Para 2
The trouble most of us have with glue can't be blamed on the glue-makers. It isn't their fault. We just ask too much of glue and, of course, they encourage us to overestimate what it will do by showing us pictures of a drop of it lifting an elephant. I can't get a dish to hold together, and they're lifting elephants with it. Ed White, the football player, can't pull apart two blocks stuck with it.
我们大多数人在用胶时所遇到的问题不能归咎于制胶商。这并不是他们的错。我们只是对胶要求过多罢了，无可否认，他们所展示的几张用一滴胶提起一头大象的图片，使我们过高地估计了胶的性能。用这种胶，我连一个盘子都粘不起来，他们却可以提起大象，连足球队员艾德\怀德都掰不开用这种胶粘起来的两片木块。 ? The trouble most of us have with glue can't be blamed on the gluemakers. blame on:

Para 3
Para 3 It's interesting how often sticking things together and making them stay that way comes up in our lives. In my lifetime, I've had a lot to do with glue and the experiences have almost always been disappointing. I was disillusioned by glue early in life. One of the other kids in first grade told me his mother said you could make things stick together with a paste made of flour and water. Mixing flour and water never worked for me as a kid. 非常有趣的是，我们用胶把东西粘起来在生活中是常有的事。我一生中曾用胶粘过许多东西，但大多数经历总是令人失望。胶早就破灭了我的幻想。一个一年级的小孩告诉我，他妈妈说用面粉和水调成浆糊可以粘东西。对我而言，在孩童时代，面粉和水混合在一块根本就没用。

Maybe I just have no knack for glue. It's hard to remember a time in my life when the local hardware store wasn't pushing some new miracle bond, but none of them has ever proved to be miraculous for me. 也许我没有掌握用胶的诀窍。我这一辈子只记得当地五金店推行过新型奇效粘合剂这一件事。但在我看来，没有哪种胶真正有过奇效。 1.

Book 3 Unit 4 Glue
[paraphrase] I hardly remember that I had a knack for glue in my life before the local hardware store sold some new miracle bond. But my own experiences with glue were disappointing, because glue didn't prove to be miraculous for me.

Maybe that's why half the stuff I glue together comes apart.
这则空军消息说，他们将物品的两面粘起后，置之于\一个250摄氏度、烤箱般的压力锅中一小时之久\。嗨，我只是碰巧没有用来加热的压力锅。也许这就是我粘的一半材料有分开的原因。

It happened that she was out when he called. She happened to be out. 翻译段落 Para 6 Around the office I use paper cement. It's fun to play with and it works if it's the right consistency. The problem is, I only use it once a month or so, and it keeps getting too thick in the jar. We have a one-gallon can of paper cement thinner, and over the period of a year I use more thinner than I use cement.
在办公室周围，我用水泥粘纸。这东西很好玩，而且粘稠度适宜则有效。问题是，我仅在大约一月左右用一次，在坛子里还是那么稠。我们有一个一加仑罐子装满了水泥稀释液，在这一年中，我用的稀释液比水泥还要多。

2. We have a one-gallon can of paper cement thinner, and over the period of a year I use more thinner than I use cement.
[paraphrase] Around the office, the writer uses paper cement to hold things together. His problem is that paper cement keeps getting too thick after a period of time, and when it is not the right consistency, it does not work. So he has to use a lot of thinner to dilute it. As a result, he uses more thinner than cement.
