Teacher's Insight

What this unit is really testing

Unit 7 pairs two texts that make the same argument from opposite sides. Parents shows what happens when someone lies about who they are online. Cyber Security shows the reader how to prevent that situation. The SEE paper uses paired texts like these to check whether a student can move between a story and an instructional article in the same unit.

The key moment in Parents is not the lie. It is the silence between the two families. The father fears a fake girl. The mother fears a strange man. Neither speaks to the other and the meeting fails. Any question about theme, character or inference in this unit comes back to this point.

Exam weight of this unit. Articles and modals together carry eleven marks in the Grammar section. Unit 7 is one of the highest-yield grammar units in the textbook.

Common Mistakes

Errors seen in real SEE scripts

  • obsessed and overprotective. Obsessed describes a mental fixation. Overprotective describes a pattern of behaviour. Question (b) in Reading I tests the difference.
  • Chronological order in Reading I, Part B. The correct sequence starts with the Facebook chat, not the car ride.
  • a ewe and a one-dimensional. Both start with a vowel letter but a consonant sound. The correct article is a, not an.
  • the Netherlands, Everest and the Nile. Countries with plural names take the. Mountain peaks take no article. Rivers take the.
  • Newspaper article in Writing II. Needs a headline, lead sentence, short paragraphs and a closing line.
  • Apology email in Writing I. The format is To, From, Subject, Salutation, Body, Sign-off and Name.

Grammar I: Modals

Modals are helping verbs. They sit before the main verb and change the strength of what the speaker is saying. Three modals matter in this unit. Each one carries a different level of force. The exam tests whether you can identify the level and choose the correct modal for the meaning.

Rule formula

Subject + modal + base verb + object.

Example: You + should + raise + your voice.

Table of forms

ModalMeaningExample
shouldAdvice. A soft suggestionYou should rest.
should notAdvice against somethingYou should not lie.
ought toMoral obligation. A dutyYou ought to help elders.
ought not toMoral duty against somethingYou ought not to cheat.
mustCompulsion. A rule with no choiceYou must wear a seatbelt.
must notProhibition. A rule against somethingYou must not smoke here.

How to solve Part A

Part A asks you to classify each sentence as advice, moral obligation or compulsion. Read the sentence and ask what the speaker is doing.

  • If the sentence can be refused without breaking a rule, it is advice.
  • If the sentence describes a duty toward others, it is moral obligation.
  • If the sentence describes a rule that removes choice, it is compulsion.

Example from this unit. You should raise your voice against discrimination is advice. You must abide by the traffic rules is compulsion. You ought to be fair in your judgment is moral obligation.

How to solve Part B

Use the meaning first, then check for negatives.

  • Use should when the sentence gives advice or a suggestion.
  • Use ought to when the sentence states a duty.
  • Use must when the sentence states a rule or compulsion.
  • Use must not to forbid. Use should not to advise against. Use ought not to for moral duty against something.

Worked example

Suppose the sentence is "Every child ___ take good care of their aging parents." The meaning is a duty that removes choice. The subject is every child, a general rule. The correct modal is must.

Suppose the sentence is "You look ill. You ___ see a doctor." The meaning is a suggestion that can be refused. The correct modal is should.

Common traps

  • Do not put to after should or must. Only ought takes to. Ought to go, not should to go.
  • Do not use do not with ought. The negative is ought not to.
  • Do not confuse must not with need not. Must not means forbidden. Need not means not necessary.
  • Do not change the tense of the sentence. The modal is the only change required.

Grammar II: Articles

An article sits before a noun and tells the reader whether the noun is general or specific. English has three articles and one case with no article at all. The exam tests whether you can hear the sound of the next word, not just see the letter. Articles appear in the multiple choice in context section almost every year.

Rule formula

Article + adjective + noun.

Example: an + honest + officer.

Table of forms

ArticleUseExample
aBefore a singular countable noun that begins with a consonant sounda book, a university, a ewe
anBefore a singular countable noun that begins with a vowel soundan apple, an hour, an honest man
theWhen the noun is specific and already knownthe window, the Nile, the Himalayas
no articleBefore uncountable nouns, abstract nouns, proper nouns, mountain peaks, meals, gameswater, honesty, Everest, breakfast, badminton

The sound test

The choice between a and an depends on sound, not on the letter. Say the word aloud. If the first sound is a vowel sound, use an. If the first sound is a consonant sound, use a.

  • a ewe. The letter is a vowel but the sound is yoo. Use a.
  • a one rupee coin. The letter is a vowel but the sound is wun. Use a.
  • a European. The letter is a vowel but the sound is yoo. Use a.
  • an hour. The letter is a consonant but the sound is our. Use an.
  • an honest man. The letter is a consonant but the sound is onest. Use an.

Worked example

Suppose the sentence is "He is ___ honest officer." The next word is honest. The letter h is a consonant but the sound is onest. A vowel sound. The correct article is an.

Suppose the sentence is "This is ___ biggest fish I have ever caught." The word biggest is a superlative. Superlatives always take the. The correct article is the.

Fixed patterns

  • Rivers, seas, oceans, mountain ranges and groups of islands take the. The Nile, the Himalayas, the Netherlands.
  • Mountain peaks, most countries, cities, streets and lakes take no article. Everest, Nepal, Kathmandu, New Road.
  • Meals, games and languages take no article. Breakfast, badminton, English.
  • Unique things take the. The sun, the moon, the president, the sky.

Common traps

  • Do not choose an only because the next word starts with a vowel letter. Choose by sound.
  • Do not use the before plural nouns when speaking generally. Say books are useful, not the books are useful.
  • Do not use the before abstract nouns. Say honesty is important, not the honesty is important.

Subject: Apology for not attending the wedding

Dear Sambridhi,

I hope this email finds you well. I am writing to express my sincere apologies for not being able to attend your brother's wedding ceremony.

I was very excited to be a part of such a joyous occasion. Unfortunately an urgent family business came up suddenly and I had no choice but to attend to it immediately. It was something that required my presence and could not be postponed.

I feel terrible for missing such an important event in your family. I had been looking forward to celebrating with you and sharing your happiness. Please convey my best wishes to your brother and his new wife. I hope they have a wonderful married life ahead.

Once again I am truly sorry for my absence. I hope you understand my situation. Let us catch up soon when I am back.

Yours sincerely,
Niti

Reading II: Cyber Security

Modern life is fundamentally intertwined with the internet. The more accounts and devices we have the greater the potential is for criminals to access our personal information. We should use complicated passwords and store them in an encrypted file. We must protect personal information offline. We should shield the PIN pad and learn to spot a credit card skimmer. Enabling two factor authentication prevents hackers from accessing our accounts. We should not reveal personal details online and should accept friend requests only from familiar people.

Writing II: Answer Key

Answer:

Internet and Cyber Security


The internet has become an inseparable part of modern life. It is fundamentally intertwined with nearly every daily task we perform. Almost everyone owns multiple devices and the more accounts we have online the greater the potential is for criminals to access our personal information.


The internet has made our lives easier. We can connect with friends access information instantly and conduct financial transactions online. However the internet also has its dark side. People fake their identities online to deceive others. Hackers try to steal sensitive information and certain vulnerable groups like children face particular concerns.


Protecting our data privacy is essential. We must use strong passwords and enable two factor authentication. We should avoid unsecured public wifi and surf only through secure websites. We should shield the PIN pad when making purchases and back up important data regularly.


In conclusion the internet is a powerful tool but comes with risks. By following basic safety tips we can enjoy its benefits while keeping our personal information secure.
