Unit1 summary
本单元的中心话题是“科学家”，涉及到科学家的名言，轶事，科学家的成功之道，如何向科学家学习等。

语言技能和语言知识几乎都围绕这一中心话题展开的，学生们比较感兴趣，speaking部分都有话可说，积极性很高，课堂气氛活跃。

Reading 部分介绍了著名物理学家斯蒂芬霍金的生平，他的一系列探索发现和他对科学研究的态度，观点，他不为病魔和瘫痪所吓倒，而以惊人的毅力和信心成为物理界探索宇宙的先锋，本课不仅让同学们学到了语言知识，而且还学到了勇于探索，不怕困难的精神，并且乐观向上的面对生活。

本单元的语法项目是不定式的练习。

在课堂上我通过给学生们分类，句型改写等练习使他们进一步理解和掌握动词不定式的用法。

本单元教学中最深的体会：让学生们自己用新词汇造句，每个句子至少有一个动词不定式。

效果很好。

本单元教学不足之处：听力教学效果不够理想，有待改进。

The Spirit rover went for its longest trip on the surface of Mars (火星), traveling just over 26.4meters but stopping short of the distance NASA has hoped it would cover, scientists said today.
Engineers had hoped the rover would travel 49.2 meters on its way to a crater known as “Bonneville” to examine rocks and soil for evidence(证据)that water may gave existed on the Red Planet, mission manager Jim Erickson said.
“Spirit. she’s put some more territory behind her,” Erickson said. “We’re close but not as close as we’d wanted to be.”
Spirit’s longest previous distanc e covered in a day was 21 meters. That occurred last week. Before setting off for the crater. Spirit made a careful study of a flaky(有薄层的)rock called “Mini”.
Scientists want to know why the rock is flaky when nearby rocks are not. Erickson said flakiness may indicate layering-a
possible sigh the rock was formed over time instead of all at once, as may be the case with spit from a volcano. Scientists at the National Aeronautics and Space Administration reconsidered their judgment of the distance to the “Bonneville” crater, saying it’s about 345meters from Spirit’s landing place. The robot still has 240meters to got to reach.
36. Which of the following would be the best title of this passage?
A. Worries of the NASA about the Mars rover
B. Long way for Spirit to go
C. The longest walk of Mars rover up to now
D. Unexpected problems the NASA met with
37. The Spirit rover had covered about meters in all when the news was given.
A. 49
B.76

A. she was ordered to examine some other rocks and soil
B. it took her more time than expected to study rocks and soil on her way

News has just been received of an air crash in the north of
England. The plane, which was on a charter (包租的) flight from London to Carlisl, was carrying a party of businessmen on their way to a trade fair. It seems likely that the plane ran into a heavy fog as it was getting close to Carlisle and was forced to circle for some twenty minutes. Everything seems to be going well. The pilot was in constant radio communication with Control, when the engines suddenly cut out and all contact was lost. The plane crashed on the site of the ancient Roman camp at Hadrian’s Hill, a place well known to archaeologists(考古学家) and tourists.
So far few details have been reported, but it is feared that at least twenty people lost their lives, among whom was the pilot, who was killed instantly. The local ambulance and firemen were on the scene within minutes of the crash, but additional help had to be rushed from other areas.
Mr. Lesilie Collins, one of the survivors, told our reporter, “We passengers noticed the engines were making a funny noise. Of course we couldn’t see anything becaus e of the fog, but the pilot said there was nothing to worry about. The next thing, we know, the engines went dead. There was a rushing noise and a kind of flash-and after that I don’t remember any more.”
Mr. Collins is now in hospital, being treated for minor injures. We will be bringing you further news of the crash as we receive it. In the meantime relatives are asked to ring 023457211 for information.
