gofishing钓鱼

e.g.Weoftengoshoppingonweekends.

我们经常在周末去购物。【探究总结】go+v.-ing表示“去干某事”。类似的短语有：gofishing去钓鱼goshopping去购物goswimming去游泳gohiking去徒步旅行

【学以致用】It’ssunnytoday.Let’sgo________(hunt).Languagepointshunting2.Atthattime,therewerenosupermarkets.

在那个时候，没有超市。

atthattime在那个时候。表示过去时间，因此要用一般过去时。

time的其他短语：atthistime在这个时候；atthesametime同时；haveagoodtime玩得开心；allthetime一直。

e.g.Wehadagoodtimeyesterday.Languagepoints【用法辨析】不同的“花费”take表示“花费”时，后面常跟双宾语，常用于：Ittakessb.+时间+todo

sth.“某人做某事花了多少时间”，只指“花费时间”，it为形式主语，后面的动词不定式是真正的主语Languagepoints3.Theyspentalotoftimeoutdoors.他们在户外花费大量的时间。

spend意为“用（钱）；花（钱）”，主语是人，常见句型：sb.spend…onsth./sb.spend…(in)doingsth.

e.g.Ispendfiveyuanonthebook.cost动词，表示“花费”，其过去式和过去分词是cost，主语是物，可以表示“值多少”，常见用法如下：(1)sth.costs+金钱

意为“某物价值多少”。(2)sth.costs(sb.)+金钱

意为“某物花了(某人)多少钱”。pay动词，表示“付款”，过去式是paid，主语是人，常用于词组：payfor

“为……付款”或pay(sb.)moneyforsth.“付钱(给某人)买……”Languagepoints【图解助记】①+spend+/+onsth./(in)doingsth.②+pay++forsth.③sth.+costs++④Ittakes+++todosth.Languagepoints1.It’ssunnytoday.Mr.Whiteis________(fish)atthelake.2.Manypeople______(come)totheisland(岛)alongtimeago.3.Billspendsthreehours________(watch)TVonweekends.4.Iliketoeat_______(nature)foodlikefish.5.Ican’twait________(open)thegi
