It was fun to do, and our whole team thought it was funny.M: Well, great job.L: I think it's the best work your team has ever done.What may need to be delayed?-Some of their other projects What does the schedule depend on?-It depends on how important the project is.They are putting a lot of pressure on us now,especially since they read your proposal.Can't you delay some of our other projects?It's a very creative way of presenting their company.She submitted her proposal a week ago.They want you to get started on it as soon as possible.I think it's the best work your team has ever done.L4-U2-P4-6 Dialogue : A Video Project 2M: When can you get started on the project?L: Are they going to pay extra? In my proposal, I said the earliest start date would be one month after signing the contract.M: Was that in the proposal?L: Yes, it was. Have they signed the contract yet?M: No, they haven't, but I'm sure they will right away.The proposal said that the earlieststart date would be one month after signing the contract.L: They'll also need to make an advance payment. That was in the proposal, too. We can't stop everything else just because they are excited.M: OK, I'll get back to them and let them know.L: Yes, please do, I've been through this kind of thing before.To get back to them means to contact them.Are they going to pay extra?I've been through this kind of thing before.They'll also need to make an advanced payment.We can't stop everything else just because they are excited.They want to get started earlier than what was in the proposal.。

Level3.Unit2 Part1作者：Ding MingListening: States of Matter物质状态Matter is made of atoms and molecules.Water, for example, is the H2O molecule.This means that a molecule of water has 3 atoms.这意味着水分子有3个原子。

A water molecule has two hydrogen atoms and one oxygen atom.Substances like sugar have many atoms in their molecules.A molecule of sugar has many atoms, including carbon, hydrogen and oxygen.------------------------------------------------------------------------------------------------------Matter is made of molecules, such as H2O, which is the water molecule.Matter can be one of three states, solid, liquid or gas.Water and ice are the same substance, but they are in different states.These states depend on the temperature of the molecules.When we heat a substance, the molecules move faster and try to take up more space. When we cool a substance, the molecules move more slowly.When we cool a substance to its freezing point, it becomes a solid.-------------------------------------------------------------------------------------------------------------In a solid, the molecules move very little.Their positions are almost fixed.To be fixed means that their positions don’t change.If we heat the molecules, they move faster and away from each other.The solid begins to melt, like ice cream on a hot day.-----------------------------------------------------------------------------------------------------------At a certain temperature, a solid begins to change into a liquid.The temperature at which a solid change into a liquid depends on the substance.For water, the solid begins to change into a liquid when its temperature rises to about 0 degree Celsius.For some substances, such as steel, the temperature at which it becomes a liquid is much higher.对于某些物质,如钢,它变成液体的温度要高得多。
