DNA is the whole"map" of the human body.It is something that all humans have，and it tells the body what to do.DNA is the reason that we look like our parents，because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time.In 1860，Mr Mendel discovered why we look similar to other people in our family.It is because of small things called "genes（基因）"in our body.In 1953，two scientists，Watson and Crick，found out that those small parts are real messages.They are written in the DNA with a special language.
In 1961，another two scientists found the first "word" that they could understand in that language.It shows how DNA tells the cell（细胞） to build its parts.So far，scientists have found all the words in the DNA map，but we do not understand what they all do.By understanding what just one "word" means，we can help to save people from several illnesses.So the more we understand ，the more doctors will be able to do.
Most people hope that this will help to make better medicine to help sick people，Other people worry that when we learn more "words" and find out more information，we will use it in the wrong way，just to make people more attractive（有吸引力的）or stop sick people getting jobs.

The local people of La Gomera can carry on conversations by whistling（吹口哨） from far away． For face﹣to﹣face conversations，they Spanish．But when they need to speak over a distance（距离），they whistle．
La Gomera is a small island．This island is almost shaped like a circle．It is very mountainous．Walking from one place to another may be a slow and difficult job． That is why whistling is so useful to the local people． A message can easily be whistled over a couple of miles， while to travel that same distance on foot might take an hour．
A good whistler can be heard and understood five miles away．His whistling can be farther away when it is windless． It is said that the record is about nine miles．Anyone who a top whistler will agree that this record is quite possible．

We always think that it's OK for us to leave our plants home during our vacation as plants won't scream like pets， right？
A recent study done by a group of scientists at the Tel Aviv University has discovered that some plants will scream when they are under stress．
The research was carried out on tomato plants and tobacco plants by cutting their stems（茎） and depriving（剥夺） them of water． A microphone was placed 10cm away from them． When their stems were cut， the plants started "screaming" between 20 and 100 kilohertz， and the scientists guess that this scream is probably meant to warn other plants nearby．
When the tomato plants' stems were cut， 25 ultrasonic（ 超声的） pain sounds were recorded in an hour， and at the same time， 15 ultrasonic pain sounds were recorded from the tobacco plants． When they were deprived of water， the tomato plants recorded even more pain sounds with 35 pain sounds in an hour while the tobacco plants recorded about 11 pain sounds．
The plants also acted differently to different kinds of stresses． For example， the tobacco plants gave out a stronger "scream"when they were deprived of water than when their stems were cut． But plants that were in no immediate（立刻的） danger gave out less than one ultrasonic sound per hour．
The group of scientists said that plants are not as quiet as we had always thought， but in fact their voices are so high﹣pitched that we just can't hear them．
Last year， another study has found out that plants feel pain when they are touched or hurt and they will give of a terrible smell．
（1）What have the group of scientists at the Tel Aviv University discovered？
A． Some plants under stress will scream．
B． Plants in danger scream to warn others．
C． Some plants under stress feel energetic．

D． 35．
（4）What can we learn from the passage？
A． Tomato plants acted the same under different stresses．

C． Plants not in immediate danger screamed most weakly．
D． Plants that felt pain screamed loudly for people to hear．
In the past， I thought I was terrible at many things， such as math， French and science． Although I was good at drawing， I wasn't the best in my art class．I wanted to find out who I was，what I liked and how I could do it better．So， that winter，I took a notebook and kept my diary． When I filled that notebook，I started another one， and then another．
Keeping a diary helps a lot． Studies have shown that people who keep a diary sleep and feel better． It helps people remember what once happened such as dreams， friendships and happiness． Writing about bad feelings can also help brains get over themand move on． Personally， I learn better about myself and my relationships with others by keeping a diary．For example，when I am fighting with my dad， I'll try writing from his point and it works! If I want to compare myself with my classmates．I'll write something like，"I might not have clear skin， but I like my eyes．"
Right about now， you might be thinking： it sounds great， but I'm not a good writer； or I'd love to keep a diary， but my handwriting is terrible． Don't worry! Keeping a diary is not like doing your homework ﹣there are no rules， so do whatever feels best．

Think about what you like to wear on the weekend.There's a good chance that you like to put on a pair of blue jeans.At any moment，about half of the world's population is wearing jeans.But according to a new study，our love for jeans may be bad for Earth.Denim （牛仔布）might be putting some sea animals in danger.
Every time we wash our jeans，tiny bits of denim will flow out of our washing machines，down into the world's rivers，lakes and oceans.
You might wonder：Isn't denim made of cotton，a natural material？How can it become a danger to nature？Well，in the process of making jeans，denim is treated with many types of man﹣made chemicals.Some improve its durability （耐用性）and feel；others give jeans their blue color.
Scientists studied the Great Lakes in America and the Arctic Ocean in northern Canada.They found denim waste in all of the samples （样本）they had collected.It is feared that the harmful chemicals in denim have spread far and wide.Scientists aren't yet sure how these chemicals might harm animals.
In the study，the scientists also washed jeans to see how many bits of denim each pair would drop per wash.The answer was frightening：About 50，000.Not all of them make their way into the environment.Wastewater treatment plants hold back 83 to 99 percent of them.This may sound pretty good.However，one percent of 50，000 bits are still 500 per wash.Now think about the number of jeans around the world and the times each of them gets washed.As a result，a large amount of denim waste still gets into the environment.
Does this mean we shouldn't wear jeans？Probably not" We need to buy fewer jeans and only wash them when we truly need to do it，" says Sam Athey，one of the scientists. " You don't need to wash your jeans after having worn them only a couple of times. "

Like you， plants need good things like food， water， and minerals in order to grow． Usually they get these important nutrients（营养） from the rich soil（土壤） in which they're planted． But there's another way to grow plants that doesn't use soil． It's called hydrogenic gardening．
"Hydrogenic" means "working with water． " In a hydrogenic garden， plants grow with their roots in water， not in dirt． The water is filled with special food for the plants that gardeners have carefully measured and prepared．
Hydrogenic plants grow quickly． In ordinary gardens， plants need time and energy to grow long roots that search the soil for food and water． In a hydrogenic garden， plants can use their energy to grow tall instead． And because there is no soil， there are no weeds and few insect pests（害虫）． Gardeners don't need to spray（喷洒） plants with dangerous chemicals． Both the plants and the environment stay healthy．
Scientists hope that， one day， hydrogenic gardens may be able to help hungry people all over the world grow enough food﹣even in countries that have bad soil， or weather that is too hot， too cold， or too dry． And astronauts hope to take hydrogenic gardens with them to the spaceship they fly to Mars， so that they will always have fresh vegetables， and the fun of growing a garden without dirt．
