看东西模糊了,有重影。眼睛发红,有刺痛、瘙痒感。眼睛干燥,有酸涩感。注意力不集中、头晕、肩酸,甚至头痛、恶心、呕吐。
虚度年华 卑鄙庸俗
声色俱厉 皮肤松弛 凶神恶煞 心惊胆战 提心吊胆 狠之入骨
苦苦求衰 惊恐万状 目瞪口呆 鸦雀无声 溜之大吉 鸡毛蒜皮
倒背如流 清清楚楚 一清二楚 胡说八道 不由分说 瓮声瓮气
无精打采 来来回回 干干净净 仔仔细细 火舌飞舞 筋疲力尽
迫不得已 支支语语 兴致勃勃 咄咄逼人 自食其力 名正言顺
气急败坏 忧心仲仲 面色苍白 盛气凌人 无理取闹 乱七八糟
心满意足 疲惫不堪 恍然大悟 心宁不安 烟消云散 漫不经心
接连不断 大惊小怪 愤愤不平 愁眉苦脸 情不自禁 怒气冲冲
筋疲力尽 嬉皮笑脸 鸦雀无声 聚精会神 直截了当 心满意足
恼羞成怒 碌碌无为 永无止境 虚度年华 卑鄙庸俗 忧郁 威严
the sun rises in the east and sets in the west, which is caused by the rotation of the earth as you all know. but have you ever thought of the effect of the earths rotation on man and can you imagine what would happen if the earth stopped rotating?
the radius of the earth is about 6,370 kilometres. it takes the earth 24 hours to rotate once. objects on the earths equator move with the earth at a speed of 460 metres per second, and the air close to the earths surface turns at the same speed. if the earth stopped rotating suddenly, the air would keep flowing eastward at a speed of 460 metres per second. the wind would be fourteen times as powerful as a hurricane. at the same time sea water would rush eastward at a speed of several hundred metres per second, which might do damages much greater than a seaquake would do. obviously, men could hardly stand such a catastrophe.
even if such a catastrophe would not happen, there would be a great temperature difference on the two hemispheres of the earth, and the four seasons of the year would no longer occur because a day and a night would be as long as a whole year instead of 24 hours. all this would greatly affect the life of human beings, imals and plants and that would cause worse results than anything imaginable.
下面谈谈学习毅力的.问题。如果你有坚强的毅力,那么世界上就没有什么难事。学英语关键是能够持之以恒。
在学习过程中,你应该制订一个计划,一天记住几个单词,一天记住一两个句型。你不要小看“持之以恒”的力量。举个例子:
如果你一天背5个单词一年就是1825个单词,相当于初中三年再加高中一年零两个月的词汇量。如果你坚持两年你就能住3650个单词,相当于中学六年包括本科两年的词汇量。
在制订计划时要遵循以下几项原则:
1、计划要切实可行,不要好高务远。上面的例子已经说明,只要你能坚持天天学习,英语一定能学好。
2、要有坚强的毅力,每天都学习,不因为某些事而耽误了学习。如果哪天的工作没有完成,第二天一定要补上。连续不学习的时间不要超过两天。
3、要有一个帐本,哪天学会了哪几个单词,哪几个句型一定记录在案。
4、为了把单词、句型真正学到手,第二天一定要复习第一天的,第三天一定要复习第二天和第一天的内容。
5、所选择的课本可以是一套或两套,千万别太多。实际学英语的书没有什么好坏之分,只要你能按照一套或两
绿色对眼睛有好处,并不是指绿色本身对眼睛有什么好处,而是说远眺大自然的景物可缓解眼睛的疲劳状态。如果看33厘米以内的东西,即使是绿色的,对眼睛也没有益处。
