What We Take From and Give to the Sea
As long as we have been on earth,we have used the sea around us.We take things from the ocean,and we give to it.
We take fishes from the ocean-millions of kilograms of fish,every year,to feed millions of people.______(46)We take minerals from the ocean.One way to get salt is to place seawater in a shallow basin and leave it until it evaporates.______(47) Much gold and silver drift dissolved in the waters of the sea,too.But the sea does not give them up by simple evaporation.
Other gifts from the sea are pearls,sponges and seaweed.Pearls become jewelry.______(48)
Seaweed becomes food of many kinds-even candy,and ice cream-as well as medicine.Believe it or not,fresh water is another gift from the sea.We cannot drink ocean water.______(49)
But ocean water becomes fresh water when the salts are removed.In the future,we will find ourselves depending more and more on fresh water from the sea.
The sea gives us food,fertilizer,minerals,water,and other gifts .What do we give the sea?
Garbage.______(50)Huge as it is,the ocean cannot hold all the water we pour into it. Dumping garbage into the ocean is killing off sea life.Yet as the world population grows,we may need the sea and its gifts more than ever.
We are finally learning that if we destroy our sea,we might also destroy ourselves.Hopeful-ly,it is not too late.

参考答案
参考解析
解析：前面一句讲到：我们从大海里捕捞大量的鱼供人们食用，接着应讲“甚至连鱼的骨头也被用来做化肥”。even清楚地提示了这两句话的关系。
前面一句讲到：我们可以通过水的蒸发从海水中得到盐。通过常识可知，除了盐之外，水蒸发以后还会有别的矿物质留下来。
前面的内容讲到：除了矿物质外，大海还给了我们珍珠、海绵和海草。接着作者分别用一句话来说明每一样东西的用途。先讲了珍珠，最后讲的是海草，中间的一句肯定是讲海绵的用途了。
前一句话说海水不能喝，接下来很自然要解释为什么不能喝。
前面用garbage有力地回答了“我们给了大海什么”，这里是对回答的具体解释。

BThe world is not only hungry，it is also thirsty for water． this may seem strange to you，since nearly 75% of the earth is covered with water． But about 97% of this water is sea water．Man can only drink and use the other 3% fresh water that comes from rivers，lakes，under-ground and other places． And we cannot even use all of that，because some of this fresh water has been made dirty．At the moment，this small amount(数量) of fresh water is still enough for us． However，our need for water is getting greater and greater． Only if we take steps to solve this problem now，we can get away from a serious world water shortage later on． The people of the world cannot have an enjoyable life without enough clean water．On one hand we should stop wasting this little water of ours，on the other hand we should find ways to reuse it，but this has not been done widely．Today，in most large cities，water is used only once and it then returns to the sea or runs into underground places．lf we can make it clean again，it can be used once more just as if it were fresh from a spring．But even if large cities reuse its water，we still would not have enough in the future． Where．could we turn to next for water?

Psychology tells us that many people hate to take risks. But it is good for us to take risks, especially when the risk is to achieve a desired result. In that way, we become stronger and braver.
Our human nature should be to take risks, but some people just sit and wish they didn't have the fear to move on. This is because they failed a few times in their lives. Please step out and don't let the past hold you back from living life to the fullest. Move forward and move on! In studying the psychology of taking risks, we find that human provides us with the desire to experiment and take chances.
Risk taking is a great advantage that allowed our ancestors to become stronger and stronger day by day. By taking risks they fought off enemies and discovered new territories. This attitude has become a part of our modem culture. Riding a roller caster is a common risk taking activity. Even each person seems to enjoy the risk although they have the understanding that it is dangerous. This psychological and biological connection creates an interesting connection between what is unsafe and what humans enjoy.
Getting in a car each day is a risk. Getting out of bed is a risk, too. We need to take risks so that we can complete many things. Astronauts take risks when they get inside a rocket; however,the things they achieve are great. Businessmen take a risk when they buy parts of a company, however, without doing that, they could not make more money.
We need to take risks so that we can gain something. It is impossible to move forward in life, earn money, enjoy a relationship, play a sport, or doing anything else without taking a risk. It is all part of the game. It' s one of the most important parts of life.
What can we infer from the passage?A.Daily life is full of risks.
B.The safest place has the greatest risk.
C.People should take risks when they are young.
D.We can always achieve our goals by taking risks.

Weight on and off the Earth We are so used to.our life on the surface of the earth that it can be quite an effort for our mind to break free of all the ideas that we take for granted.Because we can feel that things are heavy,we think of "weight"as being a fixed quality in an object,but it is not really fixed at all.If you could take a one-pound packet of butter 4,000 miles out from the earth,it would weigh only a quarter of a pound. Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space?The reason is this:all objects have a natural attraction for all other objects;this is called gravitational attraction.But this power of attraction between two obects gets weaker as they get farther apart.When the butter was at the surface of the earth,it was 4,000 miles from the center.When we took the butter 4,000 miles out,it was 8,000 miles from the center,which is twice the distance.If you double the distance between two objects,their gravitational attraction decreases two times two.If you treble the distance, it gets nine times weaker(three times three)and so on. So this is one of the first things we need to remember that the weight of an object in space is not the same as its weight on the surface of the earth. What about the weight of our pound of butter on the surface of the moon?At the distance the puii of the earth is about 4,000 times smaller than it is here on the surface,so we can forget all about the earth-pull on our butter. On the other hand,on the moon there will be an attraction between the butter and the moon,but the butter will weigh only about one-sixth as much as it does on the earth.This is because the moon is so much smaller than the earth.The amount of gravitational pull that a body produces depends on the amount of material in it.A packet of butter has a gravitational pull of its own;but this is very small in relation to the pull of something as large as the moon,or the earth,or the sun.According to the passage,"weight"should be understood in the sense thatA:it is fixed if it is outside the earth's gravitational puliB:it decreases four times when it is 4,000 miles from the earth's centerC:it varies with the change of the gravitational attraction between two objectsD:things increase in amount as they are closer to the earth's surface

The water we drink and use is running short in the world.We all have to learn how to stop wasting our limited water.One of the steps we should take is to find ways of reusing it.Experiments have already been done in this field.
Today in most large cities,fresh water is used only once,then it runs into waste system.But it is possible to pipe the used water to a purifying factory.There it can be filtered and treated with chemicals so that it can be used again,just as it were fresh from a spring.
But even if every large city purified and reused its water,we still would not have enough.Then we could turn to the oceans.All we’d have to do to make use of the seawater on earth is to get rid of the salt.This process is called desalinization,and it is already in use in many parts of the world.
The way to stop wasting our limited water is to________.A.do experiments with water
B.purify the used water and reuse it
C.use fresh water once again
D.make use of seawater

问答题Practice 9 Four score and seven years ago our fathers brought forth on this continent a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war testing whether that nation or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But, in a larger sense, we can not dedicate we can not consecrate we can not hallow — this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us — that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion— that we here highly resolve that these dead shall not have died in vain — that this nation, under God, shall have a new birth of freedom — and that government of the people, by the people, for the people, shall not perish from the earth.
