Before you start

Review: 5 Class 7 questions

Pronouns, many/much, the, present perfect, at/on/in, modals and conjunctions: you can't build Class 8's longer sentences without them. Get 4 out of 5 right and move on; if not, take another look at the Class 7 page.

Play: you get 5 different questions every time.

Game 1

Active and passive voice

You learned: the past participle (eaten, seen) in the present perfect; and I → me, they → them in pronoun forms. Now put the two together for the passive.

In the passive, the object comes first, then a form of be + the past participle, and at the end by + the doer. The form of be follows the tense of the original sentence. See the animation here: Active and passive voice.

TenseActivePassive
Present simpleRina writes a letter.A letter is written by Rina.
Past simpleRina wrote a letter.A letter was written by Rina.
Present continuousRina is writing a letter.A letter is being written by Rina.
Present perfectRina has written a letter.A letter has been written by Rina.
Future (will)Rina will write a letter.A letter will be written by Rina.
  • If the doer is a pronoun, use its object form after by: by me, by him, by them.
  • If the doer is unknown or everyone (people, someone), the by part is left out: Bangla is spoken in Bangladesh.
  • The passive of an order starts with Let: Open the door. → Let the door be opened.

Play: choose the right passive form.

In one line

Object first + a form of be (by tense) + past participle + by + the doer in its object form.

Game 2

Narration: who said what

In Class 7: someone's own words go in quotation marks (Punctuation). Now: telling someone else those words in your own way.

In direct speech, the speaker's exact words stay inside quotation marks. In indirect speech, we report the words in our own way: the quotation marks go, and the pronouns, the tense and the time words change.

The direct speech "I am happy," said Rina becomes the indirect speech Rina said that she was happy. I becomes she, am becomes was. Direct speech “I am happy,” said Rina. Indirect speech Rina said that she was happy. I → she · am → was · no quotation marks
The speaker's "I" becomes "she", and because said is in the past, am becomes was.
What changesExamples
The tense moves one step back (when said is in the past)am/is → was, are → were, will → would, can → could, played → had played
Time and place wordsnow → then, today → that day, tomorrow → the next day, yesterday → the previous day, here → there
Questionssaid to → asked; if for yes/no questions, the same wh- word for wh- questions, and the sentence in normal order (where I lived, not where did I live)
Orders and requestssaid to → told / ordered / requested + to + verb
Universal truthsThe tense doesn't change: He said that the earth moves round the sun.

Play: choose the right indirect speech.

In one line

No quotation marks, pronouns from the speaker's side, the tense one step back, and today → that day.

Game 3

Conditional: sentences with if

You learned: present simple, past simple and will (Tense), and could, may (Modal). Now: "if … then …".

Typeif partResult partExample
Always truepresentpresentIf you heat ice, it melts.
Possible futurepresentwill + verbIf it rains, we will stay home.
Imaginarypast (were)would + verbIf I were a bird, I would fly.
  • will doesn't go in the if part: If it rains tomorrow…, not "If it will rain".
  • In imaginary sentences, use were with every subject: If I were you…
  • unless means if … not: Unless you hurry, you will be late. = If you do not hurry, you will be late.

Play: keep the two parts matching and choose the right form.

In one line

Possible: if + present, will + verb. Imaginary: if + past, would + verb. Never will after if.

Game 4

Question tag: isn’t it?

You learned: he → has, they → have (Subject and verb) and can, will (Modal). Now: a tiny question at the end of a sentence.

When we talk, we often add a short question at the end of a sentence so the listener agrees: "You're a student, aren't you?" In English this is a question tag.

A positive sentence, "You are a student", gets a negative tag, "aren't you?"; and a negative sentence, "You aren't late", gets a positive tag, "are you?". You are a student, aren’t you? + − You aren’t late, are you? − + Positive sentence, negative tag; negative sentence, positive tag
The sentence and the tag are always opposite: one positive, the other negative.
  • The sentence's helping verb goes into the tag (is, are, can, will, has), with the subject's pronoun: She can swim, can’t she?
  • With no helping verb, use do / does / did: Rina likes mangoes, doesn’t she?
  • With never, no or hardly, the sentence is negative, so the tag is positive: You never lie, do you?
  • Exceptions to remember: I am late, aren’t I? and Let’s go, shall we?

Play: choose the right tag.

In one line

Positive sentence, negative tag; negative sentence, positive tag; with the sentence's helping verb and the subject's pronoun.

Game 5

Gerund and infinitive: reading or to read?

In Class 7: after a modal, the base form of the verb (Modal). Now: which form after other verbs?

When a verb with -ing works like a noun, it is called a gerund (Swimming is fun.). to + verb is the infinitive (I want to swim.). The word before it decides which one to use.

AfterFormExample
enjoy, finish, mind, avoid, stop-ingI enjoy reading.
preposition (of, at, in, for)-ingShe is good at drawing.
want, decide, hope, plan, learnto + verbWe decided to leave.
let, makeThe base form of the verbLet me go.

Play: look at the word before, then choose the right form.

In one line

After enjoy, finish and prepositions: -ing. After want, decide, hope: to + verb. After let, make: the base form.

Game 6

Relative pronoun: who, which, whose

In Class 7: pronoun forms (I, me, my, mine) and joining two sentences (Conjunction). Now: pronouns that do the joining themselves.

"I met a boy. The boy won the prize." The two sentences can become one: "I met the boy who won the prize." Here who refers back to the noun (boy) and also joins the two parts.

WordUsed forExample
whoPeople (subject)The man who lives next door is a doctor.
whomPeople (object)He is the teacher whom we all respect.
whichThings or animalsThis is the book which I bought.
whoseWhose (belonging)I know a girl whose father is a pilot.
wherePlacesThis is the village where I was born.

that can often replace who and which: the book that I bought.

Play: is the word before the gap a person, a thing, a place, or about belonging?

In one line

People: who/whom. Things: which. Belonging: whose. Places: where.

Game 7

Changing degree: as … as

In Class 6: tall, taller, tallest (Degree of comparison). Now: saying the same thing three ways.

SuperlativeComparativePositive
Rahim is the tallest boy in the class.Rahim is taller than any other boy in the class.No other boy in the class is as tall as Rahim.
  • Equal: as + adjective + as: Mina is as tall as Rina.
  • From comparative to positive: Rina is taller than Mina. = Mina is not as tall as Rina. (The smaller one comes first.)
  • After than any other, the noun is singular: any other boy, not "any other boys".

Play: choose the sentence with the same meaning.

In one line

the tallest = taller than any other = no other … as tall as: all three say the same thing.

Game 8

Subject and verb, next step

In Class 6: one subject, so the verb takes -s (Subject and verb). Now: subjects where it's hard to tell singular from plural.

  • each, every, everyone, nobody are always singular: Each of the boys has a bag.
  • one of + plural, but the verb is singular, because the real subject is one: One of my friends lives in Rajshahi.
  • news, mathematics: they look plural but are singular: The news is good.
  • either … or, neither … nor: the verb agrees with the nearer subject: Neither the teacher nor the students are here.
  • The number of + plural → singular verb; A number of (many) + plural → plural verb.

Play: find the real subject.

In one line

Find the real subject: each, every, one of, the number of and news take a singular verb.

Game 9

Word formation: un-, dis-, -ful, -ness

In Class 7: abstract nouns (Kinds of noun). Now: new words made by adding small parts before or after a word, such as kind → kindness.

PartWhat it doesExamples
un-, dis-, im-, in-, ir-Opposite meaning (prefix)unhappy, dishonest, impossible, incorrect, irregular
-ness, -ship, -ityabstract nounkindness, friendship, ability
-er, -orSomeone who does the actionsinger, teacher, actor
-ful, -lessAdjective: full of / withoutcareful, careless, harmless
-lyadverbbeautifully, slowly

Work out which form the sentence needs from the job of the gap: an adjective before a noun, an adverb after a verb to say how, a noun after his/her/the.

Play: choose the right form of the word in brackets.

In one line

Added before (un-, dis-, im-), the meaning turns opposite; added after (-ness, -ful, -ly), the word's job changes.
