　　How to create a rocket balloon

　　To create a rocket balloon, you'll need the following items: a balloon (any size), a piece of string (10 to 25 feet), a straight drinking straw (吸管), tape. First, you have to create a “track” for the rocket balloon to run on. You begin by tying one end of the string to a tree, post, chair, or any other strong support. Then slide (使滑动) the free end of the string through the drinking straw. Tie the other end of the string to another support (generally at the same height). Make sure the string is taut(绷紧的) when tied down.

　　Move the straw to one end of the string. Fill the balloon with air. Hold the neck tightly to keep it full. Using two pieces of tape to attach the balloon to the straw. The mouth of the balloon should point toward the nearest support. Then release the balloon and watch it go!

　　When the mouth of the balloon is held closed, the air in the balloon has nowhere to go, so it pushes back to keep the balloon's shape. However, since the mouth is open when you release it, the air has somewhere to go. The air pushes out the mouth of the balloon. Since the air is now moving, the rocket balloon also moves. This follows Newton's Third Law of Motion (for every action there's an equal and opposite reaction)．

　　There is friction (摩擦) between the string and the straw, but the straw is made of material that's smooth and the weight of the balloon and straw is light, so the overall frictional force is very small.

　　It is the same when rockets work. They burn fuel to push matter out the back forcefully. The rocket moves in response to this. Since a rocket weighs much more than a balloon, of course, it takes more fuel to get it moving.

　　【诱思导学】　

　　1．Do you like doing scientific experiments? What are the stages of a scientific experiment?

　　.

　　【答案】　Yes, I do. The stages are as follows: aim—method—result—conclusion.

　　2．What will happen when the air in the balloon is receased?

　　【答案】　When the balloon's mouth is open，the air will push the balloon to move.

　　.单项填空

　　1．The wheels of the old wagon are nearly

　　those of a modern car.

　　A．twice the size B．twice size of

　　C．twice sizes of D．twice the size of

　　【解析】　考查倍数表达法。句意：古代的车轮的尺寸几乎是现代车轮的两倍。谓语后先接倍数再接adj./adv.(比较级)than或as adj./adv.(原级)as或the size/length/width/height/depth。所以选D项。

　　【答案】　D

　　2．

　　you consider，

　　you will feel.

　　A．The many；the worried

　　B．Much；much worried

　　C．The more；the more worried

　　D．Many；more worried

　　3．With time going by, he became

　　in the summer training.

　　A．more and relaxed B．more and more relaxed

　　C．more and relaxing D．more and more relaxing

　　【解析】　句意：随着时间的推移，他在这次夏季培训中越来越轻松。A项和C项这两种表达方式在英语中不存在，故排除；relaxing“令人感到轻松的”，通常用于修饰物；而此处表示人感到轻松，故选B项。

　　【答案】　B

　　4．—Do you think we need to take more clothes?

　　—Perhaps. The radio says it will be

　　tomorrow.

　　A．even cold B．a little warm

　　C．a bit colder D．a bit warm

　　【解析】　句意：——你认为我们需要多穿点衣服吗？——或许吧，收音机上说明天有点冷。B项和D项意思相同，可同时排除；even不能修饰形容词原级，故排除A项。a bit 修饰形容词比较级，也可以说a little colder。

　　【答案】　C

　　5．—Did you enjoy yourself at the party?

　　—Yes, I've never been to

　　one before.

　　A．a more excited B．the most excited

　　C．a more exciting D．the most exciting

　　五种基本句型(一)

　　英语句子有长有短，有简有繁，从现象看，似乎千变万化，难以捉摸，但从实质看，可以发现其内在联系，找出其共同规律。英语句子的基本结构可以归纳成五种基本句型及其扩大、组合、省略或倒装。掌握这五种基本句型，是掌握各种英语句子结构的基础，其他如定语、状语等均是句子的次要或附加部分。只要掌握了这五种基本句式，当遇到较复杂的句子时，运用这些基本句式进行分析，对句子的理解也就变得容易多了。在写作中，必须写好这些最基本的句型。

　　英语五种基本句型列式如下：

　　基本句型一 SV (主＋谓)

　　基本句型二 SVP (主＋系＋表)

　　基本句型三 SVO (主＋谓＋宾)

　　基本句型四 SVOiOd (主＋谓＋间宾＋直宾)

　　基本句型五 SVOC (主＋谓＋宾＋宾补)

　　一、SV (主语＋谓语)

　　　此句型的句子有一个共同特点，即句子的谓语动词都能表达完整的意思。 这类动词叫做不及物动词，后面可以跟副词、介词短语、状语从句等。

　　(1)这些动词常见的有：take place，happen，break out，appear，disappear，apologize，arrive，come，die，exist，fall，rise，hang(可作及物动词或不及物动词)等等。

　　(2)有些动词如wash，sell，burn，write，clean，draw，cook，read等等可以在后面加副词表示主语的性质。

　　1．The sun was shining.

　　2．We all breathe, eat, and drink.

　　3．Who cares?

　　4.What he said does not matter.

　　5．They talked for half an hour.

　　6．The pen writes smoothly.

　　二、SVP (主语＋系动词＋表语)

　　在该句型中，句子的谓语动词不能表达一个完整的意思，必须加上一个表明主语身份或状态的表语构成复合谓语，才能表达完整的意思。这类动词叫做连系动词。连系动词分两类：

　　(1)表示状态的连系动词。这些词有：be，look，seem，appear，smell，taste，sound，sit，stand，lie，keep，remain，stay，等等。

　　(2)表示转变或结果的系动词。这些词有：become，get，grow，turn，go，come，prove等等。
