【题目】With golden sunshine and a gentle breeze (微风), autumn is the most beautiful seasons in the year. This is a great time to go outside and have fun. Go to a valley to see red maple trees , go and pick fruit in an orchard or find an open field to fly your kite in.

However, for many high school students, these great activities may be just a dream. With plenty of work to do, they spend all their hours indoors, struggling for a high mark in their exams. Of course, study is one of the most important things for teenagers. But life is definitely much more than that.

Sometimes we spend so much time studying that we forget how to make life wonderful. In doing so, we lose the real purpose of life —to be a valuable and happy person. To enjoy just how great it is to be alive, we have to put down our books and pens and look around us. Students, take some exercise to improve your health, talk with your parents and friends for understanding and walk around outside to refresh (振作) your body and mind.

Going out and enjoying the beautiful countryside often helps our creativity in our work. Chinese craftsman, Lu Ban created a saw to help woodworkers. But if he hadn't walked outside, he would not have been inspired by a kind of toothed (锯齿状的) grass. We could also suppose if Newton hadn't rested under that apple tree, then he wouldn't have been hit by an apple, and his classic (经典的) theories would not have come out.

Going out is not only a break from hard work, but a chance to add to life experience. So come on, give your brain a good rest. Step out of the books and get your bag ready for an autumn outing. We are sure you will get much more than knowledge from the exciting journey.

【1】In which paragraph does the writer make a summary about his opinion?

A．Paragraph 1. B．Paragraph 2.

C．Paragraph 5. D．Paragraph 4.

【2】Why is going out a dream for many high school students?

A．They are unhappy to do so.

B．Their parents don’t allow them to do so.

C．They have too much work to do for getting high marks in the exams.

D．They think study is the most important thing for them.

【3】Which of the following ISN’T the reason for high school students’ going out?

A．To improve their health.

B．To invent a new product.

C．To develop their creativity.

D．To refresh themselves.

【4】The passage is developed mainly by______________.

A. describing the beautiful scenery in Autumn

B. pointing out the present situation of high school students

C. making predictions (做预测)

D. reasoning and giving examples

【5】What can you learn from the passage?

【题目】Each Sunday, people can hear the music of the Mission Dolores Basilica in San Francisco. The Spanish missionaries（传教士）built the church in 1791. It was the start of a special kind of neighborhood: the Mission District.

The area is a place with a long and varied history. One community member says that it’s important for people to understand the many levels of history in the neighborhood. He feels that_______is a big part of understanding what it means to be a real San Franciscan.

One of the most interesting parts of the district is its people. Over the years, immigrants have come to the area from Ireland, Germany, and Italy. But the most recent immigrants are mainly from Latin America. It’s easy to see the style that these recent additions give to the neighborhood. You can see it in the art on the walls, taste it in the food, and hear it in the music!

Juan Pedro Gaffney, the director of the Spanish Choir（唱诗班）of San Francisco, says that the people there share the pain and the happiness of their friends and family members and that music has always been a basic part of cultural identity in the district. He feels that the music of the district is colorful and lively.

But it isn’t just its music that’s colorful and lively. Its art is full of life as well.

The local art community stays close to the area’s culture and tradition. A local arts organization often leads people on walks through the district. They visit streets like Balmy Alley, which is famous for its murals （壁画）. Even though the meanings behind the murals are always changing, they are still very powerful. One artist explains that they are fighting for fairness in the community and to help the environment through murals. Apparently, they’re something the community likes.

Many of these artists feel that the district is a successful neighborhood where new immigrants are welcome. “People see that they’re not so different from each other,” says one artist. “There are a lot of things that bind（捆绑）the immigrants through culture and tradition.”

【1】The underlined phrase “this knowledge” in Paragraph 2 refers to ____________.

A. having memories of the Spanish missionaries

B. knowing the history of the Mission Dolores Basilica

C. realizing what it means to be a real San Franciscan

D. understanding the many levels of history in the neighborhood

【2】The author shows the multi-culture of the Mission District from the aspects of ____________.

A. literature and sports

B. music and murals

C. buildings and clothes

D. customs and festivals

【3】It can be inferred from the passage that in the Mission District ____________.

A. immigrants from different cultures live in harmony

B. Latin American music and foods are the most attractive

C. the Spanish Choir stands out in the competition of different cultures

D. new immigrants have to give up their own culture to be welcome

【4】What would be the best title for the passage?

A. The Mission Dolores Basilica

B. A Special Type of Neighborhood

C. Music of the Mission District

D. The Spanish Choir of San Francisco
