Linking words

The first and second parts of the documents on linking words are hereby available.  You can also find the key for the exercises here.  As you do the exercises, please remember the following three types of linking words we have identified:

• Linking words that connect two parts of the same sentence as in the following example: We only have one week off for Easter, so we will be staying in Brussels.
• Linking words that connect two separate sentences as in the following four examples, which are different ways of saying the same thing:

1. We only have one week off for Easter.  Therefore, we will be staying in Brussels.
2. We only have one week off for Easter; therefore, we will be staying in Brussels.
3. We only have one week off for Easter.  We will, therefore, be staying in Brussels.
4. We only have one week off for Easter; we will, therefore, be staying in Brussels.

• Linking words that are covered under both the first and second types as in the four following examples:

1. Besides giving his friend a lift after work, he helped her with her grocery shopping.
2. He helped his friend with her grocery shopping, besides giving her a lift after work.
3. I am afraid I am not allowed to help you with that question.  Besides, I do not know the answer myself.
4. I am afraid I am not allowed to help you with that question; besides, I do not know the answer myself.

Note that the meaning of the word 'besides'  in the first two examples is different from its meaning in the last two examples.

In all these examples, please pay special attention to the punctuation.

Position of adverbs

Here are the main rules and exceptions on the position of adverbs in sentences:

First rule: if there is only one verb in the sentence, the adverb comes before the verb as in the following example: He usually comes to work on time.
Exception to the first rule: if the only verb in the sentence is 'to be', the adverb comes after the verb as in the following example:  He is usually on time.

Second rule: If there is more than one verb in the sentence, the adverb comes after the first verb as in the following example: He has already arrived at work.
First exception to the second rule: if the first verb in the sentence is an auxiliary verb with 'to', i.e., have to, need to, ought to and used to, the adverb comes before the first verb as in the following example: He usually has to start working by 9:30 AM.
Second exception to the second rule: if the first verb in the sentence is a contracted negation, the adverbs 'probably', 'possibly' and 'certainly' come before the first verb as in the following example: He probably won't come to work on time.

These being the main rules and exceptions, there is more to this topic.  You can find more information on this webpage, which also provides you with some exercises.
