【题目】阅读理解
You might make a disgusted face when you notice that the person waiting in their car at the red light next to you is picking their nose,but admit it,you do it too.And while it might be the natural option when there isn't a box of tissues around,it can be bad for you.The main reasons people feel the need to pick their nose is to clear it of dried liquid,stop an itch(痒),or just because it feels good.Boogers(鼻屎)form when dried liquid and cilia,the tiny hairs that line the nostrils(鼻孔),trap the dust,dirt,and other things.When boogers build up in your nose,it can be uncomfortable,and sometimes just blowing into a tissue doesn't do the trick.
Otolaryngologist Erich P.Voigt, MD ,told Business Insider that picking your nose can cause injuries and bleeding within your nostrils.That's not terribly damaging,but when the bacteria from your hands get into your body,it can cause a cold and flu.So doctors strongly suggest not picking the nose.
If dry winter air is causing the dirty liquid to harden in your nostrils,making you want to pick,consider damping the air at home,or taking a steam shower to soften things up in there.
Children, who are most famous for having a finger up their nose,sometimes don't realize how much injury they're causing,and sometimes it.can lead to nose bleeds.
So, next time you go to pick your nose,think about how many bacteria are on your hands and in your boogers, and maybe reach for a tissue instead.Even if you 're alone,and not waiting for the light to turn green,please,use a tissue.

【题目】Radar is an electronic device that detects planes, ships, coastlines, landmarks, and even storm clouds. The name radar comes from the first letters of the words radio direction and ranging. As the human eye uses light waves to see, radar “sees” with radio waves. Without radar, planes could not land safely in bad weather and ships could not move safely in thick fog. 1

In the 1800s it was discovered that radio waves could be reflected from objects. But scientists did not make great advances in radar research until the 1930s, when the world was threatened by war.2 It has been used widely in almost every conflict since then.

Echoes make it possible for radar to work. When a beam of radio waves is sent out, it strikes on an object and returns an echo. This echo is picked up by radar and recorded on a screen similar to television screen. On the screen an observer sees a flash, or a blip, that shows the direction and distance of the object. 3

Airport control towers use radar to guide planes in for safe landings. Almost all large ships depend on radar to prevent collisions with icebergs or other ships.4Weather forecasters “see” the size, direction, and speed of storms on radar screens. Astronomers can even use radar to measure accurately the distance to the moon. Thus, the device has generated major advancements.

5Huge radar antennas have been installed all over the United States. They guard us against possible enemy attacks. We have ballistic—missiles (战略导弹)warning systems that can alert us to attacks when missiles are more than 1,000 miles away. Other radar systems warn us against enemy aircraft and even spying space satellites.

A. Police track speeders in radar-equipped cars.

B. These measurements are now highly accurate.

C. The device can be used in a wide range of fields.

D. It is therefore especially valuable to shippers and travelers.

E. During World War II many countries used radar effectively.

F. Today radar is used by commercial airliners and weather forecasters.

G. Strengthening national defense is one of radar’s most important functions.

【题目】The Republic of Vanuatu is an island nation located in the South Pacific Ocean. It was one of the poorest nations in the region. Within the last five years, however, it has become a hot spot for adventure travelers. In 2006 it was voted the happiest place on Earth. The reason is not that Vanuatu are the richest but that Vanuatu has white-sand islands, clear waters, the world’s most accessible live volcano, great diving and food that grows faster than it can be picked.

With a population of about 221,000, Vanuatu has 113 languages, which is a result of 3,000 years of immigration from many Pacific countries. There are three official languages: English, French, and Bislama. Bislama developed from South Pacific English, a simplified language that traders and other foreigners used it to communicate with speakers of the many local languages.

Most of the islands are mountainous and of volcanic origin. There are several active volcanoes in Vanuatu, including Yasur on the island of Tanna, one of the world’s most accessible volcanoes. If you’ve ever fancied getting close to a volcano, here’s your chance.

Vanuatu Post’s Underwater Post Office has quickly become one of the busiest post offices for postcards in the world! Visitors from around the world want to experience the world’s first under- water post office. The Post Office is only 50 meters offshore and at just three meters below the surface, very appealing to the young and young at heart. Since opening in 2003, the underwater post office has received about 100,000 visitors. They have posted one of the waterproof(防水的)postcards available in Vanuatu; these cards are collected regularly by one of Vanuatu Post’s four trained divers. The underwater branch is manned daily for usually about an hour, longer with demand.
