5 100 点 次の英文は美紀(Miki)が書いたものです。これを読んで,あとの各問いに答えなさい。 (高知) II tell you about a "cellphone. If you use this, you can talk with your friends |anytime. You can send e-mails, listen( ① ) music and even watch TV. Many people use cellphones because they are very useful. Many young people think they can't live without cellphones. Last Sunday when I 5 was eating dinner with my mother at a restaurant, a young man and a young woman sat at the table( ② ) us. Soon they started sending e-mails on their cellphones without talking with each other. Even when they were having their dinner, they didn't stop sending e-mails. My mother said to me, “I often see young people ( ) them. They don't enjoy talking with each other. I don't think cellphones are good for 10 young people." There are other problems with cellphones. Many students with cellphones don't *spend much time with their families. When the。(child) finish eating dinner, they soon go back to their rooms and start sending e-mails to their friends. I don't have a cellphone, but my friends do. They often say to me, “Why don't you 15 have a cellphone, Miki ? If you have one, we can *exchange e-mails every night.” I was interested ( ③ ) exchanging e-mails with。them, but soon I found that there a big problem. One day one of them said to me, “I get about twenty e-mails was every night, so I need a lot of time to answer these e-mails. Sometimes I don't have time to do my homework.” I think we lose something by using cellphones too much. 20 の Let's spend a week without using cellphones. If you 2 do it, your life will *change. You can enjoy talking more with your friends. You can have a good time with your family. You can read more books. A week later, "I'm sure you will say, “I can live ( 3 ) a cellphone !" 【注) cellphone 携帯電話 anytime いつでも spend 過ごす exchange 交換する change 変わる I'm sure ~ きっと~だと私は思います [問1]( ① ) · ( ② ) · ( ④ ) · ( ③ ) · ( ③ )のそれぞれに入る語を次の中から1 つずつ選び, 記号で答えなさい。 ただし, 同じ記号を2度以上使わないこと。 (4点×5) ア like イ at ウ without エ On オ カ to キ in near 3 (

RHEED法の原理と得られる7つの情報が、この英文に書かれているみたいなのですが、よく分かりません。 分かる方助けてください!🙇‍♂️

INTRODUCTION Reection high-energy electron diHiraction (RHEED) uses a Rnely collimated electron beam with energy of 10-100 keV. The beam irradiates a sample surface with gazing incidence to obtain forward scattered difraction patterms. RHEED enables us to analyze structures of crystal surfaces at atomic levels and also to in situ monitor growth processes of thin films (mo、1988: Ichimiya and Cohen、2004: Peng et al.. 2011). From the arrangement。intensity and profile of the dilraction spots in RHEED patterns as described below in detail、 one can obtain various kinds of information: (1) the periodicity (unit cells) in atomic arrangements. (2) flat- ness of surfaces. (3) sizes of grains/domains of surface structures and microcrystals grown on the surface. (3) epitaxial relation between the grown flms/islands with respect to the substrate. (5) parameters character- izing structural phase transitions. (6) individual atomic positions in the unit cells. and (7) growth styles of thin films and numbers of atomic layers grown. The most important advantages of the method are that it is quite easy to install the RHEED apparatus in Yarious types of vacuum chambers without interfering with other components of apparatuses and to do real- time monitoring during thin-Rlm growths. Because of these advantages.RHEED is nowwidelyusednotonlyin research Iabs of surfaces and thin fims. but also in device production processes in industry Low-energy electron diiraction (LEED、see article Low-ENNERcy ErecroN DirscmoN)。 in which an electron beam of 10-100 eV in energy is irradiated onto a sample surface with nearly normal incidence to obtain back- scattered difraction patterns. is also widely used to analyze the atomic structures of crystal surfaces. Since one has to make the sample face directly to the LEED
