课文再现
Scientists think that there has been life on the earth for hundreds of millions of years. However, we have not found life on any other planets yet.
The sun and its planets are called the solar system, and our solar system is a small part of a much larger group of stars and planets, called the Galaxy or the Milky Way.
Scientists have also discovered many other galaxies in the universe. Scientists have sent spaceships to the planet Mars to take photos. They have even sent spaceships to travel outside the solar system. However, no spaceship has travelled far enough to reach other stars in our Galaxy.
Scientists have always asked some questions: Have there been visitors to the earth from other planets Why has no one communicated with us We do not know the answers…yet.

语法精讲
现在完成时(2)
命题情报
现在完成时有很多较为明显和常用的特征词，如： just，already和yet。注意区别它们之间的用法，如 already和yet。现在完成时与一般过去时的区别也是一 个重要考点。
1 用法(一)
现在完成时表示过去发生或已经完成的某 一动作对现在造成的影响或结果。此时，常与 already，yet，just，ever，never，before等连用。 这几个副词的用法如下：
1. already意为“已经”，通常用于肯定句，可以 放在助动词之后，过去分词之前，也可以放在 句末。
I’ve already read this book. 我已经读过这本书 了。(“读”这一动作发生在过去，对现在造成 的影响是“知道书中的内容”。)
2. yet用在疑问句中，意为“已经”；用在否定句 中，意为“还”。yet常放在句末。
—Has he found his watch yet
他已经找到他的手表了吗
—No, not yet. 不，还没有。
3. just意为“刚刚”，表示动作刚刚发生，常放在助 动词与过去分词之间。
He has just come back from school. 他刚从学校回来。
4. ever意为“曾经”，用于疑问句或否定句，放在 助动词与过去分词之间。
Have you ever been to Hong Kong 你曾去过香港吗
5. never意为“从来没有”，常与before 连用。(before要放在句末，而never 多放在助动词与过去分词之间。)
I have never travelled by plane before.
我以前从来没有乘飞机旅行过。
2 现在完成时与一般过去时的区别
1. 现在完成时：表示过去发生的动作对现在造成了 影响或产生了结果，不与确定的表示过去的时间 状语连用。
Jill has bought a new computer.
吉尔买了一台新电脑。(着重点是现 在有了一台新电脑)
标志词：ever, already, never, yet, since, recently, for, in the last/past five years, twice等。
试比较：
①Have you seen the film (A)
Did you see the film (B)
你看过这部电影吗
A句强调的是被问者对剧情是否了解；而B句强调 的是看这部电影的动作是否发生过，并不强调是 否知道其内容。
② He has lived in Beijing for 8 years. (A)
He lived in Beijing for 8 years. (B)
他在北京住了8年。
A句强调的是到目前为止，他在北京住了8年，可 能还会继续在北京住下去；B句强调的是他在北 京住过8年，现在不在北京住了。
2. 一般过去时：表示过去某个时间发生的事情、存 在的状态或发生的动作。侧重点在于陈述一件过 去的事情，不强调对现在产生的影响。
He visited Guilin in 1998.
他1998年游览过桂林。(只说明去桂林的时间)
标志词：…year(s) ago, yesterday, the day before yesterday, last week, in 2000, just now, at the age of等。

Many students took an active part in the party, and their songs were very nice. Finally, we made a telephone call with aliens. We all had a good time.
The trip was very interesting and I'll never forget the trip. I hope to travel to Mars again.
判断正误题
判断正误题主要考查我们对文章的具体事实、信息的理解能力，一般是根据文章的事实或细节，给出一 个或几个句子，判断其正误。如果是判断一个句子的正误，难度相对较小。如果是判断多个句子的正误，难 度相对较大，可通过认定法(认定某个句子是正确的或者错误的)，也可以通过排除法(通过断定其他几个选项的正误，推断出其中一个为正确的或者错误的选项)。主要方法如下：
培优课堂　　　　　　
1. 仔细阅读文章后面的“问题”，把握每个待定“问题”的含义。
2. 带着“问题”快速阅读短文，把握文章大意，明确作者的观点和态度，寻找所需要的信息。
3. 通过寻读法在原文中找出与每个“问题”相关的词句或段落，从中找到判断的依据，对“问题”进行 是非判断，不能凭想象和想当然。
对一些似是而非的句子，一定要认真识别，只有完全符合文章意思的方可判定为正确。对那些意思基本 相符，却仍有一点不符合的应判定为错误。
出题方式一般如下：
1. Which of the following is TRUE according to the passage
2. Which of the following is NOT true according to the passage
3. 根据短文内容，判断下列句子是否正确，正确的填“T”，错误的填“F”。 The Jacksons are from England. ( )
4. According to the news/passage above, which of the following is TRUE
【典例】
On the second Sunday in May is Mother’s Day. American children of all ages give their mothers something special. It is the day children, young and old, try to show their love to their mothers. It is the day to celebrate motherhood and to thank Mother for all small and big things she has done for her children. However, did you know that Mother’s Day celebration is no recent thing
England was the first country to set a day to mothers. In the United States, Mother’s Day became an official holiday in 1910. An American girl, Anna, asked her governor to set a festival for mothers for their love. And they set the second Sunday in May as Mother’s Day and a year later all the other states celebrated it.
On Mother’s Day morning some American children serve their mothers breakfast in bed. Other children will give their mothers presents which they have made themselves or bought in stores. Adults give their mothers red carnations(康乃馨), the official Mother’s Day f lower. If their mothers left the world, they may bring white carnations to their grave sites(墓地). This is the busiest day of the year for American restaurants. On the special day, family members do not want Mum to cook dinner!
【题目】 Which of the following is TRUE according to the
passage
A. Only young children buy presents for their mothers.
B. Anna wanted to set the festival for only her mother.
C. Not all the states want to celebrate Mother’s Day.
D. Some mothers can eat breakfast in bed on Mother’s
Day.
【答案】D
【解析】本题是判断正误题。此处使用认定法。由第三段的第一句“On Mother’s Day morning some American children serve their mothers breakfast in bed.”可知，在母亲节的早上，一些美国孩子给他们的母亲在床上提供 早餐。D项符合题意。
