形容词
一、形容词的用法
形容词修饰名词或代词，说明事物或人的性质或特征。通常，可将形容词分成性质形容词和类别形容词两类，其位置不一定都放在名词前面。
1．性质形容词
直接说明事物的性质或特征的形容词。它有级的变化，可以用程度副词修饰，在句中可作定语、表语和补语。如：hot(热的)，happy(快乐的)，beautiful(美丽的)。这类形容词占大多数。
The beautiful girl spoke excellent English．
这个漂亮的女孩说一口极好的英语。
The girl is beautiful．
这个女孩很漂亮。
2．类别形容词
因为这类形容词只能作表语，所以又称为表语形容词。这类形容词没有级的变化，也不可用程度副词修饰。大多数以a开头的形容词都属于这一类，如：afraid(害怕的)，alone(单独的)，asleep(睡着的)，alive(活着的)，awake(醒着的)，以及worth(值得的)，unable(不可能的)等。
We don't know whether he is alive．
我们不知道他是否还活着。
The boy is afraid of his father．
这个男孩怕他爸爸。
[名师点津] 多数形容词作定语和表语时词义相同，少数在意思上有区别。如ill作表语时，意为“生病的”；作定语时，则表示“坏的”“不良的”“不吉利的”。

2．有时状语从句可以省略。

Here are some fantastic parks in San Antonio．
Brackenridge Park
The park was first established in 1899 and has been popular with both locals and visitors ever since．Towering trees and peaceful riverbanks will greet guests along the park's paths，and the facilities include playgrounds，museums，a miniature train，a Japanese tea garden，and one of the oldest golf courses in the city．
Friedrich Wilderness Park
In the park，you'll find about 10 miles of paved(铺过的)and unpaved trails(路线)，with a little something for everyone．From rocky climbs to deep canyons and enchanting forests to open views，there's no shortage of natural beauty．The area is nationally famous for birdwatching．
San Antonio Missions National Historical Park
The park is the state's only one on the list of UNESCO World Heritage Site．It covers quite a large area，so it's best to make it a full-day or at least a half-day trip so you can be sure to cover everything．While the Alamo is a separate attraction，you will get to enjoy the architectural wonders of Mission Concepcion，Mission San Jose，Mission San Juan，and Mission Espada．They're all connected by a hike and bike trail，with plenty of stops along the way to picnic，climb trees，and refill water．Admission is free!
Eisenhower Park
Just a 20- to 30-minute drive from the city center，the park puts the best landscapes in the Texas Hill Country on full display，holding 6 miles of hiking trails，both paved and unpaved．Explore dried creek beds，look out over plunging canyons，and enjoy full views of San Antonio down below．You can also find playgrounds for the little ones，picnic tables，and barbecue facilities．

Finding low-cost sustainable building materials is important for the environment and in providing access to affordable housing．Researchers have created a composite(复合的) building material by replacing sand in building materials with a common，non-degradable(不可降解的) waste product: used disposable diapers (一次性尿布)．
Driven by a desire to solve Indonesia's significant population growth and demand for low-cost housing，researchers looked for a way of maintaining the benefits of building materials but making it more environmentally friendly and cheaper to produce．Building material samples containing different proportions(比例) of disposable diaper waste were tested．Then the researchers calculated the maximum amount of sand that could be replaced with diaper waste，finding that up
to 8% of the sand could be replaced to safely construct a house with 36 square meters．10% of the sand could be replaced in a three-storey house and 27% in a single-storey house．In terms of the materials used to create partition walls (隔断墙)，the researchers said they could replace up to 40% of sand．
“This research has concluded that adding used diapers to building materials does not significantly weaken its strength，” the team stated．“It proves using diapers to create composite materials is feasible，particularly concerning the development of environmentally friendly and cost-effective materials．”
Indonesia is ranked sixth globally for disposable diaper usage．Many used diapers are thrown away in the country's rivers and waterways，causing pollution．In 2019，the total waste in Indonesia was 29.21 million tons．This figure rose to 32.76 million tons in 2020．
However，the researchers know the current limitations of using waste diapers as a construction material．For one thing，it would require engagement with waste treatment facilities to collect used diapers from households and deal with them．Secondly，machines that cut up the used diapers would be needed on a large scale．
Nonetheless，the research highlights the potential for using non-degradable waste，addressing sustainability issues and providing low-cost housing．
【语篇解读】 本文是一篇说明文。文章主要说明了出于环保考虑，研究人员发明了一种复合建筑材料——用一种常见的、不可降解的废物——用过的一次性纸尿裤——代替建筑材料中的部分沙子。文章解释了研究开展的经过以及这一方法的可行性。
4．Which is an advantage of replacing sand with used disposable diapers

B．Speeding up the construction of housing．
C．Increasing the weight of building materials．

5．What does the underlined word “feasible” in paragraph 3 refer to
A．Enormous． B．Conservative．
C．Practical． D．Urgent．
√
C [词义猜测题。根据画线词上文“This research has concluded that adding used diapers to building materials does not significantly weaken its strength”可知，研究结论指出在建筑材料中添加用过的尿布不会显著削弱其强度，说明用尿布制造复合材料是实用和可行的。由此可知，画线词意思是“实用的”。故选C。]

7．What can be the best title for the text
A．Building Materials Are in Great Demand
B．Indonesia's Awareness of Environmental Protection
C．A Further Study on Materials of Disposable Diapers

Ⅳ．阅读七选五
Several factors can influence your first impression of someone，including their physical features，voice and speech，surrounding environments，etc．It takes time to get to know personal characteristics that really convey (传达) someone's nature． 1 These tips can help．
Stay conscious(有意识的) of body language
Body language can convey quite a bit about how you feel in a given situation．A few tips to consider: open up your posture(姿势), make some eye contact and listen intently． 2 If eye contact feels uncomfortable，try just focusing on your posture．
Show your interest
Expressing interest in what someone has to say can help boost your chances of making a good impression．Try a thoughtful comment that keeps the conversation moving and makes it clear that you've been paying attention． 3 People generally want to know they can trust you．
Dress for the occasion
Previous research suggests that body language plays more of a part in first impressions than clothing．But your personal style can play a role，too．There's nothing wrong with expressing yourself through your clothing．Just know that certain situations do call for a slightly more formal look． 4 4
Make small talk
5 But it can often pay off when it comes to leaving a positive impression．Even simple comments，like “I really like this new professor” or “Those are great shoes”，can start a conversation they'll remember later．
While a first impression can set the tone(基调) for future interactions，it's also worth keeping in mind that first impressions are largely unconscious．Just approach every new meeting with kindness，compassion，and a willingness to grow．
A．What about learning a lesson from it at present
B．It's all too easy to accidentally say something inconsiderate．
C．And keep any comments or praise you offer honest and genuine．
D．Besides，the “right” dress doesn't always have to be fancy or new，either．
E．Are you in search of ways to leave the most favorable first impression possible
F．You don't need to do all of the above every time you're interacting with someone．
G．Small chat about the weather or other everyday topics can sometimes seem boring．
【语篇解读】 本文是一篇说明文。文章介绍了怎样给人留下良好的第一印象。
1．E [上文“Several factors can influence your first impression of someone，including their physical features，voice and speech，surrounding environments，etc．It takes time to get to know personal characteristics that really convey someone's nature．”说明第一印象的重要性，选项E承接上文，用问句的形式引出下文“These tips can help．”介绍文章主题：给人留下良好第一印象的方法。故选E。]
2．F [上文“Body language can convey quite a bit about how you feel in a given situation．A few tips to consider: open up your posture, make some eye contact and listen intently．”具体建议了三个有助于留下好的第一印象的肢体语言，选项F承接上文，说明以上所列的事情不需要都做，引出下文“If eye contact feels uncomfortable，try just focusing on your posture．”具体解释不需要全做以上所列的事情。故选F。]
3．C [下文“People generally want to know they can trust you．”说明别人想知道你可不可以信任，选项C引领下文，和下文存在因果关系，对别人要真诚，因为他们想知道你是不是值得信任。故选C。]
4．D [小标题“Dress for the occasion”和上文“There's nothing wrong with expressing yourself through your clothing．Just know that certain situations do call for a slightly more formal look．”说明要注意着装，某些场合的着装需要正式一点，选项D承接上文，继续说明合适的着装问题。故选D。]
5．G [小标题“Make small talk”说明本段话题与闲聊有关，选项G承接标题，说明有些闲聊的话题不太重要，看起来很无聊，引出下文“But it can often pay off when it comes to leaving a positive impression．”和后句构成转折语义，说明这些看似无聊的闲聊话题也是很有用的。故选G项。]

Ⅳ．阅读七选五
Several factors can influence your first impression of someone，including their physical features，voice and speech，surrounding environments，etc．It takes time to get to know personal characteristics that really convey(传达) someone's nature． 1 These tips can help．
Stay conscious(有意识的) of body language
Body language can convey quite a bit about how you feel in a given situation．A few tips to consider: open up your posture(姿势)， make some eye contact and listen intently． 2 If eye contact feels uncomfortable，try just focusing on your posture．
Show your interest
Expressing interest in what someone has to say can help boost your chances of making a good impression．Try a thoughtful comment that keeps the conversation moving and makes it clear that you've been paying attention． 3 People generally want to know they can trust you．
Dress for the occasion
Previous research suggests that body language plays more of a part in first impressions than clothing．But your personal style can play a role，too．There's nothing wrong with expressing yourself through your clothing．Just know that certain situations do call for a slightly more formal look． 4
Make small talk
5 But it can often pay off when it comes to leaving a positive impression．Even simple comments，like “I really like this new professor” or “Those are great shoes”，can start a conversation they'll remember later．
While a first impression can set the tone(基调) for future interactions，it's also worth keeping in mind that first impressions are largely unconscious．Just approach every new meeting with kindness，compassion，and a willingness to grow．
A．What about learning a lesson from it at present
B．It's all too easy to accidentally say something inconsiderate．
C．And keep any comments or praise you offer honest and genuine．
D．Besides，the “right” dress doesn't always have to be fancy or new，either．
E．Are you in search of ways to leave the most favorable first impression possible
F．You don't need to do all of the above every time you're interacting with someone．
G．Small chat about the weather or other everyday topics can sometimes seem boring．
