As the leaves change color in autumn, students return to school.As a frost covers the ground each night, we are busy planting vegetables in northern Wisconsin.

Five public school districts in northern Wisconsin recently built high tunnels (隧道) for the winter growing season.The schools’ high tunnels, made of metal frame and a plastic covering the raised beds, keep plants warm enough to extend the growing season through the winter and allow an earlier spring planting.Our very short growing season occurs almost entirely during the summer vacation months.This makes the high tunnels necessary in allowing students to gain experience of growing and marketing produce in a cold climate where production at this scale couldn’t otherwise happen during the school year.

During the summer, the high tunnels on school grounds still need to remain there.We developed the Agripreneur program(Agriculture + Entrepreneur) to support students’ work in the high tunnels during months when students are are on holidays.This program was made possible by a farm and a university.Each summer, a pair of students will be hired from every high school to care for and sell a single crop in exchange for instruction from professional lo-cal farmers, growing experience, and a salary.

The Agripreneur program appeared for its first season during the summer of 2015.Students grew tomatoes that were sold to community members, local restaurants and the school cafeterias（食堂）.The program met its goal of increasing the number of local vegetables consumed, both within the region and in school lunches.Sales to school cafeterias will continue through the winter as the high tunnels’ change to nutrient root vegetables, all grown by students.

We may live in winter, but with the recent addition of these school high tunnels, our students are able to eat the freshest local vegetables available—even during the coldest months.

1.What do we know about the school’s high tunnels?

A. They are actually greenhouses.

B. They are actually metal containers.

C. They are entirely used for planting vegetables in summer.

D. They are mainly used as reading rooms for students.

2.High tunnels are being used in the school districts because of ______.

A. students’ interest in planting.

B. the larger need of crops there.

C. the short growing season there.

D. no fresh vegetables available there.

3.The Agripreneur program was created to______.

A. get farmers to produce more crops.

B. check students’ work on the high tunnels.

C. get instructions from professional local farmers.

D. help students do their work in the high tunnels in holidays.

4.What can be the best title for the text?

A. Crops Are Planted in Winter

B. Students Are Becoming Scientists

C. Schools Have the Vegetable Market

D. New Growing Season Begins Under High Tunnels

Here are some undiscovered places around the world, which will surely impress you.

Byblos, Lebanon

This quiet settlement north of Beirut in Lebanon has been around a really long lime. Today, its rich history is well-represented in its ruins, which include ancient temples and tombs and Neolithic houses. Three sites in particular steal the show: the restored Roman amphitheatre (圓形劇場）, the grand 12th century Crusader castle, and the beautiful]y restored medieval open market.

Carreg Cennen, Carmarthenshire, Wales

The ruins of Carreg Cennen must be among the most noticeable sites in Wales. Carreg Cennen is defended by two drawbridges and three gate towers, although it hasn’t seen much action since it was partly damaged in 1462, during the Wars of the Roses. However, one rare feature of the castle is unchanged. Ifs the stone passage that leads down to a natural cave underneath.

Providence, Rhode Island, US

Rhode Island is the smallest state in the US. Its capital, Providence, has many of the attractions. Ivy League member Brown University and the famous Rhode Island School of Design (RISD) give the city a strong student influence. Up on College Hill, east of the Providence River, are streets lined with 18th century wood framed houses.

Sequoia National Park, California, US

Not content with having the worlds tallest (coast redwoods) and oldest (bristlecone pines), California is also home to the largest tree—the giant sequoia (紅杉樹). It grows only to its lull size in the Sierra Nevada mountains. Many of these trees are found in the Yosemite National Park, but for more quality time with the trees, it's best to head south to the far less known Sequoia National Park, which gets a quarter of Yosemite’s visitor numbers.

1.What do Byblos and Carreg Cennen have in common?

A. They were once destroyed in the history.

B. They are defended by two drawbridges.

C. They are most famous for their temples.

D. They are located in the same country.

2.If you’re interested in old house made by woods, you’d go to the place in .

A. Lebanon B. California

C. Rhode Island D. Carmarthenshire

3.Who would most probably go to Sequoia National Park?

A. People who love walking in streets.

B. People who are interested in visiting castles.

C. People who want to feel a strong student influence.

D. People who are interested in tress.

4.What can we learn from the passage?

A. Rhode Island is the smallest state in the world.

B. Yosemite National Park is located in California.

C. The Carreg Cennen castle has been totally changed. v

D. The medieval open market in Byblos has never been destroyed.

Parents annoyed by their children’s picky eating habits have taken to social media to share a host of creative ways to deal with them in a new thread gaining popularity online. In these lunch box notes posted onto sites, mothers and fathers have used threats, persuasion and even little white lies to talk their youngsters into finishing their sandwiches.

One talented father created the tag “Dadfact” in an effort to persuade his child into eating their sandwiches using information that might not be completely reliable. He scribbled on a napkin, “Every time you don’t eat your sandwich a unicorn(獨(dú)角獸) dies Dadfact Love, Dad”. A further technique from a separate note was a drawing of a scary monster, ordering the little one to, “Eat your food!”

Everyone knows coming to terms with bread crusts is a difficult job. One parent’s inspiring note encouraged their child to leave the world of crustless sandwiches behind. They wrote, “I left the crusts on. Today is the first day of the rest of your life.”

Another cheered on their child with a note which read, “You can do it! Love yourself.” A father appeared to be laying down the law when he wrote, “New rule: I will keep packing this sandwich until you eat it. Good luck. Love, Dad.”

One youngster Julian retorted (反駁) with a handwritten moan of his own. When his mother wrote to him, saying, “Dear Julian, have a great day, love Mom”, he replied simply on the same piece of paper, in big letter, “I will not.”

But cheery parents shared more positive feelings on post— it’s attached to their children’s lunch. A mother wrote, “Have a great day! I love you.” Another simply put, “You are my sunshine.”

Other parents shared jokes in their children’s lunchbox to perk them up during the day. One included, “When do astronauts eat? At launch time.” And another shared, “Why did the student eat his homework? Because the teacher said it’s a piece of cake.”

1.What does the underlined phrase “perk...up” mean in the last paragraph?

A. make active B. make feel proud

C. give promise D. give praise

2.By saying “Every time you don’t eat your sandwich a unicorn dies Dadfact Love, Dad”, the parents are actually giving their children ________.

A. persuasion. B. encouragement.

C. threats. D. white lies.

3.Most parents leave notes in their children’s lunch boxes by _____________.

A. drawing pictures B. playing word games

C. quoting sayings D. using further technique

4.How do the children respond to the notes according to the passage?

A. The children are very particular about the notes.

B. The children are greatly motivated by the encouraging notes.

C. Not all children feel cheered and inspired at the notes.

D. None of the children are touched by the messages in the notes.
