1 . Bees are known to tell time by light and social clues. Now, researchers have shown that the biological clocks of bees can be changed by another surprising factor: temperature cycles inside the hive (蜂巢).
The researchers tried to better understand how bees lived in areas beyond where light entered the hive.They were surprised to find clear temperature fluctuations across the day throughout the hive, which was caused by daylight.
To understand how important this temperature cycle was to a bee's activity, the researchers put bees in total darkness all the time while exposing them to the temperature cycles they observed within the hive. Six days later, the scientists moved the temperature cycle back by six hours. “We saw that the bees changed their activity with the temperature, meaning their daily routines were reactive to temperature,” a researcher said.
The discovery that bees can tell exact time from temperature cycles inside the hive shows that on a cloudy day or when bees aren't going outdoors, they have other means to tell time exactly. This will affect the way that researchers understand, explain and combine what they know of bee behavior.
More broadly, as more extreme weather events occur around the world, bees will face challenges to continuing the activities that keep them and the agriculture they support healthy and energetic. If part of the southern U.S. is hit with an unexpected snowstorm, bees getting ready to search for food might not realize they need to save energy and heat the hive. In the event of a 100-degree day, bees will have to spend a lot of energy keeping the hive co. It is those considerations that will influence hive health or possible hive breakdown.
"We want to see how important this research is this winter in Tennessee，when bees aren't leaving the hive as much," researchers said. "We will be interested to see how our findings apply to zones where temperature varies more greatly across the year." This research will also reshape how researchers think about bees' biological rhythms.

2 . Dealing with school stress is something most students have to learn to do during the course of their education.
Ask for help.
Practice thought-stopping. Sometimes feeling overwhelmed (不知所措) in a stressful situation leads to fast, or “racing” thoughts. If this happens to you, try a way named “thought-stopping”.
| A．Know the source of your stress |
| B．When you have stress, keep an objective attitude |
| C．Get to know the way your body experiences stress |
| D．If you don’t know how to deal with a stressful thing |
| E．They may try their best to help you solve the problem |
| F．However, many students still don’t know how to deal with it |
| G．This means stopping your thoughts and turning your attention to something else for a while |
3 . Do you know what to do when there is an emergency? By calling the police, you can protect yourself and those around you.
Call the police in all of the following emergencies:
◆A crime, such as a theft, especially if it is still in progress.
◆A car accident, especially if someone is injured.
◆Domestic violence (家庭暴力), such as a child being mistreated.
◆Anything else that seems like an emergency.
◆What should you do when you call the police?
◆Dial 110 (the emergency number in China; the number varies from one country to another—in the U. S., you dial 911 to call the police). Stay calm when calling and give your name, address and phone number. Then, tell the person why you are calling (What happened? Where did it happen? When did it happen? Is it still in progress?). Follow any instructions you are given. For example, the dispatcher (调度员) might say, “Stay on the line” or “Leave the building”.
◆If you dial the emergency number by mistake, do not hang up. Doing so could make the dispatcher think an emergency really exists. Instead, just tell the person that you called by mistake. Most police departments have a communication center. The communication center staff reach police officers by radio. Police officers carry headsets, like earphones, to stay in touch with the communication center.
1. When calling the police, you DON’T need to give ________ to the dispatcher.| A．your name | B．your phone number |

4 . The following charities advocate protecting our precious environment. It’s a starting place, but don’t stop here.
Rocky Mountain Institute
Rocky Mountain Institute has made notable achievements in its comparatively short history. In2017, it worked with India’s leadership and government to plan for 100% vehicle electrification(电气化) by 2030. They also provided research that resulted in new U. S. fuel-efficiency standards for trucks, which were expected to cut over one billion tons of CO₂ emissions. Its five-year plan to quicken low-carbon energy transition (转变) was published in early 2018.
Greenpeace Fund
Although Greenpeace solves many environmental problems such as deforestation (滥伐森林) and sustainable food, it has worked to address issues with oceans for decades: plastic pollution, offshore drilling, saving the Arctic, and more. Greenpeace has grown from a small group of activists protesting nuclear testing in 1971 to an international organization with offices in over fifty countries.
Center for Biological Diversity
Founded in 1989, the Center for Biological Diversity uses biological data and legal knowledge to obtain new protections for plants, animals, and their habitats. Its story began with some young students, an ancient tree in Mexico, and a spotted owl’s nest. Its first campaign saved both the tree and the owl. And they continue to grow by expanding territory, staff, and outreach (外展服务).
Sierra Club Foundation
The Sierra Club has been working to protect the environment and its people since 1892. It helped pass the Clean Air and Endangered Species Acts, enabled the creation of many national parks, and worked to move hundreds of coal plants towards clean energy. It also offers environmentally friendly wilderness outings to encourage people to get outdoors. People can take an international trip to study wildlife in Cuba.

| C．They both have founded numerous national parks. |
| D．They both encourage humans to go outing in the wild. |
5 . I was filled with doubts and worries until my grandfather told me to stand tall.
For me, height was my trouble. I was much taller than other girls, so I often bent (弯曲) my body at the back of the line. I had always felt unsafe as the tallest student of my class in Bala Cynwyd. And I wasn’t looking forward to entering the ninth grade.
My grandfather didn’t laugh at me. Instead, whenever I tried to bend myself in order to appear shorter, he would tell me “Stand straight and tall, Alisa”. I trusted my grandfather more than anyone else in my childhood. And whenever I was afraid of something, he always told me stories of his life.
My grandfather grew up in war-torn (战乱的) Europe. “Stand straight, stand tall” meant something else then. After the war, he went to America. He lived a hard life. “If they could do it, why couldn’t I?” “Stand straight, stand tall,” he often reminded himself. Thanks to the help of a friend, my grandfather got a job. He once told me that he was very nervous at first. He was not only trying to learn this hard new job but also a new language.
“Stand straight, stand tall,” he would always tell himself. I am so proud of my grandfather. After listening to my grandfather’s unusual experiences, I have changed the way I look at my own life.
“Stand straight, stand tall” has become not only a piece of advice to improve my posture (身姿). It also tells me to be proud of who I am.
And I do.

9 . Where to Find the Perfect Christmas Tree Around Baltimore This Year
A handful of the area’s best choose-and-cut Christmas tree farms are only a quick road trip away.
A SNOWBALL’S CHANCE TREE FARM
This choose-and-cut Christmas tree farm of 16 acres has been run by a couple since 2005. Open for one weekend only, Dec. 3-4, this year, the new location in Woodstock will offer eight and nine-inch pre-cut Fraser Firs or cut-your-own White Pines & Blue Spruces.
10231 Harvest Fields Drive, Woodstock
DAVIDSON CHRISTMAS TREE FARM
Although it’s been active for more than two centuries, this family-owned Upperco Farm didn’t start to plant Christmas tree seedlings until the late 1960s.

The two have since passed away, but the farm, now operated by Paul Stiffler, has 15acres of ready-to-cut trees ranging from Scotch Pine to White Pine, Douglas Pine, and Norway Spruce. The farm re-opens on the last weekend of November, after Thanksgiving.
8926 Cowenton Ave., Perry Hall
