     Massachusetts today looks nothing like it did when the first English settlers arrived. Back in the 17th

century, forest blanketed the land. Today, roads and towns cover much of the area. But the past is not

dead and gone. Just an hour's drive from Boston lies Plimoth Plantation.

     There you'll experience the 17th century life from the days of tAe Pilgrims (清教徒移民). You can

look in the Pilgrims' homes, watch the way they cook, and ask them about their daily lives. You can even

help them build houses or work in the fields.

     When you arrive at Plimoth, you are greeted with "How do you fare?" instead of "How are you?" In

this living history plantation, actors portray (扮演) real people of 17th-century Plymouth. Each actor has

taken the identity of someone from that period. All the actors speak the language of Shakespeare. They're

happy to talk about the hardships of their lives or just share the gossip of the day. But don't try to discuss

modem topics. They won't understand what you are talking about!

     In fall, you can enjoy a harvest dinner very similar to the first Thanksgiving. You'll dine with your hands

like Pilgrims. You'll find no pepper on the table. This expensive spice was used only sparingly (节俭地) in

cooking. You'll find no last-course "dessert" either. At the time, people ate sweet dishes right along with the

meal.

     Cranberries were on the menu then and still are today. A short distance from Plimoth, you can visit

Cranberry World. At this unique museum, you'll see how cranberries are harvested and can taste different

cranberry products.

     Of course, the first Thanksgiving included not only the Pilgrims, but also their Wampanoag guests. If

you want to find out something about the Wampanoag, explore a re-created Wampanoag Home Site. It is

just a short walk from Plimoth. Step into the Native American home and enter a different world. Native

Americans dressed in 17th-century Wampanoag outfits (服装) describe how their people lived 400 years

ago. Outside, you can help make a traditional boat or learn about native plant remedies (治疗法).

     Much in Massachusetts has changed since the 17th century. But in Plimoth, the past lives on.
