far as I'm concerned. If you want my honest opinion..... You have a point there That's not always the case
Периметр ромба равен 8 м.
Объяснение:
В ромбе диагонали взаимно перпендикулярны и являются биссектрисами углов. Следовательно ∠KEL = ∠EKL.
∠EOA = ∠EKL (дано). =>
∠KEL = ∠EAO => треугольник EOA равнобедренный.
Кроме того, АВ║LK║EF (так ∠EOA = ∠EKL соответствкнные углы при АВ и LK и секущей ЕК).
Значит ЕА = АО =1м.
АО = ОВ (так как точка О - точка пересечения диагоналей ромба).
AEFB - параллелограмм (так как АВ║EF и EA║FB). =>
EF =AB = 2·AO = 2 м.
Итак, сторона ромба равна 2м, тогда его периметр равен 8м (стороны ромба равны).
