Hello there！
大家好！今天是我和大家趣聊英文的的第11天，the 11th day，很多朋友都在堅持閱讀學習，I’m sure you’re going to make it soon.你們英語的摩天大樓正在一磚一瓦中慢慢地矗立起來！I’m soooo proud of you！
最近有同學問我介詞到底是什麼？今天和大家說得清楚一點~ Let me make it clear.
介詞的英文是prepositions，縮寫為prep. 介詞一般用於名詞和代詞前，表示該詞與句子其他成分的關係，比如：Jerry is in the classroom. in這個介詞把Jerry和classroom聯繫了起來，說明了Jerry的位置。介詞後如果出現動詞，動詞要加ing，如果出現人稱代詞，要用賓格，這兩點每個同學必須要清清楚楚！舉例：Thank you for teaching us English. 感謝你教我們英語。 /Don’t worry about us.We’re studying hard now. 別擔心我們，我們正努力學呢。See？
介詞在句中一般不做任何成分，可以分成簡單代詞（in,on,at,about...）和介詞短語（in front of,because of...）等，也可以分成時間介詞、方位介詞等。
接下來，給大家總結一下我們之前學過的一些重要的介詞用法和搭配，好好感受一下介詞的靈活，不懂的一定要查資料或問我，A lazy man can never accomplish anything.懶惰的人將一事無成。我們都不想成為這樣的人，是不？

9. withplay with our friends/a man with an umbrella/help sb with sth/Who’s the boy with big eyes?
備註：in the day 意思是在白天；at work 在工作；a photo of my family也可以說成my family photo;hear from sb 意思是收到某人的來信；in the west 意思是在西方（國家）；look after 照顧，照看，take care of 也有此意，但後者意思要多很多；on the morning of May 1st,2008 這個on的用法考試中不能再錯了。
介詞還是很重要滴!所以希望大家認真學習！
2020真的很難，我們一起努力，沒有到不了的明天！大家加油！中國加油！Bye for now!
