They serve for producing flames of different intensity LESSON – Text Exercise 2: translate into English 1.Trang bị phòng thí nghiệm hóa học phụ thuộc vào loại cơng việc tiến hành Equipment/ laboratory/ vary/ nature/ work/ exist/ which / carry out Mỗi phòng thí nghiệm nên cung cấp nguồn nước, khí điện Every / laboratory / provide / water / gas / electricity Lesson 4: Grammar THE PASSIVE VOICE “Voice” refers to the way the verb is used in the sentence Remember that a sentence has to have a subject and a verb, and many verbs require direct objects Here’s an example of active voice: subject verb direct object Babe hit the baseball doer action receives action In passive voice, the subject of the sentence also receives the action The doer of the action is someone else Here’s an example of passive voice: subject The baseball receives action verb is hit action by Babe who did the action 21 Lesson 4: Grammar THE PASSIVE VOICE Correct: 250mL of distilled water was poured into a 500 mL beaker Incorrect: I poured 250mL of distilled water in a beaker (active voice) Pour 250mL water in a beaker (direction/command) Correct: The covered crucible was mounted on a ring stand Incorrect: We put the crucible on a ring stand (active voice) Set the crucible on a ring stand (direction/command) Correct: The temperature was initially measured at 80°C Incorrect: I measured the temperature at 80°C (active voice) Measure and write down the temperature (direction/command) 22 Lesson 4: Homework - Read and translate into Vietnamese text - Exercise 23 ...
