教学过程
Step 1 Warming up
1.Brain storming: Let students think them over and discuss in groups:
How many planets are there in the solar system? What are they?
Is there any life on other planets?
Ask the students to have a discussion and think them over. Then, the teacher shows students the pictures of eight planets.
3.Tell students some background information of people’s effort to land on the moon home and abroad.
Step 2 Pre-reading
Ask students to work in pairs to talk about Shenzhou-9—a man-made spaceship.
What do you know about it？
Step 3 Fast-reading
Read the passage and choose the best title for it.
1.Anyone out there? 2. Life on the earth

Para 2: Ask students to read and match the words with pictures.
Then put the words in the box in order: small—large.
Paras 3-4：Ask students to read and complete the table.

4 Ask students to act out.
Step 6 Language points
However, we have not found life on any other planets yet.
但是，我们在其他星球上还没有发现生命。
other 形容词，意为“其他的”，用于修饰名词。
辨析：the other (s)与other (s）：
the other与other后可加名词; the others与others后不加名词；the other (s)表示一定范围内除去一部分以外后其余的全体；other (s)表示除去一部分以后的（一些）,但不是剩下的全体。
One flower is red, and the other (one) is white.
一朵花是红的，另一朵 (花)是白的。
Give me some other apples/others, please!请另给我一些（苹果）吧！
It is taller than many other buildings.它比许多其他的建筑物都高。
None of them has an environment like that of the earth.
它们中没有一个有像地球这样的环境。
辨析：no one与none：
no one的同义词为 nobody, 只用于指人，其后不跟of短语，作主语时谓语用单数，no one 只能回答who提问的问句。
none用于表示对三者或三者以上全部否定，既可指人，也可指物,常用于短语none of+名词复数/代词，表示 “……中没有一个”。作主语时，谓语可以是单数，也可以是复数; none的反义词是all, none可与of连用; 可以用来回答how many 或 how much提问的问句。
None of us are/is interested in the story.我们没有人对那个故事感兴趣。
None of the students in this class has been to England.
这个班没有一个学生去过英国。
—Who are you speaking to?你在跟谁讲话？
—No one. 没人。
—How many students are there in the room?房间里有多少个学生?
—None. 一个也没有。
3. ...with so many stars in the universe, are we alone...?
……宇宙中有这么多的恒星，我们是唯一的吗……？
辨析：alone与lonely
alone既可作形容词，又可作副词,意为“单独的/地，独自的/地”，没有感彩。
She is afraid of going out alone at night.晚上她害怕一个人出去。
(2) lonely形容词，意为“孤独的，寂寞的”，具有感彩。
He lived alone after his wife left，so he was very lonely.
他妻子离开后，他一个人生活，所以他很孤独。
Do you feel lonely when you are at home alone?
你自己一个人在家时感到孤独吗？

But 2 of them has a(n) 3 like that of the earth. Spaceships from the earth have done surveys of the other planets, but they have not found any life there. Why has no one from other planets tried to 4 with us? It is true that scientists have not discovered life on other planets in the 5 yet, but some scientists believe that they will find it some day.

universe
Step 8 Writing
1.Let students look at the picture from a science story for children and answer the questions.(A5)
— What have the scientists just received?
— They’ve just received a message from one of our spaceships.
(1) Where has the spaceship landed? (Mars)
(2) What has the spaceship discovered? (people on Mars)
(3)Why have the people on Mars not sent us a message? (don’t know how to)
(4)Why have the people on Mars not visited us on the earth?(don’t know how to)
2. Let students write a passage to describe the picture. Tell them to use their answers to the questions in Activity 5 to help them.
We have just received a message from our spaceship to Mars…
Possible version:
We have just received a message from our spaceship to Mars. Our spaceship has discovered aliens there. They have never sent us a message because they don’t know how to communicate with us. They haven’t visited the earth because they don’t know how to fly to our planet, and they prefer life on Mars. They seem very happy on their planet. They have used parts from the other spacecraft from the earth to make TVs, radios, etc. We hope they don’t do the same with this one!

教学过程
Step 1 Warming up
Tell students to read the sentences on the textbook. Pay attention to just, yet, already.
I’ve just made a model spaceship.
We have not found life on any other planets yet.
Astronauts have already been to the moon.
Has it arrived yet?
Step 2 Grammar learning（现在完成时）
现在完成时的意义：表达“某人曾经做过某事”“某人已经做了某事”或者“某人刚刚做某事”等意思。
现在完成时的结构：
has/have+done (动词过去分词)
现在完成时的句式结构:
肯定句:Sb.+have/has + done+...
否定句：Sb.+haven’t/hasn’t + done+...
一般疑问句：Have/Has +sb.+done+...
特殊疑问句：Wh-（疑问词）+have/has+(sb.+)done+...
现在完成时的标志词：
与现在完成时连用的几个副词：
肯定句:already, just
疑问句和否定句: ever, yet, never
注意：yet 常置于句末，而already, never, ever, just一般置于助动词have/has之后，动词过去分词之前。
【辨析】have been to 与 have gone to
have gone to表示“去了某地”。说话时该人不在现场，强调尚未回来（go是方向性动词）。
—Where is Jim? 吉姆在哪里？
—He has gone to Beijing.他去北京了。
have been to表示“曾经去过某地”。现在已经不在那里了（be表示状态），后可接次数，如once, twice, three times等，表示“去过某地几次”。也可和just, never和ever等连用。
I have been to Beijing twice.我去过北京两次。
【拓展】have been at/in表示“在某地待了多长时间”，常与表示时间段的状语连用。
I have been in Shanghai for three years.我来上海已有三年了。
