　　The most famous war movies reflect the American public's continuous fascination with World War II and the Vietnam War. Many movies of this kind have been well-received when they were first shown, but few of them have enjoyed lasting fame and popularity. The films on the list of the five most famous war movies still remain fresh and are popular among many people.

　　The Longest Day

　　An all-star cast recreates D-Day and the Normandy attack, the greatest landing and aerial(空中的) invasion in history. This is probably the most famous war movie because of the large number of big stars who have roles in the film.

　　Apocalypse Now

　　This is a famous war movie because of its description of the Vietnam War and excellent performance from Marlon Brando, Martin Sheen and Robert Duvall. The film, full of memorable scenes and quotes, is widely viewed as a masterpiece of movie making.

　　The Dirty Dozen

　　Lee Marvin, playing an officer who thinks and acts independently, is appointed to train twelve prisoners, most of whom have been sentenced to death, to go on a suicide mission to kill several Nazi generals. If_any_of_the_men_makes_it_back,_they_may_get_a_pardon. This is one of the most popular war movies ever made.

　　Platoon

　　This famous war movie is the fictional account of a platoon(排) in Vietnam that is divided into two competing groups. The plot is partly based on the director Oliver Stone's real life experience.

　　Midway

　　This is probably the most famous war movie ever made about navy. It's based on the battle between Japanese and American aircraft carrier groups near Hawaii in World War II that resulted in a decisive American victory.

　　文章大意：本文介紹了美國最杰出的五部反映二戰(zhàn)和越戰(zhàn)的經(jīng)典戰(zhàn)爭片。

　　1．What are the most important themes of the movies mentioned above?

　　A．World War II and the Vietnam War.

　　B．Competitions in the Vietnam War.

　　C．Fights between Nazi generals and soldiers.

　　D．D-Day landing and the Normandy attack.

　　答案：A　細(xì)節(jié)理解題。由第一段前兩句話可知。

　　2．The text is meant to ________.

　　A．describe five most famous movie posters

　　B．choose the best war movie among the five

　　C．introduce five masterpieces of American films

　　D．celebrate the success of the five American films

　　答案：C　推理判斷題。由文章大意可知。

　　3．What can we infer from the underlined sentence?

　　A．The prisoners will be punished if they fail.

　　B．The prisoners might be willing to have a try.

　　C．The prisoners might be scared and run away.

　　D．The prisoners have to take Nazi generals back.

　　答案：B　推理判斷題。畫線句意為“如果他們能夠完成任務(wù)歸來，那么就能赦免他們的罪”，所以這些死刑犯很可能會(huì)愿意嘗試一下。該題易誤選A項(xiàng)和D項(xiàng)。

　　Water Robots Explore the Celtic Sea

　　Scientists in England are using two self-directed water vehicles to explore the animal and plant life of the Celtic Sea. The Celtic Sea is a body of water off the southern coast of Ireland. The area is known for its exceptional sea life. Scientists want to know why sea animals are so attracted to this part of the Atlantic Ocean.

　　One of the research vehicles is powered by batteries. It collects information for the National Oceanography Center in Southampton, England, and the World Wildlife Fund. The vehicle's low energy requirements permit it to stay afloat for up to 30 days. Reports of what it finds in the Celtic Sea are sent by satellite. Stephen Woodward is an engineer who helped design the craft. He says the vehicle has equipment that can detect small organisms called zooplankton and fish. He adds that other sensing devices measure water currents and other features of sea life. The vehicle also creates a two-dimensional(二維圖)map of the sea.

　　Another vehicle is powered by solar panels and a wind turbine(渦輪機(jī)). It can stay afloat for months. The robotic vehicle sends information about the so-called biodiversity hotspots. A biodiversity hotspot is an area of an ocean that has a lot of plant and animal life activity. Lavinia Suberg is one of the scientists studying the biodiversity of the Celtic Sea. She says productive ocean areas, like the Celtic Sea, attract zooplankton. The zooplankton then attract fish. She adds that areas with a large increase of fish often attract sea mammals and birds.

　　Using these robotic ocean vehicles greatly reduces the cost of exploring the seas with manned laboratories. Scientists can spend more time analyzing the collected information. They say the research will give them a better understanding of the needsof the Celtic Sea for future management and protection.

　　文章大意：本文介紹兩種水下自我探測器，它們用來勘探海底動(dòng)植物。

　　4．Scientists go to the Celtic Sea to explore ________.

　　A．why this area appeal to sea animals

　　B．what the Celtic Sea really desires

　　C．whether the expense can be reduced

　　D．how this area can be better protected

　　答案：A　細(xì)節(jié)理解題。根據(jù)第一段最后一句話“Scientists want to know why sea animals are so attracted to this part of the Atlantic Ocean.”可知，選A。

　　5．According to paragraph 2, the research vehicle ________.

　　A．is used only to measure water currents

　　B．is designed by the engineer called Lavinia

　　C．can also create a three-dimensional map

　　D．can detect the zooplankton and sea life

　　答案：D　細(xì)節(jié)理解題。根據(jù)第二段第六、七句話“He says the vehicle has equipment that can detect small organisms called zooplankton and fish. He adds that other sensing devices measure water currents and other features of sea life.”可知，選D。

　　6．Which of the following is TRUE?

　　A．Both of the vehicles are powered by batteries.

　　B．Neither of the vehicles can stay for months.

　　C．The vehicles help reduce both time and money.

　　D．Reports are sent by the scientists themselves.

　　答案：C　推理判斷題。根據(jù)第四段第一、二兩句話“Using these robotic ocean vehicles greatly reduces the cost of exploring the seas with manned laboratories. Scientists can spend more time analyzing the collected information.”可知，選C。

　　7．What is the purpose of the passage?

　　A．To call on us to protect the sea.

　　B．To introduce two water robots.

　　C．To inform us of sea exploration.

　　D．To arouse our interest in sea life.

　　答案：B　推理判斷題。從文章第二、三段大意可知，本文主要介紹兩種水下自我探測器。故選B。
