没办法。
再等等吧。我也在等着下载。

Silkworms make silk. Not(不确定，又像有that的音) much new. But did you know that these dusty little caterpillars can spin silk of different colors? White, yellow, pink, even green. Silkworms get the pigments that used to color the gus(谐音) of product from mulberry leaves, the only food they eat. They then use the silk to make themselves some seriously comfy cocoons. Some mutant silkworms can only make white cocoons. These monochromic characters have mutation in a gene called Y, which stands for yellow blood. They don’t absorb the yellow color carotenoid from mulberry leaves. So the blood’s color lessens and cocoons are white. This week scientists in Japan announced the Y gene produces protein that grabs onto carotenoids. This protein allows cells in the gut to extract the aloe pigment from mulberry leaves, and cells in the soglan(谐音) to take it up from the blood. By providing mutant silkworms with good copy of the Y gene, the scientists were able to restore the ability to make yellow cocoons. Such genetic manipulations might someday allow researchers to engineer silkworms to make crossing color silk. It was a little like(不确定，怎么听起来像lecture啊) tricking. May be they can get the worms to monogram your cell pidgins(谐音，做了一下午听力，到后来很难集中精力，听不出来了) well.

Now comes news of a couple of （more）molecules;
calm brain cell inside (感觉像insult)your head；
希望你问过老师的正确答案，谢谢

的确是more molecules
其他的都没问题。
谢谢Tina指正。^^

过来发泄一下。今天Mr. Butt没来，我请12年级英语老师帮我听的。印度人，说话口音那个重啊……我今天写一段描述，明明写的是senior student, 居然帮我读成了serious. 身为英语老师英语却不怎么样，这实在让人害怕啊。今天看到昨天作的assignment，给我打了好低的分。哭……大哭……哭死了。
她要是我10年级时候那个老师，给我打更低点我都没话讲。这个老师我不服啊~泪奔
我要背单词！我要背句式！我要练习写作文！一定要从这个眼高于顶的老师手上拿回个高分来！

good idea, support

小楣加油啊，严重支持你，呵呵，相信你的实力，一定可以征服阿三的啦

听了几天,虽然每次都听得很郁闷,但还是咬牙坚持下来了...感觉这几天还是有点进步....坚持....
过两天水平高点了我也把听抄发上来..

Silkworms make silk that much knew. But did you know that these dusty little caterpillars can spin silk of different colors? White, yellow, pink, even green. Silkworms get the pigments they used to color the custom product from mulberry leaves, the only food they eat. They then use the silk to make themselves some seriously comfy cocoons. Some mutant silkworms can only make white cocoons. These monochromic characters have mutation in a gene called Y, which stands for yellow blood. They don’t absorb the yellow color carotenoid from mulberry leaves. So the blood’s color lessens and cocoons are white.

红色部分是有疑问的。tricking 那个地方听着像是twi-king的音，不知道到底是什么？如果真的是tricking的话，这个音就很难听出来，哪位能帮忙解答下？谢谢！第一次发现这个帖子，第一次听，大家互相帮助，以后会坚持听得！支持lz!

小楣，不要难过，我们都支持你:handshake
印度人的英语实在是。。。。唉，别跟他计较

btw：你老师的名字很有意思，butt？？:loveliness:

xixihehe0167UID: 2253387

woodman进步很大啊，大家有目共睹，狂赞一下:loveliness:

xixihehe0167UID: 2253387

继续听抄:loveliness:


Silkworms make silk, that much you knew.But did you know these industrial little caterpillars can spin silk of different colors? White, yellow, pink, even green. Silkworms get the pigments that used to color the gossamer product from mulberry leaves, the only food they eat. They then use the silk to make themselves some seriously comfy (从woodman那里学来的，赞一个)cocoons. Some mutant silkworms can only make white cocoons. This monochromatic characters have mutation in a gene called Y, which stands for yellow blood. They don't absorb the yellow color carotenoid (从woodman那里学来的，再赞一个)from mulberry leaves, so their blood is colorless and their cocoons are white. This week scientists from Japan announced that the Y gene produces a protein that grabs onto carotenoids. This protein allows cells in the gut to extract the yellow pigment from mulberry leaves, and cells in the silk grant to(not sure) take it up from the blood. By providing mutant silkworms with a good copy of the Y gene, the scientists were able to restore the ability to make yellow cocoons. Such genetic manipulations might someday allow researchers to engineer silkworms that make custom-colored silk. Then with a little lecture tweaking(not quite sure), maybe they can get the worms to monogram your silk PJs(pajamas的简称) as well.
