题目内容

有一批食品罐头，标准质量为每听454 g，现抽取10听样品进行检测，结果如下表(单位：g)：

这10听罐头的总质量是多少？

答案：
解析：

　　解：把超过标准质量的克数用正数表示．不足标准质量的克数用负数表示，列出10听罐头的质量与标准质量的差值表如下：(单位：g)：

　　这10听罐头的质量与标准质量的差值和为：

　　(－10)＋5＋0＋5＋0＋0＋(－5)＋0＋5＋10＝[(－10)＋10]＋[(－5)＋5]＋(5＋5)＝10(g)．

　　因此，这10听罐头的总质量为454×10＋10＝4 550(g)．


提示：

　　当已知的一列数中和数都比较大，但都与某一个数比较接近时，一般就以这“某一个数”为基数，超过的记为正，不足的记为负，这样计算起来比较快捷、简便．

Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees arc competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition “depending on who needs it”.

Nitrogen（氮） and carbon are shared through miles of underground fungi（真菌） networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons（神经元）in our brains, and when one tree is destroyed, it affects all.

Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.

“We didn’t take any notice of it.” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

4.What would be the best title for the passage?

B. Young Trees Are In Need Of Protection

C. Trees Are More Awesome Thart You Think

Robert Moody, 52, is an experienced police officer. Much of his work involves dealing with drugs and gang problems in the schools of his community. Knowing that many kids often ______trouble, he decided to do something about it. So in 1991 he began to invite small groups of kids to go fishing with him on his day off.

Those fun trips had a______impact. A chance encounter in 2000 proved that. One day, while working security at a school basketball game, Moody noticed two young guys _______. He sensed trouble between them. _____, one of them headed toward Moody and gave him a hug. “I remember you. You took me ______ when I was in fifth grade. That was one of the ______days of my life.”

Deeply touched by the boy’s words, Moody decided to create a foundation that ____ teenagers to the basis of fishing in camping programs. “As a policeman, I saw where there was violence, drugs were always behind it. They have a damage ______ on the kids,” says Moody.

By turning kids on to fishing, he intended to present an alternative way of life, “When you are sitting there waiting for a _______” he says, “you can’t help but talk to each other, and such conversation can be very deep.”

“Talking about drugs helped prepare me for the peer(同龄人) pressures in high school ,”says Michelle, 17, who _______ the first program. “And I was able to help my little brother _______ drugs”

Moody faces retirement in three years, when he hopes to run the foundation full-time. “I’m living a happy life and I have a responsibility to my_____to give back,” Moody says. “If I teach a kid to fish today, he can teach his brother to fish tomorrow.”

Life on earth depends on water, and there is no substitute for it. The current assumption is that our basic needs for water — whether for drinking, agriculture, industry or the raising of fish will always have to be met. Given that premise（前提）, there are two basic routes we can go: more access to water or more engineering solutions (more dams, for instance).

Looking at the engineering solution first, a lot of my research concentrates on what happens to wetlands when you build dams in river basins, particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal regime of the river, or rather, the pulse of the water. And the fact is that if you build a dam, you generally spoil the downstream ecology. In the past, such problems have been hidden by a lack of information. But in the next century, governments will have no excuse for their ignorance. The engineers ability to control water flows has created new kinds of unpredictability. Dams in Africa have meant fewer fish, less grazing and less agriculture — none of which were expected.

The challenge for the next century is to find new means of controlling water. Although GM technology will allow us to breed better dry-land crops, there is no market stimulation for companies to develop crops suitable for the micro-climates of the Sahel and elsewhere in Africa. Who is going to pay for research on locally appropriate crops in the Third World?

This brings us to the key issue in any discussion of water: money. In the next century, just consider the problems of water supply in Mexico City or Delhi. If you’re rich, you drink mineral water and may even have a swimming pool — yet millions in such cities can’t get safe drinking water. People talk about the coming water crisis. I believe we have one now. It is a water crisis for the poor.

1. According to the passage, what are the two ways to solve the problem of water crisis? (no more than 8 words) (2 marks)

 

2. What will happen when dams are built in river basins in Africa? (no more than 6 words) (3marks)

 

3.Why are companies not willing to develop locally appropriate crops for Third World? (no more than 6 words) (3 marks)

 

4.What is the tone of the passage? (no more than 1 words) (2 marks)

In the 1950s，a family who owned a farm near Beulah，Michigan kept a bull chained to an elm (榆树)．The bull paced around the tree，dragging the heavy iron chain，which led to a groove (槽) in the bark.The groove deepened over the years，though for whatever reason，it did not kill the tree.

After some years，the family took their bull away.They cut the chain，leaving the loop (圈) around the tree and one link hanging down.

Then one year，agricultural disaster struck Michigan in the form of Dutch Elm Disease.All of the elms lining the road leading to the farm became infected and died.Everyone thought that the old elm would be next.

The farm’s owners considered doing the safe thing：pulling it out and cutting it up into firewood before it died.But they simply could not bring themselves to do it.It was as if the old tree had become a family friend.So they decided to let_nature_take_its_course.

Amazingly，the tree did not die.Nobody could understand why it was the only elm that was still standing in the country!

Plant pathologists(病理学家) from Michigan State University came out to observe the tree.They observed the scar left by the iron chain，now almost completely covered by bark.The plant experts decided that it was the chain that saved the elm’s life.They reasoned that the tree must have absorbed so much iron from the chain that it became immune (免疫) to the fungus (真菌)．

It’s said that what doesn’t kill you will make you stronger.Or，as Ernest Hemimgway put it，“Life breaks us all，but afterwards，many of us are strongest at the broken places.”

A．The elms were tied by iron chains.

B．Some of the elms were cut up into firewood.

D．Nearly all of the elms died of a disease.

2.From the passage we can learn that the old elm was saved by________.

A．the groove in the bark B．the fungus in the tree

C．the iron remaining in it D．its own immune system

3.The underlined sentence “let_nature_take_its_course” means______.

A．leave the elm at the mercy of nature

B．help the elm grow normally

C．let nature take the elm away

D．have nature give a lesson to the elm

4.What is the best title for the text?

A．Never Lose Heart in Trouble

B．Strike While the Iron is Hot

C．Brave to Face Failure

D．Stronger after Suffering
