　　Scientists have found that poor health has a close association with sugar rather than
fatty food. This is true regardless of how healthy the rest of your diet might be. High-
calorie food，which is usually junk food with a large amount of sugar， like desserts，
should be cut out of your diet if you want to keep healthy. Beyond this， you’re supposed
to consume different categories of foods， like fruit and vegetables， meat， beans，
rice， and dairy products， since they consist of a quantity of fundamental nutrients.
After all， the ideal diet is a balanced one. Finally， to have a healthy eating habit，
you’d better chew slowly and eat a modest amount of food each time. Overall， there is
no trick to healthy eating. You need to be careful with your recipe and your health will
somewhat get improved.

(1)本句中两个that均引导同位语从句，解释说明the interesting fact的具体内容。空前
的this指的是第一个that引导的从句所说的内容。
(2)注意本句中的outperforming。outperform为复合动词，表示＂胜过，超过＂。2021

1. [人教选必②-3]For example， America’s most popular Chinese dish is General Tso’s
chicken， which (consist) of fried chicken covered in a sweet sauce， flavoured with hot red peppers.
教师尊享 点拨
　　本题中，所填词在which引导的非限制性定语从句中作谓语，其数应与先行词
General Tso’s chicken(一道菜名)保持一致，故填单数consists。
consists　
2. The beauty of air travel consists its speed and ease.
3. 养育孩子不仅有欢乐，还有焦虑和沮丧。
Raising a child not only happiness， but also anxiety and depression.

(1)本题除了可以填consists of外，还可以填is made up of，is composed of，is comprised of。
(2)使用表示＂由……组成(或构成)＂的几个短语时应注意：consist of没有进行时态
和被动语态，这是它与其他几个短语的主要区别。consisting of作状语或后置定语
时，可替换为made up of/composed of/comprised of。

　　despite和in spite of后不可以直接跟从句。若接从句，常在其后加the fact that，
即despite/in spite of the fact that。
★regardless of 后既可跟名词、动名词，也可跟whether，what，how引导的从句。
★regardless of＝despite＝in spite of
6 形容词(短语)作状语
1. (surprise)， Tony stood up and accepted the prize.
教师尊享 点拨
　　通过本题比较形容词作状语与副词作状语的区别：
☆Surprised，Tony stood up and accepted the prize.(Surprised描述Tony的状态，即Tony
自己感到惊讶)
☆Surprisingly， Tony stood up and accepted the prize.(Surprisingly修饰整个句子，
即＂Tony站起来去领奖＂这件事让人很意外)
Surprised　
2. 我聚精会神地读书，都没注意到已经半夜了。
， I didn’t notice that it was already midnight. (absorbed)
3. 既兴奋又感动，他们泪流满面。(读后续写之情绪描写)

词有lost，occupied，absorbed，involved等。

　　[2024天星原创]Roughly one-third of the food produced in the world for human
consumption every year — approximately 1.3 billion tonnes — gets lost or wasted. And in
Singapore 665，000 tonnes of food waste was produced in 2020， amounting to $342
million， only 19％ of which was recycled. Chua Kai-Ning and her partner， Phua Jun
Wei， founded Insectta in 2017. They are battling Singapore’s food waste with the help of
the black soldier fly larva — the immature form of a fly.
一
二
三
　　＂The idea behind Insectta is that nothing goes to waste，＂ said Chua. ＂Waste can
be reimagined as a resource if we change how we think about our production methods，
and how we deal with waste.＂
　　The worms of black soldier flies consume up to eight tons of food waste per month.
Insectta can then flash dry the worms into animal feed， and use the insects’ excrement(粪
便)for agriculture. According to Chua， Insectta is extracting more than agriculture-
related products from black soldier flies.
　＂During the research and development， we realized that a lot of precious
biomaterials that have already got market value can be gained from these flies，＂ Chua
said. Insectta has developed technology to get biomaterials from the exoskeleton(外骨骼)
they leave behind.
一
二
三
　　One of these biomaterials is chitosan， an antimicrobial(抗菌的) material sometimes
used in makeup and medicine. Insectta aims to eventually produce 500 kilograms of chitosan a day. Insectta is now working with Singapore-based Spa Esprit Group for the use of the chitosan in its skin care products. It also joins hands with the face mask brand Vi-Mask， which hopes to use the chitosan to make an antimicrobial layer within its products.
　　世界上每年都有大量的食物被浪费，新加坡的一家名为Insectta的公司利用黑水
虻解决食品废弃物，把黑水虻的粪便应用于农业，并从黑水虻的外骨骼中提取出了
可用于化妆品和药品等的材料。

（　B　）1. What do the figures in paragraph 1 show？
A. The difficulty in recycling food waste.
B. The seriousness of food waste.
C. The urgency of reducing food consumption.
D. The effort at battling food waste.
[解析]　推理判断题。由第一段内容可知，全世界每年有大约13亿公吨的食物被浪
费，2020年新加坡产生了665 000公吨食品废弃物，其中只有19％得到了回收。由此
可知，作者通过列数字的方式来表明食物浪费的严重性，故选B项。
B
一
二
三
（　B　）2.What does the underlined word ＂extracting＂ in paragraph 3 mean？
A. Protecting. B. Obtaining.
C. Learning. D. Recycling.
[解析]　词义猜测题。由第三段中的＂use the insects’ excrement(粪便) for agriculture＂可知，该公司把黑水虻的粪便应用于农业，再结合下文可知，该公司还从黑水虻的外骨骼中获取了抗菌生物材料。由此可推知，该公司从黑水虻身上获取的不只是与农业相关的产品，故画线词的含义应是＂获取＂，B项切题。
B
一
二
三
（　A　）3.What can be inferred about chitosan？
A. It has a wide range of uses.
B. It brings few profits to Insectta.
C. It has been applied to masks.
D. It is found in the fly’s excrement.
[解析]　推理判断题。由最后一段中的＂used in makeup and medicine＂＂for the use of the chitosan in its skin care products... to make an antimicrobial layer within its products＂可知，这种抗菌材料可用于化妆品和药物中，也可用于护肤产品中，还可用于口罩的抗菌层。由此可知，这种抗菌材料用途广泛，故选A。
A

（　C　）4.Which is the best title for the text？
A. Insects provide a way to recycle food waste
B. New technology is developed to fight food waste
C. Insectta is using insects to turn waste into treasure
D. Singapore is benefiting from the insect-based industry

　　[科技创新/2024天星原创]Diners in Japan may soon be able to cut their salt intake
without needing to sacrifice(牺牲) flavor. Researchers recently announced they developed
electric chopsticks that increase saltiness of foods.
　　Co-developed by Meiji University professor Homei Miyashita and drink producer
Kirin Holdings Company， Limited， the chopsticks improve tastes using electrical
stimulation and a mini-computer attached to a wrist. ＂The device uses a weak electrical
current to send sodium ions(钠离子) from food， through the chopsticks， to the mouth
where they create a sense of saltiness，＂ said Miyashita. ＂As a result， the salty taste
increases by 1.5 times.＂

　　The taste-improving chopsticks may have particular relevance to the traditional diet
in Japan， which tends to be high in salt. The average Japanese adult eats about 10 grams
of salt each day. That is almost two times the amount suggested by the World Health
Organization. High sodium intake is linked to increased cases of high blood pressure，
strokes and other conditions. ＂To prevent these diseases， we need to reduce the amount
of salt we take，＂ said Kirin researcher Ai Sato. Sato added that if Japanese people try to
reduce salt intake in the usual ways， they will need to cut many of their favorite foods
from their diet. Otherwise， they would have to eat flavorless food.

　　＂I want to overturn the idea that low salt means no flavor，＂ Miyashita declared. ＂ The chopsticks make it possible to keep enjoying the foods we love， and in a healthier way.＂ He was confident that the chopsticks can help people make better decisions about their diet and hoped to have them ready to sell as early as next year.
　　Miyashita and his research team have explored different ways that technology can interact with human senses. He has also developed a television screen that a person can
lick(舔) to taste different food flavors. Meanwhile， research is also underway to develop
other eating tools with special functions like electric spoons and forks using technology.

（　D　）1.Who would probably be interested in the electric chopsticks？
A. Those sticking to a balanced diet.
B. Those having eating disorders.
C. Those preferring homemade food.
D. Those wanting to take in less salt.
[解析]　细节理解题。由文章第一段中的＂Diners in Japan may soon be able to cut their salt intake＂可知，这种电动筷子对想要减少盐摄入量的人有吸引力，故D项正确。

（　D　）2.Why is traditional Japanese diet mentioned？

[解析]　推理判断题。由题干中的＂traditional Japanese diet＂可将解题信息定位至第
三段。由本段对日本传统饮食的介绍可知，日本的传统饮食盐味较重。普通的日本
成年人每天摄入的盐量几乎是世界卫生组织建议的两倍。高钠摄入量与高血压、中
风和其他疾病病例的增加有关。如果日本人以平常的方式减少盐的摄入，他们将需
要舍弃许多他们喜欢的食物。否则，他们将不得不吃寡淡无味的食物。再结合上文
中提到的电动筷子可以增加食物的咸味可推知，文中提及日本传统饮食是为了解释
研究人员发明电动筷子的原因。综上可知，本题选D。

（　A　）3.What does Miyashita expect of the electric chopsticks？
A. They’ll reach consumers in the near future.
B. They’ll help change people’s eating habits.
C. They’ll be developed into various versions.
D. They’ll inspire a whole new line of research.

school for supper. Nervous and unsure of the food and table manners， we politely agreed.
　1　 And now my first dining experience would be with the school staff.
Compared with the restaurants in my hometown， Chinese ones are loud and busy.

means drinking and drinking. You’ll never have an empty glass.

Chinese really eat everything！
Every day I’m pushed out of my comfort zone. 　5　 The experience itself is quite
amazing. I’ve learned a lot， yet there’s still so much to learn. It sure is different from my
