Kirish: Shart gaplari va tabiatni asrash

Yo'qolib borayotgan hayvonlar haqida gapirganda biz doim shartlar bilan fikrlaymiz: agar brakonerlik to'xtamasa, agar o'rmonlar kesilmasa, agar odamlar vaqtida harakat qilganida... Ingliz tilida bu ma'nolar to'rt asosiy shart gap turi bilan ifodalanadi. Har bir tur ikki qismdan iborat:

If-clause (shart) + Main clause (natija)

Qismlar o'rnini almashtirish mumkin: If bilan boshlangan qism oldin kelsa, undan keyin vergul qo'yiladi; keyin kelsa, vergul kerak emas: If we act now, we will save them. = We will save them if we act now.

1-bo'lim. Zero Conditional - tabiat qonunlari

If + Present Simple, Present Simple

Har doim to'g'ri bo'lgan umumiy haqiqatlar, tabiat qonunlari va ilmiy faktlar uchun ishlatiladi. Bu turda if so'zini when bilan almashtirsa ham ma'no o'zgarmaydi:

• If a polar bear loses its sea ice, it cannot hunt seals. - Agar oq ayiq dengiz muzidan ayrilsa, tyulen ovlay olmaydi.
• If animals lose their habitat, their numbers fall quickly. - Hayvonlar yashash muhitini yo'qotsa, ularning soni tez kamayadi.
• Snakes become inactive if the temperature drops below ten degrees. - Harorat o'n darajadan pastga tushsa, ilonlar harakatsiz bo'lib qoladi.

2-bo'lim. First Conditional - real kelajak

If + Present Simple, will / won't + V1

Kelajakda yuz berishi real bo'lgan shartlar uchun. Muhim qoida: if-qismda will ishlatilmaydi, garchi ma'no kelajakka tegishli bo'lsa ham:

• If poaching continues at this speed, snow leopards will disappear from our mountains. - Agar brakonerlik shu tezlikda davom etsa, qor qoplonlari tog'larimizdan yo'qoladi.
• If the government creates more national parks, many species will survive. - Hukumat ko'proq milliy bog'lar tashkil etsa, ko'plab turlar omon qoladi.
• We won't save the Aral Sea ecosystem if we don't reduce water waste. - Suv isrofini kamaytirmasak, Orol dengizi ekotizimini saqlab qololmaymiz.

First Conditional asosiy qismida will o'rniga can, may, might, must yoki buyruq shakli ham kelishi mumkin: If you see an injured wild animal, call the rescue centre.

3-bo'lim. Second Conditional - hozirgi xayoliy holat

If + Past Simple, would / could / might + V1

Hozirgi yoki kelajakdagi real bo'lmagan, xayoliy vaziyatlar uchun. Past Simple ishlatilsa ham, ma'no o'tgan zamonga EMAS, hozirga tegishli:

• If I were the president, I would ban the ivory trade completely. - Prezident bo'lganimda fil suyagi savdosini butunlay taqiqlagan bo'lardim.
• If tigers could speak, what would they tell us? - Yo'lbarslar gapira olganida bizga nima degan bo'lardi?
• More tourists would visit our nature reserves if the roads were better. - Yo'llar yaxshiroq bo'lganida qo'riqxonalarimizga ko'proq sayyoh kelardi.

Eslatma: Second Conditional da barcha shaxslar bilan were ishlatish rasmiy va to'g'ri hisoblanadi: If I were you, If she were here. Og'zaki nutqda "If I was" ham uchraydi, lekin imtihonlarda va rasmiy yozuvda were ni tanlang. "If I were you, I would..." - maslahat berishning eng keng tarqalgan qolipi.

4-bo'lim. Third Conditional - o'tgan zamon afsusi

If + Past Perfect, would have + V3

O'tmishda yuz bermagan voqealar va ularning xayoliy natijalari uchun - afsus, tanqid yoki tahlil ohangida:

• If people had used water carefully in the last century, the Aral Sea would not have shrunk so dramatically. - O'tgan asrda odamlar suvdan ehtiyotkorona foydalanganida, Orol dengizi bunchalik keskin qurib qolmagan bo'lardi.
• The dodo would have survived if sailors had not hunted it so intensively. - Dengizchilar dodo qushini bunchalik shafqatsiz ovlamaganida, u omon qolgan bo'lardi.
• If scientists had started the breeding programme earlier, they could have saved more Przewalski's horses. - Olimlar ko'paytirish dasturini ertaroq boshlaganida, ko'proq Prjevalskiy otlarini saqlab qolishlari mumkin edi.

5-bo'lim. Mixed Conditional - aralash shart (B2)

O'tmishdagi shart hozirgi natijaga ta'sir qilganda ikki tur aralashadi:

If + Past Perfect, would + V1 (hozirgi natija)

• If humans had protected the Caspian tiger, it would still exist today. - Odamlar Kaspiy yo'lbarsini himoya qilganida, u bugun ham mavjud bo'lardi.
• If the reserve had not been created in 1970s, Bukhara deer would be extinct now. - Qo'riqxona 1970-yillarda tashkil etilmaganida, Buxoro bug'usi hozir qirilib ketgan bo'lardi.

6-bo'lim. Unless, as long as, provided that

B2 darajada if ning muqobillarini bilish talab qilinadi:

• Unless = if ... not: Unless we act now, it will be too late. (= If we don't act now...) - Hozir harakat qilmasak, kech bo'ladi.
• As long as / provided that = faqat shu shart bilan: Wild animals are not dangerous as long as you keep your distance. - Masofani saqlasangiz, yovvoyi hayvonlar xavfli emas.
• In case = ehtiyot shart: Take a camera in case you see a rare bird. - Noyob qush ko'rib qolsangiz deb, fotoapparat oling.

Maslahat: Unless dan keyin inkor ishlatmang - unless o'zi allaqachon inkor ma'nosini beradi. "Unless we don't act" - ikki marta inkor bo'lib, mantiqsiz jumla hosil qiladi. To'g'risi: Unless we act yoki If we don't act.

7-bo'lim. O'zbek o'quvchilarining tipik xatolari (interferensiya)

• Noto'g'ri: If poaching will continue, tigers will die out. -> To'g'ri: If poaching continues, tigers will die out. (O'zbekcha "davom etsa" kelajakni bildirgani uchun o'quvchilar if-qismga will qo'yadilar - if-qismda Present Simple ishlatiladi.)
• Noto'g'ri: If I would be rich, I would open an animal shelter. -> To'g'ri: If I were rich, I would open an animal shelter. (Would faqat asosiy qismda keladi, if-qismda emas.)
• Noto'g'ri: If I was you, I would join the eco-club. -> To'g'ri (rasmiy): If I were you, I would join the eco-club. (Second Conditional da barcha shaxslar bilan were afzal.)
• Noto'g'ri: If we had protected the forest, many birds would have survive. -> To'g'ri: If we had protected the forest, many birds would have survived. (Would have dan keyin fe'lning V3 shakli keladi.)
• Noto'g'ri: Unless we don't stop pollution, fish will die. -> To'g'ri: Unless we stop pollution, fish will die. (Unless allaqachon inkor - qo'shimcha not ortiqcha.)
• Noto'g'ri: If she knew about the problem, she will help. -> To'g'ri: If she knew about the problem, she would help. (Ikki qism bir turga mos bo'lishi kerak: Past Simple + would, will emas.)
• Noto'g'ri: If the climate would change slower, animals could adapt. -> To'g'ri: If the climate changed slower, animals could adapt. (If-qismda would emas, Past Simple.)
• Noto'g'ri: When I were a scientist, I would study leopards. -> To'g'ri: If I were a scientist, I would study leopards. (Xayoliy shart uchun if kerak; when real vaqtni bildiradi.)

8-bo'lim. Problem-solving discussions - muammo yechish munozaralari

Quyidagi munozara topshiriqlari guruh ishlashi uchun mo'ljallangan. Har bir muammoda o'quvchilar shart gaplaridan foydalanib yechim taklif qiladilar.

Munozara 1. The Snow Leopard Problem (First Conditional)

Vaziyat: O'zbekiston tog'larida 100 dan kam qor qoploni qolgan. Brakonerlik va yaylovlarning kengayishi asosiy xavf. Guruhda muhokama qiling:

1. What will happen if we do nothing? - If we do nothing, the snow leopard will disappear from Uzbekistan within twenty years.
2. If the government pays farmers for lost sheep, will they stop hunting leopards?
3. If schools teach children about this animal, how will attitudes change?

Munozara 2. If You Were the Minister... (Second Conditional)

Har bir o'quvchi Ekologiya vaziri rolini oladi va uchta qaror e'lon qiladi:

• If I were the Minister of Ecology, I would double the size of national parks.
• If I had an unlimited budget, I would build wildlife crossings over every motorway.
• Guruh har bir taklifni baholaydi: What would happen if we did this? Who would support it, and who would be against it?

Munozara 3. Learning from the Past (Third Conditional)

Orol dengizi tarixini o'rganing va o'tmishdagi xatolarni tahlil qiling:

1. If engineers had planned irrigation differently in the 1960s, what would have happened to the sea?
2. If local people had been consulted, would they have agreed to the plan?
3. Xulosa chiqaring: What lessons can we learn so that we don't repeat these mistakes? (bu yerda First Conditional ga qaytiladi: If we learn from history, we won't repeat it.)

Munozara 4. Chain game: Conditional chains

Zanjir o'yini: birinchi o'quvchi First Conditional bilan jumla boshlaydi, keyingisi oldingi natijani yangi shartga aylantiradi:

• A: If we cut down the forest, birds will lose their nests.
• B: If birds lose their nests, insect numbers will grow.
• C: If insect numbers grow, farmers will use more chemicals...

O'yin ekotizimdagi zanjirli bog'liqlikni ham, grammatikani ham mustahkamlaydi.

Metodik maslahat: Munozaralarda o'quvchilardan javobning GRAMMATIK turini oldindan belgilashni so'rang: real taklif - First Conditional, xayoliy g'oya - Second, o'tmish tahlili - Third. Shunda ular "qaysi zamon" degan savolni "qanchalik real" degan savolga bog'lashni o'rganadilar - bu B2 darajaning asosiy ko'nikmasi.

Qiziqarli faktlar (Did you know?)

• Qor qoploni (snow leopard) O'zbekistonning G'arbiy Tyan-Shan tog'larida yashaydi va Qizil kitobga kiritilgan. Agar himoya dasturlari muvaffaqiyatli bo'lsa, ularning soni asta-sekin tiklanadi - If conservation succeeds, the population will slowly recover.
• Buxoro bug'usi (Bukhara deer) 20-asr o'rtalarida deyarli yo'qolib ketgan edi. Zarafshon qo'riqxonasi tashkil etilmaganida, bu tur bugun mavjud bo'lmasdi - klassik Mixed Conditional misoli.
• Saygak (saiga antelope) burnining g'aroyib shakli havoni filtrlaydi: If a saiga runs across dusty steppe, its nose cleans the air it breathes - Zero Conditional harakatdagi tabiat qonuni.
• Xalqaro tabiatni muhofaza qilish ittifoqi (IUCN) ma'lumotlariga ko'ra, agar hozirgi tendensiya davom etsa, kelgusi o'n yilliklarda minglab turlar xavf ostida qoladi - ekologlar aynan First Conditional tilida ogohlantiradilar.
