Because the temperature is low and there are not flowers.2. What activities do people in Canada do in spring?
They play “snow” soccer, and many families drive to the countryside on weekends, and go to a sugar bush and make syrup.
3. Why does Jenny love spring?
She loves spring because of all the fun activities and summer follows it.Language points 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.
这部电影和那部电影一样有趣。
(2) Your pen writes as smoothly as mine.
你的钢笔书写起来和我的一样流畅。 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性的。 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。用在否定句中，主句中的谓语可以是延续性的也可以是短暂性动词。? 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.?

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。?一、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”。?
二、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.?
我必须洗洗衣服。?
She has to look after her little sister.
她不得不照顾她的小妹妹。?
I had to do my homework last night.?
昨晚我不得不做作业。?
I think he may have to help his Dad in the garden.?
我想他可能不得不在花园里帮他爸爸。?三、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.?
他没有必要现在做作业。?—Do I have to go there now??
我现在就得去那儿吗？?
—Yes, you do. (No, you don’t have to.)?
是的，你必须去。（不，你不必。）?
We didn’t have to answer the question yesterday.?
昨天我们没有必要回答这个问题。 We ______ listen to the teachers carefully. (必须)
