FCE Use of English Part 2, Bats

Answers and explanations

9. as. ‘To portray as’ is to show. Can be used in the sense of creating the wrong impression, like in this case.
10. start/begin. The previous sentence suggests that next we are going to be presenting arguments against something. ‘To start/to begin with’ is a great way to introduce such an argument.
11. in. ‘To be different in size/shape/colour…’ – a commonly used structure. ‘To differ with’ is wrong, as it means difference with somebody or something else, e.g. ‘Me and Tom differ in our approach to studying’.
12. so. The idea is that they are very small—so small that they can be held in a hand.
13. on. ‘To feed on something’ is to eat something. ‘Feed with’ is incorrect as it means giving somebody particular food, e.g. ‘You should not feed cats with food that is too salty or spicy’.
14. of. ‘To get rid of something’ means to make it go away, normally used with something negative.
15. say. To show that something is more important (or, in this case, more impressive) than it seems. ‘Tell’ does not make the set phrase, so it should not be chosen.
16. without. ‘To bump into something’ here means to hit something without meaning to. The sentence explains the ability of bats to navigate the caves without hitting the walls.
