Contrastive Conjunction and Modal Perfect

Types of conjunction

Different types of conjunctions link information in different ways. It is important to know which conjunctions establish which types of links.

There are five main types of conjunction in English.

1. Conjunctions of addition and replacement

Additive conjunctions simply add more information to what is already there. Examples of additive conjunctions include:

and, also, in addition, not only … but also, moreover, further, besides.

Example

The study used a small sample only and was strongly criticized for this reason. Furthermore, the initial premise of the research was considered questionable in the light of previous evidence.

Conjunctions of replacement replace one piece of information with another. That is, they offer an alternative. Conjunctions of replacement include the words:

or, or else, alternatively.

Example

The results could be interpreted to mean that high levels of protein are beneficial to diet generally. Alternatively, they could also mean that high protein levels are only beneficial to severely overweight males.

2. Conjunctions of comparison, contrast and concession

Comparative conjunctions are used to link two ideas that are considered to be similar. Comparative conjunctions include the terms:

in the same way, likewise, just as, both… and.

Example

Reading aloud to young children stimulates their interest in books. Similarly, visiting libraries or book fairs has been shown to increase children’s readiness to engage with print.

Contrastive conjunctions link two ideas that are considered to be different. Examples of contrastive conjunctions include:

but, however, in contrast, on the contrary, instead, nevertheless, yet, still, even so, neither …nor.

Example

This evidence points clearly to a fall in the number of unemployed. On the other hand, anecdotal evidence from reputable charities suggests that the number of people seeking financial support has increased.

Concessive conjunctions are a subgroup of contrastive conjunctions. They are used to contrast one idea with another where one piece of information appears to be surprising or unexpected in view of the other idea. Examples of concessive conjunctions include:

though, although, despite, in spite of, notwithstanding, whereas, while.

Example

Even though money has been poured into literacy programs, literacy levels among 12-15 year olds do not appear to be improving. 

Perfect Modal Verbs

modal verb + have + past participle

The Future Perfect Tense

Unlike all the other modals above, will is used for the future:

Subject + will + have + past participle

Singular	Plural
I will have lived	We will have lived
You will have lived	You will have lived
He will have lived
She will have lived	They will have lived
It will have lived

This is a difficult tense to use. It describes an action that will be completed in the future.

For example: I moved to Minnesota in 1991. The year now is 2008. By 2011, I will have lived in Minnesota for 20 years.
