　　Seeing may be believing，but hearing a sound first may help your sense of sight，according to results of a new study．

　　Researchers at the University of California of San Diego report that people were more accurate at noticing a flash of light when a sound was produced at the same place immediately before the light flashed．

　　“We used a loud sound to catch our participants’（受試者）attention” one of the study’s authors, Dr McDonald， said in an article． During some experiments， the sound occurred at the same location as the flash of light，while at other times it was produced on the opposite side of participants’ field of sight．The 33 participants in the study were more accurate at noticing the flash of light when the sound occurred on the same side，suggesting that sound can help direct visual（視覺的）attention．

　　According to McDonald， his research team plans to continue studying the relationship between sight and sound．

It will be interesting to see， he said，what happens to the ability to pay attention when one of the sense does not work as well as it should，as in a person who is blind of has hearing problems．

　　McDonald also noted that research into the relationship between sight and sound could affect the way we 1ook at peop1e with attention disorder．Traditionally，these people together are considered to have attention prob1em，but in some people the problem may be caused by hearing or sight deficits（缺陷）．

　　“ It could be possible that they cou1d have a deficit in one sense or another，or in relating sight and sound together，” McDonald said．

Research into this area may lead to better treatment for people who have a hard time paying attention．It may be a good idea to take into consideration the relationship between sound and sight when designing warning signals，such as for an airplane pilot．

閱讀理解

　　Many people like the feeling of the gentle wind in spring．Many like to see the falling leaves dancing in the wind in autumn．But sometimes, when the wind becomes a storm, it can be very destructive(毀滅性的)．

　　A series of such storms struck the US last month and caused very serious damage and human pain．

　　Every year, major storms cause many problems around the world．There is nothing people can do to stop these powerful forces of nature．But new techniques are helping scientists to predict(預測)how, when, and where big storms will happen．The more exact scientists' warnings are, the better people can prepare for the storms．

　　Predictions are improving．“We've gotten better over the years, especially the last few years,”says Phil Klotzback, a scientist at an American university．How is a storm formed? Even if scientists know where a storm will happen, winds can suddenly change, carrying the storm to a new direction．“For a hurricane to happen, conditions have to be just right,”Klotzback says．

　　First, the ocean water needs to be warm enough so that it evaporates and rises into the air．As it rises, the vapor(水蒸氣)cools and turns back into liquid．This process gives off heat．This produces energy like an engine that causes winds to increase．It drives the formation(形成)of a hurricane．

　　If wind speeds reach 40 miles per hour, the system is called a“tropical storm”(熱帶風暴), and it gets a name．At 75 miles per hour, it becomes a hurricane．

　　Hurricanes that hit the US start when a thunderstorm forms off the coast of Africa．Storms also develop over tropical waters in other parts of the world．

　　On average, 60 or 70 storms form off Africa every year．About 10 of them get names．There are usually about six hurricanes．Two tend to be very big, with winds of 115 miles per hour or higher．

　　The hurricane season lasts from June to November．Ninety percent of all hurricanes hit in August, September, and October．

(1)

[　　]
A．	form off the coast of Africa and America
B．	travel at 40 miles per hour and get its name

[　　]
A．	begins to move
B．	changes into a gas
C．	becomes hot
D．	gets lost

(3)

Which of the following about the information of a hurricane is in the correct order? a．The ocean water evaporates and goes into the air． b．Heat creates energy and causes winds to increase． c．The vapor cools． d．The ocean water is warm enough． e．The vapor changes back into liquid． f．This course gives out heat．
[　　]
A．	a, d, e, b, c, f
B．	a, b, c, f, d, e
C．	d, a, b, c, e, f
D．	d, a, c, e, f, b

閱讀理解

　　So far, scientists have named about 1.8 million living species(物種), and that’s just a small part of what probably exists on Earth．With so many plants, animals, fungi, and other organisms covering the planet, it can be tough to figure out what type of spider is crawling up your leg or what kind of bird just flew by．

　　A soon-to-be-launched Website might help．An international team of researchers has announced the creation of a Web－based Encyclopedia of Life(EOL)．The project aims to catalogue every species on Earth in a single, easy-to-use reference guide．

　　To get the encyclopedia started, the creators will use information from scientific databases that already exist．And eventually, in special sections of the site, nonscientists with specialized knowledge will join．Gardeners, for example, will be able to record the dates that their flowers first bloom each year．Bird-watchers will be able to input which birds they’ve seen and where．The technology for this kind of tool has only recently become available．

　　As the EOL develops, you might find it useful for school projects．The site will have special pages for kids who are studying ecosystems in their neighborhoods．To make sure the encyclopedia is accurate, scientists will review much of the information added to it．People who visit the site will be able to choose to skip pages that haven’t been reviewed．

　　Another convenient characteristic of the EOL is that you’ll be able to pick the level of detail you see to match your interests, age, and current knowledge．If you wanted to learn about polar bears for a science class report, for example, you could use the“novice”setting to get basic information about the animals．On the“expert”setting, on the other hand．you could get much more detailed information about the history, literature, and exploration of polar bears．

　　It now takes years for scientists to collect all the data they need to describe and analyze species．The creators of the Encyclopedia of Life hope that their new tool will speed that process．

　　Keep an eye on www.eol.org．Pages will begin to go up sometime next year, and you might find them useful for your school reports．The EOL team might have the basics for all 1.8 million entries online as early as 2017．Someday, you might add your own notes．

(1)

What is implied in the last sentence of Paragraph 1?
[　　]
A．	No one can become an expert on spiders and birds．
B．	So many spiders have crawled up your leg
C．	There are far more than 1.8 million living species．
D．	Scientists have named a lot of living species

(2)

Which of the following statements is TRUE?
[　　]
A．	You can find information of all living species online in 2017．
B．	Nonscientists will be able to add their own notes to the website．
C．	The kids preparing school reports can not have access to the informat’0 n’
D．	You are not free to choose the amount of detailed information．

(3)

What does the underlined word“novice”probably mean in Paragraph 5?
[　　]
A．	Beginner．
B．	Specialist．
C．	Scientist．
D．	Pupil．

(4)

Who are the intended readers of this passage?
[　　]
A．	Students．
B．	Researchers．
C．	Bird watchers or Gardeners．
D．	People in general

(5)

What is the best title for the passage?
[　　]
A．	Exploring Polar Bears
B．	Visit Our Website Now
C．	How to Do School Projects
D．	E-book of Life．
