　　It may help you to know that there is no such thing as a perfect speech. At some point in every speech, every speaker says something that is not understood exactly as he has planned. Fortunately, such moments are usually not obvious to the listeners. Why? Because the listeners do not know what the speaker plans to say. They hear only what the speaker does say. If you lose your place for a moment, wrongly change the order of a couple of sentences, or forget to pause at a certain point, no one will be any the wiser. When such moments occur, don’t worry about them. Just continue as if nothing happened.
　　Even if you do make an obvious mistaring a speech, that doesn’t really matter. If you have ever listened to Martin Luther King’s famous speech — ＂I Have a Dream＂, you may notice that he stumbles (结巴)over his words twice during the speech. Most likely, however, you don’t remember. Why? Because you were fixing your attention on his message rather than on his way of speech-making.
　　People care a lot about making a mistake in a speech because they regard speech-making as a kind of performance rather than as an act of communication. They feel the listeners are lidges in an ice-skating competition. But, in fact, the listeners are not looking for a perfect performance. They are looking for a well-thought-out speech that expresses the speaker’s ideas clearly and directly. Sometimes a mistake or two can actually increase a speaker’s attractiveness by making him more human.
　　As you worr speech, don’t worry about being perfect. Once you free your mind of this, you will find it much easier to give your speech freely.

　　Recently I and other Red Cross volunteers met a group of victims from Hurricane Katrina. We were there, as mental health professionals, to offer ＂psychological first aid＂ and I was struck by the simple healing power of presence. As we walked in the gate to the shelter, we were greeted with a burst of gratitude (感激) from the first person we met. I felt appreciated, but also guilty, because I hadn’t really done anything yet.
　　I first realized the power of presence many years ago when a friend’s mother passed away unexpectedly. I had received a call saying she had just passed away. I wanted to rush down there immediately, but didn’t want to intrude (打扰) on this very personal period of sadness. I was torn about what to do. Another friend with me then said, ＂Just go. Just be there.＂ I did, and I will never regret it.
　　Since then, I have not hesitated to be in the presence of others. Once I sat at the bedside of a young man suffering from the pain of his AIDS — related dying. He was not awake, and obviously unaware of others’ presence. However, the atmosphere was by no means solemn. His family, playing guitars and singing, allowed him to be present with them as though he were still fully alive.
　　In my life, I am repeatedly struck by the healing power of presence. In it, none of us are truly alone. It is not only something we give to others but also changes me for the better.
　　1.Why were the hurricane victims grateful to the author?
　　A. He built shelters for them.
　　B. He gave immediate first aid to them.
　　C. He came to stay with them.
　　D. He brought mental health professionals.
　　2.What did the author do when his friend’s mother passed away?
　　A. He hesitated over whether to go.
　　B. He went to his friends’ at once.
　　C. He knew what to do instantly.
　　D. He decided not to disturb.
　　3.What does the underlined word ＂solemn＂ in Paragraph 3 probably mean?
　　A. Heavy but warm. 
　　B. A little sad but cosy.
　　C. Relaxing and delightful.
　　D. Very serious and unhappy.
　　4.What has the author learned from his experience?
　　A. A friend in need is a friend indeed.
　　B. Being present can make a big difference.
　　C. The family harmony is the happiest thing in life.
　　D. Being a volunteer can make one’s life more significant
　　【文章大意】本文是一篇记叙文。经过几次出现在诸如灾难现场、失去亲人的朋友家里等，作者体会到出现产生的巨大力量，因为这不仅帮助了别人，也提高了自己。
　　1.C  【解析】细节理解题。根据第一段末we were greeted with a burst of gratitude (感激)from the first person we met….I hadn’t really done anything yet.可知，我们只是和他们见面，还没有做什么，故选C。

　　Old Fossils
　　Scientists have found what they think is probably the oldest fossil on Earth, a remnant of life from 3.7 billion years ago when Earth’s skies were orange and its oceans green.
　　In a newly melted part of Greenland, Australian scientists found the leftover structure from a community of microbes（微生物）that lived on an ancient seafloor. Based on their analysis of the fossils, the researchers determined that they are 220 million years older than those discovered in Western Australia, which were 3.48 billion years old.
　　The discovery shows life may have formed quicker and more easily than once thought, about half a billion years after Earth formed. And that may also give hope for life forming elsewhere, such as Mars, said study co-author Martin VanKranendonk of the University of New South Wales and director of the Australian Center for Astrobiology. ＂It gives us an idea how our planet evolved and how life gained a foothold,＂ VanKranendonk said.
　　Scientists had thought it would take at least half a billion years for life to form after the molten Earth started to cool a bit, but this shows it could have happened quicker, he said. That’s because the newly found fossil is far too complex to have developed soon after the planet’s first life forms, he said.
　　In an outcrop of rocks that used to be covered with ice and snow which melted after an exceptionally warm spring, the Australian team found stromatolites（叠层石）, which are layered structures that are often produced by a community of microbes. The stromatolites were about 1 to 4 centimeters high.
　　＂It is like the house left behind made by the microbes,＂ VanKranendonk said. ＂Scientists used the layers of ash from volcanoes and tiny zircon（锆石） with uranium and estimated that they date back to 3.7 billion years ago.＂
　　The dating seems about right, said Abigail Allwood, a NASA astrobiologist who found the previous oldest fossil, from 3.48 billion years ago, in Australia. But Allwood said she is not completely convinced that what VanKranendonk’s team found once was alive. She said the evidence wasn’t conclusive enough that it was life and not a geologic quirk（地质巧合）. ＂It would be nice to have more evidence, but in these rocks that’s a lot to ask,＂ Allwood said in an email.
　　1. The underlined words ＂gained a foothold＂ in Paragraph 3 mean______.
　　A.continued B.changed
　　C.increased D.Started
　　2. We can learn from Paragraph 4______.
　　A.the fossil appeared soon after the birth of the earth
　　B.the fossil formed soon after the earth’s first life
　　C.life formed earlier than the newly found fossil
　　D.life appeared about half a billion years ago
　　3. What is Abigail Allwood’s attitude towards the newly found fossil?
　　A.Neutral. B.Sceptical.
　　C.Objective. D.Supportive.
　　4. According to the passage, ______.
　　A.the previous fossils are a geologic quirk
　　B. the previous fossils are made up of stromatolites
　　C. the newly found fossils come from Western Australia
