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

sinA =5,25/14 (геом определение синуса)
x/sinA =2*8 (т синусов) => x =16*5,25/14 =6
3)
x+3 =y+2 (описанный ч-к) => y-x=1
Диагональ по т косинусов; cos120= -0,5; cos60=0,5
x^2 +y^2 +xy =9 +4 -2*3*2*0,5 =7
(x-y)^2 =7 -3xy => 1 =7 -3xy => xy=2
(x+y)^2 =7 +xy =9 => x+y=3
4)
sinB =sin(45+30) =√2/2 *√3/2 + √2/2 *1/2 =(√6 +√2)/4
2/sin45 =AC/sinB (т синусов) => AC =2√2(√6 +√2)/4 =√3 +1
√k +1 =√3 +1 => k=3
5)
AB=a, AD=b
P =2(a+b) => a+b =9
S =ab sinA => ab =20
a^2 +b^2 =(a+b)^2 -2ab =81-40 =41
cosA = −√(1-sinA^2) = −3/5 (тупой угол)
BD^2 =a^2 +b^2 -2ab*cosA (т косинусов) =41 +40*3/5 =65
