If we split up, I will be afraid to go out, Because no matter where, Have our memories, Everywhere I go I carry my乱逛of holding you, Looked at me with tears and I will be sad with you, Accompanied me crazy happy I accompany you, To say I am sorry I love you and you hesitate to half-day, Me into the future and your hard efforts to this end you Students will meet every time I think of the band you I am afraid to go to school afraid to go home two first-line of you, Almost all the money is spent on me for you, Because I have prepared a surprise for their happy and half-day to you, Even if there is a lot of baggage would not let you carry one, Crowded subway, holding my hand tightly for you, In the cold wind or rain, the rover will be waiting for me or you, Have taken the trouble to accompany me shopping for my clothes you choose to make any suggestions, Winter and summer vacations every year with me once you travel, Chaos because I play,乱吃things you get into the act, Every time I have been engaged in the collapse were still forgive me every time I come to see me inclusive of you.
如果我们分手了,我一定会害怕出门,因为无论到哪里,都有我们的回忆,背着我牵着我到处乱逛的你,看着我流泪会陪我一起伤心的你,陪着我发疯陪着我快乐的你,为了说一句我爱你而不好意思犹豫半天的你,把我纳入你的将来并为此拼命努力的你,每一次同学聚会都会想到把我带上的你,害怕我担心上学回家两点一线的你,几乎把所有的零花钱都花在我身上的你,因为给我准备了惊喜而自己开心半天的你,即使有一大堆行李也不肯让拎一件的你,拥挤的地铁里紧紧牵着我的手的你,在凛冽的寒风又或者飘泊的雨中还是会等我的你,陪我逛街不厌其烦地为我出主意选衣服的你,每年寒暑假陪我出去旅游一次的你,因为我乱玩,乱吃东西,胡作非为而大发雷霆的你,每一次都被我搞的崩溃却依旧每一次都原谅我包容我来找我的你。

Once again, is the pattern design: here refers to products that are, such as the content of the scenery, characters, animal, pattern in full embroidery embroidery cloth embroidered: full and half finished half embroidery embroidery than the finished product or process from visual complexity, are good with embroidered products embroider becomes time-consuming and long, so in the same specification under the full price to embroider, like the Great Wall painting scroll all belong to the high-quality goods.
再次是图案:这里说的图案是指成品的内容,如有风景的,有人物的,有动物的等,图案在绣布上分满绣和半绣:满绣的成品比半绣的成品无论从视觉上还是工艺复杂程度上都好,满绣的成品绣成耗时也长,所以在同等规格下满绣的价格要高,象长城清明上河图都属于精品中的精品。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
