2010年理工阅读理解没有这两篇吧：第二篇 Citizen Scientists
Understanding how nature responds to climate change will require monitoring key life cycleevent-flowering，the appearance of leaves，the first frog calls of the spring all around the world．
But ecologists can't be everywhere so they're turning to non-scientists，sometimes called citizen scientists，for help．
CIimate scientists are not present everywhere．Because there are so many places in the worldand not enough scientists to observe all of them，they're asking for your help in observing signs ofclimate change across the world．The citizen scientist movement encourages ordinary people too bserve a very specific research interest-birds，trees，flowers budding，etc．and send their observationsto a giant database to be observed by professional scientists．This helps a small number of scientiststrack a large amount of data that they would never be able to gather on their own．Much like citizenjournalists helping large publications cover a hyper-local beat，citizen scientists are ready for theconditions where thev live． All that's needed to become one is a few minutes each day or each weekto gather data and send it in．
A group of scientists and educators launched an organization last year called the National Phenology Network．"Phenology"is what scientists call the study of the timing of events in nature.
One of the group's first efforts relies on scientists and non-scientists alike to collect data about plant flowering and leafing every year．The program，called Projeet BudBurst，collects life cycle da. ta on a variety of common plants from across the United States．People participating in the projectwhich is open to everyone record their observations on the Project BudBurst website．
"People don't have to be plant experts，they just have to look around and see what's in their neighborhood，"says Jennifer Schwartz，an education consultant with the project．"As we collectthis data．we'll be able to make an estimate of how plants and communities of plants and animals will respond as the climate changes．"
36．Ecologists turn to non-scientist citizens for help because they need them__________________．
A．to provide their personal life cycles
B．to observe the life cycle of plants
C．to collect data of the life cycle of living things
D．to teach children knowledge about climate change
37．What are citizen scientists asked to do?
A．To develop a specific research interest and become professional scientists．
B．To send their research observations to a professional database．
C．To increase their knowledge about climate change．
D．To keep a record of their research observations．
38．In"All that，s needed to become one…(paragraph2)"，what does the word"one"stands for?
A．a citizen journalist
B．a citizen scientist
39．What is NOT true of Project BudBurst?
A．Only experts can participate in it．
B．Everybody can participate in it．
C．It collects life cycle data on a variety of common plants．
D．It has its own website．
40．What is the final purpose of Project BudBurst?
A．To study when plants will have their first buds．
B．To find out the types of plants in the neighborhood．
C．To collect life cycle data on a variety of common plants from across the United States．
D．To investigate how plants and animals will respond as the climate changes．
Rockets in the Sky
If someone asked you．"What color is the sky?"I expect that you would answer，"Blue．"I amafraid that you would be wrong．The sky has no color．When we see blue，we are looking at bluesunlight．The sunlight is shining on little bits of dust in the air．
We know that there is air all around the world．We could not breathe without air．Airplanescoutd not fly without air．They need air to lift their wings．Airplanes cannot fly very high because asthey go higher the air gets thinner．If we go far enough away from the earth，we find there is no air. What is the sky?The sky is space．In this space there is nothing except the sun，the moon andall the stars．
Scientists have always wanted to know more about the other worlds in the space．They havelooked at them through telescopes and in this way they have found out a great deal．
The moon is about 384．000 kilometers away from the earth．An airplane cannot fly to the moonbut there is a thing that can fly even when there is no air．This is rocket．
I am sure that you are asking．"How does a rocket fly?"If you want to know，get a balloon andthen blow it up until it is quite big．Do not tie up the neck of the balloon．Let go!The balloon willfly off through the air very quickly．The air inside the balloon tries to get out．It rushes out through neck 0f the ballOOfl and this pushes the balloon through the air．It does not need wings like an air. plane．
This is how a rocket works．It is not made of rubber like a balloon，of course．It is made ofmetal．The metal must not be heavy but it must be very strong．There is gas inside the rocket whichis made very hot．When it rushes out of the end of the rocket，the rocket is pushed up into the air．
Rockets can fly far out into space．Rockets with men inside them have already reached themoon．Several rockets，without men inside them，have been sent to other worlds much farther away．
One day rockets may be able to go anywhere in the space．
41．What color is the sky?
A．It iS blue． B．It iS white．
C．It is grey．D．It has no color．
42．When an airplane flies too high，___________.
A．the air will be too thin to support its wings．
B．the air will become thicker．
C．the air will exert pressure on it．
D．the air will disappear in no time．
4 3．A rocket can fly to the moon because__________
A．it looks like a balloon．
B．it is much lighter than an airplane．
C．it doesn't have wings．
D．it works like an untied balloon．
44．Which of the following statements about a rocket is NOT true?
A．It can fly when there is no air．
B．It can fly without wings．
C．It is made of strong metal．
D．It is propelled by burning gas inside it．
45．A rocket is pushed up into the air when__________
A．hot gas rushes out of its head．
B．it is powered by gas．
C．hot gas rushes out of its bottom．
D．hot gas rushes out of its neck．
