A．

what； which

B．

C．

D．

分析上個月我回到家鄉(xiāng)幾乎迷路了，因為它不再是30年前的樣子，那個時候它僅僅是一個小村莊．

解答答案為C．本題考查名詞性從句中引導詞的運用．題干中第一空格后面是連系動詞is后面的表語從句，從句中缺少表語，that在名詞性從句中不擔任成分，排除B；which在名詞性從句中表示選擇，該句中無選擇的含義，排除D；what可以在名詞性從句中做主語、賓語和表語；第二空是非限制性定語從句，先行詞在從句中做時間狀語，故選C．

點評名詞性從句考查的關(guān)鍵是連接詞的選用和語序，因此，我們首先要搞清從句的性質(zhì)，掌握各連接詞的用法，在此基礎(chǔ)上判斷．此外，關(guān)注名詞性從句用陳述語序．

14．Why are people interested in eating raw foods or whole foods One reason is that eating these types of food reduces the risk of acid accumulation in your body．
    Raw and whole foods are usually digested more efficiently than cooked and refined foods．When we cook foods，we destroy the natural enzymes（酶）that are part of the food in its raw form．These enzymes were intended by nature to help us digest the food．When we consume food without these natural enzymes，our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream．In both instances，the result is obesity．When too many nutrients are absorbed at once，the body grows fat．Improperly digested food moves slowly through the digestive tract，where it becomes increasingly acidic （酸性的）．To protect its vital organs from this acidic waste，the body changes the acid into fat and stores it safely away from the organs．
    Processed foods contain chemical elements，which might confuse the appetite mechanism that tells us when we've had enough to eat； as a result，people often overeat．Processed foods also upset the digestive cycle．The body will either identify these foods as allergens and then store them safely away from the organs as fat，or the remains of undigested food will become acidic and enter the bloodstream as acid waste，which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body's cells．The body's metabolism（新陳代謝） becomes inactive，and then result is weight gain and obesity．
    The accumulation of acid in the digestive tract makes digestion increasingly inefficient．When that happens，even healthy foods can become acidic and the food allergies will become more common．
    To stop this vicious（惡性的） circle in its tracks，people need to consume food and supplements that will neutralize （使…中和）the acid already accumulated in body．Eating the right types of raw and whole foods can help．It's also important to restore your enzyme balance．You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production．If you truly want to change and help your body heal itself，you need to take an active approach．．
30．What is the main purpose of this passageC
A．To inform people of the harm of processed foods
B．To tell the differences between raw and processed foods
C．To advocate eating more raw and whole foods
D．To warn people of the problem of obesity
31．It can be inferred from Para.2 thatA
A．foods with natural enzymes help people keep fit
B．it is essential for people to protect their vital organs
C．we'd better be cautious about raw and whole foods
D．giving up cooked and refined foods is a new lifestyle
32．Processed foods are unhealthy because theyB
A．destroy body's cells
B．may lead to obesity
C．a(chǎn)re difficult to digest
D．stop body's metabolism．

Childhood is a time when there are little duties．If a child has good parents，he is fed，looked after，and loved no matter when he may do．It's impossible for him to be given such much again in his later life．But a child is not so free to do as he wishes it．He is continually being told not to do this，not to do that，or being punished for what he had done wrong．
When the young man starts to make their own living，he becomes free from the rules of school and parents．Therefore，he can no longer expect others to pay his food，his clothes，and his room．He has to work hard to live comfortable．If so，he can have the great happiness of build up his own position in society．
