We shouldn’t judge a person by their appearance but we do. In fact, the experts say that when we meet someone for the first time we make a decision about what that person is like in three seconds. 1. One of the most important things we look at is clothes, but it isn't the brand of clothes that people wear that is important. The important thing is to wear the right clothes for the right places.
Schools have always understood this and a lot of them ask their students to wear a uniform. Why? A lot of teachers think a uniform makes students feel that they are part of their school and that their form helps them to be serious about their studies. 2. If all the students wear uniforms, they can’t judge each other because of their clothes. It also stops gossips about who or what is fashionable.
3. We all have fixed ideas about what the people in a certain job should wear. If we visit a doctor, we hope to see respectable clothes under the doctor’s white coat. 4. Police officers wear uniforms to make themselves easily identifiable to non-police officers. In fact, a lot of companies have dress codes for their staff because they know that the customers hope to see them dressed in certain types of clothes.
But can our clothes really tell people what we are like? 5. When people see us in the right clothes, they think we are serious about what we are doing. Furthermore, if we are clean, smart and polite, people will believe us a lot.
A. Maybe not, but they can show our attitude to what we are doing at the moment.
B. Some of the teachers hold different opinions.
C. But what do we look at?
D. Teachers say that uniforms can help in other ways too.
E. Our clothes stand for our attitude.
F. However, it is not only schools that want people to dress in a certain way.
G. When we go into a bank we expect the staff to wear suits or dresses.
Today，we are constantly bombarded with media reports about research on the right diet to follow to help us maintain a healthy lifestyle or lose weight—but it’s hard to know which one to pick and，once chosen，it's harder still to stick to it.And now there’s another choice to get our teeth into.
A flexitarian(弹性素食者)diet involves eating plant—based foods and only occasionally eating meat and fish.This eating style allows you to supplement some ingredients that you wouldn’t get in a stricter vegan(素食主义者)diet—another trend growing in popularity.And like veganism，flexitarianism isn’t about eating carefully to help you lose a few pounds—it’s something people choose for ethical reasons，to help the planet.And a study into the global food system and how it affects the climate，has found that eating mainly plant-based foods is one of three key steps towards a sustainable future for all by 2050.
This research found that food waste will need to be halved and farming practices will also have to improve to achieve this.But without a single solution，a combined approach is needed.Dr Marco Springmann from the University of Oxford was one of the lead authors of the report.He told the BBC“We really found that a combination of measures would be needed to stay within environmental limits and those include changes towards healthier more plant—based diets.”
But whereas vegans think it's wrong for animals to be killed for food，flexitarians believe eating meat once in a while is acceptable.And Dr Springmann agrees—as long as we“treat it as a luxury，it’s probably OK but you shouldn’t have more than one serving of red meat，which includes beef and pork，per week.”And here’s another fact to digest:If we moved to this type of diet，the study found that greenhouse gas emissions from agriculture would be cut by more than half.

Mosquitoes have an extraordinary ability to target humans far away and fly straight to their unprotected skin. Regrettably, mosquitoes can do more than cause an itchy( 发痒的)wound. Some mosquitoes spread several serious diseases, including Dengue, yellow fever and malaria.
Over one million people worldwide die from these diseases each year. New research now shows how mosquitoes choose who to bite.
Mosquitoes need blood to survive. They are attracted to human skin and breath. They smell the carbon dioxide gas, which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.
But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects, with even smaller brains, use three senses to find a blood meal.
Michael Dickinson's team used plumes( 烟 )- a material that rises into the air of carbon dioxide gas into a wind tunnel. They then used cameras to record the mosquitoes. The insects followed the plume.
Then, the scientists placed dark objects on the lighter colored floor and walls of the tunnel. Mr Dickinson said, at first, the mosquitoes showed no interest in the objects at all. "What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel, But the moment they get a hit of CO2, they change their behavior quite obviously and now would become attracted to these little visual spots.
This suggested to the researchers that a mosquito's sense of smell is more important in the search for food. Once mosquitoes catch a smell of a human or animal, they also follow visual signals.

“Attention, everyone!” Miss Dalrymple looked at her class of ten-year-old. “Today we are going to create a special card for Father's Day, which falls on this weekend.” Then she busied herself handing out the paper and art materials to her noisy pupils.
They were a mixed punch. Some came from the rich side of the town, but the majorities were from parents who struggled to get jobs. So she had not been eager to carry out this activity.
“Think about all the things that your dad does that make him special,” she said loudly as she approached the last table. “You can write a poem or short story thinking of the positive characteristics that make your dad special. The written part of this activity should be completed before you start to decorate your card.”
Andrew looked at the blank page. He had never met, spoken to, or been hugged by his dad, so how could he write about him? Once when he was looking in his grandma's photo box, he had seen an old black and white photo but it was badly creased( 弄 皱 ) and difficult to recognize any clear features. She had quickly taken it from him and buried it deeply among the rest, never to be found again. After thinking for a while, he wrote:
Dear Dad,
You are a person I do not know and would probably not recognize as I only saw an old photo of you a long time ago. I think and wonder about you often, especially when I have no one to talk to about the Saturday fixtures( 体育 活 动 ). One day when I grow up I will do an Internet search to find you, but I am not sure whether I will be successful as several attempts by the Child Support Agency have not been successful. Happy Father's Day, Dad.
Love,
Andrew
