Hello, everyone. My name is John. I'm the teaching assistant for this lab session.
大家好。我叫約翰。我是這次實驗課的助教。
Let me explain a little about it. As you may know already, it's a required meeting once a week.
讓我講一下這課。你們可能已經知道,這是每周要上一次的課。
I expect you to do all the experiments and keep the results in your lab notebook.
我希望你去做所有的實驗并在你的實驗筆記本中記錄結果。
I'll collect the notebooks every two weeks.
我將每隔兩周收一次筆記本。
You'll be graded on lab notebooks and quizzes.
我將根據你的實驗筆記本和小測驗進行評分。
But the most important information I want to give you now is about safety.
但是我想給你們傳達的最重要的信息是有關安全的。
First of all, you must wear shoes that cover your feet in the lab. Tennis shoes are OK.
首先,你們在實驗室里必須要穿上遮住腳的鞋。可以穿網球鞋。
Also, don't wear loose clothes, long scarves, big necklaces, or loose belts — they get caught in something or fall into liquid.
此外,不要穿寬大的衣服、戴長圍巾、大項鏈或系寬松的腰帶——它們很容易卡到某個東西里面或掉進液體里。
Another thing to do for safety is cleaning up.
另一件確保安全的事情是清潔。
Be sure to put the waste in the correct containers.
務必把廢棄物放進正確的容器內。
We can't mix liquid with paper. This is extremely important. I don't want any fires in this room.
我們不能將液體和紙混到一塊。這一點極其重要。我可不想這間教室著火。
You are responsible for washing out your own lab equipment and putting it away.
你要負責清洗你自己的試驗設備并把它收起來。
If you don't do this, I will take away points from your grade.
如果你不這樣做的話,我會從你的分數中扣分的。
Nobody's going to clean up after you. OK, any questions?
沒有人會幫你清理干凈的。好了,還有什么問題嗎?
