Since March xx, Ive done 89 tripsof those , 51 have been abroad. I have 42 hours to carry stem cells（干细胞）in my little box because Ive got two ice packs and thats how long they last. In all, from the time the stem cells are harvested from a donor(捐献者) to the time they can be implanted in the patient, weve got 72 hours at most. So I am always conscious of time.I had one trip last year where I was caught by a hurricane in America. I picked up the stem cells in Providence, Rhode Island, and was meant to fly to Washington then back to London. But when I arrived at the check-in desk at Providence, the lady on the desk said:“Well, Im really sorry, Ive got some bad news for youthere are no flights from Washington.” So I took my box and put it on the desk and I said:“In this box are some stem cells that are urgently needed for a patient-please, please, youve got to get me back to the United Kingdom.” She just dropped everything. She arranged for a flight on a small plane to be held for me，re-routed(改道)me through Newark and got me back to the UK even earlier than originally scheduled.For this courier job, youre consciously aware that in that box youre got something that is potentially going to save somebodys life.21 Which of the following can replace the underlined word “courier” in Paragraph1?A. provider B. delivery manC. collector D. medical doctor22 Why does Peter have to plete his trip within 42hours?A.

Even when her daughter and son asked her to move to San Antonio to help with their children, she politely refused. Only after a year of friendly discussion did Ms. Garza finally say yes. That was four years ago. Today all three generations regard the move as a success, giving them a closer relationship than they would have had in separate cities.No statistics show the number of grandparents like Garza who are moving closer to adult children and grandchildren. Yet there is evidence suggesting that the trend is growing. Even President Obamas mother-in-law, Marian Robinson, has agreed to leave Chicago and move into the White House to help care for her granddaughters. According to a study by grandparents. , 83 percent of the people said Mrs. Robinson s decision will influence grandparents in the American family. Two-thirds believe more families will follow the example of Obamas family.“In the 1960s we were all a little wild and couldnt get away from home far enough for fast enough to prove we could do it on our own,”says Christine Crosby, publisher of Grand , a magazine for grandparents.“We now realize how important family is and how important it is”to be near them, especially when youre raising children.”Moving is not for everyone. Almost every grandparent wants to be with his or her grandchildren and is willing to make sacrifices, but sometimes it is wiser to say no and visit frequently instead. Having your grandchildren far away is hard, especially knowing your adult child is struggling, but giving up the life you know may be harder.24 Why was Garzas move a success?AIt strengthened her family ties.BIt improved her living conditions.CIt enabled her to make more friends.DIt helped her know more new places.25 What was the reaction of the public to Mrs. Robinsons decision?A17% expressed their support for it.BFew people responded sympathetically.C83% believed it had a bad influence.DThe majority thought it was a trend.26 What did Crosby say about people in the 1960s?AThey were unsure of themselves.BThey were eager to raise more children.CThey wanted to live away from their parents.DThey had little respect for their grandparents.27 What does the author suggest the grandparents do in the last paragraph?A. Make decisions in the best interests of their own.B. Ask their children to pay more visits to them.C. Sacrifice for their struggling children .D. Get to know themselves better.阅读理解。Being an astronaut sounds cool, doesnt it？In space, they get to do some pretty amazing things, like floating in zero gravity.However，there are also plenty of things that astronauts cant do because of their weightless environment, and thats very sad. Whats worse, they cant even let their sadness showbecause its impossible to cry in zero gravity.Of course, astronauts can still produce tears. But crying is much more difficult in space，reported The Atlantic in January. Without gravity, tears dont flow downward out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to gothey just stick to your eyes.In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks.“Tears，” he said, “dont fall off your eye. They just kind of stay there.”Besides making your vision unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring fort to the eyes.But thats not the case in space.The space environment dries out astronauts eyes, and when tears suddenly wet the eyes, it can cause pain rather than fort. “My right eye is painful like crazy.” Feustel told his teammate during the walk.Since gravity doesnt work in space, astronauts need some extra help to get rid of the tears.Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait“When the tears get big enough they simply break free of the eye and float around，”astronaut Ron Parise told The Atlantic.There are lots of small thingsthings like cryingthat we are so used to on Earth. We usually take them for granted, until they bee a problem in a totally different environment，like space. There, astronauts cant talk to each other directly. They also cant eat or drink in normal ways. They cant even burp(打隔), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up(呕吐) everything in their stomach，according to the UK National Space Center.Thus, perhaps its only space explorers who can honestly say：“Gravity, youre the best.”28What can we conclude from Paragraphs 2 and 3?AAstronauts are unable to feel sad in space.BAstronauts produce fewer tears in space.CTears produced in space flow down more slowly.DTears produced in space dont flow downward.29What effect do tears have on astronauts?AThey cause physical pain.BThey bring fort to them.CThey make their vision clearer.DThey float around and cause trouble.30What can the astronaut do to get rid of the tears?ARub his eyes against his helmet to let the tears float forward.BRub his eyes by hand to let the tears float around.CGet the tears big enough to fall off of his eyes.DGet the tears big enough to break away from his eyes.31Whats the last but one paragraph mainly about?ASuggestions on how astronauts can stay fortable in space.BOther basic things that are difficult to do in space.CWhy burping is impossible in space.DThings that humans cant do without gravity.阅读理解。While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for grantedbeing able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3D pizza printer!About a year ago, NASA offered $125,000 to Anjan Contractor, a 3D technology expert，to build a device(设备) that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in mon ovens.Late last year, the engineer presented a video of his first prototype(原型) that begins by creating a single slice of dough(面团) that is cooked and printed at the same time. Then es the tomato “sauce”a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesnt show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. Thats because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not.Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients (配料) and then they are reduced to the powder form. This, as you can imagine, will not be so easy.But, while the printer may not be ready for space, it certainly looks ready enough for people on earth.Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!32Why does the author mention the things that astronauts in space cannot do?ATo ask us not to take mon things for granted.BTo show they live a difficult life there.CTo show their life is boring in space.DTo introduce the topic of the text.33NASA offered $125,000 to Anjan Contractor mainly to _.Acreate some new type of 3D printerBattract more panies to work for NASAChelp astronauts in space enjoy fresh pizza one dayDproduce pizza in large quantities to earn great profits34The biggest challenge that Anjan Contractor is faced with now is probably that _.Ahe has no money left to go on with his researchBthe pizza doesnt seem appetizing to pizza loversChe has no way to make pizza that can last forthirty yearsDhe cannot make the food container last for decades35Whats the best title of the passage?ANASA is trying its best to help astronauts eat betterBAstronauts may soon be able to enjoy steaming hot pizzaCNASA is working on making pizza for mon peopleDA 3D pizza printer has been used to make pizzaFebruary has long been a month of romance. With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.On the 14th day, it is a custom for a boy to take his girlfriend out for dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals! This is what you see on Valentines Day, a day named after Valentine who was a priest (神父) in the third century Rome. When the emperor decided that single men could bee better soldiers than those with wives, he didnt allow marriage.But Valentine continued to perform marriage ceremonies for young lovers in secret. When his actions were discovered, the emperor sentenced him to death. While in prison, Valentine fell in love with the daughter of his prison guard. Before his death, he wrote her a letter, which he signed “From Your Valentine”, an expression that is still in use today. Valentine did for what he believed in and so he was made a Saint (圣徒), as well as being one of historys most romantic characters.Nowadays, Valentines Day is also popular among Chinese young people. Some students are planning to make Valentines cards for parents, teachers and friends. Others want to hold parties at which they will exchange small gifts and eat heartshaped cakes.
