4．A new study finds that plants communicate with one another to warn of danger．
We often consider plants as the furniture of the natural world．They don't move； they don't make sounds，they don't seem to act on anything．But as is often the case，plants talk to each other all the time．And the language is chemical．
Over the years，scientists have reported that different types of plants，from trees to tomatoes，give out chemicals into the air to help neighboring plants．These chemical warnings can spread information about one plant's disease or infestation（虫害），so other plants can protect themselves．But how plants receive and act on many of the information exactly is still mysterious．
In this week's Science Magazine，researchers in Japan offered some explanations．They have found out one chemical message and traced it all the way from beginning to end．
The scientists looked at tomato plants infested by a common pest（害虫）．To start out，they grew plants in two separate plastic spaces connected by a tube（管子）．One plant was infested and placed upwind and the other was uninfested and placed downwind．The downwind plants were later exposed（暴露） to the pest．The results showed that plants near sick neighbors before were able to protect themselves better against the pest．
They found one chemical appeared more often in the exposed plants．The chemical is called HexVic．The scientists discovered where HexVic come from，and put it over healthy plants．Those plants were then able to produce HexVic．Researchers made sure that uninfested plants could fight off bugs and diseases．How do they know when to protect themselves？They are warned first by their friendly plant neighbors．
It is not a simple story，and it may be happening in more plant species than tomatoes．It may also be happening with more chemical signals that are still unknown to us．In a word，we know that plants not only communicate，but also look out for one another．

62．The underlined"traced"in the fourth paragraph probably meansB here．
A．reported
B．followed
C．doubted
D．developed

5．Most people hope to have a memory which helps them succeed in study，work and life．Can memory be improved？Luckily，hundreds of studies in the past 50years have already given us a definite answer．
A healthy lifestyle keeps our brain young and memory sharp．First of all，it is necessary to have a healthy diet．Eating more food rich in B vitamins and vitamin E，such as vegetables and lean meat，helps you have a better memory．Doing exercise can keep your brain alive，too．Proper exercise provides much oxygen for the brain．Running，riding a bike，swimming and even walking two or three times a week are helpful．Moreover，getting enough sleep is important．Only when your brain gets a good rest，can it work well．The healthier your lifestyle is，the better your memory will become．But do not expect a sudden change-it takes a long time to make a difference．
Memory stills help you remember things better．The following three are the most widely used．Chunking is a way of remembering a piece of information by cutting it into small ones．For example，to memorize a ten-digit telephone number 2127983630，you can divide the digits into three groups：first 212，then 798，and lastly 3630．This method is far more effective than remembering a string of 10digits．Organization means organizing information into groups of the same kind．For example，trees，grass and flowers are plants； tigers，pandas，horses and cows are animals．Imagery is remembering newly learnt information by using your imagination and connecting it with something that you are familiar with．
However，memory skills will hardly work if you don't understand the information．What's more，only a regular review can make the memory last long．That is why students are always advised to go over what they have learnt and then use it as regularly as possible．
Human brains are like muscles that needs nutrients and exercise to become stronger．If you make a few lifestyle changes and try some memory skills，you can certainly improve your memory．
20．How many ways of keeping a healthy lifestyle are mentioned in the passage？B
A．Two．
B．Three．
C．Four．
D．Five．
21．Which of the following examples is the use of the skill"organization"？A
A．Remembering the word"sad"by putting it into the group of"feeling"．
B．Remembering the meaning of the word"red"by connecting it with"fire"．
C．Remembering a long and difficult passage by understanding its meaning．
D．Remembering the number 0708591by dividing it into 070and 8591．
22．According to the passage，why should we review what we've learnt？D
A．To use it better every day．
B．To understand it in a better way．
C．To improve memory stills．
D．To remember it for a longer time．
23．The passage is written to tell usC．
A．not everyone has a good memory
