Pollution inside homes and other buildings kills more than 4 million people each year.Many people die as a result of breathing smoke or from cooking over wood﹣powered of coal﹣powered stoves.
One way to reduce the number of deaths is through cooking equipment powered by the sun.Crosby Menzies,a solar power expert in a South African company,described his latest solar cooker called the“Sol.4”,”It is four square meters of mirrors,six to eight meters in length.It is quite a large cooler.”
The“Sol.4”works by reflecting (反射)light from the sun off large mirrors.The mirrors direct (把…对准)the light at a cooking pan.Then the light heats the pan with solar energy.Within two minutes,the pan is hot enough to cook sausages and onions.In just four minutes,water can be boiled.That is as fast as cooking with natural gas or electricity.
The cooker is also much “friendlier” than other models because people do not have to stand in the sun to use it.And people can prepare meals without having to collect firewood or spend money on coal.Such individuals would be less likely to have breathing illnesses from harmful smoke.
At present,the cooker only works when the sun is shining.But engineers are working on a way to make it work without sunlight.
Each cooker costs about $2000,which is a large amount of money for most Africans.To solve that problem,Crosby Menzies has crated a non﹣governmental organization called solar Cookers for Africa.It plans to raise money through donations to provide poor people with solar cooking equipment.

Would it surprise you to learn that, like animals, trees can communicate with each other and pass on their wealth to the next generation--their young trees?
Suzanne Simard, forest ecologist at the University of British Columbia, explains how trees are much more complex than most of us ever imagined. Simard and her colleagues have made the major discovery that trees and plants really do communicate and interact with each other.
Trees live on through their group work and support, passing around the resources such as nitrogen and carbon “depending on who needs it by miles of underground fungi(真菌) networks. This makes sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This system works in a very similar way to the networks of neurons(神经元) in our brains, and when one tree is cut down, it affects all.
Simard talks about "Mother Trees". These are the largest, oldest trees that rise above the forest, a concept explained in the movie Avatar. These “Mother Trees" are connected to all the other trees in the forest by this network of fungi, and may manage the resources of the whole trees and plants in the forest. She explains how these trees pass on the wealth to the next generation, transporting important resources to young trees so they may continue to grow. When humans cut down "Mother Trees" without paying attention to these highly complex "tree societies” or the networks on which they feed, we are losing the chances to save the whole forest.
"We didn't take any notice of it,” Simard says sadly. “Mother Trees move nutrition into the young trees before dying, but we never give them a chance.” If we could send this message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

3.The underlined word “it” in the last paragraph refers to________ .
A.how trees grow old B.how "tree societies" work
C.how young trees are saved D.how forestry industry develops
4.What would be the best title for the passage?
A.Trees Are Rich in Resources B.Trees Are Good for Our Society
C.Trees Are in Need of Protection D.Trees Are More Complex Than We Think
A Move to Safety
The Turners sat at the kitchen table. The sun was shining and filled the kitchen with a warm light. It was a perfect day for having a picnic or going surfing. But in the Turners' kitchen, no one seemed to be paying attention to the ______________.
"Okay, girls," said Mrs. Turner. "I can tell by the expressions on your faces that you have a pretty good idea of why we need to have this family _____________." Linda and Kala exchanged looks and slowly nodded.
"Your mom and I have had many talks lately about the possibility of _____________," said Mr. Turner. "We were hoping that it wouldn't come to this, _____________we don't have other choices."
"But Dad," said Kala, "Kilauea has been an active volcano(火山)since 1983! Nothing has happened to us or to our house yet. I think we'll be ______________here."
"But your dad and I care about all the recent warnings giving by the government. Even though we've been safe up to now, there is no way to guarantee(保证)that a larger eruption(喷发)isn't coming up," said Mrs. Turner.
"Mom, this is our ______________. I can't even remember living anywhere else!" Linda said, fighting back tears.
Mrs. Turner put an arm around her daughter's shoulder. "This won't go _____________for any of us," she said. "Dad and I love this house, too. We have so many happy memories here. But we're tired of living with such uncertainty. The most ______________thing in the world to us is that our family stays safe."
Mr. Turner ______________. "Girls, there are other places in Hawaii where we'll feel safer. We'll have to ______________our house, but you know home is wherever we go as a family. We'll make new ______________, and we'll find things to love about our new home."
The girls were quiet for a moment as they considered _______________it would mean to move. "There are so many things I'll ______________here," said Kala quietly.
"We all will," said Mrs. Turner. "But one of the places that your dad and I have looked at is only a few minutes' walk to the beach."
Kala and Linda couldn't help _____________when they heard that. They both spent every spare minute they had surfing. If their parents told them that they could actually live in the water, they would have been perfectly happy.
Mr. Turner walked around to the other side of the table. He put one large hand on each of his daughter's shoulders. "I'm proud of you two," he said. "Thank you for trying to ______________why this is so important to your mom and me."
Linda and Kala smiled. Dad was right: home was wherever the family was.
