While throwing open the windows feels natural in hot weather, did you know it may actually be letting hot air into your home and making it even more stuffy(闷热的)? In order to keep their homes as cool as possible, many people are wondering whether it's better to have windows opened or closed. 16
On hot days, your natural instinct may be to throw open the windows to let in the cool air. 17 The rule you should go by is whether it is hotter outside than inside. If the temperature is higher outside than it is inside, you should keep your windows and curtains closed. This will shut the heat out, and help to keep your home cool. If, however, it's cooler outside or there's a pleasant breeze(微风), then you should open the windows.
You may want to leave them open during the night, when it is most likely cooler outside than inside, but you'll want to close them as soon as it starts heating up. 18 Remember to close them as it reaches the hottest part of the day.
The easiest way of knowing when is best to shut the windows is by having a thermometer(温度计) inside and outside, and act accordingly depending on the reading. 19 Close your curtains as the sun hits that part of your house—even if the windows are open. Use light - colored curtains and keep them closed.
20 This means keeping interior doors open, so the cold air is pushed through different rooms.
Looking for other ways to stay cool during the heat wave? Consider buying a fan so you don't need to rely on opening the windows too much.
A. Here's what you need to do.
B. But this may actually be making your home even hotter.
C. It's also a good idea to avoid direct sunlight getting inside.
D. Keep rooms cool by using reflective material outside the windows.
E. You could leave windows open in the morning and in the evening.
F. You should always consider home safety and security when leaving windows open.
G. While the windows are open, you should make sure that air can circulate around your house.

答案： 16. A 上一句提到，很多人都想知道窗户是开着好还是关着好，下文则介绍了什么时候应该开窗户、什么时候应该关窗户，故 A 项“这是你需要做的”承上启下，符合语境。
17. B 上一句提到在炎热的天气里，你的本能反应可能是打开窗户让凉爽的空气进来，下一句则提出你应该遵守的规则是室外是否比室内热，由此可知，空处应是反对天热就开窗的行为，故 B 项“但这可能会让你的家变得更热”符合语境。
18. E 上一句提到你可能在晚上凉爽的时候开窗，在开始热的时候关上。E 项“你可以在早上和晚上让窗户开着”承接上文，指出具体的做法。
19. C 下一句提到当阳光照射到你房子的那一部分时要拉上窗帘，故 C 项“避免阳光直射室内也是一个好主意”引出下文，符合语境。C 项中的 direct sunlight 是关键词，与下一句中的 the sun hits 相呼应。
20. G 下一句提到这意味着要保持室内门开着，这样冷空气就可以通过不同的房间，由此可推知，空处应是告诉我们应保持空气流通。G 项“当窗户开着的时候，你应该确保空气能在房内四处流通”引出下文，符合语境。
