参考范文:
Today we carried out an experiment,whose aim was to find out
if there is a change in weight after aluminium is heated. To carry out
the experiment,we prepared the following equipment:pieces of
aluminium,a Bunsen burner,a balance,a crucible and a pair of
tongs.
The stages were as follows. First, we put the pieces of
aluminium in the crucible. Then we put the crucible on the balance
and weighed it. Next,we lighted the Bunsen burner. After that,we
held the crucible with aluminium in it over the Bunsen flame.
Finally,we put the crucible with the aluminium in it on the balance
and weighed it again. We found it weighed a little more than before.
We drew the conclusion that there is a change in weight after
aluminium is heated.

参考范文:
To find out whether orange juice and oil dissolve in water,we
did an experiment in the chemistry class.
Firstly,we prepared the following apparatus:test tubes and
spoons. Secondly,pour water into two test tubes. Make sure the water
level is equal in either tube. Put a spoonful of orange juice into one
tube,and a spoonful of oil into the other. Finally,leave the tubes for
five minutes.
Five minutes later,the orange juice has dissolved. However,
the oil remains on the surface.
Then we draw the conclusion that the orange juice dissolves in
water quickly while the oil is hard to dissolve in water.

听力技巧点拨(三)——如何突破应用类独白
题型解读
高考英语听力测试最后一段一般为独白,主要
考查考生对短文听力的把握能力,所以对考生的记
忆理解能力要求较高。题材涉及历史、文化、新闻
时事和人物等方面,它既要求考生掌握材料的主旨
大意,也要求获取有效的事实细节,并根据材料进
行简单的推理。
高考听力中的应用类文章主要指新闻报道、景
点介绍、旅行计划的讲解、电台的采访等。命题主
要考查:
(1)根据听力内容或背景效果,推测相关的具
体内容;
(2)在理解大意的基础上推测说话人的意图、
观点和态度等。
在判断推理的过程中要注意以下
!(!
几个问题:防止以偏概全、防止断章取义、防止似是
而非。
技巧点拨
一段独白配置3 ~ 4道问题,有的针对独白的
细节,有的针对独白的整体把握。独白的难度比对
话大,首先是因为独白的信息量比较大(每篇独白
大约150 ~ 300个词),是对话的几倍甚至十几倍。
其次,由于独白具有鲜明的英文写作的特点,在语
法和句子结构的难度上都有所加深。同时独白的
内容广泛,题材丰富,所以要求应试者不仅要有较
高的理解能力,而且要熟悉英文写作的特点,有较
宽的知识面。
【典题印证】

【材料复现】
W:Here is a piece of news for bird lovers. Scientists
have painted a long road red,yellow,and white.
They hope to discourage the seabirds from
wandering onto the highway.“The area is home to
large crowds of birds that come to stay for the
season. Young birds are often attracted to the warm
road surface and get killed by the traffic,”biology
student Hannah tells the broadcaster. The
youngsters feathers are brown in color. The dark
colored road surface makes the youngsters hard to
be noticed. As the number of tourists has grown,
so has the amount of traffic on the roads. Biologist
Kristin says the plan is to see how the birds
respond to the multicolored road this summer.
And if it works,the idea could spread to other
parts of the country.
【解题思路】
18. B 事实细节题。根据“Scientists have painted a
long road red,yellow,and white.”可知,科学家
们将道路粉刷成了红色、黄色和白色。故选B。
19. A 事实细节题。根据“Young birds are often
attracted to the warm road surface and get killed
by the traffic”可知,小鸟们经常被温暖的路面
吸引。故选A。
20. C 推理判断题。根据上下文“Young birds are
often attracted to the warm road surface and get
killed by the traffic”和“Biologist Kristin says the
plan is to see how the birds respond to the multi
colored road this summer.”可知,科学家们的试
验是为了阻止鸟儿被杀害。故选C
。
