The moon is about 384,000 kilometers 28 the earth. A plane can not fly to the moon because there isn’t enough air. But a rocket can fly even when there is no air.
“How does a rocket fly?” If you want to know, get a balloon and then blow it up 29 it is quite big. Do not 30 the neck of the balloon. Let it go 31 and see 32 happens. The balloon will fly off through the air very quickly. The air inside the balloon 33 out. It rushes out through the neck balloon and this pushes the balloon through the air.

A
Our eating habits are very
important for good health and a strong body. There are times when most of us
would rather eat sweets and ice-cream than meat and rice. Sweets and ice-cream
are not bad if we eat them at the end of a meal. If we eat them before a meal,
they may take away our appetite(食欲).
It is important for us to eat our meals at the same time each day. When we feel
hungry, it is a sign that our body needs food. When we feel angry or excited,
we may not want to eat. A long time ago, in
41. It is good to eat sweets and ice-cream ____.

B
People in the United States honor their parents with two special days：Mother’s Day, on the second Sunday in May，and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care. These two days make us think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child care.
These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery(墓地). On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.
Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries, telephone companies, and other stores do a lot of business during these holidays.
44. Which of the following is NOT a reason for children to show love and respect for parents?
A. Parents bring up children.
B. Parents give love and care to children.
C. Parents educate children to be good persons.
D. Parents pass away before children grow up.
45．What do you think “florists” do?
A．They sell flowers.
B．They make and sell bread.
C．They offer enough room for having family parties.
D．They sell special gifts for Mother’s Day and Father’s Day.
46．What do you know from the passage?
A. Mother’s Day and Father’s Day are both in May.
B. Fewer women worked outside the home in the past.
C. Not all the children respect their parents.
D. Fathers are not as important as mothers at home.
47．On Mother’s Day and Father’s Day,__________.
A. people usually have family parties
B. everyone goes to visit the cemetery
C. children always go to parents’ home
D. hand-made cards are the most valuable gifts
C
If you go into the forest with friends, stay with them． If you don’t, you may get lost． If you get lost, this is what you should do． Sit down and stay where you are． Don’t try to find your friends―let them find you. You can help them find you by staying in one place．There is another way to help your friends or other people to find you．You can shout or whistle three times．Stop．Then shout or whistle three times again．Any signal given three times is a call for help．
Keep up shouting or whistling. Always three times together． When people hear you, they will know that you are not just making a noise for fun． They will let you know that they have heard your signal． They will give you two shouts or two whistles． When a signal is given twice, it is an answer to a call for help. If you don’t think that you will get help before night comes, try to make a little house with branches. Make yourself a bed with leaves and grass．
When you need some water, you have to leave your little branch house to look for it. Don’t just walk away．Pick off small branches and drop them as you walk in order to go back again easily. When you are lost, the most important thing to do is to stay in one place．
48．If you get lost in the forest, you should___________．

How much
paper do you use every year? Maybe you can’t answer this question quickly. In
1900 the world’s use of paper was about one kilogram for each person in a year.
Now some countries use 50 kilograms of paper for each person in a year. But
countries like
Paper was first made in
When
we think of paper, we think of newspapers, books and writing paper. But there
are many other uses. Only half of the paper is used for books and things like
that. Paper is very good for keeping you warm. Houses are often insulated(使絕緣, 隔離 ) with
paper. You may see some men asleep on a large number of newspapers. They’re
insulating themselves from the cold. In
Each year more and more things are made of paper. We have had paper cups and plates for a long time. But now we hear that chairs, tables and even beds can be made of paper. With paper boots and shoes, you can wear paper hats, paper dresses and paper raincoats. When you have used them away and buy new ones. People have made paper boats, but they haven’t made paper planes or cars. Just wait they perhaps will.

高中物理公式、規律匯編表
一、力學
1、胡克定律：f = kx (x為伸長量或壓縮量，k為勁度系數，只與彈簧的長度、粗細和材料有關)
2、重力： G = mg (g隨高度、緯度、地質結構而變化)
3、求F1、F2的合力的公式： 
兩個分力垂直時： 
注意：(1) 力的合成和分解都均遵從平行四邊行定則。
(2) 兩個力的合力范圍：ú F1－F
(3) 合力大小可以大于分力、也可以小于分力、也可以等于分力。
4、物體平衡條件： F合=0
或 Fx合=0 Fy合=0
推論：三個共點力作用于物體而平衡，任意一個力與剩余二個力的合力一定等值反向。
5、摩擦力的公式：
(1 ) 滑動摩擦力： f = mN
說明：①N為接觸面間的彈力，可以大于G；也可以等于G；也可以小于G。
②m為動摩擦因數，只與接觸面材料和粗糙程度有關，與接觸面積大小、接觸面相對運動快慢以及正壓力N無關。
(2 ) 靜摩擦力： 由物體的平衡條件或牛頓第二定律求解，與正壓力無關。
大小范圍：
說明：①摩擦力可以與運動方向相同，也可以與運動方向相反。
②摩擦力可以作正功，也可以作負功，還可以不作功。
③摩擦力的方向與物體間相對運動的方向或相對運動趨勢的方向相反。
④靜止的物體可以受滑動摩擦力的作用，運動的物體可以受靜摩擦力的作用。
6、 萬有引力：
（1）公式：F=G
（適用條件：只適用于質點間的相互作用）
G為萬有引力恒量：G = 6.67×10-11 N?m2 / kg2
（2）在天文上的應用：（M：天體質量；R：天體半徑；g：天體表面重力加速度；r表示衛星或行星的軌道半徑，h表示離地面或天體表面的高度））
a 、萬有引力=向心力 F萬=F向
即 
由此可得：
①天體的質量： ，注意是被圍繞天體（處于圓心處）的質量。
 |
②行星或衛星做勻速圓周運動的線速度： ，軌道半徑越大，線速度越小。
③ 行星或衛星做勻速圓周運動的角速度： ，軌道半徑越大，角速度越小。
④行星或衛星做勻速圓周運動的周期： ，軌道半徑越大，周期越大。
 |
⑤行星或衛星做勻速圓周運動的軌道半徑： ，周期越大，軌道半徑越大。
⑥行星或衛星做勻速圓周運動的向心加速度：
，軌道半徑越大，向心加速度越小。
⑦地球或天體重力加速度隨高度的變化：
特別地，在天體或地球表面：
⑧天體的平均密度：
特別地：當r=R時：
b、在地球表面或地面附近的物體所受的重力等于地球對物體的引力，即
∴
。在不知地球質量的情況下可用其半徑和表面的重力加速度來表示，此式在天體運動問題中經常應用，稱為黃金代換式。
c、第一宇宙速度
：第一宇宙速度在地面附近繞地球做勻速圓周運動所必須具有的速度。也是人造衛星的最小發射速度。
第二宇宙速度：v2=
第三宇宙速度：v3=
7、 牛頓第二定律： 
理解：（1）矢量性 （2）瞬時性 （3）獨立性 （4）同體性 （5）同系性 （6）同單位制
8、勻變速直線運動：
幾個重要推論：
（1）
（2）A B段中間時刻的即時速度：
（3）AB段位移中點的即時速度：
勻速：vt/2 =vs/2 ，勻加速或勻減速直線運動：vt/2 <vs/2
（4） 初速為零的勻加速直線運動,
① 在1s 、2s、3s……ns內的位移之比為12：22：32……n2
② 在第1s 內、第 2s內、第3s內……第ns內的位移之比為1：3：5……(2n-1)
③
在第1m 內、第2m內、第3m內……第n m內的時間之比為1：
：（
……(
(5) 初速無論是否為零,勻變速直線運動的質點,在連續相鄰的相等的時間間隔內的位移之差為一常數：Ds = aT2 (a：勻變速直線運動的加速度 T：每個時間間隔的時間)
9、勻速圓周運動公式
線速度：v= wR=
f
向心加速度：a =
2 f2
R
角速度：w=
向心力：F= ma = m
2 R= m
4
m f2 R
注意：（1）勻速圓周運動的物體的向心力就是物體所受的合外力，總是指向圓心。
（2）衛星繞地球、行星繞太陽作勻速圓周運動的向心力由萬有引力提供。
（3）氫原子核外電子繞核作勻速圓周運動的向心力是原子核對核外電子的庫侖力。
10、平拋運動公式：水平方向的勻速直線運動和豎直方向的初速度為零的勻加速直線運動（即自由落體運動）的合運動
水平分運動： 水平位移： x= vo t 水平分速度：vx = vo
豎直分運動： 豎直位移： y =
g t2 豎直分速度：vy= g t
tgq = 
vy = votgq vo =vyctgq
v = 
vo = vcosq
vy = vsinq
11、 功 ： W = Fs cosα (適用于恒力的功的計算）
（1）力F的功只與F、s、α三者有關，與物體做什么運動無關
（2）理解正功、零功、負功
（3）功是能量轉化的量度
12、 動能和勢能： 動能： 
重力勢能：Ep =
mgh (與零勢能面的選擇有關)
13、動能定理：外力對物體所做的總功等于物體動能的變化。
公式： W合= DEk = Ek2
- Ek1 = 
14、機械能守恒定律：機械能 = 動能+重力勢能+彈性勢能
條件：系統只有內部的重力或彈力（指彈簧的彈力）做功。
公式： mgh1 +
15、功率： P = 
(在t時間內力對物體做功的平均功率)
P = Fv (F為牽引力，不是合外力；v為即時速度時，P為即時功率；v為平均速度時，P為平均功率； P一定時，F與v成反比）
16、功能原理：外力和“其它”內力做功的代數和等于系統機械能的變化
17、功能關系：功是能量變化的量度。
摩擦力乘以相對滑動的路程等于系統失去的機械能，等于摩擦產生的熱 
18、物體的動量 P=mv,
19、恒力的沖量 I=Ft
20、動量定理: Ft=mv2―mv1
21、動量守恒定律 
+m2v2 =
m1v1’＋m2v2’ 或Dp1 = - Dp2 或Dp1 +Dp2=0
適用條件：（1）系統不受外力作用。（2）系統受外力作用，但合外力為零。（3）系統受外力作用，合外力也不為零，但合外力遠小于物體間的相互作用力。（4）系統在某一個方向的合外力為零，在這個方向的動量守恒。
完全非彈性碰撞 mV1+MV2=（M+m）V
22、簡諧振動的回復力 F=－kx 
加速度
23、單擺振動周期 
(與擺球質量、振幅無關）
24、彈簧振子周期 
共振：驅動力的頻率等于物體的固有頻率時，物體的振幅最大
25、機械波：機械振動在介質中傳播形成機械波。它是傳遞能量的一種方式。
產生條件：要有波源和介質。
波的分類：①橫波：質點振動方向與波的傳播方向垂直，有波峰和波谷。
②縱波，質點振動方向與波的傳播方向在同一直線上。有密部和疏部。
波長λ：兩個相鄰的在振動過程中對平衡位置的位移總是相等的質點間的距離。
注意：①橫波中兩個相鄰波峰或波谷問距離等于一個波長。
②波在一個周期時間里傳播的距離等于一個波長。
波速：波在介質中傳播的速度。機械波的傳播速度由介質決定。
波速v波長λ頻率f關系：
（適用于一切波）
注意：波的頻率即是波源的振動頻率，與介質無關。

在LC回路中，當振蕩電流為零時，則電容器開始放電, 電容器的電量將減少, 電容器中的電場能達到最大, 磁場能為零。
