Period 4　课时学案 单元语法讲练(Learning About Language) 一、现在完成进行时的构成及用法 1．构成：have/has＋been＋doing 2．用法 (1)现在完成进行时表示动作从过去某一时刻开始一直延续到现在或离现在不远的时间，其动作是否继续下去，则由上下文而定。这个时态多用于延续性动词，如live，learn，lie，stay，sit，wait，stand，rest，study，write等，并常和all this week，this month，all night，all the morning，recently等时间状语以及since和for引导的时间状语连用(与since和for连用时，动作常会继续下去)。 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) I have been waiting for an hour and he still hasn't turned up． 我已经等了一个小时了，可他还没出现。 I've been writing letters all this morning． 整个上午我一直在写信。 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) (2)有时现在完成进行时所表示的动作并不是一直在不停地进行，而是在断断续续地重复。这时现在完成进行时可用于瞬间动词。 He's been learning since last year． 他从去年开始就一直学习。 You have been saying for a year that you will study abroad． 你一年来一直在说你要出国学习。 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) (3)现在完成进行时在上下文清楚时也可不与时间状语连用。这时现在完成进行时多指“刚才”或“近来”发生的动作，一般不再继续，并往往含有一种直接的结果。 You've been running too fast． 你跑得太快了。(直接结果可能是你现在气喘吁吁) You've been painting all day． 你画了一整天画。(暗含结果是你手上满是颜料) 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) (4)现在完成进行时和其他进行时态一样，也可以带有感情色彩。 I have been wanting to meet you for a long time． 很长时间以来，我一直想见到你。 Too much has been happening today． 今天发生太多事了。 课时提升作业 Period 4　课时学案

man is attempting to set a new record by rowing 5，000 miles solo from Hawaii to Australia while dedicating his journey to saving the planet． 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) Tez Steinberg，of Boulder，Colorado，plans to leave Hawaii on December 20 on his solo trip across the Pacific Ocean．Actually，it's the second leg of an adventure that began in 2020 when he rowed solo for 71 days from Monterey，California，to Oahu，Hawaii． Steinberg began to experience depression while he was in college．At the time，he found a solution by participating in endurance sports．“It helped me feel better，” he said．“But as I went farther and farther，pushing myself through marathons and triathlons，I discovered this belief in myself that I'm so much stronger than I thought I was．” 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) However，in 2016，his life took a big turn after the sudden death of his dad．The blow caused him to challenge himself even more by solo rowing across an ocean．After successfully completing the task without any prior professional experience，Steinberg realized he could use his story to inspire other people to believe in themselves and their potential to change and grow． 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) Recalling the first journey at sea，he said，“I was so surprised by how beautiful the ocean was，and also how much plastic I saw．So it was that realization at sea that led me to want to go back out again．” Inspired by his first expedition，Steinberg's new mission is to focus on ocean conservation，and specifically ocean plastics．“All the plastic I saw at sea was just heartbreaking，” he said． 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) The upcoming voyage will be part of an attempt to break a Guinness World Record．Nevertheless，breaking records isn't his priority．“Personally，although a world record is exciting，that's not why I'm in it．The world record is fun for media attention，but through it we can get more donations，support and action for ocean plastics，” Steinberg said． 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) 【语篇解读】　本文是一篇新闻报道。文章主要介绍了一名36岁的男子Steinberg正试图创造一项新的纪录。他计划从夏威夷划船5

A．To recover from the state of depression． B．To relieve the pain of his father's passing． C．To inspire other people to fulfil their dreams． D．To challenge himself to achieve the impossible． √ 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) B　[细节理解题。根据第四段中的“However，in 2016，his life took a big turn after the sudden death of his dad．The blow caused him to challenge himself even more by solo rowing across an ocean．”可知，为了减轻他父亲去世带来的痛苦，Steinberg进行了第一次海上探险。故选B。] 3．What is Steinberg's main purpose in setting off for the second expedition?

days from Monterey，California，to Oahu，Hawaii．”以及最后一段可知，Steinberg已经开始了独自划船穿越太平洋的计划，而且他穿越太平洋的目的是保护海洋，减少塑料垃圾。由此可推知，他是一个勇敢且有责任心的人。故选D。] Ⅱ．阅读七选五(共5小题；每小题2.5分，满分12.5分) Why does one plus one equal two？ 1 This question has been frustrating children for generations． It is quite right to feel frustrated．Math can seem like a world of rules you just have to follow． 2 However，my love of math is somewhat driven by my love of breaking rules，or at least pushing against them．Both of those impulses play an important role in advancing human understanding，and in particular mathematical understanding．So rather than think about why one plus one is two，let's go a little further and question whether it's even true all the time． 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) One plus one can equal more than two because of reproduction．Say you put one rabbit and another rabbit together．You might well end up with a lot of rabbits． 3 If one pair of tennis players gets together with another pair for an afternoon of tennis，there ends up being more than two pairs of tennis players because they could play each other in all sorts of different combinations．So one pair of tennis players plus another pair makes six pairs． 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) 4 If you put a pile of sand on top of another pile of sand，then you just get one pile of sand．Or，as an art student of mine pointed out，if you mix one color with one color，you get one color． I hope that we will start seeing mathematics as a place to pose questions and explore answers．It's not a place where the answers are fixed and we're supposed to know them．And I hope we will place more emphasis on those who are curious，and who follow their curiosity on a journey． 5 . 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) A．This is an easy question． B．It seems rigid and boring． C．Sometimes，one plus one is just one． D．One possible answer is “It just does！” E．It is a quiet walk rather than a race to the finish． F．Math isn't really about getting the right answer． G．Apart from that，things may be more complicated． [答案]　1－5　DBGCE 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) Ⅲ．完形填空(共15小题；每小题1分，满分15分) Living with a disability presents a lot of difficulties．Therefore，I have always avoided cruises (游轮)．However，this expedition-style small-ship cruise changed my mind． 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) When our expedition leader 1 we would make a Zodiac (卓迪船) 2 at Jan Mayen，a tiny island in the Arctic Ocean，I stepped out onto my balcony aboard our ship， 3 to find clear skies and calm seas． 4 ，I was met with a gust of wet wind and a view of mist-covered mountains in the distance．Jan Mayen wasn't on our itinerary (行程)，and due to its 5 location and often unpredictable weather，very few people ever 6 the island．I knew the conditions weren't 7 ，but I wasn't going to let that stop me． 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) In fact，the possibility of 8 adventures was one of the reasons I chose this small-ship cruise．So I 9 joined my shipmates in the mud room，where we put on waterproof clothes and life jackets before getting on the Zodiacs for a bumpy (颠簸的) 10 to a black-sand beach．Even the fierce wind and rain couldn't 11 our excitement as we 12 our way to the beach and hiked to a viewpoint，pausing to photograph the adorable purple flowers 13 the grey volcanic rocks． 课时提升作业 Period 4　课时学案 单元语法讲练(Learning About Language) Our visit there wasn't about what we could do or see．It was an opportunity to just be—to exist in a brief 14 on a tiny，often inaccessible，volcanic rock in the Arctic．And that's something I never thought I'd 15 in my lifetime． 【语篇解读】　本文是一篇记叙文。作者作为一名残疾人，原本因为生活中的种种困难而避免参与游轮旅行，但一次探险风格的游轮经历彻底改变了他的看法。
