pain的用法
①表示身體某部位的疼時(shí)，為可數(shù)名詞。如：
She has a pain in her back/ leg/ head. 她背（腿、頭）疼。
②表示由損傷或疾疾引起的痛苦、疼痛時(shí)，為不可數(shù)名詞。如：

午飯我吃了面條、沙拉，然后又吃了一個(gè)桃子。我因?yàn)楦械讲皇娣酝盹垱](méi)吃東西。
①for lunch中的for是介詞，構(gòu)成固定結(jié)構(gòu)have…for…如：
What did you have for breakfast?
He had nothing for supper.
②feel very well中的well不是副詞，而是形容詞，意為“健康的”。如：
She is well in health. 她身體很健康。
6．Was the peach ripe or green? You ought to be careful with fruit.
桃子熟不熟？吃水果你該小心。
①句子中的green作“沒(méi)有成熟的”解，是ripe（成熟的）反義詞。例如：
The cherries are still too green to pick. 這些櫻桃還太生，不能摘。
另外，green還可以表示“對(duì)環(huán)境無(wú)害的”，如閱讀材料中第3段第6行的句子：…（who）have tried to use green and clean ways to make the foods（盡量使用綠色干凈的方式制作食品）。
green也可意為“無(wú)經(jīng)驗(yàn)的，沒(méi)有受過(guò)訓(xùn)練的”。如：
He is still green at this job. 他對(duì)這件工作還很生疏。
②be careful with fruit = be careful in eating fruit意為“吃水果時(shí)小心”。
7．It was a bit green. 它有點(diǎn)生。
①a bit和a little在肯定句中修飾動(dòng)詞、形容詞、副詞及其比較級(jí)，可以換用。表示“一點(diǎn)兒”。如：
The speaker spoke up a bit/ a little so as to make himself heard more clearly. 演講者把嗓音提高一點(diǎn)，以便使別人聽(tīng)得清楚。
②a bit和a little在否定句中，意思正好相反。
not a bit=not at all
not a little=very much
試比較：I’m not a bit tired. 我一點(diǎn)也不累。
I’m not a little tired. 我非常累。
③a little可直接作名詞的定語(yǔ)，而a bit則要在后面加of構(gòu)成短語(yǔ)才能作定語(yǔ)，二者都只能修飾不可數(shù)名詞。如：
There’s only a little/ a bit of food left for lunch. 午餐只剩一點(diǎn)兒食品了。
注意：a bit of的復(fù)數(shù)是bits of，而a little不能變復(fù)數(shù)。
8．And I advise you not to eat fruit that isn’t ripe in the future.
我建議你將來(lái)不要吃不熟的水果。
1）advise意為“建議，忠告，勸告”，常用于下面五種結(jié)構(gòu)：
①advise+n./ pron.
②advise sb.（not）to do sth.
③advise doing sth.
④advise sb. against（doing）sth.
⑤advise sb. +that sb.（should）do sth. （從句中用should do的虛擬語(yǔ)氣）
The doctor advises a change of air. 醫(yī)生建議換換空氣。
The doctor advised me to take more exercise. 醫(yī)生建議我多做運(yùn)動(dòng)。
We advised waiting till the proper time. 我們建議等待適當(dāng)?shù)臅r(shí)機(jī)。

I advised him that he (should) attend the meeting. 我勸他參加這次會(huì)議。
advice是advise的名詞形式，它是一個(gè)不可數(shù)名詞。常用于：give（some）
advice on sth./ how to do…；ask for advice; follow/ take sb’s advice等。
2）in the future作“將來(lái)”（in time yet to come）解。
試比較in future作“今后”（from now on）解。例如：
You’d better not go out alone in future. 今后你最好不要單獨(dú)外出。
No one knows what will happen in the future. 沒(méi)人知道將來(lái)會(huì)發(fā)生什么事情。
9．Choosing what to eat is no longer as easy as it once was.
選擇吃什么東西不再像以前那么容易了。
What to do是疑問(wèn)詞+不定式的結(jié)構(gòu)，在句中作賓語(yǔ)，另外這一結(jié)構(gòu)也可作主語(yǔ)、表語(yǔ)、定語(yǔ)等。如：
①what to do next hasn’t been decided yet.（主語(yǔ)）
②I don’t know whether to answer it.（賓語(yǔ)）
③The question is how to put it into practice.（表語(yǔ)）

④They exchanged views on the question of whom to elect.
關(guān)于應(yīng)當(dāng)選誰(shuí)的問(wèn)題，他們交換了意見(jiàn)。（介詞短語(yǔ)）
⑤The key with which to open the door has been lost.
開(kāi)這扇門的鑰匙不見(jiàn)了。（定語(yǔ)）
注意：這種結(jié)構(gòu)含有情態(tài)意義，它相當(dāng)于一個(gè)帶should的從句。如第②題I don’t know whether I should answer it.
10．Our eating habits have changed, as has our way of life, and the fuel we need for our bodies is also different.
像我們的生活方式一樣，我們的飲食習(xí)慣已發(fā)生了變化，我們身體所需要的燃料也不同了。
as在句中引起方式狀語(yǔ)從句，此處采用了省略形式，并且是倒裝結(jié)構(gòu)，若改用正常語(yǔ)序則為as our way of life has changed。
as引起的方式狀語(yǔ)從句中一般采用正常語(yǔ)序，但在正式語(yǔ)體中，也可采用倒裝語(yǔ)序。如：

對(duì)于21世紀(jì)的人來(lái)說(shuō)，傳統(tǒng)飲食常常含有太多的脂肪和太多的卡路里。
①diet與food的區(qū)別：diet和food都可作“食物”解。但diet指的是習(xí)慣的食物或規(guī)定的食物，特指維持健康的定量或定質(zhì)的食物，如病人的療養(yǎng)飲食。food是一般的詞語(yǔ)，凡能吃喝的東西都可稱為food。如：
The doctor has ordered me a special diet. 醫(yī)生給我安排了特殊的飲食。
Proper diet and exercise are both important for health.
Milk is the natural food for young babies.
②too much與too many的區(qū)別
too much可以作形容詞，修飾不可數(shù)名詞，也可用作副詞，修飾動(dòng)詞。例如：
There is too much rain here in spring. 春天這里的雨水太多。
She talked too much at the meeting. 她在會(huì)上講得太多了。
too many可作形容詞，修飾可數(shù)名詞。
③calorie=calory卡路里或卡，指食物所產(chǎn)生的熱量，也可以作熱量單位。例如：

12．If you want to keep up with the high pace of modern life, we had better learn to make the right choices about what and how we eat.
要是我們想跟上現(xiàn)代生活的快節(jié)奏，我們最好在吃的東西和吃的方式上學(xué)會(huì)做出合適的選擇。
keep up with意為“跟上，不落后于”，表示并肩前進(jìn)，并駕齊驅(qū)。如：

他因?yàn)樯W(xué)習(xí)落后了，但現(xiàn)在正在奮起直追。
13．Calcium, which is found in eggs, milk and other dairy products, is good for our bones and teeth.
雞蛋、牛奶及其他乳制品所含的鈣對(duì)我們的骨骼和牙齒有好處。
①be good for意為“對(duì)……有好處”（反義短語(yǔ)為be bad for）如：
Walking is good for our health.
Milk is good for children. 牛奶對(duì)孩子有好處。
②product指任何體力勞動(dòng)或腦力勞動(dòng)所生產(chǎn)的東西，含義最廣，是可數(shù)名詞。
production指生產(chǎn)的動(dòng)作或產(chǎn)量，也指生產(chǎn)的結(jié)果，還特指藝術(shù)作品。
produce作名詞時(shí)，指農(nóng)產(chǎn)品、天然產(chǎn)物或工業(yè)產(chǎn)品的總稱，是不可數(shù)名詞。
They must have new markets for their products. 他們的產(chǎn)品必須得有新市場(chǎng)。
The plan was the product of many hours of careful thought.
這個(gè)計(jì)劃是經(jīng)過(guò)數(shù)小時(shí)深思熟慮的產(chǎn)物。

14．Many people today make choices about their eating habits based on what they believe.
今天，許多人基于他們自己的看法對(duì)飲食習(xí)慣做出選擇。
based on what they believe是過(guò)去分詞短語(yǔ)作狀語(yǔ)，修飾主句謂語(yǔ)。如：
We’ll spend the night locked in your room.
我們要反鎖在你的房間里度過(guò)這一夜。
15．Eating habits become part of who we are.
飲食習(xí)慣成為我們的一部分特征。
part of who we are表明飲食習(xí)慣在一定程度上反映出我們是什么樣的人，也就是說(shuō)，通過(guò)飲食習(xí)慣可以看出一個(gè)人的一些特點(diǎn)。
16．We also make choices based on how the products are grown or made: environmentally friendly foods, or “eco-foods”, are made by companies who have tried to use green and clean ways to make the foods.
我們也根據(jù)產(chǎn)品的種植與加工手段做出選擇：綠色食品或“生態(tài)食品”是由那些盡量使用綠色或干凈的辦法生產(chǎn)出的。
①based on how the products are grown or made是過(guò)去分詞短語(yǔ)作方式狀語(yǔ)，how引起賓語(yǔ)從句，作介詞on的賓語(yǔ)。who have tried to use green and clean ways to make the foods是定語(yǔ)從句修飾companies，此處who表示公司里的人，若用which則表示公司這一地方。
②foods表示各種各樣的食品，所以用了復(fù)數(shù)，若單純表示數(shù)量，則food是不可數(shù)名詞。
17．Because we have so much to choose from, many companies and stores offer advice about what we should eat.
因?yàn)槲覀冇羞@么多東西可以選擇，許多公司和商店都對(duì)我們?cè)摮允裁刺岢鼋ㄗh。
to choose from是后置定語(yǔ)，修飾so much，構(gòu)成動(dòng)賓關(guān)系。
choose與choose from的辨析
choose意為“選中”，“選出”
choose from意為“從……中挑選”，from后接選擇的范圍
Have you chosen a hat yet? 你選了帽子了嗎？
There’re different kinds of toys to choose from.
18．The same goes for “crash diets” that some companies say will make us lose weight fast.
有些公司建議我們用來(lái)快速減肥的“速成食療”也是如此。
①go在本句中意為“行得通，起作用”。再如：
This truth goes everywhere. 這個(gè)真理到處適用。
go也可意為“流傳；表達(dá)”。如：
As the saying goes, a bird in the hand is worth two in the bush.
俗話說(shuō)，雙鳥在林不如一鳥在手。
②some companies say是定語(yǔ)從句中的插入語(yǔ)，這種插入語(yǔ)應(yīng)位于關(guān)系代詞之后。如：
Choose the one answer which you think is correct in the following.
在下列句子里選擇一個(gè)你認(rèn)為正確的答案。
19．We ought to learn more about our body and the fuel it needs to keep fit. Only in that way will we be ready for the challenges and opportunities in life.
對(duì)于我們的身體以及身體所需要的燃料我們應(yīng)多加了解。只有這樣我們才能做好充分準(zhǔn)備，以應(yīng)對(duì)生活中的挑戰(zhàn)與機(jī)遇。
①it needs是定語(yǔ)從句，修飾fuel；so that引起目的狀語(yǔ)從句。
②be well prepared for=be ready for意為“為……做好充分準(zhǔn)備”，表示一種狀態(tài)，be若換成get則表示動(dòng)作，不延續(xù)。如：
We are well prepared for the exam now. 現(xiàn)在我們已為考試做好了充分準(zhǔn)備。
Have you got prepared for the sports meet?
比較：be preparing for意為“在為……做準(zhǔn)備”。如：

When I’m preparing for my performance, I don’t like to be interrupted.
我正為表演做準(zhǔn)備時(shí)，不喜歡被別人打擾。
③only后面跟介詞短語(yǔ)，作狀語(yǔ)時(shí)，引起部分倒裝。
20．If our body is short of any of its kind, we will become sick.
如果我們的身體缺乏任何這一類物質(zhì)，我們就會(huì)生病。
be short of作“缺乏，不足”解。例如：
They are short of nothing but time. 他們不缺任何東西只缺時(shí)間。
21．Even if we choose nutritious food for our main meals, we probably still need to refuel now and then.
即使我們選擇營(yíng)養(yǎng)食品作為我們的主餐，我們有時(shí)可能仍需要補(bǔ)充燃料。

Even if they offered to pay, I wouldn’t accept any money from them.
即使他們主動(dòng)提出付款，我也不會(huì)收他們的錢的。

I like to go to the opera now and then. 我有時(shí)喜歡去看歌劇。
22．We can give our body and brain more energy by eating snacks.
通過(guò)小吃我們可以給我們的身體和大腦提供更多的能量。
①brain表示“大腦、頭腦”時(shí)，既可以是可數(shù)名詞，也可以是不可數(shù)名詞，如：
He’s nice, but hasn’t got much brain. 他人不錯(cuò)，但沒(méi)大有頭腦。
The man has a fine brain. 這人腦子很好用。
brain表示“頭腦、智慧”時(shí)常用brains，此時(shí)為不可數(shù)名詞。如：
Brains is more than just education. 有頭腦不僅指受過(guò)教育。
He has much brains. 他很有頭腦。
23．Best of all, they taste great!
最棒的是，它們味道好極了！
best of all意為“最好的是，最突出的是”。如：
Best of all, the medicine can help you sleep.
最佳的是，這藥對(duì)你的睡眠有幫助作用。
24．Most fruits are naturally sweet and we can eat them just the way they are-all we have to do is clean or peel them.
多數(shù)水果本身就是甜的，我們可以不用加工就吃--所有要做的是就是洗凈、去皮。
①the way they are中的they are是定語(yǔ)從句，the way后接定語(yǔ)從句時(shí)，一般用in which引導(dǎo)，也可以省略，也可換成that。如：
These are some of the ways in which they can be used.
He doesn’t speak the way (that) I do. 他說(shuō)話方式不像我。
②all we have to do is clean and peel them中clean and peel是省去to的動(dòng)詞不定式，當(dāng)主語(yǔ)部分含有實(shí)義動(dòng)詞do時(shí)，作表語(yǔ)的不定式可以省略to。如：
The only thing I can do is lie in bed. 我唯一能做的就是躺在床上。
What you should have done was press the button.
你本該做到的就是按下這個(gè)按鈕。
