International Tiger Day is an annual celebration to raise the awareness of tiger conservation.It's held on 29 July.Governments and citizens across the world organize awareness programs on that day to spread the importance of protecting tigers.
From ancient times, tigers were the subject of constant attraction for their beauty, size and sometimes mythical (神話的) stories related to them.People's fascination (迷戀) for tigers is obvious from the fact that tigers are still a part of many national symbols and flags.Tigers are the largest cat species.Unfortunately, the population of tigers is fast decreasing.Every part of tigers from tail to skin to nail is traded in the illegal market for very high values.Many tigers are hunted, which is one of the key threats to their existence.They are also caught and raised as pets.97 percent of the world tiger populations decreased in the last 100 years and only 3，890 tigers are left.If tigers get extinct, we will lose a species.And it also means that enough forests have been destroyed, which may endanger many other species.
For us, tigers are symbols of wildlife's fighting for survival.It reminds us of the dangers we face because of people's over-exploitation (過(guò)度開(kāi)發(fā)) of the nature.It's an opportunity as well.Many efforts are on the way to double the tiger population by 2022.Strict national and international laws are against hunting and trading tigers.As a result, the number of tigers in the wild has risen for the first time in more than 100 years.Even though this is just a small increase, it's a huge symbolic victory in our efforts against the destruction of forests and wildlife.It's very important that we all join together in this effort, not only to save tigers, but also to save our forests.
語(yǔ)篇解讀：本文是一篇說(shuō)明文。文章主要講述了由于種種原因，老虎一直成為人類獵殺的動(dòng)物并瀕臨滅絕，現(xiàn)在人類正為保護(hù)老虎做出種種努力。

A．Tigers are uncommon.
B．Tigers might destroy their homes.
C．Tigers are very dangerous animals.
D．Tigers can be used to show a nation's spirit.
解析：選D　推理判斷題。根據(jù)第二段中的People's fascination (迷戀) for tigers is obvious from the fact that tigers are still a part of many national symbols and flags.可推斷，人們認(rèn)為老虎是他們國(guó)家精神的象征，因此其圖案常出現(xiàn)在國(guó)旗上。
3．The population of tigers is fast decreasing mainly because ．
A．they are hunted for trade in illegal markets
B．they are not as healthy as before
C．many people keep them as pets
D．some of them are kept in zoos
解析：選A　細(xì)節(jié)理解題。根據(jù)第二段中的Every part of tigers from tail to skin to nail is traded in the illegal market for very high values.Many tigers are hunted, which is one of the key threats to their existence.可知，老虎在市場(chǎng)上被非法買賣是造成其數(shù)量快速減少的主要原因。

B．We should put more effort into protecting tigers.

B
One night, I was happily making my tea when all of a sudden the room was in complete darkness.The lights had gone out, the oven (烤箱) stopped working and my phone was no longer charging (充電).I tried to fix the electricity but I soon realized that I couldn't.I had to wait for an electrician to come in the morning.
After messaging my friends to say that I wouldn't message that night because I couldn't charge my phone, I sat down to eat my half-cooked dinner.And then I wasn't sure what to do.I usually spend my evenings watching TV and going on the Internet.I couldn't even read a book because I wasn't prepared with candles.So for me, it was an early night．
Losing our electricity felt like losing a basic necessity.In fact, electricity is a luxury (奢侈品).But we think it will always be there when we need it.I use electricity all the time, even when it's not really necessary.I use it to put the TV on even when I'm not really watching it.I use it to check my phone when I wait for a friend.
Our overuse of electricity is a big problem.It is one of the causes of global (全球的) warming, which is harming our environment and we need to do what we can to stop it.Not only that, but if we continue to overuse it we will soon run out.
We wouldn't want to live in a world without electricity, but we will run out one day.So, shouldn't we start preparing for it now? Cutting back on our use of electricity saves energy resources (資源) so that they can last longer.I know for sure that I could cut down on my use of electricity.If everyone does the same, we can make a difference.
語(yǔ)篇解讀：本文是一篇記敘文。經(jīng)過(guò)一次停電事件，作者開(kāi)始反思自己過(guò)度依賴和浪費(fèi)電資源的情況，呼吁大家節(jié)約能源。
5．What did the author do when the electricity went out suddenly?
A．He tried to fix it and succeeded.
B．He messaged his friends for help.
C．He called an electrician immediately.
D．He stayed in darkness the whole night.
解析：選D　推理判斷題。由第一段中的I had to wait for an electrician to come in the morning.和第二段中的I wasn't prepared with candles可知，突然停電之后，作者只能等待電工第二天早晨來(lái)修，而且作者沒(méi)有準(zhǔn)備蠟燭，因此可推斷，作者不得不整夜處在黑暗之中。
6．What does the underlined sentence in Paragraph 2 show?
A．The author was unsure what to do.
B．The author had nothing to do but sleep.
C．The author was tired after the accident.
D．The author didn't want to do any reading.
解析：選B　句意理解題。由第二段內(nèi)容可知，由于停電，作者無(wú)法做自己平時(shí)所做的事情，作者也沒(méi)有準(zhǔn)備蠟燭，無(wú)法讀書，因此只能早睡。
7．What is Paragraph 4 mainly about?
A．The results of overusing electricity.
B．The examples of overusing electricity.
C．The ways of using electricity properly.
D．The suggestions on producing electricity.
解析：選A　段落大意題。第四段主要介紹了過(guò)度使用電資源的后果：導(dǎo)致全球變暖，進(jìn)而危害環(huán)境，而且過(guò)量使用電資源會(huì)使其很快耗盡。
