We sometimes call the lion “the king of the jungle (叢林)” because it is stronger and more dangerous than other animals. It can run faster than many animals and it can hunt (捕獵) the best. It is the highest animal in the   1  food chain (食物鏈).

In the sea, the shark is one of the animals at the  2  of the food chain. It can swim faster than most other sea animals, and it can use its big teeth to eat them.

What is at the top of the world’s food chain?  3  are! We are not the biggest or fastest, but we are the   4  We could not run faster than cheetahs (獵豹),  so we  5  cars and now we can move the fastest. We could not  6   better than lions, so we invented guns (槍). Now we can hunt the best.

Dirty rivers kill fish.  Then bears cannot eat the fish and the bears die. If we kill one part of the food chain,   9   also die. Remember that we are a part of the food chain, so we are in danger too! If we protect animals, we are protecting   10  ! We should and we could do something for the world!

Psychology(心理學)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(渴望的) 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 nature provides us with the desire to experiment and take chances.
Risk taking is a great advantage that allowed our ancestors(祖先) to become stronger and stronger day by day. By taking risks they fought off enemies and discovered new territories(領(lǐng)土). This attitude has become a part of our modern culture. Riding a roller coaster 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 (生物學的) 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(火箭); 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(獲得) something. It is impossible to move forward in life, earn money, enjoy a relationship, play a sport, or do anything else without taking a risk. It is all part of the game. It’s one of the most important parts of life.
【小題1】Some people don’t want to take risks, mainly because ___________.
A.they are too lazy to move on
B.they feel pleased with the present life
C.they have failed several times before
D.they show little interest in the strange world outside
【小題2】What does the underlined part “This attitude” in Paragraph 3 mean?
A.Taking risksB.Fighting off enemies
C.Discovering new territoriesD.Becoming stronger and stronger
【小題3】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.
【小題4】 Businessmen take a risk in order to __________.
A.sell parts of a company
B.complete many things
C.make more money
D.get inside a rocket
【小題5】What would be the title for the passage?
A.Taking risks is easier said than doneB.Risks taken by ancestors
C.Live our life to the fullestD.No risk, no gain.

When I was growing up, I had an old neighbor, Dr. Gibbs. He didn't look like any doctor I'd ever known. He never invited us to play in his yard, but he was a very kind person. When Dr. Gibbs wasn't saving lives, he was planting trees. He owned a large field and wanted to make it a forest. The good doctor had some interesting ideas about planting trees. He never watered his new trees. Once I asked why. He said that watering plants spoiled(毀壞) them, and that if you watered them, each baby tree would grow weaker and weaker, so you had to make things difficult for them and pick out the weaker trees early on.

He talked about how watering trees made for shallow(淺的) roots(根), and how trees that weren't watered had to grow deep roots in search of water under the earth by themselves. Deep roots were very important. So he never watered his trees. He'd planted an oak(橡樹)and instead of watering it every morning, he'd beat it with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree's attention.

Dr. Gibbs died several years after I left home. Every now and then, I walked by his house and looked at the trees that I watched him plant about twenty-five years ago. They're very big and strong now. I planted some trees a few years back and carried water to them for a whole summer. After two years of caring too much, whenever a cold wind blows in, they shake a lot.

Every night before I go to bed, I check on my two sons. Mostly I pray (祈禱) that their lives will be easy. But lately I've been thinking that it's time to change my prayer. I know my children are going to face difficulties. There's always a cold wind blowing somewhere, so what we need to do is to pray for roots that reach deep into the brave heart, so when the rains fall and the winds blow, we could face it strongly and won't be beaten down.

1. We know from the passage, the doctor______.

A. didn't know how to plant trees at all  

B. wasn't good at his own medical job

C. had his own ways of planting trees   

D. had nothing to do but plant trees

2. When Dr. Gibbs said "... pick out the weaker trees early on.", he meant that______.

A. some weak trees would be easily found out at the beginning

B. he would choose the weak trees to water earlier

C. the weak trees would be sent to his patients later

D. he would not plant weak trees so early anymore

3. The passage tells us that the writer______.

A. should beat his trees with a rolled-up newspaper 

B. didn't often water his trees

C. didn't have a large field                     

D. took too much care of his trees

4.The writer wants to change his prayer, hoping that______.

A. his trees will be stronger than Dr. Gibbs'  

B. his trees will not be beaten down

C. his sons will be better at planting trees    

D. his sons will be able to face difficulties

5.Which can be the best title of the reading?

A. Watering Trees                 B. Growing Roots 

C. Doctor and his Neighbor         D. Father and his Children

科目:初中英語 來源:2010年成都市九年級上學期期中考試英語試題 題型:閱讀理解

We live on the earth. We use the sea around us. What do we take from the ocean? And what do we give to it?

We take fishes from the ocean—millions of kilograms of fish, every year, to feed millions of people.  1.   We take minerals(礦物) from the ocean. We can get salt by evaporating(蒸發(fā)) seawater.  2.    Many other minerals, such as gold, can be also got from the sea, but not by simple evaporation. 3.    Seaweed(海草) 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 can’t drink ocean water.   4.   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? We pollute the ocean all the time.   5.  Throwing waste 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. Hopefully, it is not too late.

 根據(jù)以上內(nèi)容,從下列五個選項中選擇適當?shù)木渥舆原到短文中,使短文完整與正確。將其標號在答題卡上涂黑。(每小題2分,共10分)

A. Other gifts from the sea , such as seaweed, can be also got from the sea.

B. Huge as it is, the ocean can’t hold all that we pour into it.

C. Along with salt, other minerals are left after evaporation.

D. We even use their bones(骨頭) for fertilizer(化肥).

E. Some of its contents(所含物) may cause illness.
