Vergul ma'noni o'zgartiradi

Bu mavzudagi eng nozik dars. Boshqa savollarda vergul to'g'ri yoki xato edi; bu yerda ikkala variant ham grammatik jihatdan to'g'ri — lekin ular boshqa narsani anglatadi.

📝 Namuna:

The bells that were recast in 1971 are rung on feast days.

→ minorada bir nechta qo'ng'iroq bor. Faqat 1971-yilda qayta quyilganlari chalinadi. Bo'lak qaysi birini aytadi.

The bells, which were recast in 1971, are rung on feast days.

→ qo'ng'iroqlar bitta guruh. Hammasi 1971-yilda qayta quyilgan, va hammasi chalinadi. Bo'lak qo'shimcha ma'lumot.

💡 Maslahat: Eng tez belgisi: that hech qachon vergul olmaydi. Agar variantlarda , that bo'lsa — u deyarli har doim xato. which esa vergul bilan keladi (bo'lak qo'shimcha bo'lganda).

Nomlar bilan ham shunday

📝 Namuna:

Her brother Karim lives in Nukus. → uning bir nechta akasi bor; Karim degani Nukusda.

Her brother, Karim, lives in Nukus. → uning bitta akasi bor, va uning ismi Karim.

Ikkovi ham to'g'ri gap. Qaysi biri kerakligini matnning qolgan qismi aytadi — masalan agar oldingi jumlada «uning yagona akasi» deyilgan bo'lsa, vergullar kerak.

Which choice completes the text so that it conforms to the conventions of Standard English?

  2. , that survives from the 1840s,
  3. , which survives from the 1840s,
  4. which survives from the 1840s

Kontekstga qarang. Birinchi jumla to'rt daftar borligini aytadi. Demak The ledger … qaysi birini nazarda tutayotganini aniqlashi kerak.

Bo'lak kerakli — u to'rttadan bittasini ajratadi. Demak vergul yo'q, va olmosh that.

TUZOQ, which survives from the 1840s, — grammatik jihatdan to'g'ri — lekin ma'nosi boshqa: vergullar bo'lakni qo'shimcha qiladi, ya'ni «daftar (aytgancha, u 1840-yillardan)». Bu birinchi jumladagi four ledgers ga zid: qaysi biri ekani noma'lum qoladi.
TUZOQ, that survives from the 1840s,that hech qachon vergul olmaydi. Bu eng oson tanaladigan xato.

📌 Eslatma: E'tibor bering: ikkinchi variant xato emas — u boshqa gap. Bu turdagi savollarda javobni oldingi jumla beradi, grammatika emas. Kontekstsiz ikkala variant ham to'g'ri bo'lardi.
