【題目】閱讀下面短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項。

What is colour? Why do some of the things around us look red, some green, others blue?

Colours are really made by reflected (反射) light．We see colour because most of the things reflect light．Something is red, for it reflects most of the red light．In the same way, if something is green, it reflects most of the green light．If something reflects all light, it is white．If it doesn’t reflect any light, it is black．

Some of the light is reflected and some is taken in (吸收) and turned into heat．The darker the colour is, the less light is reflected, the more light is taken in．So dark-coloured clothes are warmer in the sun than light-coloured clothes．

【1】When something reflects light, we can _______ ．

A． see its colour

B． see its heat

C． not see its colour

D． see no thing

【2】The dark-coloured clothes are warm because _________ is taken in．

A． more light

B． less light

C． more colour

D． less colour

【3】In summer ________ make people feel cool．

A． dark-coloured clothes

B． red-coloured clothes

C． green-coloured clothes

D． light-coloured clothes

【答案】

【1】A

【2】A

【3】D

【解析】

【1】細節(jié)理解題。由第二段第一、二句：Colours are really made by reflected (反射) light．We see colour because most of the things reflect light．可知光的反射而使人們看到顏色，故選A；

【2】推理判斷題。由短文可知，黑衣服吸收所有光，因此更暖和，故選A；

【3】推理判斷題。根據短文，深色衣服吸收光線，容易變熱；淺色衣服反射更多的光線，較涼，故選D。

【題目】閱讀短文，下列問題
B
At the moment, high school students in the state of Philadelphia, USA, can wear their own clothes. However, next year the high schools must do one of the following:
●Either make students buy school uniforms (in other words, all students must wear the same uniforms)
●Or say which colors must be worn, but let students buy their own clothes in these colors
A survey made at Central High School, Philadelphia, showed that most of the students didn't think that wearing school uniforms was a good idea.
Rachel didn't like the idea of a uniform in the slightest. “It makes us look like prisoners (囚犯). Everyone's different, so why is the school trying to make us all the same?”
Sandra was wearing a brightly-colored shirt with her jeans. “No one else wears a shirt like mine, ” she said. “I'm the only one, and I like that. I can understand that the school needs a dress code (準則). It's a problem if students come to school with their shirts open. We all understand that, but no one wants a uniform. Even my mum thinks it's silly.”
Only one student, Ben, said he didn't mind wearing a school uniform. He said, “I used to wear a school uniform when I lived in Australia for a year. It wasn't so bad. You can wear a uniform and still be tidy. We used to wear grey trousers, a round-necked shirt and a jacket in blue or green. It wasn't a problem.”

A.don't allow students to wear their own clothes at present

A.one third of the students thought wearing school uniforms was a good idea
B.none of the students thought wearing school uniforms was a good idea
C.not all students were against wearing school uniforms
D.only one student was against wearing school uniforms
（3）In Rachel's opinion, ________.
A.uniforms make students look ugly
B.students should wear uniforms in the same way
C.wearing a school uniform isn't a problem
D.some colors must be worn at school
（4）When Ben lived in Australia, he used to wear ________ in the school.
A.a brightly-colored shirt and jeans
B.blue or green trousers and a round-necked jacket
C.clothes that no one else wore
D.a tidy school uniform
（5）What does the underlined word “that” mean in the sixth paragraph？
