【題目】 Some people wonder why countries spend millions of dollars on space projects. They want to know how space research helps people on Earth. Actually, space technology helps people on Earth every day. This is called “spinoff technology”. Spinoff technology is space technology that is now used on Earth.

In early space programs, such as the Apollo missions(任務(wù)) of the 1960s and 1970s, and in the space shuttle missions today, scientists developed objects for the astronauts to use on the moon and in space. We now use some of these objects every day. For example, we have Quartz clocks and watches with an accuracy of one minute a year. We purify the water we drink with a water filter(過濾器) designed for the astronauts' use in space. The cordless, hand-held tools we use in our homes, such as cleaners, flashlights, drills, and irons came from the technology of these early space programs.

On cold winter days, we can stay warm with battery - operated shoes and socks, and insulated(絕緣的) coats and jackets. All of these clothes are similar to the spacesuit designs that keep astronauts comfortable in the temperatures of the moon, and are spinoffs from space technology.

These products are only a few examples of the many ways space technology helps us in our everyday life. No one knows how new spinoff technology from the International Space Station will help us in the future.

【1】Which of the following is NOT a spinoff?

A.Water filtersB.Quartz watchesC.Battery- operated socksD.Spacesuits worn by astronauts

【2】The underlined part “purify the water” probably means “make the water ”.

A.lightB.cleanC.brightD.warm

【3】Which of the following is the best title of the passage?

A.Future of Space TechnologyB.History of SpinoffsC.Spinoff Technology D.Space Projects

【4】From the passage, we can infer(推斷) that the writer .

A.believes that space technology will be widely used on Earth

B.doubts if spinoffs have any good effect on human beings

C.agrees to do more research on spinoff technology

D.suggests using more spinoffs in our daily life

【答案】

【1】D

【2】B

【3】C

【4】A

【解析】

本文主要介紹了太空技術(shù)的“衍生技術(shù)”在地球上的廣泛應(yīng)用。

【1】推理判斷題。根據(jù)For example, we have Quartz clocks and watches with an accuracy of one minute a year.和On cold winter days, we can stay warm with battery - operated shoes and socks, and insulated(絕緣的) coats and jackets. All of these clothes are similar to the spacesuit designs that keep astronauts comfortable in the temperatures of the moon, and are spinoffs from space technology.可知，太空技術(shù)的“衍生技術(shù)”有石英鐘，手表和帶電池的鞋和襪子。故選D。

【2】詞義猜測題。根據(jù)we drink with a water filter(過濾器) designed for the astronauts' use in space.可知，用過濾器過濾水，是為了讓水干凈，故選B。

【3】概括歸納題。根據(jù)Actually, space technology helps people on Earth every day. This is called “spinoff technology”. Spinoff technology is space technology that is now used on Earth.可知，本文主要介紹了“衍生技術(shù)”。故選C。

【4】推理判斷題。根據(jù)These products are only a few examples of the many ways space technology helps us in our everyday life. No one knows how new spinoff technology from the International Space Station will help us in the future.可知，太空技術(shù)將在地球上廣泛使用。故選A。

認(rèn)真閱讀題干，根據(jù)題干要求，在文中尋找答案所在的語句或段落，進(jìn)行分析理解，詞義猜測，推理判斷和概括歸納，選出正確的選項(xiàng)。例如小題2，根據(jù)we drink with a water filter(過濾器) designed for the astronauts' use in space.可知，用過濾器過濾水，是為了讓水干凈，故選B。

【題目】 Have you ever tried to write a poem(詩，詩歌)? It’s easier than you might think. Just pick up a pen and begin practicing. Here are the steps to write a poem.

Choose your topic.【1】 Some people can start writing poems without really deciding what to write about; when their pen or pencil hits the paper, the words just flow (暢流). Most people, on the other hand, need a topic and as a beginner, this is the best way to start. It’s easier to write a good poem about something you know well or you have experienced.

Free write for five minutes about your topic. Then go back and read it. Are any words or expressions especially good? 【2】 For example, if you are describing something (a bird), write down descriptive words about it (looks, colors), and the kind of story you would like to tell about (the bird fell out of a tree). If you are writing about an event in your life, write down your feelings and thoughts of that event.

Write your poem. Remember, a poem doesn’t have to rhyme(押韻).【3】 But it should show your feelings of the topic. And it should sound nice to you.

Have a friend read your poem aloud to you.

【4】 If not, go back and rewrite the parts you don’t like.

【5】 Read it to others. Read it aloud to yourself. Put it somewhere if you want.

A. Do you like the way it sounds?

B. Mark(作記號) them and use them in your poem.

C. Enjoy your poem.

D. What would you like your poem to be about?

E. It doesn’t have to use sentences, either.

F. It’s very easy to write a poem.

G. Read your poems loudly when you are free.
