19-1 Connectives That Express Cause and Effect, Contrast, and Condition
Using Because of and Due to
(a) Because the weather was cold, we stayed home. Because introduces an adverb clause; it is followed by a subject and verb, as in (a).
(b) Because of the cold weather, we stayed home.
(c) Due to the cold weather, we stayed home.
Because of  and due to are phrasal prepositions, they are followed by a noun object, as in (b), (c).
(d) Due to the face that weather was cold, we stayed home. Sometimes, usually in more formal writing, due to is followed by a noun clause introduced by the fact that.
(e) We stayed home because of the cold weather.
     We stayed home due to the cold weather.
     We stayed home  due to the fact that the weather was cold .
Like adverb clauses, these phrases can also follow the main clause, as in (e).
19-2 Using Transitions to show cause and effect: Therefore and consequently
(a) Al failed the test because he didn't study.
(b) Al didn't study. Therefore, he failed the test.
(c) Al didn't study. Consequently, he failed the test.
Positions of A Transition. (a), (b), and (e) have the same meaning. Therefore and Consequently mean "as a result." In grammar, they are called transitions ( or conjunctive adverbs). Transitions connect the ideas between tow sentences.
(d) Al didn't study. Therefore, he failed the test.
(e) Al didn't study. He, therefore, he failed the test.
(f) Al didn't study.  He failed the test, therefore.

Positions of A Transition.
transition + S + V (+ rest of sentence)
 S + transition +V (+ rest of sentence)
S + V (+ rest of sentence) + transition


(g) Al didn't study, So he failed the test.
 

A transition occurs in the second of two related sentences. Note the patterns and punctuation in the examples. A period (not a comma) is used at the end of the first sentence. The transition has several positions in the second sentence. The transition is separated from the rest of the sentence by commas.
Compare: A transition (therefore) has several possible positions within the second sentence of the pair, as in (d), (e), and (f). A conjunction (so) has only one possible position: between the two sentences. So cannot more around in the second sentence as therefore can.

19-3 Other ways of Expressing Cause and Effect: Such... That and So... That

(a) Because the weather was nice, we went to the zoo.
(b) It was such nice weather that we went to the zoo.
(c) The weather was so nice that we went to the zoo.

Examples (a), (b) and (c) have same meaning.

(d) It was such good coffee that I had another cup.
(e) It was such a foggy day that we couldn't see the road.
Such...that encloses a modified noun:
Such + adjective + noun + that
(f) The coffee is so hot that I can't drink it.
(g) I'm so hungry that I could ear a horse.
(h) She speaks so fast that I can't understand her.
(i) He walked so quickly that I couldn't keep up with him.
So...that encloses an adjective or adverb:

So + adjective or adverb + that

(j) She made so many mistakes that she failed the exam.
(k) He has so few friends that he is always lonely.
(l) She has so much money that she can buy whatever she wants.
(m) He had so little trouble with the test that he left twenty.
So...that is used with many, few, much, and little.
(n) It was such a good book (that) I couldn't put it down.
(o) I was so hungry (that) I didn't wait for dinner to eat.
Sometimes, primarily in speaking, that is omitted.

19-4 Expressing purpose: Using so that

(a) I turned off the TV in order to enable my roommate to study in peace and quiet.
(b) I turned off the TV so (that) my roommate could study in peace and quiet.
 
In order to expresses purpose. In (a): I turned off the TV for a purpose. The purpose was to make it possible for my roommate to study in peace and quiet.
So that also expresses purpose. It expresses the same meaning as in order to. The word "that" is often omitted, especially in speaking.
So That + can or could:
(c) I'm going to cash a check so that I can buy my textbooks.
(d) I cashed a check so that I could buy my textbooks.

 

So that is often used of in order to when the idea of ability is being expressed. Can is used in the adverb clause for a present/future meaning.
In (c): So that I can buy = in order to be able to  buy.
Could is used after so that in past sentences.
So that + will/simple present or would:
(e) I'll take my umbrella so that I won't get wet.
(f) I'll take my umbrella sot that I don't get wet.
(g) Yesterday I took my umbrella so that I wouldn't get wet.
 
In (e): So that I won't get wet = in order to make sure that I won't get wet.
In (f): It is sometimes possible to use the simple present after so that in place of will; the simple present expresses a future meaning.
Would is used in past sentence; as in (g).

19-5 Showing Contrast (Unexpected Result)

Adverb Clauses: even though, although, though
(a) Even though it was cold, I went swimming.     (b) Although it was cold, I went swimming.
(c) Though it was cold, I went swimming.
Conjunctions: but... anyway, but...still, yet...still
(d) It was cold, but I went swimming anyway.  (e) It was cold, but I still went swimming .
(f) It was cold, yet I still went swimming .
Transitions: nevertheless, nonetheless, however...still
(g) It was cold. Nevertheless, I went swimming . (h) It was cold; nonetheless, I went swimming .
(i) It was cold. However,  I still went swimming .
Preposition: despite, in spite of, despite the fact that, in spite of the face that
(j) I went swimming despite the cold weather.  (k)  I went swimming  in spite of  the cold weather.
 

19-6 Showing Direct Contrast

Adverb Clauses: while, whereas
(a) Mary is rich, while John is poor.     (b)  Mary is rich, whereas John is poor.
(c)  Whereas  Mary is rich, John is poor.
Conjunction: but
(d) John is poor, but Mary is rich.
(e) Mary is rich, however, John is poor.   (f) John is poor; Mary is rich, however.
(j)
Mary is rich.  John, on the other hand, is poor. 

19-7 Expressing Conditions: Using otherwise and or (else)

Adverb Clause:
(a) If I don't eat breakfast, I get hungry.
(b) You'll be late if you don't hurry.
(c) You'll get wet unless you take you umbrella.

 
If and unless state conditions that produce certain results.
Transition:
(d)
I always eat breakfast. Otherwise, I get hungry during class.
(e) You'd better hurry. Otherwise, you'll be late.
(f) Take your umbrella. Otherwise, you'll get wet.
Otherwise expresses the idea "if the opposite is true, then there will be a certain result."

In (d): otherwise = if I don't eat breakfast.

Conjunction:
(g) I always eat breakfast, or (else) I get hungry during class.
(h)
You'd better hurry, or (else) you'll be late.
(i) Take your umbrella, or (else) you'll get wet.
Or else and otherwise have the same meaning.
