1 . For some people charm (吸引力) is a natural gift, but for others being charming is a skill that they need to acquire in order to survive. If you want to charm someone, here are some ways on how to do it.

1.     1     In order to charm someone, you must learn some facts about that person. Determine what his likes and dislikes are. Then try to find the person’s soft spots. In this way, you can easily avoid the things that he doesn’t like and put an effort to show that you are interested in the things he likes.     2    

2.     3     Eye contact is one of the best ways to connect to a person. It helps you create an image that you are confident with yourself and show that you are interested in him. By establishing eye contact with the person you want to charm, you are actually starting a conversation with him.

3. Show respect. By showing respect, you are expressing sincerity to that person. Learn how to politely introduce yourself. You don’t want to create an impression that you are overconfident. A handshake may be the most common way to do it. However, other traditions involve other forms of introductory gestures.     4    

4. Always smile. Smiling is one of the basic ways to charm a person. By smiling a lot, you are creating a positive image for the person you wish to charm. Smiling is also a way of showing that person how glad you are to meet him. Remember to show a sincere and honest smile.     5     Faking a smile can make the person you want to charm think that you are not really interested in meeting him.

2 . Darwin was not a bright boy. He was much slower than his younger sister, and he was in many ways a naughty boy. However, at the age of eight he was trying to make out the names of all plants he saw, and he was busy collecting all sorts of things and he even imagined producing coloured roses by watering them with certain coloured liquids. Once he read the book Wonders of the World, he wished to work wonders himself some day.

One summer vacation Darwin became a great collector of beetles (甲虫). At that time he only collected them but made no scientific study of them. One day on tearing off the bark (树皮) he saw some unusual beetles, and seized one in each hand, then he saw a third and new kind, which he didn’t want to lose, so he put the one that he held in his right hand into his mouth. But it sent out some gas, which burned his tongue. He was forced to spit it out. It was lost, so was the third one.

Darwin accepted the offer by the navy (海军) to go on a voyage to explore the Southern Sea in the name of the government on a warship at the age of twenty-two. He was on board for five years. And during the long voyage he collected a great many of facts in Natural Science.

5 . It was an extremely busy day. I was so tired of my life that I was getting a little ________ with myself and everyone around me. On my way home, I ________ my old friend Paul in the street. He looked happy and ________ me to his home for dinner. We had not seen each other for many years, so ________ I was tired I accepted his invitation.

As we entered the door of his house, Paul started ________ “I have a dream, a song to sing, to help you ________ everything.” I felt ________ his behavior, but in no time I understood. Two ________ walked to Paul and hugged him. They couldn’t walk ________ or speak clearly, but their faces were full of ________ and sang the same song.

We talked about our ________ and work, and I learned from Paul that his daughters were born as “special children”. They were mentally changed. Their mother ________ years ago. Paul was both mother and father to his beautiful daughters. But Paul said he was ________ that the little angels were together with him and that ________ could stop him from living actively.

That night, we ________ a lot, and his happy smiles made my anger and ________ fade. I forgot how many times I   ________ about my life and my work, but Paul’s life was a(n) ________ to me. The man smiled at his life and treated any trouble as a________of life. I owe my thanks to Paul, for he taught me to deal with life ________ and move on.

7 . In 2019, I went on a winter break trip with my family. One of our _________ was London. The first thing that I _________ when I landed in London was the weather. It was too _________ for my liking as it required me to wear a thick jacket.

After some _________ using a map of London, we decided to go to Buckingham Palace first.

Buckingham Palace was one of the _________ of a “hop-on, hop-off (随上随下)” bus that we took. The palace itself didn’t look very big or impressive from the entrance _________ it got much more impressive when you entered the gates.

While continuing on the “hop-on, hop-off” bus, we _________ the London Bridge, which I didn’t notice until the driver pointed it out to me. While it felt kind of special to be driving on such an iconic (符号的) bridge, the _________ was not as cool as one would imagine it to be.

Besides its history, this bridge was just another bridge that _________ two masses of land, something that pretty much all __________ do.

When we __________ Big Ben, we decided to hop off the bus and take some __________. Big Ben was a pretty __________ experience for me. In many pictures of London, Big Ben is a very visible (看得见的) building in the skyline, and it was very nice for me to see the clock tower __________. I am a big fan of skyscrapers (摩天大楼) and skyscraper-like buildings so this clock tower certainly caught my __________.

10 . The second experiment on how to grow crops on Mars and moon soil simulant(模拟装置)has given a surprising outcome. As a result of what the researchers of Wageningen University & Research center in the Netherlands learned from their first experiment, they were able to grow ten different crop species. Tomatoes, peas, rye, garden rocket, radish and garden cress were harvested.

A few improvements have been made since the first experiment. Researcher Wieger Wamelink said, “We used trays instead of original small pots and added organic material (fresh cut grass) to the Mars and moon soil simulant. This solved the problem we had with watering in the first experiment and also added manure(肥料)to the soils.” In particular, the crop growth on the moon soil simulant showed improvement. While in the first moon soil experiment most plants died, in the next round they flourished, and the researchers could harvest from the same species as on the Mars soil simulant and the Earth potting compost(混合肥料)control.

The production of biomass(生物量)on the Mars soil simulant was lower than on Earth control, but it was a minor difference and caused by one of the trays that showed less growth. It was also not statistically different from the Earth control. “That was a real surprise to us,” comments Wamelink. “It shows that the Mars soil simulant has great potential when properly prepared and watered. The biomass growth on the moon soil simulant was less than on both other soils, about half of the biomass. Only the spinach(菠菜)showed poor biomass production.”

Although the researchers harvested several eatable crops, they did not eat them. The soils contain heavy metals like lead, arsenic and mercury and also a lot of iron. If the components become available for the plants, they may be taken up and find their way into the fruits, making them poisonous. Further research on this is necessary and that is one of the reasons why a crowdfunding(众筹)campaign has been started to finance the third experiment that will be all about food safety. If the crops prove to be safe enough to eat, the funders will be invited for dinner where a ‘Martian meal’ will be served that includes the harvested crops; at least for those who dare!
