learning & Speaking
1.Water in a flood runs much faster than usual and takes away everything in its way.
译文：洪水中的水比平时流得快得多，带走了沿途的一切。
解析：in one’s way 意为 “挡路；妨碍；碍事”，侧重物理上挡道或抽象上造成阻碍。
例句拓展：Your bike is in my way. Could you move it a little
你的自行车挡着我的路了，能把它挪一下吗？
His shyness gets in the way of his communication.
他的腼腆阻碍了他的交流。
短语 含义 例句
in one’s way to 在某人去什么的路上 I met a dog on my way to school.在我上学路上遇到了一只狗。
by the way 顺便一提 By the way, do you know the meaning of the phrase "in one’s way" （顺便问一下，你知道短语 “in one’s way” 的意思吗？）
in the way 挡路 The big stone is in the way, so we can’t walk through the road.（这块大石头挡路了，我们没法走过这条路。）
拓展
Don’t worry. I will help you when I am ______.
A. in my way
B. on my way to home
C. on my way home
D. in my way to school
答案：C
解析：正确短语是 on one’s way to… 在某人去…… 的路上
home 是地点副词，前面不加 to，所以是 on my way home
in one’s way 意为 “挡路、妨碍”，放在这里句意不通。

2.A sudden rise of temperature is a heatwave and the temperature in the central area always rises the fastest.
（1）名词化结构
a sudden rise of temperature 中，rise 由动词（上升）转化为名词（上升；升高），sudden 作定语修饰 rise，表示 “温度的突然上升”。
（2）副词最高级
the fastest 是 fast 的副词最高级，修饰动词 rises，表示 “上升得最快”；副词最高级前的 the 可省略，但此处为了强调，保留了 the。
用词的适当形式填空
1.Look! The temperature __________ (rise) quickly.
2.A sudden __________ (rise) of temperature is very common in summer.
3.The sun __________ (rise) in the east every day.
1.is rising
2.rise
3.rises
Of all the cities here, the temperature rises ______ in the center.
A. fast
B. faster
C. the fastest
D. the faster
答案：C
解析：句中有范围 Of all the cities（在所有城市中），要用最高级，fast 的最高级是 the fastest。

3.In a typhoon, strong wind mixes with heavy rainfall. It hits everything harder by the sea than...
译文：台风天气中，强风与暴雨交织。海边的风力比…… 更猛烈，冲击着一切事物。
mixes with 是固定短语，意为 “与…… 混合 / 相伴”，主语 strong wind 为不可数名词，谓语动词 mix 用第三人称单数形式 mixes。
选择填空
In a typhoon, strong wind ______ heavy rainfall.
A. takes away B. mixes with C. burns down D. rises in
答案：B
解析：句意：“在台风中，强风______暴雨。”A. takes away（带走）；B. mixes with（与…… 混合 / 相伴）；C. burns down（烧毁）；D. rises in（在…… 中出现）。台风的典型特征是强风伴随暴雨，“mixes with” 符合语境，故选 B。
4. Prepare free food and water and offer help to those in need.
in need意为“需要（帮助、支持等）的；处于困境中的”，常作后置定语或表语，用来描述人、群体或抽象事物的处境语法特点：后面不直接接宾语。
例句：We should care for the elderly in need.（我们应该关爱有困难的老年人。）
类似的表达有：
短语 含义
in danger 处于危险中（的）
in trouble 处于困境中（的）
in pain 处于痛苦中（的）
in surprise 惊讶地；处于惊讶中（的）
in silence 沉默地；处于沉默中（的）
in progress 正在进行中（的）
We should try our best to help people ________.
A. in need B. in the need C. on need D. at need
答案：A
解析：固定短语 in need 表示 “处于困境中的；需要帮助的”，可直接作后置定语修饰 people，无需加冠词。
