2、状态、情感的动词，如love, hate, like, care, respect, please, prefer, know等，若用进行时则词意改变。Im forgetting it . (=beginning to forget ) (2)表存在、状态的动词，如appear, exist, lie, remain, stand, seem等 (3)表感觉的动词，如see, hear, feel, smell, sound, taste等(4)表一时性的动词，如accept, allow, admit, decide, end, refuse, permit, promise等。三、时间状语
3、标志词atthattime/moment,(at)thistimeyesterday(lastnight/Sunday/week),at+点钟+yesterday(lastnight/Sunday), whensb.didsth 注意：1. when后通常用短暂短性动词，while后通常用持续性动词，因此它所引导的状语从句中，谓语动词常用进行时态，例如：When the car exploded I was walking past it. 我路过的时候那个车爆炸了。 While I was walking past the car it exploded. 当我路过的时候那个车爆炸了。2.
4、when用作并列连词时，主句常用进行时态，从句则用一般过去时，表示主句动作发生的过程中，另一个意想不到的动作发生了。例如： I was walking in the street when someone called me. 我正在街上走时突然有人喊我。3. when作并列连词，表示“（这时）突然”之意时，第一个并列分句用过去进行时，when引导的并列分句用一般过去时。例如： I was taking a walk when I met him. 我正在散步，突然遇见了他。We were playing outside when it began to rain. 我们正在外边玩，这时下起雨

That means that were always throwing awa
30、y old things and buying new ones. Many times, you no longer need something, but someone else may just need to buy one. For example, if your baby doesnt like his toy car any longer, why not give it to a nearly family who has a little kid? Thats one less plastic toy car that they need to buy. Its also
31、 one less plastic toy that needs to be produced, packaged and shipped to the toy store.Here arc some other ways to help the society save resources (资源):Use the other side of the paper so that less trees are cut down.Use rechargeable (可再充电的) batteries for your electric toys, MP3 players, cell phones,
32、 and cameras. Choose reusable travel cups instead of disposable (一次性的) paper or plastic cups.Take your own cloth shopping bags instead of using the plastic bags that are offered when you go shopping. Drink tap water instead of buying bottled water.And there are some things you can exchange with your
33、 friends, for example, books, toys, even clothes. Its a way for everyone to get something new without spending any money and without throwing many things away.1.

Buy everything we need instead of exchanging them with others.BAsk someone what they have done to help the
37、 environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of thatover-consumptionin the greenest way possible, but
38、 it would be far better if we did not need to bring so much material home in the firstplace. Here is an example. In the UK, the total amount of packaging increased by 12% between 2019 and 2019. It now makes up a third of a typical households waste in the UK. In many supermarkets nowadays food items
39、are packaged twice withplastic and cardboard. Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off green-house gases which go onto cause the greenhouse effect. Recycling
40、helps, but the process itself uses energy. The solution is not toproduce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannotcontinue, encouragin
41、g customers to reuse their plastic bags, for example. But this is not just about supermarkets. It is about all of us. We have learned to associate packaging withquality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it also applies to a w
42、ide range of consumer products, which often have far more packaging than necessary.There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material we are collecting. We need to face the waste of our daily life. Although many people have taken action to
43、recycle, we have a high mountain to climb. 5. What does the underlined phrase over-consumption refer to?A. Using too much packaging. B. Recycling too many wastes.C. Making more products than necessary. D. Having more material than is needed.6. The author uses figures in Paragraph 2 to show _.A. the
44、tendency of cutting household wasteB. the increase of packaging recyclingC. the rapid growth of supermarketsD. the fact of packaging overuse7. According to the text, recycling _.A. helps control the greenhouse effect B. means burning packaging for energyC. is the solution to gas shortage D. leads to
45、 a waste of land8. What can be inferred from Paragraph 4?A. Unpackaged products are of bad quality.B. Supermarkets care more about packaging.C. It is improper to judge quality by packaging.D. Other products are better packaged than food.9. What can we learn from the last paragraph?A. Fighting wastef
46、ulness is difficult.B. Needless material is mostly recycled.C. People like collecting recyclable waste.D. The author is proud of their consumer culture.CIt is an argument that has divided the East and the West for centuries: Are chopsticks better than the knife and fork, or vice versa? Now the winne
47、r may finally be decided, on environmental ground.Chopsticks are made from a variety of materials, but bamboo and wood chopsticks are more popular. They are usually cheaper, lower in temperature conduction and provide better sense for holding food. Thats why almost all disposable（一次性的）chopsticks are
48、 made of bamboo or wood. With cutting down 25 million fully-grown trees a year to make chopsticks, China has ranked number one among the producers. “We must change our habits and encourage people to take their own chopsticks when eating out,” said Mr. Bo, the owner of a forestry industry company in
49、China. He even went so far as to suggest that restaurants should offer metal knives and forks instead. If Mr. Bos suggestion is widely accepted, it would be a dark moment in chopsticks 4,000-year history.Chopsticks were invented in ancient China and later spread around Asia. They are not only used a
50、s eating tools but also used for cooking, stirring the fire and serving food. Koreans sometimes use metal chopsticks because of their love of barbecue（烧烤）. Chinese chopsticks are longer than Korean and Japanese chopsticks in order to reach the dishes in the center of the table. There are 1.4 billion
51、 people using 80 billion pairs of disposable chopsticks in China every year. However, the most widespread use of disposable chopsticks is inJapan. Around a total of 24 billion pairs are used in Japan each year,which means each Japanese uses almost 200 pairs yearly. However, most of its disposable ch
52、opsticks have been imported（进口）from China, up to over 90%. Today, China has to accept the truth that its forests can no longer provide enough chopsticks to feed Asians table habit. China is now the worlds largest importer of wood and even imports chopsticks from America. An American company said tha
53、t the states native sweet gum and poplar wood would be perfectly used to make chopsticks. These materials do not need to be lightened with chemicals or bleach（漂白粉）. The healthy materials and fairly reasonable prices of the products are appealing to Asian customers. More and more Asians start to use
54、American-made chopsticks at their tables. Although the U.S. has a huge amount of wood, reducing the number of trees that are cut down in Asia, changing the table habit of using disposable chopsticks still seems to be a wiser choice for chopsticks-using countries.10. According to Paragraph 2, Mr. Bos
55、 advice is that Chinese should _.A. use metal chopsticks instead of wooden ones B. plant more trees and produce fewer chopsticksC. form the habit of taking their own chopsticks when eating out D. change their habits and begin to use knives and forks at home11. What do we know about chopsticks in Asi
56、a?A. Koreans mainly use chopsticks to cook food over a fire.B. Most disposable chopsticks in Japan are made in China. C. The most disposable chopsticks are used in Japan yearly. D. Chinese use the shortest chopsticks to take and serve food.12. The underlined word “appealing” in Paragraph 4 probably means _. A. normal B. necessary C. attractive D. surprising13. Whats the best title for the passage? A. Time to Change the Materials for Chopsticks B. Time to Cut Down on Disposable Chopsticks C. Time to Import Disposable Chopsticks D. Time to Give Up Using Chopsticks
