答案与解析　
语篇解读　这是感恩节当天，中国留同学Steve和美国同学Alice的英语口语对话。美国的圣诞节和感恩节就像中国的春节一样，全家会吃团聚饭。Alice具体地对Steve介绍了在美国常见的感恩节食物。
1．friends　被all修饰， friend是可数名词，需用复数形式。
2．going to do　对话中说的是要过感恩节，因此是感恩节的时候会做什么，因此用be going to表将来。误会分析：此处假如没有结合语境及语法常识，就简洁出错。
3．If　此处是表条件含义，因此用if引导条件状语从句。
4．to come　would like/love后需接动词不定式。
5．wonderful　此处表达“好极了”，因此用wonderful作表语。
6．how　依据语境可知，此处表示去看看其他家庭如何过感恩节，因此用how。
7．a　此处表“一次大型的家庭聚会”之意，因此用a。
8．like/such as　前面提及lots of delicious food，此处举例，因此用like或such as。
9．sounds　本段对话是现在的事情，且主语是第三人称单数形式，用sounds。
10．it　此处表示“想到感恩节大餐就饿了”，因此用it代指。语 篇 提 能
Ⅳ.阅读理解

In early October, thousands of people around the globe stepped outside to gaze at their local night sky. As part of an event called the Great World Wide Star Count, adults and kids looked for one of two constellations (星座) — Cygnus in the Northern Hemisphere and Sagittarius in the Southern Hemisphere. The observers recorded how many stars they saw and how bright the stars were, and then posted their results online.
The Star Count was part of a global effort to help scientists learn more about how light pollution affects our view of the night sky. Whether participants saw thousands of stars — or just a dozen — depended a lot on whether they were surrounded by darkness or by twinkling city lights.
On a clear night, with no clouds, moonlight, or artificial lights to block the view, people can see more than 14,000 stars in the sky, but when people are surrounded by city lights they're lucky to see 150 stars.
If you've ever driven toward a big city at night and seen its glow from afar, you've witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates the night sky. This light makes many stars invisible to people on earth.
Dust and particles of pollution from factories and industries worsen the effects of light pollution. When these particles float into the atmosphere, light ricochets (跳飞) off of them and scatters even more.
Light pollution doesn't only affect star visibility. It can harm wildlife too. Scientists don't entirely understand how animals navigate at night, but it's clear that artificial light can attract them, making them go off course. There's increasing evidence, for example, that migrating birds use sunsets and sunrises to help find their way.
1．Why do many people look at the local sky?
A．To enjoy the beauty of the stars.
B. To develop their interest in Astronomy.
C. To help scientists do a research on light pollution.
D. To get the exact number of stars in the sky.
答案与解析　C　细节理解题。依据第一段最终一句和其次段第一句可知，他们参与 the Great World Wide Star Count活动的目的是挂念科学家更深化地了解光污染在夜晚对人们视野的影响。
2．When people are surrounded by artificial lights, ________.
A．they can find more stars in the sky
B. the stars might appear more clearly
C. the stars seem to be bigger
D. they can find far fewer stars
答案与解析　D　推理推断题。依据第三段可知，正常状况下人们能看到14000颗星星，但是在有人造光时只能看到150颗，所以要少得多。
3．The following things make light pollution worse EXCEPT ________.
A．artificial lights B. stars
C. dust D. particles
答案与解析　B　细节理解题。依据第三段中artificial lights和第五段第一句可排解B项。
4．How does light pollution affect birds?
A．It does great harm to their eyes at night.
B. It misleads them the way when they migrate.
C. It can enable them to see their routes clearly.
D. It can make them find their way easily.
答案与解析　B　推理推断题。依据最终一段可知，人造光吸引鸟类，使它们偏离飞行路线。

Ⅵ.短文改错
Dear Mayor,
I'm a resident of the city. I feel there are many problems existed in the trade of taxis in our city. First of all, there aren't enough stops in the streets. And taxis often run very fast, which caused many traffic accidents. Additional, some taxi drivers refuse to pick some passengers without any reason. Another terrible thing is that deeply at night taxis waiting around entertainment places make too much noise. A friend of mine living in another city once visited to me, and she told me a taxi driver once cheated her by taking a roundabout route. How will a guest think of our city after such bad experience?
I think we must take actions to tighten control over the taxi trade. The last thing to do is raise the taxi drivers' professional morality.
Sincerely yours，
Chris
