Passage Five
A wind tunnel is used for testing planes or plane models.In a wind tunnel air is blown over a plane ora model placed in a test section.Wind tunnel test sections are different in size depending on airflow speed requirements.Some low-speed tunnels have test sections large enough for a complete small plane.In the very high speed tunnels used for space testing，however，the model may be as small as a pencil.
There are two ways of feeding air to the test section.In the constant flow tunnel，airflow produced by electric fans is forced through the tunnel to the test section，then through another tunnel section back to the starting point for reuse.The other way involves storing high-pressure air in a box，sending it out by a controlling device to pass through the tunnel and test section into another box.This way is usually used for a very short period of high-speed airflow.
Wind tunnels are usually used to test planes before they are flown.Problems in a plane carl be found when it meets the high-speed airflow in the tunnel.For example，if the wings are built so that they would weaken at high speeds，this fact can be discovered in the tunnel，thus saving many lives and millions of dollars.
In a wind tunnel，scientists also find out how different planes will act at different speeds.They find out such things as how the air dives by the wing surfaces，how slowly a plane can fly before it starts to drop，and howfastit can climb.
第52題單選 Some wind tunnel sections are larger than others because____.
A.they are used for large planes
B.they can produce a stronger wind
C.they are built to conduct a high-speed test
D.the air in them flows at a lower speed
參考答案：D
參考解析：根據常理，風道面積大，風速就慢。 D是正確答案。
第53題單選 The underlined words“this fact”in Paragraph 3 refer to the fact that____.
A.it costs a lot to test a plane
B.the wings are not good enough
C.some problems are found with a plane
D.the wings meet the high-speed air flow in the tunnel
參考答案：B
參考解析：本句是說如果機翼劣質，高速飛行時會受損。 問題中的this fact 指的是機翼質量不好。故B正確。
第54題單選 As mentioned in the last paragraph，a wind tunnel can be used to find out____.
A.how fast a plane can rise
B.how smooth a plane’s surface is
C.how a plane lands in a strong wind
D.how a plane drops at a low height
參考答案：A
參考解析：這個句子and how fast it can clim B.說明A是正確答案。
第55題單選 What can we learn from the passage?
A.It is very expensive to build a wind tunne
B.Wind tunnels are very essential in testing plane
C.Scientists still have a lot to learn about wind tunnel
D.There are new ways to feed air to the test sectio
參考答案：B
參考解析：文章最后一段說明wind tunnels 在檢測新飛機的性能上是非常重要的。故B正確。
