What you look in at

An envious friend will want what you have, but will look at you as her inspiration or a role model, and compete with you to get in the lead.

一个羡慕你的朋友想要你所拥有的，但会把你作为对她的激励或是一个榜样，然后与你竞争来超越你。

You can look at the timeline charts in the back of your textbook to see when things were invented in different cultures at about the same time to see what I'm talking about.

你们可以看看教科书后面的时间表，看看不同文化背景下同一时间发明的东西，就知道我所说的了。

Because what you actually measure in the lab are changes in enthalpy, just like what you measure when you look at energy change of some sort, you measure the change in energy, right.

因为实际上你在实验室里，测得的是焓的改变，就像你在研究某种能量变化时，所测量的那样，你测量的是能量的改变，对吧。
