A mother goat is able to pick out her own baby from its voice alone by the time the kid is just five days old.
Researchers from University of London played kids’ bleats to female goats and studied their responses. They were surprised to find that the animals were able to pick out their own kids’ voices.
“A mother and the kid rely a lot on smell to recognize one another and, in the wild, during the first week of their lives, the animals hide in grass and don’t call much. It’s a strategy they use to avoid enemies,” Dr Elodie Briefer, who led the research, explained to BBC News. “The mother call to the kids when she want them to come and feed, so we expected that kids would recognize the mothers’ voices.” In fact, this was the case for deer, which also use this hiding strategy, although they do not belong to the same family of species as goats.
She and her team recorded and played back young kids’ calls to the female goats and recorded their responses.She explained, “Even when the calls came from kids that are five to six days old, we could see the mothers responding more to the voices of their own babies.” Hearing the voice of their own kids, the females would look towards the speaker that the sound was coming from, moving around and calling in response.
The scientists say that understanding how goats behave and communicate is very important. “This helps us understand just how smart these animals are,” said Dr. Briefer. “Farmers might be able to change their way to raise goats considering this natural behaviour.”

It’s quite a time for the strange weather, and it does not get much stranger than snow falling in one of the hottest places in the world.
On Sunday morning, Ain Sefra, a desert town in Algeria known as the “Gateway to the Sahara”, experienced a large amount of snow for reportedly the third time in 40 years. Some reports said parts of the area got as deep as 15 inches of snow, but Ain Sefra officially reported less than one inch in some places. Some people were very excited about it. It was strange enough to provide some very special pictures from an area that usually sees some of the hottest temperatures on earth during the summer.
Now, it’s not uncommon for the temperature across even the hottest of deserts to drop tens of degrees Fahrenheit at night, meaning any unusual snow could stay there around for a while. But photographers at the scene said the snow actually stayed intact (完好无损的) for a good portion of the day.
“We were really surprised when we woke up to see snow again,” photographer Karim Bouchetata told Shutterstock. “It stayed all day on Sunday and began melting at around 5 p. m.” While snow is not often falling down in the desert area, a similar snow phenomenon happened just last year. Before that, it had been 37 years since Ain Sefra’s last snowfall.

My mother used to ask me what is the most important part of the body. Through the years I would guess at what I thought was the correct answer.
When I was younger, I thought sound was very important to us as humans, so I said, “My ears, Mommy.” She said, “No. Many people are deaf. But you keep thinking about it and I will ask you again soon.”
Several years passed before she asked me again. Since making my first attempt, I had contemplated (仔细考虑) the correct answer. So this time I told her, “Mommy, sight is very important to everybody, so it must be our eyes.” She looked at me and told me, “You are learning fast, but the answer is not correct because there are many people who are blind.”
Over the years, Mother asked me a couple more times and always her answer was, “No, but you are getting smarter every year, my child.”
Then last year, my Grandpa died. Everybody was hurt. Everybody was crying. My Mom looked at me when it was our turn to say our final good-bye to Grandpa. She asked me, “Do you know the most important body part yet, my dear?”
I was shocked when she asked me this now. I always thought this was a game between her and me. She saw the confusion on my face and told me, “This question is very important. It shows that you have really lived your life.” I saw her eyes well up with tears. She said, “My dear, the most important body part is your shoulder.”
I asked, “Is it because it holds up your head?”
She replied, “No, it is because it can hold the head of a friend or loved one when they cry. Everybody needs a shoulder to cry on sometimes in life, my dear. I only hope that you have enough love and friends that you will have a shoulder to cry on when you need it.”
Then and there I knew the most important body part is not a selfish one. It is sympathetic to the pain of others.

C.At the station. D.At the funeral.
4.What can we learn from the passage?
A.We should learn to understand others’ pain.

Last summer, our class paid for a visit to a local nursing home. After arrive there, we saw some elder practicing Tai Chi. They gave us a good impression of being dynamic and healthy. But there were also some old people seating in the wheelchairs. They were out of shape，what made me a bit sad. They must have experienced hard life in the past. During the visit, we chat with the old and did some cleaning and washing here. We had such a good time. This year, we plan to visit it from time to time but hope more people will care about the old so that they can be healthy, peace and happy for the rest of their life.
