林冲忍无可忍,奋起反抗,杀死了差拨、富安、陆谦,投奔梁山。对林冲投奔途中的情形,前人曾吟唱道:

登高欲穷千里目,愁云低锁衡阳路。

鱼书不至雁无凭,几番空作悲愁赋。

回首西山月又斜,天涯孤客真难渡。

丈夫有泪不轻弹,只因未到伤心处。

请认真阅读这首唱词,然后将“回首西山月又斜,天涯孤客真难渡”扩写为一段文字。

要求:①以林冲为描写对象,通过景物描写衬托人物心理;②想象合理,与林冲当时的心理相吻合;③不少于200字。

There are many American expressions about insects--- like bees, for example. Bees are known as very hard workers. They appear to be busy, moving around their homes, or hives (蜂窝). So you might say you were as busy as a bee if you spent your weekend cleaning your house. In fact, you might say your house was a beehive of activity if your whole family was helping you clean. You also might say you made a beeline for something if you went there right away. When we go to see a movie, my friend always makes a beeline for the place where they sell popcorn (爆米花) .

Here is an expression about bees that is not used much any more, but we like it anyway. We think it was first used in the 1920s. If something was the best of its kind, you might say it was the bee’s knees. Now, we admit that we do not know how this expression developed. In fact, we do not even know if bees have knees!

If your friend cannot stop talking about something because she thinks it is important, you might say she has a bee in her bonnet (女帽). If  someone asks you a personal question, you might say “that is none of your beeswax”. This means none of your business.

Speaking of personal questions, there is an expression when their children ask, “Where do babies come from?” Parents who discuss sex and reproduction (生殖) say this is talking about the birds and bees.

Butterflies are beautiful insects, but you would not want to have butterflies in your stomach. That means to be nervous about having to do something, like speaking in front of a crowd. You would also not want to have ants in your trousers. That is, to be unable to sit still.
