L4-U2-P3 Alcatraz 1 🔱恶魔岛

Alcatraz is a small island in San Francisco Bay，1.5 miles from San Francisco

From Alcatraz，you can see the famous  Golden Gate Bridge

Alcatraz is also famous and is  now a major tourist attraction

Tourists can reach the  idland by boat from the city

Alcatraz  has often appeared in movies，including “escape from Alcatraz” which was made in 1979

One reason it's famous is because it used to be a prison，a very special prison

It was designed for prisoners who were causing trouble in other prisons，such as trying to escape

It was a maximum security prison，so escape is almost impossible

The waters around it are cold，and only very strong swimmer can swim from the island to San Francisco

The first group of prisoners arrived in 1934

There were 137 prisoners，including bank robbers and murderers

They came by train from another prison in the state of Kansas

During that trip there was heavy security

The prisoners were under guard and handcuffed

Nobody wanted then to escape
