小学三年级应用题，急．

规定各个数是整十数就是迷惑你，
实际这道题就是考察乘法口诀是否掌握的熟练。
即：
1、几乘以3得十几？3x4=12，3x5=15，3x6=18。只有5符合。
2、几乘以6得二十几？只有4x6=24，4符合。
3、几乘以6得三十几？5x6=30，6x6=36。只有6符合。
4、几乘以6得四十几？6x7=42，6x8=48。只有8符合。
所有的数后加零，即是整十数。
让孩子自己认真想想就有答案了。

关于生命的周记（1000字）求答哦！急！

生命的奇迹
树，砍断了枝条还能再生；草，烧了还能在长。悬崖上的一棵松树茁壮地成长着，不需要谁来施肥，也不需要谁来灌溉。一粒种子，可以掀翻压着它的石块，顽强地向上生长……许多平凡的事物常常能创造出是生命的奇迹。
在星期天的下午，我做完了作业，闲来无事，便来到楼下散步，却在无意之中见到了令我震惊的一幕。
走着走着，我发现了一个蚂蚁窝。蚂蚁们正在自己的岗位上井然有序地“工作”着：有的正在搬一块“庞然大物”——面包渣，只见它们使出吃奶的劲儿，拼了命地往窝里拉，想把它拖进去好好的美餐一顿；有的在觅食，它们东看看，西瞧瞧，认真地寻找着食物；有的在交谈，它们用自己触角碰对方的大牙，仿佛在说：“那边有东西，快去搬吧！”……..
看着看着，我情不自禁地想给它们捣捣乱，跟它们开开玩笑。我用杯子灌了一大杯水，捉了大约十几只蚂蚁，放在一个对它来说“深不见底”的塑料盒子里，然后猛然向里面倒水。蚂蚁们一见突如其来的洪水，一个个惊慌失措地四处逃蹿，但是水还是“刷——”地一下无情地没过了它们的头顶。它们用尽全身力气，挥舞着六足，妄想着游去出。虽然爬出去的希望十分渺渺茫，可是蚂蚁们并没有放弃，它们还在坚持，想要爬出去求生。
也许是它们的勇气和坚持不懈地精神感动了老天爷，一只离盒子边缘较近的蚂蚁竟然游到了边缘上！一些在水中心的蚂蚁只能对天祈祷和用“狗爬式”拼命游泳。看着它们在水中苦苦挣扎但无济于事的样子，我不忍心了，拿了一根树枝去帮助他们。蚂蚁一见到树枝这根救命稻草，顿时眼睛发亮，不用教，也知道要死死地抱住树枝，它们一抱住树枝，我就把它们“解救”了上来。
小小的蚂蚁明知道自己落到了水里，活下来的几率已经小得可怜了，可它们竟然为了挽救生命再次鼓起勇气向前游。连像蚂蚁这种地位卑微的低等生物也知道要珍惜生命，更何况我们人呢？法国的米歇潘曾经说过这样一句话；生命是一条艰险的狭谷，只有勇敢的人才能通过。就是这个道理。看来，生命的真正意味就是——勇气！只要有了勇气，无论什么艰难险阻都能克服

主题保护环境的作文急！

不知道这个行不行
古往今来，地球妈妈用甘甜的乳汁哺育了无数代子孙。原来的她被小辈们装饰得楚楚动人。可是，现在人类为了自身的利益，将她折磨得天昏地暗。人类只有一个地球；而地球正面临着严峻的环境危机。“救救地球”已成为世界各国人民最强烈的呼声。
我为周围环境的恶化而感到心痛，我想：作为未来接班人的青少年，如果不了解环境问题的严重性，无视有关环境保护的法律法规，不去增强环境保护意识，我们的生命将毁在自己的手中，老天将对我们作出严厉的惩罚。为此我下定决心要从我做起爱护环境，保护我们这个赖以生存的家园，做一个保护环境的卫士。
在刚过去的一年中，我积极参加学校开展的植树活动，带领我们六（2）中队的班干部创立了“绿色天使”植绿护绿小组，鼓励队员们在校园里认养了一棵小树苗，利用课余时间给它梳妆打扮，为它长成参天大树打下了基础。在学校组织的“让地球充满生机”的签字活动中，我郑重地在上面签下自己的名字，并写下了自己对环保的决心和期望，对美好未来的憧憬。我积极参加学校在世界环境日举行的有奖征稿，认真查阅、收集各类资料，进行社会调查，撰写有关环境治理设想方面的文章，我经常去参加学校组织的环保讲座，观看环保方面的录相带，积极参预环保知识问答调查活动，认真填写每一项提问。我参与了“红领巾植绿护绿队”的网站建设，在上面发布大量的环保图片和环保知识，以及关于环保的各方面的法律知识，我国在环保方面发展动向、世界各国的环境保护情况；每个月我都利用网络、报纸，查找一些最新的不同的专题和板块“环保资讯”来告诉大家；还定期制作一些宣传板来宣传环保知识和生活中的环保常识。提高了大家的环保意识；号召同学们从不同的方面来关爱自己的家园，从身边的小事做起，为周围的环境奉献自己的一份力量!我积极动员身边的人一起来依法保护和建设人类共有的同样也是仅有的家园，为促进经济和社会的可持续发展，为人类的文明做出贡献。我还和同学们共同发起“养一盆花，认养一棵树、爱惜每一片绿地，让我们周围充满绿色”和“小用塑料袋不使用泡沫饭盒和一次性筷子，让我们远离白色污染”的倡议。让我们放下方便袋，拿起菜篮子，让我们共同走向美好的绿色的明天，走向辉煌、灿烂的未来!
据我收集到的一份报告说：“环境问题是由于人类不合理地开发和利用自然源所造成的。触目惊心的环境问题主要有大气污染、水质污染、噪声污染、食品污染、不适当开发利用自然资源这五大类。”一个个铁一样的事实告诉我们，它们像恶魔般无情地吞噬着人类的生命。它威胁着生态平衡，危害着人体健康，制约着经济和社会的可持续发展，它让人类陷入了困境。为此我作出宣告：“只要我们——人类有时刻不忘保护环境的意识，有依法治理环境的意识，地球村将成为美好的乐园”。未来的天空一定是碧蓝的，水是清澈的，绿树成荫鲜花遍地，人类可以尽情享受大自然赋予我们的幸福。
“真正检验我们对环境的贡献不是言辞，而是行动。”虽然我现在做得只不过是一些微小的事，但是我坚信要是我们人人都有保护环境的责任心，从自己做起，从小事做起，携手保护我们的家园，自然会给人类应有的回报。在温暖的摇篮——草原上小憩；在慈祥的笑脸——天空下成长，在爱的源泉——河流中沐浴

求助关于英语的问题急！

iǎozi 饺子 or 饺子 is a Chinese dumpling widely spread to Japan, Eastern and Western Asia.
Jiaozi typically consist of a ground meat and/or vegetable filling wrapped into a thinly rolled piece of dough, which is then sealed by pressing the edges together or by crimping. Jiaozi should not be confused with wonton: jiaozi have a thicker, chewier skin and a flatter, more oblate, double-saucer like shape (similar in shape to ravioli), and are usually eaten with a soy-vinegar dipping sauce (and/or hot chili sauce); while wontons have thinner skin, are sphere-shaped, and are usually served in broth. The dough for the jiaozi and wonton wrapper also consist of different ingredients.
Dumplings that use egg rather than dough to wrap the filling are called "egg dumplings" or (蛋饺; pinyin: dànjiǎo).
Common dumpling meat fillings include pork, mutton, beef, chicken, fish, and shrimp which are usually mixed with chopped vegetables. Popular vegetable fillings include cabbage, scallion (spring onions), leek, and Garlic chives. Dumplings are eaten with a soy sauce-based dipping sauce that may include vinegar, garlic, ginger, rice wine, hot sauce, and sesame oil.
Dumplings Jiaozi are one of the major foods eaten during the Chinese New Year, and year round in the northern provinces. They look like the golden ingots yuan bao used during the Ming Dynasty for money and the name sound like the word for the earliest paper money, so serving them brings the promise of wealth, good luck and prosperity. Many families eat these at midnight on Chinese New Year\'s Eve so they have money at the changing of the years. Some cooks will even hide a clean coin in one for the most lucky to find.
Jiaozi are eaten all year round and can be eaten at any time of the day – breakfast, lunch or dinner. They can constitute one course, starter or side dish, or the main meal. Every family has its own preferred method of making them, with favourite fillings, and of course, jiaozi types and preparation vary widely aording to region.
A plate of fried dumplings (guotie), and dipping sauce.
Cantonese style Chinese dumplings (gaau) are standard fare in dim sum. Gaau is simply the Cantonese pronunciation for 饺 (pinyin: jiǎo). The immediate noted difference to jiǎozi is that they are smaller and wrapped in a thinner translucent skin, and usually steamed. In other words, these are steamed dumplings. The smaller size and the thinner pastry make the dumplings easier to cook through with steaming. Fillings include shrimp, scallop, chicken, tofu, mixed vegetables, and others. The most mon type are shrimp dumplings (har gow). In contrast to jiǎozi, gaau are rarely home-made. Similar to jiaozi, many types of fillings exist, and dim sum restaurants often feature their own house specials or innovations. Dim sum chefs and artists often use ingredients in new or creative ways, or draw inspiration from other Chinese culinary traditions, such as Chiuchow, Hakka, or Shanghai. More daring chefs may even incorporate a fusion from other cultures, such as Japanese (teriyaki) or Southeast Asian (satay, curry), while upscale restaurants may use expensive or exotic ingredients such as lobster, shark fin and bird\'s nest. Another Cantonese dumpling is the jau gok.
Jiaozi were so named because they were horn shaped. The Chinese for "horn" is jiǎo (角), and jiaozi was originally written with the Chinese character for "horn", but later it was replaced by a specific character 饺, which has the food radical on the left and the phoic ponent jiāo (交) on the right. [1]
Aording to folk tales, jiaozi were invented by Zhang Zhongjing, one of the greatest practitioners of traditional Chinese medicine in history. They were originally called "娇耳"(Pinyin: jiao\'er) because they were used to treat frostbitten ears.
