Ⅲ．【参考范文】
One day，an unexpected visitor arrived at my hospital bedside． It was Lucy，with her familiar smile and a bag full of goodies．She looked at me with those warm，comforting eyes and said，“Hey，how's it going？I've brought you some of your favourite books and snacks．I knew you're probably bored here，so I thought we could catch up and maybe even read a chapter together．” Her words were like a ray of sunshine breaking through the darkness of my hospital room．I felt my spirits lift as we talked and laughed，sharing stories of our old adventures and dreaming up new ones．Lucy's visit was a reminder that even in the darkest times，friends can bring light and hope．
With Lucy's company and doctors' proper treatment，things began to improve． My strength slowly returned，and I was able to spend more time out of bed．Lucy and I continued to bond，sharing our thoughts and fears about the future．She was always there to listen，to offer advice，and to remind me that I was not alone．Slowly but surely，I began to regain my independence．With Lucy's unwavering support，I was able to face my illness with courage and determination．I knew that no matter what challenges came my way，I had a friend who would stand by me until the end．

Ⅰ．阅读理解(共8小题；每小题2.5分，满分20分)
A
Weed control is essential for improving crop yields，but it is increasingly difficult．Some weeds are becoming resistant to weed killers，which face stricter regulations and，in some cases，are being banned．On top of that，many consumers want organic produce．Worker shortage means that using a weed puller behind a big farm machine is expensive，time-consuming，and difficult．
Weeding is a chore that most farmers would happily hand to robots．But for a robot to do the job properly，it must be able to distinguish a weed from what is being grown．This is becoming easier with advances in computer vision．Some phone apps can now identify a plant from just a photo．Robots equipped with cameras will weed and perform various tasks automatically．
Having spotted a weed，several ways exist to try to kill it．The Small Robot Company's weeding robot，called Dick，uses electricity to kill them．The robot's wheels work like an electrode (电极)to contact the ground while another electrode is moved to touch the plant．This allows energy to flow through the plant，generating heat that effectively boils the plant's cells，killing it instantly．The pieces of the plant can then be left to naturally break down into the soil．
Dick will work with Tom and Harry，all of them electrically powered．The idea，says Ben Scott-Robinson，is that Tom will routinely scan fields to a level of detail of just a few centimeters．Using its cameras and other sensors，the thin four-wheel-drive machine can map the health of every plant，along with soil conditions．When weeds appear，Dick will be sent to kill them．Harry，the third robot，is under development for tasks such as seeding and applying precise levels of fertiliser to each plant．Tom will go into commercial production in August．Unlike many vegetables，cereals (谷类)are grown more densely in rows，which makes the mechanical hoeing (锄)of weeds tricky．Armed with Tom's methods，Dick should be able to kill grassy weeds in cereals accurately．
1．What is the challenge in weed control
A．Weeds are growing too fast．
B．Robots are not capable of weeding．
C．Organic produce dominates the market．
D．Weed killers are facing stricter regulations．
2．What can be inferred about the use of robots in farming
A．Robots can be farmers' good helpers．
B．Robots are only able to harvest crops．
C．Robots can predict the crops' growth．
D．Robots are too expensive for most farmers．
3．What is Tom's role in the Small Robot Company's robot system
A．It is a mechanical hoe for cereals．
B．It scans fields and maps plant health．
C．It is under development for future tasks．
D．It is responsible for seeding and fertilising．
4．What does the text mainly talk about
A．The invention of a new type of robot．
B．The development of organic farming．
C．The challenges and solutions in weed control．
D．The increasing resistance of weeds to weed killers．
B
Summer tomatoes are filled with promise：the red color；the grassy tomato-leaf smell；the expectation of a mouthful of sweet-salty tomato dishes．But supermarket tomatoes do little more than disappointment．How can a fruit with so much potential constantly taste slightly juicy at best and a globe of cardboard at worst
We know that modern tomatoes sold at the supermarket are picked green and grown for pest resistance，shipping，and shelf life and that the agriculture industry creates produce designed for profit，not flavor．Do these the factors contribute to the tomato's poor taste
But even when allowed to ripen (成熟)before they are harvested and shipped with great care，modern tomatoes are still tasteless．When researchers looked into this tomato matter，they uncovered a fascinating genetic cause for the fruit's poor taste．It is a gene mutation (基因突变) discovered accidentally around 70 years ago，onto which tomato growers quickly relied．In fact，now the mutation has been grown into nearly all modern tomatoes by design．
Why？It makes them a uniform and attractively red when they are ripe．Unfortunately for tomato lovers far and wide，the red-making mutation stops the activeness of an important gene responsible for producing the sugar and smell that are essential for a good smelling and flavorful tomato，as reported in the paper，which was published in the journal Science．When the researchers “turned on” the gene that had stopped working，the fruit had 20% more sugar and 20－30% more carotenoids (类胡萝卜素)when ripe．Yet the fruit's non-uniform greenish color suggests that mainstream growers will not be following suit anytime soon．
However，for anyone with a nearby farmer's market，a supermarket that offers traditional produce，or a garden in the back，there is another choice instead of cardboard-flavored tomatoes．Traditional tomatoes and wild species have not had the basic parts of tomatoes taken out of them by selective growing—so shop for those or grow them yourself．They may not look like the a perfect fruit in your mind，but they actually taste like tomatoes．
5．Why is a question raised at the end of paragraph 1
A．To draw a conclusion from comparison．
B．To introduce the topic．
C．To express disappointment at supermarket tomatoes．
D．To encourage readers to take action．
6．Why are modern tomatoes tasteless
A．They are affected by a gene mutation．
B．They have ripened when picked．
C．They are treated with chemicals for shipping．
D．They are kept on the shelf for too long．
7．What needs improvement as for the tomatoes the researchers grew
A．Size．　　　　　　　 B．Production．
C．Color． D．Taste．
8．What is the best title for the text
A．How Do Modern Tomatoes Differ from Traditional Ones
B．Why Are Modern Tomatoes Tasteless
C．How Can We Choose Juicy Tomatoes
D．Why Do People Prefer Traditional Tomatoes

Ⅲ．读后续写(满分25分)
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
Lucy and I met in the ninth grade．Until then，I had a few good friends with whom I shared many of the same interests，but never in my life had I experienced a friendship quite like the one I shared with her．
Lucy and I shared everything．At times it even seemed like we shared a brain．Lucy and I both had a thing for taking photos of our shadows in the moonlight．Some nights we would keep away from everyone else，and walk around school，the park，even train tracks with our cameras—searching for the perfect shot of our shadows cast on the sidewalk beside us．
A few months before I met Lucy，I was diagnosed (诊断)with a rare nervous system disease that would progress if left untreated．I was misdiagnosed for months．Consequently，a lot of time was wasted on the wrong treatments and I was getting worse and worse．Lucy was the first friend I ever told about my situation．
“Eventually I might not be able to walk，to be in the sun，to digest food，or to eat like a normal person．Or worse，” I said as we sat on a bench one day after school．She was quiet for a moment．
“Well，if you can't walk，I'll push you and if you can't eat，I'll have a food fight with you anyway，and if you become allergic to light we'll still be able to go shadow-hunting．I'll be your emotional sunscreen—SPF (防晒指数)1，000．”
“My SPF 1，000，huh？”
“Yup，” she laughed．
I hugged her．“Thank you．”
Days turned into weeks，weeks turned into months and my health worsened．It was getting increasingly difficult for me to get around．Lucy was there with me，every “step” of the way．Finally，things got bad enough that I was forced to leave school．Hospital became my home away from home and I was often there for months at a time．I was very sick and unable to stay in contact with friends，even Lucy．Though I had a nurse to take care of me，I felt lonely．I needed someone to talk to，a friend．
注意：续写词数应为150个左右。
One day，an unexpected visitor arrived at my hospital bedside．
With Lucy's company and doctors' proper treatment， things began to improve．
