    When a baby cries, its parents will check on it as soon as they can and make sure it is okay. According to a new study, a baby's cry can make adults react very quickly, even if they are not related to the baby.

Oxford University researchers used the classic game whack-a-mole （打地鼠） for the study.

    Whack-a-mole requires people to hit one of nine  {#blank#}1{#/blank#} (button). Players must react as quickly as they can to whichever of the buttons that lights up. It is a game that requires speed and accuracy （准确度）. The study invited 40 men and {#blank#}2{#/blank#} (woman) aged 19 to 59. Some of them had sons or daughters, although none of {#blank#}3{#/blank#} (they) children were babies. They played whack-a-mole after listening to different sounds, {#blank#}4{#/blank#} (include) the babies' crying, the crying of adults in trouble and bird songs {#blank#}5{#/blank#} (play) at a similar pitch （高音）to the babies' crying.

    The volunteers' scores were  {#blank#}6{#/blank#} (high) after listening to the sound of crying babies. Men and women had similar scores overall. The results showed that hearing a crying baby can trigger a reaction in adults.

"It's almost  {#blank#}7{#/blank#}  (possible) to ignore （忽视） crying babies {#blank#}8{#/blank#} planes. This is true even though there are so many other noises around," said Morten Kringel bach, the scientist  {#blank#}9{#/blank#} led the study. He added that in the course of human evolution （进化） taking care of babies has always been  {#blank#}10{#/blank#} important job for adults. When a baby is hungry, it will cry. As a result, human brains develop a special reaction to a baby's cry.

Dear Mom,

Today is Sunday. I don't go {#blank#}1{#/blank#} school. I stay at home. So I can {#blank#}2{#/blank#} (write) to you now. Every day, I go to school {#blank#}3{#/blank#} seven thirty in the morning. We have four {#blank#}4{#/blank#} (lesson) in the morning. We read {#blank#}5{#/blank#} write in Chinese at school.

There are fifty-five students in my class. Four of {#blank#}6{#/blank#} (they) are Americans. The other students are {#blank#}7{#/blank#} (China). Chinese people are friendly. Now I have some Chinese {#blank#}8{#/blank#} (friend). My classmates {#blank#}9{#/blank#} (be) all my friends. They teach {#blank#}10{#/blank#} (I) Chinese. I can speak a little Chinese now. Please don't worry about me.

Yours,
Kate
