语法感知
感知以下课文原句，补全方框下的小题

(1)However，during this period，it can be easy for some of them to form bad habits.
(2)To prevent harmful habits like these from dominating a teenager’s life is essential.
(3)To change bad habits is never easy.
(4)After all，it is not easy to break bad habits.

1．以上句子中动词不定式都是作主语。
2．句(1)和句(4)中it作形式主语，真正的主语是后面的动词不定式。
语法精析
动词不定式作主语
一、基本用法
动词不定式作主语时，谓语动词用单数。
To look after these naughty boys is really difficult.
照看这些淘气的男孩真的很难。
为了避免头重脚轻，常用it作形式主语放在句首，作主语的不定式常置于句末。
It would be better for you togo there.
你还是去那里的好。
注意：1.若要说明不定式表示的动作的发出者的话，要在不定式前加for引起的短语，构成“for＋名词(或代词宾格)＋不定式”短语，这一短语被称为不定式的复合结构。
2．在“It is＋adj.＋不定式复合结构”句型中，当其中的形容词是说明逻辑主语的性质、品质时，要由of引出逻辑主语，不能用for。这类形容词主要有clever，foolish，kind，nice，polite，silly，stupid，wise等。
It’s easy for him to work out this math problem.
对他来说解出这道数学题很容易。
It was careless of him to make such a mistake.
＝He was careless to make such a mistake.
出了这样的错误，他太粗心了。
二、动词不定式和动名词作主语的异同点
1．动名词和不定式作主语的相同点
(1)不定式和动名词作主语时，常常为了保持句子的平衡，用it来作形式主语，如：
It is not easy tolearn English well.学好英语不容易。
It is no use asking him for help.向他求助是没有用的。
(2)如果主语用了不定式，表语和宾语也要用不定式；主语用了动名词，表语和宾语也要用动名词，这在英语中称为对称性，如：
Tosee is tobelieve.＝ Seeing is believing.眼见为实。
It is better tostay home than togo out.
待在家里比出去要好。
2．动名词和不定式作主语的不同点
(1)不定式作主语常表示具体的某一动作；表示泛指或一般的抽象的概念时，多用动名词。
Walking is a good form of exercise for both young and old.
散步是一种老幼皆宜的很好的运动形式。
(2)在“It ＋be＋no use(good/help/need) ”之后常用动名词作主语，而少用不定式。
It is no use crying over the split milk.覆水难收。
It is no help taking this medicine.服用这种药没有用。
注意：如果该句型中用了for引出不定式的逻辑主语，就只能用不定式。
It is no good for us todo that exercise.
我们做那种练习没有好处。
(3)不定式可以和when，where，how，what，whether等连用，在句子中作主语、宾语和表语，而动名词则不能。
Wheretoput the box seems hard to decide.
很难决定把这个箱子放在哪里。
Whethertodo it hasn’t been decided.
是否做这件事还没定下来。

Ⅰ.单句语法填空

7．Whether tohold(hold) a party this weekend hasn’t been known yet.
8．The boy was so young that he couldn’t decide which one tochoose(choose)．

语篇解读　这是一篇说明文。给人建议是一门艺术，本文就如何给出建议提出了几个注意事项。

9．答案　achieving
解析　考查非谓语动词。此处in用作介词，后接动名词作宾语。
10．答案　judg(e)ment
解析　考查词性转换。冠词后接名词。judg(e)ment n．判断。
11．答案　taken
解析　考查状语从句的省略。完整句为：if it is taken in the right spirit。故填taken。
12．答案　is offered
解析　考查动词的时态和语态。offer与其逻辑主语advice之间为被动关系，由上下文语境可知，文章主体时态是一般现在时，故用一般现在时的被动语态。
13．答案　It
解析　句中的it作形式主语，真正的主语为后边的that从句，首字母大写。故填It。
14．答案　giving
解析　考查非谓语动词。此处是动名词作主语。
15．答案　relaxed
解析　考查词性转换。此处作表语，形容人的状态，故填relaxed。
16．答案　but
解析　考查连词的用法。根据上文的意思可知，此处表示转折，故用but。
17．答案　like
解析　考查介词的用法。此处句意为“在其他一些重要问题上，比如保持一种关系或者未来的计划上，需要谨慎地给出建议等”。
18．答案　cautiously
解析　考查词性转换。此处修饰动词，故用副词形式。

Ⅲ.阅读理解

The health benefits of sleep are both varied and well known.We all need to have enough sleep so as to be able to function well on both mental and physical tasks.Sleep is probably the best beauty treatment available to a person，allowing you to look younger overnight.This is probably the most superficial(表面的) benefit of sleep.The other benefits are incredibly important.
The amount of sleep that is required varies from one person to another and in many cases one person is at risk of not getting enough sleep.It is all too easy to settle into a habit that doesn’t really suit you when your family requires less sleep than you.They may well try to get up quietly and leave you resting a little longer.If they are successful in slipping(溜) out of the room and you remain in the same state of sleep then you are very lucky.Many people find themselves being disturbed by either sound or movement and then it can be difficult to return to sleep.
The fact is that whatever your reasons are for settling for less sleep than what is ideal for you，it is important to deal with your situation.Sleep is very important.Failing to get enough sleep is very costly to your health.
Many people have trouble getting to sleep.Their minds run on overtime or they become overtired.Perhaps you have simply gotten out of the habit of sleeping well.If this is the case then meditation(冥想) or hypnosis(催眠状态) can be very helpful.
Hypnosis is a natural state of relaxation and is in fact the state between being awake and asleep.When learning to use hypnosis you can also teach yourself how to relax，let go of bad thoughts and prepare yourself naturally for sleep.It is natural and easy.Simply by listening to hypnotic songs you can train your mind to expect to sleep and return to your natural sleep patterns.

Jim Denevan is an amazing artist whose work is admired by all，but owned by none—that’s because all of Jim’s art is created on an unusual canvas—the soft sand.He sometimes spends days working on a piece，only to see it washed away by the sea or a storm and that is just the way he likes it.
Denevan discovered his artistic talents about ten years ago，when he was wandering aimlessly on the beach with a stick.He ended up drawing a 12footlong fish.Since then，Jim has traveled over 1,800 miles while creating over 600 pieces of sand art.
Over the years，his drawings have become bigger，but the tools he uses haven’t changed—All he needs is a stick，a garden rake(耙) and most importantly，his lively imagination!
Just like any good artist，Jim is quite particular about the “quality” of his canvas，sometimes walking for miles，in search of perfect sand.His latest piece of work，which is also the world’s largest freelance drawing(自由绘画)，was created in the desert sands of Nevada.It took Jim three trips，eight days and over 100 miles of walking to create this 3mile work of art.It took the storm just one night to destroy it! However，Jim says he actually enjoys watching the waves or rain wash his paintings away.
Jim’s art has become very popular over the years and was even the topic of a documentary named “Sandman” in 2005.Jim Denevan is not just about art in the sand—he is also an excellent chef and founder of an organization called “Outstanding in the Field”，whose motto is to celebrate food at its source.Accordingly，group dining events are held outdoors on farms，with the diners being treated to a delicious meal.The events，which are held in different farms throughout America，are always sold out the minute the schedule is announced.

语篇解读　Jim Denevan是一个了不起的艺术家，但没有一个人拥有他的作品，那是因为他所有的艺术是创作在一个不寻常的画布上——柔软的沙子。他有时花上几天的时间来创作一件作品，结果却看着它被大海或风暴冲走，而这正是他喜欢的方式。

Ⅳ.七选五
KidsandFood：AdviceforParents
It is important for parents to know how to help their kids eat healthily.Here are a few easy ways：

Parentscontrolthesupplylines.
1 Though kids may keep asking for less nutritious(有营养的) foods，parents should decide which foods are regularly provided in the house.Kids won’t go hungry.They’ll eat what’s available in the fridge at home.
Saygoodbyetothe“cleanplateclub”．
2 Lots of parents grew up under the cleanplate rule，but that way doesn’t help kids listen to their own bodies when they are full.When kids feel full，they’re less likely to overeat.
3
Food preferences are developed early in life，so try to offer different kinds of foods.Likes and dislikes begin forming even when kids are babies.Parents may need to serve a new food on several different occasions for a child to accept it.
Foodisnotlove.
Find better ways to say “I love you”．When foods are used to reward kids and show love，they may start to turn to food when feeling worried or unhappy.4
Kidsdoasyoudo.
5 When trying to teach good eating habits，try to set the best example.Choose nutritious foods，eat at the table，and don’t forget breakfasts.
A．Start them young.
B．Rewrite the kids’ menu.
C．Be a role model and eat healthily yourself.
D．Offer praise and attention instead of food treats.
E．Let kids stop eating when they feel they’ve had enough.
F．You decide which foods to buy and when to serve them.
G．Let kids choose what to eat and how much of it they want.
1．答案　F
解析　由该段标题“Parents control the supply lines.”和文中的“parents should decide...in the house”可知F项内容符合此处语境。
2．答案　E
解析　由该段标题“Say goodbye to the ‘cleanplate club’”和文中的“that way doesn’t help...when they are full”可知，如果孩子感觉吃饱了就不要再强迫他们非得把盘子里的食物吃光，这样对身体不好，故选E项。
3．答案　A
解析　本段主要是说要帮助孩子从小养成不挑食的好习惯，故用A项作为小标题最恰当。
4．答案　D
解析　由该段标题“Food is not love.”和文中的“When foods are used...feeling worried or unhappy.”可知，作者建议不要用食物作为奖励，而是应该给予表扬和关注，故选D项。
5．答案　C
解析　由该段标题“Kids do as you do.”和文中的“When trying to teach good eating habits，try to set the best example.”可知，要想培养孩子良好的饮食习惯，父母首先得以身作则，故选C项。
