Companies now realize that consumers want products that will not only work effectively, but also save money. For most North American households, lighting accounts for 10 percent to 15 percent of the electricity bill. However, this amount can be reduced by replacing an ordinary 100-watt light bulb with an energy-saving bulb. These bulbs use a quarter of the electricity of standard bulbs and last eight times longer. Therefore consumers can save about US$7 to US$21 per bulb. In Europe, there is a labeling scheme for refrigerators, freezers, washing machines and tumble dryers. The label tells the consumers how much energy efficiency each model has, compared with other appliances in the same category. Ultimately, these innovations will save money as well as conserve the Earth’s resources.II. Readingb. Answer the questions: 1. What are Western consumers interested in? 2.

Phrasal verbs (Cụm đông từ / động từ kép) Phrasal verbs (Cụm động từ/ động từ kép) : Định nghĩa + cấu tạo:- Cụm động từ (động từ kép) là sự kết hợp giữa một động từ và một hoặc hai particle ( tiểu từ) (tiểu từ có thể là 1 giới từ, 1 trạng hoặc bao gồm 1trạng từ và 1 giới từ) theo sau Form: Phrasal verb = verb + particle preposition adverb adverb + preposition Ex: - run (v) : chạy - run into (v); gặp tình cờ (preposition)Ex: - hang (v) : treo - hang out (v): đi lang thang (adverb)Ex: - put (v): đặt, để - put up with (v) : chịu đựng ( adv) (pre)- Nghĩa của một động từ kép thường khác hoàn toàn với nghĩa của động từ gốc. Đôi khi một động từ kép còn có nhiều nghĩa. Ex: Turn off the lights before leaving our classroom Ex: You’re walking to fast. I can’t keep up with you.Lưu ý: Cụm động từ ( động từ kép) được chia ra làm hai loại: 1. Một số cụm động từ (động từ kép) có thể phân tách ( separable phrasal verbs) ( Khi cụm động từ có tân ngữ (object) thì trong một số trường hợp tân ngữ có thể đứng ở cả hai vị trí: trước hoặc sau tiểu từ.) Ta có thể nói Ex1: I turned off the light before leaving home. hay ( I turned the light off before leaving home.) Ex2: Lisa switched on the radio Lisa switched the radio on. Nếu tân ngữ là đại từ ( this, that, it/ them/ me/ him ) thì đại từ này sẽ đứng ở giữa động từ và ‘particle’: Ex: I turn it off. (Không dùng: I turn off it.) Ex: The baby is asleep. Don’t wake her up.2. Một số động từ kép không thể phân cách ( inseparable phrasal verbs): túc từ luôn luôn đứng sau giới từ. Ex: They grew up in England. Ex: Our car broke down and had to be towed to a garage. Ex: I really look up to my father * Một số intransitive phrasal verbs thông dụng: break down, break into, come back, fall through, get over ( vượt qua), get up, go on, grow up, look for ( tìm kiếm) , look up (tra nghĩa của từ), look out ( coi chừng) , look after, show up ( xuất hiện) ,sit down, stand up, stay on, watch out LF2 /p63 Match the phrasal verbs with the correct pictures.turn offturn offturn onlook forlook afterLF 2/p63 Complete the sentences.
