Four Best Plants to Give as Gifts
Choosing a gift for someone is always a challenge．Giving plants is one way to try if the recipient is already a plant lover．Here are some sure to impress as thoughtful gifts．
Jade Plant
The jade plant is a large succulent(肉质植物) that makes a perfect gift for someone who's mastered parenting succulents．With a woody stem(茎)，it looks like a tree once growing tall enough．Besides occasional watering and a bright window，the jade plant has few other requirements．A good challenge for ambitious owners is to regularly cut off its heavy leaves to reduce weight．
Christmas Cactus
This is a succulent with eye catching flowers that appear in winter．You might assume it a picky plant，but nothing could be further than the truth．It prefers bright，indirect light and grows well in average potting soil．This plant prefers a steady watering schedule，especially in winter．To encourage more growth，plant it in a hanging container that allows its branches to hang down．
Paperwhite
Some people just aren't interested in keeping houseplants around long term，and paperwhite flowers are an excellent gift for anyone you know who fits this mould．Paperwhites grow from bulbs(鳞茎) and will produce flowers out of season．The roots need to be kept relatively damp，but once they are blooming(开花)，there's not much that can go wrong．They can be replanted outside after they have run their course．
Corn Plant
The corn plant is forgiving of variable light conditions and watering routines．It grows slowly，but can reach a height of four to six feet，and can make an impressive floor plant．Its leaves turn paler in direct sunlight to reflect the extra light，and darker green in shady conditions to maximize sunlight absorption．
1．Which plant requires practised gardening experience
A．Jade plant．　　 B．Christmas cactus．
C．Paperwhite． D．Corn plant．
2．How can we help a Christmas cactus grow well
A．By replanting it outside before blooming．
B．By watering it regularly during blooming．
C．By cutting off most of its heavy leaves．
D．By making its branches grow upwards．
3．What affects the colour of leaves of a corn plant
A．The frequency of watering．
B．Its flowering time．
C．Its rate of growing．
D．The amount of sunlight．
B
One morning，Ann's neighbor Tracy found a lost dog wandering around the local elementary school．She asked Ann if she could keep an eye on the dog．Ann said that she could watch it only for the day．
Tracy took photos of the dog and printed off 400 FOUND fliers(传单)，and put them in mailboxes．Meanwhile，Ann went to the dollar store and bought some pet supplies，warning her two sons not to fall in love with the dog．At the time，Ann's son Thomas was 10 years old，and Jack，who was recovering from a heart operation，was 21 years old．
Four days later Ann was still looking after the dog，whom they had started to call Riley．When she arrived home from work，the dog threw itself against the screen door and barked madly at her．As soon as she opened the door，Riley dashed into Jack's room where Ann found Jack suffering from a heart attack．Riley ran over to Jack，but as soon as Ann bent over to help him，the dog went silent．
“If it hadn't come to get me，the doctor said Jack would have died，” Ann reported to a local newspaper．At this point，no one had called to claim the dog，so Ann decided to keep it．
The next morning Tracy got a call．A man named Peter recognized his lost dog and called the number on the flier．Tracy started crying，and told him，“That dog saved my friend's son．”
Peter drove to Ann's house to pick up his dog，and saw Thomas and Jack crying in the window．After a few moments Peter said，“Maybe Odie was supposed to find you，maybe you should keep it．”
4．What did Tracy do after finding the dog
A．She looked for its owner．
B．She gave it to Ann as a gift．
C．She sold it to the dollar store．
D．She bought some food for it．
5．How did the dog help save Jack
A．By breaking the door for Ann．
B．By leading Ann to Jack's room．
C．By dragging Jack out of the room．
D．By attending Jack when Ann was out．
6．What was Ann's attitude to the dog according to paragraph 4
A．Sympathetic． B．Doubtful．
C．Tolerant． D．Grateful．
7．What can we infer about the dog from the last paragraph
A．It would be given to Odie．
B．It would be kept by Ann's family．
C．It would be returned to Peter．
D．It would be taken away by Tracy．
C
When it comes to entrepreneurship(企业家)，it seems like a lot of us are fond of the idea of NOT getting more education．Sure，we've all heard how Bill Gates and Steve Jobs dropped out of college to found Microsoft and Apple，respectively．A lot of would be solopreneurs(独立创业者) think this means they should take the same course，putting education by the wayside to chase their business goals．
Now，I'm not saying that you need a college degree to be a successful entrepreneur．But all too often，people take these famous examples a step too far and decide they don't need to further their education in any way．
The thing is，college isn't the only place you can get an education．Bill Gates and Steve Jobs learned a lot outside their classroom settings to turn their companies into the global successes they are today．When it comes to entrepreneurship，the most successful people are generally the ones who develop a lifelong love of learning．It's an feature worth imitating．
When we think of ‘exercise’， most of us think of sweaty people at the gym running on treadmills and lifting weights．We don't think of hitting the books．But the brain is actually a muscle too．And just like you need those physical workouts so you don't start getting saggy(松驰的) around the middle，you need to give your brain regular “workouts” that keep it active and healthy．
Contrary to popular belief，your brain doesn't stop growing after adolescence．One recent study found that the brain continues to produce new neurons associated with learning，emotion and memory throughout adulthood．Of course，the outcomes of this ongoing development depend in part on your own efforts．
If you're not feeling motivated to work out your brain，it might be helpful to consider the costs of not continuing to learn．Quite simply，the problems you have now—whether in business or other areas of your life—are going to continue to exist if you don't find new ways to approach them．The things you learn will help you discover new solutions and think more creatively．When done right，training your brain can become a lifelong habit—just like going for a morning run or hitting the gym at the end of the work day．
8．What can we learn from the first two paragraphs
A．It is no use obtaining college degree．
B．It is not necessary to further our education．
C．It is more important to chase business goals．
D．It is vital to view these successful examples sensibly．
9．What does the underlined phrase “hitting the books” mean in paragraph 4
A．Getting rid of the books．
B．Diving into the books．
C．Purchasing the books．
D．Referring to the books．
10．What can we know about the brain from this passage
A．The brain can be active by continuous learning．
B．The brain can produce new neurons all the life．
C．Working out the brain can solve all the problems．
D．Working out the brain will cost you a lot．
11．What is the main idea of the passage
A．The brain is of significance to our health．
B．Keeping reading books is highly recommended．
C．Non stop learning should be a lifelong habit．
D．It is important to develop a passion for learning．
D
Bottlenose dolphin moms adapt their individually special whistles(口哨) when their babies are nearby．This “parentese” might increase attention，bonding(联系) and vocal learning in babies，as it seems to do in humans．
During the first few months of life，each common bottlenose dolphin develops a unique tune，or signature whistle，similar to a name．The dolphins shout out their own “names” in the water “likely as a way to keep track of each other，” says marine biologist Laela Sayigh．But dolphin moms seem to adjust that tune in the presence of their babies，which tends to stick by mom's side for three to six years．
Sayigh and her colleagues analyzed signature whistles from 19 female dolphins both with and without their babies close by．Audio recordings were got from a wild population that lives near Sarasota Bay，Fla．，during catch and release health assessments that occurred from 1984 to 2018．The researchers examined 40 examples of each dolphin's signature whistle，confirmed by the unique way each vocalization's frequencies change over time．Half of each dolphin's whistles were voiced in the presence of her baby．When youngsters were around，the moms' whistles contained，on average，a higher maximum and slightly lower minimum pitch(音高) compared with those voiced in the absence of babies，contributing to an overall widened pitch range．
These whistle adjustments echo baby talk because human caregivers use real words and language，just with certain inflections(变调)，Sayigh says．Formally called child directed communication，these inflections typically involve higher pitches and a wider pitch range，like what was observed in the dolphins．“Bottlenose dolphins are a main candidate for child directed communication，” says Quincy Gibson，a marine mammal behavioral ecologist．Similar to humans，these dolphins form strong mother baby bonds and learn vocalizations．
But to confirm this study's results，scientists should analyze signature whistles of freely swimming，uncontrolled dolphin moms，notes Gibson．“We do need to look at this question in more natural and undisturbed conditions．” Still，Gibson says，“The idea that there might be similar forces driving parentese in such different species is just really cool．”
12．What can be learned about a bottlenose dolphin's signature whistle
A．It warns of danger．
B．It's voiced by females．
C．It's targeted at babies．
D．It varies individually．
13．What kind of whistle did a dolphin mom give with her babies nearby
A．Whistles with a stable frequency．
B．Whistles hard to record．
C．Whistles with a broader pitch range．
D．Whistles with a lower maximum pitch．
14．According to Gibson，the study would be more convincing if ．
A．more dolphins had been involved
B．the subjects had included different species
C．the dolphins had been studied in a large place
D．the dolphins had been studied when they were younger
15．What could be a suitable title for the text
A．Dolphins and Humans Have Much in Common
B．Bottlenose Dolphins Communicate Like Humans
C．Dolphin Moms Use Baby Talk to Bond with Young
D．Dolphins Have a Highly Advanced Spoken Language

Tips on How to Study Smarter
Having good study skills is always helpful．And it's more important in the present situation，where online classes are growing．Students are likely to learn without a teacher or parent watching over． 16 Here are some tips to develop good study skills．
●Practice，practice，practice! Musicians practice their instruments．Athletes practice sports skills．The same should go for learning． 17 In one study，students took practice tests over several weeks．On the final test，they scored better than those who studied in the normal way．
●Test yourself．Before big tests，you may often cover up the notes，and then try to recall them．This practice can help nearly everyone．You can put questions down on one side of the paper and the answers on the other side． 18 Teachers often dig deeper．They don't just ask shallow questions．
●Learn from mistakes．A secret of science: Mistakes help understanding．If you don't find out what the answer is，you're wasting your time．Checking the answers can make your study time more efficient．Check to see if you are right．You can then focus on what you get wrong． 19
● 20 Students know some good study skills，yet many of you don't actually do these things．Often you fail to plan ahead．So do make plans．And try to stick to a routine，too．For example，you can have a set time and place where you do schoolwork and study．And get enough sleep—not just the night before the test but for weeks or months on end．
A．Focus on your plan．
B．You can add more skills．
C．Make a plan and stick to it．
D．In fact，mistakes are actually a primary key to learning．
E．Try to test yourself in the way the teacher asks questions．
F．So you will have to manage your time and study more on your own．
G．If you want to be able to remember information，the best thing you can do is practice．

Every Saturday，Bibi hung out at her grandma's laundry and dry cleaning store while her mom worked．Bibi loved being with her grandma，but she wanted to do more than just draw and read．“How about I write down what people bring in and pin a number to it？” Bibi offered．With Grandma nearby，she did fine．But the next order was an enormous bedspread．Bibi checked it in，but when she went to lift it off the counter，it wouldn't move．She tried moving it，but it toppled over on her．“I'm OK！” She giggled from under the soft material．Grandma lifted the bedspread off her and smiled．“Why don't you draw for a little while，” she suggested．“You're such a good artist．”Bibi sighed．“But I wanted to help you．” Grandma didn't want her to handle the hot presser or the iron．She could put the stiff cardboard into the ready washed shirts，but that was about it．“Why don't you draw a picture of more customers coming in？” Grandma joked．“Maybe that would help！”
Bibi went outside．It was a clear fall day．The last leaves were starting their lazy drift to the ground．She spotted her babysitter，Stephanie．Stephanie was painting big letters on the window of the hardware store．“Stephanie！” Bibi called．“You're going to get in trouble．” Stephanie laughed．“The high school cheerleading(啦啦队) is painting windows for our football game next weekend．Some of the shop owners said we could．”
“Does that paint wash off？” Bibi asked．“Yep．It's just cornstarch(玉米淀粉)，soap，and food coloring，” said Stephanie．Bibi saw other kids from the high school painting designs on windows up and down the street．“GO，TIGERS！” said the window of the nail salon in huge letters．“HEAR US ROAR！” said the window of the milkshake shop．“I can help you！” Bibi called to Stephanie，her heart beating fast．“I can draw！” “Sorry，Bibi，” Stephanie said．“I'm out of paint，and I have to get home．Thank you，though！” Bibi was so disappointed．She stared at Grandma's windows．They were bare．

When she finished, Bibi went inside to get Grandma． When they came back out, a bunch of kids were gathered there．“Great job！” said one girl．“Perfect，” said another．Bibi's grandma looked up at the window to see what it was with pride．“AFTER THE GAME, BRING YOUR UNIFORMS HERE！” the window said．Bibi had drawn a picture of the team's uniforms jumping into a big tub with soap bubbles．Grandma clapped her hands and hugged Bibi．“This just might help，” she said．And after the game, it did．

36．have provided/have been providing　[考查时态、语态和主谓一致。分析句子结构可知，空处为句子的谓语动词，与主语之间为主动关系；根据“For centuries”可知，句子可以用现在完成时，也可以用现在完成进行时态，表示该动作从发生以来一直持续到现在，也有可能一直持续下去；主语为复数。故填have provided/have been providing。]
37．including　[考查非谓语动词。空处为动词ing形式短语在句中作状语。故填including。]
38．stability　[考查词性转换。分词句子结构可知，空处需要用名词作boosts的宾语。stable为形容词，其名词形式为stability。故填stability。]
39．which　[考查定语从句。分析句子结构可知，空处引导非限制性定语从句，修饰前面的一整句话，在从句中作主语，所以用关系代词which引导从句。故填which。]
40．dates　[考查时态、语态和主谓一致。分析句子结构可知，空处为句子的谓语动词。本句话陈述一般事实，所以用一般现在时态；主语为“The Hemudu site in Yuyao”，谓语动词用第三人称单数形式。故填dates。]
41．earliest　[考查形容词最高级。根据空前的the以及句意可知，这是中国已知的最早的榫卯结构，所以空处需要用该形容词的最高级。故填earliest。]
42．a　[考查冠词。a whole set of “一整套……”。故填a。]
43．to　[考查介词。根据语境以及句中的from可知，空处考查短语from．．．to．．．“从……到……”。故填to。]
44．defined　[考查非谓语动词。分析句子结构可知，空处需要用非谓语动词作后置定语。该动词和修饰的名词之间为逻辑上的被动关系，所以用过去分词作定语。故填defined。]
45．people's　[考查名词所有格。分析句子结构并结合句意可知，空处需要用名词所有格作定语修饰后面的名词。故填people's。]
