Battery Park's employee Gary Gaddist discovered the note when he started his work in the morning．He turned to the management office with the note．Later he gave Danielle a call and explained the whole story，“I had to go to the management office of Battery Park，and when I got there I showed the guys the note．They told me if I wanted to look for a needle in a haystack (干草堆)，go ahead．” However，after that，Gary began to do what he thought was worth doing．

Ⅳ．阅读七选五
40% women experience hair loss．_________ Here are 5 common reasons why women experience hair loss and how to prevent it．
A surge in stress
Hair loss is caused by physical or emotional stress and the condition can lead to loss up to 300 hairs a day．Commonly，do not style hair in a way to provide additional stress．Prevent scratching the scalp (头皮) or excessively brushing the hair．Moreover，joining in activities that work to reduce stress can also work to reduce the symptoms．
1
Recovering from dieases
1 in 5 dieases survivors report that they have suffered hair loss throughout recovery．_________ Taking time to reduce levels of stress will work to ease the hair damage over time．In the meantime，reduce the amount of times you brush the hair and the products that may cause dryness．
2
A change in hormones
_________ Hair loss throughout the menopause (更年期) can occur along with common symptoms．Adopting a low fat，balanced diet can work to reduce the risk of hair loss throughout menopause．Sources of fatty acids work to keep hair healthy and keeping levels of stress low can protect hair loss．
3
A deficiency in Vitamin D
Vitamin D in the skin is metabolised (新陈代谢) by a protein that aids in keeping hair thick and reducing damage．If you are experiencing hair loss as the result of Vitamin D deficiency，then it's important to gain a formal diagnosis to benefit from treatment．_________
4
Shifts in weather
Extreme weather doesn't directly result in hair loss．_________ They can lead the sufferer to frequently scratch their scalp，increasing the risk of the hair damage and therefore thinning．There are several treatment shampoos that can work to decrease its symptoms and therefore control the risk of hair damage．Keeping the scalp hydrated is vital．
5
A．Cold weather is also a common factor．
B．However，it may worsen symptoms．
C．Hormonal changes can contribute to hair loss．
D．Lack of Vitamin D may not facilitate hair growth．
E．Temporary hair loss commonly occurs after flu and fever．
F．Internal and external factors play a role in female hair loss．
G．Treatment can't be described as simple as taking Vitamin D tablets．
【语篇解读】 本文是一篇说明文。文章主要介绍了女性脱发的五个常见原因以及如何预防脱发。
1．F [根据上句“40% women experience hair loss．”和下文“Here are 5 common reasons why women experience hair loss and how to prevent it．”可知设空处应为脱发的原因，F项：Internal and external factors play a role in female hair loss．(女性脱发的原因有内因和外因。)符合题意。故选F。]
2．E [根据上句“1 in 5 dieases survivors report that they have suffered hair loss throughout recovery．”可知，设空处对这一现象做出总结，E项：Temporary hair loss commonly occurs after flu and fever．(暂时性脱发通常发生在流感和发烧之后。)符合题意。故选E。]
3．C [根据本段的小标题“A change in hormones”可知，设空处承接小标题说明荷尔蒙的变化对脱发的影响，C项：Hormonal changes can contribute to hair loss．(荷尔蒙的变化会导致脱发。)符合题意，故选C。]
4．G [根据上句“If you are experiencing hair loss as the result of Vitamin D deficiency，then it's important to gain a formal diagnosis to benefit from treatment．”可知设空处要讲到进行正式治疗的相关内容，G项：Treatment can't be described as simple as taking Vitamin D tablets．(治疗不能描述为像服用维生素D片那么简单。)承接上句，符合题意。故选G。]
5．B [根据上句“Extreme weather doesn't directly result in hair loss．”推知，设空处应为极端天气对于脱发的影响，B项：However，it may worsen symptoms．(然而，它可能会加重症状。)符合题意，it指代上文extreme weather。故选B。]

40% women experience hair loss． 1 Here are 5 common reasons why women experience hair loss and how to prevent it．
A surge in stress
Hair loss is caused by physical or emotional stress and the condition can lead to loss up to 300 hairs a day．Commonly,do not style hair in a way to provide additional stress．Prevent scratching the scalp (头皮) or excessively brushing the hair．Moreover,joining in activities that work to reduce stress can also work to reduce the symptoms．
Recovering from dieases
1 in 5 dieases survivors report that they have suffered hair loss throughout recovery． 2 Taking time to reduce levels of stress will work to ease the hair damage over time．In the meantime,reduce the amount of times you brush the hair and the products that may cause dryness．
A change in hormones
3 Hair loss throughout the menopause (更年期) can occur along with common symptoms．Adopting a low fat,balanced diet can work to reduce the risk of hair loss throughout menopause．Sources of fatty acids work to keep hair healthy and keeping levels of stress low can protect hair loss．
A deficiency in Vitamin D
Vitamin D in the skin is metabolised (新陈代谢) by a protein that aids in keeping hair thick and reducing damage．If you are experiencing hair loss as the result of Vitamin D deficiency,then it's important to gain a formal diagnosis to benefit from treatment． 4
Shifts in weather
Extreme weather doesn't directly result in hair loss． 5 They can lead the sufferer to frequently scratch their scalp,increasing the risk of the hair damage and therefore thinning．There are several treatment shampoos that can work to decrease its symptoms and therefore control the risk of hair damage．Keeping the scalp hydrated is vital．
A．Cold weather is also a common factor．
B．However,it may worsen symptoms．
C．Hormonal changes can contribute to hair loss．
D．Lack of Vitamin D may not facilitate hair growth．
E．Temporary hair loss commonly occurs after flu and fever．
F．Internal and external factors play a role in female hair loss．
G．Treatment can't be described as simple as taking Vitamin D tablets．
