A.unless B.if

C.until D.though

B

【解析】

試題分析：unless 意為除非……如果不……unless是從屬連詞，引導(dǎo)條件狀語(yǔ)從句，含有否定意義，相當(dāng)于if引導(dǎo)的條件狀語(yǔ)從句的否定形式，unless = if not。 If意為假如，如果。作為連詞，引導(dǎo)條件狀語(yǔ)從句。until直到……時(shí)為止。作連詞的until用于肯定句中，表示主句的動(dòng)作一直持續(xù)到從句動(dòng)作發(fā)生或狀態(tài)出現(xiàn)時(shí)為止。主句的謂語(yǔ)動(dòng)詞必須是持續(xù)動(dòng)詞(非瞬間動(dòng)詞)，如live, wait , last, love, like, stay, work, continue 等。though雖然；盡管，though引導(dǎo)條件狀語(yǔ)從句，放在主句前后均可，有時(shí)還可放在句中。

考點(diǎn)：考查連詞引導(dǎo)的狀語(yǔ)從句

A 15-year-old student who invented a flashlight getting power from the holder's body heat is going home today from California with a big prize and a chance to do further research.

Ann Makosinski was the only Canadian among the four winners at Google's international science competition. Thousands of young scientists from around the world took part in the competition.

Winning the science and technology competition was "a surprise". Ann said, "I think it will have a great influence on my future."

Ann thanked her family for encouraging her interest in science and said that her first toy was a box of transistors(晶體管).

The ideas for the invention came from seeing unwanted batteries and her friend's experience. When Ann visited a friend in the Philippines, she saw the friend couldn't study when it became dark because there was no electricity or light. She saw the need for a flashlight that has no batteries - Hollow Flashlight.

In her project, Ann wrote "I made two flashlights that do not use any batteries or harmful materials. They do not create any noise and will always work. The flashlight needs at least a 5℃ temperature difference between the holder's body and the environment around to produce light."

A video of Ann explaining how she created the flashlight has been watched more than 1.4 million times on the Internet.

Though Ann was successful, she has not made a decision about her career path. Ann hope that she can find a way to join her love of film and science together.

The four winners were chosen from 15 final competitors from eight countries. The competition attracted thousands of students in 120 countries.
