10．Almost everyone suffers from a headache （61）occasionally（occasional）．But some people suffer from repeated，frequent headaches．
What is headache？What causes it？What can you done about a headache？What research is being done on headaches？The dictionary defines headache simply （62）as"a pain in the head"．（63）Whatmost people mean by headache （64）is（be） a pain that lasts several minutes or hours．It covers the whole head，or one side of it，or perhaps the front or the back of the head．To add to the confusion about a definition，some people call tight feeling in the head a headache．
A headache is important because （65）itcan be the first warning of a serious condition which probably could be controlled （66）if/whendiscovered early．If a person （67）removes（remove） the warning，day after day，with a pain-killer，he may pass the point of easy control．
A headache is important also because it disturbs people，（68）preventing（prevent） them from living a happy life．The （69）employer/employee（employ） with a headache does less work．In a flash of temper he may upset his fellow （70）guys（guy） or customers，causing a direct or indirect loss to his organization．The mother with a headache suffers and disturbs the family．She upsets her husband and children．

分析 本文是一篇說明文，介紹什么是頭痛，頭痛的原因以及頭痛帶來的影響．

解答 61．occasionally    62．a(chǎn)s    63．What    64．is． 65．it    66．if/when    67．removes     68．preventing    69．employer/employee    70．guys
詳解：
61．答案occasionally．考查副詞．此處應(yīng)用occasion的副詞性來修飾本句的謂語動詞suffers from． 
62．答案as．考查固定搭配．此處考查define．a(chǎn)s的固定搭配，"把…定義為…"． 
63．答案What．考查主語從句． most people mean by headache 為主語從句，（be）為謂語，a pain作賓語，此處要填的是主語從句的引導(dǎo)詞，并在主語從句中作主語，故填What． 
64．答案is．考查時態(tài)．此處的be動詞用作謂語功能，根據(jù)主謂一致的原理，當(dāng)主語從句作主語時，謂語動詞一般用單數(shù)，故填is． 
65．答案it．考查代詞．此處應(yīng)用it代替前文的a headache． 
66．答案if/when．考查狀語從句．此處考查的是省略式狀語從句的引導(dǎo)詞，此部分相當(dāng)于if/when it is discovered early． 
67．答案removes．考查時態(tài)．此處的句子結(jié)構(gòu)要求本空應(yīng)該填入謂語形式，全文時態(tài)為一般現(xiàn)在時，應(yīng)用一般現(xiàn)在時作謂語，且用主動概念，故填removes． 
68．答案preventing．考查非謂語．此處考查prevent用作非謂語功能，與前文的a headache形式邏輯上的主謂關(guān)系，所以應(yīng)該用現(xiàn)在分詞形式． 
69．答案employer/employee．考查名詞．此處缺少一個名詞作主語，表示"雇主或雇員"的意思． 填employer/employee．
70．答案guys．考查的是名詞變復(fù)數(shù)．根據(jù)"or customers"可知，此處應(yīng)用名詞復(fù)數(shù)，guy的復(fù)數(shù)形式應(yīng)是guys，不可變y為i，再加es．

點(diǎn)評 語法填空題，在了解全文大意的基礎(chǔ)上，從語篇著手并聯(lián)系上下文，根據(jù)自己掌握的語法知識、詞匯知識、生活常識、固定詞組、句型搭配及對某一國家的風(fēng)俗習(xí)慣、文化背景的了解、行文的邏輯關(guān)系、語篇標(biāo)志等進(jìn)行填空．同時，記住常用的動詞短語、介詞短語和重要的句子結(jié)構(gòu)等是必要的．

15．If you are a fruit grower-or would like to become one-join in Apple Day to see what's around．It's called Apple Day but in fact it's more like Apple Month．The day itself is on October 21，but since it has become popular，events now last through most of October around Britain．
Visiting an apple event is a good chance to see，and often taste，a wide variety（品種） of apples．To people who are used to the limited kinds of apples such as Golden Delicious and Royal Gala in supermarkets，it can be quite eye-opening to see some classical apples still in existence，such as Decio which was grown by the Romans．Although it doesn't taste of anything special，it's still worth a try．
There are also varieties developed to suit certain local conditions．One of the very best varieties for eating quality is Orleans Reinette，but you'll need a warm，sheltered place with perfect soil to grow it，so it's  a pipe dreamfor most apple lovers who fall in love with it．
At the apple events，you can also meet expert growers and discuss which ones will best suit your conditions，and because these are family affairs，children are well entertained with apple-themed fun and games．
Apple days are being held at all sorts of places with an interest in fruit，including stately gardens and commercial orchards（果園）．If you want to have a real orchard experience，visit the National Collection at Brogdale，near Faversham in Kent．

2．Would you ever hug a stranger？There's actually a social activity of offering hugs to strangers in public places．It's known as the Free Hugs Campaign．The hugs are meant to be random（隨機(jī)的） acts of kindness-selfless acts performed just to make others feel better．The person offering the hugs often makes a sign that reads"FREE HUGS"，then holds it up in the street and waits for someone to ask for a hug．

The activity was started by Australian Juan Mann in 2004．Juan had been living in London for almost 10 years when he decided to return to Sydney after his girlfriend decided to leave him．On landing，he had nothing but his suitc ase．After about three months，an old friend invited him to a party．In an interview with WHO magazine，Juan said that while he was at the party，"…a completely random person I didn't know came up to me and gave me a hug．I felt like a king!It was the greatest thing that ever happened．"Then，he had an idea．
On 30th June 2004，Juan made a sign with the words FREE HUGS and offered his first hugs in the center of the main shopping district in Sydney．"For the first 15 minutes，people just stared right through me．But then a woman tapped me on the shoulder and told me she needed a hug as one of her relatives had passed away，"said Juan．
Things really took off after a FREE HUGS video was uploaded to YouTube．While in Sydney，Juan met an American musician，Shimon Moore，who filmed Juan giving away free hugs and later used what he had shot to make a music video for the song All the Same by his band The Sick Puppies．The video was later uploaded to YouTube，where it has been viewed over 70 million times．
As a result of the video，the Free Hugs activity became international and then developed to China，Italy，America，Switzerland，Norway，India，Portugal and the UK．An International Free Hugs Day was set on the first Saturday following 30th June as this was the date of the first time that Juan ever offered free hugs in Sydney．
52．What is the purpose of the Free Hugs Campaign？To show kindness to others and make them feel better
53．What gave Juan Mann the idea of offering free hugs？A stranger's hug which cheered him up
54．How did Shimon Moore help Juan's activity become well-known？By filming Juan's activity to make a music video and uploading it to YouTube．

11．Selfies （自拍） have become an increasingly common way to capture memorable moments．When it comes to taking selfies，knowing the following tips can directly affect the quality of your final product．
The use of light is vital to improving image quality．Lights can help avoid shadows and create soft features on your face，so turn your face toward the main light source．If you want to be creative，play with light angles by turning your body，but make sure the photo is properly exposed and your face is lit from the front or the side．Besides，avoid taking selfies against the main light source or with overhead lighting．In addition，natural light possesses a warmth that makes you look like you're glowing．（發(fā)光）
When taking selfies，angles also matter a lot．Hold the camera away from your face，and try to take photos both horizontally（水平地） and vertically（垂直地）．If not，your face might look bigger than usual．Ideally，the universal selfie angle is 45degrees above your head．But you should study your face at different angles because finding your best angle requires you having seen all of them．
One problem with selfies is that most have distracting backgrounds．You can always do more to show others your best side．Try to simplify the background by taking selfies outdoors or in spacious areas．Document yourself engaging in interesting activities---hiking with family members，visiting landmarks，or working out with friends．At least，you can make the photo appealing by getting rid of your outstretched arm or a background that's too busy．
You can also download some photo apps that allow you to adjust the lighting and contrast．Some apps offer useful filters，which can change your skin tone and remove pimples （粉刺） on your face．

1．To get an image of high quality，you need toC．
A．be under the light source
B．be against the main light
C．face the main light source
D．have the photo fully exposed
2．How can you find the angle that suits you most？A
A．Study your face at different angles．
B．Hold the camera far enough from you．
C．Keep the camera lower than your face．
D．Place the camera 45degrees above your head．
3．Which of the following should be avoided when taking selfies？D
A．The use of natural light．
B．A landmark as a background．
C．Changes of the skin tone．
D．A busy background．
