There are many superstitions(迷信) in Britain, but one of the most widelyheld is that it is unlucky to walk under a ladder—even if it means stepping off the pavement into a busy street!
①Walking under a ladder
If you must walk under a ladder you can avoid bad luck by crossing your fingers and keeping them crossed until you've seen a dog. Alternatively, you must lick your finger and make a cross on the toe of your shoe, and not look again at the shoe until the mark has dried.
②Umbrella
Another common superstition is that it is unlucky to open an umbrella in the house—it will either bring misfortune to the person that opened it or to the household. The superstition could date from the old time when its purpose was to act as a sunshade. If opened indoors, it might be considered to be an attack on the sun. Anyone opening an umbrella indoors in fine weather is unpopular, as it inevitably brings rain!
③Number 13
The number 13 is said to be unlucky for some, and when the 13th day of the month falls on a Friday, anyone wishing to avoid an inauspicious event had better stay indoors.
④Seven years bad luck
The worst misfortune that can befall you is caused by breaking a mirror, as it brings seven years of bad luck! The superstition is supposed to have originated in ancient times, when mirrors were considered to be tools of the gods.
⑤Black cat

Much meaning can be conveyed, clearly, with our eyes, so it is often said that eyes can speak.
Do you have such kind of experience? In a bus you may look at a stranger, but not too long. And if he is sensing that he is being stared at, he may feel uncomfortable.
The same in daily life. If you are looked at for more than necessary, you will look at yourself up and down, to see if there is anything wrong with you. If nothing goes wrong, you will feel angry toward others’ stare at you that way. Eyes do speak, right?
Looking too long at someone may seem to be rude and aggressive. But things are different when it comes to stare at the opposite sex. If a man glances at a woman for more than 10 seconds and refuses to move his gaze, his intentions are obvious, that is, he wishes to attract her attention, to make her understand that he is admiring her.
However, the normal eye contact for two people engaged in conversation is that the speaker will only look at the listener from time to time, in order to make sure that the listener does pay attention to what the former is speaking, to tell him that he is attentive.
If a speaker looks at you continuously when speaking, as if he tries to dominate you, you will feel uncomfortable. A poor liar usually exposes himself by looking too long at the victim, since he believes in the false idea that to look straight in the eye is a sign of honest communication. Quite the contrary.
In fact, continuous eye contact is confined to lovers only, who will enjoy looking at each other tenderly for a long time, to show affection that words cannot express.
Evidently, eye contact should be done according to the relationship between two people and the specific situation.
1.Which of the following behaviors is proper according to the passage?
A. To the opposite sex, stare at him or her.
B. To a stranger, avoid looking at him or her.
C. In a conversation, look at the listener all the time.
D. Make eye contact depending on the relationship and different situations.
2.If two persons exchange eye contact gently for long, what is probably their relationship?
A. Boss and employee. B. Lovers.
C. Teacher and student. D. Strangers
3.What’s the best title of the passage?
A. Don’t stare at others B. Body language is important
C. Eyes can speak D. Eye contact benefits you

In 2017, AlphaGo defeated Chinese player Ke Jie to become the world’s No 1, ending thousands of years of human dominance（控制）in the game. AlphaGo is an artificial intelligence（AI）Go-playing program.1.
Artificial intelligence（AI）is usually defined as the science of marking computers do things that require intelligence when done by humans.2.These include learning, reasoning, problem-solving, perception, and language-understanding.
3.In fact we are increasingly depending. upon computer-based artificial intelligence. As Charlie Qrtiz said, head of AL at the Massachusetts-based software company Nuance Communication, “It has opened a window for us.”Smartphones, self-driving cars, intelligent robots，etc. are constantly coming into our life. According to a recent survey, half of the world’s AI experts believe human level machine intelligence will be achieved by 2040. This will open up huge possibilities for the enrichment of mankind, from tackling climate change and treating disease to labour- saving devices.
4.Physicist Stephen Hawking last year warned that unless we take care, board games might be the least of it. “The development of full artificial intelligence could mean the end of the human race.”5.They believe AlphaGo’s victory is a reminder of how fast the world is overcoming the obstacles in the way of AI, and its distribution in the world about us. Although there may yet be no evidence that computers will ever shake off their human masters, we should still treat these development with the humility and caution they deserve.
A. Other scientists have also expressed the concern.
B. Artificial intelligence has both advantages and disadvantages.
C. Defeating a human Go master is not the only thing AI can do.
D. Artificial intelligence will bring us disasters instead of benefits.
E. It was designed by an American Artificial intelligence company.
F. Not all experts hold the optimistic attitudes to the development of AI.
G. Research in AI has so far focused on some special fields of intelligence.

When a leafy plant is under attack, it doesn’t sit quietly. Back in 1983,two scientists,Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm.What the plants pump through the air is a mixture of chemicals known as volatile organic compounds,VOCs for short.
Scientists have found that all kinds of plants give out VOCs when being attacked .It’s a plant’s way of crying out.But is anyone listening?Apparently.Because we can watch the neighbours react.
Some plants pump out smelly chemicals to keep insects away.But others do double duty .They pump out perfumes designed to attract different insects who are natural enemies to the attackers.Once they arrive,the tables are turned .The attacker who was lunching now becomes lunch.
In study after study,it appears that these chemical conversations help the neighbors .The damage is usually more serious on the first plant,but the neighbors ,relatively speaking ,stay safer because they heard the alarm and knew what to do.
Does this mean that plants talk to each other? Scientists don’t know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to “overhear” the cry. So information was exchanged, but it wasn’t a true, intentional back and forth.
Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear. Our senses are weak. There’s a whole lot going on.
1.What does a plant do when it is under attack?
A. It makes noises. B. It gets help from other plants.
C. It stands quietly D. It sends out certain chemicals.
2.What does the author mean by “the tables are turned” in paragraph 3?
A. The attackers get attacked.
B. The insects gather under the table.
C. The plants get ready to fight back.
D. The perfumes attract natural enemies.
3.Scientists find from their studies that plants can .
A.predict natural disasters B.protect themselves against insects
C.talk to one another intentionally D.help their neighbors when necessary
4.what can we infer from the last paragraph?
A.The word is changing faster than ever.
B.People have stronger senses than before
C.The world is more complex than it seems
D.People in Darwin’s time were more imaginative.

Recent studies have shown that there is a link between anxiety and intelligence and it is a positive one.Fear allows you to react to a potential threat in good time.Being too happy all the time means that you don't think about potential problems.1.But the response means that their imagination is highly active.An active imagination keeps you safe from threats.

根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month. 1
One idea is that sleep helps us strengthen new memories. 2 We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.
Support is growing for a theory that sleep evolved so that connections between neurons(神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day. 3
Now we have the most direct evidence yet that he is right. 4 The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.
If Tononi’s theory is right, it would explain why, when we miss a night`s, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.
Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. 5 “You keep what matters,” Tononi says.
A. We should also try to sleep well the night before.
B. It’s as if the brain is preserving its most important memories.
C. Similarly, when people go for a few days without sleeping, they get sick.
D. The processes take place to stop our brains becoming loaded with memories.
E. That’s why students do better in tests if they get a chance to sleep after learning.
F. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.
G. Tononi’s team measured the size of these connections, or synapses, in the brains of 12 mice.

Dear Peter,
How times flies! It had been almost a year since you left China to Sweden. During your home stay at my home, we had such wonderful time that it seemed as if everything had been happened yesterday. I have been long to hear all about you and missing you so much. Fortunate, I was selected as one of the student representative to pay a visit to your school. The visit will last on July 7th to 20th. And as a super soccer fan, I’d really love to visit our local soccer club.
I can’t wait for the day to come where I can see you.
Yours,
