Even if you’re not an astronomy fan, chances are that you can easily recognize certain constellations (星座) and stars such as the Big Dipper (北斗七星) and the North Star.

The North Star is the brightest star in the constellation known as the Little Dipper. It is so-called because of the special position. If you were to stay up all night looking at the stars, you’d slowly see them move around a point in the sky known as the North Celestial Pole.

You would notice, however, that one star remains still. This is the North Star, so named for its location almost directly in line with the North Celestial Pole.

Due to its position in the sky, at one time sailors used the North Star as a navigational tool. By measuring the angle between the northern horizon and the North Star, a navigator could accurately determine the ship’s latitude.

But latitude, or the imaginary lines stretching across the globe parallel to the equator, was not enough to plot a ship’s location. Knowing latitude only allowed navigators to locate themselves on a particular latitude line at a particular distance from the equator. It was only with the invention of a way to accurately measure longitude that precise navigation became possible.

Although the North Star is no longer used by navigators, it remains a heavenly symbol of human curiosity and exploration.

1.Which of the following statements about the North Star is TRUE?

A. The North Star is the brightest star in the night sky.

B. The North Star, together with some other stars, make up the Little Dipper.

C. The North Star moves along the same course with other stars.

D. The North Star is exactly located in line with the North Celestial Pole.

2.What can be inferred from the passage?

A. The North Star could help navigators set a straight course of their ship in the past.

B. Real lines that are parallel to the equator are called “l(fā)atitude”.

C. Either latitude or longitude could make precise navigation possible.

D. Now the North Star is no longer a navigational tool used by sailors.

3.Which is probably the best title of the passage?

A. What is a navigational tool?

B. What can be called the earliest GPS?

C. What makes the North Star so special?

D. What is the symbol of human exploration?

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(dá)) 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)).

科目:高中英語 來源:2015-2016學(xué)年河南鄭州第一中學(xué)高一上期中英語試卷(解析版) 題型:閱讀理解

The film stars out as a normal day at a typical American high school. Friends chat in the dining room and boys play football. But there's big surprise when the movie ends with two students going crazy in the school-shooting and killing people.

This is Elephant. It stars real school kids. American director Gus Van Sant had no ready-made lines. The student actors made up their own dialogue, with Van Sant asking them to base their characters on their own lives.

Although it may not sound very high quality, the film won the Palme d'Or (金棕獎) for Best Film and the award for Best Director at the Cannes film festival.

The film is based on the shootings at a high school in the US, where two boys killed 13 people and then themselves in 1999.

The title of the movie refers to the old expression about a problem that's as hard to ignore as an elephant in the house.

The film takes a close look at a few hours in the lives of the victims and the killers. It shows how high school is a different experience for everyone---fun and friendly, or hard and lonely.

In many ways, the two boys, who carry out the shooting, act like ordinary kids. They joke around with one boy's mother as she serves them cakes and play the piano.

But there're hints of the anger they feel inside. One of the boys is bullied (欺負(fù)) at school. The other plays violent video games. But Van Sant isn't blaming their killings on either bullying or violent games. In fact, the film doesn't offer any reason for why school violence happens.

"I didn't want to explain anything. It's up to the audience to draw its own conclusions," said the 51-year-old director.

1.The lines of the film were ________.

A. given by the director

B. created by student actors

C. thought out by the director during the acting

D. carefully designed by professional people

2. The film doesn't tell why school shootings happen________.

A. so as to leave room for the audience to think and judge

B. because life itself is the problem maker

C. because the mental problems of students are hard to explain

D. but there are some hints of the reasons

3.The film is named Elephant because ________.

A. an elephant is always gentle and never causes trouble

B. an elephant is a symbol of big problems in American schools

C. elephant is used to suggest that the school crime is a big problem

D. the two boys liked elephants when alive

4.What’s the passage mainly about?

A. It shows American school life.

B. It introduces the film Elephant.

C. It tells people to be careful while in peace.

D. It reports a school killing in a US school.
