Free talk
I like the vibrant colours of spring most. The blooming flowers, green trees, and clear blue sky make the world full of life.
“The spring city” usually refers to Kunming in China. It has a mild (温和的) climate all year round, with flowers blooming and greenery (绿色植物) everywhere, so it’s called “the spring city”.
Reading
When we talk about spring, we think of a season of warm weather and fresh air. We also think of new life, green plants, and budding trees all around us. Spring is short in many places around the world. But in my hometown, it feels like spring nearly all year round.
The weather here is neither too hot nor too cold. The average temperature in winter is 15℃ . In summer, the average temperature is 24℃ . While the sun is shining, the temperature remains pleasant. The city gets about 2,250 hours of sunshine and about 1,000 millimetres of rain every year. Because the weather is spring-like, you can find hundreds of beautiful flowers and trees all year round.
There are many famous scenic spots in my hometown. The Stone Forest is a must-see for tourists from home and abroad. There are many special rocks that look like tall stone trees. The Dianchi Lake is the biggest in Yunnan Province. You can enjoy the beauty of the area and go boating or take a walk by the water.
Can you guess the name of my hometown Yes, it’s Kunming — the Spring City. Welcome to my hometown. When you visit, you will feel our warmth and friendliness, just like spring!

An adverbial clause is a type of dependent clause that functions as an adverb in a sentence. We use when and while to show time, and because to show the reason for an event.
Grammar focus
时间状语从句
1. when 表示“当……的时候”。引导的从句动作可以是延续性动词(如 study, wait) 或非延续性动词(如 start, stop) ，主句和从句的动作可以同时发生，也可以先后发生。
e.g. When I got to the park, my brother was playing basketball with his friends. 当我到公园的时候，我哥哥正在跟他的朋友们打篮球。
I loved history when I was at school. 我上学时喜欢历史。
时间状语从句用来表示主句动作或状态发生的时间。
一、时间状语从句的引导词
2. while 表示“在……期间”。引导的从句动作必须是延续性动词(用进行时态) ，强调主句和从句的动作同时发生。
e.g. While I was reading, my sister came in and passed me some fruit.
当我正在读书的时候，我妹妹进来，递给我一些水果。
3. as 表示“随着……；一边……一边……”。强调主句和从句的动作同时发生或一个动作随着另一个动作的变化而变化。
e.g. As time goes by, we grow older.
随着时间的推移，我们长大了。
4. before/after 表示“在……之前/ 在……之后”。强调动作的先后顺序，主句和从句时态根据实际时间判断。
e.g. Before I made a decision, I thought carefully about it.
在做出决定之前，我仔细考虑过。
After he finished his work, he went home.
他完成工作后就回家了。
5. until/till 表示“直到……”。
(1) 肯定句：主句动词是延续性动词，表示动作“持续到until/till 时间点为止”。
(2) 否定句(not...until) ：主句动词是非延续性动词，表示“直到……才……”。
e.g. I’ll wait outside until the meeting’s over.
我要在外面等到会议结束。
I won’t leave until/till you come back.
我直到你回来才离开。
6. as soon as 表示“一…… 就……”。强调动作紧接着发生，主句用将来时，从句用一般现在时表将来。
e.g. I will tell him the news as soon as he arrives.
他一到，我就告诉他这个消息。
1. 若主句用一般将来时，从句用一般现在时(主将从现) 。当主句表示将来的动作或状态时，从句要用一般现在时表示将来。
e.g. I will call you when I get home. 我到家的时候会给你打电话。
二、时间状语从句的时态
2. 若主句用一般过去时，从句根据情况使用过去的相应时态。当主句表示现在的情况时，从句可以根据实际情况使用不同的时态。
e.g. While I was walking, it rained suddenly.
我正在走路时，突然下雨了。
When he is free, he often goes to the library.
当他有空的时候，他经常去图书馆。
原因状语从句 (Adverbial clauses of cause)
原因状语从句是用于说明主句原因的从句类型。
1. because引导的原因状语从句一般放于主句的后面，because从句位于句首时要用逗号分开，放在句末时，可不用逗号分开。because表示直接原因， 语气最强， 最适合回答why引导的疑问句。
e.g. I do it because I like it. 我做这件事是因为我喜欢。
Because she was ill, she didn't go to school.
因为她生病了，所以没去上学。
2. as引导原因状语从句时表示附带说明的“双方已知的原因”， 语气比because弱， 较为正式， 位置较为灵活(常放于主句之前)。
e.g. As you are tired, you had better rest.
既然累了， 你最好休息一下。
I went to bed early, as I was exhausted.
我睡得早， 因为我已筋疲力尽了。
3. for在句子中主要作为并列连词 ，引导原因状语从句与because等从属连词不同，for引导的原因并非直接导致主句行为的核心因素，而是对主句结果的补充性解释或附带说明，语气较弱，通常不用于回答"why"的提问。 必须放在主句之后，与主句用逗号隔开，不可置于句首。
e.g. The ground is wet, for it rained last night.
地面是湿的，因为昨晚下雨了。
Circle the correct words.
A They didn't go to the beach today (because/but) it was raining.
B Wang Mei called me (while/because) I was writing an email.
C People eat pears (so/when) Jingzhe comes.
D A heavy rain fell (because/while) they were asleep.

Language points

feel like 意为“感觉像是；想要”，后接名词、动名词或宾语从句。
常见用法：

(3) feel like+ 从句 感觉像是……
e.g. She feels like a winner after finishing the race.

辨析：feel like 与would like
feel like 都可以用来表达“愿望或想要做某事” 后跟sth. 或doing sth.， 表示“ 想要做某事”或“感觉好像……”，更强调一种主观的感受或欲望。
would like 后跟sth. 或to do sth.， 表示“ 想要做某事”或“希望某事发生”，通常用于表达一种礼貌的请求或愿望，适用于正式场合。
e.g. I feel like I’ve forgotten something important.

all year round 全年；一年到头
e.g. The museum is open all year round.
博物馆全年开放。
2. The weather here is neither too hot nor too cold.
这里的天气既不太热也不太冷。
neither 既可作副词，意为“也不”，表示前面的否定情况也适用于另外一个人或物，并且句子用倒装语序；还可作代词，意为“两者都不”。
neither... nor... 连接两个并列的主语时，谓语动词的单复数形式常和邻近的主语保持一致，即“就近原则”。
neither of... ……中的两者都不
e.g. She doesn’t want to go to the zoo, and neither do I.
她不想去动物园，我也不想。
Neither my sister nor my brother likes to play video games.
我的姐姐和弟弟都不喜欢玩电子游戏。
Neither of the two shirts fits me. 这两件衬衫都不适合我。
3. While the sun is shining, the temperature remains pleasant.
shine 作动词表示“发光；照耀”时，其过去式、过去分词都是shone，现在分词是shining。
shine 还可作名词，意为“光亮；光泽”，通常用于描述某物的外观或效果。
相关词形：(1) shiny adj. 光亮的；反光的
(2) sunshine n. 阳光；幸福
e.g. The sun shines brightly in the sky. 太阳在天空中明亮地照耀。
Her eyes were shining with excitement. 她兴奋得两眼放光。

remain 的一词多义：
(1) “保持(某种状态) ”，后接形容词、名词、介词短语等，强调状态持续不变。
(2) “停留；留在某处”，后接地点状语(如介词短语) ，指“待在某个地方不离开”。
(3) “剩余；遗留”，主语通常是物，指“剩下未被使用或处理”。
e.g. He remained calm when facing difficulties.
面对困难时，他保持冷静。
She remained in the classroom to finish her homework.
她留在教室里完成她的家庭作业。
Only a few seats remained in the cinema.
电影院里只剩下几个座位了。
4. Because the weather is spring-like, you can find hundreds of beautiful flowers and trees all year round.
because 引导的原因状语从句用于说明某个动作或状态的原因，可以用于各种时态和语境。
because 从句可以与“because of + 名词/ 名词短语”互换。
e.g. He failed the exam because he didn’t study.
= He failed the exam because of not studying.
他考试不及格，因为(他) 没学习。
辨析：because 与because of
because 意为“因为”，作连词，引导原因状语从句，可用于回答why 提出的问题。
because of 意为“由于”，后面接名词(短语) 、代词、动名词或what 引导的名词性从句等，不能接一个可独立存在的句子。

因为我父母很忙，我经常帮忙做家务。

hundred num. 一百；许多。用法总结：
(1) 表示具体数字“几百”时，用“具体数字+ hundred +可数名词复数”。
(2) 表示“不具体的数量”，强调数量多时，用“hundreds of + 可数名词复数”。hundreds of 意为“大量的；数以百计的”。
(3) 前有a few, several 等词修饰时，要用单数形式。
与hundred 类似用法的词还有thousand, million, billion 等。thousands of 数以千计的；millions of 数以百万计的；billions of 数以十亿计的
