UFO stands for "unidentified flying object". Many people reported having seen UFOs in the sky. A lot of countries tried to research them and in 1952 they got the name of UFO.

There were several reports published in the 19th century which were related to UFOs. Denison Daily News in its report of 25th January, 1878 wrote that a farmer, Martin, saw a flying object in the sky and it was just like a plate. This was the first time that the word plate had been related to the UFOs.

The first reports on UFOs came during World War II. In 1947 pilot Kenneth Arnold said while he was flying near the Mount Rainer he saw a very bright object in the sky. He said that it was like a plate too. The information given by Kenneth got lots of attention from the media and people.

Several research organizations gave their reports on the UFOs. They showed direct or indirect physical evidence of the UFOs, and sometimes UFOs’ appearance was found on the radar (雷達) screen. Many people tried to take video tapes or photos of the UFOs as testimony. Most UFOs are in saucer shape while many UFOs are like a cigarette or a half ball.

Many films and TV shows are made about UFOs. There are two famous movies which are created on the theme of UFOs and aliens, War of the World and Star Wars. UFOs have created a new field in science which is known as Ufology (飛碟學(xué)).

1.Which of the following is TRUE according to the passage?

A. The UFOs Martin and Kenneth Arnold saw were in different shapes.

B. People named the flying object UFO in the 19th century.

C. Martin was the first person that described the flying object as a plate.

D. Kenneth Arnold was given little attention for his discovering UFO.

2.What does the underlined word " testimony " in the fourth paragraph mean?

A. Evidence. B. Research.

C. Mystery. D. Appearance.

3.The next paragraph following the passage might talk about ________.

科目：高中英語 來源：2015-2016學(xué)年山西大同一中高二3月月考英語試卷（解析版） 題型：閱讀理解

Across the United States, universities and colleges have been looking to become more sustainable (可持續(xù)發(fā)展的) and more than 600 schools have already planned to become eco-friendly. The EcoDorm, home to 36 students at Warren Wilson College in Swannanoa, was designed to be sustainable from top to bottom, or in this case, from its rainwater-collection system to its garden. The dormitory is bringing new meaning to the concept of living “green” at college.

At Warren Wilson College, a biological science school with fewer than 1,000 students, the sustainability drive came from the student body. The EcoDorm concept was presented ten years ago by two students; a planning committee firstly suggested using building materials like corncob. Although the architects disagreed with the idea, they came up with other creative solutions: Wood siding was taken from the trees grown in the school yard that were suffering from a disease, and rainwater was collected in an old railway car and pumped back into the house to clean the toilets.

All in all, the dorm uses nearly two-thirds less electricity than a similar-sized traditional building would. But even the most sustainable homes need continued efforts from its livers. And in the case of EcoDorm, students live by their words. Most also take advantage of the dorm’s bio-garden, planting and harvesting fruits and vegetables. “I didn’t have to worry about paper towels being wasted or feel bad about drying my clothes outside,” Jeremy Lekich, the dorm’s gardener, said. “Basically, it has made my life easier.”

1. We can learn from the text that the EcoDorm in the US .

A. offers students the chances to have a natural living at college

B. was firstly built by two college students

C. was designed for saving building materials

D. is only applicable in few schools

2. The second paragraph is mainly about .

A. where the EcoDorm was built

B. when the EcoDorm got its name

C. what the EcoDorm is made of

D. how the concept of EcoDorm started

3. What can be inferred from the text?

A. A long-term development calls for students’ efforts.

B. Students’ ideas should be encouraged at college.

C. Green living is a new trend at American colleges.

D. Students can learn to protect the environment through practice.

Last summer vacation, I went back to my hometown to visit my grandparent. They had several cows in their yard. One day, one of them were ill, but it didn’t want take any medicine. An animal doctor came and gave it an injection. After a while, and it seemed to be better, so I decided to feed it anything. I fed it carrots, which were cutting into small pieces. I also fed it milk powder with pills in them, just as a doctor told me. Although looking after an ill cow was a tired job, I felt a sense of achievement as it begins to recover.
