English is a lively language, it is changing all the time, so we should keep exploring it. When we talk about exploring English, what do we explore?

And when we are traveling we say that we are in the car or the taxi, but on the train or bus! 例如，我们可以在闲暇时雕刻一座雕像(sculpt a sculpture)、画一幅画(paint a painting)，但我们只能拍一张照片(take a photo)。旅行时，我们坐汽车或出租车时是说坐在里面(in)，但是坐火车或公共汽车时却要说坐在上面(on)！ in one’s free time 在某人的空闲时间 While we’re doing all this traveling, we can get seasick at sea, airsick in the air and carsick in a car, but we don’t get homesick when we get back home. And speaking of home, why aren’t homework and housework the same thing? 同样，我们会在海上晕船(seasick at sea)、在飞机晕机(airsick in the air)、在车里晕车(carsick in a car)，但回到家里我们却不会“晕家”(homesick，实际意为“想家的，思乡的”)。说到家，为什么homework(家庭作业)和housework(家务)(这两个英语单词看起来很像意思却)不是一回事呢？ get back 回到 while 当……时 speaking of 谈到…提到…说到… If “hard” is the opposite of “soft”, why are “hardly” and “softly” not an opposing pair? If harmless actions are the opposite of harmful actions, why are shameless and shameful behaviors the same? 同样，如果说硬)是soft(软)的反义词，为什么hardly(几乎不)和softly(柔和地，)却不是一对反义词呢？如果说harmless actions(无害的行为)与harmful actions(有害的行为)意思相反，为什么无耻的行为(shameless behaviors)和可耻的行为(shameful behaviors)反而是一回事？ opposing adj.相反的 opposite n.反面 adj.相反的 be opposite to 与……相反 形容词后缀 ：less 无/不… ful 充满/有…（hopeful，helpful，useful） careless马虎的，hopeless, useless hopeful，helpful，useful） When we look out of the window and see rain or snow, we can say “it’s raining” or “it’s snowing”. But when we see sunshine, we can’t say “it’s sunshining”. 当我们望向窗外，看到雨(rain)或雪(snow)时，我们可以说正在下雨(it’s raining)或正在下雪(it’s snowing)。但当我们看到阳光(sunshine)时，我们不能说“正在下阳光”(it’s sunshining)。 look out of 往外看 The sun is shinning. 阳光明媚 Even the smallest of words can be confusing. When you see the capitalized “WHO” in a medical report, do you read it as the “who” in “Who’s that?” What about “IT” and “US”？ 即使是最短小的单词都让人费解。当你在医学报告中看到大写的WHO时，你会把它读为Who’s that?中的who吗？那么“IT”和“US”又该怎么读呢？ confusing adj.（事物）令人困惑的 confused adj. （人）感到困惑的 confuse v. 使混乱，使困惑 confusion n. 混淆，混乱，困惑 in confusion困惑地 You also have to wonder at the unique madness of a language in which a house can burn up as it burns down, in which you fill in a form by filling it out, and in which an alarm is only heard once it goes off! 你也会对英语这门语言独有的疯狂感到惊奇。在英语里，房子烧成灰烬时，可以说burn up(字面意思是“烧上去”)，也可以说burn down(字面意思是“烧下去”)；填表时，你可以说fill in a form(字面意思是“填入表里”)，也可以说fill out a form(字面意思是“填到表外”)；而且只有闹钟走了(go off字面意思是“离开”)以后你才能听到铃声 wonder at 对…感到惊奇 unique 独特的 be unique to 对…来说很独特 uniqueness n. mad adj.疯狂的 madness n. 疯狂 That is why when the stars are out, they are visible, but when the lights are out, they are invisible. And that is why when I wind up my watch, it starts, but when I wind up this passage, it ends. 这就是为什么stars are out(星星出现了)时，我们能看到星星，而当lights are out(灯光熄灭)时，我们却看不到灯光。这也是当我wind up my watch(给手表上发条)以后表针开始走，而我wind up this passage(将本文收尾)后这篇文章结束的原因。 That is why...意为“这就是为什么……”，指结果。 That is because...意为“这就是因为……”，指原因 The reason why...is that... ……的原因是…… The reason why she was crying was that she became homesick. 表语从句 1.I have much trouble _____ speaking English. 2.The ground must be just right neither too wet ______ too dry. 3.I have no trouble _____ my English study. 4.Speaking ______ honesty, I know a lot of people who don't pay bus fares. 5.I wonder _____ your allowing her to do such a thing. 6.In western culture, and if a problem, the best way is to speak _____ directly. 7.The student filled _____ the application form. 8.The alarm went _____. 用适当的介词或连词填空。 in nor with of at out out off Thank you!
