Always

Typical mistakes: 

Always I ask myself what I am doing here. 

Never I find the answers. 

'Always' does not normally at the beginning of a sentence.' It's usually put with the verb, in same position as other frequency adverb. 'Never' goes in the same place. 

I always ask myself what I'm doing here. I never find the answer. 

But note that 'always' can be put at the beginning of imperative sentences. 

Always put on your safety belt when you drive. 

When 'always' mean 'all through the past until now', it is usually used with a present perfect tense. 

I've always believed he was innocent. 

You've always been my closest friend. 

Along

Typical mistakes: 

All along the journey she kept complaining. 

Along the story, we learn how...

'Along' is used with nouns like road, river, corridor, line: words that refer to things with a long, thin shape. 

I saw her running along the road. 

His office is along the corridor. 

With more abstract words (or nouns that refer to time or activities), we use 'through'. 

Right through the meal...

Through the story, we learn how...

All through the journey... 

With words that refer to time, the structure 'all...long' is used. 

I'd like to live somewhere where the sun shines all year long. 

I could sit and look at you all day long. 

Also notice the special use of 'along' as an adverb in expression like 'Come along' (= Come with me) or 'walking along (= walking on one's way). 

Almost Vs Nearly

1. 'Nearly' and 'Almost' have similar meanings, and in many cases the can both be used without much difference. Usually, 'almost' is used to mean that something is a little 'nearer' than 'nearly'. E.g. So at 12:15 we might say 'It is nearly lunchtime', and at 12:27 'It's almost lunchtime'. 

We are nearly there.             We're almost there. 

S/he is nearly six feet tall.     She's almost six feet tall. 

I nearly as clever as you.         I am almost as clever as you. 

I nearly fell off my bike.          I almost fell off my bike. 

2. Typical mistakes: 

My aunt's got a strange way of talking. She nearly sounds foreign. 

It is nearly incredible. 

I nearly think you're right. 

Our cat understands everything - he's nearly human. 

In these sentences, we are not talking about progress towards an end (people do not get more foreign; cats do not get more human), or about thinks that are easy to measure. In cases like these 'almost', not 'nearly', is used. 

Our cat understands everything - he's almost human. 

I almost think you're right. 

It's almost incredible. 

My aunt almost sounds foreign. 

In that long dress she looks almost graceful (Not: ...nearly graceful). 

Note that 'nearly' is not often used with 'never', 'nobody', 'no-one', 'nothing', 'nowhere', 'no' and 'none'. Instead, we used 'almost', or we used 'hardly' with a non-negative form. 

Almost no money     hardly any money 

Almost nobody         hardly anybody 

Almost never             hardly never 

Allow Vs Permit Vs Let

Typical mistake: It is not allowed to smoke in the lecture hall. 

1. All and Permit

These words have similar meaning and uses. 'Permit' is a little bit more formal; 'allow' is more common in informal English. Both words can be followed by object + infinitive: 

We do not allow/permit people to soke in the lecture hall. 

When there is no personal object, a gerund (-ing form) is used. 

We do not allow/permit smoking in the lecture hall. 

In passive sentences, personal subjects and gerund subjects are both possible. 

People are not allowed/permitted to smoke in the lecture hall. 

Smoking is not allowed/permitted in the lecture hall. 

The 'impersonal' passive structure cannot be used with 'allow'. 

Allow (but not permit) can be used with adverb particles: 

She wouldn't allow me in. 

Mary isn't allowed out at night. 

2. Let 

'Let' is the least formal of these three words. 'Please allow me to buy you a drink' sounds polite and formal; 'Let me buy you a drink' sounds friendly and informal. 

'Let' is used in a different conversation from 'allow' and 'permit'; it is followed by 'object + infinitive without to. 

Let me help you. 

'Let' is not usually used in the passive; it is replaced by 'allow'. 

I wasn't allowed to pay for the drinks. 

Agree

1. Typical mistakes: 

I am agree with you. 

We not agree. 

'Agree' is a b verb, not an adjective. 

I agree with you. 

We don't agree. 

2. 'Agree' can be used with an infinitive or a 'that-clause'. 

He agreed to send me a cheque (Not: He agreed sending me...). 

She agreed that I was right. 

3. Several prepositions are possible, depending on the meaning and context. 

a. You agree about a subject of discussion: 

 They never agree about politics. 

b. You agree on a matter for decision: 

 Can we agree on a date for the next meeting? 

c. You agree to a proposal: 

He's agreed to our suggestion about the holiday. 

d. You agree with an opinion, an idea, an analysis, an explanation, etc: 

I completely agree with your views on Jolie. 

e. You agree with a person: 

It's a good idea to agree with the boss most of the time. 

4. A passive structure in possible with plural subject; this is rather formal: 

Are we all agree, gentlemen? 

The committee are agreed that it would be a mistake to speed any more money on the project. 

 

 

 

 

 

 

 

Age

Typical mistakes: 

He has thirty-five. 

He is thirty-five years. 

He's thirty-five old. 

You can give your age either by just giving the number, or by giving the number plus the expression 'years old'. Note the use of 'Be', without preposition. 

He's thirty-five. 

He's thirty-five years old. 

Note that 'What's your age?' is not a very common expression except in a formal style. People usually say 'How old are you?'
