Imagine growing a home from living trees instead of building a home from wood. Mitchell Joachim, at the MIT Media Lab's Smart Cities Group, along with ecological engineer Lara Greden and architect Javier Arbona, have proposed a system of homes that are actually a living ecosystem.

Joachim's vision is based on a gardening method known as pleaching, which involves weaving branches together to form living lattice(格子) walls. Since the growth patterns of trees are affected by wind and sunlight, it may be possible to manipulate the way a tree develops.

This idea is an extreme, yet simple and beautiful, form of green building. Not only does it not cause direct harm to the environment, but it is actually part of the environment. The house, which is a network of trees, would clean the air and also provide a home for animals and birds. "Not only does it do zero damage, but it will hopefully clean the air," says Joachim.

"A 100 percent treehouse would take years to create," Joachim said. Depending on the climate, a house could take anywhere from 5 to 30 years to grow. Fortunately, there's a way to speed up the process.

Ecological materials, Joachim suggests, should be included in the housing designs. For example, windows can be made from soy-based plastics that would flex (折曲) with the home as it grows.

So what happens when a home and the great outdoors are one and the same? A home would become an actual ecosystem, a community of plants, animals, and bacteria working together. The trees would also give off water vapor that would assist in cooling the homes. Solar panels and wind would help provide energy. Straw and clay could be used to insulate(使绝缘) the structures. The tree homes might even have soil pockets, where plants could grow from the structure itself.

Joachim's project is called MatScape, designing a house in California that will be constructed from 50% recycled and 50% living elements. He sees it as an experimental step toward the final living house.

57.The best title for this passage would be______.

A.Trees Find Its New Use                               B.Scientists Create New Houses

C.Grow Your Home Out of Trees                       D.People Begin Living in Trees

58.The underlined word "manipulate" in Paragraph Two can be best replaced by     .

A.build                      B.influence                C.weave                     D.provide

59.It can be inferred from this passage that__________.

A.treehouses will replace traditional buildings

B.pollution problem will be solved once for all

C.many Californians may be building their own treehouses

D.some ecological materials may move as the house grows

60.If this passage is continued, what would probably be discussed?

A.A final living house.                                          B.Joachim's MatScape project.

C.More information about pleaehing.               D.Some more ecological materials.

请填写下列空白:

(1)用惰性电极电解2 L食盐水时,总反应的离子方程式_______________________________,当阴极上产生224 mL气体(标准状况)时,所得溶液的pH=             (假设电解前后溶液体积不变,食盐水足量)。

(2)写出高温下钛铁矿经氯化得到四氯化钛的化学方程式                             。(提示:FeTiO3中Ti为+4价)

(3)反应2Mg+TiCl42MgCl4+Ti在Ar气氛中进行的理由是____________________。
