橘子关于名字橘子是日常生活中最常见的水果之一。
然而在水果市场上觅食的时候，却意外地发现，同一种水果，有的卖家标的是“橘子”，而有的卖家标的是“桔子”。
究竟是“橘子”还是“桔子”呢？“桔”，它的正音应该是“jié”，通常用在“桔梗”这个词里，就是《桔梗谣》里的桔梗，也就是朝鲜小菜里的桔梗。
“桔”被借用“橘”之义，是从广东开始的。
在广东话中“橘”同“桔”“吉”发音很相近，至今南方很多地方仍保留着相互赠送大桔的风俗，谐音“大吉”，可能最初就是出于吉祥祝福的心愿，人们故意将“橘”写成“桔”。
除此之外，由于“桔”字易写易识，拥有广泛的群众基础。
冰心1975年发表的《小桔灯》用的就是“桔”。
1960年，中国农业科学院柑橘研究所成立，也是用“桔”代替“橘”命名。
这些用法都表明，“桔”字不再是“橘”的附属，已经登上了“大雅之堂”。
另外，简化字对推动全民文化素质提高和扫盲，发挥了不可估量的作用，书写简单了许多，便于扫盲，但是到了后期，简化字一度进入了“越简单越好”的误区。
比如在1977年提出的《第二次汉字简化方案》中，鸡蛋写成了“鸡旦”，停车写成了“仃车”，“橘子”的“橘”，被写成了“桔梗”的“桔”。
这给辨识带来了很多困难，于是这个方案未获通过。
但还是有很多字儿在民间流行，所以“橘子”变成了“桔子”。
1986年，《二简（草案）》被废除，但人们用“桔”来表示“橘”的热情依然没有减退。
而目前“橘”才是正确的写法。
关于药用价值橘子可以说全身是宝，其皮、核、络、叶都是“地道药材”，具有润肺、止咳、化痰和止渴的功效。
橘子皮可以美容，《本草纲目》中说陈皮（橘皮）“同补药则补；同泻药则泻；同升药则升；同降药则降”。
可见在古代，人们就已经认识到橘子的药用价值了。
橘皮入药称为“陈皮”，具有理气燥湿、化痰止咳、健脾和胃的功效，常用于防治胸胁胀痛、疝气、乳胀、乳房结块、胃痛、食积、输气等症。
其果核叫“橘核”，有散结、止痛的功效。
橘络，即橘瓤上的网状筋络，有通络化痰、顺气活血之功效，常用于治疗痰滞咳嗽等症。
橘肉味甘酸性温，具开胃理气、止咳润肺、解酒醒神之功效，主治呕逆食少、口干舌燥、肺热咳嗽、饮酒过度等病症，还可辅助治疗高脂血症、动脉硬化及多种心血管疾病。
关于注意事项①吃橘子时，不要将橘瓤外白色的筋络扯得一干二净。
因为________________________________。
②忌鲜橘皮沏茶饮。
摘下后的橘子大多用保鲜剂浸泡后再上市，保鲜剂为一种化学制剂，浸泡过的橘子对果肉没有影响，但橘子皮上残留的保鲜剂却难以用净水洗掉，若用这样的橘子皮泡水代替茶饮，对身体健康的损害是显而易见的。
另外，鲜橘皮含挥发油较多，由于挥发油气味强烈，会刺激肠胃，有损健康。
③吃橘子过多会引起结石。
橘子含水量高、营养丰富，含大量维生素 C、枸橼酸及葡萄糖等十余种营养物质。
食用得当，能补益肌体，特别对患有慢性肝炎和高血压患者，多吃蜜橘可以提高肝脏解毒作用，加速胆固醇转化，防止动脉硬化。
适当食用可增进食欲，但如食用不当反而无益。
④吃橘子过多导致上火。
橘子性温，多吃易上火，会出现口舌生疮、口干舌燥、咽喉干痛、大便秘结等症状。
儿童尤其不宜多吃橘子。
橘子富含胡萝卜素，若大量吃入，每天500克左右连吃两个月，可出现高胡萝卜素血症，表现为手、足掌皮肤黄染，渐染全身，可伴有恶心、呕吐、食欲不振、全身乏力等症状，有时易与肝炎混淆。
有些孩子吃橘子过多还会出现中医所说的“上火”表现，如舌炎、牙周炎、咽喉炎等。
停吃一两周，基本可以恢复健康。

9. （5分）阅读下面文字，回答问题。
送别童庆炳①母亲怎么也没有想到，十九岁的我，要离开家乡到北京读书。
她事先完全没有准备，一切都来得太突然。
不但在她的想象中，而且在我的想象中，北京简直就像天边一样遥远。
②1955年，福建还不通火车。
从我家乡连城县出发，要坐五天的长途汽车，才能到达有火车的江西鹰潭。
山高路险，行程艰难。
“宁化、清流、归化，路隘林深苔滑”，毛泽东的词句所描写的路，正是我去北京的必经之途。
那时候，我们那里的人去一趟北京，感觉上比我们现在去一趟西欧、北美还要遥远得多。
③记得我在龙岩读中等师范学校时，有一位老师长途跋涉去北京开了一次会，就像出了一次国似的，回来后在全校做了个报告，专门讲在北京的见闻。
至今我还记得，他津津有味地讲北京冬天街道两旁的树干，都涂了像人一样高的白灰，远远望去，像一排排穿着白衣的护士整齐地站着。
④我去北京读书的消息，经乡亲们渲染，变得“十分重大”。
祖母和母亲手足无措，心神不宁，不知该为我准备什么好，更有一种生离死别之感盘桓在她们心间，折磨她们。
可理智上她们又觉得儿孙“进京”读书是光宗耀祖的事情，是不能轻易哭的，离别的痛苦只能忍着。
所以我离开家时，祖母始终是平静的，起码表面上如此。
⑤我出发那天，母亲要送我到离我们村子十五里的朋口镇去搭汽车。
她着意打扮了一番，穿一身新的士林蓝布衫，脸上搽了白粉，嘴唇也好像用红纸染过，脑后圆圆的发髻上还一左一右插了两朵鲜红的花，让人觉得喜气洋洋。
那十五里路我们是如何走过来的，在我的记忆中已很模糊了。
唯有在汽车开动前，母亲“空前绝后”的哭和止不住的眼泪，至今仍历历在目。
⑥她拉住我的手，语无伦次地说：“北京‘寒人’（冷），要多着衫。

When they see seabirds fly high，they say it will be a nice day. When the weather is bad，the seabirds stay on the shore(岸)．They don't like to fly in strong winds and they sit in trees when rain is on the way.Other people look at different animals on the farm. For example，chickens may make a lot of noise and run here and there when rain is on the way. Frogs(青蛙)can tell the weather，too. When rain is on the way，they stay in water and make a lot of noise too. But when it is a nice day，they will be quiet and jump out of the water.26．When some people see seabirds ________they think it is going to be a nice day.A．sit in treesB．stay on the shoreC．fly highD．fly to the trees27．Chickens ________ when rain is on the way.A．run around B．keep quiet C．know nothing D．sit in trees28．When rain is on the way，frogs may ________.A．eat a lotB．not make a lot of noiseC．go to the landD．not jump out of the water29．________ will make a lot of noise if it rains.A．Frogs and seabirdsB．Chickens and seabirdsC．Frogs and chickensD．Chickens and cats30．The passage wants to tell us that ________.A．only animals can tell the weatherB．we can know the weather from some animalsC．all animals like rainD．all animals can tell the weatherBSome people don't like storms，but I think they are very exciting.There are often storms at the end of a hot summer day. The clouds are small and white at first. However，they get bigger and bigger until they make one large，black cloud. The sky gets dark and it starts to rain hard. And then the streets are like swimming pools. There is a flash of bright light in the sky and then，after a few seconds，you can hear the loud “bang” of thunder.Light travels very fast，so we always see the lightning before we hear the thunder. If the clouds are one kilometre away，you can count to three，between the lightning and the thunder.Lightning is very beautiful but it can also be dan-gerous. Lightning is electricity(电流) “jumping” to the ground from a cloud. It usually hits ta ll things，so if you are outside when there is thunder and lightning，don't stand under a tree.31．We can see ________ in a storm.A．a light rain B．a white cloudC．a small cloud D．lightning32．The streets are like swimming pools because________.A．the cloud is large and darkB．the sky gets darkC．it rains hardD．it's a hotter summer day33．What does the underlined word “flash” mean?A．闪光B．明亮C．响亮D．阳光34．If the clouds are three kilometres away，you can count to ________ between the lightning and the thunder.A．three B．six C．nine D．twelve35．What should you do when there is thunder and lightning?A．Climb up a tree. B．Stand under a tree.C．Stand under tall things. D．Stay in a car.CWhen the weather is hot, you go to a lake or an ocean. When you are near a lake or an ocean，you feel cool. Why？The sun makes the earth hot but it cannot make the water very hot. Although the air over the earth becomes hot，the air over the water stays cool. The hot air over the earth goes up. Then the cool air over the water moves in and takes the place of the hot air.When it moves in，you will feel the wind. And the wind makes you cool.Of course，scientists cannot answer all of our questions. If we ask “Why is the ocean full of salt？”，scientists will say that the salt comes from rocks. When a rock gets very hot or very cold，it cracks(断裂)．Rain falls into the cracks and then carries the salt into the ocean. But then we ask，“What happens to the salt in the ocean？”The ocean does not get saltier every year. Scientists are not sure about the answer to this question.We know a lot about our world. But there are still many answers which we don't have and are curious(好奇的) about.36．The main idea of this passage is that ________.A．people feel cool when they are near a lake or an oceanB．scientists can explain many things，but not everythingC．scientists can explain everything about the oceanD．the salt in the ocean comes from rocks37．Now scientists know ________.A．what makes people feel cool near a lake or an ocean in summerB．everything about the oceanC．what happens to the salt in the oceanD．why the ocean does not get saltier and saltier38．A rock cracks when ________.A．rain falls B．it gets very hotC．it gets very cold D．Both B and C39．In the first paragraph，the underlined word “it” refers to ________.A．the hot air over the waterB．the cool air over the earthC．the hot air over the earthD．the cool air over the water40．Which of the following is NOT mentioned in this passage?A．The reason why people feel cool when they are near a lake or an ocean in hot weather.B．The reason why the ocean doesn't get saltier every year.C．The reason why the water in the ocean is salty.D．The reason why rocks crack.四、任务型阅读(每小题2分，共10分)Here is some information about Sanya，Harbin and Beijing.Sanya is in Hainan Province.
