Exercise 6. In the texts about lasers you have come across such adverbs as
“considerably”, “frequently”, “continuously” etc. Let’s recollect what an adverb
is.
These are words which inform us about:
1) how something is done (quickly, slowly, carefully, on foot, by bus, etc.). These
are adverbs and adverbial phrases of manner;
2) where something is done (there, at home, in England, on Web, at work, etc.).
These are adverbs and adverbial phrases of place;
3) when something is done (yesterday, today, next week, at 5 o’clock, etc.). These
are adverbs and adverbial phrases of time.
Now, you should remember the order of these words in a sentence: it is “manner-
place-time”.
Example: Our students made this experiment successfully last week.
However this order changes as soon as we meet “movement verbs”. Then the order
is: “place-manner-time”.
Example: We went to the Computing laboratory quickly after classes.
Try this exercise:
1. I worked (at the office, hard, today).
2. I’m travelling (every summer, by bicycle, to my native village).
3. He studied (last year, a lot, at university).
4. I drive (every morning, to work).
5. The friend walked (through the park, home, this afternoon).
6. The orchestra performed (at the concert, magnificently, last night).
7. She translated the text (quickly, yesterday, at the lesson).
8. The engineers return (by plane, to France, every weekend).
