On sunny summer days, everything gets hot. When you sit on a bike seat...Ouch! Luckily, in many places, bike seats are now wearing silver “coats” to keep cool.
Bicycle seats can get hot in the sun easily. When the air temperature is33℃, the temperature of seats in the sun can achieve67.8℃. This temperature is much higher than that of human skin.
Even with clothes on, touching these seats can hurt our skin. Riding for a long time may put you at the risk of getting low−temperature burns.
However, the temperature of the silver seat in the hot sun is only42℃ to45℃. Its silver colour takes in much less heat than black, the common bike seat colour. And it is made from special materials. The materials can send more of the heat away. So the seat stays cool.
Other “cool” things
· Mint(薄荷)
Mint has something special inside called menthol(薄荷醇). This menthol makes your nerves (神经)feel cool, even if the temperature stays the same. When you eat mint or put it on your skin, it can make you feel cooler.
· Cooling patch(清凉贴)
A cooling patch has gel(凝胶) and water in it. The gel takes in the heat from your body. This makes you feel more comfortable.
· Cooling spray(清凉喷雾)
A cooling spray sends out very small water drops. They can take in the heat from your skin.

本文主要介绍了自行车座椅银色“外套”的作用以及其他三种让你自己保持“凉爽”的东西。
1. B 细节理解题。根据第一段中的“Luckily, in many places, bike seats are now wearing silver ‘coats’ to keep cool.”可知，设计师们设计自行车座椅的银色“外套”的目的是让它们在阳光下保持凉爽。
2. B 词义猜测题。句意：当空气温度为33℃时，太阳光下座椅的温度可达到67.8℃。根据句意理解可知，此处动词achieve的意思是“达到，到达”，跟动词reach的意思相接近。
3. A 推理判断题。根据第二段中的“When the air temperature is 33℃, the temperature of seats in the sun can achieve 67.8℃.”可知，此段回答了自行车座椅在阳光下能有多热的问题。
4. D 推理判断题。根据“Cooling patch”中的“The gel takes in the heat from your body.”可知，这种凝胶从身体中吸收热量，并不是给你的身体补充更多的水。
5. A 标题概括题。通读全文内容可知，本文介绍了在炎热的夏天给自行车座椅穿上银色“外套”来保持凉爽，同时阐述了这种“清凉坐垫”的工作原理，另外文中还介绍了薄荷、清凉贴和清凉喷雾这三种让人感觉凉爽的东西，故A项最为恰当。
