【语篇解读】 作者与丈夫在外旅行时，不慎将钱包丢失在人行道上，幸遇好心人，钱包失而复得。
1．When/While 考查时间状语从句。when表示“当……的时候”，引导时间状语从句。句意：我们享受波特兰这座城市的美景，我们住在当地的一个宾馆里。
2．containing 考查非谓语动词。a wallet与contain之间是逻辑上的主谓关系，应用动词的－ing形式作后置定语，相当于定语从句which contained over $500，修饰名词wallet。
3．of 考查介词。be unaware of表示“没有意识到；未察觉”，为固定搭配。 4．from 考查介词。作者收到一条来自宾馆经理的语音信息，因此用from，表示“来自……”。
5．that 考查定语从句。空处引导定语从句，并在从句中作主语，修饰先行词something，故用that。
6．the 考查冠词。特指前面提到的那个钱包，因此应用定冠词the。
7．found 考查动词的时态。男孩在路上发现钱包，之后把它拿给爸爸。发现钱包这一动作发生在过去，故用过去时态。该句中的brought也是提示。
8．someone/somebody 考查代词。根据空后的“who”可知应是人。表示“某人”，应用不定代词someone或somebody。
9．What 考查感叹句。此处表达作者的赞叹。what引导感叹句，句式为：What＋adj.＋n.＋主语＋谓语……！how引导感叹句，句式为：How＋adj.或adv.＋主语＋谓语……！由“wonderful people”可知，应填What。
10．honesty 考查词性转换。名词honesty作appreciate的宾语。 Ⅱ.阅读理解

(2013·徐州模拟)The year is 2094. It has been announced that a comet(彗星) is heading towards the Earth. Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July, a piece four kilometers wide enters the Earth's atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won't escape for long. Because of the explosions, the sun is hidden by clouds of dust, and temperatures around the world fall to almost zero. Crops are ruined. The sun won't be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million remain alive.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn't live through the cold climate that followed and they died out. Will we meet the same end?

B．Because the light and heat from the sun cannot reach the Earth. C．Because people there cannot live at the temperature of zero. D．Because wars break out among countries.

(2013·郑州一中月考)Do you want to live forever？By the year 2050，you might actually get your wish—if you are willing to leave your biological body and live in silicon circuits(半导体电路)．But long before then，perhaps as early as 2015，some measures will begin offering a semblance of immortality(虚拟的永生)．
Researchers are confident that technology will soon be able to track every waking moment of your life.Whatever you see and hear，all that you say and write，can be recorded，analyzed and added to your personal chronicles(履历)．By the year 2030，it may be possible to catch your nervous systems through electrical activities，which would also keep your thoughts and emotions.Researchers at the laboratories of British Telecommunications have given the name of this idea as Soul Catcher.
Small electronic equipment will make preparation for Soul Catcher.It would use a wearable supercomputer，perhaps in a wristwatch，with wireless links to micro sensors under your scalp(头皮)and in the nerves that carry all five sensory signals.So wearing a video camera would no longer be required.
