Wait VS Await🕧🕐🕜 ✔️Await 1️⃣ AWAIT is way more formal. We normally don’t use it in everyday conversations. It is mainly used in formal letters and emails. For example, if you are expecting a reply from someone, you can use it at the end of your letter/email: I’m awaiting your reply. 2️⃣The verb AWAIT must be followed by an object. You can’t use it on its own. I’m awaiting two packages. 3️⃣The verb AWAIT can only be used with things. We can’t use it when we’re talking about people. I’m awaiting you. – Incorrect ❌ ➖➖➖➖➖➖➖➖➖➖➖➖➖➖ ✔️Wait 1️⃣WAIT must be used with a preposition (FOR or ON) I’m waiting for a bus. Wait on here till the bus comes. 2️⃣When we use WAIT we usually mention the length of time you that you have been waiting. I’ve been waiting for you for ages. 3️⃣We can use WAIT on its own. We have been waiting and waiting to show our store to you and the day is finally here! 4️⃣We can also use WAIT with another verb. Yesterday, I waited in a queue for 2 hours to withdraw money. 5️⃣We can use WAIT with both things and people. I am waiting for Lucy to call me back. While I was waiting for the bus, I read a magazine. TEZKOR VA SIFATLIK ONLAYN KURSLAR!

IELTS Listening: how to use practice tests It's a good idea to do practice tests (e.g. using the Cambridge IELTS books) in preparation for the listening exam. Here's some advice to help you benefit from doing practice tests: 1. Your score is not the most important thing The important thing is what you have learnt by doing the test. Were there any new words or phrases that you can learn? What did you find difficult? Did any of the questions trick you? In other words, what do you need to do to improve your score? 2. Check how accurate your answers are Be strict with yourself; every grammar or spelling mistake is important. For example, if the speaker says "The library has a collection of newspapers", you must not write "collection of newspaper". 3. Get into the habit of moving on If you missed something, forget about it and move on. Always prepare for the next question rather than worrying about a previous question. When you are given 30 seconds to check your answers, use the time to look at the next section instead. 📝Improve your English and prepare for tests, such as MULTILEVEL & IELTS reading, writing, speaking and listening with our online courses. ☎️ +998978317017 👨‍💻 @CEFR_IELTS_Andijan 🔔 https://t.me/MULTI_LEVEL_CEFR
