Looking forward to your reply.
It’s necessary to revise(复习) after lessons so that you can really understand, remember and use what you have learned. It is also important to revise before exams. 1.
Find Your Place. To revise for an exam, you must first find a quiet and relaxing environment. 2. It should also be a place where you will not be disturbed.
Take Your Time. It’s a good idea to make revising part of your weekly routine. The best way to do this is to revise every school day. 3. Make sure that you study for no more than two hours every time, and that you take a little rest every half hour or so. This will keep you fresh and able to take in information.
Stay Organized. 4. If you are taking notes, organize them by subject, topic and date. That way when you have an exam, you can easily find the right notes to study to help you prepare.
5. At the end of every revision, review your notes carefully to check that you have understood what you have learned. You may also consider writing out revision cards. You can then use these as summary of the subjects that you have learned.
A.Get Ready.
B.Check Your Progress.
C.It takes time to learn a new language.
D.But don’t revise for too long at a time.
E.Here is some advice on how to revise well.
F.A place where you feel comfortable works best.
G.It is helpful to set up a system so you are organized.
Nao, the first robot able to show feelings, has been created by a European research team. When Nao is sad, he lowers his head and looks down. When he’s happy, he raises his arms for a hug. Nothing is out of the ordinary, except that Nao is a robot.
“We’re modeling the first years of life,” says Lola Canamero, a computer scientist at the University of Hertforshire. “The feelings are shown through physical gestures and body movements rather than facial or verbal (言语的) expressions.”
In the future, says the scientist, robots are likely to act as companions, provide support for old people, and help people shop online. In such uses, the display of feeling will be important in making the interactions (交往) more natural and comfortable.
Nao has been programmed to copy the emotional skills of a one-year-old child. It can memorize faces, and knows the basic rules of good and bad. Based on these it can decide how to react to what is going on. The actions going with each feeling are pre-programmed, but Nao decides for itself when to display them.
Nao is also programmed to have different personalities. A more independent robot is less likely to call for help when exploring a room, while a more fearful robot will show distress if it finds something in the room that may be harmful.
Canamero’s team will take its emotional programming forward into medical applications. Part of the project will look at ways to use robots in hospitals to support the roles of doctors, nurses and parents. Children might find that a small, friendly-looking robot that can understand their emotional states makes them less anxious. “We want to explore different roles—the robots will help the children to understand their treatment and explain what they have to do. We want to help the children to control their anxiety.” she says.
1.According to the text Nao_______.
A.displays different feelings in different situations
B.is able to copy adult emotional displays
C.can remember people’s feelings
D.learns feelings from facial expressions
2.What can we learn from the text?
A.Scientists worked on facial and spoken expressions to create Nao’s emotions.
B.The time when Nao displays feelings has been pre-programmed.
C.Emotional programming is used in medicine production.
D.Robots with emotional skills can help children feel more comfortable.
3.What can’t robots do in the future according to the scientist?
A.They can work as your companion.
B.They can aid old people .
C.They can shop with you.
D.They can show their feelings.
4.What is the text mainly about?
A.The relationship between humans and robots.
B.The roles that robots play in different fields.
C.The first robot able to show feelings.
D.The long history of robots.
Smoking is harmful. But as soon as you quit the habit, everything will be OK, right? Wrong.
New research has found that even if you give up smoking, the damage it has done to your genes will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed－a number that is one-third of known human genes.
According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.
When you stop smoking, a lot of these genes will return to normal within five years.
This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years, It’s almost like leaving a footprint on wet cement (水泥)－it will always be there, even when you’ve walked away and when the cement becomes dry.
Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.
1.The purpose of Paragraph 1 is to______ .
A.raise a question B.give an example
C.make an argument D.show the main idea of the passage
2.Most genetic changes happen because of______ .
A.people’s condition at birth B.environmental pollution
C.heart disease and cancer D.people’s bad living habit
3.The underlined word “it” in Paragraph 5 refers to______ .
A.the footprint B.the cement
C.the harmful effect D.the genetic change
4.Which of the following statements is true?
A.The findings are the fruit of more than three years’ research.
B.The findings have prevented more people from starting smoking
C.The findings offer evidence that a damaged gene can heal itself.
D.The findings help to find cures for genetic damage caused by smoking.
