Linkers

The first and second parts of the documents on linkers 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 linkers we have identified:

• Linkers 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.
• Linkers 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.

• Linkers 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.
