一、非限制性定语从句
1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，例如：
This is the house which we bought last month.这是我们上个月买的那幢房子。（限制性）
The house, which we bought last month, is very nice.这幢房子很漂亮，是我们上个月买的。（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。
3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。
说明：关系代词that和关系副词why不能引导非限制性定语从句。

二、反意疑问句：
（1） 反意疑问句是由陈述句以及其后面的简略疑问句构成，前一部分为陈述句，后一部分由助动词或情态动词 + 主语(人称代词)构成，可表示真实的疑问。也可以表示说话者的某种倾向，强调或反问
It’s raining , isn’t it?
(2) 反意疑问句的前半部分陈述句是肯定的，则疑问部分为否定形式；反意疑问句的前半部分陈述句中若为否定，则疑问部分为肯定形式。
(3) 前半部分陈述句含有hardly, never, seldom, few, little等词时，疑问部分为肯定形式。
We hardly know each other, do we?
There is little left for us to do, there is?
(4) 反意疑问句的前半部分陈述句中若使用了助动词，情态动词或 be 动词，后半部分先重复这些动词，然后 + not +主语，构成简略句
You can read this , can’t you?
She should have a rest , shouldn’t she?
(5) 如果反意疑问句前半部分肯定句中谓语动词是实意动词，后半部分一般由 didn’t / doesn’t 和didn’t + 主语构成
We need some salad too , don’t we?
He looks like his father , doesn’t he?
(6) 祈使句后面的反意疑问句是will you/shall we?
Let’s stop quarreling and get down to business, shall we?
Come over to my house, will you?

With the long days of summer 1 and kids heading back to school, it seems that exercise should become easier to do instead of harder.

4 of waiting for the 'right' time, why not start now? Getting exercise firmly established makes it easier for it to 5 a priority（要优先做的事） for you.

- Plan what you'll do and what you'll need to do it--e.g., if you're going to the gym you'll need to have your gym bag ready and snacks/meals ready to go. Prepare as much as you can beforehand for smoother workouts.
- Look for creative ways to be active. One person who jogs around the soccer field at her son's practices. There’s another who rides bikes with his daughter every morning before school. Integrating(结合)exercise with other activities is one way to stay 9 and still keep up with responsibilities.
- Set up a basic home gym. Even if you prefer a health club, having some basic equipment 10 as well as a few quality workout videos means you're always ready for a workout. Think resistance tubes or bands, an exercise ball and some dumbbells.
