2. Modal verbs Hedging (Softening Claims) Boosting (Strengthening Claims)
May (not), might (not), can, could, should = possibility, prediction
Should = hedged prediction
Would
Will = strong prediction
Must = high certainty or a very strong obligation
Can = ability: definitely able to do something
Cannot = will certainly not

3. May
1a. Iterations in temperature may mean greater variability in annual climatic events. 1b. Iterations in temperature mean / will mean greater variability in annual climatic events. 1c. Iterations in temperature should mean greater variability in annual climatic events.

4. Should
2. From a humanitarian standpoint, the United States government should invest resources in controlling the global spread of malaria. (This is a hedged recommendation – implications or concluding section)

5. Can
Can both hedges and boosts – adverbs clarify the meaning. 3. Credible guidelines can certainly be established. (boosting) 4. These findings can possibly be explained by earlier research. (hedging) The negatives of some modals do not have the same strength as the affirmatives. Cannot is much stronger than can; it means something is certainly impossible or must not be allowed. Have to is similar to must in strength but do not have to means something isn’t necessary.

6. Would
Would is used for a prediction or hypothesis about events or states that might happen in the future but are not currently real or possible. Would is considered a hedging device because it has an unreal meaning that distances the writer from the claim. 5. To tackle this problem would require at least three things. (no one is tackling the problem, but if someone did it would require three things) Would is used in unreal condition clauses but in academic writing often the if clause is often implicit. 6.

7. Adverbs
The strength of any verb can be hedged or boosted with an adverb. Most hedging or boosting adverbs appear in the middle of the clause they modify. The exact position depends on the verb:
Before the main verb when it is also the finite verb: The results apparently show…
Between the finite and the main verb: This has been somewhat validated by…
After be as a main verb: This is presumably why….

8. Adverbs
Actually boosts a claim – it introduces a possibility that the reader might not expect. 7. The expectation of reward can actually undermine intrinsic motivation and creativity of performance. Indeed boosts a hedged statement by showing that an idea is true even though it had been doubted. 8. Part of the answer may indeed lie in our genes. What is the effect of the combination of a hedging modal and a boosting adverb? 9. Because of past and future anthropogenic emissions of CO2, the climate may depart significantly from its natural course over the next 50,000 years
