English grammar, taught properly.

Many women experience sickness; it usually a normal.

Many women experience sickness; it is usually normal.

Turkish lets an adjective stand alone – o normal. English cannot: every finite clause needs a verb, and where there is no action, be is the verb.

We recommend vaccine because it protects the baby.

We recommend the vaccine because it protects the baby.

A specific thing already in play takes the. First-mention countable takes a/an. An uncountable or a whole field takes nothing.

The contractions are every five minutes, before the patient come to hospital.

When the contractions are every five minutes, come to hospital.

Two things at once: the connector names a condition, so when, not a tacked-on before; and the patient come → comes.

The chart was worried.

The chart was worrying.

One test: who is feeling it? People take -ed. Things – charts, traces, trends, observations – take -ing.

There were three options, however Monitoring was the safest.

There were three options. However, monitoring was the safest.

However is not a joining word. It needs a full stop in front of it and a comma after. Same family as therefore and as a result.

They must be celebrating something special, I have to find a table.

They must be celebrating something special, so I have to find a table.

Russian punctuates by clause and a comma may legally join two full clauses. English punctuates by sentence.

Most of people arrive after midnight.

Most people arrive after midnight.

Two different structures. MOST + bare noun for people in general; MOST OF + THE for a specific group already named.

The queue was that bad that we left. I only work on the weekend, and I asked where the restroom was.

The queue was so bad that we left. I only work at the weekend, and I asked where the toilets were.

Three British-English corrections in one line: so … that for the result pair; at the weekend, not on; and restroom is American – in Britain ask for the toilets, or the Ladies and the Gents.

He must have been having too many drinks.

He must have had too many drinks.

The original was already right – this one was broken by over-correcting under instruction. A completed cause takes must have had; the continuous adds nothing.

It is tougher as we get older.

The older we get, the tougher it becomes.

The double comparative. He can build one – he had already produced The more action a government takes, the more progress it will make.

Living abroad is difficult, however it teaches you quickly.

Living abroad is difficult. However, it teaches you quickly.

Written Spanish tolerates the comma chain; English does not. However is an adverb, not a conjunction.

This will be resumed in one sentence.

This can be summed up in one sentence.

A false friend: Spanish resumir means to summarise. English resume means to start again after a pause.

I wanted to feel healthier so that I stopped eating sweets.

I stopped eating sweets so that I could feel healthier.

So that points at the goal, and the goal goes second. Action first, purpose after.

We went to the Paris and met the Grandma at the station.

We went to Paris and met Grandma at the station.

Proper nouns take no article – place names and family names used as names alike.

Active travel accounted for 14% and 19 in London and Tokyo respectively.

Active travel accounted for 13% and 10% in London and Tokyo respectively.

The figures belong to two other cities on the same chart – which he then quotes correctly in the next paragraph.

Governments subsidise public transport, as such reducing congestion.

Governments subsidise public transport, thereby reducing congestion.

As such means in that capacity. For a result use thereby + -ing, or thus, or and so.

The proportion of people travelling by car were the highest in every city.

The proportion of people travelling by car was the highest in every city.

The verb agrees with proportion, not with the nearest noun. Agreement breaks at exactly the distance where the subject stops being visible.

Governments should relax regulations which mitigate the responsibility of industry.

Governments should relax the regulations that oblige industry to act.

The thesis contradicted itself: regulations that mitigate responsibility are the ones he wants relaxed, which argues the opposite case.

Function returns pointer to buffer, so caller must free memory before process exits.

The function returns a pointer to the buffer, so the caller must free the memory before the process exits.

Six determiners missing from one sentence of otherwise near-native syntax. Polish has no article system, so nothing prompts them.

The traffic in my city very bad and many people angry about it.

The traffic in my city is very bad and many people are angry about it.

Arabic forms a complete sentence without a present-tense verb. English never does. Get be in place first – everything else is easier after it.

Moreover, education is a right, and it is important for everyone, and governments should pay for it.

Beyond fairness, public funding pays for itself: a better-educated workforce raises tax revenue, which offsets the initial cost.

The original asserts; the upgrade develops – claim, then mechanism, then consequence. That single move is what lifts Task Response to 7.

I sometimes do mistakes

I sometimes make mistakes

MAKE tends to go with producing or causing a result – make a mistake, make a decision, make progress, make a backup; DO goes with activities and work – do research, do a scan, do your homewo.

I read about the exploit in a forum

I read about the exploit on a forum

English chooses between on, in and at by context; the pairing has to be stored, not reasoned out.

The scanner run every hour

The scanner runs every hour

The English third-person singular -s has to be maintained deliberately: the scanner runs, it depends, she has access.

it depends of the ruleset we loaded last week

it depends on the ruleset we loaded last week

Verb + preposition pairs are stored whole, not derived: depend on, rely on.

since three days

for three days

FOR takes a duration, SINCE takes a starting point: for three days / since Monday.

You can see the misconfiguration on the screenshot I attached

You can see the misconfiguration in the screenshot I attached

English puts things in a picture, a screenshot or an image, not on one.

AI just a tool

AI is just a tool

Every English sentence needs a verb, and where there is no other verb the verb is a form of BE.

some people think pets is a part of their lives

...pets are a part of their lives

Match plural to plural: a plural subject takes a plural verb (pets are).

technology affect education negatively

technology affects education negatively

Add the -s for he/she/it: one thing → affects.

food are spicier

food is spicier

The rule underneath: food is uncountable → food is; cars is plural → cars are.

a lot of stuffs were sold

a lot of stuff was sold

Stuff is uncountable: it takes no plural -s, and it takes a singular verb.

people don't go out of Korea

people don't leave Korea / don't go abroad

English keeps go out of for small enclosed spaces – a room, a building, a lift.

at weekdays

on weekdays

AT for clock times and night (at 7, at night); ON for days and dates (on Monday, on weekdays, on my birthday); IN for months, years and longer stretches (in July, in the morning).

My friends are the same

A plural subject takes a plural verb: friends are, people are.

there is too much stuff to organise

Stuff is an uncountable noun – no plural -s, and a singular verb with it.

would have had

will have had

The future perfect is will have + past participle: it looks ahead and says something will be finished by a future point.

I am ready this lesson

I am ready for this lesson

Ready takes for before the thing you are ready for.

half year ago

half a year ago

Add a to a singular countable noun, and keep the idiom half a year (or simply six months).

they were not paying last few invoices

not paying the last few invoices

Add the when the noun is specific and identified: the last few invoices is a known, particular set.

I don't have team under me

I don't have a team under me

A singular countable noun takes a: a team, a sales team.

you should invest in sales team

invest in a sales team

First-mention singular countable nouns take a, even inside a compound: a sales team.

make a photo of yourself

take a photo of yourself

English fixes this verb as take – take a photo, take a picture – and the wider split is take a photo, make a decision, do the work, have a meeting.

I think South Eastern area of Moscow

the south-eastern area of Moscow

An of-phrase pins a noun down, so the noun it modifies takes the definite article.

he claimed Iberian peninsula will turn into a huge burden

the Iberian peninsula will turn into a huge burden

Named geographical features – peninsulas, seas, ranges – take the.

the governor of Lombardy region

the governor of the Lombardy region

they ran family business

they ran a family business

A first-mention countable noun takes a/an.

since the ancient Greece times

since ancient Greek times

Before a noun such as times, use the adjective (ancient Greek), not the country noun – and the generic time phrase takes no article.

he was not in the politics, he was behind the scenes

he was not in politics; he was behind the scenes

An abstract noun used generically takes the zero article: in politics, under pressure, with patience. And two full clauses need more than a comma – a semicolon carries the contrast.

a largest lake

the largest lake

An attributive superlative takes THE: there is only one largest, so it is definite by nature.

it's ancient palace

it's an ancient palace

A first-mention countable noun takes A/AN – and the vowel sound calls for AN.

not as big as on Christmas

not as big as at Christmas

English fixes festivals with AT: at Christmas, at Easter, at the weekend – but keeps ON for named days (on Saturday). So: at the season, on the day.

the car you're allowed to drive with 18

the car you're allowed to drive at 18

English states an age with AT: at 18, at the age of 18. WITH is never used for age.

good in English

good at English

Skills take AT: good at English, brilliant at improvising – and AT stays even when an -ing form follows.

in primetime

at prime time

Clock-like time slots take AT: at prime time, at midnight, at the interval.

everybody want to

everybody wants to

Everybody, everyone and each are grammatically singular, always.

we also works together with our business law department

we also work together with our business law department

A plural subject never takes the singular -s; this is a hypercorrection, evidence that the -s system is unstable in both directions under speed.

I don't know if that have sense in English

I don't know if that makes sense in English

A singular subject takes the -s form: that has, that makes.

a woman that practice massage

a woman who practises massage

A singular subject takes the -s form; and for a person, WHO is the natural relative pronoun – that is possible, but who reads better.

this company don't want to hire anyone

this company doesn't want to hire

With a singular subject the negative carries the -s through do-support: doesn't, didn't.
