PART 1: ADVANCED SENTENCE STRUCTURES & EMPHASIS
I. ADVANCED STRUCTURE NÓI CHUNG
To communicate complex ideas effectively, you need more than simple
clauses. A variety of syntactic choices—such as inversion, cleft
constructions, and nuanced linking devices—can deliver nuance and
emphasis.
II. INVERSION FOR EMPHASIS
Inversion is when we reverse the typical subject–verb order for stylistic
or emphatic purposes. Instead of “I had never seen such chaos,” we get:
•
Never had I seen such chaos.
This adds dramatic tension and signals something out of the
ordinary.
1. NEGATIVE ADVERBS & PHRASES
•
•
•
Never had they considered the consequences.
Seldom do we witness such bravery.
Under no circumstances should you reveal this information.
USAGE TIP
Inversion after these negative elements highlights the exceptionality. It’s
common in writing (formal or literary) but can also appear in spoken
contexts for emphasis.
2. CONDITIONAL INVERSION
Conditionals sometimes allow for an inverted structure:
•
•
•
Should you require assistance, please contact us.
Had I known earlier, I would have acted differently.
Were they to make an exception, the policy would lose its
meaning.
Each of these replaces an “if” clause:

(If you should require assistance…)
(If I had known earlier…)
(If they were to make an exception…)
3. “ONLY” + TIME/CONDITION PHRASES
•
•
Only when the meeting was over did they realize the severity of
the issue.
Only after weeks of research did she discover the truth.
Here, “only when/after” triggers an inverted main clause:
•
•
…did they realize…
…did she discover…
Khi áp dụng cấu trúc đảo ngữ, hãy đảm bảo bạn nắm vững thì (tense)
của động từ. Ví dụ, nếu câu gốc dùng Present Perfect, phần đảo ngữ
vẫn cần giữ đúng dạng hoàn thành; bạn chỉ đảo trợ động từ hoặc modal.
Điều này giúp bạn duy trì sự chính xác về ngữ pháp.
III. CLEFT SENTENCES FOR FOCUS
Cleft sentences let you split one idea into two clauses, shining a
spotlight on a specific element. They often use patterns like It is/was…
that… or What… is/was….
1. “IT IS/WAS … THAT/WHO …”
•
•
IT WAS YOUR PERSISTENCE THAT SAVED THE PROJECT.
IT IS HONEST FEEDBACK THAT FOSTERS IMPROVEMENT.
This structure draws direct attention to “your persistence” or “honest
feedback.”
VARIATIONS
•
•
IT WAS my colleague WHO IDENTIFIED THE FLAW.
IT’S the final detail THAT EVERYONE OVERLOOKS.
2. “WHAT… IS/WAS…”
•
•
WHAT TRULY MATTERS IS CONSISTENT EFFORT.
WHAT THEY ALL MISUNDERSTOOD WAS THE TIMING.
FOR EDUCATIONAL PURPOSES ONLY.
NGUYEN HOANG HUY

Focus is shifted onto the subject after “what.” Great for emphasizing
abstract concepts.
Khi dùng cleft sentences, bạn có thể nhấn mạnh một đối tượng hay sự
kiện trong câu một cách tự nhiên. Đừng lạm dụng, vì nếu câu nào cũng
cleft, người đọc sẽ thấy nặng nề. Tốt nhất là luân phiên với các cấu trúc
khác để giữ bài viết linh hoạt.
IV. NOMINALIZATION & COMPLEX CLAUSES
Nominalization is turning a verb or adjective into a noun form to
create more formal or academic-sounding sentences (though be wary of
overuse).
1. EXAMPLE OF NOMINALIZATION
•
•
Standard (verb-based): They decided to investigate the issue.
Nominalized: They made a decision to conduct an
investigation into the issue.
While the second might seem more formal, it can also slow clarity if used
too often.
2. COMPLEX RELATIVE CLAUSES
Instead of short sentences, advanced English often employs relative
clauses to merge ideas:
•
THE PROPOSAL, which WAS INITIALLY SEEN AS TOO
COSTLY, EVENTUALLY GAINED UNANIMOUS APPROVAL.
Here, which was initially seen as too costly is extra information
about the proposal. If it’s essential info, no commas are used: THE
PROPOSAL THAT THE BOARD REJECTED LAST WEEK HAS BEEN
REVISED.
Để tạo liên kết tự nhiên giữa các ý, relative clause là phương tiện hiệu
quả, miễn là bạn nắm rõ các đại từ quan hệ (WHO, WHICH, THAT,
WHOSE…) và khi nào dùng dấu phẩy (non-restrictive) hoặc khi
nào không (restrictive).
PART 2: PERFECT TENSES & ADVANCED MODAL USAGE

I. PERFECT TENSES IN GREATER DEPTH
1. PRESENT PERFECT VS. PRESENT PERFECT CONTINUOUS
•
•
Present Perfect (HAVE/HAS + PAST PARTICIPLE)
o I HAVE FINISHED THE REPORT.
o Implies the action is complete at the moment of speaking.
Present Perfect Continuous (HAVE/HAS BEEN + -ING
FORM)
o I HAVE BEEN WORKING ON THE REPORT SINCE
MORNING.
o Emphasizes the ongoing nature or duration of the action.
Usage Note: Người học thường nhầm lẫn hai dạng này, nhất là khi nói
về hành động còn tiếp tục. “I HAVE WRITTEN THIS BOOK FOR
THREE YEARS.” suggests you may have completed writing, whereas “I
HAVE BEEN WRITING THIS BOOK FOR THREE YEARS” clarifies it’s
still in progress. Always consider whether the action is finished or
remains ongoing.
2. PAST PERFECT & PAST PERFECT CONTINUOUS
•
•
Past Perfect (HAD + PAST PARTICIPLE)
o SHE HAD ALREADY LEFT BY THE TIME HE ARRIVED.
o Indicates a completed action before another past action.
Past Perfect Continuous (HAD BEEN + -ING)
o THEY HAD BEEN DISCUSSING THE PLAN FOR HOURS
BEFORE THEY REACHED AN AGREEMENT.
o Shows the duration or repeated nature of an action leading
up to another past moment.
You often see Past Perfect (simple) in narratives to clarify the sequence
of events. But if you want to stress how long something had been
happening before another event, Past Perfect Continuous is your go-to.
3. FUTURE PERFECT & FUTURE PERFECT CONTINUOUS
•
•
Future Perfect (WILL HAVE + PAST PARTICIPLE)
o BY NEXT MONDAY, I WILL HAVE COMPLETED ALL
REQUIRED TASKS.
Future Perfect Continuous (WILL HAVE BEEN + -ING)
o BY THE TIME HE RETIRES, HE WILL HAVE BEEN
WORKING AT THE FIRM FOR 40 YEARS.
FOR EDUCATIONAL PURPOSES ONLY.

These tenses let you talk about actions that will be completed or in
progress by a certain time in the future.
II. ADVANCED MODAL VERBS (FOCUS ON PERFECT FORMS)
Modal verbs (can, could, may, might, must, should, etc.) become more
intricate when combined with “have + past participle,” expressing
degrees of certainty, missed opportunities, or unreal
situations in the past.
1. EXPRESSING PAST POSSIBILITY & CERTAINTY
•
•
•
May have / Might have: Suggests a possibility in the past.
o HE MIGHT HAVE FORGOTTEN THE APPOINTMENT.
(Not sure if he did, but it’s possible.)
Could have: Indicates either possibility or missed
ability/opportunity.
o THEY COULD HAVE TAKEN THE EARLIER TRAIN. (But
they didn’t—an opportunity lost or a possibility ignored.)
Must have: Strong deduction about the past.
o SHE MUST HAVE LEFT ALREADY (You’re almost certain
she’s gone.)
2. EXPRESSING PAST CRITICISM, REGRET, OR ADVICE
•
•
•
Should have + V3:
o YOU SHOULD HAVE CALLED ME EARLIER. (Ngụ ý phê
bình nhẹ: “Đáng lẽ bạn nên gọi sớm hơn.”)
Ought to have + V3:
o THEY OUGHT TO HAVE BEEN MORE TRANSPARENT.
(Similar to “should have,” but can be slightly more formal.)
Would have + V3:
o I WOULD HAVE HELPED YOU IF I HAD KNOWN.
(Regret or missed conditional situation.)
3. NEGATIVE FORMS
•
•
Shouldn’t have + V3:
o THEY SHOULDN’T HAVE CANCELED THE MEETING SO
ABRUPTLY.
Couldn’t have + V3:
o HE COULDN’T HAVE COMMITTED THE CRIME; HE
WAS ABROAD. (Strong negation of possibility.)

Khi dùng “modal + have + V3,” hãy xem ngữ cảnh bạn muốn diễn đạt là
gì: khả năng, nuối tiếc, hay phê phán? Chọn từ “may/might,” “should,”
“could,” “must” sao cho phù hợp với mức độ chắc chắn hoặc ý nghĩa tiếc
nuối mà bạn muốn thể hiện.
III. COMBINING PERFECT TENSES WITH MODAL PERFECTS
Sometimes, advanced writing requires chaining these forms. You might
see expressions like:
•
•
SHE must have been waiting FOR HOURS BEFORE I
ARRIVED. (combines deduction “must have” with continuous
form “been waiting”)
THEY could have been working ON THE DESIGN
OVERNIGHT, BUT APPARENTLY THEY DIDN’T. (possibility
about ongoing past action, unfulfilled)
This layering can articulate precise meaning. For example, “HE MAY
HAVE BEEN LIVING IN FRANCE BEFORE THE MERGER” implies
possibility plus an extended duration of time in the past.
Complex Example:
•
“HAD YOU NOT RESPONDED SO QUICKLY, THE SITUATION
COULD HAVE BEEN FAR WORSE.”
o Past Perfect in the conditional clause (“Had you not
responded”) + modal perfect in the main clause (“could have
been…”) emphasizes the hypothetical scenario.
IV. SUBTLE CHOICES: WHEN TO USE A SIMPLE VS.
CONTINUOUS FORM
Sometimes either a simple or continuous perfect is grammatically viable.
The nuance:
•
•
HE MUST HAVE WORKED THROUGH THE NIGHT. → Focuses
on the end result (He’s probably done).
HE MUST HAVE BEEN WORKING THROUGH THE NIGHT. →
Emphasizes the ongoing process.
One might not be drastically “wrong,” but each conveys a subtly different
viewpoint. A continuous perfect usually highlights duration or

continuous effort, while a simple perfect highlights completion or
fact.
PART 3: SUBJUNCTIVE, MIXED CONDITIONALS & FINAL
REFINEMENTS
I. SUBJUNCTIVE MOOD
The subjunctive mood is less common in everyday English, but it still
appears in formal contexts or certain fixed expressions. It often
describes hypothetical situations, demands, or
recommendations.
1. SUBJUNCTIVE IN “THAT”-CLAUSES
You’ll see this pattern after verbs like INSIST, SUGGEST, DEMAND,
RECOMMEND and adjectives like ESSENTIAL, IMPERATIVE,
CRUCIAL:
•
•
THEY DEMANDED that SHE vacate THE PREMISES
IMMEDIATELY. (subjunctive “vacate,” not “vacates”)
IT IS ESSENTIAL THAT EVERY MEMBER attend THE
CONFERENCE.
Lưu ý: Ở mệnh đề này, động từ không đổi theo ngôi (no -s for third
person singular, no tense marker). It’s a bare form: THAT HE GO,
THAT SHE LEAVE, THAT THEY BE.
2. FIXED SUBJUNCTIVE PHRASES
•
•
•
IF I were YOU… (not “If I was you…”)
GOD SAVE THE QUEEN.
LONG LIVE THE KING.
These are idiomatic or traditional expressions. “If I were you” remains
the preferred formal usage (though “If I was you” occurs in casual
speech).
II. MIXED & COMPLEX CONDITIONALS
FOR EDUCATIONAL PURPOSES ONLY.
NGUYEN HOANG HUY

We’ve already seen first, second, and third conditionals. Mixed
conditionals combine time references, creating more nuanced “if”
scenarios.
1. COMMON MIXED PATTERNS
A) PAST → PRESENT
•
IF I had studied MEDICINE (IN THE PAST), I would be A
DOCTOR NOW.
o Action in the past that didn’t happen, affecting the present
reality.
B) PRESENT → PAST
•
IF SHE were MORE HONEST (IN GENERAL, PRESENT
TRAIT), SHE would have admitted HER MISTAKE LAST
WEEK.
o Ongoing characteristic leads to a hypothetical action in the
past.
2. LOGICAL FLOW
These forms let you express UNREAL or HYPOTHETICAL events
spanning different time frames. This is advanced because you must keep
track of each tense carefully to avoid confusion.
Practice: Write 2–3 sentences describing how a different past decision
would alter your present situation, and vice versa.
III. ADVANCED ADVERBIAL CLAUSES & EMPHASIS
1. “EVEN THOUGH,” “DESPITE,” “WHEREAS,” ETC.
Combining these with more complex structures can refine your
argument. For instance:
•
•
EVEN THOUGH THE TEAM HAD PREPARED EXTENSIVELY,
THEY ENCOUNTERED UNFORESEEN TECHNICAL ISSUES.
WHEREAS MANY COMPANIES ADOPT A TOP-DOWN
APPROACH, THIS STARTUP PRIORITIZES EMPLOYEEDRIVEN INNOVATION.

2. FRONTED ADVERBIALS FOR NUANCE
Starting your sentence with an adverbial phrase can lend emphasis or
variety:
•
•
FAR FROM BEING SATISFIED, THE COMMITTEE
DEMANDED A COMPLETE OVERHAUL.
DESPITE THE BUDGET CONSTRAINTS, THEY MANAGED TO
DELIVER ON TIME.
Just make sure you add a comma after these fronted elements to
maintain clarity.
IV. FINISHING TOUCHES: PUNCTUATION & RHETORICAL
DEVICES
1. SEMI-COLONS (;) AND COLONS (:)
•
•
Semi-colons: Link two independent but related clauses.
o SHE HAD TO FINALIZE THE DESIGN; THE DEADLINE
WAS NON-NEGOTIABLE.
Colons: Introduce a list, quote, or a further explanation.
o HE HAD ONE PRIMARY REQUIREMENT: ABSOLUTE
CONFIDENTIALITY.
2. PARALLEL STRUCTURES
Parallelism ensures stylistic elegance. Each element in a list or
comparison should match in grammatical form:
•
•
HE ADMIRES HONESTY, DILIGENCE, AND CREATIVITY. (All
nouns)
SHE SPENT HER WEEKEND READING REPORTS,
POLISHING HER PRESENTATION, AND CONTACTING
CLIENTS. (All -ing forms)
3. RHETORICAL CONTRASTS (USING “NOT ONLY… BUT ALSO”)
•
NOT ONLY DID THE SURVEY REVEAL SYSTEMIC ISSUES,
BUT IT ALSO HIGHLIGHTED POTENTIAL SOLUTIONS.
o That inversion (“Not only did… but it also…”) underscores
the dual findings.

Nhắc nhở: Việc sử dụng parallel structure hoặc rhetorical contrasts có
thể giúp bài viết trở nên thuyết phục hơn. Đừng quên kiểm tra logic để
tránh trường hợp đang “kể lể” mà lạc đề.
V. PRACTICAL EXERCISES (PART 3)
1. Subjunctive Practice:
o Write 2 sentences using RECOMMEND/DEMAND/INSIST
in a subjunctive clause. E.g., “They insist that each
participant be present at 9 a.m.”
2. Mixed Conditionals:
o Invent a scenario about your career or studies, describing a
past hypothetical that changes your present. For instance: “If
I had majored in finance, I would be working in investment
banking now.”
3. Rhetorical Emphasis:
o Use “Not only… but also…” and “Whereas…” in short
passages that compare or contrast ideas.
4. Parallel Structures:
o Create a sentence listing 3 or more actions or adjectives,
ensuring parallel grammar.
