重点探究
Dear Wang Mei,
It isn’t snowing today, but there is still snow on the grass. In Edmonton, the weather in March can be cold and snowy or warm and sunny. It’s a little wild. The temperature can be as low as -15℃, but it can also reach 15 ℃. Still, sometimes it snows in April and May! The temperature drops below zero on those snowy days. We probably won’t see any flowers until May or June!
THINK ABOUT IT
What clothes do you wear in spring
What interesting things do you see in spring
After school today, we played outside. We played “snow” soccer. We had to wear our jackets and boots, but it was fun. Danny fell into the snow. Maybe next month we will play in our shorts and T-shirts!
I like the Chinese name for winter jasmine. It’s interesting. Here, we have Groundhog Day on February 2 for the coming of spring. In spring, many families drive to the countryside on weekends. A popular place to go is sugar bush, it's so much fun to make syrup.
I love spring because of all the fun activities. Also, summer follows it!
Talk to you soon!
Jenny
Culture Tip
Groundhog Day is on February 2. On that day, a small animal called a groundhog comes out of a hole in the ground. If it sees its shadow, then spring won’t come for another 6weeks. But if the groundhog does not see its shadow, then spring is very close. How does a groundhog know It doesn’t! It’s just a very old tradition in North America.

3. Read the passage and fill in the blanks with the sentences below.
拓展提升
1. The temperature can be as low as -15℃.
as...as意为“和……一样”，表示同级的比较。
使用时要注意第一个as为副词，第二个as为连词。
其基本结构为：as+ adj./ adv. +as。例如：
1) This film is as interesting as that one.
2) Your pen writes as smoothly as mine.
其否定式为not as/so +adj./ adv. +as。例如：
This dictionary is not as/so useful as you think.
这本字典不如你想象的那样有用。
若有修饰成分，如twice, three times, half, a quarter等，
则须置于第一个as之前。例如：
Your bag is twice as expensive as mine.
你的袋子比我的贵一倍。
2. We probably won’t see any flowers until May or June!
until “直到”，表示某一种行为一直持续到某一时间。用在肯定句中，句子的谓语动词必须是可延续的。 not...until...“直到……才......”表示直到某一时间，某一行为才发生，之前该行为并没有发生。在否定句中，主句中的谓语可延续也可短暂。
1)I studied English until 9 o’clock last night.
我咋晚学英语一直学到9点钟。(表示9点前一直在学)
2)I did not study English until 9 o’clock last night.
我咋晚直到9点钟才学英语。(表示9点才开始学)
3)I waited for five hours until it was dark. I had to give it up.
4)I didn’t go to sleep until 11 o’clock.
not until 还可以用于强调句中，也可以放在句首，
句子要采用部分倒装。
5) It was not until he came back that I went to sleep
Not until he came back did I go to sleep.
3. We had to wear our jackets and boots…
have to 是一个比较特殊的情态短语，虽然也具有情态动词的功能，但却与其他的情态动词不同。它有人称、数和时态的变化，其否定式和疑问式的构成方式也与情态动词不一样。同学们在使用have to 时必须弄清它的真面目，否则容易出错。
1). have to 与其他情态动词一样也是后接动词原形，表示外
界的强制作用，强调被迫性。含有不情愿的色彩，常译为 “必须，不得不”。
2). have to 可用于多种时态，而且不同时态使用不同的形式：
一般现在时中，主语为第三人称单数时用has to ; 一般过去
时中，用 had to, have to 还可以用在其他的情态动词之后。
例如：
I have to do some washing.
She has to look after her little sister.
I had to do my homework last night.
I think he may have to help his Dad in the garden.
3). have to 的否定式和疑问式一般要借用助动词do的适当形式构成。have to 的否定式是don’t have to； has to 的否定式是doesn’t have to；had to 的否定式是didn’t have to。have to的疑问式同样也借用助动词do的相应形式构成。
例如：
He doesn’t have to do the homework now.
—Do I have to go there now
—Yes, you do. (No, you don’t have to.)
We didn’t have to answer the question yesterday.
【辨析】have to, must
have to与 must均有“必须”的意思,但must强调人主观认为必须做某事,而have to强调客观情况迫使人不得不做某事;且must只用于一般现在时中,没有人称和数的变化,而have to可用于多种时态中,并且有人称和数的变化。
We must go to school on time.
She has to look after her baby at home.
