【解析】

短文主要介紹鼻涕的作用及人們流鼻涕的原因。

【1】句意：流鼻涕并不總是意味著你感冒了。

考查動詞詞義辨析。通常，流鼻涕是感冒的一個病征。但并不是所有的流鼻涕現(xiàn)象都說明感冒了。所以此空填mean，意為“意思是，是指”。故選E。

【2】句意：當(dāng)你呼吸時，鼻涕可以粘住空氣中的灰塵。

考查動詞詞義辨析。當(dāng)人們呼吸，吸入空氣，鼻涕就會粘住其中的灰塵。所以填breathe，意為“呼吸”。故選C。

【3】句意：這幫助保護(hù)人們的喉嚨和肺。

考查動詞詞義辨析。上文說，鼻涕還可以使人們吸入的空氣更濕潤。這其中的作用就可以保護(hù)人們的喉嚨和肺，所以填protect，意為“保護(hù)”。故選B。

【4】句意：當(dāng)鼻涕太多的時，它無處可去。所以就從鼻子流出來了。

考查閱讀理解及邏輯推理能力。下文說，鼻涕從鼻子流出來，其原因是，“鼻涕太多，無處可去”。所以填anywhere，意為“(用于否定句和疑問句，代替somewhere)在任何地方”，而it doesn’t haveanywhereto go意為“它無處可去”。故選A。

【題目】 Do you like making paper planes? If you like origami (折紙), we're sure you enjoy making paper planes, too. All it takes is some paper and a new simple supply. And paper planes can be fun to fly around the houses or outside the yard.

No one knows for sure when the first paper plane was created. Sometimes, historians give credit to Leonardo da Vinci. However, paper folding and kite making were both popular in Asia hundreds of years ago, so it's likely that the first paper plane may have been made long, long ago.

In some Asian countries, the art of folding paper is called origami. Some people call the art of making paper planes aerogami.

Since paper planes flow (流動) through the air, they can teach scientists and engineers a lot about basic concepts of flight, engineering and aerodynamics （空氣動力學(xué)） In fact, the National Aeronautics and Space Administration (NASA) （美國航天航空局） once sent a paper plane into space on a space shuttle!

If you are wondering how a paper plane would fly in outer space, you might be surprised by the answer. According to scientists, paper planes won't actually fly in outer space. Instead, paper planes would simply float in a straight line and could possibly float forever unless they hit another object!

The Wright brothers also used paper planes to test out their theories about flight before making their first flight. They built a wind tunnel and used paper planes to gain a better understanding of how their plane would operate in the wind.

So just how far can a paper plane fly? On February 28, 2012, former college quarterback Joe Ayoob set the world record for the longest paper plane flight. He threw a paper plane the entire length of a warehouse, setting the record at 226 feet, 10 inches. That broke the old record by 19 feet, 6 inches!

【1】The author thinks making paper planes__________.

A.is difficult activity for childrenB.has its value to flight

C.shows that the Asians are cleverD.is one of the most important discoveries

【2】Why did scientists send a paper plane into outer space?

A.To perform a special task.B.To observe how it would fly.

C.To help astronauts.D.To find some pleasure.

【3】What might make you want to know about a paper plane in outer space?

A.It would fly as we expect.B.It would not move at all.

C.It would hit another object.D.It would float in an unusual way.

【4】Which of the following is true?

A.Leonardo da Vinci created the first paper plane.

B.NASA once flew a paper plane in a space shuttle.

C.The Wright brothers used paper planes to test their flight theories.

D.Joe Ayoob set the world record for the longest paper plane flight at 19 feet, 6 inches.

【5】What is the best title for the passage?

A.The paper plane's influence on flight.
