13.Millions of years ago there were many types of dinosaurs on earth.Most dinosaurs were
plant eaters.The Apatosaurus,for example,had a long thin neck so that it could eat leaves from trees.Other dinosaurs were meat eaters.The Tyrannosaurus Rex killed smaller dinosaurs for food.
Dinosaurs were real animals that once lived on the earth,but they died out about 65million years ago.The disappearance of the dinosaurs is in some way a puzzle.Some scientists think that the climate changed suddenly.Fossils of trees tell us that the temperature dropped a lot and that the level of the sea dropped as well.This means that it got suddenly much colder.Perhaps the dinosaurs were too slow to change with the climate.
A new idea is that a meteor crashed into the earth.Scientists discovered a place in Mexico where they think the meteor crashed.They think that there was a lot of dust from the meteor.The dust landed on the plants.Also the dust blocked the sun's light for as long as five year.Many animals,including dinosaurs,were plant eaters,and perhaps the dust killed them.This means there was nothing left for meat eating dinosaurs to eat,and so they died out.But,as many animals from that time didn't die,we are not sure what really happened.
28.Dinosaur probably meansA.
A.恐龍    
B.化石     
C.大象    
D.長(zhǎng)頸鹿
29.What is the subject discussed in the text?C
A.Dinosaurs,the real animals living millions of years ago.
B.The two types of dinosaurs.
C.The probable reasons for dinosaurs'disappearance.
D.A meteor crashed into the earth.
30.What are the two possible explanations to the dinosaurs'disappearance?B
A.Temperature dropping and sea level dropping.
B.Climate changing and meteors crashing.
C.The dropping of temperature and sea level.
D.Climate changing and the dust blocking the sun.
31.What is the real cause of the disappearance of dinosaurs?D
A.A meteor's crashing.
B.The dust blocking the sun.
C.The plant eating dinosaurs'death.
D.It is still unknown.

18.In today's consumer world,we've never had so much,yet it seems we've never been so unsatisfied.The cost of housing has been rising for decades,and the cost to the planet has been huge,too.But there is a way to live a simpler,greener,and more affordable life:buy a TinyDwelling home!
TinyDwelling homes are very small,yet comfortable houses at affordable prices.Each TinyDwelling home has a contemporary design and included a living room,kitchen,bathroom,upstairs sleeping area,and convenient storage space.TinyDwelling homes are cheap to run and ecologically-friendly,too.All you need is a small heater to keep your house warm in cold weather,and solar panels (太陽(yáng)能電池板) in order to provide light and electricity.

Lizzy Morriaon,a small-living enthusiast,started TinyDwelling homes in 2008to meet the needs of these people.Since then,Lizzy has been designing and building homes nonstop,and TnyDwelling homes have become so popular that thousands of people have bought one.And Lizzy hasn't only designing and building houses.She has also been teaching people how to build them.Simply buy the plans and materials so that you can build your own home,and save even more money!
12.It is implied in Paragraph 1thatB.
A.rich people are very unsatisfied
B.people are damaging the environment
C.there are more poor people than before
D.people spend much money in saving the planet
13.What do we know about the small-living movement?D
A.It aimed to handle the economic crisis.
B.It was started by people without houses.
C.It was well received by house designers.
D.It did not become quite popular until 2008.

A.They are affordable.
B.They provide storage space.
C.They have upstairs sleeping area.
D.They are equipped with solar panels.
15.Besides designing TinyDwelling homes,Lizzy alsoB.
