1 . The mama﹣bear instinct

Ms． Angela McQueen， a math and PE teacher at Mattoon High School， Illinois， has a routine when she's on lunch﹣monitoring duty． She    1     （keep） an eye on the hundreds of students in her charge by walking laps（圈） around the school cafeteria．

In September 2017， McQueen， then   40， had hardly finished one lap    2       a 14﹣year﹣old freshman standing not far from her pulled out a gun． She knew too well that he was going to start shooting．

School employees    3    （train）on how to handle active shooters：Attack their ability    4     （aim）． So with the shooter's finger on the trigger， McQueen rushed to him．    5    （grab） at his arm， she forced the gun into the air， but not    6     he struck one student in the hand and chest and hurt another． As students ran for the exits， McQueen defeated the shooter with help from the school resource officer，    7     disarmed   the student and took him into imprisonment until police arrived minutes later． Afterward， McQueen went outside to give hugs and support to her shaken students．

"It's the mama﹣bear instinct，" she told the local paper． "I don't have kids of my own， but these are still‘    8    ' kids．"

    9     McQueen， a story that has played out tragically at far too many schools across the country had a relatively happy ending． "If it hadn't been for her， the situation would have been a lot different，" Police Chief Jeff Branson said at a news conference．

As one    10     （impress） student told CBS News， "Mr． McQueen is our heroine．"
