her．After she graduated from a special school，her father set up a blind massage parlor（按摩院），named after his daughter．Four years later，he died of a heart attack．Lin Yan was very sad and felt hopeless．But a phone call from the Guide﹣Dog Training Base changed her life．"I am so excited．I want to be more independent．"Lin Yan said．She spent 20days with Sherry at the base and they came good friends．Sherry helped Lin Yan climb stairs，go for walks and cross the roads．Lin said，"I never thought I could cook．But I'm doing it for Sherry now．My life is exciting with Sherry．It's full of joy and hope．She's more than a dog﹣she's a part of my family，and a true friend．"With the help of audio software that can read what's on the screen，Lin Yan started a blog to tell others

massage parlor．64．Lin Yan stayed with Sherry at the base for 20days．65．Sherry can't help Lin Yan cross the roads．．29．（10分）Rubbish is a major kind of environmental pollution．Each person produces about two kilograms of rubbish in our homes a day．And this is only a small part of all the rubbish we produce．We also create waste in industry．Have you wondered what happens to the rubbish？Most of it is buried in landfills or burned．Less than 25% of our waste is recycled．A landfill is carefully designed and it is built into or on top of the ground．Rubbish buried in landfills is cut off from the surroundingenvironment （groundwater，air，rain，etc．）．One problem with landfills is that they cover a lot of land space．If they are not well﹣built，there is a high risk of polluting the land and water．Some people also say that landfills remove materials for ever．As a result，the materials that can be reused are wasted．Burning rubbish in factories is another way to cut out waste．Burning reduces 95% of the waste．And if poisonous materials are removed．and burning is completed at controlled temperatures，it's possible to do so without causing too much pollution．Some factories could even produce electricity from the burning process．Not all of the rubbish can be burned，so we have to separate（分类） it before we burn it．However，separation costs a lot of money．Another problem with burning rubbish is that what is left after burning is poisonous．How to safely deal with it is a continuing problem．Before the mid﹣20th century，landfills were the main way to deal with waste．In the late 20th century，other ways like recyling have been introduced to help reduce global pollution．阅读短文，从 A、B、C、D 四个选项中找出一个正确的选项填空，使短文完整、通顺．66．What is the advantage of burying rubbish in landfills？A．Reducing 95% of the waste．B．Reusing the materials buried in landfills．C．Producing electricity．D．cutting off rubbish from the surrounding environment．67．What does"landfill"mean in
