There's nothing more exciting to see with your glasses on, while you look nice. You can take those off if you wish to, or you can try to just be splitting the light in the room until the TAs grab your glasses, either is fine.

虽然你们戴着眼镜很好看，但现没什么东西需要戴着看了，你们可以拿掉了,或者你们在助教收上来之前，试试看分开屋里的光。

Can anyone not see it? Does anyone need -- actually I can't even tell if you raise your hand. So ask your neighbor if you can't see it and get one of the plates if you're having trouble seeing with the glasses. So this should match up with the spectrum that we saw.

有人没看到的吗？,有人需要-实际上你们举手我也看不见,看不到的话就问你们周围的人借个小片,如果你们用眼镜看不到的话,这应该和我们看到的光谱是吻合的。
